A GUIDED DISC FILTER

PARASON MACHINERY (INDIA) PRIVATE LIMITED

AN INDIAN COMPANY HAVING ADDRESS AT
ANUKRUPA, 28, VENKATESH NAGAR JALNA ROAD, AURANGABAD MH 000000 IN

THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE SUBJECT MATTER AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

FIELD
[001] The present disclosure relates to the field of filtration equipment. More particularly, the present invention relates to pulp filtering equipment.

BACKGROUND
[002] Filtering the pulp from the slurry is a vital process that has to be performed in the paper and pulp industry. A disc filter is an equipment used to perform said filtering of said pulp from said slurry by means of a plurality of vacuum negative pressure-driven segments mounted on a rotary hollow drum or a rotor for solid-liquid separation of white-water recovery and a paper pulp thickening. In this process of said solid-liquid separation of white-water recovery and said pulp thickening, a streamlined rotation of said filtering segments is imperative and decides not only the performance and quality of said pulp mat or thickening of pulp but also the consumption of energy required to deliver the desired amount of pulp within the specified time. Whereas in the case of conventional design said disc filter, comprising a plethora of discs and comprising said plethora of discs comprising the plurality of sectors, and said plurality of sectors can be configured with a central drum or shaft which can be further configured with an operating means or motor to rotate said plurality of discs and/or said sectors with respect to the central drum or shaft. Whereas said disc configured with said shaft by means of fastening means or fasteners configured in holes provided on said disc and/or sectors with said shaft which includes clearances in order to offer a smooth configuration of said fasteners within said holes in order to configure said plurality of disc and/or sectors with said shaft or drum appropriately.
[003] However, in case of actual functioning and operating of said disc filter at full speed said disc performs the filtration of pulp from the slurry by means of allowing the water to pass from the pores of the bag configured over said plurality of disc and/or said sectors or holes provided on said disc and/or said shaft. As said water from said slurry gets discharged the remaining pulp from said slurry starts depositing over said plurality of said disc and/or said sectors. Next to said deposition of said pulp over said disc and rotation of said disc continue at full speed said loading and self-weight of said disc apply extra force on said juncture between said disc and/or said shaft and said shaft which result into the expansion of said clearances between said fasteners and holes provided on said shaft and said disc and/or said sector in order to generate vibration and jerk at the peripheral end of said disc and/or said sector. Wherein said vibration effect and jerk can increase as the length of said sector increases said vibration effect or jerk increases in order to form the fluctuation of said disc and/or sector. Further said fluctuation of said disc and/or sector impact more at the open end of said disc and/or sector due to no other configuration or fixing means available at said open end or free end of said disc and/or said sector. Whereas in case the percentage of said fluctuation is more the possibility of said disc and/or said sector sticking with said surrounding track can be neglected and in case said sector or said disc stricken with said surrounding track can result in a major accident or catastrophic failure of complete disc filter.
[004] Moreover, any one of said abrupt motions or vibrations, jerk, or fluctuation deteriorates the efficacy of said filtering by means of premature formation of pulp cake over said disc or before performing complete dewatering that results in incompletely dewatered output.
[005] Hence, there is a technical gap that is required to be fulfilled by employing a guided disc filter that can provide guided rotation of said disc filter for better balancing to achieve optimum performance and alleviate the above-mentioned drawbacks.
SUMMARY
[006] The present invention envisages A guided disc filter comprising; a rotor configured with rotating means and said disc filter, wherein a plurality of discs configured with said rotor and a sector configures with said rotor in order to form said disc. Further, a guide configured at least two said sectors by means of a groove and a configuring surface and a track configured over said configuration of said guide and said sector. However, a clearance can be maintained within said track and said guide in order to facilitate the controlled rotation of said disc for said disc filter.

OBJECTS
[007] Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
[008] An object of the present disclosure is to provide a streamlined water flow along with a uniform thicker pulp mat.
[009] In another object of the present disclosure is to facilitate the guided rotation of a disc for the disc filter.
[010] Another object of the present disclosure is to provide the frictionless rotation of disc with precise and guided entry of said disc in the track.
[011] Further, object of present invention is to configure guide with a roller configuration with disc in order achieve smooth entry and streamlined rotation of said disc within said track.
[012] Furthermore, object of the present invention is to eliminate metal-to-metal surface contact with the soft line contact in order to decrease the friction between meeting surface.

Whereas in another embodiment in the case of said sector (201) comprising ‘C’ shaped or channel type of cross-section at the configuring end of with said guide (202) or if a planner surface of said sector (201) required without any extended projection of said guide (202) in order to achieve the inline formation of pulp mat over the surface of said sector (201), as well as said guide (202), then said guide (202) can be designed with a smaller cross-section than said sector (201) in order to configure said guide (202) over said sector (201) in ‘C’ shaped or channel type cross-section in a manner said limb (209a) can be configured in a groove (201aa) and said limb (209b) of said guide (202) can be configured in a grove (201ab) of said sector (201) in order to facilitate strong hold over said sector (201) in order to configure said sector (201) with another same or similar type of sector (201) as required in order to formulate said disc (200). Furthermore, said sector (201) can be configured with said guide (202) by means of fastening means which include but not limited to fasteners, rivets, dowels, etc. However, said fastening can be done in a manner where at least one fastener can be configured in at least one of said sectors (201) whereas the other end of said sector (201) can be aligned in the groove (207) of said guide (202) and supported by means of configuration extended by other ends of said guide (202) configured with another same or similar type of said sector (201). In another embodiment said guide (202) can be configured with both of said configuring sectors (201) by means of the two-point fastening provision provided in said guide (202).
[038] In another embodiment as shown in figure no.07 to 10 said guide (202) comprising said limb (209) separated by means of said groove (202) in a manner to form at least two limbs (209a and 209b). Wherein the geometry of said groove (207) at a surface (208) can be articulated in a manner to accommodate the configuring shape of said sector (201) at the juncture of said sector (201) and said guide (202). In one of the preferred embodiments said groove (207) can be of C or U type and sufficiently deep in order to configure said sector (201) firmly within. In another preferred embodiment, the depth of said groove (207) can be at least 15 mm from the configuring surface (208) of said guide (202). Further, the ends (210a, 210b) of said guide (202) can be of shape which includes but not limited to curved, U-shaped, curvilinear, concave, or convex type in shape in order to facilitate smooth configuration of said sector (201) from both ends (210a, 210b) of said guide (202). Wherein said guide (202) can be configured in a manner that one end (210a) of said guide (202) can be configured with said sector (201) and another end (210b) opposite to first configured with said end (210a) can be configured with another same or similar type of sector (210). In one of the preferred embodiments said end (210) can be curved in shape in order to avoid sharp corners to reduce the possibility of stress concentration, crack formation, causing injuries to the operator, etc. at the edge of said guide (202). Furthermore, said guide (202) can be configured with said sector (201) by means of configuring said fastener in a hole (213). Whereas if required a hole (211) and a hole (212) can also be configured with said fastening means in order to provide extended strength to said configuration of said guide (202) and said sector (201) in order to formulate strong and rigid disc (200). In one of the embodiments, at least 3 number of holes (211, 212, 213) can be articulated on said guide (202). However, an external surface (204, 205) can be furnished in the vertical and horizontal grooved manner in accordance with the configuration of said soft part (214) (as shown in figures no. 11 and 12). In one embodiment at least one number of said vertical and horizontal grooves can be furnished on said external surface (204, 205).
[039] In further, embodiment as shown in figures no. 11 and 12, said configuration of said sector (201) and said guide (202) within said track (203) can be configured by means of said soft part (214) in order to minimize the clearance (206) between said configuration of said sector (201) and said guide (202) and said track (203) in order to offer the close rotation for said disc (200). Wherein said soft part (214) can be configured with said external surface (204, 205) of said guide (202) in a manner to project externally from said external surface (204, 205). Said external projection of said soft part (214) from said surface (204, 205) of said guide (202) extends outwardly from said guide (202) towards said track (203) in order to reduce the clearance (206). Said application of said soft part (214) in order to achieve a close run for said disc (200) in order to formulate a more uniform and streamlined pulp mat over said disc (200) in order or increase the efficacy of said disc filter (100) and perform said dewatering more effectively in order to increase the efficiency of said disc filter (100). Further, in case of any vibration or misalignment between said disc filter (100) configuration or formulation of said disc (200) that results in the formation of unintended vibration or jerk during rotation of said disc (200) within said track (203) which can consequence into striking or galling said disc (200) with said track (203). Said galling increases as the distance of said disc (200) increases from said shaft (102) and can be maximum at the top or external periphery of said disc (200) in order to cause maximum galling of said guide (202) configured at the top of said disc (200) in order to configure said plurality of sector (201) with each other and in order to provide guided rotation of said disc (200) to protect not only said sector (201) and said disc (200) but also said track (203) from said galling and other damages caused by means of said galling. Further, due to said galling action of said disc (201) said guide (202) the rotation of said disc (200) generates friction between said disc (200) and said track (203) to increase the rotational load and surge into energy consumption with degradation of pulp quality. Furthermore, as said guide (202) configured on the periphery of said disc (200) wherein the maximum galling action occurs leads to damage said guide (202) and protects said disc (200) and/or said plurality of sectors (201) from damage to replace said damaged guide (202) due to falling with another guide (202). However, in case of the configuration of said soft part (214) with said guide (202) can reduce the impact of said galling action of said disc (200) and protect said guide (202) from damage by means of replacing metal-to-metal friction caused by means of galling of said disc (202) and said track (203) with metal to nonmetal friction caused due to galling of said soft part (214) with said track (203). Further, the implication of said soft part (214) reduces the galling and friction of said disc (200) and/or said guide (202) and controls sudden rise in energy demand due to galling action as well as acts as vibration dampening agent to safeguard the deterioration of pulp quality and pulp mat formation that can affect adversely due to unintended vibration and galling of said disc (200) and/or said guide (202). Moreover, said soft part (214) can be easily replaced after wear and tear of said soft part (214) due to galling without removing said guide (202) from said disc (202) in order to reduce the downtime of removing and configuring said guide (202) with said disc (202) and replacement cost of said guide (202) due to damage of said guide (202) by means of said galling. In one of the preferred embodiments said soft part (214) can be the non-metallic part which includes but not limited to an O-ring, gasket, rubber block, etc.
[040] In another embodiment, as shown in figures no. 13 to 16, a guide (302) can be configured with a rolling means (301) instead of said soft part (214). Wherein said rolling means (301) can be configured on a top surface (304) of said guide (302) opposite to the configuration of said guide (302) with said disc (300) by means of configuring fastening means with said holes (311, 312) (not as shown in figure) articulated on said top surface (304) and further said guide (302) can be configure with said sector (301) by means of fastening configuration in manner to insert said fastener within a hole (313). Said rolling means (301) can be configured with said guide (302) in a manner to an extended part (305) can be equally project outside of said top surface (304) of said guide (302) towards said track (303) in order to symmetrically reduce said clearance (306) between said disc (300) and said track (303) to offer closed run for said disc (300) between said track (303). Whereas said configuration of said rolling means (301) on said top surface (304) of said guide (302) further assists in reducing the effect of said galling by means of replacing surface contact formed by said guide (302) and/or said disc (300) and said track (303) with the point contact formed by means of said rolling means (301) with said track (303) in order to further reduce or eliminate the friction between said disc (300) and said track (303) caused due to said galling action to reduce or eliminate the adverse impact of said galling on the efficacy and efficiency of said disc filter (100). In one of the preferred embodiments said rolling means (301) can be circular in shape with the material user can be non-metallic material which includes but not limits to plastic, rubber, fiber, etc. In another preferred embodiment, the overall size and rolling diameter of said rolling means (301) can be larger than the cross-section and/or said top surface (304) of said guide (302). However, said rolling means (301) configuration of said guide (302) can assist in smooth entry and configuration of said guide (302) within said track (303) and facilitate more streamlined rotation of said disc (300) within said track (303). Moreover, said rolling means (301) can be easily replaced after wear and tear or in case of damage of said rolling means (301) due to galling without removing said guide (302) from said disc (300) in order to reduce the downtime of removing and configuring said guide (302) with said disc (300) and replacement cost of said guide (302) due to damage of said guide (302) by means of said galling. Moreover, it's apparent to the person skilled in the art that other configurations relating to said guide (302) which include but not limits to said clearance (306), a groove (307), a configuring surface (308), a limb (309a), a limb (309b), an end (310a), an end (310b) can be configured in accordance with said guide (202) configured with said disc (200).
