3. Preamble to the description:
The following specification particularly describes the invention and the manner in which, it is to be performed.

FIELD
The present disclosure relates to the field of filtration equipment. More particularly, the present invention relates to pulp filtering equipment.
BACKGROUND
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 geometry of said filtering segments are most 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 a straight framed sector configured with a dimpled or mesh kind of segments and a funnel with square end mounted on a hollow drum or center shaft or rotor that is rotated by means of an external operator. In this configuration and design, said slurry allowed to flow over said segments in order to differentiate the water and pulp. In said conventional sector design as said slurry comes in contact with said straight dimpled segment with a bag said slurry filtered into water and pulp in a manner said pulp shall deposit over said bag and the remaining water that has to pass over said straight sector, which does not allow to flow inline to the straight surface of said dimpled or mesh kind of straight sector as required for streamline flow due to said straight geometry of said sector. Said less area of contact than the required turns the water flow into a turbulent flow. Wherein said turbulent flow germinates the issues which include but are not limited to generation of non-uniform pulp mat, creation unintended vibration in the sector, fluctuation in said frame and overall equipment, water clogging, etc. In consequence of said issues caused by said turbulent flow said straight geometry of said frame or a holding bracket fails to sustain said turbulent flow of water and reflects in catastrophes which include but not limits to the lesser strength of holding bracket results in the bending of said bracket or frame while working or during assembly, continue maintenance requirement, breakage of said bracket or sector, the decline in the performance of said disc filter, etc. Furthermore, said configuration of the straight frame or holder with the dimpled sector or meshed sector requires the clearance between said frame or holding channels and the segment, that generates more vibrations, fluctuations that lead to fatigue failure of the sheet, breakage of pulp mat before knocking off, also reduce the life of disc and frame or holding bracket. Said straight bracket also does not offer appropriate mounting and balancing because of the uneven balance of the base part configured with said rotor or drum with respect to the peripheral part or opposite open end leads to the form of additional stress within the bracket as well as at the joint with said drum, center shaft, or rotor. Whereas, in the case of a configuration wherein said sector does not comprise said separate funnel and is directly integrated within said bracket required an O ring joint in order to integrate said sector and said rotor. Wherein said O-ring joint has to be very precise in order to restrict the flow of fluid and skilled workers are intended to perform the machining and designing of said O-ring joint. Moreover, the process of manufacturing said dimpled segment involves specific dies which is time-consuming and intricate that necessitates special aids and expertise which surges the manufacturing cost with an upturn in lead time. Also, the matching of pitch is precarious.
However, as shown in figure no. P-01, a disc filter comprising a sector (P100) with a single corrugated segment (P101), wherein a corrugation (P-102) was provided at an angle or straight with respect to the vertical axis (Y) and used to transfer said filtration water from said segment (P101) to a rotor by means of a valleys (P105 and P106) formed by said corrugation (P102) on a surface in X-direction of said single segment (P-101). Wherein said flow of water from said segment (P-101) to said rotor turns into turbulent many times due to clogging conditions occurring at a lower end or rotor end (P104) because of many said valleys (P105) are intermittent, short in length, and starts from a closing channel (P103) and directed to any of side of a frame (P107) and only a few of said valleys (106) are continuous, said intermittent or short valleys (P105) starts the flows of said filtration water from said closing channel (P103) end or peripheral end and finish at any of side of said frame (P107). Said finishing of said filtration water at any of said side of said frame (P107) results into water collision with said frame (P107) which produces not only an abrupt effect on performance which includes but not limits turbulent water flow, clogging off said water flow, forming a water whirlpool which restricts bi-directional rotation, increases unintended filtration load, disturb filtration process and pulp formation, breaks the formed pulp mat, but also germinates disastrous structural issues which include but not limit to sector breakage, bending of said frame or holding bracket, breakage or bending of a disc, fracture or shredding the fastening arrangement with said rotor and/or other ancillaries, rupture of complete structure and disc filter, etc. That can lead to a severe disaster of complete equipment.
Moreover, in the case a single-segment corrugated type an unidirectional valley based sector used wherein an angled valley starts from any one of top end or from said closing channel end and end on said any one of the side of said frame towards said lower end or junction of said corrugated segment with said funnel. In this case, all valleys are projected towards the left or the right side of said frame. Further, in this configuration of said one-sided valley still, many of short or intermittent valleys exist that end on any of side of said frame and a very few valleys exist that ends at said junction said single corrugated segment and said funnel. Said uni-directional single corrugated segment causes not only said filtration water collision trouble but also it makes incompatible to configure said sector from both of sides because said pattern of said angle formed on said surface of said segment differs on both sides of said sector and does not match with other corresponding sectors. Thus, all sectors have to be configured in the same direction only that is X-direction or opposite to X-direction, and in case of any error in assembly or onsite maintenance with said configuration of patterns occurs a disc with said the uni-directional single corrugated sector will result in an adverse and disastrous effect on said performance as well as components of said disc filter.
Hence, there is a technical gap that exists is required to be fulfilled by employing a tapered sector that can provide better balancing to achieve optimum performance and alleviate the above-mentioned drawbacks.

Further, a segment configures in a manner to form said sector by means of a frame configures with said segment from the lateral side, a funnel configures with said segment from said lower end or rotor end, a closing channel configures and close said segment from said upper end or peripheral end. Whereas, said segment can be of corrugated or mesh type of surface configure with a bag or without a bag and capable to perform the filtration of said slurry as comes in contact with said segment and the surface of said segment articulated into said sector and said sector configured as said disc by depositing an amount of pulp and removing the water from said slurry. However, said frame can be tapered in cross-section gradually increasing from said upper end to said lower end in accordance with said taper cross-sectional angle. Moreover, a clamping means can be provided on top and a mounting provision articulated on said rotor in order to configure said plurality of sector with each other in order to from said disc and mount on said rotor in order to form a rotating assembly for said disc filter and assist in performing said filtration of said slurry by means of said disc filter.

DETAILED DESCRIPTION
The present invention envisages a disc filter (100) comprising; a plurality of disc (101) mounted on a rotor (102) at a specified distance as shown in figure 1, wherein said rotor (102) containing at least one flat face (121) can be articulated on a every mounting provision (122) formulated on said rotor (102) peripheral surface in order to offer said mounting provision (122) having a central circular hole called as a mounting hole (123) and a threaded hole (124) for fastening a sector (104) and aligned components assembly configured with said sector (104) coupled to a rotating means (not shown in the figure) in order to generate a rotation of said plurality of disc (101) comprising a number of said sector (104) to filter a pulp and water from a slurry. Wherein said rotation of said disc (101) can be in a direction which include but not limited to anticlockwise, clockwise, uni-directional, bi-direction, etc. The process of said filtration of said pulp and water from said slurry can commenced with the pumping of said slurry inside said disc filter (100) in order to form a contract with said rotating configuration of said disc (101) and said rotor (102) wherein said pulp deposited over a bag (103) having a series of holes (142) over a surface (103a) and corresponding opposite to X-direction on the backside of the surface of said sector (104) and allow said pulp to deposit over said surface of said bag (103a) and said water to pass from said holes (142). Wherein said deposited pulp over a surface (103a) forms a mat called pulp mat, the thicker and uniform the pulp mat the more will be the capacity to provide the better the quality of pulp and elevates the outcome of said disc filter (100). Whereas said water flowed from said bag holes (142) pass over said disc (101) comprising a plurality of said sector (104) configured with each other and mounted on said rotor (102) to form said disc (101). Said water flows over said sector comes in contact with said sector (104) and more particularly with a segment (105) in order to gradually flows from said segment (105), a funnel (107), and a pipe (109) (as shown in figure 3) configured with said rotor (102) and flowed out from the outlet (not shown in the figure). However, said pulp mat formed over said surface of said bag (103a) knocked off by showers or any other means after the completion of the rotation cycle and expelled out from pulp outlet (not shown in the figure). In another embodiment wherein said bag (103) not provided said pulp mat can be formed over a surface of said sector (104) and water can be allowed to pass from a valley (111d & 112d) in case of a corrugated segment (105) used or from holes or an aperture (206) if mesh type of sector (200) used and further knocked off by shower after completing the cycle and expelled out from said pulp outlet.
In another embodiment, as shown in figure 2, said disc (101) comprising the plurality of said sectors (104) configured with each other by means of a clamping means (120) provided on a peripheral end called an upper end (118), other end called as a lower end (119) configured with said rotating rotor (102) by means of said funnel (107), a base plate (108) and a pipe (109) assembly, and the surface of said disc (101) can be configured with said bag (103) in order to perform the filtration of said pulp and water from said slurry in a manner that said pulp allowed to deposit over said surface of said bag (103a) in order to form said pulp mat and said water pass through said holes (142) (not shown in figure 02) and gradually flow over the surface of said disc (101) in order to transfer to said rotor (102) that is rotatably configure with said disc (101). Whereas the number of said sectors (104) required in order to form said disc (101) depends on a sector angle (A) in a manner that the larger the sector angle (A) the lesser the number of said sectors (104), as well as said clamping (120) requisite in order to form said disc (101) and further lower the self-weight and cost of said configuration of said disc and rotor for the disc filter (100). Further, the increase in said sector angle (A) also decreases the number of joints required to form said disc (101) and reduces the possibility of leakage of water from the joint of said sectors (104), and assists in order to articulate more uniform and thick pulp mat, induces the better balancing of said sectors (104) that results in increase in the efficiency of said configuration of said disc (101) and said rotor (102) for the disc filter (100). In a preferred embodiment said sector angle (A) can be in the range of 18º to 32º varies in accordance with the design of said disc (101), size of said disc (101), capacity required for said disc filter (100), etc.
In a further embodiment as shown in figure 3, said sector (104) comprising said segment (105) configured within a frame (106) from the lateral side, by said funnel (107) from said lower end or rotor end (119) and closed from said upper end or peripheral end (118) by a closing channel (110). Wherein said segment (105) can be of a corrugated type constituted with at least two sheets of said segment (105) called an upper segment (111) and a lower segment (112) in order to furnish a continue valleys (111e and 112e) on the complete surface of said segment (105) in X-direction and opposite to X-direction starts from said peripheral end or said upper end (118) to end at juncture of said lower corrugated segment (112) with said funnel (107) . Wherein said continue valleys (111e and 112e) results in uniform flow of water from said upper end (118), over said complete surface of said sector (104) to said lower end of said lower corrugated segment (112) configure with said funnel (107) and ultimately to said rotor (102) via said funnel (107) and said pipe (109) assembly. Said uniform flow of said water increases the velocity of said filtration water in order to germinate the more vacuum at said peripheral end (118) and / or over said surface of said segment (105), which leads in order to to proliferating more strong suction force at said peripheral end (118) and / or over said surface of said segment (105), said strong suction force produces further potent adherence of said pulp from said slurry with said bag surface (103a) that results in more strong, more thick and more uniform pulp mat which ultimately increases the efficacy of said disc filter (100). Also, said all continue valleys (111e and 112) endures flexibility of configuration with said other sectors (104) in a manner that said sector (104) can be configure in bi-directional manner that is said sectors (104) configured in order to form said disc (101) can be assembled with corresponding said other sectors(104) in any of said X-direction or said opposite to X-direction. Wherein said bi-direction configuration of said sector (104) in said disc (101) facilitates advantage which includes but not limits to easy assembly of said disc (101), quick maintenance, said sector (104) can be used from both side for a long duration, less skilled manpower for assembly and maintenance required, enhance the service life, flexibility to re-use, etc. Further, said upper corrugated segment (111) and said lower corrugated segment (112) comprising said corrugation by means of a series of said valley (111d & 112d) and a peak (111e & 112e).
