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 dewatering pulp from slurry. More particularly, the present invention relates to the dewatering method and device made for said dewatering.
BACKGROUND
Dewatering the pulp from the slurry is a vital process that has to be performed in the paper and pulp industry. Wherein a plurality of equipment used to perform said dewatering of said pulp from said slurry by means of a plurality of separation process and /or process or device of vacuum negative or atmospheric pressure-driven segments mounted on a rotary hollow drum or a rotor for solid-liquid separation of water recovery and a paper pulp thickening from said dewatering. In this process of said solid-liquid separation of water recovery and said pulp thickening, the method and device for said dewatering are most imperative and decide 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 the conventional dewatering method, said slurry use to feed directly into said filtering devices which include but not limits to a disc filter or a drum filter, and the process converts into pulp with an average grade of consistency.
Further, said filtering process is performed by means of un-processed slurry directly fed into the filtering devices which include but not limited to said disc filter and/ or said drum filter that is configured with normal filtering cloth with a filtering surface comprised of soft material made of material PP, PET, PA, polyethylene, etc. wherein said filtering of said pulp from said slurry by means of filtering bag configure with said filter. Wherein said filter bag can have pores on a surface that allows water to pass and restrict pulp in order to settle on the surface of said soft filtering bag in order to form multiple layers of said pulp to form a pulp cake for further processing. Whereas said soft filtering bag with said filtering surface with pores to pass water and allow the pulp to settle on the surface is more reluctant to damage due to any solid contamination more specifically iron parts. Whereas the possibility of said iron part exists high in case of said unprocessed slurries that can form contact with said filtration cloth and damage same. Furthermore, said filtering cloth surface has the plane surface as a disc surface of said disc filter or a drum in the case of said drum filter. Said filtering cloth surface provides output less than that of said disc surface with a more rigid and bulky structure as said filtering cloth is confined with said disc or drum of filtering devices and needs strong support to hold said filter cloth along with said formed pulp cake on said surface of said disc or drum filter. Moreover, said bulky filtering process structure operates with jerky and overloaded movement with an average output with more power requirement. This leads to fluctuated rotation of said disc with a plethora of failures which include but not limits to the bending of said disc and sectors or said drum, fatigue failure of said filtering devices and sectors, and less life of said filtering bag and said filtering equipment with continuous maintenance requirements.
Hence, there is a technical gap that exists and needs to alleviate by means of effective, and efficient dewatering methods and dewatering devices.

In another embodiment said thicker yarn (405a) can be formulated in order to include magnetic and/or electrolysis-type properties. Wherein said magnetic and/or magnetic properties can be included in said thicker yarn (405a) by the blending process. In one of the preferred embodiments, the diameter of said thicker yarn (405a) can be larger than the other types of yarns (403, 404, 405) and can be in the range 0.6 to 0.9 mm. Moreover, said thicker yarn (405a) can be configured at least with said lower surface (402) at least one thicker yarn (405a) per binding point (406, 407, 408) in or order to increase the strength of said binding point (406, 407, 408) and/or bag (400) to sustain said pulp load on said filtering surface in order to more effectively without a bulky frame or filtering device (101) structure that reduces the self-weight of said filtering device (101) and/or dewatering device (101) and assist more streamlined and uniform pulp mat. In one of the preferred embodiments multiple corrugations (409) can be formed across said bag (400) at least at said upper surface (401) with respect to a binding point (406, 407, 408) for example first corrugations (409) can be formed between said binding points (406 and 407), second similar type of corrugation (409) can be formed between said binding points (407 and 408) and continue respectively.
In furthermore embodiment as shown in figure no. 10, a bag (500) comprising a bag surface (501) supported by means of a plurality of non-shrinkable yarns (503, 505) and a lower surface (502) can be formed of combined a shrinkable (504) and said non-shrinkable yarns (503, 505) respectively. Wherein said upper surface (501) and said lower surface (502) are configured in a manner to generate a corrugation (509, 509’) under the application of heating means. Whereas said corrugation (509) can be formed with respect to said upper surface (501) and said corrugation (509’) can be formed with respect to said lower surface (502). In one of the embodiments said corrugation (509, 509’) can be formed on both sides by the effect of shrinking only said shrinkable yarn (504) without shrinking any other types of said yarn (503, 505). Further, as said shrinkable yarn (504) squeezes said non-heat shrinkable yarns (503) configured with said upper surface (501) and said lower surface (502) simultaneously converges into the formation of said corrugation (509) on said upper surface (501) and said corrugation (509’) on said lower surface (502) in order to facilitate dual corrugation effect to increase corrugation efficacy for said dewatering device (100). In one of the preferred embodiments, multiple corrugations (509, 509’) can be formed across said bag (500) with respect to a binding point (506, 507, 508) for example first pair of corrugations (509, 509’) can be formed between said binding points (506 and 507), second pair of corrugation (509, 509’) can be formed between said binding points (507 and 508) and continue respectively. However, said dual corrugation (509, 509’) increases the filtering area, with dual filtration capacity and alleviates the formed pulp for said filtering device (101) in order to increase the filtering and dewatering capacity for said dewatering device (100).
However, said thickness and formation of said pulp increase by means of an increase in pulp formation in said filtration process that depends on the surface area of said bag (106, 200, 300, 400, 500) as well as said disc or drum of said filtering device (101). In the present invention, a corrugated bag (106, 200, 300, 400, 500) configured with said filtering device (101) in a manner said bag (106, 200, 300, 400, 500) can be slightly larger in dimension as compared to said filtering disc and/or drum (104) and required configuration with said filtering sector or drum (105) of said filtering device (101) by means of applying heat on said bag (106, 200, 300, 400, 500). In one of one of the preferred embodiments said bag can be 2 to 10% larger in size as compared to said sector and/or disc of said disc filter and/or said drum filter. As said heat is applied on said corrugated bag (106, 200, 300, 400, 500) said filtering surface (201, 301, 401, 501, 502) of said bag (106, 200, 300, 400, 500) turns into a corrugated surface (209, 309, 409, 509, 509’) by means of shrinking of bottom yarns (204, 304, 404, 504) and cake formation is processed on said corrugated surface (209, 509, 509’) by filtering water from pores of said corrugated bag (106, 200, 300, 400, 500). Wherein said corrugation effect (209, 309, 409, 509, 509’) increases the open area for said bag (106, 200, 300, 400, 500) in the range of 2% to 30 % and increases the filtering efficiency for said dewatering device (100). Said corrugation forms (209, 309, 409, 509, 509’) can be in the direction in order to facilitate smooth rotation to said filter disc and/or drum (104) along with the formed cake and filter bag. Said increased corrugation surface (209, 309, 409, 509, 509’) increases pulp formation quantity, said increased open area by means of corrugation (209, 309, 409, 509, 509’) and stretching of yarns (204, 304, 404, 504) improves the quality of said pulp, said smooth rotation of said disc and/or drum (104) reduces power consumption and increases output for said dewatering method and device made of said dewatering method thereof (10)
