[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0022] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0023] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0025] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0026] In the present utility model, if Figure 1-4 As shown, a separator cloth structure for sludge filter pressing is provided, comprising a separator cloth body 1 that can be rolled and deformed, the separator cloth body 1 having a separator surface, the separator cloth body 1 forming a material storage area 2 in the middle of the separator surface, and water guide areas 3 on both sides of the material storage area 2; the separator cloth body 1 is provided with a water guide groove 4 in the water guide area 3.

[0027] When the partition cloth structure of the utility model is used, Figures 1 to 3As shown, when the filter cloth 8 is folded into an S shape, the separator cloth body 1 is also folded into an S shape accordingly, so that after the filter cloth 8 is spread with sludge, the separator cloth body 1 is placed between two layers of sludge to be filtered. During the sludge filtration process, the sludge is gradually thinned and flattened laterally in the material storage area 2. The filter water generated in this process flows laterally outward in the material storage area 2 of the dividing surface, and quickly flows out through the water guide groove 4 in the water guide area 3, thereby reducing the vertical infiltration flow path of the filter water between the filter cloths 8 and improving the filter pressing efficiency.

[0028] Moreover, the use of the separator cloth body 1 can also separate two adjacent filter cloths 8 when the filter cloth 8 is unfolded for cleaning after the filtration is completed, so as to prevent the problem of compensation of the unfolding of the filter cloth 8 caused by the adhesion of two adjacent filter cloth layers 8 due to the seepage mud.

[0029] In a preferred embodiment, a further optimized setting of the utility model is that the thickness of the partition cloth body 1 in the water guide area 3 is greater than the thickness of the partition cloth body 1 in the material storage area 2. By making the thickness of the water guide area 3 greater than or equal to the thickness of the partition cloth in the material storage area 2, during the sludge filtration process, as shown in the figure, the water guide area 3 forms a lateral constraint on the lateral flow of the sludge, so as to suppress the tendency of the sludge to flow outside the water guide area 3, which can then facilitate the sludge to be filtered and spread evenly at the material storage area 2 of the dividing surface.

[0030] exist Figure 1-4 In the embodiment shown, the utility model is further optimized in that the partition cloth body 1 is provided with arcuate ridges 5 at intervals in the water guide area 3, and the water guide grooves 4 are formed between the adjacent arcuate ridges 5. As shown in the figure, by providing the arcuate ridges, the thickness difference of the protruding parts of the arcuate ridges 5 formed in the material storage area 2 can be utilized, and the water guide grooves 4 are formed between the arcuate ridges 5, so that the width of the water guide grooves 4 gradually widens outward, and thus the filter cloth 8 between the partition cloths is easily released when the partition cloth body 1 is unfolded.

[0031] In the illustrated embodiment, a further optimized configuration of the present invention is that the height of the arc-shaped convex strip 5 gradually increases from the inside to the outside. Figure 4 As shown, the thickness of the separator cloth can be gradually changed between the material storage area 2 and the water guide area 3 to reduce the thickness distortion of the separator cloth during filtration, so that when the sludge flows horizontally at the filter cloth 8 during sludge filtration, it can be gradually constrained in the water guide area to reduce the amplitude of sludge flow in the direction perpendicular to the arc ridge 5, further preventing the sludge from flowing out of the outside of the filter cloth 8.

[0032] In the illustrated embodiment, a further optimized setting of the present invention is that the width of the arc-shaped strip gradually increases from the inside to the outside. Figure 2As shown, when part of the sludge is pressed into the arc-shaped strip area, the restriction on the sludge flowing outward gradually increases, further preventing the sludge from flowing out of the filter cloth 8.

[0033] exist Figure 2 In the illustrated embodiment, more specifically, the partition cloth body 1 forms a waterproof layer on the partition surface, and the partition cloth body 1 is provided with water-permeable holes 6 at the edge of the material storage area 2.

[0034] exist Figure 2 In the embodiment shown, specifically, waterproof layers are provided on both sides of the partition cloth, and water-permeable holes 6 are provided at the edge of the material storage area 2, so that when the water generated by the sludge filtration flows horizontally to the water guide groove 4, it can flow vertically at the position of the water-permeable holes 6, so that when the drainage speed of the drainage channel is reduced due to squeezing of part of the water guide groove 4, the drainage speed is accelerated by vertical drainage. In addition, it can also prevent the working condition that the water accumulation caused by the bending of the partition layout due to the thickness distortion between the water guide area 3 and the material storage area 2 is difficult to drain.

[0035] In a preferred embodiment, the utility model is further optimized in that the partition cloth body 1 is provided with water-permeable holes 6 in the water-conducting area 3. This can further improve the drainage efficiency when draining water outward during the filter pressing process.

[0036] In a preferred embodiment, a further optimized configuration of the present invention is that the separator cloth body 1 is provided with a plurality of stop protrusions 7 at the edge of the material storage area 2 .

[0037] like Figure 2 and 4 As shown, the stop protrusion 7 is configured as an arc-shaped protrusion, so that during the sludge filtration process, the stop protrusion 7 can be used to divide and restrain the lateral movement of the sludge, thereby increasing the resistance to the lateral flow of the sludge, thereby preventing the sludge from being concentratedly flowed toward one side of the dividing cloth during the filtration process, thereby preventing the sludge from flowing out of the outside of the dividing layer.

[0038] In a preferred embodiment, for the structure of the utility model, more specifically, the waterproof layer is configured as a polyurethane waterproof layer.

[0039] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0040] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
