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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] In the present utility model, if Figure 1-3As shown, a filter cage for sludge filter pressing is provided, including a filter cage body 101, wherein the filter cage body 101 has a compression chamber with an open top, a side wall of the filter cage body 101 is provided with a plate wall 102, and a fixing plate 2 is detachably installed on the bottom wall of the filter cage body 101 near the plate wall 102, and the fixing plate 2 can clamp and fix the filter cloth 10.

[0028] As shown in the figure, when the filter cloth 10 needs to be removed from the bottom of the filter cage 1, the fixing plate 2 can be removed from the bottom wall of the filter cage 1, and then the fixing plate 2 is taken out, and then the filter cloth 10 is separated from the fixing plate 2. At this time, the filter cloth 10 can be replaced so that the filter cloth 10 is fixed on the lower side of the fixing plate 2, and then the fixing plate 2 is installed at the bottom wall of the filter cage 1, so as to solve the problem that the operation space at the bottom wall of the filter cage 1 is small and it is not easy to fix the filter cloth 10. By fixing the fixing plate 2 at a position close to the plate wall 102, so that the bottom of the filter cloth 10 is close to a side wall of the filter cage 1, the sludge on the upper side of the filter cloth 10 can be moved toward the plate wall 102 when the filter cloth 10 is straightened, so as to facilitate the collection and cleaning of the sludge on one side of the filter cage 1.

[0029] In a preferred embodiment, the plate wall 102 can be set to be openable and closable, so that when the filter cloth 10 needs to be cleaned and inspected, the plate wall 102 can be opened to provide sufficient operating space at the plate wall 102 position when the filter cloth 10 reel (as shown in the upper left part) is rolled up and the filter cloth 10 is lowered, so as to facilitate operation. Moreover, the fixed plate 2 is set at a position close to the plate wall 102, and the plate wall 102 can be opened when the fixed plate 2 is disassembled and installed to facilitate operation. As for the opening method of the plate wall 102, as a preferred embodiment, the plate wall 102 can be set to a form that can slide along the extension direction of the vertical fixed plate 2, and the plate wall 102 is driven to move by an oil cylinder, an electric telescopic rod or a gear rack mechanism. Alternatively, the plate wall 102 can also be set to a form that is hinged with the filter cage 1 to facilitate opening the plate wall 102. Alternatively, the plate wall 102 is set to a form that can slide along the extension direction of the fixed plate 2.

[0030] In a preferred embodiment, as shown in the figure, the bottom of the fixing plate 2 clamps and fixes the filter cloth 10, and the filter cloth 10 can be wound around the upper side of the fixing plate 2 from the side of the fixing plate 2 facing the plate wall 102. By fixing the filter cloth 10 at the bottom of the fixing plate 2, a fixing structure for the filter cloth 10 can be set at the bottom of the fixing plate 2 to prevent the remaining water from entering the fixed structure position of the fixing plate 2 when the sludge is filtered, and some iron connecting parts (such as bolts 3) are used to prevent the iron parts from rusting.

[0031] In a preferred embodiment, for the structure of the utility model, more specifically, the fixed plate 2 includes an upper plate body 201 and a lower plate body 202 detachably connected to the lower side of the upper plate body 201, and the lower plate body 202 is fixedly connected to the upper plate body 201 by bolts 3.

[0032] In the illustrated embodiment, for the structure of the utility model, more specifically, the bottom of the upper plate 201 is provided with a fixing groove 4, and the lower plate 202 is installed in the fixing groove 4. As shown in the figure, by providing the fixing groove 4, water can be further prevented from entering the bolt 3 position.

[0033] In the illustrated embodiment, for the structure of the utility model, more specifically, a rubber layer 5 is provided between the upper plate 201 and the lower plate 202. In this way, the friction force when the filter cloth 10 is fixed can be increased by the rubber layer 5, thereby improving the fixing effect of the filter cloth 10 and preventing the filter cloth 10 from sliding.

[0034] In the illustrated embodiment, the present invention is further optimized in that at least one of the surface of the upper plate 201 facing the lower plate 202 and the surface of the lower plate 202 facing the upper plate 201 is provided with anti-slip grooves. By providing the anti-slip grooves, the anti-slip grooves can be used to form concave and convex patterns at the position of the rubber layer 5 when the filter cloth 10 is fixed, thereby further increasing the friction force for fixing the filter cloth 10.

[0035] In a preferred embodiment, the present invention is further optimized in that the top surface of the fixing plate 2 is inclined downward along a section toward the plate wall 102. In this way, when the filter residue on the upper side of the filter cloth 10 is discharged, the filter residue on the upper side of the filter cloth 10 can be discharged more thoroughly.

[0036] In a preferred embodiment, the utility model is further optimized in that one end of the fixing plate 2 facing the plate wall 102 is arranged in an arc shape. As shown in the figure, the filter cloth 10 can extend upward around the arc structure at the fixing plate 2 position, thereby reducing the occurrence of the working condition where the filter cloth 10 is subjected to concentrated force at the fixing plate 2 position, and increasing the service life of the filter cloth 10.

[0037] Regarding the installation method of the fixing plate 2, in the illustrated embodiment, more specifically, as shown in the figure, the bottom wall of the filter cage 1 is provided with a positioning groove 6 for inserting the end of the fixing plate 2; the side of the filter cage 1 is provided with a socket 7, and the filter cage 1 also includes a pin 8, which is inserted into the end of the fixing plate 2 from behind the socket 7.

[0038] As shown in the figure, when installing the fixing plate 2, it is only necessary to insert the two ends of the fixing plate 2 into the positioning grooves 6 from top to bottom, and then insert the latch 8 horizontally into the insertion hole 7 of the filter cage 1 and then insert it into the end of the fixing plate 2, which is easy to operate. When removing the fixing plate 2, it is only necessary to remove the latch 8 and then lift the fixing plate 2 upwards.

[0039] In a preferred embodiment, a further optimized configuration of the structure of the utility model is that the inner end of the latch 8 is provided with a thread, and the latch 8 is screwed and fixed to the fixing plate 2. This can improve the stability of the fixing of the latch 8.

[0040] It should be noted that, in the illustrated embodiment, the fixed plate 2 also clamps and fixes a partition layer 9 at a section away from the plate wall 102, and the partition layer 9 is wound on a partition layer 9 reel. When the filter cloth 10 is pressed, the partition layer 9 is located between the filter cloths 10 to separate the filter cloths 10 at the upper and lower sludge positions, thereby reducing the adhesion between the filter cloths 10. In this way, the partition layer 9 can be fixed by the fixed plate 2 at the same time. In an optional embodiment, the partition layer 9 may not be provided, and the fixed plate 2 only fixes the filter cloth 10.

[0041] 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.

[0042] 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.
