[0026] Embodiment 1: Figure 1-4 It can be seen that a filter press device for coal slime includes a frame 1, one end of the inner wall of the frame 1 is fixedly connected with a thrust plate 13, the other end of the frame 1 is fixedly connected with a hydraulic cylinder 23, the model of the hydraulic cylinder 23 is YGC, the output end of the hydraulic cylinder 23 is fixedly connected with a pressing plate 21, the inner wall of the frame 1 is provided with a plurality of filter plates 18, and a flushing device is provided above the filter plate 18, the flushing device includes a two-way cleaning pipe 14, a first electric slider 15, a cylinder 16, a first electric slide rail 17 and a straight plate 22, the straight plate 22 is fixedly connected to the top of the hydraulic cylinder 23, the first electric slide rail 17 is fixedly connected between the straight plate 22 and the thrust plate 13, the outer wall of the first electric slide rail 17 is installed with a first electric slider 15, the models of the first electric slide rail 17 and the first electric slider 15 are RXP45, the bottom of the first electric slider 15 is fixedly connected with a cylinder 16, and the output end of the cylinder 16 is fixedly connected with a two-way cleaning pipe 14;

[0027] In the specific implementation process, it is worth pointing out that after the coal slime filter press has performed a coal slime filtration operation, since the squeezed filter cake needs to be removed, there is already a gap between the filter plates 18 and the filter plates 18. The first electric slide rail 17, the first electric slider 15 and the cylinder 16 are started, and the two-way cleaning pipe 14 at the bottom of the cylinder 16 is placed between the two filter plates 18. Driven by the cylinder 16, the two-way cleaning pipe 14 can clean the filter cloth 20 on both sides from top to bottom. After cleaning, the two filter cloths 20 are cleaned under the drive of the first electric slide rail 17 and the first electric slider 15, which shortens the manual operation time and provides cleaner filter cloths 20 for the next filtration operation.

The delivery end of the water pump 9 passes through the side of the storage barrel 10;

[0031] In the specific implementation process, it is worth pointing out that the liquid squeezed out by the compression plate 21 flows into the delivery pipe 11 from the first circular hole 19 on the filter plate 18 in the form of undercurrent, and finally flows into the interior of the storage barrel 10 through the delivery pipe 11 for storage. When the liquid in the storage barrel 10 needs to be taken out, the water pump 9 is started to pump out the liquid.

[0032] Specifically, when the coal slime filter press device is used, during the coal slime filter press operation, the hydraulic cylinder 23 is started, and the plurality of filter plates 18 are pushed toward the thrust plate 13 through the pressing plate 21. When the pressure of the hydraulic cylinder 23 reaches a sufficiently large MPa, the gate valve 7 is opened, and the coal slime flows into the hose 12 through the feed pipe 8, and finally flows into the second circular holes 2 in each filter plate 18 through the hose 12, and finally flows into the filter cloth 20. The squeezed water flows into the conveying pipe 11 through the first circular holes 19 in the form of undercurrent, and the filter cake formed by the squeeze remains in the filter chamber formed between the filter plates 18 and the filter plates 18. The liquid squeezed out by the pressing plate 21 flows into the conveying pipe 11 from the first circular holes 19 on the filter plates 18 in the form of undercurrent. , finally flows into the interior of the storage barrel 10 through the delivery pipe 11 for storage. When it is necessary to take out the liquid in the storage barrel 10, start the water pump 9 to extract the liquid. After the coal slime filter press has performed a coal slime filtration operation, since the squeezed filter cake needs to be removed, there is already a gap between the filter plates 18 and the filter plates 18. Start the first electric slide rail 17, the first electric slider 15 and the cylinder 16, and place the two-way cleaning pipe 14 at the bottom of the cylinder 16 between the two filter plates 18. Driven by the cylinder 16, the two-way cleaning pipe 14 can clean the filter cloths 20 on both sides from top to bottom. After cleaning, the two filter cloths 20 are cleaned under the drive of the first electric slide rail 17 and the first electric slider 15.

[0033] Embodiment 2: By Figure 1-4 It can be seen that the front of the frame 1 is fixedly connected with an air intake pipe 5, the top of the air intake pipe 5 near the gate valve 7 is installed with a diaphragm air intake valve 6, the other end of the air intake pipe 5 is installed with a diaphragm exhaust valve 24, the top of the air intake pipe 5 is connected with a plurality of air delivery pipes 4, and the delivery end of the air delivery pipe 4 is connected to the front of the filter plate 18;

[0037] Furthermore, the bottoms of the thrust plate 13 and the hydraulic cylinder 23 are fixedly connected with four pillars 33, and the receiving plate 3 is fixedly connected between the four pillars 33;

[0038] In the specific implementation process, it is worth pointing out that after repeated operation of the clamping block 27, a gap appears between the filter plates 18 and the filter plates 18, and the filter cake on the surface of the filter cloth 20 will automatically fall off to the top of the receiving plate 3, which is convenient for collecting the filter cake;

[0039] Specifically, on the basis of the above-mentioned embodiment 1, after a filter cake is formed between the filter plates 18 and the filter plates 18, one end of the air inlet pipe 5 can be connected to an external gas transmission device through a flange, and the diaphragm air inlet valve 6 is opened.

When the block 27 passes through the bracket 29, it will immediately recover. Then, driven by the second electric slider 32, the filter plate 18 can be moved horizontally. By repeating the operation, a gap can be left between the filter plates 18 to facilitate the falling of the filter cake. After repeated operation of the block 27, a gap will appear between the filter plates 18, and the filter cake on the surface of the filter cloth 20 will automatically fall off to the top of the receiving plate 3, which is convenient for collecting the filter cake.
