During operation, the suspension is pumped into each plate-frame filter chamber through the feed port and filtered under the pressure given by the squeeze plate 51. Solid particles are trapped on the filter cloth to form a filter cake, while the liquid is discharged through the liquid outlet until all the plate-frame filter chambers are filled with filter cakes.

[0021] like Figure 1 As shown, one of the brackets 2 of each filter press is connected with a delivery branch pipe, and the first delivery pipe 11 is connected to the filter frame plate assembly 4 of one filter press through a delivery branch pipe, and is connected to the filter frame plate assembly 4 of another filter press through another delivery branch pipe. Delivery valves are respectively provided on the two delivery branches, and the on-off of the delivery pump 1 to the corresponding filter press is controlled by controlling the on-off of the delivery valve. A liquid outlet pipe 21 connected to the liquid outlet is provided on one of the two brackets 2 of each filter press, and the liquid discharged from the liquid outlet of the filter frame plate assembly 4 is discharged through the liquid outlet pipe 21. A slag receiving pan 6 is provided between the two brackets 2, and the slag receiving pan 6 is located directly below the filter frame plate assembly 4. When the filter pressing work is completed, the filter cake falls after the filter frame assembly 4 is separated and is caught by the slag receiving pan 6. The slag receiving pan 6 is detachably connected to the bracket 2, and the slag receiving pan 6 is taken out for processing when the filter cake is full.

[0022] like Figure 1 and Figure 2As shown, the first storage tank 7 and the second storage tank 8 are both transversely arranged tank bodies, the first storage tank 7 is arranged between the two brackets 2 of the left filter press, and the second storage tank 8 is arranged between the two brackets 2 of the right filter press, and the two storage tanks are located below the corresponding slag receiving plate 6. The two storage tanks are connected to the bracket 2 to increase the stability of the bracket 2 and improve the overall structural strength of the whole; the inlet end of the delivery pump 1 is connected to the first storage tank 7 through the first feed pipe 71, and is connected to the second storage tank 8 through the second feed pipe 81. The first feed pipe 71 and the second feed pipe 81 are respectively connected to the side bottom of the corresponding storage tanks, and the first feed pipe 71 and the second feed pipe 81 are respectively provided with feed pipe valves, so that the delivery pump 1 can choose to pump out the suspension from the first storage tank 7 or the second storage tank 8. The output end of the delivery pump 1 is connected to the first storage tank 7 through the first circulation pipe 72, and is connected to the second storage tank 8 through the second circulation pipe 82. The first circulation pipe 72 and the second circulation pipe 82 are respectively provided with circulation pipe valves. The suspension can be circulated and delivered back to the first storage tank 7 or the second storage tank 8 by opening and closing the circulation pipe valves.

The liquid in the liquid outlet pipe 21 is transported back to the two storage tanks to reduce the solid content in the storage tanks and reduce the possibility of siltation at the bottom of the storage tanks.

[0024] like Figure 1 and Figure 2 As shown, the first storage tank 7 and the second storage tank 8 are both provided with a stirring device, which includes a stirring motor 74, a stirring shaft and a stirring paddle 75. The stirring paddle 75 is arranged horizontally in the storage tank, and the stirring paddle 75 is connected to the stirring shaft through a connecting rod 76. The stirring motor 74 can drive the stirring paddle 75 to work to prevent the suspension from settling in the storage tank.

[0025] like Figure 1 and Figure 2As shown, in order to improve working efficiency, when one filter press enters the cake unloading stage, the valve is used to control the pipeline on and off, and the delivery pump 1 delivers the suspension to another filter press to make it enter the feeding stage, so that part of the working stages of the two filter presses overlap to improve the overall working efficiency. The setting of two storage tanks can increase the storage capacity of the device, and both storage tanks can provide suspension for a single filter press; when the filter press is suspended, the delivery pump 1 circulates, pumps out the suspension through the first feed pipe 71 and the second feed pipe 81, and returns it to the storage tank through the first circulation pipe 72 and the second circulation pipe 82, so that the suspension is not only stirred under the drive of the stirring device, but also circulates between a single storage tank or two storage tanks under the drive of the delivery pump 1, reducing the possibility of silting.
