DETAILED DESCRIPTION

The internal slider 16 and the connecting end block 9 are an integral structure, and a roller 17 is provided in the bottom groove of the internal slider 16. The internal slider 16 is rollingly connected with the limited slide groove 15 through the roller 17;

[0028] The electromagnet plate 18 is embedded in the inner wall of a limiting sliding groove 15 , and a switch 10 is arranged on the outer wall of one side of a horizontal connecting rod 5 .

[0029] When in use, the turntable handle is turned to drive the linkage traction rod to rotate, so that the linkage traction rod drives the pressure push plate to perform a pushing activity, thereby compacting multiple plate frames and bringing multiple plate frames together. At the same time, in order to ensure the stability of the plate and frame filtration process, the switch is pressed so that the power box supplies power to the electromagnet plate. After the electromagnet plate is energized, it generates magnetic force to absorb multiple internal sliders, thereby achieving the purpose of positioning multiple close-fitting plate frames, so that the plate frames always maintain close pressure.

[0030] See also Figure 4 Four filtrate outlets 8 and one injection pipe 21 are arranged on the rear end surface of the thrust plate 2. The four filtrate outlets 8 and one injection pipe 21 are connected to the interior of the plate frame 7. The four filtrate outlets 8 and one injection pipe 21 arranged on the rear end surface of the thrust plate 2 serve to facilitate the discharge of the filtrate and the injection of the filtrate to be filtered.

[0031] See also Figure 4 A valve 22 is provided on the injection pipe 21 , and the valve 22 is sealed and connected to the injection pipe 21 through a flange. The valve 22 provided on the injection pipe 21 plays a role in controlling the opening and closing of the injection pipe 21 .

[0032] See also Figure 3 A hollow circular cavity 19 is provided inside the connecting disk 11, and an anti-slip round head 20 is movably provided inside the hollow circular cavity 19. The anti-slip round head 20 and the linkage traction rod 12 are an integrated structure. The hollow circular cavity 19 provided inside the connecting disk 11 serves to facilitate the internal rotation of the anti-slip round head 20.

[0033] See also Figure 1 Mounting seat plates 3 are arranged on the outer walls on both sides of the end plate 1 and the thrust plate 2. The four mounting seat plates 3 are respectively welded to the outer walls of the end plate 1 and the thrust plate 2. The mounting seat plates 3 arranged on the outer walls on both sides of the end plate 1 and the thrust plate 2 serve to facilitate the grounding installation of the end plate 1 and the thrust plate 2.

[0034] See also Figure 1 and Figure 2The output end of the power box 6 is electrically connected to the input end of the switch 10 , and the output end of the switch 10 is electrically connected to the input end of the electromagnet plate 18 .

[0035] Working principle: When in use, the rotating handle 14 is rotated to drive the linkage traction rod 12 to rotate, so that the linkage traction rod 12 drives the pressure push plate 4 to push, thereby pressing the multiple plate frames 7, so that the multiple plate frames 7 are close together. At the same time, in order to ensure the stability of the plate frames 7 during the filtration process, the switch 10 is pressed, so that the power box 6 supplies power to the electromagnet plate 18. After the electromagnet plate 18 is powered, it generates magnetic force to absorb multiple internal sliders 16, so as to achieve the purpose of positioning the multiple close plate frames 7, so that the plate frames 7 are always close to each other. Finally, the tight pressure is maintained to improve the stability of the plate and frame 7 during the filtration process. The filtrate to be filtered is injected into the interior of the multiple plate frames 7 through the injection pipe 21, and then the valve 22 is closed. Under the action of pressure, the liquid in the material flows out from the filtrate outlet 8 through the filter cloth, while the solid matter is left on the filter cloth. After the filtration is completed, the switch 10 is turned off, and the turntable handle 14 is reversed to release the pushing pressure of the pressure push plate 4. Then the multiple plate frames 7 can be separated, and the solid matter on the filter cloth is washed with clean water to complete the use of the plate and frame filter press.
