[0023] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0024] Embodiment 1

[0025] In this embodiment, a quick-disassembly filter cake structure of a plate and frame filter press is provided, such as Figure 1 and Figure 5 As shown, it includes a top plate 2 installed inside the plate frame 1, the top plate 2 is slidably connected to a sink groove provided on the plate frame 1, and a first spring 3 is installed between the top plate 2 and the inner side surface of the plate frame 1, a fixing block is fixedly connected to the inner side surface of the top plate 2, an empty groove matching the fixing block is provided on the plate frame 1, and a yield groove is provided on the fixing block. One end of the first spring 3 is fixedly connected to the bottom side wall of the yield groove, and the other end is connected to the bottom side wall of the empty groove, so that the top plate 2 can slide more stably. The first spring 3 has a tendency to pull the top plate 2 into the plate frame 1. In the absence of external force, the top plate 2 will be located inside the plate frame 1, so that the material that needs to be squeezed and filtered can be conveniently placed into the plate frame 1. A plurality of rotating rods 13 are hinged on the side of the plate frame 1, and the position of the top plate 2 inside the plate frame 1 can be controlled by controlling the angle of the rotating rod 13, as shown in FIG. Figure 3 As shown, by rotating the rotating rod 13 clockwise, the top plate 2 can be moved to the outside of the plate frame 1.

[0026] A plurality of rotating rods 13 are respectively located at the four corners of the side of the plate frame 1, and rotating rods 13 are provided at both ends of both sides of the plate frame 1. Force can be applied to the top plate 2 from the four corners of the top plate 2 to make the top plate 2 slide more stably. A slide groove 4 is provided on the outside of the rotating rod 13 and located on the plate frame 1. The side of the rotating rod 13 close to the opening of the corresponding plate frame 1 is the outside. A slider 5 is slidably connected inside the slide groove 4. One end of the slider 5 extends to the outside of the slide groove 4. The slider 5 and the top plate 2 are in contact with each other. The rotating rod 13 is rotated in the direction close to the opening of the plate frame 1, so that the rotating rod 13 can push the slider 5 toward the inside of the slide groove 4, thereby enabling the slider 5 to push the top plate 2 toward the opening of the plate frame 1.

[0027] The slider 5 contacts the top plate 2 via the inclined surface provided thereon, and the top plate 2 is provided with an inclined groove adapted to the slider 5 . The arrangement of the inclined surface and the inclined groove enables the slider 5 to better push the top plate 2 toward the opening of the plate frame 1 .

[0028] like Figure 2 As shown, a push rod 7 adapted to the slider 5 is fixedly connected to the side surface of the rotating rod 13 . The arrangement of the push rod 7 enables the rotating rod 13 to better squeeze the slider 5 .

[0029] A driving frame 8 is provided at the four corners of the plate frame 1. The outer end of the rotating rod 13 extends to the interior of the driving frame 8 and is slidably connected to the driving frame 8. The driving frame 8 slides in the direction of the plate frame 1, and the rotating rod 13 can be rotated in the opening direction of the plate frame 1. The angle A between the rotating rod 13 and the plate frame 1 is an acute angle. When the driving frame 8 moves in the direction of the plate frame 1, the rotating rod 13 can stably rotate toward the opening of the plate frame 1. The driving frame 8 is driven by an external cylinder. By controlling the extension and retraction of the external cylinder output rod, it can be controlled whether the driving frame 8 moves in the direction of the plate frame 1.

[0030] The fixed shafts 9 are fixedly connected to both side surfaces of the outer end of the rotating rod 13, and the fixed shafts 9 extend to the inside of the through grooves 10 provided on the driving frame 8. When the plate frame 1 is subjected to extrusion filtering, the rotating rod 13 can move together, and when the driving frame 8 moves toward the direction of the plate frame 1, the rotating rod 13 can rotate smoothly.

[0031] Embodiment 2

[0032] A second spring 6 is connected between one end of the slider 5 located inside the slide groove 4 and the side wall of the bottom of the slide groove 4, and the second spring 6 has an elastic force to push the slider 5 toward the outside of the slide groove 4. The second spring 6 can prevent the slider 5 from slipping out of the slide groove 4. The elastic force of the second spring 6 can prevent the slider 5 from applying a pressing force to the top plate 2 in the absence of external force, thereby keeping the top plate 2 stable.

[0033] Embodiment 3

[0034] like Figure 6 As shown, the rotating rod 13 and the ear plate 11 fixedly connected to the plate frame 1 are hinged to each other, and a third spring 12 is installed between the rotating rod 13 and the ear plate 11. The third spring 12 is a torsion spring, which can keep the rotating rod 13 stable when there is no external force (i.e., Figure 4 The angle shown in the figure) can prevent the rotating rod 13 from rotating at will when the plate frame 1 slides.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
