Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 As shown;

[0026] A filter plate structure of a diaphragm filter press comprises a filter plate 1.

[0027] In this embodiment: the existing disclosure (announcement) number: CN218280676U discloses a filter plate structure of a filter press. In order to solve the existing problems existing in this prior art, as disclosed in the background technology above, "due to the filter plate structure of the diaphragm filter press, the filter plate is easily damaged by a large extrusion force during its squeezing and filtration during use", this problem is obviously a problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a buffer component 2 and a fixing component 3 are added to the present application document.

[0028] More specifically:

[0029] like Figures 1 to 4 As shown:

[0030] In combination with the above content: it also includes a buffer component 2 arranged on the surface of the filter plate 1;

[0031] The buffer assembly 2 includes a base 21 fixedly connected to the two side surfaces of the filter plate 1, a buffer plate 22 is arranged on the surface of the base 21, a push rod 23 is fixedly connected to the side of the buffer plate 22 facing the base 21, a compression groove 25 is opened on the surface of the base 21, the push rod 23 passes through the surface of the base 21 and extends into the compression groove 25, the push rod 23 is arranged at one end of the compression groove 25 and is fixedly connected to a piston 24, the push rod 23 is located at the outer side wall of the buffer plate 22 and is wound with a spring 26, frames 214 are slidably connected to both sides of the filter plate 1, and a mounting plate 215 is fixedly connected to the surface of each frame 214.

[0032] In this embodiment: since the surface of the filter plate 1 is provided with a base 21, the staff can slide the frame 214 to connect the two sides of the filter plate 1, and then install it through the mounting plate 215. When the filter plate 1 receives pressure, it can be buffered by the buffer plate 22. The buffer plate 22 is moved toward the base 21 under pressure and pushes the push rod 23 to move. During this process, the buffer plate 22 squeezes the spring 26, and the spring 26 is squeezed to generate elastic potential energy. At the same time, the push rod 23 drives the piston 24 to move in the compression groove 25. This design can prevent the filter plate 1 from being damaged due to excessive pressure when the device is working.

[0033] It should be noted that the base 21 is formed by splicing, and four bases 21 are symmetrically arranged on the same surface of the filter plate 1 .

[0034] Going further:

[0035] In an optional embodiment, two slide grooves 28 are provided on the surface of each base 21, and a slide rod 29 is arranged in the slide groove 28. The slide rod 29 is rotatably connected to the base 21 through the slide groove 28. The surface of the slide rod 29 is slidably connected to the slider 210. The surfaces of the buffer plate 22 and the slider 210 are fixedly connected to hinge seats 212, and the hinge seats 212 correspond to each other, and a connecting plate 213 is rotatably connected between every two corresponding hinge seats 212.

[0036] In this embodiment: since a slide rod 29 is provided in the slide groove 28, when the buffer plate 22 receives pressure and moves, the buffer plate 22 cooperates with the hinge seat 212 and the connecting plate 213 to make the slider 210 slide with the slide rod 29. With this design, the pressure received by the filter plate 1 can be further reduced.

[0037] Going further:

[0038] In an optional embodiment, a second spring 211 is wound around the surface of each sliding rod 29 , and two ends of the second spring 211 are fixedly connected to the corresponding sliding block 210 and the base 21 , respectively.

[0039] In this embodiment, since the surface of the slide rod 29 is wound with the second spring 211, the second spring 211 is stretched when the slide block 210 moves, so that the second spring 211 generates elastic potential energy. With this design, the pressure on the filter plate 1 can be further buffered.

[0040] It should be noted that the spring 211 is in a stretched state when the buffer plate 22 is subjected to pressure.

[0041] Going further:

[0042] In an optional embodiment, it further includes a fixing component 3 arranged on the surface of the filter plate 1;

[0043] The fixing assembly 3 includes a reinforcing plate 31 slidably connected to both ends of the two frames 214 , and two fixing plates 32 are symmetrically fixedly connected to both sides of the reinforcing plate 31 . The fixing plates 32 are connected to the frames 214 via bolts 33 .

[0044] In this embodiment: since reinforcement plates 31 are provided on both sides of the frame 214, the staff can set the reinforcement plates 31 and the fixing plates 32 at both ends of the frame 214 and connect them through bolts 33. This design can improve the stability of the filter plate 1.

[0045] Working principle: Since the surface of the filter plate 1 is provided with a base 21, the staff can slide the frame 214 to connect the two sides of the filter plate 1, and then install it through the mounting plate 215. When the filter plate 1 receives pressure, it can be buffered by the buffer plate 22. The buffer plate 22 is pressed and moves toward the direction of the base 21 and pushes the push rod 23 to move. In this process, the buffer plate 22 squeezes the spring 26, and the spring 26 is squeezed to generate elastic potential energy. At the same time, the push rod 23 drives the piston 24 to move in the compression groove 25. This design can prevent the filter plate 1 from being damaged due to excessive pressure when the device is working. Since a slide rod 29 is provided in the slide groove 28, when the buffer plate 22 receives pressure, When the pressure is applied and the filter plate 1 moves, the buffer plate 22 cooperates with the hinge seat 212 and the connecting plate 213 to make the slider 210 slide with the slide rod 29. With this design, the pressure received by the filter plate 1 can be further reduced. Since the surface of the slide rod 29 is wrapped with a spring 211, the spring 211 is stretched when the slider 210 moves, so that the spring 211 generates elastic potential energy. With this design, the pressure received by the filter plate 1 can be further buffered. Since reinforcement plates 31 are provided on both sides of the frame 214, the staff can set reinforcement plates 31 and fixing plates 32 at both ends of the frame 214 and connect them with bolts 33. With this design, the stability of the filter plate 1 can be improved.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
