[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] In order to solve the technical problem that most of the plate-and-frame filter presses on the market are relatively complex when replacing the filter plate, which is not conducive to the maintenance and repair of the plate-and-frame filter press, as Figures 1-6 shown, the following preferred technical solutions are provided:

[0024] A filter plate of a plate-and-frame filter press that is easy to separate, including a plate frame 1, a filter plate 2 is arranged inside the plate frame 1, a groove 4 is opened at the upper end of the plate frame 1, and symmetrically arranged inflatable rubber pads 5 are provided on the inner walls on both sides of the groove 4. The filter plate 2 can perform reciprocating linear motion in the vertical direction inside the groove 4. Symmetrically arranged moving plates 10 are provided on both sides of the upper end surface of the plate frame 1. The moving plates 10 can perform reciprocating linear motion in the horizontal direction. A pressing plate 14 is provided below one end of the moving plate 10 close to the filter plate 2. A threaded rod 12 is rotatably arranged on the upper end surface of the pressing plate 14. The rotation of the threaded rod 12 drives the pressing plate 14 to perform reciprocating linear motion in the vertical direction. Circular grooves 17 are opened at both ends of the upper end surface of the plate frame 1. Limiting rods 18 are arranged inside the circular grooves 17. The limiting rods 18 can perform reciprocating linear motion in the vertical direction. First limiting holes 15 and second limiting holes 16 adapted to the limiting rods 18 are opened at the upper end of the moving plate 10.

[0025] Specifically, when the worn filter plate 2 needs to be replaced, first manually rotate the threaded rod 12 to drive the pressing plate 14 to move upward to loosen the filter plate 2. Then, the limiting rod 18 moves downward to leave the inside of the first limiting hole 15 to release the limitation on the moving plate 10. Subsequently, pull the moving plate 10 to make it leave above the filter plate 2. After that, the limiting rod 18 moves upward to enter the second limiting hole 16 to fix the position of the moving plate 10. Finally, release the gas in the inflatable rubber pad 5, and the staff takes out the filter plate 2 from the inside of the groove 4. The purpose of this design is to drive the pressing plate 14 to move upward by manually rotating the threaded rod 12 to quickly release the fixation of the filter plate 2. Subsequently, the position of the moving plate 10 is fixed by the limiting rod 18 to prevent it from affecting the operation of the staff when replacing the filter plate 2. Finally, deflate the inflatable rubber pad 5 to reduce the friction force when taking out the filter plate 2 from the inside of the groove 4, so that the staff can quickly take out the filter plate 2 from the inside of the groove 4, completing the replacement and installation of the filter plate 2. Under the action of the overall cooperation, the problem that the filter plate 2 of the existing plate and frame filter press is relatively complicated to disassemble and replace is solved, the labor cost is reduced, and it is beneficial to the maintenance of the plate and frame filter press.

[0026] Further, as Figure 5 shown, the following preferred technical solutions are provided:

[0027] Rubber layers 3 are fixedly attached to the edges of the front and back sides of the filter plate 2. The purpose of this design is to effectively seal the gaps between the plate frames 1 through the rubber layers 3, reducing the probability of leakage during the operation.

[0028] Further, as Figure 1 and Figure 2 shown, the following preferred technical solutions are provided:

[0029] Two symmetrically arranged T-shaped chutes 8 are provided below the moving plate 10. The T-shaped chutes 8 are opened on the upper end surface of the plate frame 1. A T-shaped slider 9 is arranged inside the T-shaped chute 8. The T-shaped slider 9 is fixedly connected to the bottom end surface of the moving plate 10, and the T-shaped slider 9 is slidably connected to the inner wall of the T-shaped chute 8. The purpose of this design is to drive the moving plate 10 to make a reciprocating linear motion in the horizontal direction through the sliding of the T-shaped slider 9 inside the T-shaped chute 8.

[0030] Further, as Figure 1 and Figure 6 shown, the following preferred technical solutions are provided:

[0031] On the upper end surface of the movable plate 10 near one end of the filter plate 2, a threaded hole 11 is provided. The threaded rod 12 is threadedly connected to the threaded hole 11. The lower end of the threaded rod 12 is rotatably connected to the upper end surface of the pressing plate 14 through a bearing. The upper end of the threaded rod 12 is fixedly connected to a turntable 13. The purpose of this design is to drive the rotation of the threaded rod 12 by the rotation of the turntable 13, and the rotation of the threaded rod 12 drives the pressing plate 14 to perform reciprocating linear motion in the vertical direction.

[0032] Further, as Figure 2 and Figure 4 shown, the following preferred technical solutions are provided:

[0033] One end of the spring 19 is fixedly connected to the lower end of the circular groove 17. The end of the spring 19 far from the limiting rod 18 is fixedly connected to the bottom end surface of the circular groove 17. A rectangular hole 20 is provided on the bottom side surface of the circular groove 17. The rectangular hole 20 is communicated with the inside of the circular groove 17. A horizontally arranged moving rod 21 is fixedly connected to the bottom side surface of the limiting rod 18. The end of the moving rod 21 far from the limiting rod 18 passes through the rectangular hole 20 and is fixedly connected to a disc 22. The purpose of this design is to drive the moving rod 21 to move downward in the vertical direction by pressing the disc 22. The moving rod 21 drives the limiting rod 18 to move downward to release the limitation on the movable plate 10. The spring 19 can use its own elastic force to drive the limiting rod 18 to move upward in the vertical direction to restore the limitation on the movable plate 10.

[0034] Further, as Figure 1 and Figure 3 shown, the following preferred technical solutions are provided:

[0035] An air pipe 6 is fixedly communicated with the side surface of the inflatable rubber pad 5. A valve core 7 is fixedly installed at one end of the air pipe 6 far from the inflatable rubber pad 5. The purpose of this design is that the inflatable rubber pad 5 can be inflated through the valve core 7, and the volume of the inflatable rubber pad 5 expands, which can seal the gap between the plate frame 1 and the filter plate 2, improving the sealing effect of the whole device. Moreover, when the filter plate 2 needs to be replaced, the inflatable rubber pad 5 is deflated, reducing the friction encountered when taking out the filter plate 2 from the groove 4.

[0036] Further, as Figure 1 shown, the following preferred technical solutions are provided:

[0037] A handle 23 is fixedly connected to the middle of the upper end of the filter plate 2. The purpose of this design is that the filter plate 2 can be taken out from the groove 4 more easily through the handle 23.

[0038] In summary, when the damaged filter plate 2 needs to be replaced, first, manually rotate the turntable 13 to drive the threaded rod 12 to rotate. The rotation of the threaded rod 12 drives the pressing plate 14 to move upward to loosen the filter plate 2. Then, press down the disc 22 to drive the limiting rod 18 to move downward and leave the inside of the first limiting hole 15, releasing the limitation on the moving plate 10. Subsequently, pull the moving plate 10 to make it leave above the filter plate 2. After that, the limiting rod 18 moves upward under the elastic force of the spring 19 and enters the second limiting hole 16 to fix the position of the moving plate 10. Finally, release the gas in the inflatable rubber pad 5 through the valve core 7, and the staff takes out the filter plate 2 from the inside of the groove 4 through the handle 23. The purpose of this design is to drive the pressing plate 14 to move upward by manually rotating the threaded rod 12, quickly releasing the fixation of the filter plate 2. Subsequently, the position of the moving plate 10 is fixed by the limiting rod 18 to prevent it from affecting the operation of the staff when replacing the filter plate 2. Finally, the inflatable rubber pad 5 is deflated through the valve core 7, reducing the friction when taking out the filter plate 2 from the inside of the groove 4, enabling the staff to quickly take out the filter plate 2 from the inside of the groove 4, completing the replacement and installation of the filter plate 2. Under the overall cooperation, the problem that the replacement of the filter plate 2 in the existing plate and frame filter press is relatively complicated is solved, the labor cost is reduced, and it is beneficial to the maintenance of the plate and frame filter press.
