[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0019] See also Figure 1 to Figure 3 In the embodiment of the utility model, a novel filter plate of a filter press comprises a filter frame 1 and a filter plate body 2. The filter plate body 2 is arranged on both sides of the filter frame 1, and the filter frame 1 and the filter plate body 2 are fixedly connected by a convenient disassembly component. The disassembly component comprises a mounting frame 11, a spring 12, an L-shaped plate 13 and a fixing plate 14. The middle part of the side wall of the filter frame 1 is welded with a mounting frame 11. The inside of the mounting frame 11 is symmetrically slidably connected with a limiting plate 15. Two springs 12 are fixedly installed between the limiting plates 15. The limiting plates 15 are away from the spring 1. 2, one end of an L-shaped plate 13 is welded to one side of the filter frame 1, and fixing grooves 16 penetrating the filter plate body 2 are provided on both sides of the filter frame 1 close to the L-shaped plate 13, and a placement groove 3 connected to the fixing groove 16 is provided on the side of the filter plate body 2 away from the filter frame 1, and one end of the L-shaped plate 13 away from the limiting plate 15 extends to the outside of the installation frame 11 and is slidably connected to the inside of the placement groove 3, and a fixing plate 14 extending to the inside of the fixing groove 16 is welded to the side of the L-shaped plate 13 close to the fixing groove 16, and a clamping structure is formed between the fixing plate 14 and the fixing groove 16.

[0020] Four mounting frames 11 are provided and are respectively located on the four side walls of the filter frame 1 , and are used to stably fix the filter frame 1 and the filter plate body 2 together.

[0021] When in use, when it is necessary to disassemble the filter plate body 2 and the filter frame 1, the operator holds the opposite L-shaped plates 13 respectively and pulls them toward the side away from each other, so that the limit plate 15 welded thereto moves synchronously. When the limit plate 15 moves, the spring 12 is stretched and deformed. The limit plate 15 is provided to prevent one end of the L-shaped plate 13 from being separated from the mounting frame 11 when the L-shaped plate 13 is pulled. When the L-shaped plate 13 is pulled, the fixing plate 14 welded thereto is gradually separated from the fixing groove 16, thereby releasing the fixing restriction between the filter plate body 2 and the filter frame 1, and then the filter plate body 2 can be removed. Remove and replace. When the replaced filter plate body 2 is to be installed, the filter plate body 2 is sequentially embedded in both sides of the filter frame 1 so that the fixing groove 16 on one side of the filter plate body 2 is aligned one by one with the fixing groove 16 on the side of the filter frame 1. Then, the force applied to the L-shaped plate 13 is released. At this time, the spring 12 is reset and deformed, thereby driving one end of the L-shaped plate 13 to slide toward the inside of the installation frame 11 through the limit plate 15. At this time, the other end of the L-shaped plate 13 drives the fixing plate 14 to slide into the corresponding fixing groove 16, thereby fixing the filter plate body 2 and the filter frame 1 together without the aid of external tools, which is convenient for the operator to use.

[0022] The top and bottom of the filter frame 1 are respectively provided with mounting components for quick installation therebetween, and the mounting components include a scissor frame 21, a positioning block 22 and a nut 23. The top and bottom of the filter frame 1 are respectively provided with a scissor frame 21, and the scissor frame 21 is a scissor structure formed by hinged connection of multiple straight rods. The top and bottom of the filter frame 1 are both provided with a rotating hole 4 located below the hinge of the central axis of the scissor frame 21, and the bottom end of the rotating hole 4 is provided with a limiting hole 5 connected thereto, and the internal rotation connection of the limiting hole 5 is limited. The top surface of the limiting block 24 is welded with a positioning block 22 located inside the rotating hole 4, and the end of the positioning block 22 away from the limiting block 24 passes through the rotating hole 4 and the scissor frame 21 and is threadedly connected with a nut 23 located above the scissor frame 21, and the positioning block 22 is rotatably connected to the rotating hole 4 and the scissor frame 21. The scissor frame 21 is provided with two groups side by side and is respectively located on both sides of the top and bottom of the filter frame 1.

[0023] The limiting hole 5 and the rotating hole 4 are both round holes, the limiting block 24 and the positioning block 22 are both round rods, and the diameters of the limiting hole 5 and the limiting block 24 are respectively larger than the diameters of the rotating hole 4 and the positioning block 22. The setting of the limiting hole 5 and the limiting block 24 cooperates so that the positioning block 22 can only rotate inside the rotating hole 4 and cannot move up and down.

[0024] During use, when installing the filter frames 1, first, the central axis hinge of the corresponding scissor frame 21 is sequentially sleeved on the outer wall of the positioning block 22, and then the nut 23 is rotated and fixed to the thread at the end of the positioning block 22, so that the position of the scissor frame 21 can be restricted and the scissor frame 21 will not be separated from the outer wall of the positioning block 22 during subsequent use. Conversely, when the filter frames 1 are to be disassembled, the nut 23 is rotated down from the end of the positioning block 22 in turn, and the scissor frame 21 can be removed from the outer wall of the positioning block 22, that is, the connection between the filter frames 1 is released, and the operation is simple and quick.

[0025] Working principle: When using the new filter press filter plate, first pull the relative L-shaped plate 13 toward the side away from each other, at this time, the limit plate 15 drives the spring 12 to stretch and deform, and at the same time, the other end of the L-shaped plate 13 drives the fixing plate 14 to disengage from the fixing groove 16, and then the filter plate body 2 is sequentially embedded in both sides of the filter frame 1, so that the fixing groove 16 on one side of the filter plate body 2 is aligned with the fixing groove 16 on the side of the filter frame 1, and then release the force applied to the L-shaped plate 13, the spring 12 is elastically reset, and one end of the L-shaped plate 13 is driven by the limit plate 15 to slide toward the inside of the installation frame 11, and at the same time, the other end of the L-shaped plate 13 drives the fixing plate 14 to slide and insert into the corresponding fixing groove 16. The filter plate body 2 is fixed to the filter frame 1 by the L-shaped plate 13, and the fixing plate 14 is removed from the corresponding fixing groove 16. Then, the L-shaped plate 13 is pulled again in sequence to make the fixing plate 14 disengage from the corresponding fixing groove 16, and the filter plate body 2 is removed from the side of the filter frame 1.
