The pull plate trolley is installed on the guide rails on both sides of the main beam of the filter press. Its working principle is to drive the transmission chain by a hydraulic motor to drive the mechanical hand to move. However, when the pull plate trolley moves, the filter plates need to be moved to the other side of the main beam and then returned to pull the filter plates that are stuck together. This process is repeated to pull the filter plates one by one, which is inefficient. SUMMARY

Roller group is connected with sliding frame 2, and conveyor belt 8 is sleeved on roller group, and roller group is always tight conveyor belt 8. Adjusting assembly is used to adjust the length of the uppermost horizontal section of conveyor belt 8, and the length of the uppermost horizontal section is adjusted in time according to the distance that filter plate 14 needs to move. The side of filter plate 14 is fixedly provided with contact rod 15, and contact rod 15 is rectangular column. Contact block 7 for abutting with the side of contact rod 15 is arranged on conveyor belt 8 at intervals. The controller, first motor 16 and adjusting assembly are electrically connected.

[0017] As preferred, the roller group includes first roller 3, second roller 4, third roller 11, fourth roller 5, fifth roller 6 and second motor 12, the first roller 3, second roller 4, third roller 11, fourth roller 5 and fifth roller 6 are axially horizontally arranged and rotationally connected with the sliding frame 2, the circulating track of the conveyor belt 8 is a U-shaped structure, and the opening of the U-shaped structure is parallel to the arrangement direction of the filter plate 14. The first roller 3, second roller 4, third roller 11, fourth roller 5 and fifth roller 6 are rotationally arranged at the turning points of the U-shaped structure. The second motor 12 is fixedly connected with the sliding frame 2 and drives one of the rollers away from the opening position of the U-shaped structure to rotate. In this embodiment, the first motor 16 and the second motor 12 are both hydraulic motors.

[0018] As preferred, the first roller 3 and the second roller 4 are located at both sides of the opening of the U-shaped structure, and the first roller 3 and the second roller 4 are horizontally slidably connected with the sliding frame 2. When the first roller 3 moves horizontally, the length of the uppermost horizontal section of the conveying belt 8 changes. The first roller 3 and the second roller 4 move reversely, so that the conveying belt 8 is always in a taut state.

[0019] As preferred, the adjusting assembly comprises two sliding blocks 9 and two third motors 10. The sliding blocks 9 are horizontally slidably connected with the sliding frame 2, the first roller 3 and the second roller 4 are rotatably connected with the two sliding blocks 9 respectively, and the third motors 10 are fixedly connected with the sliding blocks 9 and used for driving the first roller 3 and the second roller 4 to rotate. The two third motors 10 are electrically connected with the controller. The output shafts of the two third motors 10 are provided with second gears respectively, and the sliding frame 2 is provided with two second strip gears in the same sliding direction of the first roller 3 and the second roller 4. The second gears are engaged with the second strip gears, so that the sliding blocks 9 can slide horizontally, thereby driving the first roller 3 and the second roller 4 to move reversely synchronously.

[0020] As preferred, the side edges of the conveying belt 8 are provided with chains, the first roller 3, the second roller 4, the fourth roller 5 and the fifth roller 6 are provided with sprockets, the chains are matched with the sprockets, the sprocket transmission makes the conveying belt 8 not slip and can bear greater load. The third roller 11 at the bottom of the U-shaped structure is a circular cylinder. When the conveying belt 8 moves to the third gear, the contact block 7 on the conveying belt 8 contacts with the outer surface of the third roller 11. The circular cylinder avoids the situation that the contact block 7 is pressed against the third roller 11, thereby affecting the rotation of the conveying belt 8.

[0021] As preferred, the sliding frame 2, the conveying belt 8, the roller set, the first motor 16 and the adjusting assembly are symmetrically arranged at both sides of the support frame 1, the contact rods 15 on one side of the filter plate 14 are arranged at intervals, and the contact rods 15 on the other side of the filter plate 14 are correspondingly staggered. When the gap between the adjacent two contact rods 15 of the filter plate 14 is too small, it may affect the upward movement of the contact block 7 to the side surface of the contact rod 15 when the conveying belt 8 passes the position of the first roller 3. The staggered arrangement of the contact rods 15 can increase the distance between the two contact rods 15.

[0022] Work steps: after the plate and frame filter press completes the filtration, the end of the sliding frame 2 away from the filter plate 14 corresponds to the tail of the slide rail on the support frame 1, the second motor 12 drives the fifth roller 6 to rotate, the conveyor belt 8 is conveniently circulated, the third motor 10 located above drives the first roller 3 to gradually approach several filter plates 14 that are pasted together, and when the other third motor 10 drives the second roller 4 to move in the opposite direction, the conveyor belt 8 is taut. When the conveyor belt 8 passes through the first roller 3, the contact block 7 on the conveyor belt 8 moves from the lower direction to the side of the contact rod 15, and the continuously rotating conveyor belt 8 will drive the filter plate 14 to move, so as to be separated from the adjacent filter plate 14, and then the third motor 10 makes the first roller 3 continue to move close to the next filter plate 14, and the contact block 7 on the conveyor belt 8 separates the filter plate 14 quickly one by one. At the same time, the first motor 16 drives the sliding frame 2 to move, so that the contact block 7 moves downward through the fourth roller 5 before the contact block 7 pushes the filter plate 14 to contact the previously moved filter plate 14, so as to avoid the contact block 7 pushing the filter plate 14 to move and the previously separated filter plate 14.

[0023] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application.
