[0020] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment discloses a filter press extruder, including a tank 1, a cover 2, a pressure plate 3, and a pressing device 4. The upper end face of the tank 1 is provided with an opening. The cover 2 is installed at the upper end opening of the tank 1. A one-way air valve 21 is installed on the cover 2, which can pressurize the tank 1 to increase the internal pressure. An annular plate 11 is provided on the outer periphery of the upper end opening of the tank 1. A sealing ring 5 is installed between the annular plate 11 and the cover 2. The cover 2 can cover the annular plate 11. The pressure plate 3 is annular and is fitted around the tank 1. The pressure plate 3 can slide up and down along the outer wall of the tank 1. The pressure plate 3 is located below the annular plate 11.

[0022] The clamping device 4 is installed on the cover 2. The clamping device 4 includes a first support member 41, a second support member 42, and a threaded rod 43. The threaded rod 43 passes through the first support member 41, and the first support member 41 is threadedly connected to the threaded rod 43. The threaded rod 43 passes through the center of the first support member 41. The rotation of the threaded rod 43 can drive the first support member 41 to move up and down. The first support member 41 includes multiple first connecting plates 411, which extend radially toward the cover 2. The first support member 41 is provided with multiple connecting rods 412. The end of the first connecting plate 411 away from the center of the first support member 41 is fixedly connected to the upper end of the connecting rod 412. The connecting rod 412 passes through the cover 2 and the ring plate 11 and is connected to the pressure plate 3. The connection rod 412 and the pressure plate 3 are detachable. The connection consists of multiple connecting rods 412 arranged in a ring. The lower end of the connecting rod 412 passes through the lower end of the pressure plate 3. The lower end of the connecting rod 412 is provided with two stops 4121. The stops 4121 abut against the lower end face of the pressure plate 3. A deformation groove 4122 is opened between the two stops 4121, allowing the two stops 4121 to deform elastically. When the lower end of the connecting rod 412 is inserted into the pressure plate 3, the two stops 4121 can move closer to each other and deform until the stops 4121 pass through the pressure plate 3. Then the two stops 4121 move away from each other. The upper end of the stops 4121 can abut against the pressure plate 3 when the connecting rod 412 moves upward, so that the pressure plate 3 abuts against the lower end face of the ring plate 11. The outer surfaces of the two stops 4121 are arc surfaces, allowing the two stops 4121 to pass through the pressure plate 3 more effectively.

[0023] The upper end face of the second support member 42 is provided with a connecting seat 423. At least a portion of the lower end of the threaded rod 43 is located inside the connecting seat 423. The lower end of the threaded rod 43 is connected to the connecting seat 423 through a bearing. The lower end of the threaded rod 43 is rotatably connected to the second support member 42. The threaded rod 43 can rotate on its own at the center of the second support member 42. The upper end of the threaded rod 43 is provided with a handle 431, which makes it easier to rotate the threaded rod 43. The lower end face of the second support member 42 abuts against the upper end face of the cover 2. The rotation of the threaded rod 43 can drive the pressure plate 3 to approach the ring plate 11.

[0024] More preferably, the second support member 42 includes a plurality of second connecting plates 421 extending radially toward the cover 2. The second connecting plates 421 are arranged in a ring. The upper end face of the cover 2 is provided with a positioning block 22. The lower end face of the second connecting plates 421 is provided with a positioning groove 422 corresponding to the positioning block 22. When the second support member 42 is installed, the positioning groove 422 of each second connecting plate 421 is inserted into the positioning block 22 on the upper end face of the cover 2, which can limit the rotation direction of the second support member 42. The upper end face of the cover 2 is provided with a support block 23. The upper end face of the support block 23 is provided with a groove 231. The lower end face of the second support member 42 is provided with a protrusion 424. The protrusion 424 is at least partially located in the groove 231, which can be positioned when the second support member 42 is installed, and at the same time, the force between the second support member 42 and the cover 2 is more even.

[0025] There are three first connecting plates 411 and three second connecting plates 421. One second connecting plate 421 is located between two adjacent first connecting plates 411. The first connecting plates 411 and the second connecting plates 421 are arranged in a ring-shaped interval in the horizontal direction. The connecting rod 412 and the second support member 42 are arranged in a ring-shaped interval, which can apply force evenly between the pressure plate 3 and the cover 2, so that the force applied by the cover 2 and the ring plate 11 against the sealing ring 5 is more even, and the sealing effect between the cover 2 and the tank body 1 is better.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
