Technical Field
[0001] This utility model relates to the field of filter press technology, and in particular to a circulating river silt dewatering filter press. Background Technology
[0002] In river management and ecological maintenance, the treatment of river silt is a crucial task. Silt contains a large amount of water, organic matter, heavy metals and other substances. If it is not effectively treated, it will not only occupy a lot of land resources, but may also cause serious pollution to the surrounding environment, such as causing eutrophication of water bodies and decline in soil quality.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Existing filter press devices usually adopt traditional bolt connections, welding and other methods. Although bolt connections have a certain degree of disassembly, in actual operation, due to the large size of the device and the large number of parts, the installers need to perform a large number of bolt tightening operations in a confined space. This not only results in high labor intensity, but also easily leads to problems such as loose bolts and loose connections, causing liquid leakage and air leakage during the operation of the device, affecting the filter press effect and the service life of the equipment. Utility Model Content

Therefore, we propose a circulating river silt dewatering and filter press device.
[0005] To achieve the above objectives, this application adopts the following technical solution: a circulating river silt dewatering filter press, comprising a filter press body: a connecting column is installed at the front end of the filter press body, an adjusting column is installed at the front end of the connecting column, a control groove is opened inside the adjusting column, a control column is rotatably connected inside the control groove, a connecting pipe is provided inside the control column, arc-shaped blocks are fixedly connected to both ends inside the control groove, adjusting holes are opened at both ends of the control column, a push block is slidably connected inside the adjusting hole, a limiting rod is fixedly connected to the side of the push block near the inside of the adjusting hole, and limiting holes are opened at both ends of the connecting pipe.
[0006] Preferably, guide grooves are provided at both ends of the adjustment hole, and guide blocks are fixedly connected to both ends of the push block, with the surface of the guide block slidingly connected to the interior of the guide groove.
[0007] Preferably, the size of the limiting rod is adapted to the size of the defining hole, and the surface of the limiting rod is inserted into the interior of the defining hole.

[0009] Preferably, the control groove has two annular grooves inside, and two return springs are fixedly connected to the outer diameter surface of the control column, with the surface of the return springs slidingly connected to the inside of the sealing gasket.
[0010] Preferably, a sealing gasket is installed at the rear end inside the control slot.
[0011] Preferably, a return spring is fixedly connected to the rear end of the control slot, and the front end of the return spring is fixedly connected to the rear end of the ring block.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, the operator inserts the connecting pipe into the control column and rotates the connecting pipe, causing the connecting pipe to drive the push block to contact the thicker end of the arc-shaped block.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.
[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: a circulating river silt dewatering filter press device, including a filter press device body 1: a connecting column 2 is installed at the front end of the filter press device body 1, an adjusting column 3 is installed at the front end of the connecting column 2, a control groove 4 is opened inside the adjusting column 3, a control column 5 is rotatably connected inside the control groove 4, a connecting pipe 6 is provided inside the control column 5, arc-shaped blocks 7 are fixedly connected to both ends inside the control groove 4, an adjusting hole 8 is opened at both ends of the control column 5, a push block 9 is slidably connected inside the adjusting hole 8, a limiting rod 10 is fixedly connected to the side of the push block 9 near the inside of the adjusting hole 8, and a limiting hole 18 is opened at both ends of the connecting pipe 6. The operator inserts the connecting pipe 6 into the inside of the control column 5 and rotates the connecting pipe 6, so that the connecting pipe 6 drives the push block 9 to contact the thicker end of the arc-shaped block 7, so that the arc-shaped block 7 pushes the push block 9 to drive the limiting rod 10 to form a limit with the limiting hole 18, thereby achieving the purpose of installing and fastening the connecting pipe 6.
[0023] Reference Figure 4 As shown in this embodiment: guide grooves 11 are provided at both ends of the adjustment hole 8, and guide blocks 12 are fixedly connected to both ends of the push block 9. The surface of the guide block 12 is slidably connected to the inside of the guide groove 11. Through the above arrangement, the push block 9 slides more stably inside the adjustment hole 8, avoiding the push block 9 from shaking during the sliding process, and further improving the stability of the device.
[0024] Reference Figures 2-5 As shown in this embodiment, the size of the limiting rod 10 is adapted to the size of the limiting hole 18, and the surface of the limiting rod 10 is inserted into the interior of the limiting hole 18, so that the limiting rod 10 can be stably inserted into the interior of the limiting hole 18, thereby increasing the stability and robustness of the structure. This design not only makes the overall structure more compact, but also improves the convenience and flexibility of use.
[0025] Reference Figure 4As shown in this embodiment: a return spring 13 is fixedly connected to the side of the push block 9 near the inside of the adjustment hole 8, and the side of the return spring 13 away from the push block 9 is fixedly connected to the inside of the adjustment hole 8. When the operator pushes the push block 9 into the adjustment hole 8, the push block 9 compresses and stores the limiting rod 10, and the limiting rod 10 is inserted into the limiting hole 18. When the operator releases the push block 9, the limiting rod 10 can automatically pop out and release from the limiting hole 18 under the action of compression and storage, further enhancing the convenience of the device.
[0026] Reference Figure 5 As shown in this embodiment: two annular grooves 14 are provided inside the control groove 4. Two return springs 16 are fixedly connected to the outer diameter surface of the control column 5. The surface of the return spring 16 is slidably connected to the inside of the sealing gasket 17. The return spring 16 slides along the direction of the annular grooves 14. This sliding connection allows the control column 5 to be adjusted or positioned to a certain extent inside the control groove 4, improving the flexibility and adaptability of the equipment. The sealing gasket 17 is fixedly connected to the inner wall of the control groove 4, providing a sliding track for the return spring 16, ensuring the smoothness and accuracy of the sliding of the return spring 16.
[0027] Reference Figure 5 As shown in this embodiment, a sealing gasket 17 is installed at the rear end of the control tank 4. By installing the sealing gasket 17 at the rear end of the control tank 4, it is possible to effectively prevent moisture or impurities inside the control tank 4 from seeping into other parts of the device, thus ensuring the sealing and cleanliness of the device.
[0028] Reference Figure 5 As shown in this embodiment: a return spring 16 is fixedly connected to the rear end of the control groove 4. The front end of the return spring 16 is fixedly connected to the rear end of the ring block 15. When the operator rotates the control column 5, the control column 5 drives the ring groove 14 to twist the return spring 16 to store force, and at the same time, it drives the limit between the push block 9 and the arc block 7 to be canceled. When the operator releases the control column 5, under the action of the return spring 16, the control column 5 is quickly reset, and the push block 9 and the arc block 7 are re-established to re-establish contact, and the limiting rod 10 and the limiting hole 18 are re-limited.
[0029] Working Principle: The operator inserts the connecting pipe 6 into the control column 5 and rotates the connecting pipe 6, causing the connecting pipe 6 to drive the push block 9 to contact the thicker end of the arc-shaped block 7. This causes the arc-shaped block 7 to push the push block 9, which in turn drives the limiting rod 10 to form a limit position with the limiting hole 18, thus achieving the purpose of installing and securing the connecting pipe 6. Through the above settings, the push block 9 slides more stably inside the adjusting hole 8, avoiding wobbling during the sliding process and further improving the stability of the device. This allows the limiting rod 10 to be stably inserted into the limiting hole 18, thereby increasing the stability and robustness of the structure. This design not only makes the overall structure more compact but also improves the convenience and flexibility of use. When the operator pushes the push block 9 into the adjusting hole 8, the push block 9 compresses and stores force on the limiting rod 10, causing the limiting rod 10 to be inserted into the limiting hole 18. When the operator releases the push block 9, the limiting rod 10, under the action of compression and storage force, can automatically pop out and disengage from the limiting hole 18. The limitation further enhances the convenience of the device. The return spring 16 slides along the direction of the annular groove 14. This sliding connection allows the control column 5 to be adjusted or positioned to a certain extent inside the control groove 4, improving the flexibility and adaptability of the equipment. The sealing gasket 17 is fixedly connected to the inner wall of the control groove 4, providing a sliding track for the return spring 16 and ensuring the smoothness and accuracy of the return spring 16's sliding. The setting of the sealing gasket 17 installed at the rear end inside the control groove 4 can effectively prevent moisture or impurities inside the control groove 4 from seeping into other parts of the device, ensuring the sealing and cleanliness of the device. When the operator rotates the control column 5, the control column 5 drives the annular groove 14 to twist the return spring 16 to store force, and at the same time, it drives the limit between the push block 9 and the arc block 7 to be canceled. When the operator releases the control column 5, under the action of the rebound force of the return spring 16, the control column 5 is quickly reset, and the push block 9 and the arc block 7 are re-established to re-limit the limiting rod 10 and the limiting hole 18.
[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
