Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion structure technology, and in particular to a high-efficiency extrusion structure for filter presses. Background Technology
[0002] As an important solid-liquid separation device, the filter press is widely used in chemical, pharmaceutical, food, and mining industries. It is mainly used to separate solid particles from liquid in suspension. One of the core components of a traditional filter press is the extrusion structure, which is responsible for applying pressure to force the liquid through the filter medium, leaving solid residue.
[0003] According to the published patent CN217252452U, this utility model relates to the field of filter press technology, specifically disclosing an adjustable pressure roller structure for a belt filter press. It includes a belt filter press and two pressure rollers (number two and number one) located at the upper and lower ends inside the belt filter press. Both the number two and number one pressure rollers are fitted with a filter belt that can move and compress the sludge. Side grooves are provided on the upper ends of the left and right sides of the inner wall of the belt filter press. An internal groove is provided on the side of the inner wall of each of the two side grooves that are far apart from each other. The design of the adjusting threaded rod allows for adjustment of the distance between the number two and number one pressure rollers, thus facilitating a good compression filtration effect for sludge with high water content. Furthermore, the arrangement of two number one motors and two adjusting threaded rods allows the left and right ends of the number two pressure roller to move simultaneously in the same direction, preventing the number two pressure roller from tilting and affecting the normal operation of the belt filter press. However, the following problems still exist:
[0004] Although the distance between the two pressure rollers can be changed by adjusting the threaded rod, it is not easy to adjust to the optimal state when processing sludge with different densities and viscosities. Frequent adjustment of the pressure roller spacing may lead to excessive wear of the threaded part, increasing maintenance frequency and cost. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a high-efficiency extrusion structure for filter presses.
[0006] This utility model is achieved by the following technical solution: a high-efficiency extrusion structure for a filter press, including an extrusion mechanism, with protective mechanisms provided on both sides of the extrusion mechanism, and a main body mechanism provided at the bottom of the protective mechanism;

[0008] As a further improvement to the above solution, a connecting plate is fixedly connected to the side of the protective ring away from the first extrusion shaft, and bolts are bolted to one side of the connecting plate. There are four first extrusion rods and four second extrusion rods.
[0009] The above technical solution, by setting a first extrusion shaft and a second extrusion shaft, and cooperating with a first extrusion ring and a second extrusion ring, enhances the strength of the structure, effectively disperses pressure, and avoids damage caused by excessive single-point load, thereby affecting the normal operation of the device.
[0010] As a further improvement to the above solution, the protective mechanism includes a first protective block, a second protective block is sleeved on one side of the first protective block, and a first connecting block and a second connecting block are respectively fixedly connected to the top of the first protective block and the second protective block.
[0011] As a further improvement to the above solution, a first protective rod is fixedly connected to one side of the first connecting block, and a second protective rod is sleeved on the side of the first protective rod away from the first connecting block.
[0012] The above technical solution, through the protective mechanism, and through the first and second protective blocks, significantly improves the protective effect of the equipment and reduces safety hazards during operation. The sleeve connection of the first and second extrusion rods and the bolted connection plate provide flexibility in pressure adjustment, making it easy to adjust in a timely manner according to the characteristics of different materials, and also facilitating daily maintenance and parts replacement.
[0013] As a further improvement to the above solution, the main structure includes a base plate, a side plate fixedly connected to the top of the base plate, a support column fixedly connected to the bottom of the base plate, and a pad fixedly connected to the bottom of the support column.
[0014] As a further improvement to the above solution, a limiting rod is fixedly connected to the side of the filter plate near the second extrusion shaft. A filter plate is sleeved on the surface of the limiting rod, and an extrusion plate is fixedly connected to the side of the filter plate near the second extrusion shaft.

[0015] As a further improvement to the above solution, a stabilizing plate is fixedly connected to the side of the side plate away from the filter plate, a nozzle is fixedly connected to the bottom of the stabilizing plate, and a motor is fixedly connected to the side of the side plate away from the nozzle.
[0016] The above technical solution, through the stable frame formed by the base plate, side plates and support columns, combined with the limiting rod and filter plate, forms a high-efficiency filtration channel, optimizes the material flow path, improves filtration efficiency, reduces moisture residue through efficient extrusion and filtration of materials, facilitates raw material recycling and reuse, and thus improves the working efficiency of the device.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention enhances structural strength and effectively disperses pressure by setting a first extrusion shaft and a second extrusion shaft, along with a first extrusion ring and a second extrusion ring. This prevents damage caused by excessive single-point load, thus affecting the normal operation of the device. The protective mechanism, consisting of a first protective block and a second protective block, significantly improves the protective effect of the equipment and reduces safety hazards during operation. The sleeve connection of the first and second extrusion rods and the bolted connecting plate provide flexibility in pressure adjustment, facilitating timely adjustments based on different material characteristics.
