Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a leak-proof sealed filter press. Background Technology

[0002] A filter press is a device for separating solid-liquid mixtures. It is also an effective dewatering device. Chinese patent document with publication number CN108786201B discloses a plate for a filter press, a filter press, the uses of a filter press, and a method for cleaning a filter press.

[0003] However, the inlet and outlet pipes of the filter press using the above-mentioned technical solution often fail to seal, causing the filtered liquid to leak through the connection points. Moreover, after solid-liquid separation, the solids will fall directly from the filter plate onto the ground, requiring workers to handle them afterward. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as sealing failure, easy leakage, and the separation of solids without a catch, resulting in them falling directly to the ground. This invention proposes a leak-proof sealed filter press.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The left end of the sealing and fixing sleeve is connected to the connecting pipe on the right side of the filter press body. The sealing and fixing sleeve is connected to the threaded connector. The inner side of the sealing sleeve is fitted onto the surface of the sealing and fixing sleeve. The inner side of the connecting sleeve is fitted onto the surface of the threaded connector. The sealing ring is located inside the sealing sleeve.

Then, a secondary sealing is achieved by using the cooperation of the sealing sleeve, connecting sleeve, and sealing ring, which provides better leak prevention and sealing. In addition, the receiving hopper can collect solids that fall from the filter press body, and the solids on the receiving hopper can be easily discharged through adjustment.

[0014] In a preferred embodiment of this utility model, the adjusting mechanism includes an electric push cylinder, a hinge rod, a drive wheel, and a transmission belt. The output end of the electric push cylinder is hinged to one end of the hinge rod, and the other end of the hinge rod is hinged to the left side of the drive wheel.

The connection method of the sealing and fixing sleeve and the threaded connector facilitates installation and disassembly and can also achieve a better sealing effect. The limiting ring is mainly for the sealing sleeve and the connecting sleeve to fix the sealing and fixing sleeve and the threaded connector.

[0017] As a preferred embodiment of this utility model, a sealing gasket is bonded to the side of the limiting ring, with two corresponding sealing gaskets, which can achieve a better sealing effect.

[0018] As a preferred embodiment of this utility model, the surfaces of the sealing sleeve and the connecting sleeve are provided with anti-slip textures, and the two limiting rings are located on the inner sides of the sealing sleeve and the connecting sleeve respectively.
