Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for filter presses, specifically an installation device for a rotary filter cloth cleaning rack. Background Technology

[0002] The filter cloth cleaning rack for filter presses is a specialized device for efficient cleaning of filter cloths. It is usually designed with a frame structure to facilitate rinsing, brushing, or high-pressure water gun cleaning of residual filter residue on the filter cloth. Its main functions are: to support the unfolding of the filter cloth, prevent folding or tangling, ensure thorough cleaning, quickly remove stubborn dirt through spraying, brushing, or soaking, reduce damage to the filter cloth caused by manual cleaning, and avoid tearing or deformation.

[0003] The common problems with the current installation methods of rotary filter cloth cleaning racks used in filter presses are: complex structure, installation requires the cooperation of multiple parts, large space occupation, use of heavy bearing seats or integral fixed structure, resulting in high manufacturing cost, maintenance requires disassembly of the entire mechanism, operation is cumbersome and expensive, and the support frame design is unreasonable, making it impossible to quickly disassemble and assemble the filter cloth cleaning rack.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes an installation device for a rotary filter cloth cleaning rack. Utility Model Content

[0012] At least two sets of bolt holes are symmetrically arranged on both sides of the mounting support frame, and double bolts are used to improve stability.

[0013] In one embodiment of the present invention, the installation steps of the rotary filter cloth cleaning rack are as follows: (1) The lightweight bearing seat and the bearing are pre-installed on the cleaning rack mounting shaft;

[0014] (2) Insert the cleaning rack mounting shaft vertically into the U-shaped mounting hole of the mounting support frame until the bottom of the light bearing seat is embedded in the positioning groove;

[0015] (3) Use two sets of M bolts to pass through the threaded holes on both sides of the mounting support frame to fasten the lightweight bearing housing;

[0016] (4) Check the rotation flexibility of the rotary filter cloth cleaning rack.

[0017] As a further embodiment of this utility model: the lightweight bearing housing is made of split aluminum alloy with a thickness of 25-30mm.

[0018] As a further embodiment of this utility model: at least two sets of bolt holes are symmetrically arranged on both sides of the mounting support frame.

[0019] As a further embodiment of this utility model, a rubber buffer pad is provided on the inner side of the U-shaped mounting hole.

[0020] As a further embodiment of this utility model: the mounting support frame is a split structure, including a bottom fixing plate, a U-shaped bearing section and a top reinforcing beam, and the components are connected by flanges.

[0021] As a further embodiment of this utility model: the surface of the lightweight bearing housing is coated with tungsten carbide, and the mounting support frame is hot-dip galvanized.

[0022] As a further embodiment of this utility model, a guide hole is provided at the bottom of the U-shaped mounting hole.

[0023] As a further improvement of this utility model:

[0024] Compared with the prior art, the beneficial effects of this utility model are: the vertical insertion / extraction of the cleaning rack is achieved through the U-shaped hole, without the need to disassemble the main support frame;

[0025] The use of lightweight bearing housings reduces material costs and installation load. The entire cleaning frame can be removed simply by loosening the bolts, reducing maintenance time by more than 60%. The U-shaped holes and double bolt fixing method reduce the size of the device by 30%.

[0026] By using appropriate materials and effective structures, its corrosion resistance can be improved, thus extending its service life. Attached Figure Description

[0039] The lightweight bearing housing 2 is made of split aluminum alloy with a thickness of 25-30mm;

[0040] At least two sets of bolt holes are symmetrically arranged on both sides of the mounting support frame 5. Stability is improved by fixing with double bolts, and anti-loosening nuts are used for the bolts.

[0041] In one embodiment of the present invention, the installation steps of the rotary filter cloth cleaning rack are as follows: (1) The lightweight bearing seat 2 and the bearing 3 are pre-installed on the cleaning rack mounting shaft 4;
