Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a filter cloth cleaning anti-collision guide structure. Background Technology

[0002] In the filter cloth cleaning process of a filter press, traditional cleaning devices use a rigid structure to drive a nozzle frame to clean multiple filter plates and filter cloths from top to bottom. Due to filter plate positional deviations, equipment vibration, and long-term wear, the following problems are likely to occur:

[0003] Impact damage: Rigid contact between the cleaning frame and the filter plate can cause frame deformation or scratches on the filter plate surface;

[0004] Unstable guidance: The cleaning nozzle's movement trajectory deviates, reducing the cleaning effect;

[0005] High maintenance costs: The metal guide components need to be replaced as a whole after they wear out, which is time-consuming and costly.

[0006] While existing technologies have attempted to improve the situation by increasing the processing accuracy of equipment or adding sensor control, they suffer from problems such as complex structure, high cost, and poor adaptability.

[0007] To address this issue, this technical solution designs an anti-collision guide structure for filter cloth cleaning, which solves the aforementioned problems. Utility Model Content

[0008] The purpose of this invention is to provide a filter cloth cleaning anti-collision guide structure to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A filter cloth cleaning anti-collision guide structure includes: a cleaning frame on which a spray pipe assembly for spraying the filter cloth is installed; guide supports are symmetrically installed on both sides of the cleaning frame, and plastic anti-collision guide blocks are detachably installed at the bottom of the guide supports. The working surface of the guide supports is provided with an inverted triangular guide structure and is embedded with metal reinforcing ribs. An elastic buffer layer with a thickness of 3-10mm is provided between the guide supports and the plastic anti-collision guide blocks. The elastic buffer layer is made of rubber or polyurethane material.

[0011] As a further embodiment of this utility model: the inverted triangular guide structure has an inclination angle of 30°-60°, and its surface is covered with a wear-resistant coating.

[0012] As a further embodiment of this utility model: the plastic anti-collision guide block is made of ultra-high molecular weight polyethylene or nylon composite material;

[0013] As a further embodiment of this utility model, a drainage groove is provided on the upper side of the guide support to prevent the accumulation of cleaning fluid and subsequent corrosion.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by absorbing impact energy through plastic guide blocks, the collision damage between the frame and the filter plate is reduced;

[0015] The inverted triangular structure guides the nozzle to move along a predetermined trajectory, improving the uniformity of cleaning.

[0016] Modular design allows for individual replacement of worn guide blocks, reducing downtime.

[0017] By using non-metallic materials to adapt to humid working conditions, the service life is extended;

[0018] Compared to metal structures, overall maintenance costs are reduced by more than 40%. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please see Figures 1-3 A filter cloth cleaning anti-collision guide structure includes: a cleaning frame 1, on which a spray pipe assembly for spraying the filter cloth is installed; guide supports 2 are symmetrically installed on both sides of the cleaning frame 1, and plastic anti-collision guide blocks 3 are detachably installed at the bottom of the guide supports 2, with an inverted triangular guide structure 4 on its working surface and metal reinforcing ribs 5 embedded inside; an elastic buffer layer 6 with a thickness of 3-10mm is provided between the guide supports 2 and the plastic anti-collision guide blocks 3, and the elastic buffer layer 6 is made of rubber or polyurethane material;

[0028] In this embodiment of the invention, the inverted triangular guide structure 4 has an inclination angle of 30°-60°, and its surface is covered with a wear-resistant coating.

[0029] Plastic anti-collision guide block 3 is made of ultra-high molecular weight polyethylene or nylon composite material;

[0030] A drainage groove 7 is provided on the upper side of the guide support 2 to prevent the accumulation of cleaning fluid and corrosion.

[0031] In one embodiment of the invention, guide supports 2 are welded to both sides of the cleaning frame 1. Each guide support 2 is fixedly mounted with a plastic anti-collision guide block 3 by bolts. The working surface of the plastic anti-collision guide block 3 is machined with an inverted triangular guide structure 4 with an inclination angle of 45°, and stainless steel metal reinforcing ribs 5 are pre-embedded inside. The surface is sprayed with a tungsten carbide wear-resistant coating. A 5mm thick polyurethane elastic buffer layer 6 is set between the guide support 2 and the guide block 3. During the cleaning process, when the nozzle assembly moves up and down, the inverted triangular guide structure 4 automatically corrects the offset, the elastic buffer layer 6 absorbs vibration energy, and the drainage tank 7 discharges residual cleaning fluid.

The surface is coated with a ceramic wear-resistant coating. A spring shock absorber (not shown) is added between the guide support 2 and the cleaning frame 1 to further reduce the impact of high-frequency vibration on the guiding accuracy. The elastic buffer layer 6 is made of oil-resistant rubber with a thickness of 8mm, which is suitable for cleaning environments containing oil.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
