Technical Field

[0001] The utility model relates to a reinforced combined filter cloth. Background Art

[0002] The filter cloth used in ultra-high pressure filter presses under the working conditions of general coal washing industry is a kind of nylon filter cloth, which has the advantages of high strength, good wear resistance, light weight, good elasticity, and fatigue resistance. However, under ultra-high pressure conditions, the nylon filter cloth with superior comprehensive performance has to be used as a standing consumable and vulnerable part.

[0003] In the prior art, the filter cloth is a piece of hanging cloth placed on both sides of the filter plate. When one side of the filter cloth is damaged, the entire piece has to be removed and replaced, resulting in unnecessary cost increase and waste. In the later use process, it was found that the position of the filter cloth facing the filter plate boss and the weld between the boss and the bottom plate were particularly susceptible to damage.

[0004] Therefore, a reinforced combined filter cloth is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a reinforced combined filter cloth to solve the problem in the above background technology that the filter cloth is easily damaged and the replacement causes waste of resources.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a reinforced combined filter cloth, comprising a fleece filter cloth and a hook filter cloth,

[0007] The upper part of the fleece filter cloth is provided with a Velcro A, and the upper part of the hook filter cloth is provided with a Velcro B.

[0008] The fleece-side filter cloth and the hook-side filter cloth are hung on both sides of the filter plate via Velcro A and Velcro B.

[0009] Preferably, the Velcro A is a fleece-surface Velcro, and the Velcro B is a hook-surface Velcro.

[0010] Preferably, the pile surface filter cloth and the hook surface filter cloth are provided with multiple groups of reinforcement layers, and the reinforcement layers are respectively located at the pile surface filter cloth and the hook surface filter cloth relative to the filter plate chamber surface and the boss weld.

[0011] Preferably, the reinforcement layer comprises non-woven fabric, and polyurethane rubber is sewn on the periphery of the non-woven fabric.

[0012] Preferably, the non-woven fabric is located at the weld between the hook-side filter cloth and the boss, and the polyurethane rubber is located at the surface of the fleece-side filter cloth relative to the filter plate chamber surface.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model provides a fleece filter cloth and a hook filter cloth, which can be replaced independently. When one side of the filter cloth is damaged, there is no need to replace the entire piece, thereby reducing replacement costs and material waste.

[0015] Velcro A and Velcro B are used to facilitate quick disassembly and assembly of the filter cloth, thereby improving ease of use.

[0016] By reducing filter cloth waste, reinforced composite filter cloths help reduce the environmental impact of industrial production. Since filter cloth replacement is more convenient and quick, production interruption time caused by filter cloth replacement is reduced, and production efficiency is improved.

[0017] The reinforced composite filter cloth design reduces the failure rate during use and improves the reliability of the entire filter press system. By reducing the frequency and number of filter cloth changes, the reinforced composite filter cloth helps reduce operating costs and improve economic benefits. The simplified replacement process reduces the complexity and operational risks for maintenance personnel when changing filter cloths.

[0018] The reinforced combined filter cloth design allows for quick replacement of damaged parts, reducing downtime and maintenance workload. The combined design of the filter cloth allows for flexible replacement of corresponding parts according to different usage conditions and damage conditions, enhancing the adaptability of the filter cloth.

[0019] The reinforcement layers provided at the filter plate bosses and welds significantly improve the durability and damage resistance of the filter cloth.

[0020] The reinforcing layer uses polyurethane rubber. When the filter cake suspension enters the cavity of the filter plate, it continuously flows and rubs against the front of the filter cloth. Especially at the boss, the friction is concentrated due to the limited space, and the filter cloth is more easily damaged. Therefore, polyurethane rubber is added to the front of the filter cloth at the boss position to reduce the impact of the friction between the coal slime and the boss on the filter cloth, thereby extending the service life of the filter cloth; enhancing the overall strength and pressure resistance of the filter cloth, which is suitable for the use conditions of ultra-high pressure filter presses.

[0021] For non-woven fabric materials, during the water mold pressing process, when the filter cake is pushed to the side of the material mold, the back of the material mold filter cloth fits tightly with the boss weld. Since the weld cannot make a regular and effective arc transition, it is more likely to cause fatigue damage to the filter cloth in the stress concentration area with large friction under long-term use conditions. Therefore, a wear-resistant non-woven fabric layer is added to the back of the material mold filter cloth to reduce fatigue damage between the filter cloth and the weld, extend the service life of the filter cloth, enhance the durability of the filter cloth in the easily worn area, and extend the service life of the filter cloth.
