Description

Technical Field

[0001] This utility model relates to the technical field of rubber compounding filtration and anti-clogging devices, and in particular to a filtration and anti-clogging device for use before cross-linking of rubber compounding. Background Technology

[0002] In elevator systems, rubber wheels play a crucial role, primarily used in guiding, traction, and cushioning components. In the elevator car and counterweight guide rail system, guide rubber wheels ensure the car can move smoothly up and down along the guide rails, reducing vibration and noise and improving passenger comfort. Rubber compound is the main raw material for producing elevator rubber wheels. Rubber compounding and cross-linking is a key step in rubber product manufacturing, directly affecting product performance and quality. Before compounding and cross-linking, rubber raw materials often contain various impurities, such as metal particles, sand, and undispersed rubber lumps. If these impurities are not effectively removed, they will cause defects in rubber products during the cross-linking process, such as bubbles, cracks, and reduced strength, seriously affecting the product's service life and safety.

[0003] Currently, rubber compounding systems on the market mainly consist of a filter main structure and a drive and control system. Early rubber filtration devices mostly used simple filter screen structures with large pore sizes, which could only filter out larger particles of impurities. They could not effectively intercept some micron-sized fine impurities, such as residual catalyst particles and additive agglomerates. These fine impurities, even after rubber cross-linking, still affect the microstructure of rubber products and reduce their physical properties, such as tensile strength and wear resistance. In the production of high-end rubber seals, traditional filtration devices cannot meet the requirement of near-zero tolerance for impurities, resulting in unstable sealing performance of the products. Rubber raw materials are sticky, and during the filtration process, impurities easily adhere to the surface of the filter screen, gradually accumulating and causing filter screen blockage. Once blocked, the filtration efficiency drops significantly, and it may even be necessary to stop the machine to clean the filter screen, seriously affecting the continuity of production. On continuous rubber production lines, frequent shutdowns for cleaning not only waste time and manpower but also cause the rubber raw materials to stay in the equipment for too long, affecting their performance. Moreover, the process of cleaning the filter screen is cumbersome, requiring manual disassembly of the filter screen and cleaning with chemical solvents or high-pressure water guns, increasing production costs and labor intensity. Utility Model Content
