Description

Technical Field

[0001] This utility model relates to the technical field of needle-punched felt products, specifically an integrated molded quick-installation needle-punched felt. Background Technology

[0002] Needle-punched felt is a nonwoven fabric product made from synthetic fibers (such as polyester, polypropylene, and aramid) or natural fibers through a needle-punching process. Its production process eliminates the need for spinning and weaving; instead, needles on a needle-punching machine repeatedly puncture the fiber web, causing the fibers to entangle and ultimately forming a felt-like material with a certain thickness, strength, and porous structure. This unique forming process endows needle-punched felt with many excellent properties, such as high tensile strength, good abrasion resistance, stable chemical properties, and uniform pore distribution, making it widely used in various fields such as industrial filtration, environmental dust removal, sound and heat insulation, and waterproofing.

[0003] In industrial production scenarios, needle-punched felt, with its outstanding filtration performance, has become one of the core materials for treating pollutants such as dusty gases and industrial wastewater. Manufacturing needle-punched felt into filter cloth cartridges represents an optimized upgrade of the product form to meet actual industrial filtration needs, offering significant application advantages compared to traditional flat-plate needle-punched felt filter elements. Structurally, the filter cloth cartridge features a cylindrical structure open at both ends. This shape maximizes the filtration area of ​​the needle-punched felt; within the same installation space, the effective filtration area of ​​the filter cloth cartridge can reach 3-5 times that of a flat-plate filter element, significantly improving filtration efficiency. This is particularly suitable for industrial scenarios with high dust concentrations and large air volume requirements. Simultaneously, the cylindrical structure allows airflow to be evenly distributed along the inner wall of the cartridge during filtration, avoiding dead zones or filter media wear caused by excessively high local airflow velocities, thus extending the service life of the needle-punched felt. Furthermore, the filter cloth cartridge exhibits stronger structural stability, resisting deformation under high-pressure, high-speed airflow impacts and maintaining a stable pore structure. This ensures that filtration accuracy remains within the ideal range, effectively solving the problems of easy wrinkling and large fluctuations in filtration effect inherent in traditional flat-plate filter elements.

[0004] However, existing filter products made of needle-punched felt materials require workers to attach the needle-punched felt to the mounting frame and then sew the two ends of the needle-punched felt together. This makes the installation process complicated, requires multiple tools and a lot of manual labor, resulting in low installation efficiency and inconvenient disassembly and maintenance, which increases the company's operating costs.
