Description

Technical Field

[0001] This utility model relates to the field of dust collector bag technology, specifically a P84 composite anti-corrosion and heat-resistant bag. Background Technology

[0002] P84 filter bags are a flame-retardant, temperature-stable fiber filter media. At a temperature of 240°C, the mechanical properties of P84 polyimide fiber filter media will not change, and the maximum temperature resistance can reach 260°C. P84 fiber filter media has no melting point and is naturally golden in color. P84 polyimide fiber filter media is not a hygroscopic fiber filter media.

[0003] In the existing technology, although P84 fiber has high temperature resistance and corrosion resistance, its smooth surface results in weak dust adhesion and high dust removal energy consumption; although PTFE fiber has excellent chemical stability, its mechanical strength is insufficient, and the filter bag is easy to slip off, affecting its performance, and the replacement of the filter bag is also relatively cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a P84 composite anti-corrosion and heat-resistant cloth bag, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a P84 composite anti-corrosion and heat-resistant cloth bag, comprising an outer frame, an inner frame, and a cloth bag, wherein the cloth bag is located between the outer frame and the inner frame. The outer frame includes a base plate, and L-shaped plates are fixedly connected to all four sides of the base plate. A movable plate is rotatably connected to the middle of the L-shaped plate, and a magnet is fixedly connected to one side of the movable plate. The inner frame includes two U-shaped plates, and an annular plate is fixedly connected to the top of the U-shaped plates. A metal strip is fixedly connected to the surface of the U-shaped plates.

[0006] Preferably, the top and bottom of the movable plate are both fixedly connected to movable rods, and the surface of the movable rods is rotatably connected to the interior of the L-shaped plate.

[0007] Preferably, a fixing rod is fixedly connected to the top of the L-shaped plate, and a through hole adapted to the fixing rod is opened on the top of the bag.

[0008] Preferably, the top end of the fixing rod is rotatably connected to a fixing block, and the top of the annular plate is provided with a through groove that matches the fixing block.

[0009] Preferably, the bag comprises a base fabric layer, a needle-punched layer, and a coating layer.

[0010] Preferably, the base fabric layer is woven from P84 fibers with a warp density of 150 fibers / 10cm and a weft density of 40 fibers / 10cm, and the needle-punched layer is a blend of 50% PTFE fibers and 50% P84 fibers. The coating layer is formed by coating the surface of the needle-punched layer with PTFE emulsion. Beneficial effects

[0011] This utility model provides a P84 composite anti-corrosion and heat-resistant filter bag. Compared with the prior art, it has the following advantages: The P84 composite anti-corrosion and heat-resistant filter bag is positioned between an outer frame and an inner frame. The outer frame includes a base plate, with L-shaped plates fixedly connected to all four sides of the base plate. A movable plate is rotatably connected to the center of the L-shaped plates, and a magnet is fixedly connected to one side of the movable plate. The inner frame includes two U-shaped plates, with an annular plate fixedly connected to the top of the U-shaped plates, and metal strips fixedly connected to the surface of the U-shaped plates. The filter bag is magnetically positioned, directly limiting the filter bag between the outer and inner frames, facilitating the positioning, installation, and replacement of the filter bag. It can effectively position the filter bag. The filter bag is directly fitted onto the fixing rod on the outer frame, which can prevent the filter bag from slipping. The needle-punched layer is made of a blend of 50% PTFE fiber and 50% P84 fiber, which can improve the mechanical strength of the filter bag and increase the adhesion of dust, while reducing the energy consumption for dust removal.
