Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection filter bags, in particular to a high-temperature resistant environmental protection filter bag. Background Technique

[0002] The high-temperature resistant environmental protection filter bag is a filtering material specially designed for high-temperature environments and is widely used in the filtration of high-temperature flue gas in industrial fields such as electric power, steel, chemical industry, and cement. It is made of special high-temperature resistant materials such as glass fiber, polyimide, PPS, etc., and can withstand high temperatures of 200°C and above, even higher temperatures, without deformation or melting. The high-temperature resistant environmental protection filter bag not only has excellent high-temperature resistance performance, but also has excellent corrosion resistance and chemical stability, and can be used for a long time in corrosive environments such as acids and alkalis. Its filtration efficiency is high, and it can effectively capture solid particles and impurities in the flue gas, preventing them from damaging equipment and production processes. In addition, the high-temperature resistant environmental protection filter bag also has good mechanical properties and stable performance, can withstand the impact and pressure of high-temperature flue gas, and ensure long-term stable operation.

A protective layer is arranged on the surface of the surface layer. The protective layer includes an antistatic layer. The antistatic layer is arranged on the surface of the surface layer. A high-temperature resistant layer is arranged on the surface of the antistatic layer. A wear-resistant layer is arranged on the surface of the high-temperature resistant layer.

[0004] Although the above scheme enhances the wear resistance of the environmental protection filter bag main body and makes it not easily worn by the impact of dust, in a high-temperature working environment, the overall strength of the environmental protection filter bag is insufficient and it cannot well adapt to such a working environment. At the same time, when the environmental protection filter bag needs to be removed for dust cleaning, the disassembly and assembly of the environmental protection filter bag are inconvenient, affecting the use. Therefore, it does not meet the existing requirements, and for this reason, we propose a high-temperature resistant environmental protection filter bag. Content of the Utility Model

Specific implementation mode

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-6 , the present utility model provides a technical solution: a high-temperature resistant and environmentally friendly filter bag, including a mounting base 1, an annular clamping groove 10 is opened at the lower end of the mounting base 1, and an annular clamping block 11 is arranged inside the annular clamping groove 10;

[0028] It further includes a strengthening layer 5, which is arranged inside the lower end of the annular clamping block 11. A horizontal glass fiber filament 6 is arranged inside the strengthening layer 5, and a plurality of horizontal glass fiber filaments 6 are arranged at equal intervals. A plurality of vertical glass fiber filaments 7 are arranged at equal intervals between the horizontal glass fiber filaments 6. A polyester fiber base layer 4 is arranged on the outer wall of the strengthening layer 5;

[0029] It further includes a moving cavity 9, which is opened at the lower end of the mounting base 1, and four moving cavities 9 are arranged at equal intervals in a ring shape. A moving block 13 is arranged on one side inside each moving cavity 9. A guide rod 12 is adhesively fixed inside each moving cavity 9. The guide rods 12 all penetrate through the moving blocks 13, and the guide rods 12 are all slidably matched with the moving blocks 13. Limiting rods 15 are adhesively fixed to the upper and lower ends inside the moving blocks 13. One end of each limiting rod 15 penetrates through the moving cavity 9 and extends into the annular clamping groove 10.

[0030] During use, the annular clamping block 11 is snapped into the annular slot 10 of the mounting base 1. The elastic force of the return spring 14 pushes the moving block 13 towards the clamping block, driving the limiting rod 15 to insert into the limiting hole 16, achieving quick installation and fixation. When disassembling, the operator slides the moving block 13 through the connecting block 17, compresses the return spring 14, and disengages the limiting rod 15 from the limiting hole 16 to release the fixation. When operating alone, the knob 18 can be rotated to drive the screw rod 19 to rotate in the threaded hole 20, locking the position of the moving block 13, facilitating the operation of other components with both hands without the need for multiple people to assist. The polyphenylene sulfide high-temperature resistant layer 2 and the polyimide flame retardant layer 3 respectively provide high-temperature tolerance and fire protection, while the reinforcing layer 5 is composed of intertwined glass fiber horizontal filaments 6, glass fiber vertical filaments 7, and glass fiber inclined filaments 8, ensuring that the structure remains stable and does not deform at high temperatures, enhancing the overall high-temperature resistance.

[0031] Please refer to Figure 4 , there are two glass fiber inclined filaments 8 arranged between the glass fiber horizontal filaments 6 and the glass fiber vertical filaments 7, and the two glass fiber inclined filaments 8 are cross-connected. The glass fiber inclined filaments 8 and the glass fiber horizontal filaments 6 and the glass fiber vertical filaments 7 form triangles respectively. The triangular structure has extremely high stability, which can significantly improve the overall strength of the reinforcing layer 5, enabling the structure to maintain its shape stability in a high-temperature environment and not easily deform or be damaged;

[0032] Please refer to Figure 2 and Figure 6 , return springs 14 are sleeved outside the guide rods 12. One end of each return spring 14 is connected to the moving cavity 9, and the other end of each return spring 14 is connected to the moving block 13. The return spring 14 can automatically provide a restoring force for the moving block 13, ensuring that during installation or disassembly, the moving block 13 can quickly and stably move to the predetermined position, improving the convenience and efficiency of the operation;

[0033] Please refer to Figure 2 and Figure 5 , one end of each moving block 13 extends to the outside of the moving cavity 9. Connecting blocks 17 are adhesively fixed to the ends of the moving blocks 13 located outside the moving cavity 9. One side inside each connecting block 17 is threadedly connected with a screw rod 19. Two threaded holes 20 are opened on one side of the moving cavity 9, and the threaded holes 20 are threadedly connected with the screw rod 19. By rotating the screw rod 19, the moving block 13 can be fixed without additional tools, the operation is simple and fast, and it can ensure that when operating alone, the moving block 13 will not reset accidentally;

[0034] Please refer to Figure 5 , the lower ends of the screw rods 19 are all equipped with knobs 18. The design of the knobs 18 makes the rotation operation more labor-saving and easy to control, improving the comfort and accuracy of the operation;

[0035] Please refer toFigure 2 and Figure 5 Inside the annular clamping block 11, two limiting holes 16 are respectively opened, and the limiting holes 16 are all adapted to one end of the limiting rod 15 located inside the annular clamping groove 10. Through the cooperation of the limiting rod 15 and the limiting holes 16, the quick and reliable fixation of the annular clamping block 11 is realized, avoiding the problems of falling off or loosening caused by insecure fixation;

[0036] Please refer to Figure 6 , a polyimide flame retardant layer 3 is provided on the outer wall of the polyester fiber base layer 4, and a polyphenylene sulfide high temperature resistant layer 2 is provided on the outer wall of the polyimide flame retardant layer 3. The polyimide flame retardant layer 3 can significantly improve the fire resistance of the material and prevent the spread of fire, while the polyphenylene sulfide high temperature resistant layer 2 can withstand high temperature environments and maintain the stability and durability of the material.

[0037] Working principle: During use, the annular clamping block 11 is clamped into the inside of the annular clamping groove 10. Through the elastic action of the return spring 14, the moving block 13 can move towards the annular clamping block 11, thereby driving the limiting rod 15 to insert into the limiting hole 16 to limit and fix the annular clamping block 11, realizing rapid installation. When removal is required, the operator can hold the connecting block 17 to slide the moving block 13 on the guiding rod 12, causing the moving block 13 to compress the return spring 14. The movement of the moving block 13 will drive the limiting rod 15 to move out of the limiting hole 16, thereby releasing the limit fixation of the annular clamping block 11. When operating alone, the operator can rotate the knob 18, causing the knob 18 to drive the screw rod 19 to rotate, and the screw rod 19 is threadedly connected to the threaded hole 20 on the outside, thereby limiting the moving block 13 and preventing the reset of the moving block 13. The operator can free both hands to move the next moving block 13, thus eliminating the need for multiple people to assist and increasing the practicality. The setting of the polyphenylene sulfide high temperature resistant layer 2 provides an additional protective barrier for the entire structure. It can withstand higher temperatures without performance degradation, further enhancing the durability in high temperature environments. The setting of the polyimide flame retardant layer 3 greatly improves the fire protection level of the material, and the reinforcing layer 5 is composed of glass fiber horizontal filaments 6, glass fiber vertical filaments 7, and glass fiber inclined filaments 8, which can withstand high temperatures without deformation or melting, and can effectively adapt to high temperature working environments.
