Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, and particularly relates to an anti-fracture dust removal filter bag. Background Technique

[0002] The filter bag has excellent chemical stability and heat resistance, is a representative of the highest performance in the filter material industry, and is also the highest-end variety among all commonly used filter materials, reaching a relatively high level in terms of filtration efficiency and filtration accuracy. During the dust removal process, the staff needs to blow the airflow carrying dust onto the filter bag so that the filter bag filters the airflow containing dust.

[0003] During the process of the filter bag filtering the airflow, the filter bag will swing. During the swinging process of the filter bag, its joint part is prone to wear due to friction, which in turn easily causes fatigue and fracture of the woven material on the filter bag, thus easily causing the overall fracture of the filter bag and having a low service life. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an anti-fracture dust removal filter bag.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an anti-fracture dust removal filter bag, including a filter bag body, the filter bag body is woven with blended fibers, a connecting ring is fixed on the bottom surface of the filter bag body, a flange ring is arranged on the bottom surface of the connecting ring, a stabilizing framework is arranged on the upper surface of the flange ring, and a protective layer is arranged on the side wall of the filter bag body.

[0006] By adopting the above technical solutions, when the staff needs to install the dust removal filter bag, the staff needs to connect the protective layer with the filter bag body, sleeved the filter bag body on the stabilizing framework, and connect the connecting ring with the flange ring, then the filter bag body can be kept stable, so that the stabilizing framework always supports the filter bag body, thereby reducing the probability of the filter bag body swinging when filtering gas, thus reducing the probability of continuous friction of the filter bag body, and further reducing the probability of the overall fracture of the filter bag body.

[0007] Further, the stabilizing framework includes a plurality of vertical rods fixedly connected to the upper surface of the flange ring, an annular rod commonly installed on the side walls of the plurality of vertical rods, and a sealing cover commonly installed on the upper ends of the plurality of vertical rods.

[0008] Further, a suction cup is connected to the upper surface of the sealing cover, and a fixed disk is fixed on the inner top wall of the filter bag body.

[0009] By adopting the above technical solution, when the staff sleeved the filter bag body on the stable skeleton, the suction cup and the fixed disk approached and adsorbed each other, so that one end of the filter bag body was always fixed to the sealing cover, thereby further reducing the probability of the filter bag body swinging when filtering gas.

[0010] Furthermore, the protective layer includes a high-temperature resistant layer provided on the side wall of the filter bag body, a stainless steel fiber layer provided on the side wall of the high-temperature resistant layer, and a PU coating provided on the side wall of the stainless steel fiber layer.

[0011] By adopting the above technical solution, stainless steel fiber is a new type of industrial material, which not only has properties such as high conductivity, high thermal conductivity, high strength, high temperature resistance, and corrosion resistance, but also has the characteristics of chemical fiber and synthetic fiber. The stainless steel fiber layer made of stainless steel fiber has good structural strength. The PU coating reduces the probability of wear of the stainless steel fiber layer, thereby reducing the probability of damage to the dust removal filter bag caused by dust substances in the gas when the dust removal filter bag filters the gas.

[0012] Furthermore, the blended fiber includes PTEE fiber, P84 fiber, FG fiber, and PPS fiber that are twisted together.

[0013] Furthermore, the blended fiber also includes NX fiber, and the NX fiber is twisted together with PTEE fiber, P84 fiber, FG fiber, and PPS fiber.

[0014] By adopting the above technical solution, PTEE fiber, namely polytetrafluoroethylene fiber, is a kind of fluorine-containing fiber. Polytetrafluoroethylene fiber has excellent chemical stability, better corrosion resistance than other synthetic fiber varieties, an actual use temperature of 120-180°C, and also has good weather resistance and flex resistance. P84 fiber, namely polyimide fiber, has excellent high temperature resistance, corrosion resistance, and wear resistance. In addition, due to the special cross-sectional structure of P84 fiber, it has a large filtration surface area and excellent filtration performance. FG fiber, namely glass fiber, is an excellent inorganic non-metallic material with a wide variety of types. Its advantages are good insulation, high heat resistance, good corrosion resistance, and high mechanical strength. Polyphenylene sulfide fiber, also known as PPS fiber, has excellent chemical reagent resistance, hydrolysis resistance, and flame retardant properties. NX fiber, namely Metax fiber, has good heat resistance, flame retardancy, and infusibility. The blended fiber composed of PPS fiber, P84 fiber, PTEE fiber, FG fiber, and NX fiber has good heat resistance, wear resistance, and flame retardant properties, which can effectively improve the wear resistance of the dust removal filter bag, thereby further reducing the probability of damage to the dust removal filter bag during filtration.

[0015] Furthermore, a conductive wire is provided at the bag mouth of the filter bag body.

[0016] Further, the suction cup is a suction cup made of silica gel.

[0017] By adopting the above technical solution, silica gel is a highly active adsorption material and belongs to an amorphous substance. Organosilicon can not only withstand high temperatures but also low temperatures, can be used in a very wide temperature range, and both its chemical properties and physical and mechanical properties change very little with temperature. The suction cup made of silica gel has good stability and high-temperature resistance, thereby reducing the probability of the suction cup separating from the fixed plate during normal operation.

[0018] In summary, the present utility model has the following beneficial effects:

[0019] 1. In the present application, when the staff needs to install the dust removal filter bag, the staff needs to connect the protective layer with the filter bag body, sleeved the filter bag body on the stable skeleton, and connect the connecting ring with the flange ring, then the filter bag body can be kept stable, so that the stable skeleton always supports the filter bag body, thereby reducing the probability of the filter bag body swinging when filtering gas, thus reducing the probability of continuous friction of the filter bag body, and further reducing the probability of the overall fracture of the filter bag body;

[0020] 2. In the present application, when the staff sleeved the filter bag body on the stable skeleton, the suction cup and the fixed plate approach and adsorb each other, so that one end of the filter bag body is always fixed with the sealing cover, further reducing the probability of the filter bag body swinging when filtering gas;

Specific implementation manners

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] As Figures 1-5 shown, an anti-fracture dust removal filter bag disclosed in an embodiment of the present application includes a filter bag body 1, a connecting ring 3, a flange ring 31, a stable skeleton 4, a protective layer 5, a suction cup 6, a fixed disk 7, and a conductive wire 8. The connecting ring 3 is a rod-shaped structure with a circular cross-section, and the connecting ring 3 is fixedly connected to the bottom surface of the filter bag body 1, and the flange ring 31 is provided on the bottom surface of the connecting ring 3.

[0030] The filter bag body 1 is woven from a blended fiber 2, and the blended fiber 2 includes PTEE fiber 21, P84 fiber 22, FG fiber 23, PPS fiber 24, and NX fiber 25 that are twisted together.

[0031] The PTEE fiber 21, namely polytetrafluoroethylene fiber, is a kind of fluorine-containing fiber. The polytetrafluoroethylene fiber has excellent chemical stability and better corrosion resistance than other synthetic fiber varieties. The actual service temperature is 120 - 180 °C, and it also has good weather resistance and flexural resistance. The P84 fiber 22, namely polyimide fiber, has excellent high-temperature resistance, corrosion resistance and abrasion resistance. In addition, due to the P84 fiber 22 having a profiled cross-section structure, it has a large filtration surface area and excellent filtration performance. The FG fiber 23, namely glass fiber, is an excellent inorganic non-metallic material with a wide variety. Its advantages are good insulation, high heat resistance, good corrosion resistance and high mechanical strength. The polyphenylene sulfide fiber, also known as PPS fiber 24, has excellent chemical reagent resistance, hydrolysis resistance and flame retardant performance. The NX fiber 25, namely Metas fiber, has good heat resistance, flame retardancy and infusibility. The blended fiber 2 formed by twisting the PPS fiber 24, P84 fiber 22, PTEE fiber 21, FG fiber 23 and NX fiber 25 together has good heat resistance, abrasion resistance and flame retardant performance, which can effectively improve the abrasion resistance of the dust removal filter bag, thereby further reducing the probability of damage to the dust removal filter bag during filtration.

[0032] The stable framework 4 is arranged on the upper surface of the flange ring 31. The stable framework 4 includes a plurality of vertical rods 41, an annular rod 42 and a sealing cover 43. The vertical rods 41 are in a round rod structure, and there are a plurality of vertical rods 41 which are fixedly connected to the upper surface of the flange ring 31. The annular rod 42 is in a rod structure with a circular cross-section, and the annular rods 42 are commonly installed on the side walls of the plurality of vertical rods 41. The sealing cover 43 is in a round sheet structure with an open bottom, and the sealing covers 43 are commonly installed on the upper ends of the plurality of vertical rods 41. The suction cup 6 is connected to the upper surface of the sealing cover 43, and the fixing plate 7 is in a disc structure and is fixed on the inner top wall of the filter bag body 1.

[0033] When the staff sets the filter bag body 1 on the stable framework 4, the suction cup 6 and the fixing plate 7 approach and adsorb each other, so that one end of the filter bag body 1 is always fixedly connected to the sealing cover 43, thereby further reducing the probability of the filter bag body 1 swinging when filtering gas.

[0034] The protective layer 5 is arranged on the side wall of the filter bag body 1. The protective layer 5 includes a high-temperature resistant layer 51, a stainless steel fiber layer 52 and a PU coating 53. The high-temperature resistant layer 51 is arranged on the side wall of the filter bag body 1 and is made of PTEE fiber 21. The stainless steel fiber layer 52 is arranged on the side wall of the high-temperature resistant layer 51, and the PU coating 53 is arranged on the side wall of the stainless steel fiber layer 52.

[0035] Stainless steel fibers are a new type of industrial material, which not only has properties such as high electrical conductivity, high thermal conductivity, high strength, high temperature resistance, and corrosion resistance, but also has the characteristics of chemical fibers and synthetic fibers. The stainless steel fiber layer 52 made of stainless steel fibers has good structural strength. The PU coating 53 reduces the probability of wear of the stainless steel fiber layer 52, thereby reducing the probability that dust substances in the gas damage the dust removal filter bag when the dust removal filter bag filters the gas.

[0036] In order to improve the antistatic ability of the filter bag body 1, a conductive wire 8 is provided at the bag mouth of the filter bag body 1.

[0037] In order to improve the working experience of the staff, the suction cup 6 is made of silica gel. Silica gel is a highly active adsorption material and belongs to the amorphous substance. Organosilicon can not only withstand high temperatures but also low temperatures, can be used in a very wide temperature range, and both its chemical properties and physical and mechanical properties change little with temperature. The suction cup 6 made of silica gel has good stability and high temperature resistance, thereby reducing the probability that the suction cup 6 separates from the fixed disk 7 during normal operation.

[0038] The working principle of an anti-fracture dust removal filter bag in this embodiment is as follows: When the staff needs to install the dust removal filter bag, the staff needs to connect the protective layer 5 with the filter bag body 1, sleeved the filter bag body 1 on the stable skeleton 4, and connect the connecting ring 3 with the flange ring 31, then the filter bag body 1 can be kept stable, so that the stable skeleton 4 always supports the filter bag body 1, thereby reducing the probability that the filter bag body 1 swings when filtering gas, thus reducing the probability of continuous friction of the filter bag body 1, and further reducing the probability that the whole filter bag body 1 breaks.
