Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of filter bags, specifically a fluorinated filter bag with an antistatic structure. Background Technology
[0002] Filter bags possess excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced type of commonly used filter material, achieving high levels of filtration efficiency and precision. Fluoromex filter bags are highly efficient composite products that are resistant to high temperatures, corrosion, acids and alkalis, and are also resistant to folding and wear.
[0003] A search revealed that a typical example of a filter bag in the prior art is disclosed in CN202654825U, which describes a filter bag comprising a filter bag body, an elastic ring inside the bag opening, and a silicone resin layer on the outside of the filter bag body; the filter bag body is made of woven yarn; and two elastic rings are provided inside the bag opening of the filter bag body. The filter bag of this invention, due to the silicone resin layer on the outside of the filter bag body, has improved surface abrasion resistance, making it less susceptible to damage under the impact of dust and particles, thus extending the service life of the filter bag; at the same time, it reduces the moisture absorption capacity of the filter bag, increasing the filtration effect.
[0004] In summary, existing filter bags are prone to generating static electricity during dust filtration due to friction with dust particles and the effect of airflow. The accumulation of static electricity not only causes dust to adhere to the filter bag surface, making it difficult to detach and reducing filtration efficiency, but it can also potentially generate electrostatic sparks, posing a significant safety hazard in flammable and explosive working environments. Therefore, improvements to existing equipment are necessary to address these issues. Utility Model Content
[0005] The purpose of this invention is to provide a fluoropolymer filter bag with an antistatic structure to solve the problem mentioned in the background art that existing filter bags do not have an antistatic structure when filtering dust, which makes dust easily adsorbed on the surface of the filter bag and difficult to remove, reducing filtration efficiency and potentially causing electrostatic sparks, posing a great safety hazard in some flammable and explosive working environments.

[0007] The filter bag body includes an activated carbon fiber layer, an inner liner, a base layer, a flame-retardant layer, and an antistatic layer. The base layer, flame-retardant layer, and antistatic layer are sequentially arranged between the activated carbon fiber layer and the inner liner. The filter bag body is located in the middle of a support assembly. The support assembly includes a base, support rods, and a top frame. The upper outer side of the base is connected to the lower end of the top frame through multiple equidistant support rods. The upper end of the top frame is fixedly connected to the top of the filter bag body through a snap-fit positioning sleeve. A positioning frame is installed at the lower middle of the snap-fit positioning sleeve, and a bearing is installed in the middle of the positioning frame. A vertical shaft is installed in the middle of the bearing. The vertical shaft is threadedly connected to a limit seat above the bearing, and the bottom of the vertical shaft is connected to the middle of the upper end of a connecting plate. The lower bottom of the connecting plate is detachably connected to the limit block through a transmission rod passing through the base. Cleaning frames are provided on both sides of the vertical shaft, and the two cleaning frames are staggered. The outer sides of the two cleaning frames are attached to the inner wall of the filter bag body.
[0008] Preferably, the bottom of the base is symmetrically provided with dust discharge pipes about the transmission rod, and each of the two dust discharge pipes is provided with a one-way valve, while the top of the two dust discharge pipes is located inside the bottom of the filter bag body.
[0009] Preferably, the top frame is an I-shaped structure, and the upper end of the top frame is penetrated by multiple equidistant connecting bolts that extend to the top of the locking and positioning sleeve. Meanwhile, the locking and positioning sleeve is a T-shaped structure.
[0010] Preferably, a protective cylinder is fitted onto the outer side of the lower end of the top frame and the outer side of the base, and the protective cylinder is made of stainless steel. At the same time, multiple vent holes are equally spaced on the protective cylinder. The upper and lower outer sides of the protective cylinder are connected to the top frame and the base by equally spaced fixing screws.
[0011] Preferably, the inner liner is woven from polyphenylene sulfide fiber, the base layer is woven from stainless steel wire and polyester fiber, and the antistatic layer is needle-punched from a mixture of antistatic fiber and polyester fiber.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the fluorinated filter bag with an antistatic structure,
[0013] To address the problem that existing filter bags lack an anti-static structure, leading to dust adhering to the filter bag surface and being difficult to remove, thus reducing filtration efficiency and potentially causing electrostatic sparks—a significant safety hazard in flammable and explosive working environments—this application incorporates an anti-static layer inside the filter bag body. This gives the filter bag a certain degree of conductivity, allowing dust to be quickly discharged or neutralized through the filter bag's conductive network during use. This effectively avoids the safety hazards of spark discharge and dust explosions caused by static electricity accumulation. Furthermore, the application includes a positioning frame, bearings, a vertical shaft, a limit seat, a cleaning frame, a connecting plate, and a transmission rod, which work together to facilitate the rotation of the vertical shaft. This allows the cleaning frame to remove dust adhering to the inner wall of the filter bag body, improving the anti-static effect and facilitating cleaning. Attached Figure Description

The inner liner 402 is woven from polyphenylene sulfide fiber, which gives the filter bag body 4 excellent thermal and chemical stability during use, and enables it to maintain excellent filtration performance in high-temperature and corrosive environments. The base layer 403 is woven from stainless steel wire and polyester fiber, which gives the filter bag body 4 good corrosion resistance, high temperature resistance, and tensile strength during use. The antistatic layer 405 is needle-punched from a mixture of antistatic fiber and polyester fiber, which gives the filter bag body 4 high filtration accuracy, high filtration efficiency, and good antistatic performance during use.
[0021] according to Figure 1 , Figure 2 and Figure 4 As shown, the filter bag body 4 is located in the middle of the support assembly. The support assembly includes a base 1, support rods 2, and a top frame 3. The upper outer side of the base 1 is connected to the lower end of the top frame 3 through multiple equally spaced support rods 2. The upper end of the top frame 3 is fixedly connected to the top of the filter bag body 4 through a locking positioning sleeve 5. The top frame 3 has an I-shaped structure, and the upper end of the top frame 3 is pierced through the locking positioning sleeve 5 by multiple equally spaced connecting bolts 6, extending above the locking positioning sleeve 5. The locking positioning sleeve 5 has a T-shaped structure. The combination of the top frame 3, locking positioning sleeve 5, and connecting bolts 6 facilitates the fixing of the top of the filter bag body 4 and the installation and fixing of the device. A positioning frame 7 is installed at the lower middle end of the locking positioning sleeve 5. The positioning frame 7 has a bearing 8 in the middle, and a vertical shaft 9 is located in the middle of the bearing 8.
