Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, and in particular to a membrane-coated antistatic needle-punched composite felt filter bag. 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 materials, achieving high levels of filtration efficiency and precision. Commonly used filter media include PE, PP, PTFE, PMIA, and NMO.

[0003] Existing filter bags are usually fixedly connected inside the equipment. This installation method is very inconvenient for cleaning the filter bags. After years of use, the filtration function of the filter bags is greatly reduced and the filtration efficiency is low. At the same time, traditional filter bags have relatively low strength and lack the setting of needle-punched composite felt layer and antistatic layer, which makes the filtration effect of the filter bags poor. Utility Model Content

[0004] This utility model discloses a membrane-coated antistatic needle-punched composite felt filter bag, which aims to solve the technical problems of existing filter bags being usually fixedly connected inside the equipment. This installation method is very inconvenient for cleaning the filter bags. After years of use, the filtration function of the filter bags is greatly reduced and the filtration efficiency is low. At the same time, traditional filter bags have relatively low strength and lack the setting of needle-punched composite felt layer and antistatic layer, resulting in poor filtration effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A membrane-coated antistatic needle-punched composite felt filter bag includes a fixing ring plate and a filter bag body. The fixing ring plate has an installation groove on one side, and an equipment box is fixedly connected inside the installation groove. The equipment box contains a detachable installation assembly. A pressure plate is fixedly connected to one side of the equipment box. An upper hanging plate is fixedly connected to the top of the filter bag body, and a lower pressure plate is fixedly connected to the bottom of the filter bag body, with the lower pressure plate in contact with the pressure plate. An antistatic layer is fixedly connected to the outer wall of the filter bag body.

[0007] By incorporating a pressure plate, a fixing component, a long rod, a boss, a short rod, and another fixing component, when a filter bag body is placed between two support components, the long rod slides within the fixing component. This allows the short rod, connected to the boss, to push the two support components, which are rotatably connected to the fixing component, to open or tighten. This causes the two support components to lock the upper hanging plate in place, thus achieving a fixed installation of the filter bag body. Opening the support allows for easy disassembly of the filter bag body for cleaning, improving the practicality and convenience of the device and reducing the difficulty of cleaning the filter bag.

[0008] In a preferred embodiment, the detachable mounting assembly includes a fastener fixedly connected to one side of the equipment housing. The fastener has a circular hole, and a long rod is slidably connected within the circular hole. A boss is fixedly connected to one side of the long rod, and two symmetrical short rods are movably connected to the side of the boss away from the fastener. Grooves are formed on both sides of the fastener, and thin rods are fixedly connected between the top and bottom inner walls of the two grooves. Supports are movably connected to the outside of the two thin rods. Slots are formed on opposite sides of the two support members, and thin shafts are fixedly connected to one side of each slot. The outside of the two thin shafts is movably connected to one end of the short rods.

[0009] In a preferred embodiment, a small hole is provided on one side of the equipment box, and a long rod is slidably connected to the small hole. A rack is fixedly connected to the outside of the long rod, and two short shafts are fixedly connected to the inner walls of both sides of the equipment box at equal intervals. Gear 1 and gear 2 are fixedly connected to the outside of the two short shafts respectively. Gear 1 meshes with rack 1. A transmission roller is fixedly connected to the same side of both gear 1 and gear 2, and a belt is provided between the two transmission rollers.

[0010] In a preferred embodiment, a spring hole is provided on the upper side of the pressure plate, and a spring is fixedly connected in the spring hole. A sliding groove is provided on one side of the equipment box, and a pressure plate is provided in the sliding groove.

[0011] In a preferred embodiment, the bottom of the pressure plate is fixedly connected to the spring, and a rack is fixedly connected to one side of the pressure plate, the rack meshing with a gear.

[0012] The system comprises a housing, a long rod, a rack, a short shaft, a gear, a gear, a transmission roller, a spring, a pressure plate, and a rack. By placing a filter bag on the pressure plate, the pressure plate moves downward, causing the gear meshing with the rack to rotate. The transmission roller, connected by a belt, moves the rack meshing with the gear. The weight of the filter bag itself clamps and secures the filter bag, improving convenience and ensuring a secure fit.

[0013] In a preferred embodiment, a groove is formed on the inner wall of the upper hanging plate, and a needle-punched composite felt layer is slidably connected inside the groove, and a toothed chain is fixedly connected inside the needle-punched composite felt layer.

[0014] In a preferred embodiment, a motor plate is fixedly connected to the top of the upper plate, and a drive motor is fixedly connected to the top of the motor plate. The output shaft of the drive motor is connected to a rotating shaft through a coupling. A rotating gear is fixedly connected to the outer wall of the rotating shaft, and the rotating gear meshes with a gear chain.

[0015] An antistatic layer is placed inside the filter bag's main fabric or between the needle-punched composite felt layer and the membrane layer, and is made by incorporating conductive fibers or using other antistatic materials. This layer effectively prevents the filter bag from generating static electricity during use, improving dust removal efficiency and operational safety. The needle-punched composite felt layer is made of a mixture of various fibers, such as aramid fiber and glass fiber. These fibers have excellent acid and alkali resistance, aging resistance, and high strength, allowing the filter bag to maintain good performance even under harsh working conditions.

[0016] As can be seen from the above, the membrane-coated antistatic needle-punched composite felt filter bag provided by this utility model has the technical effects of improving the ease of filter bag installation, reducing the difficulty of filter bag cleaning, and improving the cleaning effect of filter bag.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The membrane-coated antistatic needle-punched composite felt filter bag disclosed in this utility model is mainly used in existing devices. Existing filter bags are usually fixedly connected inside the equipment. This installation method is very inconvenient for cleaning the filter bags. After years of use, the filtration function of the filter bags is greatly reduced and the filtration efficiency is low. At the same time, traditional filter bags have relatively low strength and lack the setting of needle-punched composite felt layer and antistatic layer, resulting in poor filtration effect.

[0024] Reference Figures 1-4 A membrane-coated antistatic needle-punched composite felt filter bag includes a fixing ring plate 4 and a filter bag body 6. The fixing ring plate 4 has an installation groove on one side, and an equipment box 2 is fixedly connected inside the installation groove. The equipment box 2 has a detachable installation assembly 18 inside. A pressure plate 1 is fixedly connected to one side of the equipment box 2. An upper hanging plate 8 is fixedly connected to the top of the filter bag body 6, and a lower pressure plate 7 is fixedly connected to the bottom of the filter bag body 6. The lower pressure plate 7 is in contact with the pressure plate 1. An antistatic layer 5 is fixedly connected to the outer wall of the filter bag body 6.

[0025] In one specific embodiment, the detachable mounting assembly 18 includes a fixing member 19, which is fixedly connected to one side of the equipment box 2. The fixing member 19 has a circular hole, and a long rod 22 is slidably connected inside the circular hole. A boss 20 is fixedly connected to one side of the long rod 22, and two symmetrical short rods 21 are movably connected to the side of the boss 20 away from the fixing member 19. The fixing member 19 has grooves on both sides, and thin rods are fixedly connected between the top inner wall and the bottom inner wall of the two grooves. Support members 3 are movably connected to the outside of the two thin rods. The two support members 3 have slots on opposite sides, and thin shafts are fixedly connected to one side of the two slots. The outside of the two thin shafts is movably connected to one end of the short rods 21.

[0026] In one specific embodiment, a small hole is provided on one side of the equipment box 2, and a long rod 22 is slidably connected inside the small hole. A rack 23 is fixedly connected to the outside of the long rod 22, and two short shafts 27 are fixedly connected to the inner walls of both sides of the equipment box 2 at equal intervals. Gear 24 and gear 25 are fixedly connected to the outside of the two short shafts 27 respectively. Gear 24 meshes with rack 23. A transmission roller 26 is fixedly connected to the same side of both gear 24 and gear 25, and a belt is provided between the two transmission rollers 26.

[0027] In one specific embodiment, a spring hole 10 is provided on the upper side of the pressure plate 1, and a spring 28 is fixedly connected in the spring hole 10. A sliding groove 11 is provided on one side of the equipment box 2, and a pressure plate 9 is provided in the sliding groove 11.

[0028] In one specific embodiment, the bottom of the pressure plate 9 is fixedly connected to the spring 28, and a rack 29 is fixedly connected to one side of the pressure plate 9. The rack 29 meshes with the gear 25. When the filter bag body 6 is placed between the two support members 3, the long rod 22 slides in the fixing member 19, which can push the short rod 21 connected to the boss 20 to open or tighten the two support members 3 that are rotatably connected to the fixing member 19. This avoids the situation where the filter bag body 6 is not effectively fixed and tilts due to some reason after being placed randomly on the pressure plate 1, thus improving the stability of the filter bag body 6.

[0029] In one specific embodiment, a groove is formed on the inner wall of the upper hanging plate 8, and a needle-punched composite felt layer 12 is slidably connected inside the groove. A toothed chain 17 is fixedly connected inside the needle-punched composite felt layer 12. The spring 28 ensures that when no filter bag body 6 is installed on the pressure plate 9, the spring 28 can cause the rack 29 on the pressure plate 9 to reset the support member 3 connected to the long rod 22, avoiding the need for manual closing of the support member 3 and improving convenience.

[0030] In one specific embodiment, a motor plate 15 is fixedly connected to the top of the upper hanging plate 8, and a drive motor 16 is fixedly connected to the top of the motor plate 15. The output shaft of the drive motor 16 is connected to a rotating shaft 14 through a coupling. A rotating gear 13 is fixedly connected to the outer wall of the rotating shaft 14. The rotating gear 13 meshes with a toothed chain 17. An antistatic layer 5 is disposed inside the base fabric of the filter bag body 6 or between the needle-punched composite felt layer 12 and the membrane layer. It is made by mixing in conductive fibers or using other antistatic materials. This layer can effectively prevent the filter bag from generating static electricity during use, improve dust removal efficiency and safety. The needle-punched composite felt layer 12 is made of a mixture of various fibers, such as aramid fiber and glass fiber. These fibers have excellent acid and alkali resistance, anti-aging properties and high strength, so that the filter bag can still maintain good performance under harsh working conditions.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
