Description

Technical Field

[0001] This utility model relates to the field of dust collector filter element technology, and in particular to an antistatic dust collector filter element. Background Technology

[0002] Dust collector filter elements are key components of dust collectors, primarily used to filter dust particles from dust-laden gas, allowing the purified gas to be released into the atmosphere to meet environmental protection and production process requirements. They typically consist of a filter layer, a support layer, and seals. The filter layer is the core component, used to intercept dust; the support layer supports the filter layer, maintaining its shape and withstanding pressure; and the seals ensure a tight seal between the filter element and the dust collector, preventing leakage of dust-laden gas.

[0003] In the existing technology, during the filtration process of dust collector filter elements, dust particles move at high speed and rub against the surface of the filter element, generating static electricity. If the static electricity cannot be guided out in time, it will accumulate and cause more dust to be adsorbed, affecting the filtration efficiency. At the same time, it can also cause sparks, which will pose a safety hazard. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where, during the filtration process of dust collector filter elements, dust particles move at high speed and rub against the filter element surface, generating static electricity. If the static electricity cannot be guided out in time, it will accumulate, causing more dust to be adsorbed, affecting filtration efficiency, and at the same time, it will cause sparks, posing a safety hazard. Therefore, an anti-static dust collector filter element is proposed.

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

[0006] An antistatic dust collector filter element includes a connecting ring, a filter element cylinder, and a support ring. The connecting ring is fixedly connected to the top of the filter element cylinder, and the support ring is fixedly connected to the bottom of the filter element cylinder. A positioning insert ring is fixedly connected to the bottom of the support ring. The filter element cylinder wall is wrapped with anti-dust and anti-static cotton. Multiple metal conductive strips are wrapped around the side wall of the anti-dust and anti-static cotton. Two clamps are simultaneously fastened to the side wall of the multiple metal conductive strips.

[0007] Preferably, a first sealing rubber ring is fixedly connected to the side wall of the positioning ring, and a second sealing rubber ring is fixedly connected to the top end of the connecting ring.

[0008] Preferably, a metal collar is fixedly fitted on the side wall of the clamp mentioned above.

[0009] Preferably, a plurality of conductive brushes are fixedly connected around the side wall of the metal collar, and the plurality of conductive brushes respectively penetrate the metal collar and are in contact with the metal conductive strip.

[0010] Preferably, the sidewall of the connecting ring is provided with a plurality of mounting slots, and the inner walls of the plurality of mounting slots are respectively set as arc surfaces.

[0011] Preferably, the inner walls of the plurality of mounting slots are respectively fixedly connected with a plurality of anti-slip silicone strips.

[0012] Compared with the prior art, this utility model provides an antistatic dust collector filter element, which has the following beneficial effects:

[0013] 1. This antistatic dust collector filter element generates static electricity through friction between the antistatic cotton and dust in the gas. The metal conductive strips are tightly attached to the side wall of the antistatic cotton to conduct the generated static electricity away. Two clamps are fastened to multiple metal conductive strips to ensure close contact between the metal conductive strips and the antistatic cotton, improving the static electricity conduction efficiency. Multiple conductive brushes on the metal ring on the side wall of the upper clamp contact the metal conductive strips, further enhancing the static electricity conduction path and conducting the static electricity to the outside, preventing static electricity accumulation from affecting the filter element's filtration performance and the safe operation of the equipment.

[0014] 2. The antistatic dust collector filter element uses a first sealing rubber ring on the side wall of the positioning insert ring and a second sealing rubber ring on the top of the connecting ring to achieve a sealing effect. When the filter element is installed in the equipment, the first sealing rubber ring fits tightly with the corresponding part of the equipment to prevent dust-laden gas from leaking from the bottom of the filter element; the second sealing rubber ring seals with the upper connection part of the equipment to ensure that gas can only be filtered through the filter element cylinder, thereby improving the filtration efficiency of the filter element and the sealing performance of the equipment.

[0015] 3. This antistatic dust collector filter element is used to connect with other equipment through multiple mounting slots on the side wall of the connecting ring. During installation, the connecting parts of other equipment are inserted into the mounting slots. The arc design of the mounting slots facilitates the insertion and fixation of the connecting parts. Multiple anti-slip silicone strips are fixed on the inner wall of the mounting slots to increase the stability of the connection and prevent the connecting parts from loosening.

Detailed Implementation

[0020] 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.

[0021] Reference Figure 1-3 An antistatic dust collector filter element includes a connecting ring 1, a filter element cylinder 2, and a support ring 3. The connecting ring 1 is fixedly connected to the top of the filter element cylinder 2, and the support ring 3 is fixedly connected to the bottom of the filter element cylinder 2. A positioning insert ring 4 is fixedly connected to the bottom of the support ring 3. The cylinder wall of the filter element cylinder 2 is wrapped with anti-dust and anti-static cotton 7. Multiple metal conductive strips 8 are attached and fitted around the side wall of the anti-dust and anti-static cotton 7. Two clamps 9 are simultaneously clamped and fitted on the side wall of the multiple metal conductive strips 8.

[0022] A first sealing rubber ring 5 is fixedly connected to the side wall of the positioning ring 4, a second sealing rubber ring 6 is fixedly connected to the top of the connecting ring 1, a metal collar 10 is fixedly sleeved on the side wall of the upper clamp 9, and multiple conductive brushes 11 are fixedly connected around the side wall of the metal collar 10. The multiple conductive brushes 11 pass through the metal collar 10 and are in contact with the metal conductive strip 8.

[0023] When in use, after the dust-laden gas enters the filter cartridge 2, the dustproof electrostatic cotton 7 and the filter cartridge 2 intercept and filter the dust in the gas, preventing large dust particles from entering the interior of the filter cartridge 2. The dustproof electrostatic cotton 7 has good filtration performance and can effectively block dust particles of different sizes, ensuring the filtration effect. It can also pre-treat the gas entering the interior of the filter cartridge 2.

[0024] During the filtration process, static electricity is generated by the friction between the dustproof and anti-static cotton 7 and the dust in the gas. The metal conductive strip 8 is tightly attached to the side wall of the dustproof and anti-static cotton 7 to conduct the generated static electricity away. Two clamps 9 are clamped onto multiple metal conductive strips 8 to ensure that the metal conductive strips 8 are in close contact with the dustproof and anti-static cotton 7, thereby improving the static electricity conduction efficiency. Multiple conductive brushes 11 on the metal collar 10 on the side wall of the upper clamp 9 are in contact with the metal conductive strips 8 to further enhance the static electricity conduction path and conduct the static electricity to the outside, preventing the accumulation of static electricity from affecting the filtration performance of the filter element and the safe operation of the equipment.

[0025] The first sealing rubber ring 5 on the side wall of the positioning insert ring 4 and the second sealing rubber ring 6 at the top of the connecting ring 1 play a sealing role. When the filter element is installed in the equipment, the first sealing rubber ring 5 fits tightly with the corresponding part of the equipment to prevent dust-laden gas from leaking from the bottom of the filter element; the second sealing rubber ring 6 seals with the upper connection part of the equipment to ensure that the gas can only be filtered through the filter element cylinder 2, thereby improving the filtration efficiency of the filter element and the sealing performance of the equipment.

[0026] To increase the stability of the connection of connecting ring 1, such as Figure 1-3 As shown, multiple mounting slots 12 are provided around the side wall of the connecting ring 1. The inner walls of the multiple mounting slots are respectively set as arc surfaces, and multiple anti-slip silicone strips 13 are fixedly connected to the inner walls of the multiple mounting slots 12.

[0027] Multiple mounting slots 12 on the side wall of the connecting ring 1 are used for connecting with other devices. During installation, the connecting parts of other devices are inserted into the mounting slots 12. The arc design of the mounting slots 12 facilitates the insertion and fixation of the connecting parts. Multiple anti-slip silicone strips 13 are fixed on the inner wall of the mounting slots 12 to increase the stability of the connection and prevent the connecting parts from loosening.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
