Technical Field
[0001] This utility model relates to the field of antistatic dust collector filter element structure, and more specifically, to an antistatic dust collector filter element structure. Background Technology
[0002] A dust collector filter element is a type of filter element used to filter particulate matter and dust from the air. Dust collector filter elements are made of materials such as metal fibers, glass fibers, non-woven fabrics, and composite materials. Their advantages include high temperature resistance, corrosion resistance, large dust holding capacity, and high filtration efficiency.
[0003] According to the publication number of Chinese Utility Model Patent: CN 208130711 U, a dust removal filter element is disclosed. This dust removal filter element cannot remove the static electricity generated by itself and dust, so that dust will be adsorbed on the filter element during use, which increases the number of times the filter element needs to be cleaned. Furthermore, when the filter cotton inside the filter element is damaged, the entire filter element needs to be replaced, which is not very practical.
[0004] Furthermore, in the prior art, such as the authorized announcement number CN220276557U, this utility model relates to the field of dust collector filter technology and discloses an anti-static dust collector filter, including a filter element seat, a filter plate fixedly installed on the lower side of the filter element seat, filter cotton provided on the outer side of the filter plate, and a metal ring snapped onto the outer side of the filter cotton. In use, this anti-static dust collector filter allows the negative ion generator to continuously generate negative ions, which are conducted to the filter cotton through the metal ring, neutralizing the static electricity within the filter cotton and preventing its generation. The motor output drives the rotating shaft to rotate, causing a brush on the outer side of the fixed plate to clean the filter plate and filter cotton, sweeping away the adsorbed dust. Regular cleaning increases the lifespan of the filter cotton. Rotating the fixed ring detaches it from the filter plate, allowing the filter cotton to be removed and replaced without replacing the entire filter element, saving replacement costs and increasing the practicality of the device.
[0005] When filtering and adsorbing, the filter cotton adsorbs dust from the outside. The dust adheres to the folds of the filter cotton. The aforementioned patented internal cleaning method cannot clean the dust. In addition, the motor is costly. It is inconvenient to disassemble and quickly remove the filter cotton for replacement and cleaning, making it inconvenient to use. Furthermore, the support ring is clamped to the outside of the filter cotton, which is a soft structure, making it impossible to install securely. Utility Model Content

A pleated filter element is sleeved on the outer surface of the dust collector support cylinder body 1. The paper tube 6, with one side of the pleated filter paper tube 6 snapped onto the inner surface of the snap-fit cover 2, and the other side of the pleated filter paper tube 6 snapped onto the inner surface of the support ring 4, has a threaded post 7 fixed to the surface of the dust removal support screen body 1, and the snap-fit cover 2 is fixed to the outer surface of the threaded post 7 by a nut 8; by setting a positioning ring on the outside of the dust removal support screen body, and fixing the support ring to the surface of the positioning ring by screws, the installation is stable and firm, and the snap-fit cover is fixed to the outside of the dust removal support screen body by a nut, making disassembly convenient, disassembling the pleated filter paper tube convenient, maintenance convenient, simple structure, and low cost;
[0027] The inner end of the support ring 4 has an annular protrusion with an annular groove 40. The inner surface of the annular groove 40 of the support ring 4 is engaged with the outer surface of the positioning ring 3. This facilitates engagement and positioning, allows for merging, and ensures stable installation with the positioning ring 3.
[0028] The surface of the positioning ring 3 is provided with threaded holes, and the annular protrusion of the support ring 4 is provided with through holes; so as to facilitate the insertion of screws 5.
[0029] The threaded posts 7 are distributed on the left and right sides of the upper and lower end faces of the dust removal support screen cylinder body 1; they are distributed on both sides, and when the mounting nuts 8 are tightened and fixed, the installation is stable;
[0030] The snap-fit cover 2 has an insertion hole on its surface, and the insertion hole of the snap-fit cover 2 is sleeved on the outer surface of the threaded post 7; this facilitates the sleeve installation. The threaded post 7 is welded and fixed to the surface of the dust removal support mesh cylinder body 1, which is made of metal mesh cylinder material; this ensures a firm fixation.
[0031] A negative ion generator 9 is installed on the outer surface of the support ring 4. (A negative ion generator is a device that generates negative air ions. This device processes the input DC or AC power through an EMI processing circuit and a lightning protection circuit, then raises it to AC high voltage through a pulse circuit, overvoltage current limiting, and high and low voltage isolation circuits. After rectification and filtering by special grade electronic materials, a pure DC negative high voltage is obtained. The DC negative high voltage is connected to a release tip made of metal or carbon element. The high voltage at the tip generates a high corona discharge, which releases a large number of electrons (e-) at high speed. Since electrons cannot exist in the air for long (the lifespan of existing electrons is only on the order of nanoseconds), they are immediately captured by oxygen molecules (O2) in the air, thereby generating negative air ions. This is existing technology.) A power cord is installed at the outer end of the negative ion generator 9 for easy conductivity. During use, the negative ion generator can continuously generate negative ions when the filter element is in use. The negative ions are conducted to the filter cotton through the metal ring, neutralizing the static electricity in the filter cotton and preventing the filter cotton from generating static electricity. This is existing technology.

Tightening the nut 8 secures the tube, making the installation of the pleated filter paper tube 6 convenient.
[0033] When in use, the snap-fit cover 2 can be removed when the nut 8 is disassembled, making it easy to take out the pleated filter paper tube 6 for replacement and cleaning. It is convenient to use and easy to disassemble.
