Abstract
Description
Technical Field
[0001] This utility model relates to an air filter element, specifically a clog-resistant air filter element suitable for high-concentration dust environments. Background Technology
[0002] In high-dust environments such as industrial production, wood processing, and mineral processing, air filters are crucial components for ensuring the normal operation of production equipment, maintaining a clean working environment, and protecting personnel health. However, traditional air filters used in such environments generally suffer from the following problems:
[0003] Traditional filter cartridges often employ single or two-stage filtration structures. Under the continuous impact of high-concentration dust, a large amount of particulate matter quickly accumulates on the surface of the filter media, causing a sharp increase in the filter cartridge's ventilation resistance and rapid saturation of its dust holding capacity, leading to blockage. This not only significantly shortens the filter cartridge replacement cycle and increases operating costs, but may also affect equipment efficiency or even cause malfunctions due to poor ventilation.
[0004] Many traditional filter cartridges use a single, wound or fixed encapsulated structure, making them either non-removable or extremely inconvenient to disassemble. When dust accumulates on the filter surface and needs cleaning, often only simple external tapping or blowing can be performed, failing to thoroughly clean the inside of the filter cartridge, resulting in poor cleaning effectiveness. In the long run, incomplete cleaning will accelerate the degradation of filter cartridge performance, ultimately leading to its complete disposal and significant waste. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a clog-resistant air filter element suitable for high-concentration dust environments, so as to solve the problems existing in the background art.
[0006] The present invention provides a clog-resistant air filter suitable for high-concentration dust environments, which is achieved through the following technical solutions, including a filter element fixing base, a dustproof structure, a main filtration structure, and an activated carbon filtration structure.
[0007] The filter element holder has an installation position at its front end, and a dustproof structure is fixed at the installation position. The filter element holder has a first fixing position and a second fixing position above it. The main filter structure is fixed to the first fixing position through a plug-in structure, and the activated carbon filter structure is fixed to the second fixing position through a plug-in structure.
[0008] As a preferred technical solution, the dustproof structure includes a dustproof base and a fine filter assembly;
[0009] The dustproof seat has a coarse filter screen on the front, which performs preliminary filtration of dust. The fine filter screen is installed on the back of the dustproof seat. It performs preliminary filtration of air through the coarse filter screen and secondary filtration of air through the fine filter screen assembly, thereby achieving the effect of dust prevention.
[0010] As a preferred technical solution, the main filter plate structure includes a first insert plate and a fine fiber nonwoven fabric layer;
[0011] The fine fiber nonwoven fabric layer is disposed on the first insert plate and is used to filter fine dust; the first insert plate is inserted into the first fixed position through a plug-in structure.
[0012] As a preferred technical solution, the activated carbon filter structure includes a second insert plate and an activated carbon filter layer;
[0013] The activated carbon filter layer is disposed on the second insert plate, and the activated carbon filter layer adsorbs odors in the air; the second insert plate is inserted into the second fixed position through a plug-in structure.
[0014] As a preferred technical solution, the plug-in structure includes a plug-in block disposed on the first plug plate and the second plug plate, and a plug-in groove disposed on the first fixed position and the second fixed position.
[0015] The connector block is guided within the connector slot, thereby enabling the connector installation of the main filter plate structure and the activated carbon filter structure.
[0016] As a preferred technical solution, the fine filter assembly includes a connector and a fine filter disposed on the connector; the connector is inserted into the back of the dustproof seat to facilitate opening and cleaning of the interior of the dustproof seat.
[0017] The beneficial effects of this utility model are:
[0018] This invention employs a coarse filter for initial interception, a fine filter assembly for secondary filtration, and then a fine fiber nonwoven fabric layer in the main filter structure to filter fine dust. This multi-stage progressive filtration method can effectively disperse dust load and prevent particles from rapidly accumulating in a single filter layer, thereby greatly alleviating the problem of filter clogging and extending the service life in high-concentration dust environments.
[0019] Both the main filter structure and the activated carbon filter structure of this utility model are fixed by the cooperation of the plug-in block and the plug-in slot, making installation and disassembly simple; making daily cleaning or periodic replacement of the failed filter material very quick, greatly reducing maintenance costs and time.
