Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air filter cartridge structure with auxiliary cleaning function. Background Technology

[0002] Because industrial production generates a large amount of dust, workers who work in dusty environments for extended periods are susceptible to pneumoconiosis. Pneumoconiosis poses a significant threat to people's health and is difficult to cure. For the sake of workers' health, factories should install dust collectors to treat the dust. Filter cartridges are an important component of dust collectors. Filter cartridges, also known as air filter elements or air purifiers, are cylindrical filtration devices primarily used to intercept and remove particulate matter, dust, and other impurities from the air.

[0003] China Patent Network (patent publication number CN214345179U) discloses an air filtration cartridge, including a metal mesh support, a pleated filter material, a cover plate, and a base. A motor is detachably installed inside the base. The pleated filter material is detachably fixed to the metal mesh support. The metal mesh support has a bottom plate and an opening at the top. The rotating shaft of the motor is fixedly connected to the bottom plate for rotation. An extendable outer cover is fixed on the base. When the outer cover rises to completely cover the outside of the pleated filter material, the cover plate closes on the outer cover.

[0004] In use, the aforementioned air filter cartridges use a rotating metal mesh support to shake off dust from the filter media surface, making cleaning easier. However, in actual use, whether using internal pressurized air blowing or the rotating shaking method, dust will adhere to the pores on the filter cartridge surface when the air has a certain level of humidity. This makes it difficult for internal air blowing and rotating shaking to clean the dust quickly, leaving residue and affecting the normal use of the filter cartridge after cleaning. Therefore, we propose an air filter cartridge structure with auxiliary cleaning function. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below.

[0028] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] This utility model provides, for example Figure 1-4 The air filter cartridge structure shown includes a filter cartridge body 1, a cover frame 2 connected to one end of the filter cartridge body 1, an auxiliary cleaning mechanism 3 attached to one side of the outer wall of the filter cartridge body 1, the filter cartridge body 1 includes an outer filter cartridge 101, guide rails 102 fixed on both sides of the inner wall of the outer filter cartridge 101, and an inner filter cartridge 103 attached to the four sides of the inner wall of the outer filter cartridge 101.

[0030] To provide stable filtration efficiency and convenient replacement, such as Figure 1-2 As shown, this filter cartridge structure consists of an outer filter cartridge 101 with an external filter screen structure and an inner filter cartridge 103 that is attached to the inner wall. The inner filter cartridge 103, made of internal polyester non-woven adhesive filter material, maintains a stable filtration effect on dust and in humid environments. When replacing and cleaning, the inner filter cartridge 103 can be slid out through the guide rail 102 structure for easy replacement.

[0031] like Figure 3 As shown, the cover frame 2 includes an end cover 201, and the inner wall of the end cover 201 is connected to a threaded post 202. The outer wall of the threaded post 202 is threaded to one end of the filter cartridge body 1. The outer wall of the end cover 201 is axially connected to a rotating shaft 203. The end of the rotating shaft 203 is fixed with a limit post 204. The outer wall of the rotating shaft 203 is fitted with a shaft cap end 302.

[0032] To facilitate the disassembly and replacement of the filter cartridge, such as Figure 3 As shown, one end of the outer filter cartridge 101 of this filter cartridge structure is connected to the end cap 201 via a threaded post 202. In use, the threaded post 202 can be rotated to unscrew it, thereby replacing the filter element of the inner filter cartridge. The rotating shaft 203 fixed on the other side can provide axial connection stability for the shaft cap end 302, maintaining the stability of the scraper frame 301 during the cleaning process.

[0033] like Figure 4-5As shown, the auxiliary cleaning mechanism 3 includes a scraper frame 301. One end of the scraper frame 301 is connected to a shaft cap end 302, and a handle 303 is fixed to the end of the shaft cap end 302. The other end of the scraper frame 301 is connected to a shaft cap tail 304. A hollow shaft tube 305 is sleeved on the inner wall of the shaft cap tail 304. Connecting brackets 306 are connected to both sides of the hollow shaft tube 305. A latch 307 is inserted into the inside of the scraper frame 301. A scraper strip 308 is fixed to the bottom end of the latch 307. A brush layer 309 is connected to one side of the bottom end of the scraper strip 308.

[0034] Finally, in order to improve the overall cleaning efficiency and auxiliary cleaning quality of the filter cartridge, such as... Figure 4-5 As shown, this filter cartridge structure has a scraper frame 301 on its outer wall. The scraper frame 301 can be rotated through the shaft cap end 302 and shaft cap tail 304 connected to its two ends. The user can turn the handle 303 outside the air purification equipment to make the entire scraper frame 301 rotate along the outer wall of the outer filter cartridge 101. In conjunction with the brush layer 309 and scraper strip 308 inserted into the inner wall of the scraper frame 301, the scraper frame 301 brushes and scrapes the dust adhering to the outer wall of the outer filter cartridge 101, forming an auxiliary process for blowing dust away from the internal pressurized air, thereby improving the cleaning efficiency and quality of the filter cartridge surface.

[0035] In summary, when using this filter cartridge structure, the user can first insert the entire filter cartridge body 1 into the air purification device. The outer filter cartridge 101 and inner filter cartridge 103 of the filter screen structure filter and intercept humid air. Some of the humid dust adheres to the surface of the filter cartridge. For cleaning, pressurized air first passes through the pressurization pipe into the hollow shaft tube 305 to blow dust into the inside of the filter cartridge. Simultaneously, the user can hold the handle 303 externally and rotate the shaft cap end 302 connected to the handle 303, thus driving the shaft cap... The scraper frame 301 fixed on one side of the end 302 rotates synchronously, so that the scraper strips 308 and brush layer 309 on the inner wall of the scraper frame 301 clean the surface of the filter cartridge as it rotates. When replacement and maintenance are required, the filter cartridge can be pulled out of the air purification equipment. Then, the bolt fixing assembly of the shaft cap tail 304 and the shaft cap end 302 can be removed and separated. The scraper frame 301 can be removed, and the end cap 201 can be taken out by rotating the threaded post 202. Then, the inner filter cartridge 103 can be slid out from the filter cartridge for cleaning and replacement.
