[0002] As an important air purification device, the dust collector's main function is to separate and remove solid particles from dust-laden gases, thereby purifying the air and protecting the environment and human health. Existing dust collectors have a complex overall structure and numerous components, which not only increases the difficulty of installation and maintenance, but may also lead to an increase in failure rates.

[0003] Therefore, it is necessary to propose a self-priming breathing dust collector to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of the present invention is to provide a self-priming breathing dust collector to solve the problem that the existing dust collector proposed in the above background technology has a complex overall structure and numerous components, which not only increases the difficulty of installation and maintenance, but also may lead to an increase in the failure rate.

[0005] Technical solution: To achieve the above objectives, the utility model is implemented through the following technical solutions: a self-priming breathing dust collector, comprising a filter cartridge, wherein the output end of the filter cartridge is provided with an exhaust pipe, and a back-blowing air solenoid valve and a high-pressure gas tank are fixedly installed on one side of the filter cartridge, and the upper and lower ends of the high-pressure gas tank are respectively fixedly provided with an outlet pipe and an air inlet pipe connected to their interior, the other end of the outlet pipe is connected to the input end of the back-blowing air solenoid valve, and a valve is provided on the inlet pipe; a filter element is provided inside the filter cartridge, comprising a fixed cartridge with an opening at the top and a filter bag sleeved on the outside of the fixed cartridge, and air holes are evenly opened on the circumference and bottom surface of the fixed cartridge, and a fixing ring is fixedly sleeved on the outside of the top of the fixed cartridge, and the fixing ring is fixedly connected to the inner wall of the filter cartridge; a back-blowing pipe is fixedly installed in the filter cartridge above the filter element, one end of the back-blowing pipe extends into the fixed cartridge, and the other end passes through the filter cartridge and is connected to the output end of the back-blowing air solenoid valve.

[0006] Preferably, a clamping assembly is fixedly installed on one side of the filter cartridge, and the high-pressure gas tank is detachably mounted on the filter cartridge through the clamping assembly. The clamping assembly includes two U-shaped bolts and two fixing frames fixedly installed on the filter cartridge at vertical intervals. Both fixing frames have two through holes in the longitudinal direction, and the two ends of the two U-shaped bolts pass through the two through holes on the adjacent side fixing frames respectively.

[0007] Preferably, the filter cartridge comprises a lower cylinder, an upper cylinder and flanges fixedly mounted on adjacent ends of the lower cylinder and the upper cylinder, and the lower cylinder and the upper cylinder are detachably connected together via the flanges.

[0008] Preferably, a ring platform is fixedly mounted on the inner wall of the lower cylinder, and the fixing ring and the ring platform are fixedly connected together by bolts.

[0009] Beneficial effect: Compared with the prior art, the utility model provides a self-priming breathing dust collector, which has a unique structure and is easy to use. When the dust collector starts working, the gas containing dust enters from the input end of the filter cartridge, and the gas is then filtered through the filter bag. The filter bag can effectively capture the dust particles in the gas, and the clean gas enters the space above the filter element through the air holes on the filter bag and the fixed cartridge, and is finally discharged through the exhaust pipe; when the dust on the filter bag accumulates to a certain extent, it needs to be cleaned. At this time, the dust collector can be removed from the exhaust channel and the back-blowing solenoid valve can be opened. After the back-blowing solenoid valve is opened, the high-pressure gas in the gas tank enters the back-blowing solenoid valve through the outlet pipe, and after being regulated by the solenoid valve, it enters the fixed cartridge through the back-blowing pipe. The high-pressure gas expands rapidly in the fixed cartridge, pushing the filter bag to expand outward, thereby shaking off the dust particles attached to the surface of the filter bag.

[0010] The dust collector has a simple structure and is easy to install and disassemble, which greatly simplifies the installation process. In addition, this structural design makes the dust collector more stable and reliable during operation and reduces the failure rate. At the same time, the compact structural design reduces the footprint and weight of the dust collector, making it more suitable for various occasions. BRIEF DESCRIPTION OF THE DRAWINGS
