The cartridge dust collector usually consists of a cartridge assembly, and the cartridge is installed in a slanted, side-mounted and hanging manner, etc., and a cleaning system. The cleaning system is often equipped with a pulse airflow generator to provide high-pressure compressed air as the power source of the pulse airflow generator, and then release the pulse airflow so that it can perform pulse cleaning on the cartridge. The working process of the cartridge dust collector usually includes the following steps: Air enters the cartridge dust collector: Air containing particulate matter enters the cartridge dust collector through the air inlet. Particles are filtered out: Air passes through the cartridge assembly, particulate matter is filtered out, and clean air is discharged through the cartridge. Particles are deposited on the surface of the cartridge: As air flows through the cartridge, particles are deposited on the surface of the cartridge. The cleaning system cleans the cartridge: When a certain amount of particulate matter accumulates on the surface of the cartridge, the cleaning system will start to clean the particles on the surface of the cartridge to maintain the dust removal effect. Discharge clean air: The air after dust removal by the filter cartridge is discharged into the environment to keep the air clean.

[0003] The filter cartridge inside the existing filter cartridge dust collector is generally fixed when installed in the filter box. After long-term use, impurities will accumulate around the filter cartridge, causing blockage of the filter cartridge, thereby reducing the dust removal efficiency of the filter cartridge dust collector.

[0024] Example:

[0025] Reference Figure 1-Figure 4 A filter cartridge dust collector includes a filter box 1, in which a filter cartridge 2 is detachably provided. The filter cartridge 2 is the core component of the dust collector and is mainly used to filter particulate matter, dust and solid particles in the air to protect the environment and personnel health. The filter cartridge 2 is usually made of high temperature resistant and corrosion resistant filter material, such as polyester fiber, polypropylene fiber, glass fiber and other materials. The structure of the filter cartridge 2 is generally long and cylindrical, with a large filtering area to improve the dust removal efficiency. At the same time, it can be detachably forked in the filter box 1, and the connecting end of the filter cartridge 2 is fixedly locked to the outside of the filter box 1.

[0026] A pulse airflow generator is also provided on the outside of the filter box 1. The pulse airflow generator is a device for generating pulse airflow, which is usually used for cleaning, dust removal, drying, conveying and other applications. The pulse airflow generator can effectively remove dust, particles or impurities accumulated on the surface by periodically releasing high-speed airflow pulses, thereby achieving the purpose of cleaning and dust removal. The pulse airflow generator usually includes the following components: Compressed air source: provides high-pressure compressed air as the power source of the pulse airflow generator. Control system: used to control the working mode, frequency and release of pulse airflow of the pulse airflow generator. Pulse valve: used to control the release of airflow, usually using a solenoid valve or a pneumatic valve. Airflow duct: transmits compressed air to the area that needs to be cleaned or dust removed.

[0027] A pulse jet tube 6 is also provided in the filter box 1, and the jet end of the pulse jet tube 6 faces the outside of the filter cartridge 2, and the air inlet end of the pulse jet tube 6 can be connected to the airflow duct, so that the accumulated dust on the outside of the filter cartridge 2 can be pulse cleaned, thereby effectively removing the dust accumulated on the outside of the filter cartridge 2, restoring the normal working state of the filter cartridge 2, and improving the dust removal efficiency.

[0028] Embodiment 2:

[0029] In order to better clean the accumulated dust outside the filter cartridge 2, please refer to Figure 3 and Figure 4 As shown in the figure, a toggle plate 3 is connected to the filter box 1 through a flexible connector, and a through hole is opened on the surface of the toggle plate 3 to prevent the gas flowing inside from being affected. The flexible connector can be made of rubber, spring, plastic or other materials. When the toggle plate 3 is displaced, the flexible connector can be elastically deformed to compensate for the displacement and maintain the stability of the connection of the toggle plate 3.

[0030] At the same time, a contact block 301 is fixedly connected to the side of the toggle plate 3 facing the filter cartridge 2. An air intake pipe is also provided on the filter box 1, and the air intake pipe can be kept parallel to the direction of the filter cartridge 2. The air intake pipe is provided in the device parallel to the filter cartridge 2. The air intake pipe can be used to transport high-pressure gas containing dust to the interior of the filter box 1. Then, the dust in the gas will be filtered by the filter cartridge 2 to filter the dust in the air, and then the purified air will be discharged through the middle position of the filter cartridge 2.

[0031] A knocking cylinder 4 is also installed in the filter box 1, and a knocking rod 5 is slidably connected to the knocking cylinder 4, and the knocking rod 5 can be abutted against the outer wall of the toggle plate 3, and a piston 502 is slidably connected in the knocking cylinder 4, one end of the knocking rod 5 is fixedly connected to the piston 502, and then the air inlet of the knocking cylinder 4 is connected to the output end of the pulse airflow generator through a pipeline, and the air outlet of the knocking cylinder 4 is connected to the pulse jet pipe 6 through a pipeline, and a limit spring 501 is arranged in the knocking cylinder 4, and the two ends of the limit spring 501 are respectively fixedly connected to the piston 502 and the knocking cylinder 4, so that the position of the knocking rod 5 can be reset.

[0032] When the pulse jet tube 6 is started and the filter cartridge 2 is cleaned as needed, the high-speed airflow first enters the interior of the knocking cylinder 4, and the pipe on the knocking cylinder 4 connected to the pulse jet tube 6 is set at the end of the knocking cylinder 4, and the limit distance is the limit compression length of the limit spring 501, and then the high-speed airflow pushes the piston 502 in the knocking cylinder 4 at high speed. At this time, the piston 502 will drive the knocking rod 5 to move quickly to the outside. At this time, the knocking rod 5 is against the toggle plate 3 and pushes the toggle plate 3 to make it in an inclined state. The reset spring 302 on the movable plate 3 is compressed and abuts against the inner wall of the filter box 1, and the flexible connector at the bottom of the movable plate 3 can limit the movable plate 3. Then the gas is sprayed to the outside of the filter cartridge 2 through the pulse jet tube 6. At this time, the knocking rod 5 is reset by the limit spring 501 to reset the piston 502. At this time, the movable plate 3 moves toward the end of the filter cartridge 2, and the contact block 301 can abut against the end of the filter cartridge 2 and knock it, so that the accumulated dust on the filter cartridge 2 can be cleaned again, thereby improving the dust removal efficiency of the filter cartridge 2.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
