DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example 1: A gauze-type pulse filter cartridge dust collector, see Figures 1 to 4, including a dust collecting cylinder 1, one side of the dust collecting cylinder 1 is connected with an air inlet pipe 11, the top of the dust collecting cylinder 1 is penetrated with an exhaust pipe 12, a filter cartridge 14 is installed on the exhaust pipe 12 in the dust collecting cylinder 1, a dust collecting mechanism is installed on the outside of the filter cartridge 14, the dust collecting mechanism includes a cleaning disc 22 and a servo motor 2 installed on the top of the dust collecting cylinder 1, a through hole 23 is opened at the center of the cleaning disc 22, the cleaning disc 22 is sleeved on the outside of the filter cartridge 14 through the through hole 23, a cleaning brush 24 is installed on the inside of the through hole 23, and the servo motor 2 is installed on the outside of the filter cartridge 14. A screw rod 21 is installed at the driving end of the motor 2, and the screw rod 21 passes through the cleaning disk 22 and is threadedly connected to the cleaning disk 22; the bottom end of the dust removal cylinder 1 is connected to the dust storage box 3, and the bottom of the dust storage box 3 is open. A connecting shaft 51 is rotatably connected between the two sides of the inner cavity of the dust storage box 3, and a feeding roller 52 is fixedly connected to the outer side of the connecting shaft 51. Dust storage grooves 53 are opened on both sides of the feeding roller 52, and filter frames 54 are installed in the two dust storage grooves 53. A driving motor 5 is installed on one side of the dust storage box 3. The driving end of the motor 5 is connected to the connecting shaft 51, and a negative pressure pump 4 is installed on the side of the dust storage box 3 away from the driving motor 5. An air suction pipe 41 is connected to the suction end of the negative pressure pump 4. The connecting shaft 51 is a hollow structure. A rotating joint 42 is installed on the side of the connecting shaft 51 close to the negative pressure pump 4. The rotating joint 42 is connected to one end of the air suction pipe 41. A connecting pipe 43 is connected between the connecting shaft 51 and the two dust storage grooves 53. By starting the servo motor 2 to drive the screw rod 21 to rotate, the cleaning disc 22 can be driven to move up and down reciprocatingly, so that the cleaning brush 24 can be used to clean the dust adsorbed on the surface of the filter cartridge 14 and separate it from the filter cartridge 14. Then, the negative pressure pump 4 is started to generate negative pressure in the dust storage box 3, thereby accelerating the dust to fall and be collected in the filter frame 54. When a large amount of dust is collected in the filter frame 54, the driving motor 5 is started to drive the falling roller to rotate 180°, so that the filter screen that collects a large amount of dust opens downward, so that the dust collected in the filter frame 54 is automatically discharged from the dust storage box 3, thereby greatly improving the dust removal efficiency.

[0021] It is worth noting that see Figure 3 A valve 13 is installed on the outside of the air inlet pipe 11. When the filter cartridge 14 is dusted, the valve 13 is closed manually so that negative pressure is generated in the dust storage box 3. The air outside the dust cartridge 1 can only enter the dust cartridge 1 from the exhaust pipe 12, so that the incoming air can backwash the filter cartridge 14, thereby improving the dust removal effect of the filter cartridge 14.

[0022] It is worth noting that see Figure 4 A gauze 7 is provided on the outer side of the filter cartridge 14, and the exhaust gas is filtered through the gauze 7 so that large particles of dust and other impurities inside the exhaust gas adhere to the surface of the gauze 7 to prevent them from entering the filter element and causing damage to the filter element. The gauze 7 is placed between the filter cartridge 14 and the cleaning brush 24, and the cleaning brush 24 is fitted with the surface of the gauze 7 to ensure that the cleaning brush 24 can clean the dust on the surface of the gauze 7.

[0023] It is worth noting that see Figure 2 Sealing rubber discs 6 are fixedly connected to both sides of the unloading roller 52, and the connecting shaft 51 rotates and penetrates the sealing rubber discs 6. Through the setting of the sealing rubber discs 6, the sealing performance of the connection between the unloading roller 52 and the dust storage box 3 can be increased, thereby preventing dust from being discharged from the gap between the unloading roller 52 and the dust storage box 3 to affect dust collection.

[0024] In addition, the components designed in the present invention are all universal standard parts or components known to technical personnel in the field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. They can be fully implemented by technical personnel in the field, and there is no need to elaborate. The content protected by the present invention does not involve improvements to internal structures and methods.

[0025] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
