Description

Technical Field

[0002] The filter element separates solid particles from liquid or gas, or allows different material components to fully contact, speeding up the reaction time, and protecting the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain specification of filter screen, its impurities are blocked, and the clean fluid flows out through the filter element. During the use of the filter element, the solid particles in the liquid or gas will be filtered, so the solid particles will adhere to the surface of the filter element.

After the filtering is completed, the motor 5 is started to rotate the scraper 12, so that the scraper 12 acts on the inner wall of the inner core 8 to scrape off the impurities on the inner wall of the inner core 8. Under the action of gravity, the scraped impurities fall into the dirt storage gap 15, and the inner liner 13 is rotated to separate the inner liner 13 from the sleeve 4, which is beneficial to the cleaning of impurities in the dirt storage gap 15. Gas is input into the air inlet pipe 6 through an external air source. Through the setting of the air supply pipe 7 and the air holes, the inside of the installation gap 10 can be blown, which is beneficial to the treatment of particulate matter on the outer wall of the inner core 8 and the filter paper layer 9. Through this air blowing effect, the damage to the inner core 8 and the filter paper layer 9 can be minimized, thereby improving the practicability of the equipment. After cleaning, the impurities in the installation gap 10 can be discharged by disassembling the lower end cover 3.
