Description

Technical Field

[0001] The utility model specifically relates to the technical field of Roots blower cleaning, in particular to a self-cleaning and anti-clogging Roots blower with a large air inlet. Background Art

[0002] Roots blower is a positive displacement blower with the characteristics of simple structure, easy operation, medium is not easily contaminated, and air volume changes little when pressure changes. It is widely used in steel, mining, food, fiber, papermaking, chemical industry, aquaculture oxygenation, sewage treatment aeration, cement transportation and other industrial sectors.

[0003] During the use of the Roots blower, a filter is arranged inside the air inlet pipe to effectively filter the dust, impurities or particles in the gas, thereby preventing them from entering the interior of the Roots blower. However, when cleaning the traditional filter, it is necessary to manually disassemble the air inlet pipe, which will affect the normal use of the Roots blower. When cleaning the filter, the Roots blower cannot be in working condition, which will result in low efficiency.

[0004] After searching, Chinese patent publication number CN202223487558.6 discloses an air supply Roots blower that is easy to clean; it includes a blower body, a second motor and an air outlet, and an air inlet muffler is arranged above the blower body. This air supply Roots blower that is easy to clean can filter the inhaled air through a cleaning box arranged on the surface of the air inlet muffler, so that dust and impurities contained in the air can be filtered by the filter cotton arranged inside the cleaning box, and when the first motor is started, it can drive the first threaded rod connected to the output end to rotate, so that the first threaded rod can drive the threaded sleeve connected to the surface to move, so that the threaded sleeve can drive the connected scraper to move, so that the scraper can scrape the impurities and dust filtered on the surface of the filter cotton, and the impurities and dust can be collected by a collection box arranged on one side;

[0005] When the device in the above patent cleans the Roots blower, the first motor drives the first screw to rotate, and then the threaded sleeve installed on the surface of the first screw is used to move the scraper, thereby achieving the cleaning effect of the filter cotton. However, when the scraper in the above patent moves, it may cause dust to be further collected inside the filter surface, which cannot effectively ensure that the dust is cleaned. Therefore, the cleaning structure in the above patent still has certain technical defects. Utility Model Content
