Abstract

The invention provides an anti-blocking rotary screen, and relates to the technical field of screening equipment, so as to solve the problem that the comb-type cleaning device of the existing anti-blocking rotary screen is bad in cleaning effect and easy to be damaged. The anti-blocking rotary screen comprises a rotationally installed cylindrical screen drum. A main shaft in parallel with the central axis of the screen drum is arranged inside the screen drum. The main shaft rotates in synchronization with the screen drum. A plurality of smooth shafts for connecting the main shaft with the screen drum is further arranged inside the screen drum. All the smooth shafts are sleeved with vibrating hammers which are able to slide freely. The anti-blocking rotary screen is simple in structure, reasonable in arrangement, convenient in installation, good in blockage cleaning effect, saves the time for cleaning the screen drum manually, avoids the occurrence of unnecessary human body and mechanical damages, and reduces labor intensity. The anti-blocking rotary screen can also screen materials whose water content is more than 15%. The anti-blocking rotary screen shortens the screening time, increases the production efficiency, and the anti-blocking rotary screen is stable in production operations, and can be used for years without maintenance.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to an anti-blocking drum screen. Background technique [0002] The trommel screen is mainly a device for screening and separating solid materials. The materials entering the trommel screen are turned and rolled along with the rotation of the screen drum. The qualified materials are discharged through the discharge port at the bottom of the screen drum, and the unqualified materials are screened. The discharge port at the end of the barrel is discharged. Due to the difference in particle size, humidity, composition content and particle shape of the material itself, there are also different requirements for screening equipment; in order to prevent the clogging of the drum screen cylinder and improve the screening efficiency, scientific and technological workers have studied the anti-blocking drum screen. [0003] At present, the existing anti-blocking drum screen is provi...
