Self-cleaning type roller screening coal separating machine

Abstract

The invention discloses a self-cleaning type roller screening coal separating machine which comprises a roller and fixing frames. The fixing frames are arranged at the two ends of the roller. The roller is horizontally arranged between the fixing frames. The roller is formed by splicing multiple frame bodies. The frame bodies include longitudinal frame bodies and round frame bodies. Screens are connected between the frame bodies and include rough filtering screens, medium filtering screens and fine filtering screens, and the screens are separated through the round frame bodies. A center shaftis connected with the center of the roller in a penetrating manner, and the two ends of the center shaft are connected with the fixing frames. A speed reduction motor is arranged on each fixing frameand is connected with the center shaft. The center shaft is of a hollow structure, and multiple water spraying holes are formed in the surface of the center shaft. The lower end of each fixing frame is provided with a hydraulic lifting device. By means of the above manner, the phenomenon that the screens of the roller wall of the roller coal separating machine are blocked by coal slime can be effectively avoided.

Description

technical field [0001] The invention relates to the field of coal separators, in particular to a self-cleaning drum screening coal separator. Background technique [0002] Drum screening coal separator is another new generation of special equipment for screening materials after the common mesh drum screen produced by major domestic companies. It is widely used in the screening of various solid materials with a particle size of less than 300mm, and has high screening efficiency. High performance, low noise, small amount of dust, long service life, small amount of maintenance, convenient maintenance and many other characteristics, and its screening capacity is more than 60 tons per hour. Comprehensive utilization power stations mainly burning low-quality coal are rapidly rising in China. Coal ore and coal slime are usually sticky, wet, dirty, and miscellaneous. Low, high wear and tear of the crusher, high energy consumption, etc. At present, there is no effective solution to ...
