Abstract

The invention introduces the method of drum-type hook-tooth screening and impurity removal, including the use of drum-type hook-tooth screening and removal of impurities to process raw coal, including (1) assembling the drum-type hook-tooth screening and removal of impurities; (2), The drum-type hook-tooth screening and impurity removal equipment is connected to an external power supply; and started; (3), the raw coal is added to the drum-type hook-tooth screening and impurity removal equipment through the transmission or transportation equipment; (4), the raw coal is separated by screening into large Lump material and coal powder. The root of this patent solves the situation that the screen is blocked. The rolling drum and the hook tooth shaft with rotating function are used together to ensure the screening effect; the situation of the screen being blocked is avoided; the transmission device at the bottom of the equipment will screen out The pulverized coal is collected and transported to the left side of the equipment for accumulation, and the larger coal lumps flow out through the opening on the right side of the trommel screen.

Description

technical field [0001] The invention relates to a technique in the field of screening and impurity removal, in particular to a drum-type hook tooth screening and impurity removal method. Background technique [0002] The impurity removal of raw coal generally includes coal washing and screening. [0003] Coal washing: The coal mined directly from the mine is called raw coal. The raw coal is mixed with many impurities during the mining process, and the quality of the coal is also different. The coal with small internal ash and large internal ash are mixed together. Coal washing is an industrial process that removes impurities in raw coal, or classifies high-quality coal and low-quality coal. The products produced after the coal washing process are generally divided into gangue, medium coal, B-grade clean coal, and A-grade clean coal. The finished coal after the coal washing process is usually called clean coal. Through coal washing, the cost of coal transportation can be red...
