Screening and cleaning equipment capable of controlling sizes of coal particles

Abstract

The invention discloses screening and cleaning equipment capable of controlling the sizes of coal particles. The screening and cleaning equipment comprises a processing box, a processing cavity is formed in the processing box, a feeding cavity with an upward opening is formed in the upper wall of the processing cavity in a communicating mode, and symmetrical belt wheel cavities are formed in the left side and the right side of the feeding cavity; symmetrical belt cavities located on the front side and the rear side of the feeding cavity are formed between the left belt wheel cavity and the right belt wheel cavity in a communicating mode, and left-right symmetrical vibration cavities are formed in the left wall and the right wall of the processing cavity in a communicating mode and connected with connecting plates in an up-down sliding mode; and screening boxes connected with the processing cavity in an up-down sliding manner are fixedly connected with the end faces of the sides, closeto each other, of the left connecting plate and the right connecting plate. According to the screening and cleaning equipment, the size of coal particles is controlled through a screening cavity withthe distance capable of being adjusted, vibration is generated through a cam and a spring, accordingly, the screening cavity is prevented from being blocked, meanwhile, a push plate in the left-rightdirection is arranged, large-particle coal can be pushed leftwards and rightwards to be crushed.

Description

technical field [0001] The invention relates to coal-related fields, in particular to a screening and cleaning device capable of controlling the size of coal particles. Background technique [0002] In coal processing, after the coal is mined out of the raw stone, it needs to be processed into a shape with a suitable particle size according to the demand, and during the mining process of the coal, there will be sediment, dust, and some gravel attached to the raw stone, all of which need to be processed However, it is difficult for some existing coal processing equipment to sieve according to the particle size of the coal, which is difficult to meet the needs of the market, and it is difficult to remove impurities while sieving, and to perform a large-scale cleaning at the same time, which is less functional. Poor, a kind of screening and cleaning equipment that can control the size of coal particles described in the present invention can solve the above problems. Contents ...
