Abstract

The invention discloses an automatic bituminous coal screening device. The automatic bituminous coal screening device comprises a waste box, a U-shaped motor rack, a composite gear shaft, a transmission shaft, a driven gear, a T-shaped elevator, a lower bearing bracket, a guide rail, an upper bearing bracket, an L-shaped motor rack, a sieve rack, two fine-mesh sieves symmetrically mounted on the sieve rack, two eccentric motors, two stepping motors and a rolling lead screw. The lifting motor is used for lifting the fine-mesh sieves; a vibrating motor rotates to drive the fine-mesh sieves to vibrate left and right; the two eccentric motors are capable of driving the fine-mesh sieves to vibrate up and down. The automatic bituminous coal screening device is an automatic instrument reasonable in structure, simple to operate, and capable of screening two parts of bituminous coal particles in a vibrating manner.

Description

technical field [0001] The invention relates to the field of automatic testing of bituminous coal caking index, in particular to an automatic screening device for bituminous coal. Background technique [0002] At present, most of the domestic and foreign countries use semi-automatic experimental methods to measure the cohesive index of bituminous coal: that is, the screening process of bituminous coal adopts manual methods. Usually, the bituminous coal in the drum is collected into a sieve, and then the experimenter shakes the sieve with both hands to sieve out the fine particles (diameter less than 1mm) in the bituminous coal, and the remaining bituminous coal is put into the drum again to rotate the test, repeating this process 3 times, that is, the experimenters need to manually screen the bituminous coal 3 times. There are few automated bituminous coal screening equipment in foreign countries. Manual operation makes the labor intensity of the experimenters high, the wo...
