Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of the viscosity of the coal particles in the prior art, the fine particles are easier to attach to the larger particles to make the coal stick into agglomerates, and the sieve screen in the prior art Single, resulting in some coal particles smaller than the size of the sieve cannot pass through the sieve, which affects the screening accuracy and efficiency, and a screening equipment for coal mining and its use method are proposed

Abstract

The invention discloses screening equipment for coal mining and a using method thereof, and belongs to the technical field of coal mining and screening. The screening equipment for coal mining comprises a base, front cross beams and rear cross beams, wherein the front cross beams are higher than the rear cross beams; the front cross beams and the rear cross beams are separately and fixedly arranged on the top of the base; shaking support mechanisms are fixedly arranged on the tops of the front cross beams and the rear cross beams; and a screening shell is connected with the front cross beams and the rear cross beams through the shaking support mechanisms. According to the screening equipment, a movable screen mesh is driven through a power mechanism to do reciprocating screening so as to screen coal, and when the movable screen mesh is moved, a traction connecting rod can be driven through a following mechanism to be moved, and thus, the screening shell is towed through the traction connecting rod, and the coal which is fallen on a fixed screen mesh is further screened; and moreover, by utilizing synchronous shaking of the movable screen mesh and the fixed screen mesh, full screening of coal particles can be realized, and the problems that the coal particles are aggregated into pellets and the screening accuracy and efficiency are low in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of coal mining screening, in particular to a screening device for coal mining and a method for using the same. Background technique [0002] In the process of coal mining, due to the different burial depths of coal resources, mine mining (deep burial) and open-pit mining (shallow burial) are generally used accordingly. It has been one of the main energy sources used by the human world for centuries. Coal is still one of the indispensable energy sources for the production and life of human society at present and for a long time to come. Existing coal needs to be screened after being mined. [0003] Traditional coal screening mainly screens coal through the vibrating screen inside the machine. For example, the patent application number is 201611255020.9, the application publication number is CN106824770A, and the name is powdered coal screening device. The disclosed technical solution drives the screen by sett...
