A kind of coal screening equipment

Abstract

The invention relates to a coal screening equipment, which comprises a bottom plate and four circular vibrating screens distributed around the center of the bottom plate, screens with different apertures are distributed in the vibrating screen, and a plurality of screens installed on the bottom plate to store multiple screens. There is a storage rack, and a conveying device for transporting the screen to the corresponding vibrating screen is distributed above the bottom plate, and a lifting mechanism is provided on the bottom plate to drive the storage rack up and down. The invention realizes multi-aperture screening of raw coal without multiple screening, reduces screening steps, shortens screening time, and transports sieve plates with different apertures into the corresponding vibrating screen through the cooperation of the conveying device and the lifting mechanism, without manual installation , Reduce the work intensity of workers, shorten the screening preparation time, and enhance the screening efficiency.

Description

technical field [0001] The invention relates to the field of coal screening, in particular to coal screening equipment. Background technique [0002] my country has always been a big country for mining and using coal. Coal is prone to produce toxic gases such as sulfur dioxide. As the country continues to increase its efforts to improve the environment, it is necessary to subdivide coal for use. Traditional coal screening equipment can only screen a single aperture. The raw coal cannot be further subdivided, resulting in the mixed combustion of a large amount of high-quality raw coal and raw coal containing more impurities. The combustion efficiency is low, and many toxic gases are produced. Simultaneous combustion easily produces a large amount of smoke and dust, which pollutes the environment. Now the main way is to use raw coal For this screening, the raw coal with more impurities is filtered out to ensure the quality of the raw coal. The steps of multiple screening of raw ...

[0002] my country has always been a big country for mining and using coal. Coal is prone to produce toxic gases such as sulfur dioxide. As the country continues to increase its efforts to improve the environment, it is necessary to subdivide coal for use. Traditional coal screening equipment can only screen a single aperture. The raw coal cannot be further subdivided, resulting in the mixed combustion of a large amount of high-quality raw coal and raw coal containing more impurities. The combustion efficiency is low, and many toxic gases are produced. Simultaneous combustion easily produces a large amount of smoke and dust, which pollutes the environment. Now the main way is to use raw coal Carry out this screening and filter out the raw coal with more impurities to ensure the quality of the raw coal. The steps of multiple screening of raw coal are cumbersome and time-consuming, so a coal screening equipment is needed to solve the above problems
