Problems solved by technology

[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 im

Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below in conjunction with the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention. Not all, based on this embodiment, other embodiments obtained by those skilled in the art without creative efforts are all within the protection scope of the present invention.

[0028] Such as Figure 1 to Figure 11 As shown, a coal screening equipment includes a bottom plate 1, and four circular vibrating screens 2 are distributed around the center of the bottom plate 1. Screens 3 with different apertures are distributed in the vibrating screen 2, and are installed on the bottom plate 1. A storage rack 4 for storing a plurality of screens 3, a conveying device 5 for transporting the screens 3 to the corresponding vibrating screen 2 is distr...

Abstract

The invention relates to coal screening equipment which comprises a bottom plate. Four circular vibrating screens are distributed around the center of the bottom plate, and screen nets with differentapertures are distributed in the vibrating screens. The coal screening equipment further comprises a storage frame installed on the bottom plate for storing the multiple screen nets. A conveying device for conveying the screen nets into the corresponding vibrating screens is distributed above the bottom plate, and the bottom plate is provided with a lifting mechanism which drives the storage frameto ascend and descend. Multi-aperture screening of raw coal is realized, repeated screening is not needed, screening steps are reduced, screening time is shortened, screen plates with different apertures are conveyed into corresponding vibrating screens through cooperation of the conveying device and the lifting mechanism, manual installation is not needed, the work intensity of workers is reduced, screening preparation time is shortened, and screening efficiency is enhanced.

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 ...
