A vibrating coal separator

Abstract

The invention discloses a vibrating coal separator, which comprises a frame main body, on which a vibrating sieve bed arranged obliquely is installed via a spring damping seat, a vibrating screen mesh is fixed on the vibrating sieve bed, and a vibrating sieve bed is fixed on the vibrating sieve bed The end of the vibrating screen is provided with a material guide plate docked with the vibrating screen. The vibrating screen bed is provided with an anti-blocking and beating mechanism at the bottom of the vibrating screen for beating the bottom of the vibrating screen. The swing flushing mechanism of the net, the anti-blocking and beating mechanism includes a positioning frame set on the rotating shaft at the bottom of the vibrating screen, and a plurality of arc-shaped beating rods are hinged on the rotating shaft, and the arc-shaped beating rod and the rotating shaft A compression spring is hinged between them, and the vibrating sieve bed is provided with a vibration exciter. The invention has the characteristics of good coal preparation effect and good anti-blocking effect, and can effectively suppress the dust in the vibration screening process of the vibrating screen, thereby greatly improving the coal preparation effect of the coal separator.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a vibrating coal separator. Background technique [0002] my country has abundant coal resources and low coal prices. In recent years, comprehensive utilization power stations mainly burning low-quality coal have risen rapidly in China. Coal ore and coal slime as the main fuel are usually sticky, wet, dirty, and miscellaneous. , The coal handling system generally has the phenomenon of screen blockage, low screening efficiency, large crusher wear, and high energy consumption. Coal preparation machines usually use vibrating screens to separate and screen coal, and the screens are easily blocked by coal slime or other impurities. , the coal separator that is blocked by the screen will lose its normal function. At present, there is no effective solution to this problem, and when the raw coal is relatively dry, it is easy to produce a large amount of ash under the struggling screeni...

At present, there is no effective solution to this problem, and when the raw coal is relatively dry, it is easy to produce a large amount of ash under the struggling screening of the vibrating screen. The surrounding working environment causes pollution and causes irreversible damage to the arc system of the staff
