Vertical cylinder type vibration coal and gangue separator

Abstract

The invention provides a vertical cylinder type vibration coal and gangue separator. The coal and gangue separator comprises a vertical cylinder body, a rotor shaft, a broken rotor, a material outlet, a feeding device and a vibration sieve; the rotor shaft is arranged in the cylinder body in a manner that the rotor shaft is coaxial with the cylinder body, and driven by a power source; the broken rotor is arranged on the rotor shaft and consists of a plurality of layers of impact bars arranged at the periphery of the rotor shaft; the material outlet is formed at the bottom of the cylinder body; the feeding device is arranged on the top of the cylinder body; the vibration sieve is arranged below the material outlet; the vibration sieve comprises a first stander, a middle stander and a second stander which are arranged on a base, and a sieve face obliquely arranged on the standers; the first stander and the second stander are hinged below the front end and the rear end of the sieve face; the middle stander is arranged below the middle part of the sieve face through a vibration shaft; the vibration shaft is combined with a vibration sieve motor through a shaft joint; the sieve face consists of a plurality of fracturing blades and a plurality of grate bars; the fracturing blades are fixed on the grate bars to form the vibration sieve face; and a gap between every two adjacent grate bars forms a sieve hole.

Description

technical field [0001] The invention relates to a vertical cylinder vibrating coal and gangue separator, which belongs to machinery and is suitable for separating raw coal and gangue, especially for separating raw coal and gangue after underground mining. Background technique [0002] In modern coal mining operations, comprehensive mechanized coal mining has been widely used. Although fully mechanized mining can greatly increase coal production, it also brings about the problem of how to deal with large lumps of raw coal underground. Coal contains a large amount of gangue, and some mines even have large lumps of raw coal larger than 1m in production. During the transportation process, coal flow lines are often blocked or even equipment is broken, which has become a problem that plagues mine safety production. According to the literature published at home and abroad, there is no recognized and mature solution to this problem in the current on-site production. In most mines, t...

Problems solved by technology

[0006] But this kind of horizontal selective crusher has more disadvantages

First of all, the larger the diameter of the body, the greater the processing capacity, and the rotation of the huge body consumes more energy, and more energy needs to be consumed when there is a rotor; secondly, the processing capacity is limited, because the horizontal selective crusher only It can feed materials from one side and discharge sundries and gangue from the other side, regardless of whether there is an angle between the machine body and the horizontal rotor shaft, its processing capacity is limited by the way the materials move

Enlarging the diameter of the cylinder can certainly increase the processing capacity, but it also increases the cost and difficulty of manufacturing, and the body is bulky, and the power consumption will also increase exponentially; third, the cylinder of some selective crushers adopts chain transmission. In this way, the power is transmitted from one end, and the chain transmission system makes the body suffer from a large torque and a lot of noise

The larger the diameter of the drum body, the more difficult it is to reinforce the large sprocket; Fourth, the horizontal selective crusher has more body parts and a complex structure, which increases the difficulty of manufacturing and maintenance
