Problems solved by technology
[0003] The object of the present invention is to provide a spiral rotary screening device. Since the screen body is designed as a spiral structure, and the outer surface of the support wheel is designed as a tooth structure, when the screen body runs on the support wheel, the spiral The sieve body is always in a vibrating state; in order to further prevent the viscous material from clogging the sieve holes, an elastic cleaning mechanism and a heavy hammer vibration cleaning mechanism are designed to solve the problem of adhesion and blockage of the sieve body

The invention provides a spiral rotary screening device which is provided with a stand, wherein an elastic body is arranged in the stand; the upper end of the elastic body is positioned at the bottom of a feed opening; a vibration source is arranged at the position on the outer wall of the feed opening, which is close to a screen body; two support riding wheels are respectively and fixedly arranged in two sides at the front end of the stand; a speed reducer is arranged at the rear end of the stand; a pinion is arranged on a main shaft of the speed reducer and is meshed with a gear of a bearing casing; the other end of the screen body is supported by the two support riding wheels; the screen body is formed by winding a strip-shaped steel plate into hollow spiral body type screen pieces; the space between every two screening pieces on the screen body is of a circular cage shape formed by equidistantly and uniformly arraying; and impact blocks are equidistantly arranged on the outer wall at the middle of the screen body. The spiral rotary screening device disclosed by the invention has the advantages of simple structure, high screening efficiency, reduced fault rate of equipment and reduced energy consumption; and the problem that the blocking easily occurs when materials are screened by a screen body can be solved.
Description
Technical field [0001] The invention relates to a screening device of a coal material conveying system, in particular to a spiral rotary screening device used in a coal screening system. Background technique [0002] In the screening devices of coal material conveying systems in metallurgical and power generation enterprises, coal screening equipment includes vibrating screens, roller screens and other forms of screening equipment. The vibrating screen covers a large area, has low efficiency and high power consumption. Can not be used in large coal storage occasions; while the roller screen has defects such as easy to be entangled by straw ropes, cloth impurities, easy to jam shafts, adhesions, high power consumption, and high failure rate. Especially when the above-mentioned equipment screens materials with high humidity, large impurities and high viscosity, there are disadvantages of low screening efficiency and high failure rate. Summary of the invention [0003] The purpose o...
