Dry separator feeding device and feeding method

Abstract

The invention discloses a dry separator feeding device and feeding method. The dry separator feeding device comprises a grading sieve, and further comprises a reversed loader and a vibrating distributing device. A feeding opening of the reversed loader communicates with a discharging opening of the grading sieve. A feeding opening of the vibration distributing device communicates with a discharging opening of the reversed loader. A discharging opening of the vibrating distributing device is used for communicating with a feeding opening of a dry separator. The dry separator feeding method is used for feeding by the dry separator feeding device. By means of the dry separator feeding device and feeding method, the arrangement flexibility of the grading sieve and dry separator is improved, rawcoal is uniformly laid on the dry separator, and the sorting precision and sorting effect of the dry separator are improved.

Description

technical field [0001] The invention relates to the technical field of coal dry separation, in particular to a dry separation machine feeding device and a feeding method. Background technique [0002] Dry separator is a new type of coal separation equipment, which can divide lump coal into clean coal, medium coal, and gangue, remove impurities in lump coal, and improve the quality of lump coal. [0003] In the prior art, the dry separator is directly connected with the grading sieve, and after the raw coal is screened by the grading sieve, the lump coal on the sieve directly enters the dry separator. The inventor found in the process of realizing the invention that the above-mentioned lump coal directly enters the dry separator from the grading sieve and has the following disadvantages: the first, the outlet of the grading sieve is directly connected with the inlet of the dry separator, requiring the grading sieve The discharge port of the dry separator needs to match the f...

Problems solved by technology

The inventor found in the process of realizing the invention that the above-mentioned lump coal directly enters the dry separator from the grading sieve and has the following disadvantages: the first, the outlet of the grading sieve is directly connected with the inlet of the dry separator, requiring the grading sieve The discharge port of the dry separator needs to match the feed port of the dry separator, and the height difference between the discharge port of the grading sieve and the feed port of the dry separator should not be too large. High, poor flexibility; second, when the amount of coal on the grading screen fluctuates greatly instantaneously, a large amount of lump coal instantly enters the dry separator, resulting in serious superimposition of lump coal on the belt surface of the dry separator, which cannot be evenly spread , which greatly affects the subsequent sorting accuracy and sorting effect of the dry separator
