Description

Coal washery is with high pressure washing cinder doffer Technical Field The utility model relates to the technical field of cinder treatment, in particular to a cinder blanking device for high-pressure flushing in a coal washery. Background In the coal washing process, the cleaning of the cinder dropping hopper is a key link, and especially when cinder falls into the collecting hopper from a sieving machine or other processing equipment, the cinder may be accumulated or agglomerated on the inclined wall of the dropping hopper due to the particle characteristics, the moisture content and the impact in the conveying process of the cinder. The blanking hopper is generally erected above the cinder treatment equipment and is used for receiving and collecting cinder screened or treated by the screening machine. The structure ensures that the cinder is easily influenced by the wet inclined wall in the falling process, particularly, more fine particles in the cinder are easily adsorbed on the wet inclined wall, and a layer of coherent slag skin is formed. Once the material cannot be removed in time, the material can be thickened gradually, and the smooth falling of the material is affected. The accumulation or caking phenomenon not only can obstruct the normal flow of coal cinder, but also can cause the problems of equipment blockage, shutdown and the like, increase the operation risk, aggravate the pressure on subsequent conveying equipment and influence the stability and the continuity of the whole coal washing system. In the prior art, in order to solve the problems of adhesion and caking of coal cinder of a blanking hopper, a manual high-pressure water gun is generally adopted for cleaning. Operators need to enter equipment or stand on an operation platform, and the high-pressure water gun is held by the hands to wash the parts with serious accumulation. In order to ensure safety, workers generally need to wear protective clothing, waterproof gloves, protective masks and other equipment, and flexibly adjust water pressure and spray angles according to blocking positions so as to achieve a thorough cleaning effect. The manual cleaning mode has a plurality of defects. Firstly, the labor intensity in the cleaning process is high, fatigue and even injury of workers are easily caused by long-time operation, secondly, the manual operation efficiency is low, especially when the large-scale blanking hopper or the slagging range is wide, the cooperative operation of a plurality of workers is often required, time and labor are consumed, and thirdly, the consistency of the cleaning quality is difficult to ensure due to the subjectivity of the operation and the large difference of the treatment modes and effects of different operators.
