Abstract
Description
技术领域technical field

背景技术Background technique
原煤料斗结拱一直是生产中常见且极难解决的老大难问题，长期以来在煤炭储运、燃煤发电厂、冶金等领域频繁出现，给正常生产和检修带来很大困难，也使得生产成本不断加大。料斗结堵是物料压实结拱而造成的，其主要原因：温度低，散装物料流动性差；物料露天存放、雨水和洒水喷淋使物料湿度加大易导致压实结拱；料斗的倒锥形结构，也是料斗结拱的可能性增加；料斗中结拱未能及时发现和处理，导致越压越实，难于处理等等原因。现有的疏通装置疏通效率低，在实际运行中仍常出现料斗结拱的现象。Arching of raw coal hoppers has always been a common and extremely difficult problem in production. Costs keep increasing. The clogging of the hopper is caused by the compaction and arching of materials. The main reasons are: low temperature and poor fluidity of bulk materials; open storage of materials, rain and water spraying increase the humidity of materials and easily lead to compaction and arching; the inverted cone of the hopper The shape structure also increases the possibility of arching in the hopper; the arching in the hopper cannot be detected and dealt with in time, resulting in more compaction and difficulty in handling. The dredging efficiency of the existing dredging device is low, and the phenomenon of hopper arching still often occurs in actual operation.
