Description

Warehouse bottom dust suppression device for cement clinker Technical Field The utility model belongs to the technical field of bottom dust suppression of cement clinker, and particularly relates to a bottom dust suppression device of cement clinker. Background The cement clinker is an intermediate product in cement production, and a massive material formed by calcining raw materials such as limestone, clay and the like at high temperature is required to be stored in a large-scale material warehouse, so that the problem of dust flying caused by strong material fluidity and tiny particles in the discharging and transporting processes at the bottom of the cement clinker warehouse is solved, and the dust not only pollutes the environment and damages the health of workers, but also can cause raw material waste and potential safety hazard, so that corresponding dust suppression is required in the related operation production process. Most of common dust suppression devices are only provided with a single dust hood and related structures, however, dust is accumulated on the inner side surface of the dust hood after the dust hood is used for a long time, so that dust collection effect of the dust hood is gradually reduced, cleaning operations of related parts such as the dust hood are required to be carried out during intervals, dust in a cement silo bottom cannot be adsorbed continuously in the cleaning operation due to the single dust hood and related structures, production operation is interrupted, and dust dissipation in the process is possibly caused due to interruption of dust adsorption operation, so that actual dust suppression use is affected.
