Description

Technical Field

[0001] The utility model relates to the field of coal transportation, in particular to a dust suppression device for coal transportation. Background Art

[0002] Coal conveying device refers to the device for transporting coal. Its installation forms can be divided into two types: coal conveying corridor and coal conveying trestle. Coal conveying corridor is similar to a trench, generally an underground or semi-underground concrete structure, with the conveyor installed in the corridor, and the coal is transported through the corridor by a conveyor; coal conveying trestle is generally mainly steel structure, overhead, some closed and some not, with conveyors installed on it to transport coal. Its transportation methods include belt conveying, pneumatic conveying and pipeline conveying, among which belt conveying is the most widely used:

[0003] Compared with the dust suppression device for coal transportation of a thermal power unit in CN218485549U, the dust generated by the coal conveyor is sucked into the trapezoidal working box by using a negative pressure fan and a conical air delivery pipe for filtering and collection. On the one hand, the dust in the sealed box can be treated by the atomized water flow flowing out of the water storage tank to prevent the dust from flying randomly, which effectively improves the environmental protection performance. The filter plate can filter the dust falling into the trapezoidal working box, and after filtering, the dust can flow downward into the dust collecting trough plate for collection, which is convenient for quick dumping of the dust, and also convenient for cleaning the filter plate and the dust collecting trough plate after taking out the push-pull positioning plug plate. However, there are still certain problems, and the specific problems are as follows;
