Description
Technical Field
The utility model relates to a dome coal storage bunker presses down dirt technical field, in particular to automatic dust device is used in coal bunker.
Background
Because of environmental protection, coal yards all need to be sealed, but there are some following problems in the sealed coal bunker: firstly, the coal dust is easy to explode after being accumulated to a certain degree, and the destructive power is huge, so that the dust prevention and reduction problem is faced, and in addition, along with the accumulation of a coal bed, spontaneous combustion caused by high local temperature can be generated, and attention should be paid; secondly, workers are in health problems, and because most of closed coal bunkers do not achieve mechanical automation completely, the participation of workers cannot be avoided, wherein a loader driver, a coal pulling car driver, field maintenance personnel and the like need to work in the closed coal bunkers, and the lung diseases of the workers are easily caused by coal dust; thirdly, the environmental impact is that although the coal bunker is closed, the inlet and the outlet of the coal bunker are generally opened for the convenience of automobile coal transportation, but the dry wind force in northern weather is large, convection is formed through the inlet and the outlet of the coal bunker, so that the pulverized coal in the coal bunker can diffuse through the inlet and the outlet, and the surrounding environment of the inlet and the outlet of the coal bunker is affected.
SUMMERY OF THE UTILITY MODEL
To the not enough with above-mentioned background art, the utility model provides a coal bunker is with automatic dust device.
The utility model adopts the technical scheme as follows: the utility model provides a coal bunker is with automatic dust device, the key lies in: the coal unloading device comprises a bin body and a plurality of cyclone dust collectors, wherein a travelling crane channel and a plurality of coal unloading areas are arranged in the bin body, the coal unloading areas are all located on one side of the travelling crane channel and are uniformly distributed along the length direction of the travelling crane channel, discharge ports are formed in the side wall of the bin body and are located in the coal unloading areas, coal sweeping assemblies are arranged in the coal unloading areas, the cyclone dust collectors correspond to the coal unloading areas one by one, air inlets of the cyclone dust collectors are communicated with pipelines at the top of the bin body, and dust falling ports of the cyclone dust collectors are communicated with pipelines close to the coal unloading areas.
Preferably, a plurality of groups of dry fog spraying devices are arranged in the bin body, and each dry fog spraying device is arranged above each coal unloading area. The effect of this scheme is that can reduce the dust volume in each unloading coal district.
Preferably, the bottom surface of the coal unloading area is an inclined surface, the inclined surface extends upwards to the travelling crane channel, and the inclined surface extends downwards to the lower edge of the discharge hole. The effect of this scheme is that can make the automatic discharge gate gathering of coal cinder in unloading coal district.
Preferably, the coal sweeping assembly comprises a coal sweeping motor fixedly arranged on the ground of the bin body, the coal sweeping motor is close to the coal unloading area, an output shaft of the coal sweeping motor vertically and upwards extends out of a fixedly connected horizontal rod, a connecting rod is movably arranged on the horizontal rod in a penetrating mode, the upper end of the adjacent connecting rod is hinged through a horizontal rod, and the lower end of each connecting rod is connected with a scraping blade. The effect of this scheme is along with the horizontal rod rotates, both can be with the coal cinder income of driving passageway unload the coal district, can become flexible unload the coal cinder in coal district again.
Preferably, the lower edge of the scraper is in contact with the ground of the bin body.
Preferably, a plurality of backflow ports are formed in the bin body, and the backflow ports are located above the discharge port and are close to the discharge port.
Has the advantages that: compared with the prior art, the utility model provides a pair of automatic dust device is used in coal bunker, through dividing the operation region in the coal bunker into driving passageway and a plurality of district of unloading coal, and sweep the coal subassembly then both can collect the coal cinder of scattering at driving passageway in the district of unloading coal, and can be not hard up to the coal cinder in district of unloading coal, prevent to harden, it reduces partial dust to press down dirt spray set through dry fog, will not send into again the district of unloading coal after retrieving with the dust that the spraying combines through cyclone, to carrying out all-round dust removal in the coal bunker, and practiced thrift the buggy resource, environmental pollution around the coal bunker is imported and exported greatly has been alleviated.
