Large steel plate coal house

Abstract

The invention relates to a large steel plate coal house which comprises a base, a bunker body and a coal bunker purging system. The base comprises a bottom board and a supporting structure arranged above the bottom board. The supporting structure comprises a bucket wall and a supporting column located on the inner side of the bucket wall, and a door opening is formed in the outer side face of the bucket wall. The bunker body is fixedly arranged above the base, at least two conveyor hoppers are arranged on the bottom face of the bunker body, and a weather enclosure, a dust collection device and a ventilation device are arranged on the top of the bunker body. The coal bunker purging system comprises an air source, a purging pipe, a control device and a monitoring device, one end of the purging pipe penetrates through the wall of the bunker body and stretches into an inner cavity of the bunker body, the other end of the purging pipe is communicated with the air source through an electromagnetic valve, the monitoring device comprises a methane sensor, the control device is electrically connected with the electromagnetic valve and the methane sensor, and the control device can open or close the electromagnetic valve according to data transmitted by the methane sensor. The large steel plate coal house is large in storage volume, good in environment protection property and high in site utilization rate, and storage, discharging and loading are integrated.

Description

technical field [0001] The invention relates to a storage device, in particular to a large steel plate coal storage. Background technique [0002] Coal storage facilities are important facilities in coal production systems such as coal mines, coal preparation plants, thermal power plants, ports, coal chemical plants, and coal transfer stations. The demand for coal transfer, storage and loading. With the development of the economy and the strengthening of environmental awareness, enterprises have higher and higher requirements for coal storage facilities. [0003] At present, coal storage facilities mainly include: open-air coal storage yards, dry coal sheds, hemispherical coal storage bunkers, silos, etc. The open-pit coal storage yard has the characteristics of low investment, simple construction, and flexible use. Its disadvantages are large coal storage loss, large floor space, and serious environmental pollution. , but still cannot completely eliminate the pollution o...

AI Technical Summary

Problems solved by technology

The open-pit coal storage yard has the characteristics of low investment, simple construction, and flexible use. Its disadvantages are large coal storage loss, large floor space, and serious environmental pollution. , but still cannot completely eliminate the pollution of coal dust to the atmosphere

The dry coal shed is a semi-enclosed coal storage yard formed by covering the open coal yard. It can prevent the coal from being drenched when it rains and pollutes the environment when the wind blows. It has the characteristics of large span and large coverage area. The disadvantage is that it needs to set up a separate The coal stacker has a large investment, and the rods of the reticulated shell are easy to corrode and bend, resulting in reduced safety

The hemispherical coal storage bunker is a closed coal storage yard composed of a spherical reticulated shell, a retaining wall and a concrete foundation. It has good environmental protection, large diameter, short construction period, and personnel can enter the storage yard for maintenance. The disadvantage is that it needs to set up stacking Material machine, high energy consumption, large floor area, small site utilization rate, large investment

The silo has the characteristics of small footprint and good environmental protection, but the current silos generally have shortcomings such as small reserves, large investment in concrete for the silo body, and accumulation of material at the bottom.
