Problems solved by technology

When the trestle-type coal storage yard is working, the coal is directly unloaded by the mobile belt conveyor on the top, which will generate a lot of coal dust and cause environmental pollution in the entire coal storage yard.
In order to solve the serious over-limit problem of coal dust concentration in the coal storage yard, a sprinkler system is generally installed on the top of the coal storage yard to reduce dust with fog curtains. However, this system will cause high humidity in the entire coal storage shed and poor visibility, which will affect the work of workers. Moreover, the water consumption is large and maintenance is difficult; there are also coal storage yards that use telescopic chutes to reduce dust, but the chutes are severely worn and the dust removal effect is poor
[0003] In short, the existing dust suppression technologies generally have problems such as large water consumption, high operating costs, difficult maintenance, large dust range and poor dust removal effect.

Abstract

The invention relates to a dust falling system for trestle type coal unloading. According to the technical scheme, a movable water tank (5) is fixedly connected with a movable belt conveyor (1), the upper end of an upper moving cover (16) is fixed to a feeding port of a system platform (18), a lower moving cover (15) is located below the upper moving cover (16), and a synchronous lifting device (6) is connected with the lower moving cover (15) through a steel wire rope (7). An upper annular spraying device (8) is mounted on the inner wall of the upper moving cover (16). A dust sensor (9), a first layer lower annular spraying device (14), a radar level meter (11), a second layer lower annular spraying device (12) and a third layer lower annular spraying device (13) are sequentially mounted on the inner wall of the lower moving cover (15) from top to bottom. A high pressure water pump (4) is connected with the upper annular spraying device (8), the first layer lower annular spraying device (14), the second layer lower annular spraying device (12) and the third layer lower annular spraying device (13) respectively through high pressure water pipes (3). The dust falling system for trestle type coal unloading has the advantages of being small in water consumption, low in operation cost, good in dust removal effect and easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of dust suppression systems. In particular, it relates to a dust suppression system for trestle unloading coal. Background technique [0002] Due to the flow of materials, on-site loading and unloading operations, and wind disturbances in the coal storage yard of coal enterprises, coal dust is diffused in the air, and the coal dust suspended in the air has the risk of explosion, and the loss of coal dust will cause waste of resources and pollute the surrounding environment. Because the trestle-type coal storage yard has the advantages of simple storage system and low investment, it is currently used by many coal storage yards. When the trestle-type coal storage yard is working, the coal is directly unloaded by the mobile belt conveyor on the top, which will generate a lot of coal dust and cause environmental pollution in the entire coal storage yard. In order to solve the serious over-limit problem of coa...
