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 particularly relates to a mobile type automatic spraying dust-settling system for a trestle type coal storage yard. According to the technical scheme, a mobile type water tank (5) is fixedly connected with a mobile type belt conveyor (1) through a horizontal connecting piece (2), the upper end of an upper moving cover (15) is concentrically fixed at a feeding opening of a system platform (17), the upper end and the lower end of a telescopic moving cover (11) are correspondingly connected with an upper moving cover (15) and a lower moving cover (12), synchronous lifting devices (6) are connected with the lower moving cover (12) through steel wire ropes (7) thereof, a dust sensor (8) and an upper annular spraying device (10) are arranged on the inner wall of the upper moving cover (15), a lower annular spraying device (14) and a radar level meter (13) are arranged on the inner wall of the lower moving cover (12), high-pressure water pumps (4) are connected with the upper annular spraying device (10) and the lower annular spraying device (14) respectively through high-pressure water pipes (3). The mobile type automatic spraying dust-settling system has the advantages of being small in water consumption, low in operation cost, good in dust removing effect and easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of mobile automatic spray dust suppression system. In particular, it relates to a mobile automatic spray dust suppression system used in trestle-type coal storage yards. 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....
