Car tipper bottom layer water sprinkling system and control method

Abstract

The invention provides a car tipper bottom layer water sprinkling system and a control method. The car tipper bottom layer water sprinkling system comprises a main water supply pipe, branch water supply pipes and a control device; the main water supply pipe is used for supplying water; the branch water supply pipes are arranged between the main water supply pipe and feeding hoppers of a car tipperin a communicating mode and used for sprinkling water to the corresponding feeding hoppers, each feeding hopper corresponds to at least two branch water supply pipes, and a control valve is installedon each branch water supply pipe; and the control device is in signal connection with the control valves and is used for controlling only one branch water supply pipe to sprinkle water to the feedinghopper with unloaded materials located at the bottommost layer of a belt conveyer by controlling opening and closing of the corresponding control valve. According to the technical scheme, the sourceof the materials at the bottommost layer of the belt conveyer can be effectively judged, the condition that the materials are stuck to the upper surface of the belt conveyer after unloading is finished is effectively avoided by controlling the water sprinkling volume of the materials at the bottommost layer, and the running reliability of the belt conveyer is improved.

Description

technical field [0001] The invention relates to the field of control systems, in particular to a sprinkler system and a control method for the bottom of a dumper. Background technique [0002] The dumper system is a large-scale unloading equipment, which is used to dump the materials transported by the train to the lower hopper, and then transport the materials to the belt conveyor through the feeding device to realize the dumping and transshipment of the materials. During the material transfer process, small particles of coal dust and other materials will cause dust pollution. In order to reduce pollution, a common treatment method is to arrange a sprinkler system at the upper end of the feeder at the lower part of the funnel according to the characteristics of the dumper system. This treatment method can solve the problem of dust pollution. For the problem of dust in the feeder area, by increasing the water content of the coal, the dust suppression function in the whole pr...

Problems solved by technology

[0004] The purpose of the present invention is to at least partially solve the problem in the prior art that water is easy to accumulate on the surface of the belt conveyor to form ice or coal-water mixture, and reduce the impact of excessive watering on the operation of the belt conveyor and dumper system
