Control system of spraying device of open coal car

Abstract

The invention discloses a control system of a spraying device of an open coal car. The control system comprises control equipment, liquid supplying equipment, a spraying device and a train speed sensor, wherein the control equipment mainly comprises a programmable controller and a frequency converter; the liquid supplying equipment comprises liquid supplement equipment, stirring equipment and conveying equipment and is used for stirring, blending, diluting and conveying a coal dust suppressant; the spraying device is used for uniformly spraying the coal dust suppressant onto coal in the running coal car; and the train speed sensor is used for measuring the speed of a running train. Because the acquired train speed data is transmitted to the programmable controller through the train speed sensor and the frequency converter of the control equipment adjusts the opening, closing and rotation speed of a spraying pump of the conveying equipment according to the processing result of the programmable controller of the control equipment, the control system can control the spraying amount of the coal dust suppressant in real time, avoids waste of the dust suppressant and saves cost.

Description

technical field [0001] The invention relates to a control system of an open coal car spraying device. Background technique [0002] In the process of coal storage and transportation, due to wind and other reasons, coal dust will be lost with the wind, throwing dust, wasting a lot of precious resources; coal dust is acidic, and after being thrown, it will adhere to buildings such as stations and civil facilities along the line. Objects and crops have seriously affected the health of the people along the railway line, and at the same time caused damage to the growth of crops along the line. Coal dust also seriously polluted the ballast bed of the line in the tunnel and aggravated its compaction. In areas with serious pollution, coal dust has buried fasteners, sleeper boards, etc., which has brought considerable difficulties to the daily maintenance and repair of the public works department, and increased the workload. At the same time, it has certain damage to rails and faste...

AI Technical Summary

Problems solved by technology

[0008] The present invention designs a control system of an open coal car sprinkler, which mainly solves the following technical problems: (1) the speed of the existing coal transport train passing through the coal dust suppressant spray device is different, and the coal dust suppressant The spraying device cannot control and adjust the speed and amount of spraying coal dust suppressant in time, nor can it control the start of spraying and stop collection, resulting in poor spraying effect and waste of dust suppressant
