Dust suppression spraying device for railway coal transportation

Abstract

The invention relates to a railway coal transportation and dust suppression spraying device. A spraying barrel of the device comprises an outer barrel, an inner barrel and a center infusion tube; the outer barrel is a fixed barrel, the center infusion tube penetrates an outer barrel tube to be fixed to the outer barrel, and the inner barrel is assembled on the center infusion tube through a transmission shaft in a sleeving manner; a liquid inlet of the center infusion tube is connected with a liquid feeding pipe, a spraying nozzle is installed on the center infusion tube, and the outer barrel and the inner barrel are each provided with spraying holes corresponding to nozzles in position; and a liquid return discharging opening communicated with a liquid return pipe is formed in one side end, provided with the outer barrel, of the spraying barrel. The device is provided with a photoelectric inductive switch for detecting a car coupler between a train carriage and a carriage and a shielding mechanism matched with the photoelectric inductive switch to move, and the shielding mechanism controls the inner barrel to rotate to stagger the positions of the spraying holes in the inner barrel and the positions of spraying holes in the outer barrel so as to block a spraying opening of the outer barrel. According to the railway coal transportation and dust suppression spraying device, a dust suppressant cannot be sprayed to the car coupler and the ground between the carriages, liquid in the pipe cannot flow out from the spraying opening after spraying is completed, and the spraying amount can be accurately controlled.

Description

technical field [0001] The invention relates to a spraying device, in particular to a coal dust suppression spraying device used for railway coal transportation. Background technique [0002] Railway coal transportation is generally carried in open carriages. Due to the influence of airflow and wind during train transportation, the coal powder on the surface is flying everywhere, resulting in the loss of coal resources and environmental pollution. [0003] The current measure to control the flying of pulverized coal is to spray dust suppressants on the trains in transit, but the control methods and functions of the existing spraying devices are relatively backward, and there are the following problems: [0004] (1) From entering the spraying state until the train passes, the spraying device is always in the spraying state, so that part of the dust suppressant is sprayed on the coupler between the carriages and the ground, so that there is fluid on the rails. In hot weather, ...
