AI Technical Summary

Technical Problem

The existing dust suppression system on coal trains is fixed in its installation location and cannot adapt to the differences in the size of the carriages, resulting in incomplete dust suppression spraying and some dust suppressant dissipating in the air, thus failing to fully exert its dust suppression effect.

Method used

A spraying device was designed, comprising an installation frame, support columns, pipes, nozzles, and an adjustable connection structure. The height of the spraying device can be adjusted by the cooperation of sliders, chutes, and clamping bolts, ensuring that the dust suppressant covers the coal in the car and preventing the dust suppressant from dissipating.

Benefits of technology

The system allows for flexible adjustment of the spray device position based on the size of the carriage, ensuring comprehensive coverage of the dust suppressant, avoiding waste of the dust suppressant, and improving the dust suppression effect.

Abstract

The utility model belongs to the technical field of spraying devices, and particularly relates to a dust suppressant spraying device for coal transportation trains, which comprises two symmetrically arranged mounting frames. Three support columns are connected between the two mounting frames, and the three support columns are in a "pin" shape. A pipeline is connected between the two mounting frames, the bottom end of the pipeline is connected with a nozzle, one end of the pipeline is connected with a connecting hose, a connecting column is connected to the outer side wall of the mounting frame, and a docking column is connected to the top end of the connecting column. Through the cooperation among the connecting column, the docking column, the adjusting sleeve, the sliding groove, the sliding block and the extrusion bolt, the height of the pipeline in the mounting frame can be adjusted, so that the position of the spraying device can be flexibly adjusted according to the carriage size of the coal transportation train, ensuring that the atomized dust suppressant sprayed can comprehensively and effectively cover the coal in the carriage, avoiding partial dissipation of the dust suppressant in the air, and thus fully exerting the dust suppression effect.
