Self-liquid-preparation concentration-adjustable anti-freezing dust-suppression spraying system of large rock dumping machine

Abstract

The invention belongs to the technical field of mine dust prevention, and particularly relates to a self-liquid-preparation concentration-adjustable anti-freezing dust-suppression spraying system of a large rock dumping machine. The invention discloses a self-prepared solution concentration-adjustable anti-freezing dust-suppression spraying system of a large rock dumping machine. The self-prepared solution concentration-adjustable anti-freezing dust-suppression spraying system comprises a quantitative CaCl2 preparation system, a multi-stage solution preparation system group, a spraying system and a control system, the quantitative CaCl2 batching system is mounted at the top of each single-stage solution preparation system of the multi-stage solution preparation system group and is connected with the single-stage solution preparation system through a feeding hole 211; the last discharge port 212 of the multi-stage solution preparation system group is connected with a liquid storage tank of the spraying system; a spraying system water pump of the spraying system is connected with a master controller of the control system, and a signal receiving end and a signal output end of the control system are connected with a sensor group and a plurality of controllers through wireless signals. The system has the advantages of being automatic in the whole process, high in efficiency, high in precision, capable of adjusting the solution concentration in time and capable of adapting to normal operation in various severe working environments.

Description

technical field [0001] The invention belongs to the technical field of mine dust prevention, and particularly relates to a large-scale rock-discharging machine self-preparing liquid and adjustable concentration anti-freezing and dust-suppressing spray system. Background technique [0002] Most of the open-pit mines in my country will use rock dumping machines to transfer ore in the production process. During the rock dumping process, a large amount of dust will be generated. With the flow of air, the dust will cause long-term and large-scale environmental pollution, which is not in line with national environmental protection. requirements, and will also have an impact on people's respiratory health. [0003] At present, in order to solve the problem of fugitive dust caused by the operation of rock excavators in open-pit mines, spraying water is mainly used to suppress dust. 2 solution. Because of CaCl 2 The aqueous solution can prevent freezing at low temperature, and the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a self-mixing liquid-adjustable concentration anti-freezing and dust-suppressing spray system for a large-scale rock discharger, which solves the problem of manual deployment of CaCl in the prior art. 2 The solution efficiency is low, the concentration cannot be adjusted in time according to the temperature change, and the amount of the solution cannot be accurately controlled, resulting in excess or shortage, etc.
