Mining pure water preparation device

Abstract

The invention provides a mining pure water preparation device. The mining pure water preparation device comprises: a chemical storage box used for storing chemicals; an intermediate water tank used for containing mine water; a chemical dosing device, wherein the inlet end of the chemical dosing device is connected with the chemical storage box, and the outlet end of the chemical dosing device is connected with the intermediate water tank to convey chemicals in the chemical storage box into the intermediate water tank; and a chemical liquid concentration sensor connected with the outlet end of the intermediate water tank and used for detecting the chemical liquid concentration of the liquid output by the intermediate water tank, wherein the chemical dosing device is electrically connected with the chemical liquid concentration sensor and used for being opened or closed according to the detection result of the chemical liquid concentration sensor. According to the mining pure water preparation device provided by the invention, the chemical liquid concentration sensor is arranged at the outlet end of the intermediate water tank, so that the concentration of a chemical in water can be detected, and the opening or closing of the chemical dosing device is controlled according to the detection result of the chemical concentration, and the effects of treating mine water and reducing the cost of producing pure water are considered.

Description

technical field [0001] The invention relates to the field of mine water treatment equipment, in particular to a mine pure water preparation device. Background technique [0002] At present, the pure water medium hydraulic system of the fully mechanized mining face uses pure water as the power medium of the hydraulic support. The pure water medium has the advantages of flame retardancy, cleanliness, and low cost. Improve production efficiency, extend the life of hydraulic components, and reduce spare parts loss. The mine pure water preparation device processes the underground production water of the coal mine into pure water that meets the requirements of the relevant national and industry standards through the pure water process. It is the core equipment of the pure water medium hydraulic system of the fully mechanized mining face. Among them, the process flow of the pure water preparation device includes pretreatment, ultrafiltration, reverse osmosis, electrodeionization, ...
