Abstract

The invention relates to a pneumatic dosing device for mine wastewater and a processing system for the mine wastewater. The pneumatic dosing device for the mine wastewater comprises a tank body for loading a solution; the tank body is provided with a solution inlet, a solution outlet, and an air inlet for being connected to mine compressed air; the solution outlet is disposed at the bottom of the tank body; the solution outlet is connected to a solution-discharging tube for discharging the solution in the tank body to a wastewater pool; the outlet of the solution-discharging tube is higher than a liquid surface in the tank body when the pneumatic dosing device is in use. Since the dosing device takes use of the mine compressed air as a power, the power source has the advantages of stability, reliability, safety and convenience. Therefore, the dosing device is not liable to be damaged, is small in workload required for maintenance, is in no need of consuming electric energy, can brings about significant economic benefits, and effectively overcomes the problems of high cost for use and maintenance in a conventional dosing device. Besides, the dosing device has no noise in work and can provide a good work environment for workers.

Description

technical field [0001] The invention relates to a mine wastewater pneumatic dosing device and a mine wastewater treatment system. Background technique [0002] During the purification treatment of coal mine wastewater, chemicals need to be added to it. The dosing device used in the prior art is a dosing pump, which is connected to the mine wastewater pool through a dosing pipeline. When in use, the dosing pump can output the medicine from the medicine source and enter the mine waste water pool through the dosing pipeline. . However, when the dosing pump is in use, there are the following problems: 1. The noise of the dosing pump is relatively large, which will affect the working environment on site; The dosing pipeline is prone to blockage; 3. It needs to consume a lot of electric energy, and the use cost is high; 4. The dosing pump is easy to be damaged and requires regular maintenance, which will consume a lot of maintenance costs every year. [0003] The reason why the...
