Description

Technical Field

[0001] This utility model relates to the field of mine water treatment technology, specifically to a mine water purification sedimentation tank. Background Technology

[0002] Mine water is water that enters the mine through water channels created during the mining process. It is also an important unconventional water source and plays a vital role in alleviating water shortages and protecting the ecological environment. However, mine water usually contains a large amount of suspended solids, heavy metal ions and harmful impurities, and must be purified by sedimentation before it can be discharged or reused.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] However, traditional horizontal flow sedimentation tanks have low hydraulic load, making it difficult for fine particles to settle, resulting in low sedimentation efficiency. Furthermore, the sludge at the bottom of the tank is prone to hardening, requiring heavy manual cleaning and causing secondary pollution, and sludge removal from the bottom of the tank is also quite difficult. Utility Model Content

[0005] The purpose of this invention is to provide a mine water purification sedimentation tank to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mine water purification sedimentation tank, comprising a tank body, the interior of which is divided into a mixing tank and a separation tank, an inlet pipe is provided at the top of the rear side wall of the mixing tank, a dosing pipe is provided at the top of the side wall of the mixing tank, a nozzle is provided at the outlet of the dosing pipe, and an agitator is installed on the mixing tank;

[0007] An overflow outlet is provided at the top of the front side of the separation tank. An inclined plate is provided inside the separation tank. A sludge collection hopper is provided at the bottom of the tank body at the separation tank. The sludge collection hopper is connected to the sludge discharge trough through a sludge outlet at the bottom. A sludge discharge pipe is connected to the front end of the sludge discharge trough. The outlet end of the sludge discharge pipe is connected to the feed inlet of the sludge pump.

[0008] The stirring component includes a drive motor, and a shaft is mounted on the output end of the drive motor, with blades provided on the shaft.

[0009] More preferably, the bottom surface of the mixing tank is inclined, a partition is provided between the mixing tank and the separation tank, and the bottom of the partition between the mixing tank and the separation tank is through.

[0010] More preferably, the inner sidewall of the top of the mixing tank is provided with a connecting plate, and the stirring component is installed on the mixing tank through the connecting plate.

[0011] More preferably, the number of nozzles is two, and the two nozzles are symmetrically arranged on the front and rear sides of the stirring component.

[0012] More preferably, the number of blades is two, and the two blades are arranged perpendicularly along the shaft direction.

[0013] More preferably, there are several inclined plates, which are evenly distributed inside the separation tank.

[0014] More preferably, there are two mud collection hoppers, and both mud collection hoppers are connected to the mud discharge trough through mud discharge ports at the bottom.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The mine water is discharged into a mixing tank to fully mix and react with the reagents, and then discharged into a separation tank for sedimentation and filtration. The settled mine water is discharged from the outlet at the front end. This process can collect and filter impurities, suspended solids, and fine particles in the mine water, effectively separating impurities from the mine water and further improving sedimentation efficiency. The sludge accumulated in the mine water settles into the sludge collection hopper at the bottom of the tank, and then enters the sludge discharge trough from the sludge collection hopper. It is then pumped out by the sludge pump, which can remove and clean the sludge accumulated in the sludge collection hopper, achieving the effect of convenient cleaning of the mud and scale at the bottom of the tank.
