Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal mine water purification, in particular to a metal mine water purification device. BACKGROUND

[0002] In the field of metal mine exploitation technology, mine water is the core water body produced in the mining operation. It generally contains suspended particles, soluble metal ions and other impurities due to contact with ore bodies and surrounding rocks. If it is not purified and directly discharged, it will destroy the colloidal structure of the surrounding soil, pollute the surface and underground water system. If it is purified and reused in mining dust removal, equipment cooling and other links, it can not only reduce the dependence of mines on fresh water resources, but also reduce pollutant emissions. It is the key technical direction to achieve "water resource recycling" in the current green mine construction, and it is also the core research field of mine environmental protection treatment.

[0003] At present, for the purification needs of large flow metal mine water, the mainstream treatment scheme in the prior art is a segmented treatment process of a horizontal flow reaction tank, a rectangular sedimentation tank and an independent filter tank. The operation process and structure design of the process are as follows: first, the large flow mine water is transported to the horizontal flow reaction tank by the lifting pump. A plurality of paddle type mixers are arranged in the reaction tank along the water flow direction. At the same time, flocculating agent (such as polyaluminum chloride) is added to the tank by the dosing pump. With the rotation of the mixer, the agent and the mine water are preliminarily mixed to promote the formation of small flocs in the suspended particles in the water. Then, the mine water containing flocs slowly flows into the rectangular sedimentation tank along the flow channel of the reaction tank. The sedimentation tank adopts a long strip structure. The length of the tank body usually needs to reach 20-30 meters to ensure that the residence time of the water body in the tank is not less than 30 minutes. The principle of gravity sedimentation is used to make the flocculated particles gradually settle to the bottom of the tank. A mud scraper is arranged at the bottom of the tank to regularly scrape the sediment to the sludge discharge port. Finally, the supernatant in the upper layer of the sedimentation tank is collected through the overflow tank and then transported to the independent sand filter tank through the pipeline. The filter material layer is used to filter and remove the remaining small flocs and impurities in the water body. Finally, the water body reaches the reuse standard.

[0032] Specifically, the conical guide plate 12 can guide the flocs to slide along the inclined surface to the central outlet, and then the flocs are discharged to the tailings pond through the underflow discharge system 4 connected with the outlet. The flow divider 15 at the top end of the fixed column 13 is used to uniformly distribute the fluid flowing from the central reaction cylinder 7 into the barrel body 1. If the fluid directly impacts the bottom end vertically, the settled flocs are easily disturbed, causing the flocs to be dispersed into the water body again, which affects the solid-liquid separation effect.

The fluid flows to the bottom end of the cylinder 1 under the guidance of the conical flow guide 12, and part of the fluid is guided by the flow guide groove 14 at the bottom end of the fixed column 13. The flocs are quickly settled under the converging effect of the conical flow guide 12. The ultrasonic liquid level meter in the cylinder 1 monitors the liquid level in real time, and the bottom observation window checks the accumulation. Finally, the settled flocs enter the underflow discharge system 4 through the outlet of the conical flow guide 12 for discharge, the clean water body rises and is filtered through the inclined pipe filtration system 6, and then flows out from the water outlet. The turbidity meter at the water outlet detects the purification effect, the air slurry discharge system 2 sweeps the wall-hanging sediment at the bottom to make it enter the underflow discharge system 4 through the conical flow guide 12, and the spiral staircase 3 on the outer wall of the cylinder 1 and the maintenance platform 5 on the upper surface facilitate equipment maintenance.

[0034] While the embodiments of the application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
