A multi-point well water coagulation and settlement device based on micro-magnetic coagulation technology

Abstract

The invention discloses a multi-point well water coagulation and settlement device based on micro-magnetic coagulation technology. There is a machine head that can move along the X-axis and Z-axis on the top. The coagulant metering pump and the magnetic suspension metering pump are installed at the lower end of the machine head. There is a rotating motor under the machine head. The rotating motor is connected through the lower end of the steering transmission mechanism. On the outer edge of the turntable, there are several equally divided feeding slots, the feeding slots are connected with paddles, the front side of the turntable is equipped with an electromagnet, the slag discharge chamber on the frame at the end of the tank, and the The slag scraping mechanism in the slag discharge chamber. The magnetic separation mechanism of the invention integrates stirring, dosing and magnetic adsorption, has a high degree of integration, and can quickly and efficiently coagulate, settle and magnetically separate mine water.

Description

technical field [0001] The invention belongs to the technical field of coal mine water treatment, and in particular relates to a multi-point well water coagulation and sedimentation device based on micro-magnetic coagulation technology. Background technique [0002] Mine water is composed of underground water gushing generated in the process of coal mining, dust-proof water sprinkler in underground mining production, equipment cooling and drainage, etc. It mainly contains coal powder and rock powder, and has the characteristics of high concentration of suspended matter and small particles that are difficult to settle. . Therefore, the discharge of mine water not only pollutes the environment, but also causes a lot of waste of limited water resources and coal powder, [0003] Suspended matter in mine water is mostly a composite of organic matter (coal powder) and inorganic matter (rock powder), and these suspended matter itself is non-magnetic. Therefore, non-magnetic suspen...

Problems solved by technology

[0004] At present, my country's mine water purification treatment and utilization system basically pumps water from underground to the ground and then uses conventional sedimentation technology for treatment. Although this technology has a certain effect on removing suspended solids in mine water, the process occupies an area of The area is large, the investment is large, the operating cost is high, and the amount of chemicals and magnetic species that need to be added is also large. This treatment method will greatly increase the treatment cost of mine water.
