Multi-point dispensing well water coagulating sedimentation device based on micro-magnetic coagulation technology

Abstract

The invention discloses a multi-point dispensing well water coagulating sedimentation device based on a micro-magnetic coagulation technology. The device comprises a frame, a water tank and a sedimentation tank which are arranged on the frame and a gantry frame arranged behind the frame, the crossbeam of the gantry frame is provided with a machine head capable of moving along the X-axis and the Z-axis, a coagulant metering pump and a magnetic suspension metering pump are arranged at the lower end of the machine head, a rotating motor is arranged below the machine head, the rotating motor rotates a rotating disc, connected to the rotating rotor, through the lower end of a steering transmission mechanism, the outer edge of the rotating disc is provided with a plurality of equally divided feeding grooves, the feeding grooves are connected with blades, and an electromagnetic disc, a residue discharge chamber located on the frame at one side of the end of the water tank, and a residue scraping mechanism located in the residue discharge chamber are arranged in front of the rotating disc. The device has the advantages of integration of stirring, reagent feeding and magnetic adsorption through magnetic separation mechanism, high integrity, and realization of rapid and efficient coagulating sedimentation and magnetic separation of 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.
