Longitudinal roller and transverse disk type rare earth magnetic disk separation device for arc shell bottom plate

Abstract

The invention discloses a longitudinal roller and transverse disk type rare earth magnetic disk separation device for an arc shell bottom plate. The device comprises longitudinal magnetic rollers andtransverse magnetic disk groups which are perpendicularly mounted in an adsorption tank, wherein the longitudinal magnetic rollers are mounted on a fixing rack, the transverse magnetic disk groups aremounted on one side wall of the adsorption tank, and the longitudinal magnetic rollers adopt conical structures and are parallel with the water flow direction; each transverse magnetic disk group consists of a plurality of magnetic disks; each magnetic disk comprises a magnetic disk body, a plurality of mounting through holes are formed in the magnetic disk body, intermediates are placed in the middle of the mounting through holes, two rare earth NdFeB magnets are placed on two sides of each intermediate, centers of the magnetic disk bodies bulge and have clamping grooves, and inner edges ofstainless steel guard boards on two sides of the magnetic disk body are fixedly mounted in the clamping grooves. The rare earth magnetic disk separation device has the technical benefits as follows: the lower part of the adsorption tank is designed into an arc shell, so that although suspended solids with larger specific gravity settle at the bottom of water after being coagulated, the effective time of the suspended solids is greatly prolonged when the suspended solids pass through magnetic disks.

Description

technical field [0001] The patent of the present invention relates to the technical field of rare earth disk separation of arc shell bottom plate, specifically a rare earth disk separation device of vertical roller and horizontal plate type arc bottom shell. Background technique [0002] The rare earth disk separation technology was first applied to the treatment of steel rolling wastewater. The core technology is the rare earth disk. When the fluid flows through the flow channel between the rare earth disk groups, the magnetic suspension flocs contained in the fluid are subjected to strong magnetic force and adsorbed on the On the surface of the disk, as the disk rotates, it is gradually separated from the water body. [0003] Since around 2008, on the basis of using the treatment of steel rolling wastewater, the application scope of separation technology has been expanded to coal mine wastewater and other aspects. Due to the complex composition of various suspended solids...

AI Technical Summary

Problems solved by technology

Therefore, coagulation with a small specific gravity is suspended in water and is directly absorbed when passing through the disk, while coagulation with a large specific gravity is easy to settle in water, and there is a problem that it is easy to settle to the bottom of the disk when passing through the disk and is not easy to be completely absorbed.
