A magnetic coagulation high gradient magnetic separator

Abstract

The present application relates to the field of magnetic separators, in particular to a magnetic coagulation high-gradient magnetic separator, which includes a casing in which a magnetic cylinder is rotatably connected, and the inner wall of the magnetic cylinder is connected with a magnetic body. There are sludge inlet and sludge outlet. The sludge inlet and sludge outlet are located on both sides of the magnetic cylinder. The casing is connected with a scraper. The scraper and the sludge outlet are located on the same side of the magnetic cylinder. The outer wall abuts, and the bottom of the casing is rotatably connected with a flap. The flap includes the first turning board and the second turning board that are perpendicular to each other and are fixedly connected. The connection position of the first turning board and the second turning board is connected to the inner wall of the casing by rotation , the rotation axis of the flap is perpendicular to the axis of the magnetic cylinder, a flushing device is arranged in the casing, and the flushing device is located on the side of the magnetic cylinder close to the sludge inlet. The application has the effect of improving the recovery rate of magnetic powder.

Description

technical field [0001] The present application relates to the field of magnetic separators, in particular to a magnetic coagulation high-gradient magnetic separator. Background technique [0002] Magnetic coagulation technology is a new type of water treatment technology that separates substances with different magnetic properties by means of an external magnetic field. Settle the magnetic mixture, efficiently remove suspended solids, total phosphorus and other pollutants from the sewage, and the added magnetic powder is recycled through the magnetic powder recovery system, which greatly reduces the operating cost of the project. Compared with traditional water treatment technology, magnetic coagulation has the advantages of low operating cost, good effluent quality, good phosphorus removal effect, strong impact load resistance, and high efficiency. [0003] With the rise of the magnetic coagulation clarification tank process, the magnetic separation technology has also bee...

Problems solved by technology

However, due to the inability of the sludge to fully contact with the magnetic body and the low magnetic field strength of the magnetic body, the recovery rate of the magnetic powder in the sludge is very low, and the recovery of the magnetic powder is still very difficult.

The low recovery rate of magnetic powder will lead to high magnetic powder content in sludge. Due to the high hardness of magnetic powder, magnetic powder will cause irreversible wear to sludge treatment equipment, and the wear will be fast and the loss will be huge.
