Magnetic plate liquid purifying device

Abstract

The invention which belongs to the sewage processing field especially relates to a magnetic separation purifying device. The magnetic plate liquid purifying device comprises a separator, residue scraping mechanisms and a residue discharge mechanism, wherein the separator is obtained through vertically fixing two or more than two magnetic plates which are arranged in a parallel mode on the separator supporting frame at the inner wall of a tank; each of the magnetic plates is composed of a magnetic adsorption zone and a non-magnetic residue discharge zone; the non-magnetic residue discharge zones of all the magnetic plates are linearly arranged along the radial direction of the magnetic plates; and a wastewater channel is formed between each two magnetic plates. The device allows the magnet residue adsorption capability to be greatly improved, and has a strong impact load resistance.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a magnetic separation and purification device. Background technique [0002] Magnetic separation is a technology that achieves material separation through the magnetic field attraction provided by a magnet. It belongs to the physical separation method and was developed in the United States in the early 1970s. It can quickly separate magnetic impurities in a mixture. Magnetic separation uses the magnetism of impurity particles in wastewater to separate. For non-magnetic or weakly magnetic particles in water, magnetic seeding technology can make them magnetic. With the help of the external magnetic field, the magnetic suspended solids in the wastewater are separated, so as to achieve the purpose of purifying the water. Compared with conventional methods such as sedimentation and filtration, the magnetic separation method has a series of advantages such as large processing capacity,...

Problems solved by technology

[0004] In the existing disk-type magnetic separator, there are always the following problems: 1. In the magnetic separation equipment, it is important that the wastewater supplied to the magnetic separator should contact the disk evenly, so as to effectively remove the magnetic flocs in the wastewater

However, in the existing magnetic separation equipment, the magnetic disk cannot be in equal contact with the waste water, and the magnetic disk is half-submerged in the waste water, and the adsorption performance of the magnetic disk cannot be fully utilized; 2. When the magnetic disk rotates from the waste water and enters the air, Magnetic flocs are fixed on the disk surface and are difficult to remove
