Problems solved by technology

However, this device has the following disadvantages: when performing magnetic separation, it cannot ensure that the magnetic adsorbent is fully mixed in the sewage and the magnetic field is unevenly distributed, and when cleaning the flocculated pollutants, it cannot effectively remove the flocculated pollutants and magnetic species. Recycling by chemical treatment leads to poor flocculation effect, increased treatment cost, and waste of resources

Abstract

The invention provides a magnetic separation device facilitating separation of sundries in sewage. The magnetic separation device mainly comprises a separating cavity, a power supply device and a control device, wherein the separating cavity comprises a reaction frame body, a rotating shaft, a fixed plate, iron mandrels, separators, a mixer and a collecting tank; annular slides are formed on the fixed plate; the four iron mandrels are arranged in the centers of the four annular slides respectively; the separators are in sliding connection with the annular slides through movable sleeves; each separator comprises a guide rod, an air blowing device and a fixed rod, and the guide rod is arranged on the corresponding movable sleeve in a penetrating manner; the mixer is located below the separators, and electric telescopic rods are arranged at the left end and the right end of the mixer; the collecting tank is of an inverted trapezoidal structure and located below the mixer, a boss is arranged in the horizontal middle of the collecting tank, a mud scraping device is arranged in the boss in a penetrating manner, and a collecting box is arranged below the collecting tank. The magnetic separation device is reasonable in structure and good in flocculation effect, floccular pollutants and magnetic seeds are effectively treated and recovered, and the treatment cost is reduced.

Description

Technical field [0001] The invention belongs to the technical field of water treatment, and specifically relates to a magnetic separation device that is convenient for separating sewage impurities. Background technique [0002] In processes such as sewage treatment and purification, the effect of magnetic fields on water, other solvents and dissolved oxygen can be used to directly degrade organic matter. The magnetic effect can promote the dissolution of oxygen in water and may generate active oxygen in the water. These active oxygen groups have strong oxidizing properties and can oxidize organic matter in water, thereby reducing the content of organic matter in the water. Moreover, the magnetic field generated by the rotating magnet bar can play a certain stirring effect, and the organic particles can adhere to the magnetic flocculant, so that the contaminants adsorbed on the magnetic powder can be magnetically aggregated and flocculated and accelerate the sedimentation. The m...
