Self-cleaning type magnetic particle separating device

Abstract

The invention relates to a self-cleaning type magnetic particle separating device. The self-cleaning type magnetic particle separating device comprises a shell, an air inlet, magnetic bodies, a dust extraction plate, a motor, a rotating shaft, a dust raise preventing dust collecting box and an air outlet, the air inlet is formed in one end of the shell, the air outlet is formed in the other end of the shell, the dust raise preventing dust collecting box is arranged at the bottom of the shell, all magnetic bodies are transversely arranged in an air runner in an arrayed manner, and the dust extraction plate is arranged on multiple magnetic poles in a sliding and penetrating manner. According to the self-cleaning type magnetic particle separating device, in the dust extraction manner, air containing magnetic particles enters the self-cleaning type magnetic particle separating device through the air inlet to be attracted to the magnetic bodies, and clean air flows out from the air outlet; under the self-cleaning mode, the motor drives the dust extraction plate to move along the magnetic bodies, the particles are separated from the magnetic bodies, the separated particles sink into the dust raise preventing dust collecting box under the action of gravity, a surface magnetic plate and a middle magnetic plate are arranged inside the dust raise preventing dust collecting box, and therefore the sinking magnetic particles can be effectively attracted, and reentrainment of dust is avoided. The self-cleaning type magnetic particle separating device has the beneficial effects of being long in cleaning period, low in maintaining cost, free of reentrainment of dust and the like.

Description

technical field [0001] The invention relates to the technical field of particle separation, in particular to a self-cleaning magnetic particle separation device for removing magnetic particles. Background technique [0002] In industrial and civil fields, the concentration of particulate matter suspended in the air exceeding a certain level will affect process safety and personnel health, so it is very important to control the concentration of particulate matter in the air. An effective means of controlling the concentration of particulate matter in the air is the use of filtration devices. The filter device has the advantage of high efficiency in removing particulate matter, but it needs to be cleaned and replaced frequently in places with a lot of particulate matter, resulting in high operation and maintenance costs for the equipment. [0003] For some occasions where there are many magnetic particles in the air, the filter device is difficult to be widely used due to hig...

AI Technical Summary

Problems solved by technology

Although the current magnetic air purification device can effectively remove magnetic particles in the air, there are still the following problems: first, there is a lack of effective means of cleaning and collecting particles; second, there is a certain secondary dust phenomenon, and the collected particles are easy to enter the air again , becoming a new source of dust
