Problems solved by technology

However, the current utilization rate and resource utilization are less than 5%, and there is still a big gap between 75% and 90% of construction waste utilization in developed countries. If construction waste management is not strengthened, cities will be "sieged" or even "buried" by construction waste in the future. "
The application number is 201420800958.4, "a suspended magnetic separator": using a belt conveyor and a magnetic system support to achieve magnetic separation, this structure will cause the magnetic system support to be unable to pick up the magnetic material due to the material being transported on the belt conveyor is too thick, Magnetic performance will be affected by how much material is transported
"A flat-plate magnetic separator" with application number 201420341963.3: a leveling device is used to make the material more evenly distributed, so as to achieve better magnetic separation, but the leveling effect of the leveling device directly affects the magnetic separation effect. The material is too viscous, it is difficult to separate the magnetic material from other materials, so the magnetic selection effect is not obvious

Abstract

The invention relates to a brushless magnetic separation device and method. The device comprises a rack, a feeding hopper, a magnetic separation device, a driving motor and a material separation bin.The magnetic separation device is arranged above the material separation bin and comprises an iron separation device and an iron discharging device, the feeding hopper is located at a feeding side ofthe iron separation device, and the iron discharging device is located at an discharging side of the iron separation device. The iron separation device and the iron discharging device are driven by adriving motor to operate and rotate oppositely. A material enters the material separation bin from the feeding hopper, wherein non-ferrous materials are directly discharged from a discharging openingof the material separation bin, and ferrous materials are adsorbed by the iron separation device, conveyed to the iron discharging device and conveyed to an iron discharging opening of the material separation bin through the iron discharging device for discharging. The magnetic discharge effect is good, and incomplete magnetic discharge caused by insufficient sweeping force is avoided. The magnetic separation part is of a double-roller structure, and has clear magnetic selection and magnetic discharge functions and materials are discharged from different channels. A single motor is used for driving in the magnetic separation process, and the energy-saving effect is good. A magnetic control device is adopted, and magnetic materials can be automatically sorted.

Description

technical field [0001] The invention relates to a magnetic separation device in the technical field of construction waste recycling engineering, in particular to a brushless magnetic separation device and a method. Background technique [0002] According to the "Regulations on the Management of Urban Construction Waste", construction waste refers to the construction units, construction units newly built, rebuilt, expanded and demolished various buildings, structures, pipe networks, etc. other waste. With the increase of my country's population and the rapid development of industrialization and urbanization, according to statistics, my country's annual production of construction waste is 3.5×10 9 t, and this data is still growing, and will reach 7.0×10 in the next few years 9 t. However, the current utilization rate and resource utilization are less than 5%, and there is still a big gap between 75% and 90% of construction waste utilization in developed countries. If cons...
