Description

A brushless magnetic separator

technical field

The utility model relates to a magnetic separation device in the technical field of construction waste recycling engineering, in particular to a brushless magnetic separation device.

Background technique

According to the "Regulations on the Management of Urban Construction Waste", construction waste refers to the spoils, waste materials and waste generated during the construction, reconstruction, expansion and demolition of various buildings, structures, pipe networks, etc. other waste. With the increase of China's population and the rapid development of industrialization and urbanization, according to statistics, the annual production of construction waste in China is 3.5 × 10 ⁹ t, and this data is still growing, and will reach 7.0 × 10 ⁹ t in the next few years. However, the current utilization rate and resource utilization are less than 5%, which is still far behind the 75% to 90% utilization rate of construction waste in developed countries. If construction waste management is not strengthened, the city will be "sieged" or even "buried" by construction waste in the future. ". Therefore, the resource utilization of construction waste is the most important way to control construction waste in the future. At present, the research status reflects that in the process of recycling construction waste, the common method for removing iron impurities is mainly magnetic separation. The existing commonly used magnetic separation method is to install electromagnets directly above the belt conveyor to directly attract ferrous materials, but this method cannot completely clean the ferrous materials because the transported materials are too thick. For this reason, a large number of magnetic separation devices are produced. , for the magnetic separation device, the shortcomings of the existing magnetic separation methods are explained as follows:

The application number is 201820861554.4, the "new high-efficiency magnetic separator": the magnetic separator is an iron discharge device based on a sweeping brush, and the modified device will not completely clean the iron ore due to insufficient sweeping force. Application No. 201610747777.3 "A kind of iron removal and beneficiation device for feldspar ore": the device relies on gravity to make the material fall, and the selection of magnetic materials is realized by a multi-stage magnetic separation mechanism. Magnetic separation, so the energy consumption is large. Application No. 20162001892.0 "A Permanent Magnet High Gradient Magnetic Separator": Gradient separation is realized by relying on permanent magnets. During the rotation process, the bottom is coarse magnetic ore, and the top is refined magnetic ore. It takes one rotation to complete a cycle, and the efficiency is low. . The application number is 201420800958.4, "A suspended magnetic separator": the magnetic separation is realized by using a belt conveyor and a magnetic system bracket. This structure will cause the magnetic system bracket to be unable to absorb the magnetic material due to the thick material transported on the belt conveyor. Magnetic separation performance will be affected by how much material is transported. Application No. 201420341963.3 "a flat-plate magnetic separator": a screeding device is used to make the material more evenly distributed, so as to better realize the magnetic separation, but the screeding effect of the screeding device directly affects the magnetic separation effect. The material is too viscous, and it is difficult to separate the magnetic material from the rest of the material, so the magnetic separation effect is not obvious.
