Embodiment 1

[0017] see Figure 1~Figure 3 , This eddy current separator for separating non-ferrous metals in solid waste includes collecting troughs 103, 104, vibrating table 101 and belt conveyor 105, and is characterized in that: the collecting troughs 103, 104 and the vibrating table 101 The vibrating table 101 is connected to the belt conveyor 105. At the end of the belt conveyor 105, there is a concentric driven roller 14 that rotates with the conveyor belt, and a baffle plate that contacts the conveyor belt is provided near the bottom of the roller 14. 12. A collecting trough 104 is arranged below the concentric driven drum, and a magnetic roller 13 is arranged in the concentric driven drum 14; its upstream equipment is a vibrating feeder, which evenly disperses the material on the belt 105 of the eddy current separator When the material passes through the magnetic roller 13, an eddy current is generated inside the conductive non-ferrous metal, and the eddy current will also generat...

Embodiment 2

[0018] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0019] The roller group is composed of a driven roller 14, a driven shaft 10, a web 2, and a driven roller shell 1. The roller bearing adopts a self-aligning ball bearing 5; the driven roller 14 and the driven shaft 10 can rotate relative to each other. , the sliding bearing 6 needs to be installed to meet the requirements; the web 2 and the driven drum shell 1 need to be detachable, so bolts are used. In addition, a magnetic roller 13 needs to be placed inside the driven drum 14, and the magnetic roller 13 is mainly composed of a magnet 7, a sleeve 8 and a magnetic yoke 9; the magnet 7 is fixed on the magnetic yoke 9, and the magnetic poles of the adjacent magnets 7 are opposite in polarity; The outside of the magnet 7 is provided with a non-magnetic sleeve 8, which fixes the magnet 7 and prevents foreign matter from entering and affecting its work. The rota...

Embodiment 3

[0023] like Figure 1~Figure 2 As shown, the eddy current sorting machine for separating non-ferrous metals in solid waste, in the sorting machine, the front end of the conveyor belt 105 is provided with a liftable vibrating table 101, and the front end of the vibrating table is provided with a deflection nozzle array 102, A non-ferrous metal material collecting tank 104 is provided below the deflecting nozzle array 102, and a non-metallic material collecting tank 103 is provided on the front side of the non-ferrous metal material collecting tank 104. The deflection nozzle array 102 and the high-pressure gas supply pipe Connection; the vibrating table 101 is connected to the belt conveyor line 105, and the tail end of the belt conveyor 105 is provided with a concentric driven roller 14 that rotates with the conveyor belt, and a magnetic roller 13 needs to be placed inside the driven roller, such as figure 2 The driven roller shaft structure is provided with a baffle plate 12 ...

Abstract

The invention relates to an eddy current sorter for separating non-ferrous metals in solid waste, wherein a material collecting trough connected to a vibration table that is connected to a belt conveyor, a concentric driven drum rotating along the conveyor belt is arranged at the tail end of the belt conveyor, a magnetic roller is required to be placed inside the driven drum, the wheel disk and the drum body are detachable such that a bolt connection is used instead of welding. Baffles that are in contact with the conveyor belt are disposed in the vicinity of the drum, and the material collecting trough is disposed below the concentric driven drum. A non-ferrous metal collecting trough and a non-metallic collecting trough are also fixedly bolted under the channel, and the baffles are placed between the two collecting troughs. By using a hinge mechanism, both the upper baffle and the lower baffle can rotate around the baffle shaft, and both ends of the baffle shaft are tapped and fixedto the frame with nuts. The adjustment of the angle of the upper baffle can be controlled by a square neck bolt. Non-ferrous metals and non-metals (regardless of the two metals of iron and stainless steel) can be collected in different troughs by adjusting the upper baffle in place.

Description

technical field [0001] The invention belongs to the field of non-ferrous metals, in particular to an eddy current separator for separating non-ferrous metals in solid waste. Background technique [0002] Non-ferrous metals are very important basic materials and strategic materials, which are closely related to the development of national economy, science and technology and people's daily life. my country is the largest consumer of non-ferrous metals. The main non-ferrous metal resources have few reserves, low comprehensive utilization efficiency and serious waste. The growth rate of non-ferrous mineral resource consumption is much faster than the economic growth rate. Since the Ministry of Finance, the Ministry of Science and Technology, and the Ministry of Industry and Information Technology jointly issued the "Recycling Nonferrous Metals Industry Development Promotion Plan", as well as other circular economy development work, on the one hand, the waste nonferrous metal rec...
