Embodiment 1

[0039] A sorting device after fine crushing treatment of scrap metal, such as figure 1 As shown, it includes a frame-shaped fixed frame 37 and a magnetic roller 32 fixed on the fixed frame 37 through bearings. The two sides of the cylinder surface of the magnetic roller 32 are provided with a feeding conveyor belt 31 and an output conveyor belt respectively fixed on the fixed frame 37. Material conveyor belt; wherein: the end of the feeding conveyor belt 31 is close to one side of the magnetic drum 32, and there is a blanking gap for non-ferrous materials; the beginning of the discharge conveyor belt is infinitely close to the other side of the magnetic drum 32. , can be close to the drum surface, such as 1 mm apart between the two, to facilitate the interception of the absorbed iron material;

Embodiment 2

[0042]The waste metal finely crushed sorting device of this embodiment has the same basic structure as that of Embodiment 1, and the improvement is that: there are two discharge conveyor belts, which are arranged in parallel up and down, and the upper and lower sides are respectively a large-grain iron material conveyor belt 33 and a small-grain iron material conveyor belt. Conveyor belt 34; the cylinder surface of described large grain iron material conveyer belt 33 and magnetic cylinder 32 reserves a gap, in the present embodiment, the gap size is 15mm; Described small grain iron material conveyer belt 34 is infinitely close to the cylinder surface of magnetic cylinder 32, can Close to the cylinder surface, for example, the distance between the two is less than 1mm.

Embodiment 3

[0046] The waste metal finely crushed sorting device of this embodiment has the same basic structure as that of Embodiment 2, and the improvement is that the conveying speed of the discharge conveyor belt is greater than the feeding speed of the feeding conveyor belt 31, and the advantage is that the iron material after adsorption can be absorbed. After the large-particle iron material conveyor belt 33 and the small-particle iron material conveyor belt 34 are respectively intercepted, they are transferred as soon as possible to reduce the secondary adsorption of the iron material and avoid accumulation at the junction due to the secondary adsorption as much as possible. A non-ferrous material collection box 321 is arranged at the bottom of the non-ferrous material blanking gap, and a large-particle iron material collection box 331 and a small-particle iron material collection box 331 are respectively arranged at the ends of the large-particle iron material conveyor belt 33 and t...

Abstract

The invention discloses a classifying device used after fine crushing of waste metal and a classifying method for the classifying device and belongs to the technical field of classifying after metal crushing. The classifying device comprises a frame-shaped fixing frame and a magnetic roller fixed to the fixing frame through a bearing. A feeding conveying belt and a discharging conveying belt fixedto the fixing frame are arranged on the two sides of the roller face of the magnetic roller. The tail end of the feeding conveying belt is closed to the roller face of one side of the magnetic roller, and a non-iron material discharging clearance is reserved. The initial end of the discharging conveying belt is attached to the roller face of the other side of the magnetic roller infinitely. The width of the feeding conveying belt and the width of the discharging conveying belt are not smaller than the width of the magnetic roller. Due to rotation of the magnetic roller, iron materials and non-iron materials are classified, the iron materials are attracted by the magnetic roller and are then cut by the discharging conveying belt to be transferred, the non-iron materials directly fall through the discharging clearance, operation is simple, and classifying is definite. By means of the classifying device and the classifying method, the problem that in the prior art, time and labor are wasted due to manual classifying after metal is crushed.

Description

technical field [0001] The invention belongs to the technical field of post-crushing classification of metals, and in particular relates to a sorting device and a sorting method for scrap metal after finely crushing treatment. Background technique [0002] With the development of the domestic economy and the improvement of people's living standards, the speed of elimination of items is also accelerating. For example, the speed of replacement of waste household appliances and waste cars is getting faster and faster. At present, the domestic treatment of these waste items generally adopts manual disassembly, which is not only labor-intensive, time-consuming and costly, but also pollutes the environment. [0003] A shredder is a machine used for fine crushing, which is generally used to process unprocessed raw materials or scraps to make them smaller in size. It is a kind of heavy-duty mechanical equipment suitable for recycling waste materials such as films, plastics, rubber ...
