Description

Technical Field

[0001] The utility model relates to the technical field of regenerated particle production, in particular to a structure for removing iron impurities from waste plastics. Background Art

[0002] When recycling plastics, there are many plastic wastes mixed with some steel wires, such as waste tires. As the plastic waste is crushed, the steel wires are also crushed into iron filings, which need to be separated at this time.

[0003] Traditionally, iron chips have been separated by directly directing the scraps into a channel equipped with magnets, where fixed magnets attract the iron chips within the plastic. However, after prolonged operation with this method, a large amount of iron chips adheres to the magnets, necessitating shutdown to clean them. Failure to promptly clean the magnets can compromise the ability to absorb the chips.

[0004] However, if the machine is stopped to clean the iron filings on the magnet, the iron filings removal process will be interrupted, affecting the corresponding production processes upstream and downstream. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a waste plastic iron impurity removal structure, which can realize the convenient cleaning of iron chips on the magnetic plate without stopping the machine, thereby ensuring the efficient and continuous operation of the iron chip removal process.

[0006] The utility model is realized through the following technical solutions:

[0007] The utility model provides a structure for removing iron impurities from waste plastics, comprising an iron scrap adsorption bin, a vertical conveyor belt disposed within the bin, a discharge channel formed between the vertical conveyor belt and a housing on one side of the bin, and a secondary separation chamber formed between the vertical conveyor belt and a housing on the other side of the bin. Multiple iron scrap handling assemblies are elastically mounted on the surface of the vertical conveyor belt. The iron scrap handling assemblies include a rotating plate rotatably connected to the vertical conveyor belt at one end and elastically connected to the vertical conveyor belt at the other end. A magnetic plate is embedded in the outer side of the rotating plate, wherein the magnetic plate in the discharge channel is tilted upward.

[0008] The iron chip adsorption bin is equipped with a motor, the output end of the motor is connected to a rotating shaft vertically inserted into the secondary separation chamber, a rotating brush is provided on the ring side of the rotating shaft, and a vertical stripping baffle is also fixedly installed in the secondary separation chamber. The rotating brush in one direction of the rotating shaft contacts the magnetic plate, and the rotating brush in the other direction of the rotating shaft contacts the stripping baffle.

[0009] As a preferred technical solution of the utility model: the iron chip adsorption bin is provided with a feed port located above the discharge channel, a feed slope is provided at the top of the discharge channel and connected to the feed port. The iron chip adsorption bin is provided with a discharge port located below the discharge channel, and a discharge slope is provided at the bottom of the discharge channel and connected to the discharge port.

[0010] As a preferred technical solution of the present invention, the chip adsorption bin is equipped with a chip discharge port located below the secondary separation chamber. The bottom of the secondary separation chamber is provided with a chip drop slope connected to the chip discharge port. The chip drop slope is also equipped with bottom-side brushes that contact the magnetic plate at the bottom of the vertical conveyor belt.

[0011] As a preferred technical solution of the present invention: the vertical transmission belt is provided with a first fixing member for rotationally cooperating with one end of the rotating plate and a second fixing member for elastically cooperating with the other end of the rotating plate.

[0012] As a preferred technical solution of the present invention: a connecting piece is provided at the other end of the rotating plate, and a tension spring is connected between the second fixing piece and the connecting piece.

[0013] As a preferred technical solution of the present invention, the vertical distribution range of the rotating brushes matches the vertical downward range of the chip processing assembly driven by the vertical conveyor belt. The vertical installation range of the stripping barrier matches the rotating brushes.

[0014] Compared with the existing technology, the beneficial effects of the utility model are:

[0015] The utility model arranges a circulating vertical conveyor belt in the iron chip adsorption bin, elastically arranges an iron chip processing component on the vertical conveyor belt, and provides a magnetic plate that can directly contact the feed material, so as to perform efficient iron removal and adsorption operations. At the same time, a rotating brush is arranged in the secondary separation chamber to clean the magnetic plate that is not in contact with the feed material, and a stripping baffle is used to clean the iron chips attached to the rotating brush (the rotating brush collides with the stripping baffle when rotating, and the attached iron chips are separated out), thereby ensuring the re-cleaning of the rotating brush, thereby achieving relatively convenient cleaning of the iron chips on the magnetic plate without stopping the machine, and ensuring the efficient and continuous operation of the iron chip removal process.
