[0002] Aluminum, as one of the conductive materials, can be produced into electrical wires. When recycling discarded electrical wires, the plastic skin on the outside of the aluminum wire needs to be removed, but there is still some aluminum wire left inside the plastic skin. In order to avoid waste, the aluminum wire and the plastic skin need to be separated by electrostatic separation equipment.

[0003] In the prior art, Chinese patent publication number CN214440021U discloses a five-roll aluminum-plastic electrostatic separator, which relates to the technical field of sorting devices, including a shell and a hopper arranged on the top of the shell, and also includes a primary separation mechanism arranged in the shell and below the hopper, two secondary separation mechanisms are arranged below the primary separation mechanism, and a tertiary separation mechanism is arranged below each secondary separation mechanism, wherein the primary separation mechanism includes a first grounded separation roller and a first mesh electrostatic frame arranged on the shell, and an electrostatic separation channel is formed between the first grounded separation roller and the first mesh electrostatic frame. The present application forms a five-roll aluminum-plastic electrostatic separator with a triple sorting function by setting a primary separation mechanism, a secondary separation mechanism and a tertiary separation mechanism, which can perform double sorting on the coarse particle size material and the fine particle size material separated by the primary separation mechanism, respectively, with high sorting purity, and reasonable structural design and layout, thereby improving sorting efficiency.

[0004] However, the existing electrostatic separation equipment has poor separation effect when separating plastic skin and aluminum wire, and the waste aluminum wire is heavy and difficult to load. After the separation, the aluminum wire is also difficult to discharge. Therefore, the above problems need to be improved. Utility Model Content

[0005] The utility model aims to provide an electrostatic separation device, which has a good effect of separating plastic skin and aluminum wire.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an electrostatic separation device, including a separation body, a material pipe is inserted into the top of the separation body, a material bin is fixedly connected to the top of the material pipe, a material discharge channel is fixedly connected to the inner side of the material bin, a first motor is fixedly installed on the outer side of the material pipe, a driving shaft is fixedly connected to the output end of the first motor, a breaking blade is fixedly connected to the outer side of the driving shaft, a second motor is fixedly installed on the outer wall of the separation body, a discharge roller is fixedly connected to the output end of the second motor, a conductive plate is fixedly connected to the outside of the discharge roller, a conductive wire is arranged inside the conductive plate, a cylinder is fixedly installed on both sides of the inner wall of the separation body, a push rod is arranged at the output end of the cylinder, a scraper is fixedly connected to one end of the push rod, and a first discharge channel and a second discharge channel are respectively arranged inside the separation body.

The plastic skin enters the interior of the separation body through the material pipe, and the second motor is started, so that the second motor drives the discharge roller, the conductive plate and the conductive wire to rotate, and the conductive wire is started to release static electricity. Since the plastic skin and the aluminum wire inside the plastic skin have different properties, the plastic skin passes through the discharge roller with a point. The electric roller will generate an adsorption force, and the plastic skin will be adsorbed on the outside of the discharge roller. When the aluminum wire hits the discharge roller, it will be separated from the discharge roller, thereby separating the plastic skin from the aluminum wire inside the plastic skin. At this time, the aluminum wire will fall into the inner bottom wall of the separation body, and the cylinder will be started, so that the cylinder drives the scraper to move through the push rod, thereby pushing the aluminum wire into the inside of the second discharging channel, and the aluminum wire is discharged from the outside of the separation body through the second discharging channel. The conductive wire is turned off, and the conductive wire stops preventing electricity. The plastic skin on the outside of the discharge roller will be separated from the discharge roller, and the plastic skin is discharged from the inside of the separation body through the first discharging channel, so that the device can not only separate the plastic skin and the aluminum wire, but also has a good separation effect.

[0016] The utility model is further configured as follows: both sides of the conveying frame are fixedly connected with mounting plates, and the mounting plates are fixed on the top of the silo.

[0021] By adopting the above technical solution, when discharging the plastic skin and aluminum wire inside the discharge box, the fourth motor is started, so that the fourth motor drives the cross column and the spiral blades to rotate. The spiral blades are spiral-shaped and the spiral blades are coiled on the outer wall of the cross column. When the plastic skin and aluminum wire come into contact with the spiral blades, the plastic skin and aluminum wire will be transported, so that the device can continuously feed and discharge the plastic skin and aluminum wire.

The first motor drives the scattering blades to rotate through the driving shaft. When the plastic skin flows into the interior of the material pipe, it will contact the scattering blades. The rotation of the scattering blades can scatter the plastic skin, thereby preventing the plastic skin from agglomerating when being separated from the aluminum wire inside the plastic skin. The second motor drives the discharge roller, the conductive plate and the conductive wire to rotate, and starts the conductive wire so that the conductive wire releases static electricity. Due to the plastic skin and the aluminum wire inside the plastic skin, the plastic skin is spun off.

When the aluminum wire touches the discharge roller, it will separate from the discharge roller, so that the plastic skin and the aluminum wire inside the plastic skin can be separated.
