Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.

Fig. 1 is a schematic structural diagram of an electrostatic separation apparatus according to a preferred embodiment of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

Referring to fig. 1, the embodiment of the present invention discloses an electrostatic separation device, which comprises a housing 1, an electrostatic separation mechanism disposed in the housing 1, and a feeding mechanism 2 disposed above the housing 1, wherein the feeding mechanism 2 comprises a feeding hopper 21, vibration feeder 22 be connected with feeder hopper 21 and the feedstock channel 23 with vibration feeder 22 intercommunication, the export of feedstock channel 23 communicates in with casing 1, feedstock channel 23 has the inclined plane that guides the material gliding and form the material curtain, electrostatic separation mechanism is including equal vertical setting's pivot 3 (iron pivot) and electrode otter board 4, pivot 3 is rotated by motor drive, pivot 3 and electrode otter board 4 set up relatively, the bottom that casing 1 is located between pivot 3 and the electrode otter board 4 is provided with the collection fill 5 that is used for the cell-phone mixture, the both sides of casing 1 are provided with the discharge gate 7 that is used for collecting the discharge gate 6 of metal and is used for collecting plastics respectively.

When the electrostatic separation device provided by the embodiment of the utility model works, after the high-voltage electrode is electrified, the roller rotates to form an electrostatic field, and materials (mixed powder of aluminum powder and plastics) enter the feeding channel 23 from the vibration feeder 22 and fall into the shell 1 along the inclined plane, so that a material curtain is formed; the aluminum powder repels the same polarity between the charged aluminum powder and the rotating shaft 3, so that the aluminum powder is repelled and ejected out, passes through meshes on the electrode mesh plate 4 and falls downwards under the action of gravity, and then flows out of the discharge hole; the plastic powder is adsorbed on the rotating shaft 3 under the action of like-polarity attraction, when the rotating shaft 3 rotates to one side far away from the electrode mesh plate 4, the plastic powder loses power and drops from the rotating shaft 3, and drops downwards under the action of gravity, so that the plastic powder flows out from another discharge hole.

As one of the preferred proposals of the utility model, a plurality of circular holes are evenly distributed on the electrode screen plate 4. The circular hole can reduce the resistance that metal powder passed through, and the circular hole size is fit for and density is great to guarantee that metal powder can pass through electrode mesh plate 4 to the greatest extent.

As one preferable embodiment of the present invention, the electrode mesh plate 4 has an arc-shaped structure and forms a half-surrounding state with respect to the rotating shaft 3. The electrode mesh plate 4 forms a semi-surrounding state for the rotating shaft 3, so that the separation effect of an electrostatic field formed between the rotating shaft 3 and the high-voltage electrode can be ensured, and metal powder can collide with the electrode mesh plate 4.

In actual work, like poles repel each other and are repelled and ejected out between the aluminum powder and the rotating shaft 3, the plastic powder is adsorbed on the rotating shaft 3 under the action of like poles attract each other, but not all the aluminum powder can pass through the electrode mesh plate 4, and not all the plastic powder can be adsorbed on the rotating shaft 3, so that some unseparated materials are inevitably generated in the continuous separation process of the materials, and the unseparated materials still have value and can be collected and separated, and therefore the collecting hopper 5 is designed for collecting the unseparated materials.

As one of the preferred schemes of the utility model, the bottom of collecting and fighting 5 is equipped with a bottom cover plate 8, and the one end of bottom cover plate 8 is articulated with collecting and fighting 5, and the other end of bottom cover plate 8 is articulated with cylinder 9's telescopic link, and cylinder 9's afterbody is articulated with casing 1's outer wall. A pressure sensor is arranged on the collecting hopper 5, and a collecting box 10 for collecting mixture is arranged below the bottom cover plate 8.

When the mixture in the collecting hopper 5 reaches certain weight, the pressure sensor senses the signal, so that the cylinder 9 drives the bottom cover plate 8 to rotate to open the bottom cover plate 8, and the mixture can fall into the collecting box. The collection of the mixture can be automatically completed without considering the amount of the mixture in the collection hopper 5.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
