DETAILED DESCRIPTION OF THE EMBODIMENTS

[0011] The following further elaborates on the utility model in detail in conjunction with the drawings and specific embodiments.

[0012] A coarse filter for the production of hexagonal boron nitride includes a filter body 1, a distribution box 2, a U-shaped electromagnetic structure 3, a grading discharge port 4, a drive motor set 5, and a feeding roller 6. There are two groups of the U-shaped electromagnetic structures 3, and the two groups of U-shaped electromagnetic structures 3 are arranged side by side up and down on the side surface of the filter body 1. There are two groups of the grading discharge ports 4, and the two groups of grading discharge ports 4 are respectively arranged on the two side surfaces of the filter body 1. The two groups of grading discharge ports 4 are correspondingly arranged at the bottom sides of the two groups of U-shaped electromagnetic structures 3. A top feeding port 7 is opened on the top side of the filter body 1, a direct discharge port 8 is opened on the lower side of the filter body 1. The drive motor set 5 is fixed on the top side surface of the filter body 1. The feeding roller 6 is arranged at the inner bottom side of the top feeding port 7, and the side end of the feeding roller 6 is connected to the drive motor set 5. The distribution box 2 is arranged on one side of the filter body 1. The U-shaped electromagnetic structure 3 and the drive motor set 5 are both electrically connected to the distribution box 2. The magnetic pole directions of the two groups of U-shaped electromagnetic structures 3 are opposite.

[0013] Inside the filter body 1, a material-scooping inclined plate 9 is provided. The material-scooping inclined plate 9 is respectively arranged inside the two grading discharge ports 4. At the bottom side of the top feeding port 7, a roller outer shell 10 is provided. At the bottom side of the roller outer shell 10, a discharge hole 11 is provided. The feeding roller 6 is arranged inside the roller outer shell 10, and the feeding roller 6 can rotate inside the roller outer shell 10. A number of groups of long-strip embedded material grooves 12 are formed on the feeding roller 6. The number of groups of long-strip embedded material grooves 12 are arranged on the feeding roller 6 at equal circumferential angles. The discharge hole 11 is arranged at the center of the inner top side of the filter body 1.

[0014] Working principle of the present utility model: This structure works by utilizing the diamagnetic property of hexagonal boron nitride. The raw materials are fed through the top feeding port 7. During the rotation of the feeding roller 6 for the raw materials in the feeding port, the raw materials enter the long-strip embedded material grooves 12. Moreover, larger raw material particles can be further crushed so that they can enter the long-strip embedded material grooves 12. When the raw materials move from the long-strip embedded material grooves 12 to the bottommost end and fall into the filter body 1 through the discharge hole 11. When the U-shaped electromagnetic structure 3 is powered on to form a magnetic field, the magnetic field will drive the raw material particles therein to move to one side. Different magnetic pole directions can drive the raw material particles to move in different directions, and then fall onto the two different material-scooping inclined plates 9 on both sides and are discharged through the grading discharge ports 4. While larger particles or even particle materials with small diamagnetism are less affected by the magnetic field reaction and are finally discharged through the direct discharge port 8.

[0015] The above is the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the teachings of the present utility model, without departing from the principle and spirit of the present utility model, the changes, modifications, substitutions and variations made to the implementation manners still fall within the protection scope of the present utility model.
