Description

Technical Field

[0001] The utility model relates to the technical field of iron powder separation, in particular to a magnetic separation material structure. Background Technique

[0002] During the electrolytic aluminum process, a mixture of electrolyte and rust will form on the surface of the anode steel claw after it is separated from the electrolytic cell. In order to realize the reuse of the electrolyte, it is necessary to separate the iron powder from the electrolyte. Currently, a magnetic separation device is used. When the mixture passes through the rotating drum, the magnet inside the drum adsorbs the iron powder on the surface of the drum, and the electrolyte is collected. When the drum rotates to the area without a magnet, the iron powder detaches, completing the collection of the iron powder.

[0003] However, the following problems will occur during the separation process: (1) When the feeding chute feeds materials to the surface of the drum, some of the mixture will not rotate along the direction of the drum, but slide down from the other side of the drum, resulting in waste; (2) When the iron powder passes through the area without a magnet, it will not completely fall, but continue to rotate with the drum to the magnet area, resulting in low iron powder collection efficiency; (3) After the mixture falls into the drum, it accumulates together, and the iron powder cannot be completely adsorbed, resulting in the presence of iron powder in the collected electrolyte, affecting the iron powder separation effect. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the existing defects, provide a magnetic separation material structure, which can improve the adsorption efficiency of iron powder in the mixture, prevent some of the mixture from falling without being separated at the same time, avoid waste, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A magnetic separation material structure includes a drum and a magnetic roller with a notch. The drum is arranged outside the magnetic roller. The drum is rotatable, and the magnetic roller is a fixed structure. A feeding chute is arranged above the drum. A retaining belt is arranged at the lower end of the feeding chute. The lower end of the retaining belt contacts the surface of the drum. At least two material retaining strips are evenly distributed on the outer side surface of the drum.

[0006] As a preferred technical scheme of the utility model, the retaining belt deviates from the central axis of the drum by 3 - 5 mm.

[0007] As a preferred technical scheme of the utility model, the retaining belt is made of wear-resistant canvas tape.

[0010] As a preferred technical solution of the present utility model, the material blocking strip protrudes from the surface of the drum by 8-10 mm.

[0011] As a preferred technical solution of the present utility model, the retaining belt is connected to the bottom of the blanking chute by screws.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: (1) By arranging a retaining belt between the blanking chute and the drum, the mixture can only fall along the rotation direction of the drum when flowing out of the blanking chute, and the retaining belt plays a role of blocking on one side; (2) The arrangement of the retaining belt enables a small number of iron powders that continue to rotate with the drum to be scraped off by the retaining belt when passing through the non-magnet area, improving the iron powder collection efficiency; (3) By arranging a plurality of material blocking strips on the outer side surface of the drum, the rolling of the mixture can be slowed down, enabling the mixture to spread out on the surface of the drum, improving the adsorption efficiency of the magnetic roller for iron powder, and further enabling the complete separation of the iron powder from the electrolyte, greatly improving the separation efficiency.

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments (for the convenience of description and understanding, the upper part is described as the upper part hereinafter). All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Figure 3 Please refer to

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: a magnetic separation material structure, including a drum 1 and a magnetic roller 2 with a notch. The drum 1 is arranged outside the magnetic roller 2. The drum 1 is connected to an external driving mechanism, so that the drum 1 rotates counterclockwise. The magnetic roller 2 is a fixed structure. There is a feeding chute 3 above the drum 1. There is a retaining belt 4 at the lower end of the feeding chute 3. The lower end of the retaining belt 4 contacts the surface of the drum 1. The retaining belt 4 deviates from the central axis of the drum 1 by 3 - 5 mm. Under the action of the retaining belt 4, when the mixture falls from the feeding chute 3, it can only roll along the rotation direction of the drum 1, and the other side is blocked by the retaining belt 4. At the same time, part of the iron powder adsorbed on the surface of the drum 1 does not fall when passing through the non-magnetic area, and is scraped off by the retaining belt 4 when passing through the retaining belt 4, which is convenient for completely collecting the iron powder;

[0019] There are three material retaining strips 5 evenly distributed on the outer side surface of the drum 1. The material retaining strips 5 protrude from the surface of the drum 1 by 8 - 10 mm, slowing down the rolling speed of the mixture, reducing the thickness of the mixture on the surface of the drum 1, controlling the thickness of the adsorbed material, and improving the adsorption effect of the magnetic roller 2 on the iron powder.

[0020] Furthermore, in order to ensure that the retaining belt 4 has a certain hardness, the retaining belt 4 is made of wear-resistant canvas tape.

[0021] Furthermore, in order to slow down the friction between the material retaining strip 5 and the retaining belt 4 and extend the service life of the retaining belt 4, a plurality of slits 6 are evenly divided on the retaining belt 4. By cutting the plurality of slits 6, the retaining belt 4 has a certain flexibility, slowing down the wear with the material retaining strip 5.

[0022] Furthermore, in order to facilitate the replacement of the retaining belt 4 and the feeding chute 3, the retaining belt 4 is connected to the bottom of the feeding chute 3 through screws 7.

[0023] During use: The mixture of electrolyte and iron powder falls on the surface of the drum 1 through the feeding chute 3. At this time, the drum 1 rotates counterclockwise under the action of the external driving mechanism. The retaining belt 4 blocks the mixture from falling from the other side of the drum 1. The speed of the mixture slows down when passing through the material retaining strip 5. The magnet on the magnetic roller 2 adsorbs the iron powder, and the electrolyte falls into the collection hopper. When the iron powder adsorbed on the drum 1 passes through the non-magnetic area, it falls into the iron powder collection box due to the lack of magnetic force, completing the separation and collection of the iron powder and the electrolyte. A small amount of iron powder still adsorbed on the surface of the drum 1 is scraped off when passing through the retaining belt 4, and the iron powder falls and is collected.

[0024] The present utility model can improve the adsorption ability and efficiency of the iron powder in the mixture, realize the complete separation of the electrolyte and the iron powder, greatly improve the separation and collection quality of the electrolyte and the iron powder respectively, and realize the recycling and reuse of the electrolyte.

[0025] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
