[0003] As a result, there is a mica beneficiation equipment with patent number CN216063744U, but while solving the above problems, the equipment has the following technical defects, such as: due to the influence of distance and the fact that metal impurities are buried in other products, it is difficult to adsorb or clean the metal impurities flowing on the conveyor belt below it only by the attractive magnetic force generated by the magnetic separation part. Summary of the invention

[0004] The purpose of the present invention is to provide a magnetic suction device for mineral processing.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] A magnetic suction device for mineral processing, comprising a box 1:

[0020] Magnetic suction mechanisms 2 are arranged on both sides of the box body 1, wherein two groups of magnetic suction mechanisms 2 are staggered up and down, and a collecting hopper 3 is arranged on the inner wall of the box body 1 directly below each group of magnetic suction mechanisms 2, and a conveyor belt 4 located above the corresponding collecting hopper 3 is also arranged in the box body 1 below the magnetic suction mechanism 2, wherein a feeding mechanism 5 arranged on the same side as the uppermost magnetic suction mechanism 2 is arranged on the top of the box body 1;

[0021] The magnetic attraction mechanism 2 includes a driving roller 21 driven by a motor 1, wherein an electromagnet layer 22 is wrapped on the outer wall of the driving roller 21, and a plurality of groups of electromagnet plates 23 are radially arranged on the outer wall of the driving roller 21;

[0022] The feeding mechanism 5 includes an inclined barrel 51, the top of which is provided with a feeding port, wherein the bottom of the barrel 51 is provided with a connecting pipe 52 connected to the box body 1, and the connecting pipe 52 is located directly above the two adjacent groups of electromagnet plates 23 in the upper magnetic attraction mechanism 2, and a rotating shaft 54 ​​driven by a motor II53 is also provided in the barrel 51, wherein a breaking rod 55 is provided on the rotating shaft 54.

[0023] The connecting tube 52 is a square tube structure, and a sliding opening 6 is provided on one side wall of the connecting tube 52, wherein a baffle 7 is provided in the sliding opening 6 to seal the inner opening of the connecting tube 52, and the baffle 7 is driven by an electric push rod 8, and a card groove 9 for accommodating the edge of the baffle 7 is provided around the inner wall of the connecting tube 52.

[0024] like Figure 1 As shown, one end of the upper conveyor belt 4 is located just above the space between two adjacent sets of electromagnet plates 23 in the lower magnetic attraction mechanism 2 .

[0025] The side wall of the box body 1 is provided with a discharge port 10 connected with the corresponding collecting hopper 3, and the side wall of the box body 1 is also provided with an installation opening for the conveyor belt 4 below to pass through.

[0026] A sieve plate 11 is arranged above the conveyor belt 4 and is arranged on the same side as the corresponding magnetic attraction mechanism 2 , wherein the sieve plate 11 is arranged obliquely on one side of the bottom of the corresponding magnetic attraction mechanism 2 .

[0027] Method of use: introduce the material into the barrel 51 and let it flow downward along its inclined wall. At this time, the motor II53 drives the rotating shaft 54 ​​to drive the crushing rod 55 to rotate, which can effectively break up the material and disperse it. Then, the material enters the two adjacent groups of electromagnet plates 23 in the upper magnetic attraction mechanism 2 through the opened connecting pipe 52. At this time, the motor I drives the driving roller 21 and the electromagnet plate 23 to rotate counterclockwise. When the material falls between the two groups of working electromagnet plates 23, the electromagnet layer 22 and the electromagnet plate 23 that are powered on can adsorb the metal impurities flowing into the material, thereby removing the metal impurities in the material. When the magnetic attraction mechanism 2 rotates, it will drive the material inside it to roll and slide on the end surface of the electromagnet plate 23 and the electromagnet layer 22, so that the metal impurities are fully in contact with the end surface of the electromagnet plate 23 and the electromagnet layer 22, thereby achieving the purpose of removing metal impurities in the material by magnetic attraction.

[0028] Then the material with metal impurities initially removed falls on the upper screen plate and flows along its inclined surface to the top of the upper conveyor belt. At this time, the screen plate plays the role of screening the material falling from the magnetic suction mechanism, so that it is evenly spread on the conveyor belt. Then the upper conveyor belt transports the material to the left and falls on the top of the lower magnetic suction mechanism, and then the metal impurities that may continue to be mixed in the material are further magnetically screened in the same way as above. Finally, the material falls on the lower conveyor belt and flows out;

[0029] In the above process, the electric push rod 8 drives the baffle 7 to move in the sliding opening 6 and the connecting pipe 52, thereby controlling the flow of the material in the barrel 51 entering the box body 1 to prevent the feed amount from being too large or too small to affect the processing work. At the same time, the material is evenly introduced into the magnetic attraction mechanism 2 in the rotating process. When the material is introduced between any two adjacent sets of electromagnetic iron plates 23, it can play a magnetic attraction and remove metal impurities in the material.

[0030] When the metal impurities adsorbed on the electromagnet layer 22 and the electromagnet plate 23 need to be cleaned after processing for a period of time, the conveyor belt 4 is reversed, and the electromagnet layer 22 and the electromagnet plate 23 are powered off while continuing to rotate. Then, the metal impurities adsorbed on the electromagnet layer 22 and the electromagnet plate 23 will fall onto the corresponding conveyor belt 4, and the conveyor belt 4 will transport the impurities to the corresponding collecting hopper 3 below it for discharge, so as to facilitate the cleaning of the metal impurities obtained by magnetic absorption.

[0031] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
