Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a wheat magnetic separator. Background Art

[0002] During the wheat processing process, such as drying and shelling, impurities such as iron nails and iron filings are easily mixed in. If they are not cleaned, they will cause damage to the equipment during subsequent processing. Therefore, in the actual processing process, it is necessary to use a magnetic separator in time to remove the iron impurities in the wheat.

[0003] In the prior art, a Chinese patent with authorization announcement number CN218962927U discloses a wheat magnetic separator that is easy to clean up debris. The rotating permanent magnetic roller and scraper cooperate to scrape off impurities adsorbed on the permanent magnetic roller, thereby quickly cleaning the permanent magnetic roller. There is no need for manual regular cleaning, which is more convenient and saves trouble. The spiral blades on the rotating rod are driven by the second driving motor to rotate. The rotation of the spiral blades can evenly distribute the wheat, prevent wheat accumulation, and ensure full contact between the wheat and the permanent magnetic roller, thereby improving the effect of wheat cleaning.

[0004] The above-mentioned existing technical solution has the following defects: although it has the advantage of automatically cleaning the permanent magnet roller, it uses the falling method to remove iron impurities in the wheat, and the wheat falls at a fast speed and a large amount, and cannot fully contact with the permanent magnet roller. Therefore, the impurities in the wheat cannot be completely adsorbed by the permanent magnet roller, resulting in poor magnetic separation and impurity removal effect.

[0005] A wheat magnetic separator is proposed for this purpose. Utility Model Content

[0025] like Figures 1 to 3As shown, a wheat magnetic separator includes a base 1, the top surface of the base 1 is fixedly installed with supporting legs 2, a lifting partition 4 and a transverse movement mechanism 7, the top surface of the supporting legs 2 is fixedly installed with a magnetic separation tank 3, the side of the magnetic separation tank 3 is provided with an opening, and a loading box 5 is slidably placed on the top surface of the base 1, the loading box 5 and the opening are respectively arranged on the left and right sides of the lifting partition 4, the front and rear sides of the inner wall of the magnetic separation tank 3 are respectively slidably installed with mounting blocks 8 and component boxes 10, and the surface of the component box 10 close to the mounting block 8 is fixedly installed with a structural box 9, the transverse movement mechanism 7 is used to drive the mounting block 8, the structural box 9 and the component box 10 to move synchronously left and right, a stirring and adsorption component 11 is rotatably installed between the mounting block 8 and the structural box 9, and a rotating drive component 12 for driving the stirring and adsorption component 11 to rotate is provided in the structural box 9, an electromagnetic mechanism 13 is fixedly installed between the mounting block 8, the structural box 9 and the component box 10, and the stirring and adsorption component 11 is sleeved on the outside of the electromagnetic mechanism 13.

[0026] More specifically, by supplying power to the electromagnetic mechanism 13 to generate magnetic force, the iron impurities in the wheat are attracted to adhere to the surface of the stirring and adsorption component 11 set on the outside of the electromagnetic mechanism 13, and the stirring and adsorption component 11 is driven to rotate by the rotating drive component 12. At the same time, the transverse mechanism 7 drives the mounting block 8, the structural box 9 and the stirring and adsorption component 11 to move left and right synchronously, so that the stirring and adsorption component 11 fully stirs the wheat contained in the magnetic separation tank 3, so that the wheat is fully in contact with the stirring and adsorption component 11, thereby improving the adsorption of iron impurities in the wheat by the stirring and adsorption component 11. Efficiency: After the adsorption is completed, the lifting partition 4 moves downward so that the stirring and adsorption component 11 can be smoothly moved to the top of the charging box 5 under the action of the transverse mechanism 7. At this time, the electromagnetic mechanism 13 is powered off and the stirring and adsorption component 11 stops rotating, the magnetic force disappears, and the iron impurities attached to the surface of the stirring and adsorption component 11 fall into the charging box 5, realizing efficient screening of iron impurities in wheat. The charging box 5 filled with impurities is slid off and replaced with a charging box 5 for loading wheat. The wheat after screening in the magnetic separation tank 3 can be concentrated in the charging box 5 for centralized transportation and processing.

[0027] The lifting partition 4 includes a hydraulic push rod 401, which is fixedly installed on the top surface of the base 1. The telescopic end of the hydraulic push rod 401 is fixedly connected to an isolation plate 402. The isolation plate 402 is arranged to fit the opening and the surface of the loading box 5. A handle 6 is fixedly installed on the surface of the loading box 5.

[0028] Specifically, the telescopic end of the hydraulic push rod 401 drives the isolation plate 402 to rise and fall. When the isolation plate 402 is close to the opening, the stirring and adsorption component 11 cannot be moved to the top of the loading box 5 under the action of the transverse mechanism 7. When the isolation plate 402 is lowered, the stirring and adsorption component 11 can be moved to the top of the loading box 5 under the action of the transverse mechanism 7. Then, the iron impurities adsorbed on the surface of the stirring and adsorption component 11 can be transferred to the loading box 5 by controlling the power on and off of the electromagnetic mechanism 13. The gripping handle 6 can quickly slide the loading box 5 off the top surface of the base 1, which is convenient for subsequent centralized processing of impurities or wheat loaded in the loading box 5.

[0029] The transverse movement mechanism 7 includes a mounting plate 701 and a moving block 705. The mounting plate 701 is fixedly mounted on the top surface of the base 1. There are two mounting plates 701 and they are arranged opposite to each other on both sides of the magnetic separation tank 3 and the handle 6. A first motor 702 is fixedly mounted on the surface of one side mounting plate 701. The output end of the first motor 702 is fixedly connected to a threaded rod 704. The threaded rod 704 is rotatably connected to the surfaces of the two mounting plates 701. A slide bar 703 is fixedly mounted between the two mounting plates 701. There are two moving blocks 705. The moving block 705 on one side is slidably mounted on the surface of the slide bar 703, and the moving block 705 on the other side is threadedly mounted on the surface of the threaded rod 704. The mounting block 8 is fixedly mounted on the bottom surface of the moving block 705 on one side, and the structure box 9 and the component box 10 are fixedly mounted on the bottom surface of the moving block 705 on the other side.

[0030] Specifically, the output end of the first motor 702 drives the threaded rod 704 to rotate. Since the front and rear moving blocks 705 are connected by the mounting block 8, the structural box 9, the component box 10 and the stirring and adsorption component 11, and the mounting block 8 and the component box 10 are slidingly arranged in contact with the inner wall side of the magnetic separation tank 3, the mounting block 8, the structural box 9, the component box 10 and the stirring and adsorption component 11 can only move laterally, so that the moving block 705 can only move laterally. Therefore, when the threaded rod 704 rotates, the moving block 705 threadedly installed on its surface will move left and right, thereby driving the mounting block 8, the structural box 9, the stirring and adsorption component 11 and other structures to move left and right together.

[0031] The stirring adsorption assembly 11 includes a rotating tube 111, and there are two rotating tubes 111. The rotating tube 111 on one side is rotatably mounted on the surface of the mounting block 8, and the rotating tube 111 on the other side is rotatably mounted on the front and rear side walls of the structural box 9. An adsorption roller 112 is fixedly mounted between the opposite surfaces of the two rotating tubes 111, and a scraper 113 is fixedly mounted on the surface of the adsorption roller 112.

[0032] Specifically, the rotating drive assembly 12 drives the rotating tube 111 to rotate, and the rotating tube 111 drives the adsorption roller 112 fixedly mounted on its surface to rotate, so that the scraper 113 fixedly mounted on the surface of the adsorption roller 112 rotates. When the scraper 113 rotates, it stirs the wheat, so that the wheat and the surface of the adsorption roller 112 are in full contact, and the iron impurities in the wheat are fully adsorbed on the surface of the adsorption roller 112, thereby achieving full screening of the iron impurities in the wheat.

[0033] The rotation drive assembly 12 includes a second motor 121, which is fixedly installed in the component box 10. The output end of the second motor 121 is fixedly connected to a rotating shaft 122, and the rotating shaft 122 is rotatably connected to the side walls of the structural box 9 and the side walls of the component box 10. A driving gear 123 is fixedly mounted on the surface of the rotating shaft 122, and a driven gear 124 is meshed with the surface of the driving gear 123. The driven gear 124 is fixedly mounted on the surface of the rotating tube 111.

[0034] Specifically, the output end of the second motor 121 drives the rotating shaft 122 to rotate, the rotating shaft 122 drives the driving gear 123 fixedly installed on its surface to rotate, the driving gear 123 drives the driven gear 124 meshing on its surface to rotate, and the driven gear 124 drives the rotating tube 111 fixedly connected to it to rotate, and finally drives the adsorption roller 112 and the scraper 113 to rotate.

[0035] The electromagnetic mechanism 13 includes a wire tube 131, an electromagnet body 132 and a switch circuit board 133. There are two wire tubes 131. The wire tube 131 on one side is fixedly installed on the surface of the mounting block 8, and the wire tube 131 on the other side is fixedly inserted into the surface of the structure box 9 and the component box 10 and communicates with the interior of the component box 10. The electromagnet body 132 is fixedly installed between the two wire tubes 131, and the switch circuit board 133 is fixedly installed on the inner wall surface of the component box 10. The switch circuit board 133 is electrically connected to the electromagnet body 132. The rotating tube 111 is sleeved on the outside of the wire tube 131, and the adsorption roller 112 is sleeved on the outside of the electromagnet body 132.

[0036] Specifically, the coil terminal on the surface of the electromagnet body 132 is passed through the wire tube 131 and enters the interior of the component box 10 through the wire tube 131, thereby being electrically connected to the switch circuit board 133, thereby controlling the power on and off of the electromagnet body 132 through the switch circuit board 133, controlling the timing of generating magnetic force, and realizing the adsorption and transfer of iron impurities.

[0037] In summary: by supplying power to the electromagnetic mechanism 13 to generate magnetic force, the iron impurities in the wheat are attracted to adhere to the surface of the stirring and adsorption component 11 which is mounted on the outside of the electromagnetic mechanism 13, and the stirring and adsorption component 11 is driven to rotate by the rotating drive component 12. At the same time, the transverse movement mechanism 7 drives the stirring and adsorption component 11 to move left and right, so that the stirring and adsorption component 11 can fully stir the wheat contained in the magnetic separation tank 3, so that the wheat is fully in contact with the stirring and adsorption component 11, thereby improving the adsorption efficiency of the stirring and adsorption component 11 on the iron impurities in the wheat. After the adsorption is completed, the lifting partition 4 moves downward so that the stirring and adsorption component 11 can be moved to the top of the charging box 5. At this time, the electromagnetic mechanism 13 is powered off and the stirring and adsorption component 11 stops rotating, the magnetic force disappears, and the iron impurities attached to the surface of the stirring and adsorption component 11 fall into the charging box 5, thereby realizing efficient screening of iron impurities in wheat.
