Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, specifically to a magnetic separation device for flour processing. Background Technology

[0002] During wheat harvesting, wear and tear on agricultural machinery can generate small metal fragments that may adhere to wheat grains. During transportation, such as when using conveyor belts, metal shavings from worn conveyor belt components can also get mixed into the wheat. Furthermore, the metal parts of transport vehicles, under long-term vibration and friction, can generate small magnetic particles. These particles can then accompany the wheat into the flour processing stage. In flour mills, the wear and tear on metal parts of processing equipment such as milling machines and purifiers continuously generates metal particles, which can easily become mixed into the flour.

[0003] Traditional screening mainly removes impurities by using sieves with different aperture sizes. However, it cannot remove and separate magnetic impurities that are similar in size to flour particles. Furthermore, when using air separation to separate flour, the density and suspension velocity of magnetic impurities may be very similar to those of flour. In particular, the tiny magnetic particles generated during flour processing are difficult to remove from flour by air separation, increasing the difficulty of separation. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flour processing magnetic separator, comprising a processing box configured as a rectangular three-dimensional box, a concentrated hopper installed at the upper end of the processing box, and an opening on one side of the bottom end of the processing box, wherein the opening of the processing box is penetrated by a conveyor belt, the conveyor belt being installed at the bottom of the processing box, and the concentrated hopper and the conveyor belt constituting the main structure for feeding and discharging of the flour processing magnetic separator;

[0006] The upper end of the processing box is set as a rectangular opening, and the opening at the upper end of the processing box is provided with a groove that matches the engagement of the concentrated bucket. The outer surface of the bottom end of the concentrated bucket is surrounded by a limiting plate. The bottom end of the concentrated bucket abuts against the surface of the limiting frame, and the inner wall of the processing box below the limiting frame is provided with a single-layer sloping structure.

[0007] A magnetic rod is inserted into the limiting frame, and the magnetic rod is installed in the limiting frame in a comb-like shape. The opening of the limiting frame and the part from which the magnetic rod is pulled out is larger than the diameter of the magnetic rod.

[0008] A diversion block is provided below the limiting frame, and the diversion block is set as a triangular block. A magnetic separation component is installed at the bottom of the diversion block to further adsorb metal debris from the flour diverted by the diversion block. The magnetic separation component includes: a collection box installed at the bottom of the diversion block, and a pull-out plate is slidably connected to the side of the collection box. A brush holder is installed at the strip opening on both sides of the collection box.

[0009] The above technical solution enables the device to have a two-layer magnetic separation structure, which is used to precisely purify and obtain the tiny magnetic particles remaining in the flour.

[0010] Preferably, the inner wall of the processing box is provided with another layer of sloping structure above the conveyor belt, and the end of the conveyor belt with the motor is mounted on the ground with a support foot.

[0011] By adopting the above technical solution, the material conveyor belt and external structure installation facilitate the further connection between the flour magnetic separator and the flour processing production line, thereby improving the flour production efficiency and stabilizing the flour processing production rhythm.

[0012] Preferably, the limiting frame has a through rectangular opening, and the rectangular opening of the limiting frame is aligned with the bottom opening of the concentrator.

[0013] By adopting the above technical solution, the flour in the centralized hopper is stably fed into the limiting frame, reducing waste in the production process.

[0014] Preferably, the conveyor belt and the processing box are arranged in an L-shape, and the inner wall of the processing box has two layers of sloping structures arranged vertically.

[0015] By adopting the above technical solution, the two-layer sloping structure utilizes gravity to allow the flour to slide down naturally, avoiding the accumulation and blockage of flour inside the equipment and ensuring the continuity and stability of the production process.

[0016] Preferably, the magnetic separation assembly further includes: a magnetic separator rod that is in close contact with the brush holder, and an electrically driven roller and a limiting sleeve that are close to the surface of the magnetic separator rod.

[0017] By adopting the above technical solution, the brush holder is in close contact with the magnetic separator, which allows the brush holder to clean the impurities adsorbed on the surface in a timely manner, ensuring the surface of the magnetic separator is clean and keeping the magnetic separation effect of the magnetic separator stable.

[0022] Compared with the prior art, the beneficial effects of this utility model are: This flour processing magnetic separator equipment:

[0023] 1. A double-layer magnetic separation structure is formed inside the device to thoroughly clean the tiny magnetic particles in the processed flour. By inserting a comb-shaped magnetic rod into the limiting frame, the initial falling flour can be preliminarily screened, effectively intercepting larger magnetic impurities. As the diverting block and the magnetic separation component at the bottom work further, the magnetic separation rod rotates continuously in the processing box under the coordinated drive of the electric drive roller and the limiting sleeve, which can accurately capture the tiny magnetic particles remaining in the flour. The magnetic separation rod is close to the brush frame. When rotating, the brush frame cooperates with each other to facilitate the timely cleaning of impurities from the surface, ensuring that the magnetic separation effect remains at a consistent level and stably and efficiently removing magnetic impurities from the flour.

[0024] 2. The carefully designed two-layer vertical ramp structure on the inner wall of the processing box creates favorable conditions for the flow of flour within the equipment. The ramp below the limiting frame guides the flour smoothly to the diversion block, while the ramp above the conveyor belt guides the flour to fall precisely onto the conveyor belt, reducing flour leakage. At the same time, these two ramp structures utilize gravity to allow the flour to slide down naturally, avoiding flour accumulation and blockage inside the equipment, ensuring the continuity and stability of the production process. Further, during the flour's descent, the electric drive rollers reasonably limit the flour's descent speed, further ensuring the orderly flow of flour within the equipment, significantly improving production efficiency and reducing the risk of production interruptions due to equipment failure.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-6 This utility model provides a technical solution: a flour processing magnetic separation device, including a processing box 1, a concentrator 2, a limiting frame 3, a magnetic rod 4, a conveyor belt 5, a diverting block 6, a collection box 7, a pull-out plate 8, a brush frame 9, a magnetic separator 10, an electric drive roller 11, and a limiting sleeve 12.

[0034] The processing box 1 is a rectangular three-dimensional box. A concentrated hopper 2 is installed on the upper end of the processing box 1, and an opening is opened on one side of the bottom end of the processing box 1. The opening of the processing box 1 is penetrated by the conveyor belt 5, which is installed at the bottom of the processing box 1. The concentrated hopper 2 and the conveyor belt 5 constitute the main structure for feeding and discharging of the flour processing magnetic separator.

[0035] The upper end of the processing box 1 is set as a rectangular opening, and the opening at the upper end of the processing box 1 is provided with a groove that matches the engagement of the concentrated hopper 2. The outer surface of the bottom end of the concentrated hopper 2 is surrounded by a limiting plate. The bottom end of the concentrated hopper 2 abuts against the surface of the limiting frame 3. The inner wall of the processing box 1 below the limiting frame 3 is provided with a sloping structure. The inner wall of the processing box 1 above the conveyor belt 5 is provided with another sloping structure. The end of the conveyor belt 5 with the motor is mounted on the ground with a support foot. The conveyor belt 5 and the processing box 1 are arranged in an L-shape. The two sloping structures on the inner wall of the processing box 1 are arranged vertically.

[0036] A magnetic rod 4 is inserted into the limiting frame 3, and the magnetic rod 4 is installed in the limiting frame 3 in a comb-like shape. The opening of the limiting frame 3 and the part where the magnetic rod 4 is pulled out is larger than the diameter of the magnetic rod 4. A diversion block 6 is provided below the limiting frame 3, and the diversion block 6 is set as a triangular block. A through rectangular opening is provided inside the limiting frame 3, and the rectangular opening of the limiting frame 3 is aligned with the bottom opening of the concentrator 2.

[0037] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, in use, the top of the processing box 1 is set up with the collection hopper 2, and then the conveyor belt 5 is installed inside the bottom of the processing box 1, as shown. Figure 1-2 As shown, during use, the concentrator 2 connects with the limiting frame 3, allowing flour to smoothly enter the limiting frame 3. The magnetic rod 4 inside the limiting frame 3 is inserted to separate the space within the opening of the limiting frame 3. The opening of the limiting frame 3 and the part from which the magnetic rod 4 is pulled out is larger than the diameter of the magnetic rod 4, facilitating the installation and removal of the magnetic rod 4 and ensuring full contact between the flour and the magnetic rod 4 during its descent. When the flour passes the magnetic rod 4, magnetic impurities in the flour are attracted by the magnetic rod 4, thus achieving preliminary magnetic separation and removing some larger magnetic impurities. The single-layer ramp structure located below the limiting frame 3 facilitates pushing the flour to the top of the diverting block 6. The ramp structure above the conveyor belt 5 guides the flour to fall onto the conveyor belt 5, reducing flour leakage. The ramp design allows the flour to slide down naturally in the processing box 1 by gravity, avoiding flour accumulation and blockage. The diverting block 6 is designed as a triangular block, which can evenly distribute the flour falling from the limiting frame 3 to the magnetic separator, further ensuring the smooth flow of flour, ensuring the continuity of the production process, and improving production efficiency.

[0038] A magnetic separation component is installed at the bottom of the diversion block 6 to further adsorb metal debris from the flour diverted by the diversion block 6. The magnetic separation component includes: a collection box 7 installed at the bottom of the diversion block 6, and a pull plate 8 is slidably connected to the side of the collection box 7. A brush holder 9 is installed at the strip opening on both sides of the collection box 7.

[0039] The magnetic separation assembly also includes: a magnetic separator 10 that is in close contact with the brush holder 9, an electrically driven roller 11 that is close to the surface of the magnetic separator 10, and a limiting sleeve 12. The magnetic separator 10 rotates in the processing box 1, and the surface of the magnetic separator 10 is close to the limiting sleeve 12. The electrically driven roller 11 is sleeved inside the limiting sleeve 12. The electrically driven roller 11 passes through the processing box 1, and there are two electrically driven rollers 11. The electrically driven rollers 11 are set above the material conveyor belt 5.

[0040] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the two electrically driven rollers 11 located below the diverter block 6 are as follows: Figure 2 as well as Figure 4-6As shown, the electric drive roller 11 is close to the bottom of the diverter block 6 and the opening of the processing box 1 to limit the flow rate of the falling flour. Simultaneously, the limiting sleeve 12 on the surface of the electric drive roller 11 contacts the magnetic separator 10. As the limiting sleeve 12 drives and pushes the magnetic separator 10 to rotate, it facilitates the magnetic separator 10 to re-contact the flour, achieving contact with all the flour. This allows the magnetic separator 10 to adsorb any remaining metal impurities onto its surface. As the magnetic separator 10 rotates towards the collection box 7, the brush holders 9 located on both sides of the collection box 7 are in close contact with the magnetic separator 10. Through the multi-layered brush structure on the surface of the brush holders 9, the metal impurities are separated from the surface of the magnetic separator 10. An opening is provided inside the brush holders 9 to facilitate the concentration of impurities in the collection box 7. The pull-out plate 8 inside the collection box 7 is a sloping block, facilitating the quick concentration of impurities during cleaning. By pulling the magnetic rod 4 and the pull-out plate 8, as shown... Figure 3 and Figure 5 As shown, impurities on the surface of the magnetic rod 4 are cleaned by brush, and then impurities inside the pull-out plate 8 are cleaned. A blower is used to further clean the inside of the collection box 7. The whole process does not require complicated disassembly and cleaning, which greatly reduces the labor intensity of manual cleaning.

[0041] Working principle: When using this flour processing magnetic separator, the flour is first poured into the collection hopper 2, which is funnel-shaped to facilitate the flour's concentration and smooth fall into the limiting frame 3. The magnetic rods 4 located inside the limiting frame 3 help to disperse the flour. Simultaneously, magnetic impurities in the flour are attracted by the magnetic rods 4, thus achieving preliminary magnetic separation and removing some larger magnetic impurities. The flour then passes through the diverting block 6 to flow downwards. At this time, the electric drive roller 11 drives the limiting sleeve 12 to rotate, restricting the flow rate of the flour. The rotation of the limiting sleeve 12 causes the flour to interact with the magnetic separator 10. Further contact allows the magnetic separator 10 to re-adsorb the metallic impurities on its surface. The brush holder 9 brushes the magnetic impurities adsorbed on the surface of the magnetic separator 10 to the bottom of the collection box 7 during the rotation of the magnetic separator 10, preventing the accumulation of impurities from affecting the magnetic separation effect. After screening, the flour falls into the conveyor belt 5 for outward transportation. When cleaning impurities, the magnetic rod 4 and the pull plate 8 in the collection box 7 can be pulled out to easily remove the impurities. This is convenient and quick, without the need for complicated disassembly and cleaning processes, greatly reducing the labor intensity of manual cleaning and increasing the overall practicality.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
