Description

Technical Field

[0001] The utility model belongs to the technical field of sesame magnetic separators, in particular to a magnetic separation device for sesame oil production. Background Art

[0002] Sesame oil is a seasoning oil made from sesame as raw material. In the production process of sesame oil, the raw sesame seeds need to be screened to remove impurities in the sesame seeds. In addition to screening with sieves, magnetic separation is also required to remove magnetic impurities. The magnetic separation process is usually completed with a sesame magnetic separator.

[0003] Patent application number 202320317749.3 discloses a raw sesame magnetic separator, including a box body, a guide plate, a transmission roller and a conveyor belt, etc. The magnets in the conveyor belt are used to absorb the magnetic impurities in the sesame, and a shovel head is used to shovel away the absorbed impurities.

[0004] The above-mentioned patent solution adopts a scraping method to clean the adsorbed impurities. Although it can scrape off the magnetic impurities, when the conveyor belt is in working state, the shovel head will rub against the surface of the conveyor belt, causing the conveyor belt to wear faster and shorten its service life. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a magnetic separation device for sesame oil production. In the process of magnetic separation of sesame using a conveyor belt, impurities adsorbed by the conveyor belt are separated by bags, and a fan is used to supply air to the bags to expand the bags, thereby moving the impurities away from the conveyor belt. As a result, the magnets in the conveyor belt are far away from the impurities, and the magnetic force cannot adsorb the impurities, so the impurities fall off downwards, achieving a cleaning effect. Compared with the existing scraping method, there is no friction on the surface of the conveyor belt, which avoids the phenomenon of rapid wear of the conveyor belt and extends the service life of the conveyor belt.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A magnetic separation device for sesame oil production comprises a box body, the top of the box body is provided with an opening, two rotating shafts are rotatably connected in the box body, a conveyor belt is installed between the rotating shafts, a plurality of magnets are installed in the conveyor belt, a motor is fixedly connected to the outer side of the box body, one end of the rotating shaft on the left side passes through the box body and is fixedly connected to the motor output shaft, a plurality of bags are fixedly connected to the outer surface of the conveyor belt, an air inlet pipe is connected to the opening of the bag, an end of the air inlet pipe away from the bag extends to the inner surface of the conveyor belt, a fan is fixedly connected to the outer side of the box body, an air outlet of the fan is connected to an air blowing pipe, an end of the air blowing pipe away from the fan It penetrates into the box body and extends between the upper and lower sides of the conveyor belt, and the end of the air blowing pipe faces downward and corresponds to the air inlet pipe. The bottom of the inner cavity of the box body is fixedly connected with a first baffle and a second baffle. The first baffle is located below the right side of the bottom of the conveyor belt. The top of the right side of the first baffle is fixedly connected with a guide plate, and the guide plate is inclined downward from left to right. A discharge port is provided at the bottom of the right side of the box body, and the right side of the guide plate extends to the discharge port. The second baffle is located below the left side of the bottom of the conveyor belt. A waste port is provided at the bottom of the box body between the first baffle and the second baffle, and the end of the air blowing pipe corresponds to the waste port.

[0008] Furthermore, the bag is a latex bag, and iron powder is bonded to the bottom of the inner side of the bag.

[0009] Furthermore, a slide groove is provided on the top of the second baffle plate, a spring is fixedly connected to the bottom of the slide groove of the second baffle plate, a movable plate is fixedly connected to the top of the spring and is slidably connected to the slide groove of the second baffle plate, and a movable roller is rotatably connected to the top of the movable plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. In the process of magnetic separation of sesame using a conveyor belt, bags are used to separate the impurities adsorbed by the conveyor belt, and the bag is expanded by using a fan to supply air to the bag, so that the impurities are moved away from the conveyor belt. As a result, the magnets in the conveyor belt are far away from the impurities, and the magnetic force cannot adsorb the impurities. The impurities fall off downwards, achieving a cleaning effect. Compared with the existing scraping method, there is no friction on the surface of the conveyor belt, which avoids the phenomenon of rapid wear of the conveyor belt and extends the service life of the conveyor belt.

[0012] 2. Use latex bags as bags so that the bags can be thinner and still have good elasticity, which not only avoids the influence of the thickness of the bag on the magnet to absorb impurities, but also facilitates the expansion of the bag. After the impurities on the surface of the bag fall off, the iron powder can make the lower side of the bag be affected by the magnetic force and fit with the upper side of the bag to keep the bag in a deflated state, avoiding the gas retained in the bag, making the overall thickness of the bag thicker, and causing the magnet to be unable to absorb impurities.

[0013] 3. The movable plate is pushed by the spring so that the movable roller can squeeze out the gas in the bag and make the bag deflate. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the inner cavity of the box body 1 is fixedly connected with the first baffle 10 and the second baffle 11. The first baffle 10 is located at the bottom of the right side of the bottom of the conveyor belt 3. The top of the right side of the first baffle 10 is fixedly connected with a guide plate 12. The guide plate 12 is inclined downward from left to right. A discharge port 13 is provided at the bottom of the right side of the box body 1. The right side of the guide plate 12 extends to the discharge port 13. The second baffle 11 is located at the bottom of the left side of the bottom of the conveyor belt 3. A waste port 14 is provided at the bottom of the box body 1 between the first baffle 10 and the second baffle 11, and the end of the air blowing pipe 9 corresponds to the waste port 14.

[0021] The bag 6 is a latex bag, and iron powder 15 is bonded to the bottom of the inner side of the bag 6 .

[0022] A slide groove is provided at the top of the second baffle 11, a spring 16 is fixedly connected to the bottom of the slide groove of the second baffle 11, a movable plate 17 slidably connected to the slide groove of the second baffle 11 is fixedly connected to the top of the spring 16, and a movable roller 18 is rotatably connected to the top of the movable plate 17.

[0023] Working principle: In the utility model, sesame seeds are evenly spread on the bag 6 on the upper side of the conveyor belt 3 from the opening of the box body 1, and the motor 5 drives a rotating shaft 2 to rotate, and cooperates with another rotating shaft 2 to make the conveyor belt 3 move. The magnetic impurities in the sesame seeds are attracted to the outer surface of the bag 6 by the magnetic force of the magnet 4. When the conveyor belt 3 transports the sesame seeds to the right, the sesame seeds fall onto the guide plate 12 and slide out from the discharge port 13 along with the inclined guide plate 12. The impurities continue to move with the conveyor belt 3, and the air flow generated by the fan 8 is blown out from the blowing pipe 9. When the air inlet pipe 7 on the bag 6 moves to the bottom of the blowing pipe 9, the air flow blown out of the blowing pipe 9 enters the bag 6 from the air inlet pipe 7. After the gas enters the bag 6, the bag 6 is propped up, and the lower side of the bag 6 is propped away from the upper side, so that the bag 6 is in an expanded state, and the impurities As the bag 6 expands, it is far away from the conveyor belt 3, and the magnetic force of the magnet 4 can no longer absorb the impurities, so the impurities fall and are discharged from the waste port 14. The expanded bag 6 continues to move with the conveyor belt 3, and the spring 16 pushes the movable plate 17 to have an upward trend, and then the movable roller 18 moves upward with the movable plate 17. After contacting the bag 6, the movable roller 18 squeezes the passing bag 6 while rotating, and squeezes the gas in the bag 6 out of the air inlet pipe 7. At this time, the iron powder on the lower side of the bag 6 is affected by the magnetic force of the magnet 4, so that the lower side and the upper side of the bag 6 are re-fitted, and the bag 6 is in a deflated state. Finally, the deflated bag 6 moves to the opening above the box body 1 along the conveyor belt 3, and the placed sesame seeds fall onto the bag 6 again. This cycle is repeated to achieve magnetic separation of sesame seeds.
