Technical Field

[0002] During the mechanical processing of rice, due to the normal wear of mechanical equipment, some magnetic substances such as iron sheets, iron filings, iron nails, etc. are often mixed into the rice. These substances not only affect the taste and color of rice, but also cause harm to human health. Therefore, a magnetic separator is usually used to perform magnetic separation and impurity removal operations on the rice. The magnetic substances in the rice are absorbed by the magnet rod, so that the quality of the rice is guaranteed to a certain extent.

[0003] However, when using these common magnetic separators, it was found that after the magnetic separation was completed, the machine needed to be stopped first, and then the magnet rods were removed from the rice, and the magnetic substances adsorbed on them were cleaned off before the machine could be started again for magnetic separation. The shutdown time in the middle was relatively long, so that the magnetic separation efficiency could not be improved.

[0004] Therefore, it is necessary to provide a new magnetic separation device for rice processing to solve the above-mentioned technical problems. Utility Model Content

[0024] In this embodiment, in order to reduce the force strength of the transverse screw rod 6 , a support rod is fixed in the profile frame 5 , and the support rod passes through the sliding seat 7 and is slidably connected to the sliding seat 7 .

[0025] In this method, in order to drive the two rotating shafts 9 to rotate, two motors 2 are fixed on the top inner wall of the frame 1 8, and the output shafts of the two motors 2 are respectively fixedly connected to the top ends of the two rotating shafts 9. In addition, a discharge pipe is fixed at the bottom of the magnetic separation barrel 2, on which a material valve is provided. A recess is opened on the base 1, in which a receiving barrel 12 is placed. The receiving barrel 12 is located below the discharge pipe, so that the rice after magnetic separation can be received.

[0027] The working principle of the magnetic separation device for rice processing provided by the present utility model is as follows:

[0028] When performing magnetic separation on rice, the rice to be magnetically separated is directly poured into the magnetic separation barrel 2, so that the corresponding five magnetic rods 11 are buried in the rice. Then, the corresponding motor two is started to rotate slowly, and its output shaft drives the corresponding rotating shaft 9 to rotate, so as to drive the corresponding five magnetic rods 11 to rotate. During the slow rotation process, while stirring the rice, the magnetic substances in the rice can be adsorbed. After the multiple magnetic rods 11 rotate a certain number of turns, the motor two is turned off, and at this time, the magnetic separation work is completed. Subsequently, the material valve is opened, and the rice that has undergone primary magnetic separation is discharged into the receiving barrel 12. After all the rice is discharged, the rodless cylinder 21 is started, and the slider thereon drives the U-shaped frame 5 to rise, so as to take out the multiple magnetic rods 11 located in the magnetic separation barrel 2. Immediately afterwards, the motor one is started in the forward direction, and its output shaft drives the transverse screw 6 to rotate. Then, under the threaded cooperation of the transverse screw 6 and the sliding seat 7, the frame one 8 moves horizontally. After moving to the final position, the five magnetic rods 11 that have not been used before are located above the magnetic separation barrel 2, and the five magnetic rods 11 that have been used and adsorbed with magnetic substances are located between the corresponding two semi-circular scraping strips 20;

[0029] Then, start the rodless cylinder 21 first to bring the five clean magnetic rods 11 into the magnetic separation barrel 2, then pour the rice and start the corresponding motor 2 to continue the magnetic separation work. On the other side, start the output shafts of the corresponding two telescopic cylinders 18 to extend them, so that the corresponding two clamping strips 19 are close to each other, and finally the corresponding two semicircular scraping strips 20 clamp the corresponding magnetic rod 11, and then start the corresponding motor 3 in the forward direction, and the corresponding lifting seat 16 will bring the corresponding frame 2 17 down. During the descent, the semicircular scraping strip 20 will scrape the magnetic material adsorbed on the magnetic rod 11 at one time and scrape it into the debris barrel 13 below, until the next magnetic separation work is completed, start the motor 1 in the reverse direction, replace the two groups of magnetic rods 11 again, and then continue to form a working form of magnetic separation on one side and scraping on the other side, and repeat this process.

[0030] Compared with the related art, the magnetic separation device for rice processing provided by the utility model has the following beneficial effects:

[0031] The utility model provides a magnetic separation device for rice processing. Five magnetic bars 11 are fixed at the bottom of two connecting strips 10. When magnetic separation is performed, five magnetic bars 11 are first used for magnetic separation. After the magnetic separation is completed, the positions of the two groups of magnetic bars 11 are replaced by the lateral movement of a sliding seat 7. Thus, a working state can be formed in which the rice is magnetically separated while the magnetic substances on the used magnetic bars 11 are scraped off. Thus, the downtime is interrupted to a great extent, and the magnetic separation efficiency is greatly improved.
