Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically a rice processing impurity removal device. Background Technology

[0002] Rice is a type of cereal crop. During the processing of rice, a hulling process is required to remove its outer herbaceous husk. Then, the hulled rice undergoes a purification process to remove any remaining husks and impurities, ensuring the quality of the rice.

[0003] A patent with publication number CN219702660U discloses a rice processing impurity removal device, including a box body. A connecting frame is movably connected to the upper end of the inner cavity of the box body. A filter plate is fixedly connected to the inner cavity of the connecting frame. An electric push rod is fixedly connected to the right side of the box body. The output end of the electric push rod passes through the box body and extends into the inner cavity of the box body, and is fixedly connected to a collar. This invention, through the cooperation of the electric push rod, collar, motor, and stirring frame, can fully agitate the rice, thereby improving the quality of impurity removal. The operation of a fan creates negative pressure in the suction pipe, allowing the suction pipe to draw in dust from the inner cavity of the box body. The dust is then transported by the fan to the inner cavity of a water tank, where the water absorbs the dust, thus removing it and improving the quality of rice sieving. This effectively prevents dust from passing through the screen and entering the rice, contaminating it and affecting the quality of impurity removal.

[0004] Existing rice impurity removal devices require the rice in the container to be cleaned before subsequent rice can be cleaned, which prevents continuous rice impurity removal and results in low efficiency, affecting production efficiency.

[0055] During operation, existing rice impurity removal devices require waiting for the remaining rice in the container to be cleaned before proceeding with the next batch, resulting in low efficiency and impacting production. In this solution, the drive motor 7 is controlled to rotate, which in turn drives the first gear 8, which in turn drives the first gear ring 9, causing the outer cylinder 4 to rotate within the rotating sleeve 3. The rotation of the outer cylinder 4 simultaneously rotates the first filter barrel 101 and the second filter barrel 111 within it. The first filter barrel 101… When rotating, it will drive the second gear ring 104 to transmit power to the second gear 123 inside, which in turn drives the hollow shaft 121 inside to rotate. When the second filter barrel 111 rotates, it will drive the third gear ring 114 to rotate. When the second filter barrel 111 rotates, it will drive the third gear ring 114 to transmit power to the second gear 123 inside, which in turn drives the hollow shaft 121 inside to rotate. When the hollow shaft 121 in the two sets of flipping components 12 rotates, it will rotate in the second fitting groove 53 and the first fitting groove 52 respectively, and drive the hollow plate 124 on it to rotate during the rotation.

[0056] Rice is fed into the second filter barrel 111 through the feeding pipe 14 and the feeding port 13. As the second filter barrel 111 rotates, the rice is agitated by the second guide plate 113 inside. Simultaneously, the hollow shaft 121 inside the second filter barrel 111 drives the hollow plate 124, which also agitates the rice. This, combined with the operation of the blower 19, delivers air through the hose 20 into the two hollow shafts 121 and through the slots 125 on the hollow plate 124 into both the second and first filter barrels 101. When the No. 1 filter barrel 101 rotates, the material will be turned over, further improving the turning effect on the rice entering the outer cylinder 4. During the turning process, impurities larger than the rice grain diameter will remain in the No. 2 filter barrel 111, while rice and impurities smaller than the rice diameter will leak into the No. 1 filter barrel 101. The impurities in the No. 2 filter barrel 111 will be discharged from the No. 1 discharge port 16. The rice entering the No. 1 filter barrel 101 will be turned over and screened again. At this time, impurities smaller than the rice diameter will leak into the outer cylinder 4 from the No. 1 filter hole 102. The rice after screening and impurity removal will be discharged from the No. 2 discharge port 17, while the impurities in the outer cylinder 4 will be discharged from the No. 1 discharge port 18.

[0057] This device effectively removes impurities from rice, enabling continuous impurity removal. Compared to traditional rice impurity removal devices, it has a higher impurity removal efficiency, thus significantly improving production efficiency.
