Abstract
Description
Technical Field
[0001] The utility model relates to the field of separation equipment for shelling sesame and removing impurities, in particular to a separation device for shelling sesame and removing impurities. Background Art
[0002] Sesame, a species of sesame, is found in tropical regions of the world. Sesame is one of the four major edible oil crops in my country and one of the main oil crops in my country. Sesame products have high application value. Its seeds contain up to 61% oil. Since ancient times, my country has had many famous foods and delicacies made from sesame and sesame oil, which have always been famous in the world.
[0003] After sesame is harvested, it needs to be shelled to form shelled sesame. Ordinary families can soak the sesame, then put the soaked sesame into a coating, and then use a small stick to hit it evenly and repeatedly until the sesame shell falls off, and then put the sesame fruit and sesame shell into the water again. Since the sesame shell has a lower specific gravity, the sesame shell will float on the upper layer of the water, while the sesame fruit will sink to the bottom of the water due to its higher specific gravity. The separation of sesame fruit and sesame shell is achieved by water selection.
[0004] In the process of industrial processing of shelled sesame, after the sesame shell is separated from the sesame fruit by industrial equipment, a mixture of sesame shell and sesame fruit is formed, and then the sesame shell and sesame fruit are completely separated by air selection to form shelled sesame products and sesame shell byproducts. The separation between sesame shell and sesame fruit by air selection equipment of sesame has the characteristics of high separation efficiency and has always been the preferred equipment for industrial processing of shelled sesame. However, according to the feedback from different customers after the product was put on the market, after the corresponding equipment transported the mixture formed by sesame shell and sesame fruit to the corresponding air selection equipment, the airflow passed through the mixture and carried the sesame shell in the mixture to the dust removal equipment. The thickness of the mixture passed by the airflow is large, thereby increasing the resistance of the sesame shell to be separated from the mixture, and then the sesame fruit after air selection still carries a large amount of sesame shell. Therefore, the air selection and separation equipment of sesame still has room for improvement in improving the separation rate of sesame shell and sesame fruit, thereby improving the separation rate of product separation of sesame fruit and sesame shell, meeting market demand, and improving product promotion.

[0024] The usage of this product is as follows: Figures 1 to 3 As shown, the following steps are included:
[0025] S1. The mixture of sesame fruits and sesame shells is transported to the raw material storage tank 16; then, the relative position of the bottom end of the limit rod 5 in the separation tank 1 is adjusted by adjusting the adjusting nut 10. During this process, the spring 8 is always connected with the first limit plate 7 and the second limit plate 9, and the spring 8 is always in a compressed state. The difference is only the difference in the amount of compression. Then, the position of the end of the adjusting plate 4 away from the first feeding pipe 2 in the guide groove 3 is adjusted to a preset range; the induced draft fan 31 and the first star-shaped discharger 17 are turned on; at this time, the mixture of sesame fruits and sesame shells in the raw material storage tank 16 is continuously discharged by the first star-shaped discharger 17. After decelerating conveying by the shaped discharger 17, the sesame seeds are transported to the separation tank 1 through the inner cavity of the first feed pipe 2 and the inner cavity between the guide groove 3 and the adjustment plate 4 to form a continuously descending material flow; at the same time, the outside air is driven by the induced draft fan 31 and then enters the separation tank 1 after filtering mechanical impurities through the filter screen 15, passing through the continuously descending material flow and carrying a large amount of sesame shells, and completes the first separation of sesame fruits and sesame shells through the first air outlet pipe 12. The airflow carries the sesame shells and is transported to the second pulse dust collector 32 for gas-solid separation. The sesame shells entering the second pulse dust collector 32 are continuously transported outward through the solid phase discharge end of the second pulse dust collector 32.
[0026] S2, the mixture after the first separation of sesame fruits and sesame shells in the separation tank 1 continues to fall to the bottom of the separation tank 1, is decelerated and transported by the second star-shaped discharger 20, and is then transported to the screening tank 23 through the connecting pipe 22 and the second feeding pipe 21 in sequence; then, the vibration motor 28 is turned on, and the material entering the screening tank 23 continues to move toward the screening tank 23 away from the second feeding pipe 21; during this period, the remaining sesame shells passing under the second air inlet pipe 26 are light in weight, and pass through the second air inlet pipe 26 together with the air flow entering the second air inlet pipe 26, thereby completing the second separation of sesame fruits and sesame shells; the sesame shells entering the second air inlet pipe 26 are transported to the first pulse dust collector 24 together with the air flow for gas-solid separation, and the sesame shells entering the first pulse dust collector 24 enter the bottom of the first pulse dust collector 24, are decelerated and transported by the third star-shaped discharger 37, and are transported to the inner cavity of the waste guide groove 38, and the sesame shells entering the inner cavity of the waste guide groove 38 are guided by the waste guide groove 38 and collected by the staff. Since the material transported outward through the screening trough 23 away from the second feeding pipe 21 undergoes a second separation of sesame fruits and sesame husks, the amount of sesame husks mixed in the sesame fruits is greatly reduced.
[0027] Through this embodiment, by adjusting the relative height of the limit rod 5 and then adjusting the relative height of the adjustment plate 4 away from the end of the first feed pipe 2 in the guide groove 3, it is possible to adjust the gap between the adjustment plate 4 away from the end of the first feed pipe 2 and the guide groove 3, and then adjust the material layer thickness of the mixture composed of sesame fruits and sesame shells transported outward through the gap between the adjustment plate 4 away from the end of the first feed pipe 2 and the guide groove 3, and combine with the airflow continuously transported by the first air inlet pipe 11 to transport the mixture outward through the gap between the adjustment plate 4 away from the end of the first feed pipe 2 and the guide groove 3, so as to realize the separation of sesame fruits and sesame shells. Since the material layer thickness of the mixture composed of sesame fruits and sesame shells transported outward through the gap between the adjustment plate 4 away from the end of the first feed pipe 2 and the guide groove 3 can be adjusted, the interaction between materials in the mixture is reduced, thereby improving the separation rate of sesame fruits and sesame shells.

Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
