Description

Technical Field

[0001] The invention relates to the technical field of rice processing and impurity removal machines, in particular to an air separation and impurity removal machine for rice processing. Background Art

[0002] After a series of industrial processing, rice can be quickly formed into rice. The collected rice contains a lot of dust, rice husks and impurities. In the initial processing, it is necessary to use a de-impurity machine to remove other substances mixed in the rice to improve the quality of the rice so that it can be processed into cleaner rice in the later stage. Other substances mixed in the rice can be quickly and effectively removed by wind selection;

[0003] The application number is CN202122250665.6, which is a grain impurity removal and air separation machine, comprising a feed hopper and a replaceable grain separation screen, wherein the grain separation screen is arranged at the bottom of the feed hopper; an elevator, comprising a receiving hopper, a spiral lifting mechanism and a discharge nozzle, wherein the receiving hopper is arranged at the discharge end of the grain separation screen; the utility model is suitable for various granular crops such as soybeans, corns, and rice, and the impurity-removed grains can be lifted and sent out from the discharge nozzle by the elevator, and can be used in conjunction with equipment such as a rice milling machine, so that the impurity-removed grains such as rice can be lifted and transported to the rice milling machine for grinding, thereby avoiding repeated transportation of grains between the two processes of impurity removal and grinding, and greatly reducing the work intensity. However, in the process of impurity removal, the grain impurity removal machine is not convenient for dispersing the impurity selected by air, and the grains are mixed and distributed with each other. In the process of air selection, the range of wind blowing is limited, and some other substances mixed in the grains are not convenient to be blown out and separated, which affects the effect of air selection and impurity removal;

[0004] The application number is CN201922440029.2, which is a rice processing wind selection and impurity removal device, comprising: a working platform, two groups of support frames, a processing chamber, a driving component and an impurity removal component, wherein the two groups of support frames are fixedly arranged on both sides of the upper surface of the working platform, the processing chamber is sleeved inside the two groups of support frames, and the two groups of support frames are rotatably connected to the processing chamber through bearings, a feed pipe is installed on one side of the top of the processing chamber, and the driving component is installed outside the processing chamber; the overall structure of the utility model device is simple, and the rice can be screened and cleaned quickly, which reduces the work The invention reduces the labor intensity of personnel and avoids the shortcomings of the traditional screening device with large volume and complicated operation. By providing an impurity removal component, when the processing chamber is centrifugally rotated, dust and other light materials are driven to be separated from the rice, and then the ventilation pipe is ventilated to blow out the dust and the like separated from the rice. The overall operation is convenient. However, the wind separation and impurity removal equipment only uses wind screening to separate other substances mixed in the rice during the processing process. It is not convenient for the equipment to process again the impurities that are not removed by the wind separation, and its impurity removal method is relatively limited.

[0005] Some existing air separation and impurity removal machines are not convenient for dispersing rice grains during processing. The rice grains are piled up and distributed together, which easily blocks the rice and impurities on the inner side from being separated by wind, affecting the effect of air separation and impurity removal. In addition, some existing air separation and impurity removal machines only remove rice impurities by air separation during use. The impurity removal method is relatively single, which affects the processing and impurity removal quality of rice processed in large quantities.

[0006] Therefore, it is necessary to design a wind separation and impurity removal machine for rice processing in view of the above problems. Summary of the invention
