[0002] The process of processing grains into rice is a series of precise operating steps, which aims to remove the husks and unnecessary parts of the grains, leaving pure, good-tasting rice grains. In the rice production process, since impurities such as rice grains need to be separated from the rice, the impurities are usually blown away by airflow, and the airflow containing impurities is filtered through a filter device. For example, the patent with announcement number CN218835217U discloses a spiral dust removal device for rice, which separates impurities such as rice husks that have not completely fallen off the rice and adhering soil, and blows out the impurities through airflow. The separated impurities and dust enter the inner side of the filter cartridge through a conduit, and the impurities and dust are filtered on the inner side of the filter screen. However, in the above technical solution, impurities are only filtered through the filter screen, and the filtering effect is limited. Utility Model Content

[0017] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0018] like Figures 1 to 4As shown, a filtering device for rice production of this embodiment includes a main body 1 and a filter 2. A filter 3 is provided in the accommodating chamber 11 of the main body 1. The accommodating chamber 11 is communicated with the air inlet 12 of the main body 1. The material enters the accommodating chamber 11 through the air inlet 12 and is filtered by the filter 3. The filter 3 is connected to the driving assembly 4, and the filter 2 is driven to rotate by the driving assembly 4. A cleaning brush 5 is provided below the filter 2, and the cleaning brush 5 abuts against the outer wall of the filter 2. The cleaning brush 5 can brush the retained impurities on the outer wall of the filter 2. A collecting box 6 is provided below the cleaning brush 5, and a spiral blade 61 is provided in the collecting box 6. The spiral blade 61 is driven by a motor 62, and the motor 62 drives the spiral blade to rotate, pushing the impurities collected in the collecting box to an outlet at one end. A filter chamber 13 is provided below the accommodating chamber 11, and a filter cartridge 7 and a filtrate are provided in the filter chamber 13. The filter cartridge 7 is at least partially in contact with the filtrate, that is, the filter cartridge 7 is partially immersed in the filtrate. The airflow enters the filter chamber 13 after passing through the filter 2, and is discharged through the air outlets 71 on both sides of the filter cartridge 7 after passing through the filter cartridge 7. In the above technical scheme, after the airflow containing impurities enters through the air inlet 12, it is filtered by the filter 2, and the impurities remain on the outer wall of the filter 2. The airflow is output through the side hole 21 of the filter 2 and enters the filter chamber 13. The airflow contacts the filter cartridge 7 for filtering again. Since the filter cartridge 7 has a filtrate, the impurities are further filtered through the filtrate, and the filtrate can be water. The filtered gas is discharged through the air outlet 71 through the exhaust port 14 on the main body 1. When there are a lot of impurities accumulated on the surface of the filter 2, they are scraped off by the cleaning brush 5, and the impurities fall into the collection box 6 and are output through the spiral blade 61. Through the above technical scheme, it is convenient to filter and collect the impurities contained in the airflow. In addition, after two filtrations, the cleanliness of the exhaust gas can be improved and the pollution can be reduced.

[0019] In this embodiment, the driving assembly 4 includes a driving shaft 41, which passes through the filter 2. One end of the driving shaft 2 is connected to the main body 1, and the other end is connected to the transmission mechanism 42. The transmission mechanism 42 is a belt drive, and the belt is driven by the motor to rotate the pulley on the driving shaft 2. This is a conventional technical means. The driving assembly 4 can drive the filter 2 to rotate, so that the cleaning brush 5 can scrape off the impurities on the surface of the filter 2. The filter 2 is cylindrical and horizontally arranged, and the outer wall of the filter 2 is arranged opposite to the air inlet 12. When the airflow enters through the air inlet 12, it contacts the outer wall of the filter 2 facing the air inlet 12 before the filter 2. When more impurities accumulate on this part of the outer wall, the outer wall facing the air inlet 12 can be replaced by rotating the filter 2.

[0020] In this embodiment, the spiral blade 61 is arranged in parallel with the filter 2, that is, the collection box 6 extends along the length direction of the filter 2, so that the impurities on the filter 2 can be collected. The filter cartridge 7 is provided with a filter portion 72, and a plurality of filter portions 72 are arranged around the rotating shaft 73 of the filter cartridge. The airflow contacts the filter portion 72, and the filter portion 72 can absorb moisture, thereby filtering the airflow. The filter portion 72 can be made of materials such as breathable fabric. The rotating shaft of the filter cartridge 7 is connected to the power mechanism 8, and the power mechanism 8 drives the filter cartridge 7 to rotate. The power mechanism 8 can use existing transmission mechanisms such as belt drive or chain drive to transmit the motor power to the rotating shaft 73 of the filter cartridge 7. The air inlet 12 is provided with an air guide plate 121, and the air guide plate 121 is arranged obliquely to guide the airflow into the accommodating chamber. There are multiple cleaning brushes 5, and multiple cleaning brushes 5 are arranged in parallel to enhance the effect of scraping off impurities.

[0021] The filtering device for rice production of the present embodiment can facilitate the filtering and collection of impurities contained in the airflow. In addition, after two filtration steps, the cleanliness of the exhaust gas can be improved and the pollution can be reduced.

[0022] It should be pointed out that the above preferred embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
