Description

Technical Field

[0001] The utility model belongs to the technical field of rice husk cleaning, in particular to a rice husk processing wind screen type cleaning machine. Background Art

[0002] Rice husk is the largest byproduct of rice processing, accounting for about 20% of rice by weight. Its main components are cellulose, lignin and silicon dioxide, and it also contains a small amount of fat, protein and minerals. Rice husk has a wide range of uses, mainly in energy utilization, feed processing and winemaking auxiliary materials. In order to effectively remove dust, fine impurities, chaff, etc. mixed in the rice husk during rice husk processing, so as to make the obtained rice husk purer, a wind screen cleaner is required.

[0003] The wind screen cleaning machine is a kind of equipment used for rice husk processing. It removes impurities in rice husks by wind selection and screening to improve the quality of rice husks. The wind screen cleaning machine usually consists of a feed port, a fan, a screen, and a discharge port. The feed port is used to feed rice husks into the equipment, the fan provides airflow, the screen performs screening, and the discharge port discharges the screened rice husks. The screen cleaning machine uses the airflow generated by the fan to blow up the rice husks so that they can be screened on the screen. At the same time, the vibration of the screen can help remove impurities and improve screening efficiency.
