Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air separation equipment, in particular to air separation equipment for dry pulping. Background Art
[0002] Dry pulping involves crushing, screening, and pulverizing dry wood or other cellulose raw materials to obtain cellulose powder. Water is then added and stirred to form a slurry. This method is suitable for producing high-quality paper, but the pulp preparation process is complex and costly. Before dry pulping, the dry wood raw material must be screened. Common screening mechanisms, such as air separators, use wind power to quickly filter out impurities such as leaves and plastic bags from the lighter wood.
[0003] A winnowing machine is a device that uses airflow to transport and screen materials. Existing winnowing machines consist of a horizontally placed cylindrical housing with air inlets and outlets at the front and rear ends, and several hoppers axially positioned at the bottom of the housing. During operation, air enters through the inlet, while materials enter the housing through a feed port at the top of the housing's front end. The airflow forces materials of varying weights to fall into different hoppers, achieving the desired separation.
[0004] However, many materials are mixed with very light small particles of impurities such as dust. When these impurities are blown out by the air separator, a large amount of them float in the air. The slightest movement will cause dust to fly, causing great damage to the respiratory tract of the workers.
[0005] Based on this, this proposal proposes an air separation equipment for dry pulping. Utility Model Content
