Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder classifiers, in particular to an anti-blocking structure of a separation powder classifier. Background Art
[0002] Powder classifiers are widely used for powder sorting in the fields of building materials, food, medical treatment, metallurgy, chemical industry, etc. The cage rotor composed of multiple blades is its core component. The fan forms a negative pressure in the powder classifier chamber. After the air enters the powder classifier from the air inlet, it forms a rotating airflow driven by the high-speed cage rotor. The fine particles entering the powder classifier chamber from the feed inlet are subjected to airflow drag greater than the centrifugal force, and thus pass through the rotor blades to move toward the center of the rotor. The suction force of the fan is used to drop the fine particles into the fine powder collector, while the coarse particles are subjected to a larger centrifugal force and move toward the outer side wall. Under the action of gravity, they fall into the coarse powder collector along the side wall, thus realizing the separation of coarse and fine particles.
[0003] The above device does not have a structure to prevent coarse powder discharge from the powder classifier when in use, so that when the existing powder classifier is in use, after the powder is sorted by the powder classifier, the sorted coarse material will be discharged from the bottom pipe. However, if there is a lot of coarse material during the discharge process, the powder will easily block the coarse material discharge pipe and affect the sorting, and the coarse material is easily thrown onto the inner wall of the powder classifier during the internal rotation sorting process, and it is very easy to agglomerate after long-term accumulation. Based on the deficiencies of the existing technology, the utility model designs an anti-blocking structure for a separation powder classifier. Utility Model Content
