Description

Technical Field

[0001] The utility model relates to the technical field of powder classifiers, in particular to a feeding mechanism and a powder classifier. Background Art

[0002] The powder classifier drives the 60 blades on the turntable to rotate through the speed regulating motor and the secondary reduction to form a classification effect on the powder. The speed of the blades is adjusted according to the size of the finished powder. If you want to obtain finer powder, you must increase the blade speed to increase the contact between the blades and the powder, so that the powder that does not meet the requirements is thrown to the outer wall by the blades and separated from the airflow, and the coarse powder falls into the grinding chamber for re-grinding due to the effect of gravity.

[0003] However, the current powder classifier uses a belt conveyor to load materials, and materials often leak during the loading process, causing the powder classifier to exceed the processing dust standard. After the belt conveyor is stuck, it needs to be disassembled as a whole, causing the powder classifier to stop working. The feeding point of the powder classifier is seriously blocked, making it difficult to carry out secondary crushing. Utility Model Content

[0004] The purpose of the utility model is to provide a feeding mechanism and a powder classifier to solve the problems raised in the above background technology.

[0008] Preferably, the anti-blocking mechanism comprises a conveying cylinder and built-in rotating blades, and the built-in rotating blades are movably installed inside the conveying cylinder.

[0009] Preferably, the conveying cylinder and the built-in rotating blades can be movably mounted with spiral blades, and the spiral blades spirally convey the raw materials to the inside of the conveying cylinder.

[0011] Preferably, the air pressure tube pneumatically pushes the loading box through the pneumatic pushing frame, and the loading box pneumatically enters the spiral blade to perform spiral loading.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides spiral blades and built-in rotating blades, and the spiral blades can drive the built-in rotating blades in the conveying barrel to rotate. When the raw materials enter the built-in rotating blades and the material port frame of the powder selector, the raw materials are subjected to secondary spiral conveying through the built-in rotating blades to avoid the raw materials being blocked at the material port of the powder selector.
