This invention discloses a feeding device for the production of hydroxyapatite
powder, aiming to solve the problems of uneven feeding, clogging, and
dust pollution caused by the poor flowability and easy agglomeration of this type of
powder. The device includes a frame, a feeding channel, a crushing device and a dust removal
assembly located within the channel. The crushing device includes a fixed rod and a movable crushing
shovel driven by a drive
assembly, effectively preventing material bridging and agglomeration through active, reciprocating
crushing action. The dust removal
assembly includes a suction chamber, a filter screen, and a cleaning roller
brush. When the crushing
shovel moves, this mechanism can be periodically actuated, driving the cleaning roller
brush to automatically clean the dust accumulated on the filter screen. This invention cleverly combines active crushing with a mechanically linked self-cleaning dust removal function, eliminating the need for an additional power source for the cleaning function. Its compact structure enables uniform, stable, and dust-
free feeding, effectively improving production efficiency and
environmental quality.
