Description

Airflow crushing device for pharmaceutical raw materials

Technical Field

The utility model relates to the technical field of pharmaceutical equipment, in particular to a jet milling device for pharmaceutical raw materials.

Background

A fluidized-bed airflow pulverizer for pulverizing the dry material by high-speed airflow is composed of pulverizing nozzles, classifying rotor, spiral feeder, etc. the material is fed into pulverizing chamber by spiral feeder, and the compressed air is jetted to the pulverizing chamber by specially-configured supersonic nozzle at high speed for accelerating the material in the jet of supersonic nozzle and impacting and colliding repeatedly at the intersection of nozzles. The crushed material enters the grading chamber along with the ascending airflow, and the grading rotor rotates at high speed, so that the particles are subjected to both the centrifugal force generated by the grading rotor and the centripetal force generated by the airflow viscosity, when the centrifugal force is greater than the centripetal force, the coarse particles above the grading diameter return to the crushing chamber to be continuously impacted and crushed, the fine particles below the grading diameter enter a cyclone separator and a catcher along with the airflow to be collected, and the gas is discharged by a draught fan.

In jet mills (fluidized bed jet mills), compressed air is accelerated by a laval nozzle into a supersonic gas stream and then injected into a milling zone to fluidize the material (the gas stream expands to form a fluidized bed and the fluidized bed is suspended and boiled and collides with each other), so that each particle has the same motion state. In the comminution zone, the accelerated particles collide with one another at the point of intersection of the nozzles for comminution. The crushed material is conveyed to a grading area by ascending air flow, fine powder meeting the requirement of the granularity is screened out by a horizontally arranged grading wheel, and coarse powder not meeting the requirement of the granularity returns to the crushing area for continuous crushing. The qualified fine powder enters a high-efficiency cyclone separator along with the airflow to be collected, and the dust-containing gas is discharged into the atmosphere after being filtered and purified by a dust collector.

Technical staff probably meets the process of release pressure when adding bulk drug, like this, the air current of rubbing crusher the inside can blow off bulk drug from the charge door, and bulk drug powder can disperse in the air, becomes the dust and can be inhaled the human body, leads to certain injury to technical staff, also can influence final yield simultaneously, leads to the waste of bulk drug.
