A fluidized-bed airbag tap rotation-preventing mechanism comprises a rotation-preventing shaft sleeve, a bearing block seat, an airbag tap, a fluidized-bed base and an airbag; the fluidized-bed base is provided with a base installation hole, the bearing block seat is provided with a bearing block seat installation hole, the bearing block seat is installed at the outer side of the fluidized-bed base and is disposed at the base installation hole, and the airbag is disposed at the inner side of the fluidized-bed base, and the airbag tap penetrates the base installation hole and is disposed in the bearing block seat installation hole; and the rotation-preventing shaft sleeve is inside provided with a rotation-preventing strip-shaped inner hole, the rotation-preventing shaft sleeve is installed in the bearing block seat installation hole and is far away from the airbag side, the airbag tap is of a circular square milled structure, and the inlet end of the airbag tap is installed in the strip-shaped inner hole of the rotation-preventing shaft sleeve. The beneficial effects comprise that the airbag tap in the circular square milled structure and the rotation-preventing strip-shaped inner hole of the rotation-preventing shaft sleeve are in wedged connection, the two parts are guaranteed to not mutually rotate around the axis, and the utility effect and the service life of the airbag are improved.
Description
technical field [0001] The invention relates to an anti-rotation system, in particular to an anti-rotation mechanism for a fluidized bed airbag nozzle. Background technique [0002] Fluidized bed technology is widely used in my country's pharmaceutical industry. Fluidized bed technology has developed from the original fluidized bed drying to fluidized bed mixing, fluidized bed coating, fluidized bed granulation (pellet) and fluidized bed pulverization. Etc., developed from the original solid preparation to other preparations in the application of preparations, especially made outstanding contributions to granulation and drying. The airbag and the airbag mouth of the traditional fluidized bed are fixed by bonding. If the force is too large, the airbag mouth and the airbag will fall off. The airbag mouth is cylindrical, and the airbag mouth may be twisted and rotated when the airbag mouth is sealed on the base , so that the air bag mouth and air bag fall off, resulting in seal...
