Abstract
The invention discloses a screw feeder and particularly relates to the screw feeder for producing active pharmaceutical ingredients. The screw feeder comprises a right smashing shaft, a left smashing shaft, a right screw shaft, a left screw shaft, a hopper, a delivery pipe and an iron frame for supporting, wherein the right smashing shaft, the left smashing shaft, the right screw shaft and the left screw shaft are fixed by a support seat plate, the motor is connected with a half coupling, one end of the delivery pipe is provided with an end cover connected with a flange A and a gasket C, and a blanking connection pipe is installed at the tail end of the delivery pipe. The screw feeder is reasonable in mechanism, efficient in work and suitable for production of the active pharmaceutical ingredients.
Description
Technical field
The present invention relates to a kind of screw feeder, refer in particular to a kind of production of raw medicine screw feeder.
Background technology
The principle of work of screw feeder is: for thicker material (average diameter of particles 90 μ m), common trapezoid spiral, pressure spiral, twice relaxed helix, three line screw feeding bars can both be realized feeding in raw material preferably (1).Wherein, pressure screw feeding bar flow is little than other several screw feeding bars, is easy to realize Small Flow Control (0.1-0.6g/min); (2) for thinner material (average diameter of particles 40 μ m), owing to common trapezoid spiral, pressure helical feed power deficiency, so that blanking has intermittently, the not generation of blanking phenomenon.And twice relaxed helix, three line screw feeding bars can be realized blanking preferably.The reinforced characteristic of twice reinforced bar of relaxed helix is better than three line screw feeding bars, and flow less (0.4-0.1g/min); (3) for the reinforced realization of the low discharge object particle of subparticle, mainly be the contradiction between carrying capacity and the friction drag.The reinforced bar parameters such as pitch, line number, helical pitch, spiral form, lead angle are all influential to reinforced characteristic.
The having relatively high expectations of used screw feeder in the existing production of raw medicine, but often there is the irrational phenomenon of project organization in the screw feeder that uses at present, causes its work efficiency not high, affects manufacturing schedule.
Summary of the invention
The object of the invention is to provide a kind of production of raw medicine screw feeder of rational in infrastructure, efficient work.
Technical scheme of the present invention is: comprise by supporting seat board fixing right crushing shaft, left crushing shaft, right-hand screw axle and left-hand screw axle, hopper, conveying pipeline, motor links to each other with half a coupler, end at conveying pipeline is provided with the end cap that links to each other with flange A, packing ring C, the end that is installed in conveying pipeline is taken in blanking, also comprises for the brandreth that supports.
Wherein, above-mentioned crushing shaft links to each other with half a coupler by gear A, gear B, gear C and gear D with screw shaft, and rolling bearing units A and rolling bearing units B are installed between the gear, is provided with seal ring A, seal ring B, packing ring A and packing ring B in the junction.
Above-mentioned seal ring A and seal ring B are rotating lip-type sealing rings.
Described motor is cycloid direct connection electromagnetic adjustable speed motor.
Described blanking adapter and conveying pipeline are installed in vertical direction.
Mechanism of the present invention is reasonable, and efficient work is suitable for the production of bulk drug.
