Abstract
The present invention relates to a feeding screw rod mechanism of a dry type granulating machine, which comprises a feeding screw rod 5, a machine barrel 4 outside the feeding screw rod, a charging hopper 7 on the machine barrel 4 and an arranger 8 at one end of the feeding screw rod 5. The feeding screw rod mechanism of a dry type granulating machine is characterized in that the barrel wall of the machine barrel 4 is provided with a vacuum interface 4.1; a filter plate 3 and a pressure plate 3 are embedded inside and outside the vacuum interface 4.1; a vacuum joint 1 is spliced in the pressure plate 2. Therefore, a closed space is formed among the filter plate, the pressure plate and the machine barrel. A vacuum pump is connected with the vacuum joint to make the closed space produce vacuum, and therefore, the air in dry powders can be discharged through the filter plate. The degassed dry powders are conveyed to a next mechanism with the feeding screw rod for tabletting. The feeding mechanism completely solves the degassing problem of powders, enhances the conveying effect of materials and increases the propelling force of conveying the materials.
Description
Technical field:
The present invention relates to a kind of Drygranulatemachine, relate in particular to a kind of feeding spiro rod mechanism of Drygranulatemachine.Be mainly used in the feeding of industry dry powder prillings such as pharmacy, food, chemical industry.
Background technology:
Feeding spiro rod mechanism is the critical component of Drygranulatemachine, is used for the feed mechanism of the Drygranulatemachine of industry dry powder prillings such as pharmacy, food, chemical industry in the market, generally adopts the conical feeding spiro rod of variable pitch.In the course of conveying of material; though the conical feeding spiro rod of variable pitch can partly be sloughed the air that contains in the dry powder; but this air is discharged along screw rod appearance and machine tube inner wall gap; influenced the conveying effect of material; reduced the propulsive force that material enters next mechanism (mill roll mechanism), shortcomings such as causing that the Drygranulatemachine that is mated exists that pressure-formed slice, thin piece density is low, yield poorly when density unevenness and compacting bulk material, grain density is poor, grain density is inhomogeneous, yield rate is low.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, the feeding spiro rod mechanism of the Drygranulatemachine that a kind of air that dry powder can be contained sloughs is provided.
The object of the present invention is achieved like this: a kind of feeding spiro rod mechanism of Drygranulatemachine; the driving device that comprises machine barrel, the loading hopper on the machine barrel and screw rod one end outside feeding spiro rod, the screw rod; be characterized in offering vacuum interface on the machine barrel barrel; inside and outside screen plate and the pressing plate of being equipped with in the vacuum interface is plugged with vacuum adapter on the pressing plate.Like this, form an enclosure space between screen plate, pressing plate and the machine barrel.Vacuum pump is connected with vacuum adapter, makes to produce vacuum in this space, thereby the air in the dry powder is discharged through filter plate, and the dry powder after the degassing carries out compressing tablet with screw rod transmission to next mechanism.
This feed mechanism has thoroughly solved the degassing problem of powder; improved the conveying effect of material; strengthened the mass transport propulsive force, thereby overcome that the pressure-formed slice, thin piece density of existing Drygranulatemachine is low, yield poorly when density unevenness and compacting bulk material, shortcoming such as grain density is poor, grain density is inhomogeneous, yield rate is low.
Description of drawings:
Fig. 1 is an overall structure scheme drawing of the present invention.
The specific embodiment:
As Fig. 1, the present invention is a kind of feeding spiro rod mechanism of Drygranulatemachine.Mainly form by the outer machine barrel 4 of feeding spiro rod 5, screw rod, loading hopper 7 on the machine barrel 4 and the driving device 8 of screw rod 5 one ends etc.
On the barrel at machine barrel 4 rear portions, offer two vacuum interfaces 4.1, upper and lower being symmetrical arranged.Vacuum interface 4.1 is square.Inside and outside order is equipped with screen plate 3 and pressing plate 2 in the vacuum interface 4.1.Outer ply wood 2 usefulness screws and machine barrel 4 barrel sealing and fixing.Be plugged with vacuum adapter 1 on the pressing plate 2.Vacuum adapter 1 is connected with vacuum pump.
Whole feed mechanism is installed on the support 6.
