Abstract
The material feeding screw mechanism for dry pelletizing machine includes material feeding screw, machine barrel outside the screw, material bin on the machine barrel and the transmission device on the end of the screw. It features the machine barrel with vacuum interface on its wall filtering plate and pressing board embedded in the vacuum interface, and vacuum joint inserted on the pressing board, with the filtering plate, the pressing board and the machine barrel constituting one closed space. The vacuum pump is connected to the vacuum joint to produce vacuum in the said space to exhaust air from the dry powder, so that the deaired dry powder is fed with the screw to the next mechanism for tabletting. The material feeding mechanism can deair the powder material completely to raise material conveying effect and enlarges the material driving force.
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 at present, generally adopts the conical feeding spiro rod of varying pitch.In the course of conveying of material; though the conical feeding spiro rod of varying 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 the slice, thin piece density of compacting 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 transmission 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 filter 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 filter, pressing plate and the machine barrel.Vavuum 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, thus shortcoming such as the slice, thin piece density that has overcome the compacting of existing Drygranulatemachine is low, yield poorly when density unevenness and compacting bulk material, grain density is poor, grain density is inhomogeneous, yield rate is low.
Description of drawings:
Fig. 1 is a general structure schematic diagram 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 transmission 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 filter 3 and pressing plate 2 in the vacuum interface 4.1.Outer laminate 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 vavuum pump.
Whole feed mechanism is installed on the support 6.
