Accompanying drawing illustrates:
Fig. 1 is the structural representation of boosting type powder accelerator adding set；
Fig. 2 is the enlarged drawing of pressing mechanism in Fig. 1；
Fig. 3 is the left view of pressing mechanism shown in Fig. 2.
Detailed description of the invention:
Embodiment: see Fig. 1-Fig. 3, in figure, 1-stuff-spraying pipe, 2-sprays cavity, 3-clamping sleeve, 4-spring, 5-pressing plate, 6-tracheae, 7-interlayer cavity, 8-helical axis, 9-hopper, 10-shell, 11-fixed mount, 12-air inlet pipe, 13-threaded shaft section, 14-locking nut, 15-radially lever, the axial lever of 16-.
Boosting type powder accelerator adding set contains spiral propeller, spiral propeller is made up of shell 10 and helical axis 8, wherein: on helical axis 8, be provided with helical blade, the head end top of shell 10 connects with hopper 9, cavity 2 is movable is connected with injection for the tail end of shell 10, and the tail end of injection cavity 2 is provided with stuff-spraying pipe 1, and the afterbody outer wall of shell 10 is provided with interlayer cavity 7, being provided with air inlet pipe 12 in the cavity wall of interlayer cavity 7 side, its opposite side cavity wall is connected with injection cavity 2 by tracheae 6；The tail end of helical axis 8 is provided with threaded shaft section 13, pressing plate 5, spring 4 and clamping sleeve 3 it is provided with on threaded shaft section 13, being provided with axial lever 16 on the end face of pressing plate 5, the cylindrical wall of clamping sleeve 3 is provided with radially lever 15, radially lever 15 and axial lever 16 are corresponding.
Being provided with locking nut 14 on spiral shaft part 13, locking nut 14 fastens clamping sleeve 3, and clamping sleeve 3 is barrel shaped structure, and spring 4 is between clamping sleeve 3 and pressing plate 5, and the external diameter of pressing plate 5 is more than the tail end internal diameter of shell.
It is matched in clearance between pressing plate 5 and threaded shaft section 13, it is possible to mobile, for threadeding between clamping sleeve 3 with threaded shaft section 13；Through hole (being not drawn in figure) it is arranged at intervals with on the cylindrical wall of clamping sleeve 3.
The tail end of helical axis 8 is light shaft part, is not provided with helical blade.The a length of 8-15mm of light shaft part, the diameter of light shaft part is less than the diameter of helical blade.
During use, actuating unit drives helical axis 8 to rotate, and powder accelerator is fallen on helical axis 8 by hopper 9, and under the drive of helical blade, powder accelerator moves to the tail end of helical axis 8, and powder accelerator, through extruding, adds density.Under the effect of spring 4 and pressing plate 5, the density of powder accelerator is further strengthened, and due to extrusion friction, shell 10 temperature raises, now, gases at high pressure enter interlayer cavity 7 from air inlet pipe 12, after heat exchange, are taken away by heat, corresponding reduction shell 10 and the temperature of helical axis 8, decreasing high temperature power, gases at high pressure enter injection cavity 2 by tracheae 6, are sprayed from stuff-spraying pipe 1 by powder accelerator.In extrusion process, pressing plate 5 can only axially move on threaded shaft section 13, and can not rotate around threaded shaft section 13, reduces the damage of helical axis.
Powder accelerator material eventually forms the impact capacity of resistance gases at high pressure and should be made up of three parts, and first is helical axis extruded segment, and by the extruding of this section, granular material is not only conveyed out and its density also increases.nullSecond is that the port of export of helical axis designs one end and do not has the light shaft part of flight，The diameter of light shaft part is less than the diameter of helical blade，Owing to not having helical blade to promote，When material reaches this position，Its proal speed will be relatively slow，So the density of granular material will increase further，In order to be unlikely to the unconfined increase of the density of granular material，Even block，So the designed distance of this section should be suitable，Material in so will being advanced by if any the material being bonded on helical axis overcoat wall or on helical axis itself is taken away，This segment distance is the shortest，But，The efficiency increasing material density is the highest，3rd is spring supercharging，By adjusting the spring size to platen pressure，The granular material finally realizing whole screw propulsion system forms a more stable ability resisting gases at high pressure impact.
The above, be only presently preferred embodiments of the present invention, the present invention not makees any pro forma restriction, every any simple modification made according to the technical spirit of the present invention, all still falls within the range of technical solution of the present invention.
