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, the radial lever of 15-, 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: helical axis 8 is provided with helical blade, the head end top of shell 10 is communicated with hopper 9, the tail end of shell 10 and spray that cavity 2 is movable to be connected, the tail end spraying cavity 2 is provided with stuff-spraying pipe 1, and the afterbody outer wall of shell 10 is provided with interlayer cavity 7, chamber, interlayer cavity 7 side wall is provided with air inlet pipe 12, and its opposite side chamber wall is communicated with injection cavity 2 by tracheae 6; The tail end of helical axis 8 is provided with threaded shaft section 13, threaded shaft section 13 is provided with pressing plate 5, spring 4 and clamping sleeve 3, the end face of pressing plate 5 is provided with axial lever 16, the cylindrical wall of clamping sleeve 3 is provided with radial lever 15, radial lever 15 and axial lever 16 corresponding.
Spiral shaft part 13 is provided with locking nut 14, the fastening clamping sleeve 3 of locking nut 14, 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 greater than the tail end internal diameter of shell.
Be matched in clearance between pressing plate 5 and threaded shaft section 13, can move, for being threaded between clamping sleeve 3 with threaded shaft section 13; The cylindrical wall of clamping sleeve 3 is arranged at intervals with through hole (not shown in FIG.).
The tail end of helical axis 8 is optical axis section, does not arrange helical blade.The length of optical axis section is 8-15mm, and the diameter of optical axis section 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, the temperature of corresponding reduction shell 10 and helical axis 8, decrease high temperature power, gases at high pressure are entered by tracheae 6 and spray cavity 2, are sprayed by powder accelerator from stuff-spraying pipe 1.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 finally forms the impact capacity of resisting 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 transferred away and its density also increases.Second is that the port of export of helical axis designs the optical axis section that one end does not have flight, the diameter of optical axis section is less than the diameter of helical blade, promote owing to there is no helical blade, when material reaches this position, its proal speed will be relatively slow, so the density of granular material will increase further, in order to the unconfined increase of the density being unlikely to granular material, even block, so the designed distance of this section should be suitable, will be taken away by advancing material itself if any the material be bonded on helical axis overcoat wall or on helical axis like this, this segment distance is very short, but, the efficiency increasing material density is but very high, 3rd is spring supercharging, by adjustment spring to the size of platen pressure, the granular material finally realizing whole screw propulsion system forms the ability that more stable resistance gases at high pressure impact.
The above is only preferred embodiment of the present utility model, and not do any pro forma restriction to the utility model, every any simple modification done according to technical spirit of the present utility model, all still belongs in the scope of technical solutions of the utility model.
