New type pressurized formula powder accelerator adding set contains spiral propeller, and spiral propeller is by shell 10 and helical axis
8 are constituted, wherein：Helical blade is provided with helical axis 8, the head end top of shell 10 connects with hopper 9, the tail end of shell 10
With injection the movable connection of cavity 2, spray cavity 2 tail end be provided with stuff-spraying pipe 1, be provided with folder on the afterbody outer wall of shell 10
Layer chamber 7, in the side cavity wall of interlayer cavity 7 air inlet pipe 12 is provided with, and its opposite side cavity wall is connected by tracheae 6 with injection cavity 2；Spiral shell
The tail end of spin axis 8 is provided with threaded shaft section 13, and pressing plate 5, spring 4 and clamping sleeve 3, the end of pressing plate 5 are provided with threaded shaft section 13
Axial lever 16 is provided with face, radial direction lever 15, radial direction lever 15 and axial lever 16 are provided with the cylindrical wall of clamping sleeve 3
It is corresponding.The helical blade of the afterbody of helical axis 8 is discontinuous structure, is constituted every spiral by helical blade is intersegmental, or by continuous
Helical blade on spaced breach 17 constitute.
Locking nut 14 is provided with spiral shaft part 13, locking nut 14 fastens clamping sleeve 3, and clamping sleeve 3 is barrel shaped structure,
Spring 4 is located 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 gap cooperation between pressing plate 5 and threaded shaft section 13, can moves, is spiral shell between clamping sleeve 3 and threaded shaft section 13
Line connects.
The tail end of helical axis 8 is light shaft part, is not provided with helical blade.The length of light shaft part be 8-15mm, light shaft part it is straight
Diameter of the footpath less than helical blade.
When using, actuating unit drives helical axis 8 to rotate, and powder accelerator is fallen on helical axis 8, in spiral shell by hopper 9
Under the drive of vane piece, powder accelerator to the tail end of helical axis 8 is moved, and powder accelerator increased density through extruding.
In addition, in course of conveying, accelerator is leaked down by the discontinuities of helical blade, extruding is produced with the accelerator for moving below, this
Sample just the helical blade of a piece of interruption can be seen off by under naturally when powder accelerator is extruded to certain density, so set by
One section longer of the relatively closely knit speed that can resist gases at high pressure will be formed between the helical blade of several interruptions of meter
Solidifying agent barrier.In the presence of spring 4 and pressing plate 5, the density of powder accelerator is further strengthened, because extruding rubs
Wipe, the temperature of shell 10 is raised, now, gases at high pressure enter interlayer cavity 7 from air inlet pipe 12, after heat exchange, heat are taken away, corresponding drop
The temperature of low shell 10 and helical axis 8, reduces high temperature power, and gases at high pressure enter injection cavity 2 by tracheae 6, by powder
Shape accelerator sprays from stuff-spraying pipe 1.In extrusion process, pressing plate 5 can only axially move on threaded shaft section 13, and can not be around
Threaded shaft section 13 is rotated, and reduces the damage of helical axis.
In order to ensure by gases at high pressure not puncturing the accelerator between helical blade in production, and and will not be because of spiral
The blade extruding undue to powder accelerator is so that abrasion is accelerated in the substantial amounts of heating of helical blade.So needing to design density
It is relatively low apart from relatively long accelerator barrier resisting the impact of gases at high pressure.With certain during in order to ensure producing
Operable space, not only have selected suitable spring strength, and make pressing plate reach one relatively to adjust clamping sleeve and spring
Suitable pressure, to tackle different accelerator materials, and other uncertain factors of production scene.
Powder accelerator material eventually forms the impact capacity of resistance gases at high pressure and should be also made up of three parts, and first is
Helical axis extruded segment, by the extruding of this section, granular material is not only conveyed out and its density also increases.Second is spiral shell
The port of export of spin axis designs one end does not have the light shaft part of flight, and the diameter of light shaft part is less than the diameter of helical blade, due to not having
There is helical blade to promote, when material reaches this position, its proal speed will be relatively slow, so powdery
The density of material will further increase, for the unconfined increase of the density for being unlikely to granular material, or even blocking, so this
One section of designed distance should be appropriate, so will be advanced by if any the material being bonded on helical axis overcoat wall or on helical axis
In material itself taken away, this segment distance is very short, but, increase material density efficiency it is but very high, the 3rd is spring
Supercharging, by adjusting size of the spring to platen pressure, the granular material for finally realizing whole screw propulsion system forms one
The more stable ability for resisting gases at high pressure impact.
The above, is only preferred embodiment of the present utility model, not makees any formal to the utility model
Restriction, every any simple modification made according to technical spirit of the present utility model still falls within the utility model technology
In the range of scheme.
