Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical solution of the utility model is described further.
A kind of cone screw mixer, including, cylinder 1, drive device 2 and helical axis 3, the cylinder 1 are tapered, described
Helical axis 3 is rotated under the effect of drive device 2, it is characterised in that also including blade 4 and charging aperture 5, the blade 4 is arranged at
The top of cylinder 1, the rotational band movable vane piece 4 of helical axis 3 rotates, and the charging aperture 5 transports material to the top of blade 4.Enter
Material mouth 5 is provided with multiple, has two kinds of set-up modes, a kind of is the vertical direction for being set directly at blade 4, and in charging, powder is straight
Connect on blade 4；It is another, above the side for being arranged on blade 4, powder is guided to blade 4 by drainage trough, such as Fig. 2
It is shown, it is a kind of common type of blade 2, but be not limited only to this.
The application method of this mixing screw is as follows：First, drive device 2 is started, driving helical axis 3 is rotated, while band
Movable vane piece 4 is rotated；Secondly, it would be desirable to which two or more powders of mixing are transported on blade 4 by charging aperture 5 simultaneously, powder
In the presence of the blade 4 of rotation, random uniformly disperses to inside cylinder 1, and the first stage is mixed in completion feeding process
Close；Then, powder is fallen into behind the inside of cylinder 1, and helical axis 3 continues to rotate, further mixed powder, and after mixing is finished, discharge is simultaneously
Shutdown.
In order to extend feeding process, prevent powder from directly being fallen into inside cylinder 1 from the space of blade 4, be additionally provided with storage
Feed bin, as shown in figure 1, the storage bin is made up of bottom plate 7 and heel post 6, the heel post 6 is provided with many, 6 liang of heel post
End is connected with bottom plate 7 and cylinder 1 respectively, gap is left between the heel post 6, the bottom plate 7 is arranged at the lower section of blade 4.
The powder of input, can be temporarily stored on bottom 7, will not directly fall into the bottom of cylinder 1.All powders, are all the blades 4 by rotation
Accelerate what is thrown away, powder is encountered after heel post 6 during throwing away, again pass by reflection and reflect, on the one hand, what it was scattered
Randomness is more preferable, so the mixed effect of two kinds of powders is just more preferable；On the other hand, for the powder for the caking that makes moist, mistake herein is understood
Smashed in journey, provide convenient for mixing below, improve mixing efficiency.
It is preferred that, blade 4 and helical axis 3 the key connection, as shown in Figure 1.
In order to obtain acceleration effect of the more preferable blade 4 to powder, as shown in figure 3, also including power transmission shaft 9, gear wheel 10
