It has added materials with what the splashing of oval rotor was taken out of, above two material is mixed when screw rod rotates at this time, is improved
The mixing efficiency of material.
4, for according to the admixture of material, add materials first with part mixing material mix, then with other mixtures
Material mixing, the uniformity for the mixing that is conducive to add materials improve the quality of product.
Further, the screw position is vertical with oval rotor axial direction, and mixing material inlet is located at left banburying chamber
Highest point, mixing material outlet is located at the highest point of right banburying chamber.Because mixing material inlet is located at the highest of left banburying chamber
Place, so the indoor material of left mixing only could enter extruder barrel by mixing material inlet when being splashed to highest point
Interior, remaining material to splash is affected by gravity down drops back into left banburying chamber again, alleviates the burden of screw rod, improves making for device
Use the service life.
Further, the installation direction of the screw rod is parallel with oval rotor axial direction, mixing material inlet and mixing
Material outlet is located at the highest point of banburying chamber.The technical program reaches identical effect using different structures, improves device
Service life.
Further, the Screw Extrusion structure is parallel to each other.In same plane even with always when ensure that material transmitting
Line reduces energy consumption, has saved resource.
Further, the direction of the screw rod rotary extrusion is identical or opposite.Improve controllability.
Further, the actuator is motor, and the motor is placed in outside extruder barrel, and motor is located at screw rod radial direction
Side.Reduce the volume for squeezing out barrel, convenient for squeezing out barrel maintenance or replacement.

Specific embodiment
It is further described below by specific embodiment:
Appended drawing reference in Figure of description includes: banburying chamber 1, oval rotor 2, right banburying chamber 3, left banburying chamber 4, electricity
Machine 5, extruder barrel 6, screw rod 7, mixing material inlet 8, mixing material outlet 9, feed opening 10, top bolt 11.
Embodiment one:
Embodiment is substantially as shown in Fig. 1: a kind of mixer with Screw Extrusion structure, including banburying chamber 1, banburying chamber
There are two the oval rotors 2 of opposite revolution, two oval rotors 2 to divide banburying chamber 1 for left banburying chamber 4 for rotation connection in 1
With right banburying chamber 3, the top of banburying chamber 1 is equipped with top bolt 11, and top 11 axial sides of bolt are all placed with Screw Extrusion structure, screw rod
Squeezing out structure includes extruder barrel 6, and feed opening 10, mixing object are successively opened in the material direction of the supply in extruder barrel 6
Expect entrance 8 and mixing material outlet 9, wherein extruder barrel 6 and banburying chamber 1 are squeezed out by 8 vertical connection of mixing material inlet
By 9 vertical connection of mixing material outlet, feed opening 10 is being located at the middle part of extruder barrel 6 just for 6 tail portion of machine barrel and banburying chamber 1
Top squeezes out the screw rod 7 for being rotatably connected in barrel and placing perpendicular to oval rotor 2, and the quantity of screw rod 7 is 2, wherein one
Screw rod 7 is located between 10 mixing material inlet 8 of feed opening, another screw rod 7 be located at mixing material outlet 9 and feed opening 10 it
Between, two screw rods 7 are all connected with the motor 5 of model VTB63-4a, and 7 position of screw rod and oval 2 axial direction of rotor hang down
Directly.
Specific implementation process is as follows:
As shown in Fig. 2, when feeding for the first time, material flows successively through top bolt 11, feed opening 10, screw rod 7 and mixing material and enters
Mouth 8, when material enters banburying chamber 1 by mixing material inlet 8, operator starts mixer at this time and screw rod 7 squeezes out knot
Structure, oval rotor 2 is stirred and squeezes to material after mixer starting.Oval rotor 2 major part material in rotation
It is kneaded in banburying chamber 1, and oval rotor 2 can splash fraction material when rotated, this partial material is from mixing material
Entrance 8 enters screw rod 7 and squeezes out structure, squeezes out by screw rod 7, then reenters banburying chamber 1 by mixing material outlet 9.This
When screw rod 7 squeeze out structure complete sealing and squeeze out effect.
Sealing and extrusion due to Screw Extrusion structure, being kneaded material will not be leaked by Screw Extrusion structure.When
When needing to feed, addO-on therapy is added in Screw Extrusion structure by feed opening 10, is added materials at this time and Screw Extrusion knot
Mixing material in structure is mixed by the extrusion of screw rod 7, and then material enters in banburying chamber 1, thus reached with
When the purpose that feeds.
When subsequent charge, because of the splashing effects of oval rotor 2, newly added material is contaminated in extruder barrel 6
It has added materials with what the splashing of oval rotor 2 was taken out of, above two material has been mixed when screw rod 7 rotates at this time, according to
For the admixture of material, adds materials and first mixed with part mixing material, then be kneaded materials with other and mix, be conducive to add
The uniformity for adding material to mix.
Embodiment two:
As shown in Fig. 3, the difference between this embodiment and the first embodiment lies in, 7 position of screw rod and oval 2 axis of rotor
Parallel to direction, mixing material inlet 8 is located at the highest point of left banburying chamber 4, and mixing material outlet 9 is located at right banburying chamber 3 most
Eminence.
Specific implementation process is as follows:
Because mixing material inlet 8 is located at the highest point of left banburying chamber 4, the material in left banburying chamber 4 is only flying
It could be entered in extruder barrel 6 by mixing material inlet 8 when splashing highest point, remaining material to splash is affected by gravity down
Again left banburying chamber 4 is dropped back into, the burden of screw rod 7 is alleviated, improves the service life of device.
