Abstract
The utility model discloses a kind of screw extruders with thickening function, including feeding valve, thickening feed bin and screw extruder, feeding valve is connected to the top left side of thickening feed bin by pipeline, the top right side for viscosifying feed bin is equipped with the first vacuum orifice, the first blender is arranged in the inside for viscosifying feed bin, the bottom of thickening feed bin connects cutting-off valve by pipeline, cutting-off valve connects buffer bin by pipeline, second vacuum orifice is set at the top of buffer bin, second blender, buffer bin bottom connecting screw extruder are set inside buffer bin.The blender of feed bin runs at high speed, friction generates heat, it is extracted PET raw material surface moisture vaporization, raw material is set to carry out polymerization reaction by vacuumizing the heat for making the vaporization of the EG in raw material be extracted and stir generation, increase viscosity, two groups of thickening feed bin cross-over designs, there are enough times to polymerization reaction, it is buffered again by buffer bin, has guaranteed continuous production.
Description
Technical field
The utility model belongs to materiel machining field, and in particular to a kind of screw extruder with thickening function.
Background technique
Screw extruder is the pressure and shearing force generated by screw rod rotation, and material can be allowed sufficiently to carry out uniformly
Mixing.PET belongs to hot melt plastic, and usual recycled PET material will use screw extruder, and Screw Extrusion is revolved by heating melting
Turn to squeeze out PET solution, then link the PET industries such as spinning, granulation or membrane, the moisture contained in raw material will lead to PET and generate water
Solution reaction, while the EG in melting process in raw material will lead to PET raw material and generate thermal degradation reaction, both side effects can make
The viscosity of PET melt reduces, to affect the quality of end product, and silo design is single is difficult continuous production.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of screw extruder with thickening function.
The utility model is achieved through the following technical solutions: a kind of screw extruder with thickening function, including
Feeding valve, thickening feed bin and screw extruder, the feeding valve are connected to the top left of the thickening feed bin by pipeline
Side, the top right side of the thickening feed bin are equipped with the first vacuum orifice, and the first blender, institute is arranged in the inside of the thickening feed bin
The bottom for stating thickening feed bin connects cutting-off valve by pipeline, and the cutting-off valve connects buffer bin by pipeline, described slow
The second vacuum orifice is arranged in slug the top of the warehouse, and the second blender is arranged inside the buffer bin, and the buffer bin bottom connects
Connect screw extruder.
Preferably, the thickening feed bin is respectively set in the left and right sides at the top of the buffer bin.
Compared with prior art, the utility model has the beneficial effects that
1, the blender of feed bin runs at high speed, and friction generates heat, takes out PET raw material surface moisture vaporization
Out, reach predrying effect
2, raw material is made to carry out polymerization reaction by vacuumizing the heat for making the vaporization of the EG in raw material be extracted and stir generation,
Increase viscosity
3, two groups of thickening feed bin cross-over designs, to polymerization reaction, there are enough times, then are buffered by buffer bin, have protected
Demonstrate,prove continuous production.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In attached drawing: 1. feeding valves；2. the first vacuum orifice；3. viscosifying feed bin；4. the first blender；5. cutting-off valve；
6. buffer bin；7. the second vacuum orifice；8. the second blender；9. screw extruder.
Specific embodiment
Such as a kind of screw extruder with thickening function shown in FIG. 1 in Figure of description, including feeding valve 1, increasing
Sizing storehouse 3 and screw extruder 9, feeding valve 1 are connected to the top left side of thickening feed bin 3 by pipeline, viscosify the top of feed bin 3
The first vacuum orifice 2 is equipped on the right side of portion, the first blender 4 is arranged in the inside of thickening feed bin 3, and the bottom of thickening feed bin 3 passes through pipe
Road connects cutting-off valve 5, and cutting-off valve 5 connects buffer bin 6 by pipeline, the second vacuum orifice is arranged at the top of buffer bin 6
7, the second blender 8,6 bottom connecting screw extruder 9 of buffer bin are set inside buffer bin 6.
A kind of screw extruder with thickening function in the implementation case, the 6 top left and right sides of buffer bin are set respectively
Set thickening feed bin 3.
Concrete operating principle: equipment run when, PET raw material by feeding valve 1 enter thickening feed bin 3, thickening feed bin 3 by
First vacuum orifice 2 connection vacuum pump group is vacuumized, and under the running at high speed of the first blender 4, friction generates PET raw material
Heat, so that the EG vaporization in PET raw material surface moisture and PET raw material is extracted, so that raw material carries out polymerization reaction, when
After viscosity increase to a certain extent, buffer bin 6 is delivered to by cutting-off valve 5 continues through the second blender 8 and be stirred
Vacuumize process is carried out with the second vacuum orifice 7, finally by 9 melting extrusion of screw extruder, by using two thickening feed bins
3, intersection carries out guaranteeing quantity-produced stability.
In conclusion the preferred embodiment of only the utility model, is not used to limit the utility model implementation
Range, all equivalent changes according to carried out by shape described in the utility model claims range, construction, feature and spirit with repair
Decorations, should be included in the scope of the claims of the utility model.
