Abstract
The utility model relates to a dual-screw extruder. Researches on the method that a degradation material is manufactured by starch are widely carried out in China at present, but most researches are kept at the laboratory stage and the primary test stage, and fewer researches reach the industrialization degree. The dual-screw extruder comprises a casing (5), wherein a feeding opening (14) is mounted in the casing; a weightlessness measurement hopper (1) is mounted at the feeding opening, and an exhausting opening (3) is formed in the casing; a drive shaft (4) is mounted in the casing; the end part of the drive shaft is connected with a transmission box (2); a cooling water jacket (6) is mounted on the casing; a melt pump (7), a pressure sensor (8), a filter (9) and a die head (10) are mounted at the output end of the casing; the die head is connected with an anti-dispersion cloth bag via a hook; a temperature sensor (13) is mounted at the end part of the die head. The dual-screw extruder is used for extruding starch from double screws.
Description
technical field:
the utility model relates to a kind of double screw extruder.
background technology:
make the research of degradable material extensively carries out and comes at home at present of starch, but mostly rest on laboratory and lab scale stage, the industrialization degree that can enter is little, its technological difficulties mainly contain: starch carries out after a series of modifications in the mixed reactor of height, its material become have can thermoplastic working properties material, a, very sensitive to heat: chain-scission degradation will occur if temperature is slightly high.It is dark that outward appearance shows as color, even gelatinization.B, very sensitive to pressure: if add man-hour at extruder, back pressure is crossed conference generation chain-scission degradation, outward appearance performance is the same.C, to shearing and rubbing very sensitive: if shearing force is excessive, the friction etc. between friction, material and material that material and machinery are carried, when these shearings and frictional force are excessive, also can degrade.
summary of the invention:
the purpose of this utility model is to provide a kind of double screw extruder.
above-mentioned object realizes by following technical scheme:
a kind of double screw extruder, its composition comprises: housing, on described housing, inlet is installed, weight-loss metering hopper is installed on described inlet, on described housing, have exhaust outlet, described enclosure interior is provided with driving shaft, described driveshaft end is connected with transmission case, on described housing, cooling jacket is installed, described housing output is provided with Melt Pump, pressure sensor, filter, die head, on described die head, hook is installed, described die head is connected with anti-scattered cloth bag by hook, described die head end is provided with temperature sensor.
described double screw extruder, the mixed degree refining in slow angle module is installed on described driving shaft, carry supercharging module, the equidistant degree of depth of even depth strengthen module, etc. deeply equidistant module, quantitative module.
described double screw extruder, described steam vent is two.
the beneficial effects of the utility model:
1. the utility model is double screw extruder, and the process of making biodegradation material of starch is a complicated process.He is not only relevant with the molecular chain structure of starch, but also relevant with all modified additive kinds, but particularly the process equipment of starch conversion is had to direct association especially.We have carried out years of researches to the process equipment of starch, finally invented with twin-screw in the same way extruder change the way of the mixing module combination of its screw rod, completed mass transport, plasticizing, mixing modification to starch-base biodegradation material, sheared, built the work such as compression set amount output.
2. the utility model adopts weight-loss metering hopper design, and adds temperature sensor in die head end, can carry out certain weighing to material, carries out a test of temperature at output opposite material simultaneously.
3. the dark equidistant screw rod transmission piece such as the utility model employing, the degree of depth strengthens, and places material and is subject to strong extruding and friction.
4. the utility model adopts angular transformation, and the mild mixing module of passing through is carried out mixing modification to material, reduces to shear and friction.
5. the utility model adopts equidistantly the dark screw rod module such as not to carry out screw extrusion, quantitatively output to material in twin-screw leading portion portion.
6. the utility model adopts rotating Vortex, and material is that positive 8 font motions make the suffered heat of material, mechanical friction and shear as far as possible consistent.
7. when the utility model uses, adopt hungry feed mode to avoid excessive being heated and rubbing and shear.
brief description of the drawings:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is the axle of twin-screw in the utility model and the configuration relation structural representation of module.
detailed description of the invention:
embodiment 1:
a kind of double screw extruder, its composition comprises: housing 5, inlet 14 is installed on described housing, weight-loss metering hopper 1 is installed on described inlet, on described housing, have exhaust outlet 3, described enclosure interior is provided with driving shaft 4, described driveshaft end is connected with transmission case 2, cooling jacket 6 is installed on described housing, described housing output is provided with Melt Pump 7, pressure sensor 8, filter 9, die head 10, hook 11 is installed on described die head, described die head is connected with anti-scattered cloth bag 12 by hook, described die head end is provided with temperature sensor 13.
embodiment 2:
according to the double screw extruder described in case study on implementation 1, the mixed degree refining in slow angle module 17 is installed on driving shaft, carry supercharging module 18, the equidistant degree of depth of even depth strengthen module 15, etc. deeply equidistant module 16, not etc. deeply equidistantly do not build compression set amount module 19.
embodiment 3:
according to the double screw extruder described in case study on implementation 1 or 2, steam vent is two.
