Abstract
The utility model discloses a single screw extruder which comprises an extruder cylinder, a motor, a reduction gearbox, a feeding hole and a screw rod, wherein a hollow hole core part is arranged on the screw rod; a graphene covering layer is arranged on the hollow hole core part. The single screw extruder is good in cooling effect, low in electric energy loss and low in cost.
Description
Technical field
The utility model relates to plastic pipe extruder field, relates in particular to a kind of single screw extrusion machine.
Background technology
In the industry of traditional plastic extruder, due to extruder in the course of the work, the friction of screw rod and powder produces more heat and makes screw rod produce a large amount of temperature, therefore need to it, to carry out cooling in time, and traditional type of cooling has two kinds: a kind of employing is passed through the end of pipeline flow-direction screw rod by water or oil simply, and then flowing back to pipeline, the annular space between screw core is discharged; Another kind is self-circulation type, in screw rod endoporus, seals cooling medium, utilizes the evaporation of medium and condensation to carry out temperature control.Although to a certain degree starting cooling effect, still there is its defect in above-mentioned two kinds of types of cooling, first kind of way easily cause chilling and cooling effect poor; The shortcoming of the second type of cooling is for cannot realize external control, and therefore, the above-mentioned type of cooling cannot adapt to the needs of actual production.And this device need to configure expensive core mold oil temperature machine, has increased production cost.
As shown in Figure 2, a kind of traditional plastics list screw core deep fat cooling system, oil formula die temperature controller 7 produces oil return power, oil circuit through reducing bend 8 and reducing oil adapter 9 is supplied to oil inlet pipe 10 oil, temperature control oil flows out from oil inlet pipe 10, enters the space between oil inlet pipe 10 and screw rod inwall, shearing section, produces too high heat disturbance to oily formula die temperature controller 7, after this die heater carries out cooling processing to deep fat, recirculation fuel feeding is given single screw rod.The deep fat type of cooling that this is traditional, need to carry out accurate processing to reduction box, screw rod, and this equipment assembling process is complicated; Meanwhile, need to install a set of oil type die heater 7 additional, increase a large amount of manufacturing costs, owing to being that the mode by deep fat is delivered to oil type die heater 7 and carries out cooling processing heat, thereby lose a large amount of heats, waste electric energy.This conventional method advocate energy-conservation, lower consumption, fall cost, the age of industrial upgrading is obviously the paces that are out of step with the times.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of good cooling results, electric energy loss is little, cost is low single screw extrusion machine.
The utility model is achieved through the following technical solutions:
A single screw extrusion machine, comprises machine barrel, motor, reduction box, charging aperture and screw rod, and described screw rod is provided with emptying aperture core, and described emptying aperture core is provided with a layer graphene cover layer.Graphene is a kind of brand-new heat conduction and heat radiation material, has unique grain orientation, along both direction uniform heat conduction, and the super-high heat-conductive performance within the scope of 150-1500 W/m-K.When screw rod is in high speed rotating and plasticizing time, produce a large amount of shear heat, utilize this heat conductivility of Graphene, other temperature that shear heat moment is delivered to screw rod are this shearings section lower place relatively, thereby reaches the temperature equalization of whole screw rod.
Further, described screw rod comprises feeding section, shears section, barrier screen and mixing section, and described emptying aperture core is established the mixing section to screw rod.The utility model has reduced a set of oily formula die temperature controller, has reduced a large amount of exchanges of heat and the waste of energy that produces; Reach saving cost, reduce the object of electric energy loss.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) good cooling results, the temperature equalization of whole screw rod, can not produce chilling phenomenon;
(2) power consumption is little, cost is low; The utility model has reduced a set of oily formula die temperature controller, has reduced a large amount of exchanges of heat and the waste of energy that produces.
Figure of description
Fig. 1 is structural representation of the present utility model; Wherein, 1, core emptying aperture; 2, screw rod; 3, mixing section; 4, charging aperture; 5, reduction box; 6, machine barrel;
Fig. 2 is a kind of traditional plastics list screw core deep fat cooling system structure schematic diagram, wherein, and 7, oily formula die temperature controller; 8, reducing bend; 9, reducing oil is taken over; 10, oil inlet pipe.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is made further and being elaborated, but embodiment does not limit in any form the present invention.
Embodiment 1
As shown in Figure 1, Graphene core heat transmits a balanced screw rod, comprises machine barrel 6, reduction box 5, charging aperture 4 and screw rod 2, and screw rod 2 is provided with core emptying aperture 1, the core emptying aperture 1 of screw rod 2 is fabricated onto the mixing section 3 of screw rod 2, plates one deck grapheme material in screw core emptying aperture.Graphene is a kind of brand-new heat conduction and heat radiation material, has unique grain orientation, along both direction uniform heat conduction, and the super-high heat-conductive performance within the scope of 150-1500 W/m-K.When screw rod 2 is in high speed rotating and plasticizing time, produce a large amount of shear heat, utilize this heat conductivility of Graphene, other temperature that shear heat moment is delivered to screw rod 2 are this shearings section lower place relatively, thereby reaches the temperature equalization of whole screw rod.The utility model patent, has reduced a set of oily formula die temperature controller, has reduced a large amount of exchanges of heat and the waste of energy that produces; Reach saving cost, reduce the object of electric energy loss.
Claims (2)
1. a single screw extrusion machine, comprises machine barrel, motor, reduction box, charging aperture and screw rod, it is characterized in that, described screw rod is provided with emptying aperture core, and described emptying aperture core is provided with a layer graphene cover layer.
