Abstract
The utility model discloses an electromagnetic-heating screw extruder, belonging to the technical field of plastic machinery, comprising a screw, a machine barrel, electromagnetic heaters, a protective jacket and a feed hopper, the screw is mounted in the machine barrel, the plurality of electromagnetic heaters are mounted outside the machine barrel, the protective jacket is mounted outside the electromagnetic heaters, the protective jacket is fixed with the machine barrel, and the feed hopper is mounted at the upper end of the machine barrel. The protective jacket is a double-layer stainless steel wrapper filled with asbestos therein. The type of the electromagnetic heater is LN-DV10KW. Three to five electromagnetic heaters are crosswise and uniformly distributed outside the machine barrel, and five to six electromagnetic heaters are axially and uniformly distributed. According to the electromagnetic-heating screw extruder, the machine barrel is directly heated by the electromagnetic heaters, the thermal efficiency is high and service life is long; and furthermore, the protective jacket is arranged, so that the service life can be greatly prolonged.
Description
Technical field
The utility model relates to a kind of Electromagnetic Heating screw extruder, belongs to the plastics machinery technical field.
Background technology
Screw extruder in usefulness mostly is the Far infrared electric heating device form at present, there is following problem in this mode of heating: the thermal efficiency is low, because the Far infrared electric heating device is a kind of heating system of resistance heat, its heating efficiency itself is lower, in addition because conduction is too complicated, plastics plasticizing in resistance wire → insulating barrier → shell → machine barrel, heat loss is large, and the thermal efficiency only is that energy waste is serious about 20%-30%, the Far infrared electric heating device belongs to fallible component, and spoilage is higher.In the situation that one or several heaters damages are difficult to timely discovery, cause barrel zone temperature irregular, and make product rejection.Its maintenance capacity, maintenance cost are also larger, are urgent problems therefore.
Summary of the invention
The purpose of this utility model provides a kind of Electromagnetic Heating screw extruder.
Problem to be solved in the utility model is the existing low and flimsy deficiency of the screw rod Far infrared electric heating device thermal efficiency.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of Electromagnetic Heating screw extruder; comprise screw rod, machine barrel, electromagnetic heater, protective sleeve and feed hopper; screw rod is installed in the machine barrel; machine barrel is equipped with a plurality of electromagnetic heaters outward; the electromagnetic heater outside is equipped with protective sleeve; protective sleeve and machine barrel are fixed together, and the upper end of machine barrel is equipped with feed hopper.
Described protective sleeve is the double-layer stainless steel skin, and the centre is filled with asbestos.
Described electromagnetic heater model is LN-DV10KW.
Described electromagnetic heater only laterally is evenly equipped with 3-5 at machine barrel, only axially is evenly equipped with 5-6.
The utility model has the advantages that: directly machine barrel is heated by electromagnetic heater, the thermal efficiency is high, long service life; But also be provided with protective sleeve, and can greatly increase service life, should have the wide market space.
Description of drawings
Fig. 1 is the schematic diagram of a kind of Electromagnetic Heating screw extruder of the utility model;
Fig. 2 is that the A-A of a kind of Electromagnetic Heating screw extruder of the utility model is to partial schematic diagram;
Among the figure: 1, screw rod 2, machine barrel 3, electromagnetic heater 4, protective sleeve 5, feed hopper.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure; a kind of Electromagnetic Heating screw extruder; comprise screw rod 1, machine barrel 2, electromagnetic heater 3, protective sleeve 4 and feed hopper 5; screw rod 1 is installed in the machine barrel 2; a plurality of electromagnetic heaters 3 are installed outside the machine barrel 2; electromagnetic heater 3 outsides are equipped with protective sleeve 4, and protective sleeve 4 is fixed together with machine barrel 2, and the upper end of machine barrel 2 is equipped with feed hopper 5.
Described protective sleeve 4 is the double-layer stainless steel skin, and the centre is filled with asbestos, plays insulation and the electromagnetic heater 3 of inside is played a protective role, and prevents that abominable production environment is to the destruction of inner member.
Described electromagnetic heater 3 models are LN-DV10KW.
Described electromagnetic heater 3 laterally is evenly equipped with 3 at machine barrel 2, axially is evenly equipped with 6, and such layout is so that the heating of machine barrel 2 reaches homogenising.
The using method of this device: raw material enters in the space of screw rod 1 and machine barrel 2 formation in feed hopper 5; carry out high-efficiency heating by 3 pairs of raw materials of electromagnetic heater; make the constant product quality of producing, be provided with simultaneously the service life that protective sleeve 4 can prolong whole extruder.
