Abstract
A direct heater of plastic and rubber comprises a material barrel (4) and an extrusion bolt (3) in the material barrel (4), which is characterized in that the body of the barrel (4) is covered and coiled with a thermal-insulation layer (5) and an inductance coil (2) electrically connected with the SB phase of a frequency-converter. The direct heating character of the utility model (using magnetic energy to convert energy) can reach more than 90% of conversion efficiency between electricity and heat energies, while the thermal-insulation layer can reduce external temperature of prior indirect heater from 600Deg. C to 80Deg. C at least. Compared with prior art, the utility model can save 40-60% electricity, reduce temperature in workshop, and improve working condition.
Description
(1) technical field
The utility model relates to a kind of plastics, rubber tooling, relates to a kind of direct firing equipment that is used for plastics, rubber processing specifically.
(2) background technology
Adopt extrusion molding or calendering formation or injection-molded no matter be in existing plastics, rubber processing method, a common ground of its processing method all is by the principle of utilizing heat exchange the material fusing to be flowed, and by physical change or chemical change moulding in period.That is to say that consumption of heat energy is one of prime cost of this series products of processing.Figure 1 shows that the firing equipment that is used for plastics, rubber processing in a kind of prior art.It comprises be equipped with on it feed hopper 1 ' barrel 4 ', be installed in the extrusion screw rod 3 of barrel 4 ' interior ' and resistance type heater 2 of being provided with around barrel '.Its operation principle be electric energy by switch S A flow to resistance type heater 2 ', resistance type heater 2 ' by the conduction, radiation mode with heat energy send to barrel 4 ', via hopper enter material in the barrel cavity utilize the heat energy of barrel be heated the back extrusion screw rod 3 ' effect under be transported to the end of barrel, extrude by mouth mould, finally become products such as mould, band, silk, sheet, pipe, rod with definite shape.The weak point of above-mentioned prior art equipment mainly is just can be utilized by conduction after electric energy must convert heat energy to.According to hot propagation formula, the big more hot-fluid of the temperature difference is big more, and the big more hot-fluid of area is big more, and indirect efficient is only about 50%.Because the temperature difference is bigger between existing resistance type heater and barrel, its heat energy reaches about 15% at the space volatile quantity, and the direct result that causes is that the thermal efficiency is low, power consumption is high, is difficult to reduce production costs.
(3) summary of the invention
The purpose of this utility model provides a kind of thermal efficiency height with regard to being to overcome above-mentioned weak point of the prior art, and energy-saving effect significantly is used for the direct firing equipment of plastics, rubber processing.
The purpose of this utility model can realize by following measure:
The direct firing equipment that is used for plastics, rubber processing of the present utility model comprises barrel, is installed in the extrusion screw rod in the barrel, the induction coil that wraps up on the cylindrical shell of described barrel, is wound with the insulation insulation material layer and is electrically connected with frequency converter SB.
The utility model also can adopt following frame mode to realize: directly parcel one deck is incubated insulating materials on the cylindrical shell of described barrel, twines the induction coil that is electrically connected with frequency converter SB outside the insulation insulation material layer.
Induction coil described in the utility model also can be arranged between cylindrical shell and the insulation insulation material layer.
Principle of the present utility model is that power frequency supply is converted to AC power about single-phase 40KHZ through converter plant, flow to induction coil, produce magnetic field, make electronics and atom high velocity impact in the barrel metal material produce the thermal vibration energy, adopt magnetic energy to carry out energy conversion, barrel is directly generated heat, and utilize the insulation insulation material layer that is wrapped on the cylindrical shell outer ring, prevent heat-energy losses the barrel insulation.
Direct heating of the present utility model (adopting magnetic energy to carry out energy conversion) feature can make electricity, heat energy conversion efficient reach more than 90%, be incubated the setting of insulation material layer in addition, the peripheral temperature of prior art indirect heated component can be reduced to from about 600 ℃ and be not more than 80 ℃.The utility model compared to existing technology, its power saving rate can reach 40-60%, and the temperature of workshop is minimized, and workman's production environment is significantly improved.
(4) description of drawings
Fig. 1 is prior art constructions figure.
Fig. 2 is a structure chart of the present utility model.
(5) specific embodiment
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
The direct firing equipment that is used for plastics, rubber processing of the present utility model comprises barrel 4 that feed hopper 1 is installed on it, is installed in the extrusion screw rod 3 in the barrel 4, on the cylindrical shell of described barrel 4, be enclosed with insulation insulation material layer 5, be wound with the induction coil 2 that is electrically connected with frequency converter SB outside insulation insulation material layer 5, frequency converter SB is connected with power supply by switch S A.
