Description
Technical field
The invention belongs to the technical field to the materail tube heating, particularly relating to can be to the materail tube that has material to flow in pipe, with electric energy heating, the temp. controllable thermal material pipe of lowering the temperature with gas again.
Background technology
Thereby with heating materail tube to the materail tube that the flowable materials in the materail tube heats, be at a plurality of resistance-type heating blocks of the outer bread of materail tube now, conduct to materail tube with the heat of resistance-type heating block, and materail tube is heated.It is with air blast the resistance-type heating block to be dried that adjusting namely reduces the materail tube temperature, reduces the temperature of resistance-type heating block, indirectly reduces the materail tube temperature.Its weak point is: the heat major part of resistance-type heating block rejects heat in the ambient air, wasted heat, waste electric energy, but also to producing thermal pollution around the resistance-type heating block.If the temperature of resistance-type heating block will be raised to more than 70 ℃, then the resistance-type heating block is dangerous to the people on every side.So be that power consumption, cost are high, the adventurous technology of possibility to the technology of materail tube heating now.
Summary of the invention
The purpose of this invention is to provide the utilization rate of electrical that improves heating usefulness, reduce heating cost, when the hot operation state, the heating materail tube of High Temperature can not arranged to the people around the materail tube.
Design of the present invention is: heat with the metal tube of inductance coil to the contact material, with there being mezzanine space to pass into gas between metal tube and the non-metallic pipe metal tube is lowered the temperature, thereby make the temperature of metal tube can rise and can fall.
Structure of the present invention is:
With the inductance type heating material tube of temperature adjusting of interlayer air flow, comprise metal tube 1, it is characterized in that: also comprise the non-metallic pipe 2 that is enclosed within metal tube 1 outside, between metal tube 1 and the non-metallic pipe 2 mezzanine space 6 is arranged; Outer surface at non-metallic pipe 2 is wound with one group of inductance coil 3 at least, and the tube wall of non-metallic pipe 2 is provided with air inlet 4 and air outlet 5.Inductance coil 3 makes metal tube 1 produce eddy current and generates heat after energising, and the metal tube 1 of heating is the material in the heat transferred metal tube 1, to heating material.If the material in the metal tube 1 flows, then the temperature of metal tube 1 and material changes, temperature is low can switch on to inductance coil 3 continuously continuously, but when making the temperature of metal tube 1 be higher than the temperature of needs owing to thermal inertia, sending into cold wind from air inlet 4 flows mezzanine space 6, many heats are taken out of from air outlet 5, reduced the temperature of metal tube 1.With inductance coil 3 heating, with the mobile cold air cooling in the mezzanine space 6, thereby can regulate metal tube 1 temperature like this.Because metal tube 1 overcoat has hot non-conductor non-metallic pipe 2; then the heat of 2 pairs of metal tubes 1 of non-metallic pipe has the effect of insulation; can greatly save the power consumption of inductance coil 3; if it is to be raised to more than 70 ℃ that metal tube 1 requires; by metal tube 1 damage of high temperature, namely non-metallic pipe 2 does not have safe effect to the people that non-metallic pipe 2 can also be protected at this pipeline.
Metal tube 1 is the pipe that the metal material of inductance coil 3 heating that can be energized is made, such as steel pipe, iron pipe, copper pipe etc.Non-metallic pipe 2 is pipes that the nonmetallic materials of inductance coil 3 heating that can not be energized are made, and adds pipe that resin makes etc. such as plastic tube, glass fibre.
Metal tube 1 outer wall is provided with many air-flow guiding raised lines 7.For make gas in the mezzanine space 6 can Uniform Dispersion ground flow to air outlet 5, the raised line 7 that leads of the air-flow between air inlet 4 and air outlet 5 can be divided into a plurality of gas channels to gas with many, prevents that distinguished and admirable flows to air outlet 5 from shortest path.Be spaced apart along separate routes gas channel between many air-flows guiding raised line 7.The trend of air-flow guiding raised line 7 can be linear, waveform, spirality etc.
Many air-flows guiding raised line 7 with spiral form around metal tube 1 outer wall.This is a kind of preferred air-flow guiding raised line 7 structures, making along separate routes, the flow direction of air-flow flows around metal tube 1 outer wall, the material heat of metal tube 1 interior streamlined flow homogenizing more, also prolonged each along separate routes length of gas channel, make the cold air of unit volume can take away metal tube 1 more heat, can make the power of air blast less, save power consumption.
Outer surface at non-metallic pipe 2 is wound with the removable inductance coil 9 of many groups, between every group of removable inductance coil 9 spacing distance is arranged.Have this structure just can regulate the distances of organizing between the removable inductance coil 9, thereby adjusting inductance reach the purpose of regulating metal tube 1 temperature more.
Be connected to blast pipe on the air inlet 4, be connected to air blast on the blast pipe.Air blast is sent into the temperature that gas can be regulated metal tube 1 to air inlet 4, reaches the purpose of temperature stabilization in certain scope that makes metal tube 1.
The air-flow guiding raised line 7 of metal tube 1 outer wall highly is 4/6-5/6 of mezzanine space 6 spacings.Air-flow guiding raised line 7 these aspect ratios are fit to the most of directed flow of gas in the shunt gas channel, and fraction can exchange between different shunt gas channels again, makes the adjusting of metal tube 1 temperature more even.
The overall diameter of metal tube 1 is 10.00-20.00 centimetres, and mezzanine space 6 minimum spacings between metal tube 1 and the non-metallic pipe 2 are 0.10-0.40 centimetre, and inductance coil 3 is when 210-400 volt power supply, and the inductance of inductance coil 3 is the 50-500 microhenry.This is a kind of inductance type heating material tube that is fit to do the plastic rubber shaping machine, to the plastic material in the metal tube 1, can be heated to 400 ℃, but owing to having mezzanine space 6 heat insulation between metal tube 1 and the non-metallic pipe 2, and mezzanine space 6 also can pass into mobile cryogenic gas, so the temperature of non-metallic pipe 2 can remain on below 50 ℃, need of work there is not High Temperature near the personnel of non-metallic pipe 2.
Advantage of the present invention: non-metallic pipe is enclosed within the metal tube outside; the heat of metal tube there is the effect of insulation; thereby the utilization rate of electrical to heating usefulness improves; reduce heating cost; if the metal tube temperature will be raised to more than 70 ℃; then non-metallic pipe is enclosed within the metal tube outside and can protects heating materail tube people on every side, reaches the effect of safety in production.There is mezzanine space can send into mobile gas between metal tube and the non-metallic pipe, can heats, be incubated, cool off metal tube according to the difference of gas temperature, the metal tube temperature is regulated.Air-flow guiding raised line on the metal tube outer wall can make the mobile gas in the mezzanine space regulate more uniformly the metal tube temperature.
