Technical field
The utility model is mainly concerned with the firing equipment field of tubulose or rod component, refers in particular to a kind of yoke formula electromagnetic induction heater that is used for tubulose or rod component.
Background technology
Many production equipments comprise tubulose and member such as shaft-like (as the machine barrel of plastic extruding forming machine and screw rod etc.), adopt the mode of outside pipeline, twining the resistance wire heating when at present these production and processings being heated with tubulose and rod component, the mode that has even adopt coal combustion more.The pipeline electromagnetism mode of heating of Chu Xianing is that electromagnetic induction coil 4 directly is wound into (as shown in Figure 5) on the pipeline 2 in recent years, under the control of electromagnetism heating controller 1, pass to the high-frequency current about 20KHz, make pipeline 2 realize heating because of producing eddy current loss and magnetic hysteresis loss.Existing this mode of heating has the following disadvantages:
(1), these mode of heatings all are earlier to pipeline 2 heating, by heat conduction heat energy is passed in the pipeline 2 then.Because heat energy more trends towards to the conduction of the big low temperature direction of the temperature difference, thereby the heat energy that said method produced has only fraction can pass in pipeline 2, and major part will pass become loss outside pipeline 2, and obvious heat energy utilization rate is not high.
(2), electromagnetic induction coil 4 directly is wound into electromagnetism mode of heating on the pipeline 2, can only the water back wall, can not heating tube in rod member, promptly this mode of heating can not heat simultaneously to tubulose and rod component.
(3), the magnetic line of force that produced of existing electromagnetic heating coil 4 is to form the loop by pipeline 2 and coil outer air, in its path approximately half by pipeline 2 as iron core, and second half is made of air, thereby the magnetic circuit magnetic resistance is big, to around electromagnetic radiation also bigger.When same pipeline 2 is wound with a plurality of electromagnetic induction coil 4, respond to high pressure because of the coupling mutual inductance easily, cause the system failure.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provide a kind of simple and compact for structure, with low cost, applied widely, heats is good, can be simultaneously to the yoke formula electromagnetic induction heater that is used for tubulose or rod component of tubulose or rod component heating.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
A kind of yoke formula electromagnetic induction heater that is used for tubulose or rod component, comprise electromagnetism heating controller and electromagnetic induction coil, described electromagnetism heating controller links to each other with electromagnetic induction coil, it is characterized in that: described electromagnetic induction coil is set around on the yoke, and described yoke is fixed on the member to be heated.
As further improvement of the utility model:
The two ends of described yoke are fixed on the outer wall of tubulose member to be heated.
The two ends of described yoke are embedded in the tube wall of tubulose member to be heated, are provided with the diamagnetic material layer between described yoke and the tube wall.
Described yoke comprises one with the upper magnet yoke group, and described yoke group comprises two U-shaped spares that are symmetrically fixed on the member to be heated.
Described yoke is wrapped on the whole outer wall of member to be heated.
Compared with prior art, advantage of the present utility model just is:
1, yoke formula electromagnetic induction heater of the present utility model, have advantages such as simple and compact for structure, with low cost, applied widely, that heats is good, can heat simultaneously tubulose and rod component, then can improve heat utilization efficiency greatly, thereby reduce energy consumption and production costs;
2, the magnetic line of force that electromagnetic heating coil produces is to form the loop by rod member in yoke, duct wall or the pipe in the yoke formula electromagnetic induction heater of the present utility model, the contained air gap in loop is little, almost form by permeability magnetic material (rod member in yoke, duct wall or the pipe), thereby the magnetic circuit magnetic resistance is little, and is little to electromagnetic radiation all around.When same pipeline is equipped with a plurality of heater, because each magnetic circuit system is independent, thereby does not have the coupling mutual inductance, can not respond to high pressure, finally can improve whole heats greatly.
