Description
Technical field
The utility model relates to a kind of heater more particularly to a kind of attraction-iron type electric heaters.
Background technique
The heat transfer form of infrared ray is radiant heat transfer, transmits energy by electromagnetic wave.It is irradiated to and is heated in far infrared
When object, a part of ray is reflected back, and a part is pierced over.When the far infrared wavelength and heating object of transmitting
Absorbing wavelength it is consistent when, the object that is heated absorbs far infrared, and at this moment, interior of articles molecule and atom occur " altogether
Vibration " --- strong vibration, rotation are generated, and vibration and rotation increase object temperature, have achieved the purpose that heating.Infrared ray
Heater is used to heat for other equipment, and heating rate is fast, easy to use.Such as large-scale tower, high-pressure bottle and pipeline, Large Steel
Structure beam column, the welding preheating of various casting forgings, postwelding disappear hydrogen and annealing etc., very widely used.
Current existing heater generally uses the monomer unit of rigid structure or set composite in the majority, has a disadvantage in that:
When auxiliary applied to ship, chemical pipeline, special equipment, container or the interior workpiece in narrow space region etc. heats, on
State heater there is veneer be not easy, poor contact the problem of, cause heating efficiency low.Simultaneously because Conventional heaters are universal
Line short is caused due to favorite outer or misoperation of constructing at the scene using 220V voltage, because 220V voltage is dangerous
Voltage, once it is short-circuit, great security risk can be brought to site operation personnel, jeopardize personal safety.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems, provides a kind of attraction-iron type electric heater, work electricity
Hazard to person will not be caused to site operation personnel its advantage is that heating speed is fast, voltage security for direct current 36V by pressing.It is suitable for
Naval vessel component, segmentation, berth combination, building berth install the automatic welding in each stage, the preheating of the various opposite joints of hand weldering and corner connection seam, layer
Hot, rear heat.120 DEG C of preheating before welding keeps between road 120 DEG C of temperature in welding process, weld interruption or turn immediately when terminating
250 DEG C of heat after entering, temperature control range are that weld seam both sides are respectively not less than 100mm.Attraction-iron type electric heater is welded for warship marine high strength steel
It connects, there is extensive adaptability.
The utility model achieves the above object through the following technical schemes:
Shell and several heating units for being mounted on interior of shell including a side opening, the electricity between each heating unit
Enter end with automatic control cabinet after source connection to connect, be connected between adjacent heating unit for crawler type；It is encapsulated in heating unit
Interior calandria is nichrome wire, and the surface of each heating unit is all covered with alumina ceramic insulating layer；The shell
The another back side is equipped at least one handle, and the both ends of the handle are reserved with magnet mounting hole.
It is connected between heating unit using crawler type, can make entire heater that there is flexibility, to have very strong peace
Fill adaptability；Intensity is high, and the good alumina ceramic layer of heat-radiating properties makees insulating materials, and heater makes of nichrome wire,
Nichrome wire is not only softer, and has very high intensity, and nichrome wire connects with conducting wire, wears the heating list connected
Member installation inside the shell, installs terminal box and quick plug additional outside the shell, and heater connect with control coordinative composition of equipments and constitutes
Complete heat treatment system.When being heated, shell aperture side is bonded with workpiece is heated, magnet one end is fixed on
Handle end, the other side, in workpiece surface, are tightly fastened heater with workpiece by magnetic connection.When changing heating location,
As long as dismantling lower magnet, traveling heater is convenient to by handle.
Further, a kind of attraction-iron type electric heater shell is zinc-plated steel shell, smooth in appearance, intensity height.
Further, handle side is provided with high-temperature resistant thermal insulating material in the shell.
Preferably, the high-temperature resistant thermal insulating material is aluminium oxide ceramics.
Further, the middle of the handle is coated with heat-barrier material.
Preferably, the heat-barrier material is alumina silicate heat-preservation cotton.
Further, the handle is connected through a screw thread with shell.
The utility model has the beneficial effects that:
1, operating temperature height, quick heating, the thermal efficiency are high, pollution-free, homogeneous heating is accurate, may be implemented to automatically control.
2, operating voltage is direct current 36V, and voltage security will not cause hazard to person to site operation personnel.
3, high mechanical strength, hot good insulation preformance is big with heating object contact level, long service life.
4, installation, maintenance is convenient, and conveniently moving, cost of use is low, even if inner heat material damage, and external ceramics
Device still can reuse.
5, the utility model can make according to workpiece size, and hot face temperature is up to 1050 degrees Celsius.
