The electromagnetic heating electric heating mantle of the present invention includes a shell, a belt along a hemispherical heating liner, a control circuit, a heat insulating plate and a coil, and the partial longitudinal section of the belt along the hemispherical heating liner and the longitudinal section of the heat insulating plate are both in the shape of “∏”. There are circular grooves under the respective plates, and the circular grooves with hemispherical heating liner are set in the circular grooves of the heat insulation board, and the coil is a solenoid, which is fixedly set outside the circular groove wall of the heat insulation board . The advantages and positive effects are: the eddy current generated by the coil makes the belt heat up along the hemispherical heating liner, the heating liner is a heating body, the thermal inertia is small, and the temperature of the plate surface can be rapidly raised and lowered after the power is turned on and off. The heat insulation plate is thin, and the gap between the heating tube and the coil is small, so the electromagnetic conversion efficiency is high, the electric energy is saved, the maintenance is convenient, and the service life is long. At the same time, the electric heat is completely isolated, which improves the safety performance.
Description
Technical field
The present invention relates to heater, particularly a kind of electromagnetism heating electric jacket.
Background technology
Electric jacket is oven dry, drying that is widely used in sample and the heater of making other humid tests, have that heating surface (area) (HS is big, quick heating, the flames of anger, homogeneous heating, light, be difficult for breaking advantage such as glassware.Be physics, chemistry, Biochemical Lab, the analysis room of school, the widely used liquid heating in laboratory of biology, heredity, medicine, environment-friendly laboratory and departments such as food, epidemic prevention, medical treatment and scientific research.
The electric jacket that uses at present comprises shell, control circuit, panel and heating sleeve; Wherein heating sleeve with the nickel-cadmium resistance wire as heater element; With refractory glass fibre as insulating material; The nickel-cadmium resistance wire is wrapped in the insulating barrier, be woven into hemisphere internal heat type heater then, place under the panel.Heater element is communicated with control circuit, and control circuit is through the break-make of electric current or the size of the electric current that control is passed through in the thermostat control heater element, with the temperature that keeps hemisphere internal heat type heater in suitable temperature.Though the fail safe of the more open electric furnace of this type electric jacket increases; But the heater element that it adopted still is resistance element; Not only the heat efficiency is lower; And the heater element of electric heating one and panel, housing contacts are close, and especially insulating material is prone to inefficacy and particularly is heated the container liquid spill that breaks and all can causes housing charged under the high temperature, is prone to take place personal injury accident.
Summary of the invention
The object of the invention is exactly the above-mentioned defective that will overcome prior art, and a kind of efficient, safe electromagnetism heating electric jacket is provided.
For achieving the above object, electromagnetism heating electric jacket provided by the invention comprises that the hemisphere on shell, band edge heats courage and control circuit, also comprises heat-insulating shield and coil in the said shell.The hemisphere on said band edge heats courage, is bearing in the top of said shell, and said coil stationary is installed in the outside of said hemisphere heating courage and links to each other with said control circuit electricity, and said heat-insulating shield is fixedly mounted between said hemisphere heating courage and the said coil.
The part of the hemisphere heating courage longitudinal section on said band edge and the longitudinal section of said heat-insulating shield all are " ∏ " type; The two is respectively equipped with circular recess below flat board separately; Said heat-insulating shield is positioned at the below on edge of the hemisphere heating courage on said band edge; The circular recess of said heating courage is sleeved in the circular recess of said heat-insulating shield; Said heating courage is bearing in the top of said shell, and said coil is a solenoid, and the circular cell wall that said coil stationary is sleeved on said heat-insulating shield links to each other outward and with said control circuit electricity.
Electromagnetism heating electric jacket of the present invention; The cross section diameter of the used lead of wherein said coil is 4.5 millimeters; Close by the stranded back outside of the high temperature resistant enamel covered wire of multiply is that 0.5 millimeter glass wire parcel forms around one deck diameter, and the appearance of said coil has resin-sealed layer.
Electromagnetism heating electric jacket of the present invention, wherein said heat-insulating shield is glass mat or asbestos board, its thickness is less than 3 millimeters.
Electromagnetism heating electric jacket of the present invention, wherein said hemisphere heating courage adopts ferrimagnet to process, and is magnetic stainless steel material or cast iron materials.
The advantage and the good effect of electromagnetism heating electric jacket of the present invention are: because heater element is a coil, it produces eddy current heats up the heating courage, and the heating courage is exactly a heater, so thermal inertia is little, and heating courage heating-cooling rapidly behind the switching electricity.Heat-insulating shield adopts glass mat or asbestos board to constitute, its thin thickness, and the gap is littler between heating courage and the coil, so electromagnetic conversion efficient is higher, saves electric energy more, and easy to maintenance, useful life is also long.Simultaneously because the coil integral sealing and and heating nonmetallic heat-insulating shield is arranged between the courage, electric heating is isolated fully, thereby security performance improves greatly, has guaranteed user's personal safety.
To combine embodiment to be elaborated below with reference to accompanying drawing.
Description of drawings
Fig. 1 is that the master of electromagnetism heating electric jacket embodiment of the present invention looks cutaway view;
Embodiment
Specify the embodiment of electromagnetism heating electric jacket of the present invention below in conjunction with accompanying drawing.
With reference to Fig. 1, electromagnetism heating electric jacket provided by the invention comprises that the hemisphere on shell 1, band edge heats courage 4 and control circuit 5, also comprises heat-insulating shield 3 and coil 2 in the said shell 1.The hemisphere heating courage 4 on said band edge; Be bearing in the top of said shell 1; Said coil 2 is fixedly mounted on the outside of said hemisphere heating courage 4 and links to each other with said control circuit 5 electricity, and said heat-insulating shield 3 is fixedly mounted between said hemisphere heating courage 4 and the said coil 2.
The part of hemisphere heating courage 1 longitudinal section on said band edge and the longitudinal section of said heat-insulating shield 3 all are " ∏ " type; The two is respectively equipped with circular recess below flat board separately; Said heat-insulating shield 3 is positioned at the below on edge of the hemisphere heating courage 4 on said band edge; The circular recess of said heating courage 4 is sleeved in the circular recess of said heat-insulating shield 3; Said heating courage 4 is bearing in the top of said shell 1, and said coil 2 is a solenoid, and the circular cell wall that said coil 2 is fixedly set in said heat-insulating shield 3 links to each other outward and with said control circuit electricity.
Electromagnetism heating electric jacket of the present invention; The cross section diameter of wherein said coil 2 used leads is 4.5 millimeters; Close by the stranded back outside of the high temperature resistant enamel covered wire of multiply is that 0.5 millimeter glass wire parcel forms around one deck diameter, and the appearance of coil 2 has resin-sealed layer.Heat-insulating shield 3 is glass mat or asbestos board, and its thickness is less than 3 millimeters.
Electromagnetism heating electric jacket of the present invention, wherein said hemisphere heating courage 4 adopts ferrimagnet to process, and is magnetic stainless steel material or cast iron materials.
