Abstract

The utility model discloses a heater, which belongs to the heating device field. The heater comprises an insulating fixing frame, a superconducting sheet, a mica sheet and an insulating outer casing inner part used for arranging the above objects, wherein the insulating fixing frame is fixed on the inner bottom surface of the insulating outer casing, the mica sheet is fixed on the insulating fixing frame, the superconducting sheet is spirally winded on the mica sheet, and conducting wires are respectively connected at the upper ends of the mica sheet and the superconducting sheet. Because the heater provided by the embodiment of the utility model adopts the superconducting electroheating elements which can instantly generate heat and instantly ensure the heat to be cooled, the delivered heat can be greatly improved through the air convection, the utilization efficiency of heat can be improved, and because the heat can be instantly cooled, the heat can be effectively emitted, to ensure the heater to be more durable.

Description

Heating element

Technical field

The utility model relates to a kind of heating element, and particularly a kind of excitation type heating element is used for the plastic cement drying.

Background technology

Heating element is widely used in the life production, and in the plastic cement drying, the heating element of use mainly adopts tungsten filament as heater element at present, after the energized, make it heating, utilizing air blast that the hot blast that produces is blown to then needs to reach dry effect on the dry plastic material.But the heat residual volume height of existing heating element, efficient has only about 30%, the easy oxidation of tungsten filament, useful life is not long.

The utility model content

The technical problem that the utility model embodiment will solve provides a kind of heating element of superconduction electrothermal part, can improve the cross-ventilation transfer of heat greatly, improves the heat service efficiency, and more durable.

For solving the problems of the technologies described above, the embodiment of heating element provided by the utility model is achieved through the following technical solutions:

A kind of heating element, insulation fixed mount, superconductive pellet, mica sheet and the insulation crust inside that is used to be provided with above-mentioned object, wherein: the insulation fixed mount is fixed on the inner bottom surface of insulation crust, mica sheet is fixed on the insulation fixed mount, the superconductive pellet shape of threads is wrapped on the mica sheet, and the upper end of mica sheet and superconductive pellet is connected to lead respectively.

Technique scheme has following beneficial effect: the heating element heat that the utility model embodiment provides is owing to adopt superconduction electrothermal part moment generation heat and the moment cooling, can improve the cross-ventilation transfer of heat greatly, improve the heat service efficiency, and because heat can cool off moment, effectively distribute heat makes more durable.

Embodiment

The utility model embodiment provides a kind of heating element that is used for the plastic cement drying, and the system that uses.

Fig. 1 is the heating element master TV structure figure of the utility model embodiment; Fig. 2 is the heating element plan structure figure of the utility model embodiment; Fig. 3 is the application structure schematic diagram of the heating element of the utility model embodiment.

With reference to Fig. 1, Fig. 2 and Fig. 3, this heating element comprises insulation fixed mount, superconductive pellet, mica sheet and the insulation crust inside that is used to be provided with above-mentioned object, wherein: insulation plastic cement fixed mount 11 usefulness PLASTIC SCREWSs 16 are fixed on the inner bottom surface of insulation crust 14, for firm more and better heat radiation, plastic cement fixed mount 11 is criss-cross fixed mount, and insulation crust 14 plays insulation, insulation, anti-heat loss effect.Playing insulation and resistant to elevated temperatures mica sheet 13 is fixed on the plastic cement fixed mount 11, heater element superconductive pellet 12 shape of threads are wrapped on the mica sheet 13, the upper end of mica sheet 13 and superconductive pellet 12 is connected to lead 15 respectively, be connected with system control cabinet 17 by lead 15, be used to transmit electric power and the variations in temperature of accurate control heating element.Be provided with power regulating system in system's control cabinet 17 inside, selecting power automatically, thereby play the effect that reduces power consumption at different material is temperature required.

It is superconductive pellet 12 that the heating element that the utility model embodiment provides adopts excitation type high efficiency heater element, moment produces heat, can cool off moment again, so the heat residual volume seldom on the heating element that the utility model embodiment provides, be less than the heat remnants of traditional tungsten filament greatly as heater element, heat can effectively distribute, and the hot blast that utilizes air blast that heating element is produced is blown on the plastic material that needs heated drying, reaches the effect of heat drying.And,, need not frequently change so heater element is to increase greatly in life-span of superconductive pellet 12 because heat can distribute effectively.

Because in plastic cement heating process, radiation can only be heated by short-range straight line, so plastic cement for pipeline, bucket material, can't finish by radiation and to add heat request, need by carrying hot gas to heat, so the heating of the heating element that the utility model embodiment provides is distributed soon, the efficient height plays the effect of power saving.

More than a kind of heating element that the utility model embodiment is provided be described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, part in specific embodiments and applications all can change, in sum, this description should not be construed as restriction of the present utility model.
