Abstract
The invention discloses a heating device and particularly relates to an improved electric heating element. The technical scheme adopted by the improved heating element is that the improved heating element comprises a heater, a straight tube-type shell and a thermal insulation segment, wherein the straight tube-type shell is arranged outside the heater and used for sealing and protecting the heater; one end of the shell is a closed end and the other end of the shell is an open end, and the open end is provided with a flange; the heater comprises two electrode lead-out rods extending out of the shell, a thermocouple, a plurality of resistance wires connected in series, and a plurality of ceramic collars evenly distributed in the axial direction of the shell; and the resistance wires are high-resistance electrical heating alloy coiled spirally. The improved heating element has advantages of being reasonable in structure, capable of heating various industrial furnaces, wide in usage range, suitable for being used in high-voltage and large-power environments, low in a use failure rate, long in service life, and beneficial to reduction in production cost of enterprises.
Description
Technical field
The present invention relates to a kind of heater, particularly relate to a kind of electrical heating elements of improvement.
Background technology
Heating element is a kind of heater generally adopted in the industries such as metallurgy, medicine, tobacco, weaving, food.In the prior art, heating element major part adopts the electric energy realization heating of high-quality.Existing electrical heating elements, be all that high-resistance electrothermic alloy silk is connected in series by disk insulation, then combine with high-temperature heat-resistance water pipe precaution, the heat that resistance wire sends, by the conduction of heat resisting pipe, heats.Electrical heating elements in the market, its resistance wire generally adopts the high-resistance electrothermic alloy rod with smooth surface, and the resistance wire of this structure also exists resistance wire surface loading greatly, can only be applicable to low-voltage, lower powered occasion.Be unsuitable for using in high, the high-power occasion of some voltages.So just seriously limit its scope of application, more and more can not meet the user demand of vast manufacturer.Therefore, a kind of new technical scheme should be provided to solve the problem.
Summary of the invention
The object of the invention is: for above-mentioned deficiency, a kind of electrical heating elements of rational in infrastructure, result of use good, the scope of application is wide a kind of improvement is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of heating element of improvement; comprise heater, be arranged on heater outside for closing and protect the straight pipe type shell of heater and being arranged on the soaking zone at heater rear; one end of described shell is blind end; the other end is openend; open end is provided with flange; described heater comprises two electrode lead-out rods stretching out shell, thermocouple, the many resistance wires of serial connection and multiple along enclosure axis to the ceramic collar evenly arranged mutually, and described resistance wire is for being coiled into spiral helicine high-resistance electrothermic alloy.
Further technical scheme, described ceramic collar circumferentially evenly has multiple bayonet socket along it.
Due to the employing of technique scheme, the present invention compared with prior art tool has the following advantages:
The present invention is rational in infrastructure, and can carry out heating to multiple industrial furnace and use, the scope of application is wide, and be more suitable for using under high voltage, powerful environment, operational failure rate is low, long service life, is conducive to the production cost reducing enterprise.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, shell, 2, soaking zone, 3, flange, 4, electrode lead-out rod, 5, thermocouple, 6, ceramic collar, 7, bayonet socket, 8, resistance wire.
Embodiment
As shown in Figure 1; the heating element of a kind of improvement of the present invention; comprise heater, be arranged on heater outside for closing and protect the straight pipe type shell 1 of heater and being arranged on the soaking zone 2 at heater rear; one end of shell 1 is blind end; the other end is openend; open end is provided with flange 3; heater comprises two electrode lead-out rods 4 stretching out shell, thermocouple 5, the many resistance wires 8 of serial connection and multiple ceramic collars 6 axially evenly arranged along shell 1 mutually, and resistance wire 8 is for being coiled into spiral helicine high-resistance electrothermic alloy.Design resistance wire 8 is for being coiled into helical form, the surface area of resistance wire can be increased on the one hand, reduce the load on resistance wire surface, go for high-power industrial furnace, user can carry out the spiral density of adjusting resistance silk as required on the other hand, to be suitable for the industrial furnace of different pressures, to improve its scope of application.
Preferably, for improving the stability of resistance wire 8, ceramic collar circumferentially evenly has multiple bayonet socket along it.The more convenient spiral helicine resistance wire dismounting of such structural design, has very strong practicality.
Claims (2)
1. the heating element improved; comprise heater, be arranged on heater outside for closing and protect the straight pipe type shell of heater and being arranged on the soaking zone at heater rear; one end of described shell is blind end; the other end is openend; open end is provided with flange; it is characterized in that: described heater comprises two electrode lead-out rods stretching out shell, thermocouple, the many resistance wires of serial connection and multiple along enclosure axis to the ceramic collar evenly arranged mutually, and described resistance wire is for being coiled into spiral helicine high-resistance electrothermic alloy.
