The utility model discloses simple structure, thermal efficiency height, light in weight, low in cost, long service life, be convenient for maintain, applicable in fixed and frequent dismouting needs.
Description
Technical field
The utility model relates to heater context, is specifically related to a kind of soft Resistant heating apparatus.
Background technology
Current employing Electric heating is carried out the heater that in workpiece stove, heat treatment uses and is comprised two types, that is:
A. frame resistance band heater.
B. waveform, spiral yarn shaped or linear resistance wire or resistive band.
Following shortcoming is there is in above technology in actual application:
(1) in stove, arrange the mode of frame resistance band heater, because its version determines, overall weight is large, and heat loss is high, cost is high, fault rate is high, inconvenience maintenance, uncommon on fixed heat-treatment furnace at present, be mainly used in the dismountable heat-treatment furnace temporarily built, but bulky, be not easy to transport and keeping, maintenance difficult.
(2) on furnace wall, fixedly mount resistance wire or the resistive band of all kinds of version, relatively be applicable to fixed heat-treatment furnace, when dismountable heat-treatment furnace for building temporarily, because of needs repeated disassembled and assembled, wiring and insulation measures complexity, the adjustment of body of heater overall power is dumb, and well damage, be not therefore suitable for the occasion needing frequent dismounting to use.
Utility model content
For solving the problem, the utility model provides a kind of soft Resistant heating apparatus, and structure is simple, the thermal efficiency is high, lightweight, cheap, long service life, be convenient to safeguard, be applicable to fixed and frequent dismounting needs.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of soft Resistant heating apparatus, comprise insulating porcelain piece, connecting bolt, lower connecting plate, heater strip, upper junction plate and insulator, described insulating porcelain piece is arranged between lower connecting plate and upper junction plate by bolt, described heater strip walks around insulating porcelain piece one by one by wavy line mode, the in-out end insulator of heater strip is located, insulator is with being bolted on upper junction plate, and heater strip in-out end is connected with stove external power.
As preferably, described upper junction plate is provided with installing hole, is suspended on the position needed in stove by bolt or metal hanger.After energising, heater strip heating, provides heat energy in stove.
As preferably, described insulating porcelain piece is the annular with circular arc inner groovy on the face of cylinder, for ensureing the reliable location of heater strip, causes short circuit to prevent job-hopping.
As preferably, described upper junction plate two ends are designed with grooved fastener with holes, in order to connecting insulator.
The utility model has following beneficial effect:
1) thermal efficiency is high.The heater strip that this structure adopts multifibres to be wound around is as heating element heater, its cross sectional shape is circular, problem that the heat wave overcome in original frame heater and waveform resistive band heating arrangement between adjacent heating tape disturbs and heat energy transmission is obstructed, farthest heat energy can be passed out rapidly, good heat dissipation effect.In addition, because this structure own wt is very light, effectively reduce the heat energy that self temperature rise consumes, this feature is particularly evident for the energy consumption reduction effect of large power, electrically heating furnace.
2) structure is simple, failure rate is low, long service life.This structure is only made up of 6 parts, and wherein the overwhelming majority is general part, manufacture simple, lightweight, in addition heater element surface heat load intensity is low, therefore avoid be short-circuited under applied at elevated temperature state, heating element heater fracture, the situation such as insulating porcelain piece damage occur.
3) use flexibly, applied range.Owing to have employed the mode by waveform coiling between upper lower connecting plate, compared with the frame heater of soft resistance heater and equal-wattage or waveform resistive band block, its appearance and size is compacter, therefore heater quantity unit furnace wall area can arranged can increase, and this greatly facilitates user and adjusts heating power and arrangement as required.The connection that quick plug can realize heater and power supply is installed at heater strip exit, the installation simultaneously adopting hook or bolt can realize heater is fixed, avoiding waveform resistive band need adopt porcelain bar to insert the method for furnace wall fixed resistance band, avoid the destruction to heat-insulation layer, also improve use flexibility simultaneously.This feature of soft heater makes it be specially adapted to need the provisional electric-heating heat treatment stove of the job site of frequent dismounting to use, and is the technology innovation structure of frame resistance band heater.

Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, the utility model embodiment provides a kind of soft Resistant heating apparatus, comprise insulating porcelain piece 1, connecting bolt 2, lower connecting plate 3, heater strip 4, upper junction plate 5 and insulator 6, described insulating porcelain piece 1 is arranged between lower connecting plate 3 and upper junction plate 5 by bolt 2, described heater strip 4 walks around insulating porcelain piece 1 one by one by wavy line mode, the in-out end insulator 6 of heater strip 4 is located, insulator 6 is fixed on upper junction plate 5 with by bolt 2, and heater strip 4 in-out end is connected with stove external power.
Described upper junction plate 5 is provided with installing hole, is suspended on the position needed in stove by bolt or metal hanger.After energising, heater strip heating, provides heat energy in stove.
Described insulating porcelain piece 1 is the annular with circular arc inner groovy on the face of cylinder, for ensureing the reliable location of heater strip, causes short circuit to prevent job-hopping.
Described upper junction plate 5 two ends are designed with grooved fastener with holes, in order to connecting insulator 6.
Wherein, this concrete design power implemented should be determined according to actual conditions, generally should be integer.The material of key element heater strip and the radical of winding silk are selected to determine according to designed maximum operation (service) temperature, and heater strip length must be determined according to relevant thermal technology's designing requirement calculating.The appearance and size of this structure heater should be determined according to concrete application conditions, by applicable needs, can flexible arrangement adjustment, compact conformation, be convenient to, premised on installation and transportation, adopt small size as far as possible; Lower connecting plate suitably should strengthen design weight, is beneficial to ensure that heater strip is in wide-spread state under applied at elevated temperature environment; Insulating porcelain piece 1 and insulator 6 adopt high alumina material to make; Upper lower connecting plate adopts ordinary carbon steel steel plate to be processed into.Wherein lower connecting plate appearance and size is larger.
