Abstract
The utility model relates to a violently insert formula high temperature heating ware, it includes heater, fire -resistant sleeve pipe and flange, the left side at the flange is fixed to fire -resistant sleeve pipe, the heater winding is on fire -resistant sleeve pipe, and the heater has two extraction electrode, and this extraction electrode causes the flange right side through the flange, be equipped with insulating washer between flange and the extraction electrode. Heater winding is on fire -resistant sleeve pipe in this heater, and when consequently transversely inserting this heater in the heat treatment furnace, fire -resistant sleeve pipe plays certain supporting role to the heater to the problem of heater because of the gravity deformation has been avoided as far as possible.
Description
Technical field
The utility model relates to heater context, specifically refers to a kind of transverse-plug type high temperature heater (HTH).
Background technology
Transverse-plug type high temperature heater (HTH) refers to that single-ended cantilever mounted formula is without supplemental support, and serviceability temperature can reach the high temperature heater (HTH) of more than 950 DEG C; Existing transverse-plug type high temperature heater (HTH) mainly contains single (or cluster type) tubular heater and bareing (or band overcoat) electric heating radiant tube.
Single (or cluster type) tubular heater take metal tube as shell (comprising stainless steel, copper tube), along central shaft in pipe, there is to distributing auger lectrothermal alloy wire (nickel chromium triangle, ferrochrome) its fill gaps compacting the magnesium oxide sand of good insulation heat conductivility, mouth of pipe two ends silica gel sealing, this metal armouring electric heating element can add hot-air, metal die and various liquid.It is simple that it has structure, the features such as mechanical strength is high, the heat efficiency is high, safe and reliable, simple installation, long service life.
Radiation heating tube is that electrical heating elements is enclosed in heating power in protective sleeve, by sleeve pipe indirectly heat radiation to furnace lining and processed workpiece.The electrothermal alloy material that radiation heating tube uses has higher resistivity, and electric heating conversion ratio is high.Because radiant tube is placed in sleeve pipe, diabatic process is different from general open type electric heating element, and its heat shielding is large, must control, prevent element overtemperature in temperature-rise period to component temperature.These two kinds of transverse-plug type high temperature heater (HTH)s easily normally can not use because of gravity deformation, thermal deformation or high temperature reason in use procedure is crossed under cantilever is without supplemental support state.
Utility model content
For the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of convenient fixing, not easily produces the transverse-plug type high temperature heater (HTH) of distortion in use procedure.
For achieving the above object, the utility model adopts following technical scheme: a kind of transverse-plug type high temperature heater (HTH), comprises heating wire, refractory sleeve and flange; Described refractory sleeve is fixed on the left side of flange; Described heating wire is wrapped on refractory sleeve, and heating wire has two extraction electrodes, and this extraction electrode causes on the right side of flange by flange; Insulating washer is provided with between described flange and extraction electrode.
As preferably, also comprise thermal insulator, this thermal insulator is arranged between refractory sleeve and flange left surface, and one end of thermal insulator is fixedly connected with refractory sleeve, and the other end is fixedly connected with flange left surface.
As preferably, the right flank of described flange is also fixed with hand handle.
Relative to prior art, the utility model tool has the following advantages:
The transverse-plug type high temperature heater (HTH) that the utility model provides, heating wire is wrapped on refractory sleeve, therefore by laterally inserted for this heater heat-treatment furnace time, refractory sleeve plays certain supporting role to heating wire, thus avoids the problem of heating wire because of gravity deformation as much as possible.This transverse-plug type high temperature heater (HTH) can adapt to by single-ended cantilever mounted very well without the occasion inserting container or interior of articles under supplemental support state and carry out high-temperature heating.
Accompanying drawing explanation
Fig. 1 is the structural representation of transverse-plug type high temperature heater (HTH).
Fig. 2 is that Fig. 1 is from the enlarged drawing viewed from P direction.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In description of the present utility model, it will be appreciated that, term "left", "right", interior ", " outward ", etc. the orientation of instruction or position relationship be based on orientation shown in the drawings or position relationship; be only the utility model and simplified characterization for convenience of description; instead of instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See Fig. 1 and Fig. 2, a kind of transverse-plug type high temperature heater (HTH), comprises heating wire 10, refractory sleeve 20 thermal insulator 40 and flange 30.
Thermal insulator 40 is arranged between refractory sleeve 20 and flange 30 left surface, and one end of thermal insulator 40 is fixedly connected with refractory sleeve 20, and the other end is fixedly connected with flange 30 left surface.Refractory sleeve 20 can adopt corundum material to make.
When using this transverse-plug type high temperature heater (HTH), usually by its laterally inserted electric heat treating furnace, the thickness of thermal insulator 40 is suitable with the wall thickness of electric heat treating furnace, thus can reduce the waste of heating wire 10 evolution of heat as much as possible, improves the efficiency of heating in heating wire 10 pairs of stoves.
Heating wire 10 is wrapped on refractory sleeve 20, and heating wire 10 has two extraction electrodes 11, and this extraction electrode 11 causes on the right side of flange 30 by flange 30; Particularly, the extraction electrode 11 of heating wire 10 first through thermal insulator 40, and then passes flange 30.
Insulating washer 12 is provided with between flange 30 and extraction electrode 11.The setting of insulating washer 12 is mainly in order to security consideration.
When installing transverse-plug type high temperature heater (HTH), conveniently staff is hand-held, can also set firmly a hand 31 on the right flank of flange 30.In order to be arranged on the wall of heat-treatment furnace by this transverse-plug type high temperature heater (HTH) easily, flange 30 is also provided with multiple installing hole 32, the plurality of installing hole 32 is uniform along flange 30 circumference.
The occupation mode of this transverse-plug type high temperature heater (HTH) is as follows: be first arranged on the wall of heat-treatment furnace by flange 30 by transverse-plug type high temperature heater (HTH), wherein heating wire 10, refractory sleeve 20 and thermal insulator 40 are positioned at heat-treatment furnace, the extraction electrode 11 of heating wire 10 is positioned at outside heat-treatment furnace, extraction electrode 11 connects electricity, and namely transverse-plug type high temperature heater (HTH) can be heat-treatment furnace heating.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
