Description

A kind of novel multi-section heater

Technical field

It the utility model is related to heating device technology area, more particularly to a kind of novel multi-section heater.

Background technology

With the continuous development of scientific technology, heat-bending glass technology is constantly progressive.Heat-bending glass refers to glass being placed on mould Softening temperature is heated on tool, then allows glass to curve it shaping by deadweight or external forces, curved surface glass made of annealing Glass, it is too high or too low for temperature all to damage glass, easily cause brokenly magnetic or slight crack.

Generally glass is cuboid, there is 4 sides and 6 faces.Wherein, the heating of the upper and lower surfaces of glass is relative For be slow, especially the centre of glass is often heated most slow, that is, heating complete after the short leg of glass two Temperature is much higher than the temperature among glass.When the short leg temperature of glass two reaches, medium temperature is too high, causes glass to damage It is bad；When temperature among glass just reaches, when glass is molded, two short legs will not enough split because of temperature.

But heater on the market at present, mostly power is unstable and the life-span is not grown, heating is uneven, heating and radiating Relatively slow, heating power is not up to desired effect, and the product fraction defective of production is high.

In summary, the heater, in practice in the presence of it is inconvenient the problem of, it is therefore necessary to improved.

Utility model content

The purpose of this utility model is to provide a kind of novel multi-section heater, is the more power modes of multisection type, the dress Homogeneous heating is put, high temperature resistant, quick heating, good insulating, thermal effect is high, rapid heat dissipation, and temperature control is accurate.

To achieve the above object, using following technical scheme：

A kind of novel multi-section heater, including an at least heating tube, with through hole by heat conductor；The heating tube is embedding Close in the through hole by heat conductor；The heating tube includes heating body, the not all consistent electric heating of at least three sections of spring-like numbers of turn Silk, electrified wire；Concatenated between the heating wire, and be built in heating body cavity；The electrified wire and a wherein electric heating Silk is electrically connected with.

It is preferred that the heating tube includes five, each heating tube includes three sections of heating wire, the first heating wire, the second electricity Heated filament, the 3rd heating wire；Second heating wire is arranged at centre, and the first heating wire and the 3rd heating wire are arranged at both ends；Institute The number of turn for stating the first heating wire and the 3rd heating wire is identical；The number of turn of second heating wire is more than the first heating wire and the 3rd electricity The number of turn of heated filament.

It is preferred that the space filling insulating powder between the heating body cavity inner wall and heating wire.

It is preferred that the through hole by heat conductor includes five, horizontal arrangement is arranged at the length direction by heat conductor；Institute Heating tube one-to-one corresponding is stated to be entrenched in the through hole by heat conductor.

It is preferred that the electrified wire is electrically connected with through the through hole of heating body one end and the first heating wire, and two Person junction sets graphite, for insulating.

It is preferred that it is described by heat conductor with heating body be stainless steel.

Using such scheme, the beneficial effects of the utility model are：

1) number of turn is more than the both ends number of turn among heating wire, i.e., is heated initial stage to glass, and the temperature of center section is higher than two Short side part, temperature are scattered from centre；Due to heated slow among glass, therefore the device can make heated glass heated equal It is even；

2) heat body and used stainless steel by heat conductor, thermal effect is high, high temperature resistant, quick heating；

3) the space filling insulating powder and electrified wire for heating body cavity inner wall and heating wire are connected with the first heating wire Place is insulated with graphite, good insulating.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Referring to figs. 1 to shown in 4, a kind of novel multi-section heater, including it is an at least heating tube 1, heated with through hole Conductor 2；The heating tube 1 is entrenched in the through hole by heat conductor 2；The heating tube 1 includes heating body 11, at least three sections of bullets The not all consistent heating wire 12 of the spring shape number of turn, electrified wire 13；Concatenated between the heating wire 12, and be built in heating body 11 Cavity；The electrified wire 13 is electrically connected with a wherein heating wire 12.

Wherein, the heating tube 1 includes five, and each heating tube 1 includes three sections of heating wire 12, the first heating wire 121, the Two heating wire 122, the 3rd heating wire 123；Second heating wire 122 is arranged at centre, the first heating wire 121 and the 3rd electric heating Silk 123 is arranged at both ends；First heating wire 121 is identical with the number of turn of the 3rd heating wire 123；Second heating wire 122 The number of turn be more than the number of turn of the first heating wire 121 and the 3rd heating wire 123.

Space filling insulating powder between the heating cavity inner wall of body 11 and heating wire 12.It is described by heat conductor 2 Through hole includes five, and horizontal arrangement is arranged at the length direction by heat conductor 2；The one-to-one corresponding of heating tube 1 is entrenched in heated In the through hole of conductor 2.The electrified wire 13 is electrically connected with through the through hole of heating body 11 one end with the first heating wire 121, And graphite is set in the two junction, for insulating.It is described by heat conductor 2 with heating body 11 be stainless steel.

Utility model works principle：

Electrified wire 13 is electrically connected with power supply, switch board respectively, and after energization, heating wire 12 is heated, and heat is passed through Heating body 11 is passed to by heat conductor 2.Because insulating powder is filled in the space between the heating cavity inner wall of body 11 and heating wire 12 It is good with the junction of 13 and first heating wire of electrified wire 121 setting graphite insulation, the insulating properties of whole device.

Comparatively the heating of the upper and lower surfaces of glass is slow, especially the centre of glass is often heated most Slowly, can be with the heated situation of real time inspection glass by the temp controlled meter on switch board.After heating wire 12 is powered, because of the second heating wire 122 number of turn is higher than the heating wire number of turn at both ends, it is ensured that the centre of glass is consistent with the heating temperature of two short legs, reduces Cracking glasses etc. are bad caused by uneven heating is even.

Preferred embodiment of the present utility model is these are only, is not limited to the utility model, it is all in this practicality All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model Within the scope of shield.
