Abstract
The utility model discloses an air heating device which comprises a heater, wherein the heater is connected with an isolation transformer, then power regulation is performed through a power regulator to control the power output of the heater. The air heating device is characterized in that the heater comprises an aluminum oxide ceramic pipe; a spiral electric heating wire is arranged on the inner wall of the aluminum oxide ceramic pipe; and a thermal insulation layer is arranged on the outer wall of the aluminum oxide ceramic pipe. The heating device disclosed by the utility model can be used for conveniently performing local temperature regulation and local thickness control of glass in the manufacturing process of a liquid crystal glass substrate, and also can be applied to a laboratory and the heating occasion for processing small products.
Description
Technical field
The utility model relates to during a kind of liquid-crystalline glasses makes, the device that the sheet glass part is heated.
Background technology
In the liquid-crystalline glasses manufacturing processed; Reach the glass metal of certain temperature through heating; Through forming surfacing, consistency of thickness behind the overflow brick, reaching the sheet glass of certain width, again through having formed our needed surfacing, smooth, the uniform liquid-crystalline glasses of thickness after moulding, the annealing.
But form in the process of glass at glass metal; Sometimes at width the inconsistent phenomenon of sheet thickness can appear; So need a kind of heating unit that the liquid-crystalline glasses part is heated; Existing heating unit volume is too big, and the scene can't be installed or Heating temperature can't reach 1000 ℃ of processing requirement.
Summary of the invention
The purpose of the utility model is to overcome that existing heating installation volume is big, and the shortcoming that Heating temperature is low provides a kind of volume little, easy for installation, and heating efficiency is high, and The operation convenient andmeasured can obtain the heating unit of 1000 ℃ of hot blasts through well heater.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of air heating apparatus; Comprise well heater, this well heater carries out power regulation through power regulating eqiupment after connecting IT, the output of control heater power; It is characterized in that; Said well heater comprises alumina ceramic tube, and the alumina-ceramic inside pipe wall is provided with spiral helicine nichrome wire, and the alumina ceramic tube outer wall is provided with thermal insulation layer.
In the such scheme, described nichrome wire employing heatproof is that the lectrothermal alloy wire more than 1300 ℃ is processed.Described alumina ceramic tube adopts 95 alumina-ceramic to process.
The advantage of the utility model heating unit is, vitrified pipe is an elongated tubular construction, to the heating of vitrified pipe inside, makes vitrified pipe internal temperature fast rise through high temperature resistant nichrome wire; According to temperature requirement, can carry out linear regulation to heater temperature, make liquid crystal glass base in manufacturing processed, make things convenient for the control of local temperature adjustment, glass local thickness.The utility model also can be used for the heating occasion of laboratory and processing small sized product.
Description of drawings
The heater structure figure of Fig. 1 the utility model.
Fig. 2 is the principle schematic of the utility model device.
Among the figure: 1 is nichrome wire; 2 is vitrified pipe; 3 is thermal insulation layer; 4 is IT; 5 is well heater; 6 is air flowmeter; 7 is power regulating eqiupment; 8 for purifying air; 9 are the high temperature air after the heating; 10 is the power regulating eqiupment primary source; 11 is the power regulating eqiupment regulator potentiometer; 12 is the power regulating eqiupment trip switch
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Carrying out well heater with reference to figure 1 makes.Select for use a kind of heating efficiency high, heatproof is that nichrome wire 1 (is the Aludirome silk of 0Cr27AL7mo2 like model) more than 1300 ℃ is as pyrotoxin.Make well heater inwall (vitrified pipe 2) with high temperature resistant about 1800 ℃, corrosion-resistant, sludge proof 95 alumina-ceramic 2.In order to reach the rapid heating purpose, prevent that heat scatters and disappears, at vitrified pipe outer setting thermal insulation layer 3, be incubated with insulating cotton, make vitrified pipe 2 internal temperatures reach 1000 ℃ of desired process value fast.
With reference to figure 2; Nichrome wire in the well heater 51 is connected with IT 4, carries out power regulation, the output of control heater power through power regulating eqiupment 7; This moment is through the adjusting of power regulating eqiupment regulator potentiometer 11; The well heater output rating can progressively increase (according to processing requirement) from 0KW, and the well heater internal temperature begins from 0 ℃ of intensification, and the adjusting through power regulating eqiupment makes the well heater internal temperature reach needed process value.
Purify air 8 from the calorifier inlets feeding, flow out from heater outlet, the high temperature air 9 after the heating is 1000 ℃ of hot blasts that need.
Claims (3)
1. air heating apparatus; Comprise well heater, this well heater carries out power regulation through power regulating eqiupment after connecting IT, the output of control heater power; It is characterized in that; Said well heater comprises alumina ceramic tube, and the alumina-ceramic inside pipe wall is provided with spiral helicine nichrome wire, and the alumina ceramic tube outer wall is provided with thermal insulation layer.
2. air heating apparatus as claimed in claim 1 is characterized in that, described nichrome wire employing heatproof is that the lectrothermal alloy wire more than 1300 ℃ is processed.
