Abstract

The utility model discloses an electric heating structure of a platinum channel, which solves the technical problems of nonuniform heating of the glass melt caused by direct heating to the platinum channel and adopts the technical scheme that the electric heating structure comprises a group of electric heating units sectionally arranged on the platinum channel along the axial direction of the platinum channel and a heat-insulating layer arranged outside the electric heating units; and a uniform temperature layer with uniform thickness and coefficient of heat conductivity between 600 and 800W/m*K is added between any electric heating unit and the platinum channel. The utility model has the benefits that the indirect heating to the platinum channel is realized through the uniform temperature layer added between the platinum channel and the electric heating unit, the chemical ionization to the glass melt by the electric heating unit is avoided at the same time, and the temperature controllability of the glass melt is improved.

Description

A kind of electric heating device of platinum channel
Technical field
The utility model relates to a kind of electric heating device of platinum channel, belongs to crucial technical field in the liquid crystal glass base manufacturing, particularly a kind of electric heating device with platinum channel of the electric buffer action of equal gentleness.
Background technology
In the liquid crystal glass base manufacturing processed, to enter through the glass metal of tank furnace fusing and to carry out clarification and homogenization in the platinum channel, to obtain meeting the high quality glass liquid of moulding requirement.Mainly be temperature and the uniform composition that keeps the glass metal homogeneous in homogenization process, this just needs homogenizing zone heating and heat radiation all to want uniform distribution, and can not cause the influence of composition to glass metal.Because cooling section and feed section belong to the end of passage, need accurately regulate glass metal, be met the requirement of condition of molding, if the inhomogeneous of temperature or composition appearred in this position, or glass occurred and owed a little, substantially the chance that does not remedy has again directly entered molding procedure, causes the defective of goods.Traditional platinum channel cooling section and feed section adopt Electric heating usually, and segmentation is provided with the platinum flange on the platinum channel body, pass to electric current for the platinum system by the platinum flange, realize the heating or the insulation of glass metal by the platinum channel body self-heating cooking.Because platinum directly contacts with glass metal, so the heat transmission speed is very fast, and inhomogeneous, can cause heating inhomogeneous owing to distribution of current, make the glass metal generation temperature difference, will cause glass defect production when the temperature difference is serious; High-quality liquid-crystal display is very high to the requirement of glass substrate quality, so present type of heating can not adapt to the requirement of quality, remains further to be improved.
Summary of the invention
The purpose of this utility model is to guarantee that for solving electric heating device carries out even heating to platinum channel, and avoid since directly electrically heated cause the glass metal uneven technical problem of being heated, designed a kind of electric heating device of platinum channel, by between platinum channel and electric heating unit, setting up hypolimnion, realized indirect heating to platinum channel, simultaneously also avoided the chemi-ionization of electric heating unit, improved the controllability of temperature of glass liquid glass metal.
The utility model for realizing the technical scheme that goal of the invention adopts is, a kind of electric heating device of platinum channel, comprise in the electric heating device that one group is arranged on the electric heating unit on the platinum channel and is arranged on thermal insulation layer outside the electric heating unit along the platinum channel axial segmentation, between any one electric heating unit and platinum channel, set up a layer thickness evenly, the hypolimnion of thermal conductivity between 600~800W/mK.
The beneficial effects of the utility model are, by between platinum channel and electric heating unit, setting up hypolimnion, realized indirect heating to platinum channel, simultaneously the heating element that is compounded to form electric heating unit is carried out independent current circuit control, realization improves the controllability of temperature of glass liquid to along the control of platinum channel axial temperature curve and along the control of temperature distribution all around of platinum pipeline, thereby reduces the fraction defective of glass substrate, save production cost, increase economic efficiency.
Below in conjunction with accompanying drawing the utility model is further specified.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing, the platinum channel of glass metal is carried in 1 representative, and 2 represent hypolimnion, and on behalf of segmentation, 3 be arranged on the electric heating unit on hypolimnion surface, and 4 represent thermal insulation layer.
Embodiment
Referring to Fig. 1, a kind of electric heating device of platinum channel, comprise in the electric heating device that one group is arranged on the electric heating unit 3 on the platinum channel 1 and is arranged on thermal insulation layer 4 outside the electric heating unit along platinum channel 1 axial segmentation, between any one electric heating unit 3 and platinum channel 1, set up a layer thickness evenly, the hypolimnion 2 of thermal conductivity between 600~800W/mK.
The material of above-mentioned hypolimnion 2 is corundum or mullite.
The thickness of above-mentioned hypolimnion 2 is 20~50mm.
Between the above-mentioned hypolimnion 2 is 200~600mm at interval.
Above-mentioned electric heating unit 3 is made up of four heating elements of upper and lower two heating elements or upper and lower, left and right, and the thermal value of each heating element is by independent current circuit control.
The material of above-mentioned heating element is platinum or platinum alloy.
The utility model in the specific implementation, referring to Fig. 1, the principle of work of above electric heating device is: heating element is passed to controlled electric current, the electric heating body heating up, at first with the hypolimnion 2 between heat transferred electricity heat-generating units 3 and the platinum channel 1, hypolimnion 2 makes heat can be transmitted to the internal surface of platinum channel 1 uniformly, realizes heating glass liquid by platinum channel 1 again or glass metal is incubated; Simultaneously, will carry out isolated insulation between heating element and the platinum channel 1, do not made electric current pass through glass metal, avoided the generation of phenomenons such as the ion motion of generation glass metal and electrolysis because this hypolimnion 2 be an electrical insulator; This hypolimnion 2 is distributed in around the platinum logical 1 with homogeneous thickness simultaneously, guaranteed all even heat radiations that glass metal is heated evenly; Form owing to electric heat-generating units 3 segmentation settings and by several heating elements, the thermal value of each heating element is by independent current circuit control, can realize realizing the temperature distribution of hope all around, thereby improve the glasswork quality along the control of platinum channel 1 axial temperature curve with along the platinum pipeline.
