Abstract
The utility model discloses a glass edge heater, comprising a tin slot. The utility model is characterized in that the heater for heating the glass edge is arranged on the side of the tin slot opening; a heating element stretches into the interior of the tin slot to locally heat the glass edge that floats on the tin liquor in the tin slot, so as to improve the temperature distribution of the glass edge and provide a uniform heating, reducing the plane stress caused by the temperature differences and effectively improving the quality and quantity of glass products.
Description
Technical field
The utility model relates to a kind of glass strip edge heater that the glass edge of molten tin bath internal float on tin liquor carried out local heating that is used for.
Background technology
At present, in float glass, the molten tin bath an electric heating element generally adopts the three-phase globars, under normal production conditions, only use a small amount of electrically heated temperature adjustment, for the molten tin bath that adopts globars, electrical heating element generally is non-homogeneous layout, has many zones that globars is not installed.Because of the type of heating of electrical heating element mainly is by the radiative transfer heating object, non-homogeneous like this decoration form certainly will cause that heating is uneven, the influence of adding other factors is as molten tin bath banding opening etc., therefore, make molten tin bath banding opening part temperature difference phenomenon occur, all caused glass band edge portion temperature lower,, can cause the problem that often runs in the productions such as glass ribbon unfairness, flounce, cutting difficulty, lobe owing to the plane stress that the temperature difference causes than middle part temperature.Because thin glass ribbon rigidity is relatively poor, plane stress is bigger to its influence, has reduced glass quality and output.
The utility model content
The purpose of this utility model is for addressing the above problem, and a kind of temperature difference that can effectively solve glass ribbon width direction is provided, and improves the glass strip edge heater of glass quality and output.
For achieving the above object, technical solution of the present utility model is finished like this.A kind of glass strip edge heater comprises molten tin bath, and wherein it has in the limit of molten tin bath bead portion a well heater that is used for heating glass limit portion is set.So the lower limit portion of glass ribbon temperature is carried out temperature and add thermal compensation,, reduce the plane stress of glass ribbon to greatest extent, improve the quality and the output of glass so that the temperature distribution on the glass ribbon width direction is more even.
In this was novel, described glass strip edge heater had the outer cover of pair of lamina body, fills thermal insulator in this gap; Outer cover inside be provided with pallet and on be arranged with a plurality of heating units.It mainly acts on is the temperature difference problem of eliminating glass band edge position and middle part temperature, makes it glass ribbon and reduce the possibility that produces defective in subsequent production.
The positively effect that the utlity model has is: be provided with the glass strip edge heater because of having adopted in the limit of molten tin bath bead portion, can effectively carry out local heating to the glass band edge of molten tin bath internal float on tin liquor, to play the temperature distribution of improving glass band edge portion, make glass ribbon laterally be heated more even, thereby reduce the effect of glass internal stress.Fundamentally reduce the possibility that various production defectives take place glass, can increase substantially qualification rate, output and the economic benefit of glassy product.
Description of drawings
Fig. 1 is this novel structure and scheme of installation.
Fig. 2 is Fig. 1 heater structure synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing embodiment, to this novel being further described.The accompanying drawing of giving only is to be used for reference and explanation usefulness, is not to be used to limit the utility model scope.
By Fig. 1, glass strip edge heater shown in Figure 2, the limit portion installation that it has at molten tin bath 1 bead is provided with a well heater 2, this well heater 2 is fixed on the supporting tube 3 of middle part, and passing fixedly by this symmetric middle part supporting tube 3, banding 4 is connected with power supply box 6 with movable banding 5.Described middle part supporting tube 3 is used to introduce supply lead and is connected with external power source with the heating unit of well heater 2 respectively.Described well heater 2, it has the outer cover 7 of pair of lamina body, and the thermal insulator 13 that is filled with the pure aluminium silicate mineral wool in the gap with its periphery, top is equipped with in its inside.Be arranged on the pallet 12 of outer cover 7 inside and be arranged with support 11, and be equipped with by stainless steel bar 8 at support 11, and on be with porcelain tube 9; The heating unit that electrical heating wire 10 is formed is twined in the outside of this porcelain tube 9.
Fixedly banding 4 in above-mentioned is placed in the molten tin bath bead; And movable banding 5 is placed on fixedly in the banding 4, and the middle part supporting tube 3 and the movable banding 5 of well heater is nested together, and well heater 2 and movable banding 5 can be extracted convenient for maintaining work at any time together out from molten tin bath like this.
