Abstract

The utility model provides a heat-insulation device for a glass channel stirring barrel. The heat-insulation device comprises heat-insulation bricks located on cover plate bricks, wherein heat-insulation cotton is arranged on the heat-insulation bricks; heat-insulation cotton covers the peripheries of the cover plate bricks, the heat-insulation bricks and the heat-insulation cotton. With the adoption of the technical scheme, in order to enhance the heat-insulation performance of the upper part of a glass channel stirrer, one layer of the heat-insulation bricks is arranged on the cover plate bricks at first and one layer of the heat-insulation cotton is additionally arranged on the heat-insulation bricks; furthermore, one layer of the heat-insulation cotton covers the three heat-insulation layers so as to further enhance the heat-insulation effect; an oxidized aluminum wire belt is wound outside the heat-insulation cotton at the periphery so as to achieve the effect of prolonging the service life of the heat-insulation cotton. With the implementation of the scheme, the heat-insulation performance of the glass channel stirring barrel is enhanced well, the possibility of glass devitrification is reduced effectively, the service life of a stirring rod of the stirring barrel is prolonged and the yield is improved.

Description

Glazing channel agitation vat attemperator

Technical field

The utility model relates to a kind of glass metal passage agitation vat attemperator, specifically a kind of attemperator that prevents that heat is lost from agitation vat top.

Background technology

TFT glass belongs to the alkali-free borosilicate glass, and melting temperature (Tm) is high, and glass metal viscosity is larger, and the stirring action of glass metal passage agitation vat is most important to promoting glass metal homogenizing quality, stirs the quality of section state, directly has influence on the good article rate of product.Conventional agitation vat top bore is larger, and the front arch directly covered on agitation vat top directly contacts with air, and heat loss is very fast, thereby causes agitation vat top glass liquid temp to descend temperature on the low side, and the upper and lower glass metal temperature difference more easily exerts an influence to striped; And the front arch upper and lower temperature difference is larger, the place, gap between front arch endoporus and stirring rod is easy to produce the crystallization thing that condenses of glass metal volatile matter, and the crystallization thing is fallen into glass metal and caused that the platinum crystallization excites, and the temperature difference can reduce the work-ing life of stirring rod greatly simultaneously.So must design a kind of heat-preserving equipment, stop scattering and disappearing of heat, reduce the upper and lower temperature difference of front arch.The design is exactly that a kind of assurance agitation vat top glass liquid temp keeps stablizing, and makes stirring rod and the outside air contact position temperature difference reduce simultaneously, extends the work-ing life of stirring rod, guarantees that temperature of glass liquid is stablized and a kind of attemperator of minimizing crystallization simultaneously.

The utility model content

The purpose of this utility model is to provide a kind of device that agitation vat top is incubated, and by the insulation effect of this device, not only can reduce glass metal passage crystallization odds, also can extend the work-ing life of glass liquid stirring rod simultaneously.

For achieving the above object, the utility model is by the following technical solutions:

A kind of glazing channel agitation vat attemperator, it comprises the insulating brick be positioned at above front arch, and insulating cotton is set above insulating brick, and coats peripheral insulating cotton in the periphery of front arch, insulating brick and insulating cotton.

The insulation ring of making in the useful insulation material of the inner liner of insulating cotton cotton.

The front arch internal orifice dimension is less than the insulating brick internal orifice dimension, and the insulating brick internal orifice dimension is less than the insulating cotton internal diameter, and the gap between insulating cotton and stirring rod is filled by bag temperature circle.

Peripheral insulating cotton is wrapped with the high-temperature resistant aluminium oxide silk ribbon.

Adopt the utility model of technique scheme, in order to increase the heat-insulating property on glass metal passage agitator top, at first increase the one layer of heat preservation brick on front arch top, increase again the one layer of heat preservation cotton on insulating brick top, in addition, also will be in the peripheral insulating cotton of above-mentioned three layers of thermal insulation layer external parcel one deck, thus further strengthen heat insulation effect, and peripheral insulating cotton is tied with the aluminum oxide silk ribbon outward, play the effect that extends the insulating cotton life-span.By the enforcement of this scheme, not only strengthened preferably the heat-insulating property of glass metal passage agitation vat, reduce greatly the probability of devitrification of glass, and extended the work-ing life of agitation vat stirring rod, improved good article rate.

The accompanying drawing explanation

Fig. 1 is agitation vat top schematic diagram before attemperator is installed.

Fig. 2 is the agitation vat top schematic diagram after attemperator is installed.

Embodiment

As shown in Figure 1 and Figure 2, a kind of glazing channel agitation vat attemperator, it comprises the insulating brick 3 be positioned at above front arch 4, insulating cotton 1 is set above insulating brick 3, and coat peripheral insulating cotton 5 in the periphery of front arch 4, insulating brick 3 and insulating cotton 1, peripheral insulating cotton 5 is wrapped with high-temperature resistant aluminium oxide silk ribbon 7.

The insulation ring 2 of making in the useful insulation material of the inner liner of insulating cotton 1 cotton, further be incubated the gap around stirring rod.

Further, front arch 4 internal orifice dimensions are less than insulating brick 3 internal orifice dimensions, and insulating brick 3 internal orifice dimensions are less than insulating cotton 1 internal diameter, and the gap between insulating cotton 1 and stirring rod 6 is filled by bag temperature circle 2.So can play heat insulation effect preferably to agitation vat top, avoid the lost generation that causes crystallization of heat, and stirring rod 6 upper ends and attemperator contactless, avoid the friction generation, extended the work-ing life of stirring rod.

Above-mentioned front arch 4, insulating brick 3 and insulating cotton 1 internal diameter are respectively: 80-120mm, 100-150mm and 90-110mm.
