Abstract

The utility model relates to a dry electrical bubbler for a glass tank furnace, belonging to the field of producing bubblers for glass tank furnaces. The utility model is characterized in that the dry electrical bubbler for the glass tank furnace is composed of a heat-resisting steel protective tube which has radial clearance and is arranged in the bubble brick prepared hole and is inserted in the bottom of the tank, a metal ceramic tube which is sheathed in the heat-resisting steel protective tube concentrically and is adhered to the heat-resisting steel protective tube and is slightly higher than the internal wall of the bubble brick, a red copper tube which is sheathed in the metal ceramic tube concentrically and adhered to the metal ceramic tube and is longer than the metal ceramic tube, a bubbler steel frame, an insulated supporting board, a tube joint, a locking ring and a locking nut which are sheathed with the existing exterior of the red copper tube sequentially, an another red copper tube whose one end is connected with an air tap and a hose connected with air source in turn and the other end is inserted in the former red copper tube and a braided electrical wire fixed with the exterior of the heat-resisting steel protective tube. The dry electrical bubbler for the glass tank furnace has bending resistance, heat shock resistance and glass liquid etching resistance and the thermal conductivity and the service life are better than the existing most advanced metal ceramic naked bubbler.

Description

Dry electrical bubbler for glass tank furnace

A kind of glass melting furnace belongs to glass melting furnace with dry type electricity unimpeded bubbler and makes the field with bubbler.

Bubbler is used for glass melting furnace and dissolves, can feed thus and purify air or rare gas element, play stirred glass solution, quicken the effect that it flows and strengthens its heat intensity, so that improve the rate of dissolving of admixtion and the uniformity coefficient of glass metal, reach and improve glass quality and purpose of energy saving.At present, more advanced is the exposed bubbler of sintering metal, its key part bubbling pipe is short slightly and be placed in copper tube outer metal ceramic tube and mechanical type web member and form by copper tube, length, it all is being better than the general alumina tube that uses aspect anti-glass solution burn into working life and the heat-shock resistance, but exists fragility shortcoming big, easy to break equally.

The purpose of this utility model is to provide a kind of armouring dry type electricity unimpeded bubbler that resists folding.

Of the present utility model being characterised in that: it is by boxing out interior and high temperature steel protective tube 2 that end face flushes with the interior wall of bubbling brick 1 via inserting the giving of bubbling brick 1 of leaving radius clearance at the bottom of the pond; be placed in one heart in the former and with the metal ceramic tube 4 of the continuous and end face of high-temperature agglomerant 3 a little more than the interior wall of bubbling brick 1; also be to be placed in one heart in the former and to link to each other and the upper surface flushes with the former but its copper tube 5 is outward stretched out in the lower surface with high-temperature agglomerant 3; sequentially be placed in the bubbler Steel Bracket 6 of the former lower end; insulation support plate 7; tube stub 8; securing ring 9 that otch is downward and set nut 10; insert another root copper tube 5 in last copper tube 5 lower surfaces; be coated at the valve 11 of the former the other end; the flexible pipe 12 that is coated at valve 11 and joins with source of the gas and be clamped in high temperature steel protective tube 2 outer braiding electrical leads 13 with bolt and constitute, its structure is seen Fig. 1.

Use proof: its fold resistance and time limit of service all are better than more advanced sintering metal naked pipe bubbler at present.

In order in conjunction with the embodiments the utility model to be done more detailed description below, existing the employed accompanying drawing number of present specification and title brief introduction in down:

Fig. 1: armouring dry type electricity unimpeded bubbler longitudinal section.

Embodiment:

Ask for an interview Fig. 1.Metal ceramic tube 4 is the good specialty metal vitrified pipes of a kind of heat-shock resistance, and insulation support plate 7 usefulness bakelites are made, and the straight frame 6 of bubbler steel is welded on the tank furnace steelframe admittedly.Tube stub 8 is tightened on the bakelite insulation support plate 7, and set nut is screwed into tube stub 8, but does not compress.

Use proof: its fold resistance, heat-shock resistance, anti-glass metal aggressiveness, thermal conductivity and all be better than the exposed bubbler of at present more advanced sintering metal work-ing life.

Claims
