Abstract
The utility model discloses a glass electric melting furnace. A furnace chamber of the utility model is enclosed by refractory and thermal insulation materials, wherein, the upper part of the furnace chamber is provided with a feed port, the lower part of one end of the furnace chamber is provided with a discharge port, both sides of the middle part of the furnace chamber is provided with electrodes, and besides, auxiliary electrodes are arranged near the discharge port. The utility model has the obvious advantages of simple structure, economy, practicability, and reliable control. Therefore, the utility model is especially suitable for lamp holder making industries, etc., and can meet the requirements of the automation production process of the utility model.
Description
The utility model relates to a kind of improvement of electrothermal furnace, especially a kind of improvement of electric smelter of melten glass.
Electric smelter is the common equipment of molten glass.Existing electric smelter furnace chamber surrounds with flame-proof thermal insulation material, and furnace chamber top has charging aperture, and an end bottom has discharging opening, and electrode is equipped with in both sides, furnace chamber middle part.After electrifying electrodes, can produce big electric current, make the frit fusing in the furnace chamber.Cooling is too fast and bond during for fear of the glass discharging of fusion, also is provided with fired heater or radiation electric hot pin near the discharging opening.Yet in use, no matter be fired heater or radiation electric hot pin, all be difficult to realize timely, desirable drop temperature control because thermal inertia is big.As a result, often temperature is too high during the glass discharging, and it is too fast to flow, and is difficult to process operation.Especially make lamp holder etc. and require the automated production occasion that discharging is even, speed is suitable, the electric smelter of existing heating mode is just more difficult to have satisfied technological requirement.
The purpose of this utility model is: at the problem that above-mentioned existing electric smelter in use exists, propose a kind of drop temperature and regulate glass electric furnace sensitive, that glass flow suits in the time of can guaranteeing discharging.
In order to achieve the above object, glass electric furnace furnace chamber of the present utility model surrounds with flame-proof thermal insulation material, and furnace chamber top has charging aperture, and an end bottom has discharging opening, and electrode is equipped with in both sides, furnace chamber middle part.In addition, be provided with auxiliary electrode near the discharging opening.
Owing to control easily by the electric current of glass metal when adopting electrifying electrodes to heat, so drop temperature can in time regulate as required, thereby the glass flow when guaranteeing discharging is suitable.The utlity model has simple in structure, economical and practical, control reliable remarkable advantage, be fit to very much industries such as lamp holder making, can satisfy the technological requirement of its automated production.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the utility model.
It among Fig. 1 a kind of glass electric furnace of making lamp holder, the corundum brick 2 that the not only fire-resistant but also refractory of its furnace chamber 1 usefulness melts glass attack surrounds, appearance is the heat-insulation layer 3 that refractory brick is made, furnace chamber 1 upper back has charging aperture 4, the middle and upper part has venthole 5, the irony electrode 8 by 7 controls of constant current temperature controller is equipped with in both sides, furnace chamber middle part, the front end bottom of furnace chamber 1 has discharging opening 6, be fixed with funnel shaped mud bowl 10 by antiseepage backing plate 9 under this discharging opening, be fixed with converter nose 11 under the mud bowl as auxiliary electrode, another utmost point 12 of auxiliary electrode is fixed in the furnace chamber front upper place, and auxiliary electrode is by 13 controls of constant current temperature controller.The glass electric furnace long service life of present embodiment does not have bubble in the glass, low cost of manufacture, the structure at discharging position have and prevent that glass from oozing out or the effect of adhesion.
Facts have proved that the glass electric furnace of this embodiment is used in lamp holder and makes on the production equipment, and glass metal is flowed out by required speed, be cut into the material section again, splash into counterdie, and under the suppression of patrix, make qualified lamp holder with metalwork.
