SU16828A1 - Installation for separating molten glass stones - Google Patents

Description

Patent No. 14523, issued to the author, describes a pistonless pump for transferring molten glass mass, in which a bottomless vessel glass installed on the bottom of the basin of the smelting furnace, expanded and equipped with a bottom window and a bowl-shaped sink at the upper end, and inserted into some the depth along the axis of the specified vessel tubular air duct, passed through the arch of the furnace and equipped with a refrigerator. The air duct serves to bring compressed air into the glass mass at a certain temperature in order to cause the glass mass to rise in the vessel by means of foaming and to pour it through the drain.

TOGO) so that the overflow into the drain, when the air is forced out, the glass mass can be freed from the stones, in the present invention the bowl-shaped discharge of the pump is shaped like a trough, which provides a spout with stones at the stopper and a number of holes near the glass with the fitted gratings made of flame retardant materials to filter stones that could be in the glass.

On the schematic drawing of the proposed installation is shown in vertical section.

In the molten glass basin, the above described pistonless pump is installed, the bowl-shaped drain of which is shaped like a trough. Near the level of the glass mass, the trough B is supplied with a series of apertures / C into which are inserted from fused alundum, zirconium oxide, a glass-resistant Krupp alloy or the like of resistant Y, U grate materials that filter out the glass melt. To remove the U, U grabs caught by the grates, the trough B is also supplied with a spout C, a stopper D with a stop bolt E passing through the window F in the wall G. The surrounding space of the pump is simultaneously enclosed with a float Q, on which the glass that has passed through the lattices U, U spreads and released from the bubbles. The installation is as follows: at the beginning of the operation, the cleaned air duct L is introduced through the opening R, R of the furnace roof into the cavity LG of the vessel A. When air is pumped into the pipe L with appropriate short pulsing doses, the glass mass is sucked from the bottom of the pool through the hole N and, lifting After being blown large in the cavity M, it is poured into the trough B. Slowly flowed through the openings of the gratings Y, U, the mass is freed from the stones and is quietly again distributed over the glass surface enclosed by the float Q. In such an operation, the glass mass is finally freed from air bubbles and, according to the author, is reduced to a more uniform temperature and state. As the stones accumulate in the trough, the bolt E is removed, the opening F, usually open, is closed by the damper H, and the stopper D heats up and lags behind the spout C. After removing the stopper and the damper, air is pumped into the pump and the pressure is released to the glass through the trough. spout C. To facilitate cleaning, a stirrer-hook is sometimes introduced through the hole P into the trough.

The subject of the patent.

An apparatus for separating stones from molten glass by pumping it into a filtering vessel, characterized by using the pump without pump described in patent no. 14523, attached to the upper edge of the modified trough B, equipped with spout C, closed plug D with a stop bolt Ej and several holes / f, located near the glass level, with built-in gratings made of fused alunlum, zirconium oxide, glass-refractory Kruper or other resistant materials, with the aim of pouring it into the drain e trough during a short pulse doses injected glass mass of air passing through the marked lattice freed of stones and spreading Referring float in a fenced area, resulting in more uniform temperature.
