Description

Izzosti ii.icKipH-JCCKHo hollow glass-melting stoves with separate basins for cooking, clarified production. Each of these pools is equipped with an independent source of heating in the form of electrodes immersed in the glass melt, passed through the side walls and dko of the basin or through its sssd. The electrodes are made with a convex spherical working end and are powered by a three-phase current.

PROMYI1LeN1 (CH.: 1STOTA.

The connection scheme used by the electrodes II to their electrodes has the disadvantage that it does not allow for an increase in the thermal stress in the cooking basin to increase the penetration rate without increasing the number of electrodes. Speresdst T; The contact of the electrodes with the clarified glass melt does not allow it to be completely cleaned of gas inclusions, since the concomitant electric heating is elec- trode: e processes lead to a continuous formation of gas bubbles in the glass melt.

The spherical surface of the working end is convex.

Irrigation to the deviation of the power from the geometrical axis of two mutually .1 opposite-opposite electrodes, to obtaining electric power lines of different lengths, resulting in an uneven distribution of the density of the current on the electrode surface and the rapid unevenness of its destruction.

The proposed furnace is of the type of electric glass-melting furnaces of direct action, fed by three-phase current. In order to eliminate the above disadvantages, ale; Trodes are made with a concave spherical surface and are located in the walls and bottom of the cooking basin and are displaced relative to each other, forming a tetrahedron of force with electrodes at the corners and at the top.

The detachable basin is made in B1; ds of a narrow channel of variable depths, one side of which is plunged into the glass mass, not used — to produce products, submerged electrodes. Thus, the prol; glass mass was subjected to clarification in the channel and then directed to the working bass.

Sein for the production of products is not in contact with the electrodes and is separated from them by a partition mounted inside the lightening basin of the entire swimming pool around its perimeter.

FIG. 1 shows a longitudinal section of the furnace; in fig. 2-h-1d above; in fig. 3-cross-section through the cooking basin PSP; on f1g. 4 is a cross-section through the lighting basin of the furnace; in fig. 3-electrode.

The furnace consists of three consecutive pools; the cooking /, basin 2 for clarifying the glass melt and the basin 3 for cooling and producing glass hopper; each of them is supplied with a self-source iiaipeiv source; glass melt.

In the cooking 6 acceih: e electrodes are laid along the moaning and bottom of the pool. FIpi; In this case, the electrode in one longitudinal wall, as on this electrode, is displaced relative to the electrode in the nrotnvsiolo / -; step. From the schema, the e.ectdseldol connection is also different. pictured on fng. 2, it can be seen that the resulting electric power lines form tetraedra with wall electrons, uanpiniep L ;, / and, .Bi, at angles to the bottom electrodes. Ci at its top. The tetrahedron is in an upside down position. R1 of the four sides of each tetrahedron for electrothermal cooking was taken only two sides, with the aim of using all the qualitative sides of the three-phase electromagnetic field, such as by alternating the phases L1-Bi Ci and creating two stars with a two noBcnxiiom and tetraedra DEO fire stars whose profile zero is given: 1 opposite directions to each other, which does not contribute to the land of ras.chg.va.

the two sides of the tetrahedron for electrothermal cooking creates conditions for the continued operation of the wall lining of the walls and the bottom without disconnecting them. To this end, the electrodes Ci, Cz, Cz, etc., are somewhat inward. The location on the one side of the pool (denominated by the sign} of the charge, the electrodes are very convenient to exclude the requirements of those - ;; -; 1 is safe.

The pool, 2 for conveying the glass melt, is provided with internal partitions 4 forming a narrow channel 5 for clarifying the glass melt in it.

An electric bath is a glass melting furnace with separate basins for cooking, brightening and making glass, equipped with round air-cooled electrodes, characterized in that, in order to achieve maximum heat stress in the cooking pool, reduce the number of electrodes and reduce the wear of the bottom and walls of the pool, the electrodes are located in the walls of the bottom of the cooking basin offset from each other, forming

tetrahedron of lines of force with electrodes along its tops.

2. The form of making the electrode 1, item 1, and so that, in order to achieve equal CMSpiicro current distribution on the working surface of the electrode, its working end is made with a concave spherical surface.

3. Forma performance of bl.ssseyadl, clarification of glass melt of the furnace according to

Claim 1, characterized in that, in order to isolate the electrodes from the brightened glass mass, inside the pool, along its entire length, the overflows are mounted, forming a channel for the brightened glass mass, on the other side of which electrodes are lowered into the unbroken glass mass.

4. The form of the canal in the pool in accordance with and. 3, from the point that, in order to improve the averaging of the clarified glass mass, its bottom is made in the form of successively two double hull ledges, creating a variable depth in the channel.
