Description

A utility model relates to equipment for producing silicate glass.

Glass melting furnaces are known from the prior art, the disadvantages of which are their low productivity and high energy intensity.

The closest in essence to the proposed device is a gas-fired glass melting furnace (Designing energy-efficient glass melting furnaces (monograph) / V.Ya. Dzyuzer, BC Shvydky; edited by V.Ya. Dzyuzer. - Moscow: Teplotekhnik, 2009. - 340 p. .) comprising a housing lined with refractory made with openings in the walls, a burner with exhaust ventilation installed in the opening of the side wall of the housing, loading pockets are made in the upper and lower walls of the housing mounted parallel to each other, in addition to a threshold is located at the bottom of the casing, and the development opening is made in the side wall of the casing at the level of the furnace bottom.

The prototype device has insufficient performance and high energy consumption.

The problem to which the utility model is directed is to create a high-performance plasma glass melting furnace.

The technical result, which is directed to a useful model -acceleration of the process of obtaining silicate glass while reducing its energy intensity.

To achieve a technical result, a plasma glass melting furnace is proposed, including a housing made with openings in the walls, lined with refractory, a burner device, loading pockets, moreover, on the upper wall of the device case there is an opening in which a burner device is installed, which is a plasma type burner with a powder feeder, in addition, two loading pockets are made in the side walls of the housing opposite each other, under which there are two openings for exhaust gas, also the bottom wall of the housing is provided with two openings for draining the molten silicate glass, provided with shutters.

The claimed plasma glass melting furnace differs from the prototype in that:

- on the upper wall of the housing of the device, an opening is made in which a burner device is installed;

- the burner device is a plasma type burner with a powder feeder;

- two loading pockets are made in the side walls of the housing opposite each other, under which there are two openings for exhaust gas;

- on the bottom wall of the housing there are two openings for draining the melt of silicate glass, equipped with gates.

The feed of the charge into the body of the plasma glass furnace through two loading pockets accelerates the process of accumulation of the source material to obtain silicate glass. The plasma torch installed in the opening of the upper wall of the housing allows you to accelerate the process of melting the mixture to the crystalline phase and the formation of a homogenized melt, and the exhaust gases of the plasma torch are discharged through two openings, which reduces energy consumption compared to the prototype. Continuous drainage of the melt of silicate glass through two openings equipped with closures ensures the continuity and acceleration of the process of obtaining silicate glass. Therefore, the proposed plasma glass melting furnace allows you to speed up the process of obtaining silicate glass while reducing its energy intensity, which contributes to the achievement of the technical result.

From the above list of signs of the claimed plasma glass melting furnace and the achievement of the task it is clearly seen that the claimed technical solution is a new set of features that provide a new technical result, not known at the filing date of the application.

The technical solution of the inventive plasma glass melting furnace meets the criterion of "novelty", as it is unknown from the prior art at the date of application.

The proposed plasma glass melting furnace is industrially applicable, as it can be used in the glass industry.

The proposed device is illustrated in the figure. The device comprises a housing 1 lined with refractory 2, made with openings 3, 4, 5, 6, 7 and loading pockets 8 and 9. A plasma torch 10 with a powder feeder is attached to the upper wall of the housing 1 in the opening 3, the exhaust gases of which are discharged through the openings 6 and 7. Pockets 8 and 9 for loading the charge are made in the side walls of the housing 1 opposite each other. The openings 4 and 5, equipped with shutters 11 and 12, are designed to drain the silicate glass melt. The housing 1 is equipped with two support legs 13 and 14 for fixing on a horizontal surface.

An example of using a plasma glass melting furnace.

In the loading pockets 8 and 9 serves a granular charge.

The plasma torch is ignited 10. The granular charge under the influence of high temperatures of the exhaust gases of the plasma torch 10 melts to form a silicate melt that accumulates in the device body 1 to the level of contact with the plasma torch stream 10, which is maintained at a constant level due to the periodic opening and closing of the shutters 11 and 12 on the openings 4 and 5, through which the silicate melt is gradually drained onto a molding machine (not indicated in the figure) for further development of the finished product. The outgoing plasma-forming gases are discharged from the housing 1 s through the openings 6 and 7.
