technical field

The utility model relates to a glass electric melting furnace, in particular to a vertical glass electric melting furnace.

Background technique

The development of glass electric melting furnaces started relatively late in China. At present, the main types of furnaces in China are all-electric melting furnaces and electric-assisted melting furnaces. Although these kilns have a relatively large daily output and are suitable for mass production, they are not suitable for small-batch production and special-shaped products due to their large investment, long refueling cycle, and slow process adjustment.

Contents of the invention

The technical problem to be solved by the utility model is to provide a vertical glass electric melting furnace to make up for the shortcomings and deficiencies of the prior art, in order to achieve the purpose of satisfying household production, producing high-grade special-shaped glass products and enriching glass varieties.

The technical solution adopted by the utility model to solve the technical problems is to provide a vertical glass electric melting furnace, which is composed of a spiral feeding device, heat insulating bricks, zirconium corundum bricks, feeding ports, discharging ports, electrodes, steel structures and kiln ridges , the thermal insulation brick is fixed inside the steel structure, the zirconium corundum brick is located inside the fixed thermal insulation brick, the feeding port and the discharge port are respectively located in the middle of the upper and lower ends of the furnace body, and the spiral feeding device Fixed on the left side of the upper end of the furnace body, the electrodes are evenly distributed on the furnace body and inserted into the inner cavity of the furnace body, and the kiln sill is fixed in the middle of the furnace inner cavity.

The electrodes are divided into three layers, and the electrodes of each layer are arranged horizontally.

The kiln sill is used to prevent the backflow of the molten glass, promote the convection and homogenization of the molten glass, and improve the quality of the molten glass.

Using vertical melting process, melting, clarification, homogenization and cooling are completed in one pool.

Beneficial effect

1. The vertical glass electric melting furnace has a small footprint, compact components and relatively low cost because there are no liquid flow holes, ascending channels and material channels;

2. Because it is always in the vertical melting state, there is no dead material and residual material, so the glass melting efficiency is high, the quality is good and the material is easy to change;

3. Due to the large aspect ratio, it is easy to form a "cold top" feeding process, and it is also convenient for the automatic feeding machine to work;

4. The structure is simple, the construction volume is small, the installation is fast, the operation is simple, and the management is easy;

5. The scale of the melting furnace can be up to or small, from more than a dozen kilograms per day to several tons of glass per day, and the products can also be diversified. Both fusible and refractory glass have achieved good results.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

Example 1

A vertical glass electric melting furnace, which consists of a screw feeding device 1, insulation bricks 5, zirconium corundum bricks 6, feed port 2, discharge port 8, electrodes 3, steel structure 7 and kiln sill 4, the insulation brick 5 is fixed on the steel Inside the structure 7, the zirconium corundum brick 6 is located inside the fixed insulation brick 5, the feed port 2 and the discharge port 8 are respectively located in the middle of the upper and lower ends of the furnace body 9, and the spiral feeding device 1 is fixed on the left upper end of the furnace body 9 On the side, the electrodes 3 are evenly distributed on the furnace body 9 and inserted into the inner cavity of the furnace body 9 , and the kiln ridge 4 is fixed in the middle of the inner cavity of the furnace body 9 . The electrodes 3 are divided into three layers, and the electrodes of each layer are arranged horizontally. The kiln sill 4 is used to prevent the glass liquid from flowing back, promote the convection and homogenization of the glass liquid, and improve the quality of the glass liquid. Using vertical melting process, melting, clarification, homogenization and cooling are completed in one pool.

Among them, the main function of the steel structure is to fix the kiln and control the brick joint of the furnace body. The furnace is equipped with four layers of horizontal electrodes. After the electrodes are energized, Joule heat is generated to heat the glass. Through the optimal configuration of electrode power at different levels, the "thermal history" required for melting glass is completed.

The specific work is as follows: the glass batch material enters the feeding port 2 through the screw feeding device 1, and the batch material is sprinkled on the glass material surface in the furnace. After the electrode 3 is energized, the heat generated directly heats the glass, thereby completing the pre-melting and high temperature of the glass. In the process of melting, clarification and cooling, the kiln sill 4 can change the flow direction of the molten glass and strengthen the convection of the molten glass, thereby improving the quality of the final product. When the temperature of the molten glass reaches the molding temperature, it is discharged from the discharge port 8 .

The utility model can be mainly used for producing lead glass, opal glass, borosilicate glass and some special glasses.
