Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides an all-electric melting device for the production of borosilicate flat glass as Figures 1-4 shown, including a melting pool 1 and a clarification tank 5;

[0022] The melting pool 1 and the clarification tank 5 are connected in series through a liquid flow hole 9. Heating pipes 2 are arranged on the inner walls of both the melting pool 1 and the clarification tank 5, and a fixing plate 10 is arranged on the left side of the liquid flow hole 9;

[0023] A plurality of partition boards 11 are arranged between the two fixing plates 10, and a fixing piece 14 is arranged at the rear side of the upper ends of the two fixing plates 10. The fixing piece 14 is used to fix the partition boards 11 between the fixing plates 10. A plurality of fixing rods 13 are arranged between the plurality of partition boards 11, and the plurality of fixing rods 13 are used to reinforce the partition boards 11.

[0024] The borosilicate raw materials are heated by the heating pipes 2 in the melting pool 1 to be melted. The melted liquid will flow from the liquid flow hole 9 into the clarification tank 5. At the feeding port on the left side of the liquid flow hole 9, the un-melted borosilicate raw materials in the borosilicate liquid are blocked by the plurality of partition boards 11 between the fixing plates 10, so as to prevent the un-melted borosilicate raw material particles from being wrapped by the liquid and flowing into the clarification tank 5.

[0025] As Figure 3 and Figure 4 shown, heat conducting rods 15 are arranged at the front ends of both fixing plates 10, collars 12 are arranged at the front ends of the two heat conducting rods 15, and the two collars 12 are sleeved and fixed on the outer wall of the heating pipe 2. Heat is transferred to the fixing plates 10 through the heat conducting rods 15. The plurality of partition boards 11, fixing plates 10, fixing pieces 14 and heat conducting rods 15 are all made of copper material, and the outer walls are all polished. The two fixing plates 10 and the heat conducting rods 15 are connected and fixed by welding.

[0026] The collar 12 transfers the heat of the heating tube 2 to the fixed plate 10 through the heat-conducting rod 15. Subsequently, the fixed plate 10 transfers the heat to the partition plate 11 through the fixing piece 14. When the liquid flows through the gaps of the partition plate 11, the heat dissipated by the partition plate 11 can also heat the liquid, and can also heat and melt the un-melted borosilicate particles blocked. The partition plate 11, fixed plate 10, fixing piece 14 and heat-conducting rod 15 made of copper have better heat conduction efficiency and can heat the nearby borosilicate faster.

[0027] As Figure 1 and Figure 2 shown, a plurality of lifting rods 3 are arranged at the upper end of the melting pool 1, a cover plate 4 is fixedly arranged at the upper ends of the plurality of lifting rods 3, and the plurality of lifting rods 3 are used to drive the cover plate 4 to lift at the upper end of the melting pool 1. Two observation ports 16 are opened on the outer wall of the melting pool 1, and the two observation ports 16 are used to observe the internal situation of the melting pool 1.

[0028] When heating and melting the borosilicate raw material, the lifting rod 3 jacks up the cover plate 4, pours the borosilicate raw material into the melting pool 1, and heats the borosilicate raw material through the heating tube 2 in the melting pool 1 to melt it. The internal situation of the melting pool 1 can be checked through the observation port 16.

[0029] As Figure 1 and Figure 2 shown, a horizontal channel 6 is arranged at the right end of the clarification tank 5. The horizontal channel 6 is used for cooling and conveying the borosilicate melt. A plurality of automatic discharging devices 8 are arranged at the lower ends of the clarification tank 5 and the horizontal channel 6. The plurality of automatic discharging devices 8 are made of stainless steel as a whole. A stirring mechanism 7 is arranged at the right end of the horizontal channel 6.

[0030] When the liquid in the clarification tank 5 reaches a certain height, it will flow into the horizontal channel 6, and the liquid is cooled and conveyed through the horizontal channel 6. The liquid in the clarification tank 5 and the horizontal channel 6 can be discharged outward through the automatic discharging device 8, so as to clean the clarification tank 5 and the horizontal channel 6.

[0031] Working principle of the utility model: When heating and melting the borosilicate raw materials, the lifting rod 3 jacks up the cover plate 4, and the borosilicate raw materials are poured into the melting pool 1. The heating tube 2 in the melting pool 1 heats the borosilicate raw materials to melt them. The melted liquid will flow from the flowing liquid hole 9 into the clarification pool 5. At the left feeding port of the flowing liquid hole 9, multiple partition plates 11 between the fixing plates 10 block the un-melted borosilicate raw materials in the borosilicate liquid, so as to prevent the un-melted borosilicate raw material particles from being wrapped by the liquid and flowing into the clarification pool 5. The partition plates 11 are used to isolate and block the un-melted borosilicate raw materials. And a collar 12 is fixedly arranged at the front end of the fixing plate 10 through a heat conduction rod 15. The collar 12 is sleeved on the outer wall of the heating tube 2. The collar 12 transfers the heat of the heating tube 2 to the fixing plate 10 through the heat conduction rod 15. Then the fixing plate 10 transfers the heat to the partition plate 11 through the fixing piece 14. When the liquid flows through the gap of the partition plate 11, the heat dissipated by the partition plate 11 also heats the liquid, and can also heat and melt the blocked un-melted borosilicate particles, ensuring that only the melted borosilicate liquid is sent into the clarification pool 5 and guaranteeing the uniformity of the materials during the forming process.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
