Description

Technical Field

[0001] The utility model relates to the field of technical equipment related to launders of heat preservation furnaces, in particular to a heat preservation launder used for producing slag microcrystalline glass. Background Art

[0002] In the prior art, when using slag to prepare microcrystalline glass plates, the commonly used method is the casting method, in which the high-temperature liquid flows directly into the top of the mold through the flow channel and is formed by water cooling. The traditional flow channel only has an outer shell and insulation bricks. When the high-temperature liquid passes through the flow channel, there will be a certain amount of heat loss, and the flow channel is usually set below the discharge port and above the mold. The flow channel has a certain drop from the discharge port and the mold. When the high-temperature liquid falls on the discharge port and the mold, it will bring in air. Under the action of water cooling, when forming on the mold, the air brought in enters the interior of the microcrystalline glass plate and is difficult to be discharged, resulting in many pinholes on the surface of the microcrystalline glass plate, affecting the quality of the microcrystalline glass plate. Utility Model Content

[0003] In order to solve the shortcomings and deficiencies of the prior art, an insulation flow trough for producing slag microcrystalline glass is provided. The technical solution has a simple structure and is easy to install and disassemble, and can be widely used in the production of high-temperature drawn microcrystalline glass plates.

[0004] In order to achieve the purpose of the utility model, an insulation flow channel for producing slag microcrystalline glass is provided, which includes an electric furnace, a discharge port is arranged on the electric furnace, and an insulation chute is arranged on the side wall of the electric furnace. The insulation chute is a cavity with an opening at the upper end, and the bottom and side surfaces of the cavity are paved with insulation bricks. An electric heating device is arranged in the insulation chute, and a discharge chute is arranged at the outer end of the insulation chute away from the electric furnace, and a chute is arranged at the discharge chute. A mold is extended from the outer end of the insulation chute, and the upper end surface of the mold is flush with the upper end surface of the chute. A plurality of cooling water channels are arranged side by side inside the mold, and baffles are symmetrically arranged on the upper end surface of the mold.

[0005] As a further improvement of the above solution, a pair of electric heating devices are symmetrically arranged in the cavity, and the discharge port extends to between the upper parts of the pair of electric heating devices.

[0006] As a further improvement of the above solution, the electric heating device is mounted in the cavity through insulation bricks.

[0007] As a further improvement of the above solution, a support block is symmetrically provided on the outer end of the upper end surface of the chute, and the two ends of the support block are respectively abutted against the electric heating device and the baffle near the outer end.

[0008] As a further improvement of the above solution, a forced water cooling device is provided outside the insulation brick.

[0009] As a further improvement of the above solution, the lower end of the insulation chute is connected to the electric furnace through a bracket.

[0010] The beneficial effects of the utility model are:

[0011] Compared with the prior art, the utility model provides a heat preservation flow trough for producing slag microcrystalline glass, in which an electric heating device is arranged inside the heat preservation flow trough, and the high-temperature slag solution is fully utilized as a conductive medium, with low energy consumption. In the process of heating the liquid in the heat preservation flow trough, as the temperature rises, it is conducive to discharge the air brought in from the discharge port; the flow port of the flow trough is arranged flush with the upper surface of the mold, and the high-temperature liquid overflows directly to the top of the mold in the heat preservation flow trough without a drop, which prevents the secondary introduction of air, can reduce pinholes in the microcrystalline glass plate, and improve the quality of the product.
