Technical Field

The invention relates to the technical field of glass kilns, in particular to a channel pool bottom structure of a rolled glass kiln.

Background

In the glass rolling kiln, the glass liquid flows out of the channel and enters the rolling machine for forming, the temperature of the glass liquid in the channel is required to be stably reduced, the temperature is uniformly distributed, the glass liquid flows stably, the formed glass liquid has uniform components and fewer defects, and the formed glass liquid meets the forming requirement. The existing rolling glass kiln mostly adopts a flat bottom structure, and an upright pool wall brick is arranged at the outlet of a channel, so that the structure has poor glass liquid fluidity and uneven transverse temperature distribution, is easy to form low-temperature dead glass, and can form the defects of stripes, bubble bands, thickness difference and the like when being brought into a forming part.

Disclosure of Invention

In order to solve the technical problems, the invention aims to provide a channel pool bottom structure of a glass rolling kiln, which can enable the flow of glass liquid to be smoothly transited, reduce the residence time of the glass liquid, avoid the formation of dead glass and provide the glass liquid with uniform temperature distribution and stable flow for rolling forming.

In order to achieve the purpose, the invention adopts the technical scheme that:

the utility model provides a calendering glass kiln passageway bottom of pool structure, clay brick 1 including the level setting is located 1 upper surfaces of clay brick and is provided with one deck corundum ramming mass 2, 2 tops of corundum ramming mass be provided with alpha beta corundum brick 3, be located and set up the step on the clay brick 1, the step on set up climbing brick one 4 and climbing brick two 5, climbing brick one 4 is located two 5 downside of climbing brick, both laminating settings.

When the thickness of the clay brick 1 is 300-500 mm, two layers are arranged.

When the thickness of the clay brick 1 is less than 300-500 mm, a layer is arranged.

The thickness of the alpha beta corundum brick 3 is 75-100 mm.

The gradient alpha of the first climbing brick 4 and the second climbing brick 5 is 30-40 degrees.

And a tail brick 6 is arranged on the first climbing brick 4 close to the second climbing brick 5, and the tail brick 6 and the second climbing brick 5 are arranged separately.

The material of the first climbing brick 4 close to the second climbing brick 5 is alpha beta corundum.

The invention has the beneficial effects that:

through the bottom of the pool structure that sets up the different materials of multilayer, can improve the bottom of the pool temperature, reduce the horizontal difference in temperature of glass liquid, make the horizontal temperature distribution of glass liquid even, reduce defects such as thickness difference, set up the climbing brick at the exit of the passageway, can make the smooth-going transition of glass liquid, reduce glass liquid dwell time, avoid forming dead glass, reduce the glass liquid backward flow, make glass liquid flow steady, the composition is even, improves the glass liquid quality.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figures 1 and 2, the pool bottom is provided with four layers, clay bricks 1 are selected for the first layer and the second layer to play a supporting role, the thickness is selected to be 300-500 mm, the temperature of the pool bottom is increased, and the transverse temperature difference is reduced. If the thickness is selected to be smaller, the structure can be set to be a layer structure; the third layer is made of corundum ramming material 2, and is sintered at high temperature to form a whole, so that the whole sealing effect is achieved, air leakage is prevented, and the thickness is selected to be 20-50 mm; the fourth layer is made of alpha beta corundum bricks 3, the thermal stability is high, almost no glass phase is contained, and basically no pollution is caused to molten glass, so that the fourth layer is used on a surface layer, and the thickness is selected to be about 75-100 mm.

Step two:

a channel outlet pool bottom structure is arranged.

As shown in figure 1 and figure 2, the step is arranged on the clay brick 1, air leakage is prevented, the first 4 and the second 5 climbing bricks are arranged on the step, the first 4 climbing bricks are made of clay materials, the second 5 climbing bricks are made of alpha beta corundum, the gradient alpha is selected from 30-40 degrees to form a certain gradient, the distance h for raising the glass liquid by the climbing bricks is selected according to the extraction amount, 400-700 mm can be selected, when the extraction amount is large, the large value can be selected, certain flow layer thickness is guaranteed, the glass liquid at the bottom of the pool is prevented from flowing actively, the corrosion of refractory materials is accelerated, and the expansion joint at the bottom of the pool causes bubbles under the plate. The climbing bricks are arranged to enable glass liquid to be smoothly transited, so that the residence time of the glass liquid is reduced, the formation of dead glass is avoided, the backflow of the glass liquid is reduced, the flowing of the glass liquid is stable, the components are uniform, and the quality of the glass liquid is improved. The tail brick 6 is arranged on the first climbing brick 4 close to the second climbing brick 5, and the tail brick 6 and the second climbing brick 5 are separately arranged, so that the processing difficulty can be reduced, and the replacement is convenient.
