Description
Technical Field
The utility model relates to a lip brick of a glass kiln, in particular to a component applied to an ultra-high light transmission photovoltaic calendaring glass production device.
Background
In the glass kiln technology, the lip brick is a connecting carrier (detachable) of the tail brick and the tail end of a straight passage of a photovoltaic calendaring glass kiln, and is also a final carrier for outputting glass liquid from the kiln, and the glass liquid in the kiln flows to the tail end of the straight passage and is output to an upper roller way and a lower roller way of a calendaring machine through the lip brick to be rolled and formed into the photovoltaic solar glass.
At present, a conventional lip brick is commonly used for an overflow port of a melting furnace: the three-section spliced planar lip brick has the same height with the central section. In order to achieve the production of photovoltaic glass meeting the quality standards of customers in a continuous and uninterrupted production process, the equipment replacement between the melting furnace and the annealing furnace is called: and (5) changing machines. In each replacing process, the lip bricks are separated from the outer tail bricks at the tail end of the straight passage of the melting furnace, residual glass on the connecting surface of the outer tail bricks is removed during the replacing process, so that new lip bricks are replaced, the outer tail bricks at the tail end of the melting furnace are subjected to thermal expansion and cold contraction along with the change of temperature, a certain degree of brick body deformation is caused, the conventional plane lip bricks are used for connecting the outer tail bricks as final bearing of glass liquid, the two brick body installation levels are not matched, on the basis of the fact that the wider overflow port is the larger the transverse temperature difference of the glass liquid, the overflow port bubbles are increased after each replacing process, bubbles are easily aggregated, the bubbles cannot be quickly discharged, the defect that transparent bubbles and sundry bubbles on the glass plate surface are easily generated due to excessively long bubble discharging time is finally caused, the glass yield meeting quality standards is low, the replacing time is also influenced, and the replacing cost is increased.
Chinese patent publication No. CN104163561a discloses a lip brick, which includes a guide surface, and a first side surface and a second side surface respectively connected to two opposite sides of the guide surface. The flow guiding surface comprises a flow guiding surface which is concave inwards towards the lip brick along the direction from the first side surface and the second side surface to the middle part of the flow guiding surface, and the flow guiding surface is used for contacting with molten glass. According to the lip brick, the diversion surface contacted with the glass liquid is set to be the concave surface, the expansion amount of the lip brick when heated is reserved in advance, and further the force generated by the heated expansion of the lip brick is eliminated, so that the lip brick is not easy to break or crack, and the defects of bubbles, lines, bright lines and the like of a glass finished product are eliminated. The flow guiding surface described in the patent comprises a flow guiding surface which is concave towards the lip brick along the direction from the first side surface and the second side surface to the middle part of the flow guiding surface, the flow guiding surface is used for contacting glass liquid, the flow guiding surface is a curved surface, the curved surface comprises a plurality of cambered surfaces which are connected end to end, and the maximum depth of the concave surface is 40 mm.
(1) Under the condition of the same glass liquid level, the amount of glass liquid at the position with the maximum depth of 40mm is large, so that the heat brought by the glass liquid at the position is increased, the temperature of the position with the maximum depth of 40mm is much higher than that of the two side edges, the transverse temperature difference of the glass liquid at an overflow port is large, the control of the calendaring thickness is not facilitated, the thickness difference of finished glass is large, and the yield and the quality are greatly influenced.
(2) After the middle depth of the lip brick is increased, the glass liquid surface is thickened, so that the discharge of bubbles in the lip brick in the middle is not facilitated, the final result is that the bubble discharge time of the lip brick after changing a machine and changing the brick is long, the defective products are more, the qualified product yield is low, and the yield loss is serious.
(3) In addition, the expansion of the lip brick is that the upper, lower, left and right sides are all expanded, the expansion can not be reduced after the surface of the lip brick is concave, and the lip brick can only be improved in the reinforcing mode of fixing the lip brick.
(4) The lip brick only plays a transition role and is used for bearing the support brick for transferring the molten glass from the outer tail brick of the melting furnace to the calender.
After the maximum depth of the concave surface of the lip brick is 40mm, the lip brick mouth at the position is poor in bottom fluidity due to the increase of the liquid level depth of the glass, and the lip brick mouth is easy to cool glass and devitrify, so that the production of a line and a bright line is increased, and the glass yield is seriously affected.
