Description

Cooling device for discharge opening of molten glass platinum channel

Technical Field

The utility model relates to a glass liquid platinum passageway discharge opening cooling device.

Background

In the process of manufacturing a platinum channel of a cover plate glass production line, a discharge opening is often used for discharging molten glass liquid. The principle is that a large current is directly added to the discharging platinum tube, the platinum tube is heated, the temperature of the glass liquid is further increased, the viscosity is further reduced, and the glass liquid is discharged. When the discharging is stopped, the discharging can not be stopped because the flow rate of the glass liquid is high or the viscosity is low.

The technical scheme of the utility model is that: the utility model provides a glass liquid platinum passageway discharge opening cooling device, includes the platinum pipe for circulating glass liquid, overlaps at the platinum pipe periphery and is equipped with the corundum brick, overlaps at the corundum brick periphery and is equipped with the insulating brick, is provided with inlet channel in the upper end of corundum brick and insulating brick, is provided with exhaust passage at corundum brick and insulating brick lower extreme, is provided with the cooling channel who communicates with inlet channel and exhaust passage on the surface that the corundum brick touches with the platinum pipe.

Further, an air inlet pipe is arranged at the air inlet end of the air inlet channel.

Further, a valve for controlling the flow rate of intake air is provided in the intake pipe.

Furthermore, an exhaust pipe is arranged at the air outlet end of the exhaust channel.

Furthermore, an installation groove matched with the platinum pipe is arranged in the center of the corundum brick.

Furthermore, the air outlet end of the air inlet channel is communicated with the mounting groove.

Further, the air inlet end of the exhaust passage is communicated with the mounting groove.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses simple structure, easy and simple to handle, can control the temperature of platinum pipe through control inlet flow and velocity of flow, and then control the velocity of flow of glass liquid in the platinum pipe.

Detailed Description

As shown in fig. 1 to 5, a glass liquid platinum channel discharge opening cooling device comprises a platinum pipe 100 for circulating glass liquid, a corundum brick 200 is sleeved on the periphery of the platinum pipe 100, a heat insulation brick 300 is sleeved on the periphery of the corundum brick 200, an air inlet channel 400 is arranged at the upper ends of the corundum brick 200 and the heat insulation brick 300, an exhaust channel 500 is arranged at the lower ends of the corundum brick 200 and the heat insulation brick 300, and a cooling channel 210 communicated with the air inlet channel 400 and the exhaust channel 500 is arranged on the surface of the corundum brick 200 contacted with the platinum pipe 100. When the material is unloaded, the feed inlet at the upper end of the molten glass platinum pipe 100 enters the platinum pipe 100, the temperature of the platinum pipe 100 is increased due to the high temperature of the molten glass, the corundum brick 200 can resist high temperature and can be used for fixedly supporting the platinum pipe 100, and the insulating brick 300 can insulate heat transferred to the corundum brick 200, reduce heat loss and avoid the viscosity of the molten glass from being increased. When needs stop unloading, let in compressed air in intake passage 400, compressed air gets into cooling channel 210 after passing through intake passage 400, discharge from exhaust passage 500 at last, compressed air can take away the heat on the platinum pipe 100 at the in-process that cooling channel 210 flows, cool off platinum pipe 100, and then make the glass liquid stickness in the platinum pipe 100 uprise, when the viscosity of glass liquid is higher, glass liquid can stop flowing, finally realize stopping unloading.

In the present embodiment, an intake pipe 410 is provided at the intake end of the intake passage 400. The air outlet end of the air inlet pipe 410 is communicated with the air inlet of the air inlet channel 400, and the air inlet end of the air inlet pipe 410 is communicated with the air source of the compressed air.

In the present embodiment, a valve 411 for controlling the flow rate of intake air is provided in the intake pipe 410. The flow and rate of gas passing into the inlet pipe 410 can be controlled by a valve 411.

In this embodiment, an exhaust pipe 510 is disposed at the air outlet end of the exhaust channel 500. The hot air is exhausted through the exhaust duct 510.

In this embodiment, an installation groove 220 matched with the platinum tube 100 is arranged at the center of the corundum brick 200.

In this embodiment, the air outlet end of the air inlet channel 400 is communicated with the mounting groove 220.

In this embodiment, the air inlet end of the exhaust passage is communicated with the mounting groove 220.

Above-mentioned operation flow and software and hardware configuration only do as the preferred embodiment of the utility model discloses a not therefore restrict the patent scope of the utility model, all utilize the utility model discloses the equivalent transform of doing of description and attached drawing content, or directly or indirectly use in relevant technical field, all the same reason is included in the patent protection scope of the utility model.
