Specific embodiment
Following further describes the present invention with reference to the drawings.
As Figure 1-Figure 2, the present invention provides a kind of float glass equipment, including molten tin bath 1 and gear flag 6, molten tin baths 1
It is divided into high-temperature region 01, middle warm area 02, low-temperature space 03, it is characterised in that: obvious alternating temperature of the molten tin bath 1 in each temperature range
Point is mounted with gear flag 6, and to control the convection current of tin liquor, 1 internal layer of molten tin bath is equipped with lining brick layer 2, has wrapped up outside lining brick layer 2 solid
To determine shell 20, wraps up water packet outside the set casing 20, water packet is divided into the first water packet 11, the second water packet 12 and third water packet 13,
The water packet be it is detachable, each water packet can be moved by the wheel of the bottom Shui Bao, save the labour of worker
Intensity, the first water packet 11 are installed on outside the high-temperature region 01 of molten tin bath 1, and the second water packet 12 is installed in molten tin bath 1
Outside warm area 02, the third water packet 13 is installed on outside the low-temperature space 03 of molten tin bath 1, and the internal layer of the water packet is cooling circulating water
Layer 3, outer layer is insulating layer, and the insulating layer is divided into alumina silicate fiber felt insulating layer 4 and heat-resisting steel sheet and plate layer 5, the cooling
Temperature inductor is installed in circulation water layer 3, is connected with external temperature controller 7.
Preferably, the gear flag 6 or graphite keep off ship.
Preferably, the heat-resisting steel sheet and plate layer is with a thickness of 2-4mm thickness.
Preferably, the insulating layer is thicker than the thickness of low-temperature zone in the thickness of high temperature section.
The operation principle of the present invention is that: the alternating temperature point installation gear flag or gear ship in different temperatures section in molten tin bath, to molten tin bath
The flow direction of middle tin liquor has carried out mechanical adjustment, while by water packet corresponding outside different temperatures section to tin in molten tin bath
The temperature of liquid is adjusted, and the tin liquor inside molten tin bath is made to occur certain temperature difference as needed, make tin liquor flow direction and
Speed generates corresponding variation, meanwhile, each water packet is connected to different temperature controllers, can temperature to each water packet into
Row is adjusted respectively, carries out the control of temperature difference in realization molten tin bath, the control of tin liquor flow direction and speed is realized, to meet not
