Abstract
The utility model belongs to a leading wire structure used for electrically heating the top cover of a tin bath. The utility model is mainly formed by that leading wire bricks are alone arranged in a hole position which is reserved on the top cover bricks of the tin bath; roasting operation and dewatering are carried out on the leading wire bricks; a hanging element which is connected to the end head of each of resistance wires is arranged on the leading wire bricks; the part of the hanging element, which penetrates through the top cover bricks, is connected with a power supply line; as a result, the electrode leadout element of a conductive body is formed. As a result, the problems of short circuit and poor insulating performance are solved, wherein, the problems are caused by that top cover bricks contain moisture. The utility model has the advantages of easy and convenient installation, convenient maintenance, reliable use performance, and power saving by about 4%.
Description
The utility model belongs to a kind of flow passage device that is used for glass furnace with the molten tin bath passage room, is a kind of float glass furnace runner heating arrangement specifically.Owing in the float glass, glass metal enters molten tin bath through runner, chute under the control of adjusting flashboard, for sealing, be incubated and changing chute conveniently, headwall before the molten tin bath arrival end is equipped with one.For cutting off glass metal stream, safe flashboard together is installed on runner, need before the production safety flashboard is heated to predetermined temperature, so that being mentioned the runner that makes by having uniform temperature, safe flashboard enters molten tin bath, be the ready work of next step operation.
The flow passage structure form of using is to adopt the safe flashboard front and back position electric heating part that is installed in the runner or use the spray gun heat temperature raising at present.Because the front of safe flashboard is over against the cooling end of kiln, for aspirating away in the heat major part portion of being cooled on safety flashboard front glass liquid top, the glass metal of the preceding bottom of safe flashboard plays insulation effect to the safety flashboard simultaneously, bring difficulty to heating, and the heat that is added in safe flashboard back only accounts for a part that always adds heat, its thermic load is not enough to this runner temperature is improved rapidly, it is low to make it the thermal efficiency, power consumption is big, and the heating-up time is long, does not reach temperature required requirement.
The purpose of this utility model provides a kind of inner float glass furnace runner heating arrangement that forms airtight heating clamber, has both reduced heat-energy losses, has improved programming rate again.
The purpose of this utility model is achieved in that the runner arrival end with rectangular horn shape is connected with the kiln cooling end, and before runner top safety flashboard and molten tin bath, between the headwall heater is installed, before regulating flashboard and molten tin bath, use the little cover of integral sealing between the headwall, make safe flashboard form an airtight runner heating clamber to the preceding headwall of molten tin bath.After the disconnected glass metal of guard plate lock, also kiln cooling end space and runner heating clamber to be separated simultaneously, regulate flashboard and suitably lift this moment, starts the heater that is installed in the runner heating clamber and can reach safe flashboard of quick rising and runner temperature.
The utility model has the advantages that:
1, the amount of gathering that adopts the rectangular horn shape and deepen glass metal at the runner arrival end, not only enlarged the thermal capacity of glass metal, also increase the thermal convection current of the glass metal of this place's glass metal and kiln cooling end, had the effect that keeps temperature of glass liquid and keep the emergency lock plate temperature.
2, before safety flashboard and molten tin bath, in the runner heating clamber between the headwall heater is installed, is had the minimizing heat loss, improve the effect of programming rate.
3, the movable banding of whole little seal closure and its underpart has the kiln envelope insulation effect to the molten tin bath inlet, is convenient to install the heater flexible and convenient operation.
The drawing explanation of accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Embodiment below in conjunction with accompanying drawing is further described:
Show the cross-section structure of glass furnace runner by Fig. 1, glass furnace outlet cooling end end is connected with runner (7), the arrival end of runner (7) is the rectangular horn shape, make the degree of depth of the degree of depth after of bottom greater than safety flashboard (1), its purpose is to increase the glass metal heat storage capacity in the preceding runner of safe flashboard (1) (7), improves cooling end to the temperature in the heat radiation maintenance runner (7) of runner (7).Runner (7) port of export top promptly is equipped with heater (5) by regulating flashboard (3) between the molten tin bath inlet.For preventing that thermal current from leaking, the outside of fire end also is added with seal closure (4) sealing, make it to form to the preceding headwall of molten tin bath the runner heating clamber of a sealing by safety flashboard (1), and also observable movable banding (6) is housed and is used to observe glass metal in the runner (7) on the one hand at the downside of close cover (4), also can set up spray gun and other heater on the other hand by movable banding (6), improve the interior temperature of runner (7) with this, for reducing heat energy loss, increase the utilization rate of heat energy, guarantee to be rapidly heated in the runner (7), and heat-insulation layer (2) is installed in the outside of whole runner (7).
It is fast to the utlity model has programming rate, and it is low to consume energy, high insulating effect, the advantages such as flexible and convenient operation.
Claims (3)
1, a kind of float glass furnace runner heating arrangement comprises in the runner
The adjusting flashboard of installing, safe flashboard and heating element heater, it is characterized in that having runner (7) arrival end that is connected kiln is a rectangular horn shape, and is added with heater (5) at the top and the molten tin bath arrival end of runner (7) port of export; The outside of heating part is added with seal closure (4) sealing, makes it safe flashboard forms a sealing to the molten tin bath front end runner heating clamber.
2, by the described a kind of float glass furnace runner heating arrangement of claim 1, it is characterized in that the downside of seal closure (4) also is equipped with observable movable banding (6).
3, by the described a kind of float glass furnace runner heating arrangement of claim 1, it is characterized in that runner (7) is equipped with heat-insulation layer (2) all around.
