The through hole be arranged in the first lid connects outside gas heater and stable-pressure device.
Described angle [alpha] is 10 °.
Also be included in the isolated part above molten tin bath, this isolated part bottom distance molten tin bath liquid level 10cm.
Arrange auxiliary isolated part in isolated part bottom, this auxiliary isolated part can move up and down relative to isolated part 6.
This auxiliary isolated part bottom surface moves up and down within the scope of distance molten tin bath liquid level 10cm-2cm.
In auxiliary isolated part, pass into shielding gas, auxiliary isolated part bottom surface evenly arranges gas dispersion aperture, the entrance hole of shielding gas from the position being arranged on the non-bottom surface of auxiliary isolated part imports.
This entrance hole is connected with stable-pressure device with gas heater.
Arrange barrier structure in flow control flashboard front end, this barrier structure is rectangular structure, and be 15-20 millimeter with flashboard distance, be highly 1/3 of liquid level, width is 1.2 times of liquid level, and the width in length and runner matches.
Accompanying drawing explanation
Fig. 1 illustrates that the utility model has the glass manufacturing apparatus schematic diagram of the flow control structure of improvement.
Embodiment
The utility model provides a kind of glass manufacturing apparatus with the flow control structure of improvement.This glass manufacturing apparatus comprises: for the runner 1 of glass metal circulation, the chute 2 for glass metal inflow molten tin bath; Be provided with the first lid above runner, chute, be respectively runner first lid 11 and chute first lid 21; Flow control flashboard 4 is arranged between runner first lid 11 and chute first lid 21, and flow control flashboard 4 can move up and down the glass metal flow controlling to flow into chute from runner; With the molten tin bath 5 be positioned at below chute 2; Wherein, runner first lid 11 and have the first gap between chute first lid 21 and flow control flashboard 4, is respectively runner first gap 411 and chute first gap 421; Runner second lid 12 and chute second lid 22 are set respectively above runner first lid 11 and chute first lid 21, and runner second lid 12, between chute second lid 22 and flow control flashboard 4, form the second gap, be respectively runner second gap 412 and chute second gap 422; The width in two the second gaps is arranged respectively to the width being less than two the first gaps; In the first gap, shielding gas is passed into by the through hole H be arranged in the first lid 11,21; the direction (being the direction of through hole H shown in figure) that passes into of shielding gas is angle [alpha] with horizontal plane angle, and shielding gas forms isolated air-flow at the moved downward of the second lid.The through hole be arranged in the first lid connects outside gas heater and stable-pressure device.Described angle [alpha] is about 10 ° such as 12 °.Illustrate only the through hole of side in figure, it should be noted that opposite side also can adopt this structure.
Glass manufacturing apparatus of the present utility model is also included in the isolated part 6 above molten tin bath, and this isolated part bottom distance molten tin bath liquid level 10cm, for isolating runner and molten tin bath.Preferably, arrange auxiliary isolated part 7 in isolated part 6 bottom, this auxiliary isolated part can move up and down relative to isolated part 6.Preferably this auxiliary isolated part bottom surface 71 moves up and down within the scope of distance molten tin bath liquid level 10cm-2cm.More preferably; shielding gas is passed in auxiliary isolated part 7; particularly; auxiliary isolated part 7 bottom surface 71 is arranged gas dispersion aperture is evenly set; the entrance hole (not shown) of shielding gas from the position being arranged on the auxiliary non-bottom surface of isolated part 7 imports, and this entrance hole is preferably connected with stable-pressure device with gas heater.
More preferably, in flow control flashboard 4 front end, (i.e. the glass metal upstream side of flashboard 4) arranges barrier structure 3, barrier structure 3 is rectangular structure, distance flashboard 4 is apart from being 15-20mm, it is highly 1/3 of liquid level, width is 1.2 times of liquid level, and the width in length and runner matches.By this barrier structure, flashboard can be regulated to open highly on the impact of glass metal flow, when preventing flashboard valve lift larger, large viscosity glass liquid pushes through flashboard causes greater impact unfavorable phenomenon to molten tin bath.
By technique scheme of the present utility model, can while control glass metal flow, protection runner environment is not contaminated, and manufactured quality product is good, and cost is effective, effective.
It should be noted that the utility model is not limited to above-mentioned embodiment, but technique means general in this area can be adopted to replace the above-mentioned technique means of the utility model, to realize same effect.Scope of the present utility model is only defined by the following claims.
