Abstract
The utility model discloses a glass metal defoaming device, which comprises a vacuum generator connected to an exhaust hole of a glass pool through a pipeline, wherein the pipeline between the vacuum generator and the exhaust hole is provided with a vacuum pressure meter and a first needle valve; a pipeline for causing high-pressure air to enter into an air inlet of the vacuum generator is provided with a high-pressure air pressure meter and a second needle valve. According to the vacuum generator provided by the utility model, the required device is simple, and the discharge capacity of bubbles in the high-temperature glass metal can be improved without adjusting structures of a tank furnace and a channel.
Description
Technical field
The utility model belongs to glass metal froth breaking technical field, relates to a kind of glass metal defoaming device.
Background technology
Present TFT-LCD glass production mainly be through the high temp glass liquid cooling but moulding prepare, the good article rate of substrate production is very important.And influence one of good article rate very important reasons be that the bubble in the high temp glass liquid is difficult to eliminate.The scheme that now a lot of manufacturers eliminate the bubble employing mainly is: the temperature that improves glass metal; Let bubble from glass metal, overflow; This just requires very high to the refractory materials of glass metal tank furnace; Thereby the increase production cost, and the needed energy of raising temperature also is the problem that must consider.
The utility model content
The technical problem that the utility model solves is to provide a kind of glass metal defoaming device, promotes the discharging of bubble to have improved the bubble effusion through the change of air pressure, has overcome the existing defective of use heat glass metal exhaust.
The utility model is to realize through following technical scheme:
A kind of glass metal defoaming device comprises the vacuum generator that is connected with the venting hole of aquarium through pipeline, also is provided with the vacuum pressure gauge and first needle-valve on the pipeline between vacuum generator and the venting hole; On the pipeline of high-pressure air entering vacuum generator inlet mouth, also be provided with the high-pressure air pressure table and second needle-valve.
Also be connected with sound damper on the exhaust line of described vacuum generator.
Compared with prior art, the utlity model has following beneficial technical effects:
The vacuum generator that the utility model provides; Thereby the high-pressure air through regulating inlet mouth is regulated the vacuum tightness that produces; And the vacuum tightness that is produced can detect through vacuum pressure gauge; Impel high temp glass liquid because pressure is overflowed through controlled vacuum tightness like this, improve the discharge ability of bubble, avoided the existing defective of use heat glass metal exhaust;
Further, install sound damper additional, can reduce the noise in the exhaust process in the discharge end of vacuum generator.
The vacuum generator that the utility model provides, required equipment is simple, need the structure of tank furnace, passage not adjusted, and can improve the discharge ability of bubble in the high temp glass liquid.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1 is vacuum generator; 2 is vacuum pressure gauge; 3 is the high-pressure air pressure table; 4 is sound damper.
Embodiment
Below in conjunction with accompanying drawing the utility model is done to describe in further detail, said is explanation rather than qualification to the utility model.
Referring to Fig. 1, a kind of glass metal defoaming device comprises the vacuum generator 1 that is connected with the venting hole of aquarium through pipeline, also is provided with the vacuum pressure gauge 2 and first needle-valve on the pipeline between vacuum generator 1 and the venting hole; On the pipeline of high-pressure air entering vacuum generator inlet mouth, also be provided with the high-pressure air pressure table 3 and second needle-valve.
After above-mentioned glass metal defoaming device connected in order; Thereby the high-pressure air through regulating inlet mouth is regulated the vacuum tightness that produces; And the vacuum tightness that is produced can detect through vacuum pressure gauge; Impel high temp glass liquid because pressure is overflowed through controlled vacuum tightness like this, improve the discharge ability of bubble.
And, on the exhaust line of vacuum generator 1, also be connected with sound damper 4 in order to reduce the noise in the exhaust process.
The vacuum generator that the utility model provides, required equipment is simple, need the structure of tank furnace, passage not adjusted, and can improve the discharge ability of bubble in the high temp glass liquid.
