Abstract
The invention provides a vacuum sealing processing device for a solar glass heat collecting tube. The specific processing steps are as follows: firstly, the solar glass heat collecting tube is placed in a vacuum chamber; then a vacuum pump is used for pumping the vacuum chamber to the vacuum degree required by the solar glass heat collecting tube, and the vacuum degree in the vacuum chamber is the vacuum degree of a vacuum interlayer of the solar glass heat collecting tube because the glass tube is not sealed; a high-frequency induction heater is started to melt a sealing part of the solar glass heat collecting tube, glass is molten when heated to about 900 DEG C in a vacuum state, and the high-frequency induction heater is closed after the sealing part of the solar glass heat collecting tube is molten; and finally, the sealing part of the solar glass heat collecting tube is subjected to cooling solidification, and vacuum sealing of the solar glass heat collecting tube is finished after the cooling solidification is finished. According to the device, the solar glass heat collecting tube is sealed in a vacuum environment with a high frequency induction heating technology, so that the absolute vacuum degree of the interlayer of the solar glass heat collecting tube is guaranteed, and the device can heat and seal large batch of solar glass heat collecting tubes simultaneously each time.
Description
Technical field
The present invention relates to a kind of processing unit, particularly relate to a kind of solar energy glass heat-collecting pipe vacuum sealing process equipment.
Background technology
Domestic present all manufacturer production solar energy heat collection pipes are all adopt following technique: use exhaust station by vacuum state in Glass tubing, then applying a torch sinters Glass tubing bleeding point.But because Glass tubing is sintering sealing in atmospheric environment, leaks in Glass tubing at the gas still having in a flash trace of sintering sealing, thus affect the vacuum tightness of heat collecting glass tube.If the vacuum tightness of solar energy glass thermal-collecting tube is bad, the energy-saving effect of solar water heater directly will be affected.
Summary of the invention
In order to solve traditional Problems existing, the invention provides following technical scheme is:
A kind of solar energy glass heat-collecting pipe vacuum sealing process equipment, it is characterized in that, its concrete technology step is as follows:
1): first solar energy glass thermal-collecting tube is placed in vacuum cavity,
2): the vacuum tightness (because Glass tubing does not seal, so the vacuum tightness in vacuum cavity is exactly the vacuum tightness of solar energy glass heat-collecting pipe vacuum interlayer) of solar energy glass thermal-collecting tube needs will be extracted in vacuum cavity with vacuum pump afterwards,
3): the closure part (glass is heated to about 900 DEG C under vacuum conditions and will melts) of opening high frequency induction heater fusing solar energy glass thermal-collecting tube,
4): after solar energy glass thermal-collecting tube sealing by fusing, close high frequency induction heater, cooling curing carried out to solar energy glass thermal-collecting tube sealing part,
5): after cooling curing completes, the sealing of solar energy glass heat-collecting pipe vacuum can complete.
Further, solar energy glass thermal-collecting tube and high frequency induction heater is provided with in described vacuum cavity.
Further, described solar energy glass thermal-collecting tube sealing part is provided with high frequency induction heater.
The beneficial effect that the present invention brings is:
1: solar energy glass heat-collecting pipe vacuum sealing process equipment of the present invention puts under vacuum conditions by glass heat collection tube, high-frequency induction heating technology is used to seal Glass tubing, thus ensure the vacuum tightness of solar energy glass thermal-collecting tube, improve the energy-saving effect of solar water heater.
2: solar energy glass heat-collecting pipe vacuum sealing process equipment of the present invention can be disposable in enormous quantities
Glass heat collection tube add hot-seal, promoting the use of of this equipment simultaneously, can to the domestic sun
Glass heat collection tube manufacturer can bring a technological revolution, improve production capacity, save artificial, minimizing
Energy consumption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure is:
1-vacuum cavity, 2-solar energy glass thermal-collecting tube, 3-high frequency induction heater.
Embodiment
Below to being elaborated preferred embodiment of the present invention by reference to the accompanying drawings, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
As shown in Figure 1, a kind of solar energy glass heat-collecting pipe vacuum sealing process equipment, its concrete technology step is as follows: be first placed in vacuum cavity 1 by solar energy glass thermal-collecting tube 2, vacuum tightness that solar energy glass thermal-collecting tube 2 needs will be extracted in vacuum cavity 1 (because Glass tubing does not seal afterwards with vacuum pump, so the vacuum tightness in vacuum cavity is exactly the vacuum tightness of solar energy glass heat-collecting pipe vacuum interlayer), open the closure part (glass is heated to about 900 DEG C under vacuum conditions and will melts) that high frequency induction heater 3 melts solar energy glass thermal-collecting tube 2 again, again after solar energy glass thermal-collecting tube 2 sealing by fusing, close high frequency induction heater 3, finally cooling curing is carried out to solar energy glass thermal-collecting tube 2 sealing part, after cooling curing completes, solar energy glass thermal-collecting tube 2 vacuum seal can complete, in described vacuum cavity, 1 is provided with solar energy glass thermal-collecting tube 2 and high frequency induction heater 3, described solar energy glass thermal-collecting tube 2 sealing part is provided with high frequency induction heater 3.
In sum, solar energy glass heat-collecting pipe vacuum sealing process equipment of the present invention puts under vacuum conditions by glass heat collection tube, high-frequency induction heating technology is used to seal Glass tubing, thus ensureing the Absolute truth reciprocal of duty cycle of solar energy glass thermal-collecting tube interlayer, this equipment disposablely can add hot-seal to large batch of glass heat collection tube simultaneously.
The above; be only one of the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
