Technical field
The present invention relates to solar energy glass field of production, the use of cullet in solar energy glass production is particularly related to
Method.
Background technology
The most key process performance index of solar energy glass is the number of bubbles in light transmittance and glass.Light transmittance is main
Influenceed by the iron-holder of glass and the combustion atmosphere of kiln, iron-holder more high transmission rate is lower, reducing atmosphere can reduce printing opacity
Rate；Number of bubbles is main to be produced in the fusion process of glass production, and fusing difficulty causes increased air bubble, and bubble can cause too much
Glass fried piece and is revealed in tempering when solar cell is laminated.Cullet are also known as clinker, and being must be by one in glass production
The raw material that certainty ratio is added, cullet have certain iron-holder in itself, and with the important function such as fluxing, therefore cullet
The use of control is the key factor that solar energy glass is produced.
Solar energy glass belongs to low iron ultra-clear glasses, and the cullet ratio added in production is greater than traditional glass, and
Fluctuation to iron content in raw clinker is very sensitive.At present, by the addition ratio for the cullet for strictly controlling same batch output
Example, makes the use ratio of cullet reach most preferably.But, the fluctuation of cullet iron-holder can cause fusing to be fluctuated, and especially cause
The fluctuation of atmosphere is melted, the stability of glass quality is reduced.In addition, being introduced separately into a kind of cullet, melting furnaces gas may result in
The change of change and the glass metal convection current of atmosphere, so as to produce the formation of the glass defects such as bubble.
The content of the invention
The present invention proposes the application method of cullet in solar energy glass production, maintains the stability of fusion process, maintains
The stability of glass yields, it is to avoid the glass quality because caused by the fluctuation of cullet iron-holder causes fusing fluctuation is fluctuated.
The technical proposal of the invention is realized in this way：
The application method of cullet in a kind of solar energy glass production, by the storage of the cullet of different batches output point storehouse,
And iron-holder and COD value are chemically examined respectively；According to the cullet of iron-holder and the stable principle control different batches output of COD value
Additional proportion；Remove irony debris present in the cullet of different batches output；The broken glass gone out after irony debris is removed in metering
Glass is simultaneously inputted to glass storehouse.
Preferably, it is steady according to iron-holder and COD value in the production of described solar energy glass in the application method of cullet
Determining principle controls the mode of additional proportion of the cullet of different batches output to be, according to containing for the cullet of different batches output
Iron and COD value determine its scope added, and iron content total amount and COD total values reach the ratio value that production technology is formulated；Wherein,
The stable principles of the COD are that the ratio of ferrous and iron in the cullet according to different batches output is determined.
Preferably, in the production of described solar energy glass in the application method of cullet, according to the stable principle of iron-holder,
Total consumption of the cullet of different batches output makes a living the 25~45% of clinker total amount.
Preferably, in the production of described solar energy glass in the application method of cullet, according to the stable principle of COD value,
Granularity of glass cullet is 15~35mm.
Preferably, in the production of described solar energy glass in the application method of cullet, the broken glass of different batches output
During the storage of glass point storehouse, keep pollution-free in each warehouse.
Preferably, different batches output is removed in the application method of cullet in the production of described solar energy glass
The mode of irony debris present in cullet is to remove the iron magazine being clearly present in the cullet of different batches output
Remove, then mix the cullet of different batches output, finally by the iron tramp in the cullet of mixing by being located at cullet
Electric magnetic iron remover on belt conveyor is removed.
Preferably, in described solar energy glass production in the application method of cullet, the iron-holder is 70~
150ppm。
Preferably, in the production of described solar energy glass in the application method of cullet, the ratio of the ferrous and iron
Scope is 0.05~0.25.
