Abstract
The utility model provides a source jar liquid level measurement device for solar cell diffusion. The device is characterized in that: the device comprises a liquid level display tube positioned on the side of a source jar, the liquid level display tube is communicated with the source jar, and the bottom of the liquid level display tube is provided with a liquid level sensor, which is connected with an external alarm circuit. The utility model has the advantages that: the device can automatically give the alarm on the low liquid level of a diffusion source, the source jar does not need to be directly operated frequently and manually, and the occurrence of safety accidents is prevented.
Description
Technical field
The utility model relates to a kind of solar cell diffusion source bottle liquid level emasuring device.
Background technology
Diffusing procedure is to make PN junction at silicon chip surface, is the committed step that realizes photovoltaic generation, and what generally adopt in the industry at present is the method for gas-entrained liquid phosphorus source diffusion.Be about to gas and feed the quartzy source bottle that liquid is housed, carry phosphorus source steam after moistening to feed in the diffusion furnace.Just there is very high vapor pressure in the phosphorus source under normal temperature and normal pressure, must be incubated in calibration cell, to guarantee its vapor pressure and technology steady concentration.Medium is generally pure water in the calibration cell, and in a single day phosphorus oxychloride contacts with water, vigorous reaction will take place, and generates toxic gas, has serious harmfulness.In process of production, whether the operator needs the regular amount of going to phosphorus source in the bottle of inspection source sufficient, to guarantee the stability of its vapor pressure and technology.When measure in each inspection source, all need artificially in calibration cell, to mention bottle observation residue source, source amount by hand, and bigger stress is assembled easily in air intake opening and bottle junction, source, and undue force or operation often cause because of carelessness ruptures herein and the phosphorus source takes place leak, and the operator is had serious potential hazard.
Summary of the invention
The purpose of this utility model is to provide a provenance bottle liquid level emasuring device.
In order to achieve the above object, the technical solution of the utility model has provided a kind of solar cell diffusion source bottle liquid level emasuring device, it is characterized in that: comprise the liquid level charactron that is positioned at source bottle side, liquid level charactron communicates with the source bottle, be provided with level sensor in the liquid level charactron bottom, level sensor connects external warning circuit.
The utility model has the advantages that: realize that the low liquid level of diffuse source reports to the police automatically, need not manually to prevent the generation of security incident frequently to source bottle direct control.
Description of drawings
Fig. 1 uses synoptic diagram for a kind of solar cell diffusion that the utility model provides with source bottle liquid level emasuring device.
Embodiment
Embodiment
As shown in Figure 1, a kind of solar cell that provides for the utility model spreads with source bottle liquid level emasuring device, comprise the liquid level charactron 6 that is positioned at source bottle 3 sides, liquid level charactron 6 communicates with source bottle 3, be provided with level sensor 7 in liquid level charactron 6 bottoms, level sensor 7 connects external warning circuit.
During work, calibration cell 1 is full of pure water, and placement source bottle 3 is equipped with phosphorus oxychloride liquid in the stainless steel lining 2 in the source bottle 3.Nitrogen enters source bottle 3 through draft tube 4, is entered diffusion furnace by moistening back by escape pipe 5.Liquid level in the liquid level charactron 6 and the liquid level in the source bottle 3 are consistent, level sensor 7 is installed on the bottom of liquid level display 6, the end of a little higher than draft tube 4, residue source quantity not sufficient in bottle, when liquid level is lower than level sensor 7, external circuit is with alarm, thereby realization monitoring automatically prevents the generation of security incident.
