Description

Novel source bottle

Technical field

The utility model relates to a kind of novel source bottle, particularly relates to a kind of crystal silicon solar energy battery diffusing procedure source bottle.

Background technology

In the Production Flow Chart of multicrystalline solar cells, the main purpose of diffusion technique carries out phosphorus doping exactly, forms P-N junction.In diffusion technique process, source liquid leaves in the bottle of source, carries gas and passes through and carry in the liquid to diffusion furnace tube of a certain amount of source to carry out technique in the bottle of source.An important quality reference mark of diffusion technique product is exactly square resistance (under referred to as sheet resistance), and sheet resistance with carry the source liquid measure that gas carries and have close contacting, and carry the source liquid measure that gas carries and limit by the source liquid measure in the bottle of source.Because phosphorus oxychloride has hypertoxic characteristic, strict working order must be followed in use and Renewal process, time valve opened by source bottle, necessary first manual unlocking escape pipe, then open inlet pipe; During valve-off, first must close inlet pipe, then close escape pipe.If order is opened anti-, very easily cause quartz source bottle to be carried gas support quick-fried, cause high risks.

Utility model content

The utility model devises a kind of novel source bottle, achieves the control to source bottle liquid level, improves source liquid utilization ratio, changes kind valve mechanism, improves safety in operation.

For achieving the above object, the technical solution adopted in the utility model is:

The utility model discloses a kind of novel source bottle, comprise outer blank and valve two portions form.Described outer blank comprises inlet pipe, escape pipe, thermocouple well, source liquid filling exit (airtight when source bottle uses), bottle Valve joint, liquid outlet, Liquid level pipe, liquid storage district; Described valve comprises valve inlet pipe, valve escape pipe, Valve plug; Described valve controls the opening and closing of escape pipe and inlet pipe simultaneously; Described valve is fixed on bottle Valve joint by fastening cutting ferrule; Described Liquid level pipe can store a small amount of remaining liq in liquid storage district.

Adopt the beneficial effect that produces of technique scheme to be: liquid level remains relatively stable, carry gas and carry source liquid measure and keep stable, ensure the stable of process operating conditions.Controlled the opening and closing of escape pipe and inlet pipe by a valve simultaneously, ensure the correct of opening sequence, avoid the security incident that employee's mishandle causes.

Accompanying drawing explanation

Fig. 1 is the structural representation of this novel source bottle;

Fig. 2 is the structural representation of valve;

Fig. 3 is the vertical view of novel source bottle;

As shown in the figure: 1, inlet pipe 2, escape pipe 3, thermocouple well 4, source liquid filling exit 5, valve inlet pipe 6, valve escape pipe 7, Valve plug 8, valve 9, bottle Valve joint 10, liquid outlet 11, Liquid level pipe 12, liquid storage district 13, outer blank.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1, Figure 2, Figure 3 shows, carry gas in use and enter Liquid level pipe 11 through inlet pipe 1, flow out through escape pipe 2 after carrying certain source.Source liquid in liquid storage district 12 is through liquid outlet 10 influent level control pipe 11, after the liquid level in Liquid level pipe 11 there was not liquid outlet 10, because gas cannot enter liquid storage district 12 again, under pressure difference, in liquid storage district 12, source liquid is not in outflow, after using for some time, liquid level in Liquid level pipe 11 drops to liquid outlet less than 10, gas can enter liquid storage district 12 through liquid outlet 10, in liquid storage district 12, source liquid flows out, after again not having liquid outlet 10, source liquid stops flowing out, control source liquid is reached a more stable liquid level with this, ensure to carry the source amount that gas carries stable.In the bottle use procedure of source, the source liquid in liquid storage district 12 can all use, and the small portion finally only in surplus Liquid level pipe 11 cannot be finished, and relatively original source bottle, substantially increases the utilization ratio of source liquid, decrease waste.

When valve 8 uses, be fixed on bottle Valve joint 9 by fastening cutting ferrule, inlet pipe 1, escape pipe 2 are inserted into corresponding pore in valve 8.When Valve plug 7 moves, above move past valve escape pipe 6 in journey and first open, Valve plug 7 moves on continuing, and valve inlet pipe 5 is opened; When Valve plug 7 moves down, in folding process, valve escape pipe 5 is first closed, and Valve plug 7 continues to move down, and valve escape pipe 6 is closed, the opening sequence ensureing air inlet and give vent to anger.

It should be noted that, above-mentioned is only preferred embodiment of the present utility model, is not used for limiting protection domain of the present utility model, and equivalents done on the basis of above-described embodiment all belongs to protection domain of the present utility model.
