Abstract
A mechanical agitation type wool-making tank liquid replenishing device comprises a liquid storage pot, a liquid transport tube, a liquid replenishing pump, a one-way valve, a flow meter and a wool-making tank. The liquid replenishing pump, the one-way valve and the flow meter are arranged between the liquid storage pot and the wool-making tank after being connected in series by the aid of the liquid transport tube; a liquid suction opening of the liquid replenishing pump is communicated with the bottom of the liquid storage pot by the aid of the liquid transport tube; a liquid outlet of the flow meter is led into the wool-making tank by the aid of the liquid transport tube; and an electric agitation rod is arranged in the liquid storage pot. As the electric agitation rod is additionally arranged in the liquid storage pot and is controlled to start agitation 3-5 minutes before suction of the liquid replenishing pump, chemical reagent in the liquid storage pot can be agitated evenly, and then the upper concentration and the lower concentration of the chemical reagent in the liquid storage pot is even. Besides, the concentration of chemical reagent replenished into the wool-making tank each time is ensured to be the same, and wool-making liquid in the wool-making tank is ensured to meet process requirements, so that stability of wool making process is improved and wool-making quality of silicon slices is ensured.
Description
Technical field:
The utility model relates to the etching device in the solar battery sheet production, relates in particular to the liquid supply device on the etching device.
Background technology:
In the production technology of solar cell, the preparation of suede structure is the important step that increases battery sheet absorptivity.Desirable suede structure helps to improve the performance of battery.Because incident light has increased the absorption of light in the repeatedly reflection and the refraction of silicon chip surface, its reflectivity is very low, is mainly reflected in the raising of short circuit current.The preparation of so-called suede structure is to utilize NaOH dilution, ethylenediamine and chemical mordants such as phosphorus benzenediol water, the monoethanolamine aqueous solution that silicon chip surface is carried out matte to handle, handle the back silicon chip surface and form densely covered pyramid shape tetragonal pyramid, the reflection of incident light rate is reduced in 10%.Making herbs into wool is reflected in the texturing slot to be carried out, because silicon chip and Woolen-making liquid have produced chemical reaction, original chemicals in order to make technology stability stronger, need be replenished corresponding chemicals by reaction consumes in the Woolen-making liquid in Woolen-making liquid after certain reaction times.In order to reduce the number of times of fluid infusion manually, the process of convenient fluid infusion, concentrated liquid supply device must be set, this liquid supply device can a large amount of chemical reagent of disposable storage, in the etching device operation process, according to the design of program, at the appointed time use mechanical pump in texturing slot, quantitatively to replenish chemical reagent.
This texturing slot liquid supply device, as shown in Figure 1, it comprises fluid reservoir 1, woven hose 2, fluid infusion pump 3, unidirectional valve 4, flowmeter 5 and texturing slot 6, fluid reservoir 1 passes through woven hose 2 with fluid infusion pump 3, unidirectional valve 4 and flowmeter 5 are together in series with texturing slot 6, the imbibition end of fluid infusion pump 3 links to each other with the bottom of fluid reservoir 1 by woven hose 2, the outlet end of flowmeter 5 feeds in the texturing slot 6 by woven hose 2, manually the chemical reagent for preparing is joined in the fluid reservoir of being made by the PP material 1, then in the process of etching device operation, at set intervals or after reacting certain number of times, open fluid infusion pump 3, extracting a certain amount of chemical reagent solution from the bottom of fluid reservoir 1 is transported to the texturing slot 6 of etching device by woven hose 2, by the capacity of flowmeter 5 demonstration make-up solution, after reaching predetermined magnitude of recruitment, close fluid infusion pump 3.From add the additional chemical reagent solution for preparing to fluid reservoir 1 after, to replenishing in the process of chemical reagent to texturing slot 6, the chemical reagent solution in the fluid reservoir 1 remains static always.Owing to contain number of chemical article and water in the chemical reagent solution, layering can take place after long-time static, thereby the concentration that has caused the chemical reagent solution of fluid reservoir 1 bottom is higher than the concentration at top, make that the chemical reagent solution concentration of replenishing in the different periods is variant, thereby influenced the stability of process for etching.
The utility model content:
In order to remedy the above deficiency that existing texturing slot liquid supply device exists, the purpose of this utility model provides a kind of mechanical agitation type texturing slot liquid supply device.
The technical scheme that the utility model adopted is:
Described mechanical agitation type texturing slot liquid supply device, it comprises fluid reservoir, woven hose, fluid infusion pump, unidirectional valve, flowmeter and texturing slot, fluid infusion pump, unidirectional valve and flowmeter are arranged between fluid reservoir and the texturing slot after being connected by woven hose, the liquid sucting port of fluid infusion pump is interlinked by the bottom of woven hose and fluid reservoir, the liquid outlet of flowmeter feeds in the texturing slot through woven hose, it is characterized in that: be provided with electronic stirring rod in fluid reservoir.
Further, described electronic stirring rod is made up of stirring motor, bracing frame, main shaft and blade, and stirring motor is fixed on the bracing frame, the output shaft direct connection of main shaft and stirring motor, and vanes fixed is on main shaft, and the length of main shaft is corresponding with the degree of depth of fluid reservoir.
Action request of the present utility model is as follows: before fluid infusion 3～5 minutes, electronic stirring rod was in running order, and the fluid infusion pump startup carries out fluid infusion then, and after fluid infusion finished, fluid infusion pump and electronic stirring rod were closed simultaneously.
Owing in fluid reservoir, set up electronic stirring rod, and control it and just started stirring in preceding 3～5 minutes in the suction of fluid infusion pump, so just can the chemical reagent in the fluid reservoir evenly be stirred, make that the chemical reagent levels concentration in the fluid reservoir is even, the concentration of guaranteeing each chemical reagent that replenishes in texturing slot is identical, guarantee that Woolen-making liquid satisfies technological requirement in the texturing slot, thereby improved the stability of process for etching, guaranteed the making herbs into wool quality of silicon chip.
