More excellent, described cooling system comprises: be located at the liquid circulation tube of tubing, this tubing of UNICOM and the described secondary groove of described major trough inner bottom part, heat exchanger, control valve and the circulation magnetic pump that is connected in series with this liquid circulation tube is connected between heat exchanger and secondary groove.
More excellent, also being provided with the temperature probe that is connected with a controller in described major trough, described circulation magnetic pump is connected with this controller.
More excellent, also be provided with the first float type level switch that is connected with described controller in described major trough, described secondary groove and the sour machine of automatic confession UNICOM.
More excellent, described major trough wall body is provided with the major trough suction opening and connects outside exhausting system.
More excellent, described secondary cell wall body is provided with secondary groove suction opening and connects outside exhausting system.
More excellent, the fast-discharge valve that is connected with the outside also is equipped with in the bottom of described secondary groove.
The utility model has rectangle overflow and fast row's function, has powerful processing power.The utility model unites two into one the secondary groove that originally is in outside major trough, not only make in the assurance function integrity and simplify the structure, and reduced circulating transmission system between major trough and secondary groove, directly realized that by the overflow port of major trough the liquid between major and minor groove carries.The reinforcement of globality has increased stability and the security of cell body pickling, has improved efficient.The minimizing of parts and mechanism has also realized the saving on the material.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is made detailed explanation, wherein:
Fig. 1 is the transverse sectional view of the utility model preferred embodiment;
Fig. 2 is the longitudinal sectional view of the utility model preferred embodiment.
Embodiment
Fig. 1 and Fig. 2 show the basic structure of the utility model preferred embodiment, and described polysilicon core pickling disjunctor groove comprises major trough 1, secondary groove 6.Major trough 1 is connected in the top in secondary groove 6 chambeies, forms the integrated cell body of major and minor groove.The inwall of the outer wall of major trough 1 and secondary groove 6 leaves the gap, and the overflow port 2(that the top edge of major trough is provided with rectangle also can be arranged to wavy overflow port).Also be linked with between major and minor groove can be cooling the cooling system of liquid in major trough 1.In the present embodiment, cooling system comprises: be located at the liquid circulation tube 8 of tubing 7, this tubing of UNICOM and the secondary groove 6 of major trough 1 inner bottom part, the online heat exchanger 9 that is connected in series with this liquid circulation tube, also have control valve 11 and circulation magnetic pump 10 to be connected between heat exchanger 9 and secondary groove 6.Also be provided with the temperature probe 4 that is connected with a controller (not shown) in major trough 1, circulation magnetic pump 10 is connected with this controller.Also be provided with the first float type level switch 5 that is connected with controller in major trough 1, the sour machine of automatic confession (equipment of the preparating liquid) UNICOM of secondary groove 6 and outside.Also be provided with in secondary groove 6 and be connected with controller: high liquid-level floater formula liquid level switch 12 and low liquid-level floater formula liquid level switch 13 and Level meter 14.Major trough 1 wall body is provided with major trough suction opening 20 and connects outside exhausting system.Secondary groove 6 wall bodies are provided with secondary groove suction opening 21 and connect outside exhausting system.The fast-discharge valve 22 with outside UNICOM also is equipped with in the bottom of secondary groove 6.
Referring to Fig. 1 and Fig. 2, when processing the polysilicon core, the cleaning basket that the polysilicon core is housed is placed in the processing major trough 1 that fills the chemical treatment liquid.Can carry out automatization to whole system when cleaning the polysilicon core controls.As, when major trough 1 inner liquid medicine temperature of reaction when too high, temperature probe 4 is passed to controller with electric signal, controller is received and is sent instruction after signal and pass to circulation magnetic pump 10, circulation magnetic pump 10 begins the liquid in secondary groove 6 is flowed to the processing of lowering the temperature of online heat exchanger 9, then is transported to below in major trough 1 by liquid circulation tube 8 and tubing 7, and the liquid of major trough 1 interior top flows in secondary grooves 6 by overflow port 2, so circulation, thus realize the temperature adjustment of major trough 1 inner liquid medicine.
Referring to Fig. 1, when the liquor strength deficiency of the processing polysilicon core in major trough 1 or liquid liquid level when inadequate, the first float type level switch 5 starts circulation magnetic pump 10 runnings by controller, to be stored in the liquid of secondary groove 6 by in liquid circulating line 8 and tubing 7 suction major troughs 1, so circulation, thus realize the adjustment of major trough 1 inner liquid medicine concentration or amount of liquid medicine.High liquid-level floater formula liquid level switch 12 in secondary groove 6 and low liquid-level floater formula liquid level switch 13 are controlled automatically by controller and are automatically replenished the amount of secondary groove 6 inner liquid medicines for sour machine.Major trough and secondary groove are directly realized acid solution transmission by overflow port, and the rectangle overflow port increased the overflow area of acid solution, more are conducive to the cooling of acid solution.In the process of circulation exhausting system will constantly extract major trough 1 in secondary groove 6 in sour gas.And fast-discharge valve 22 has brought convenience for the replacing of acid solution.
The utility model is simple in structure, has satisfactory stability, security and efficient.Be common in the chemical-treating facility of various polycrystalline silicon materials, can adopt different processing modes for different needs.Each functionality advantage is complementary, and mutually noninterfere is in order to reach best treatment effect.When satisfying client's functional requirement, improved safety performance.
