Abstract
The invention discloses a cooling device for an aluminium foil formed bath solution, comprising a stainless steel groove, and a tube type heat exchanger is arranged in the stainless steel groove and is formed by connecting a plurality of U-shaped cooling tubes in series. The cooling device for an aluminium foil formed bath solution, which is provided by the invention, directly adopts the tube type heat exchanger arranged in the stainless steel groove for cooling so as to improve the cooling effect.
Description
Technical field
The present invention relates to a kind of refrigerating unit, relate in particular to the refrigerating unit that a kind of aluminium foil changes into tank liquor.
Background technology
The manufacture method of anode aluminium foil is as follows: light paper tinsel-etched foil-change into.Wherein, chemical synthesizing method comprises that pre-treatment-multilevel voltage is energized and forms oxide film-destroy repeatedly and repair oxide film at aluminium foil surface.In formation process, multilevel voltage is energized and need be divided 3～6 grades to add to 190V～1000V from 120V voltage, and along with the rising of the voltage of energizing, aluminium foil is scintillation in changing into tank liquor easily, causes the aluminium foil fracture, influences yield rate.For fear of scintillation, must cool off by centering high-pressure trend forming apparatus electrolytic bath.
The cooling of mesohigh formation device electrolytic bath at present generally adopts the stainless steel flat-panel type heat exchanger to reach this purpose, sees also Fig. 1, and plate-type exchanger 2 direct and stainless steel tanks 1 link to each other, and heat exchange efficiency is low, and in addition, this method also has following drawback:
1) all easily foulings of cold and hot medium channel, and the cycle do not grow up about about 7-15 days, the bad cycle of the processing that has is shorter, in case Xian is clearly only pulled down in fouling, clear Xian is bad also can cause secondary pollution;
2) the stainless steel flat-panel type interchanger heat exchange amount Once you begin occurs to drop to the time that can not reach the temperature control requirement shorter; if untimely processing has only disconnected paper tinsel or shutdown, and both of these case is all very serious to the consequence that the production that changes into paper tinsel and quality control cause.Therefore be necessary that the refrigerating unit that existing aluminium foil is changed into tank liquor improves.
Summary of the invention
Technical problem to be solved by this invention provides the refrigerating unit that a kind of aluminium foil changes into tank liquor, improves heat exchange efficiency, avoids contaminate environment.
The present invention solves the problems of the technologies described above the technical scheme that adopts to provide the refrigerating unit that a kind of aluminium foil changes into tank liquor, comprise stainless steel tank, wherein, be placed with tubular heat exchanger in the described stainless steel tank, described tubular heat exchanger is in series by some U type cooling tubes.
Above-mentioned aluminium foil changes into the refrigerating unit of tank liquor, and wherein, described U type cooling tube diameter is 25～45mm, and the series connection number is 3～15.
The present invention contrasts prior art following beneficial effect: aluminium foil provided by the invention changes into the refrigerating unit of tank liquor, directly adopt the tubular heat exchanger that is placed in the stainless steel tank to cool off, replace existing stainless steel flat-panel type heat exchanger, effectively improved cooling performance.

Fig. 1 changes into the refrigerating unit structural representation of tank liquor for existing aluminium foil;
Fig. 2 changes into the refrigerating unit structural representation of tank liquor for aluminium foil of the present invention.
Among the figure:
1 stainless steel tank 2 plate-type exchangers
3 tubular heat exchangers, 4 U type cooling tubes
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Fig. 2 changes into the refrigerating unit structural representation of tank liquor for aluminium foil of the present invention.
See also Fig. 2, the refrigerating unit that aluminium foil provided by the invention changes into tank liquor comprises stainless steel tank 1, wherein, is placed with tubular heat exchanger 3 in the described stainless steel tank 1, and described tubular heat exchanger 3 is in series by some U type cooling tubes 4.
Above-mentioned aluminium foil changes into the refrigerating unit of tank liquor, and wherein, described U type cooling tube diameter is 25～45mm, and the series connection number is 3～15.
Be example with 8 groups of U type cooling tubes below, illustrate that aluminium foil of the present invention changes into the cooling performance of the refrigerating unit of tank liquor:
1, hangs 8 groups of the shell and tube cooling rows that φ 25～45 stainless steel tubes are processed into all around at electrolytic bath, the size that suitably strengthens electrolytic bath guarantees between every group enough intervals are arranged all when cooling row is installed, and does the dead angle that overcome the tank liquor circulation time like this, lowers the crystallization content on cooling row surface, amplifies limited cooling area to greatest extent;
2, rationally adjust the import and export of on-the-spot pump, make liquid in the groove from top to bottom, by behind the forward direction, from left to right the circulation that goes round and begins again, guarantee that like this liquid in the surperficial flowability of all cooling rows, makes cold and hot exchange fully thorough;
3, rationally adjust 8 groups of cooling rows' the condition of opening according to field working conditions, generally arranging the maintenance normal open state near the cooling of thermal source, remaining cooling row adopts the magnetic valve temperature control, do that so interior metastable thermal value of groove and metastable amount of cooling water are cancelled out each other, tank liquor temperature is more stable;
4, above-mentioned cooling system processing power after using certain hour also can descend, but the cycle longly generally can keep three months, can adopt separately clear Xian of each group to recover cooling power after the discovery, can not influence ordinary production.
In sum, aluminium foil provided by the invention changes into the refrigerating unit of tank liquor, directly adopts the tubular heat exchanger 3 that is placed in the stainless steel tank to cool off, and replaces existing stainless steel flat-panel type heat exchanger 2, has effectively improved cooling performance.In addition, tubular heat exchanger 3 adopts some U type cooling tubes 4 to be in series, and is convenient to assembling, unpicks and washes and keep in repair.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
