Technical field
The present invention relates to once cooling automatic temperature control system of a kind of oxidation tank liquor.
Background technology
During aluminium section bar plant surface treatment, all will have oxidation treatment process, the oxide film that forms one deck>=10 μ m at aluminium shape surface (is AL
2o
3) to form corrosion-resistant protective layer by this tunic, in oxidation trough, carry out in electrolytic oxidation treating processes, aluminium is placed in 15%-18% sulphuric acid soln, then to the logical 10000-15000A of aluminium, the direct current of 18V carries out oxide treatment, during processing, produce amount of heat, if and form high-quality oxide film, tank liquor temperature should be controlled at 20 ± 2 ℃, therefore will force cooling to oxidation tank liquor, the current conventional secondary type of cooling, will be water-cooled to 17 ± 2 ℃ with cooling unit and water cooling tower, then with this water, pass through the cooling oxidation tank liquor of plate heat exchanger, realize oxidation trough liquid temp and be controlled at 20 ± 2 ℃, to meet processing requirement, this type of cooling is necessary in annual May-October during heat, but annual April in November to the coming year mercury dropped, now without ice maker, directly with cooling tower cold water, just can satisfy the demand, with the direct cold water of water cooling tower, can save a large amount of electric energy, bring a large amount of benefits, but due to daytime in winter the temperature difference very large, how to guarantee water cooling temperature to be controlled within the scope of 17 ± 2 ℃, be 20 ℃ of left and right of indirect control flume liquid temp, this is the key issue that a needs solves.
Summary of the invention
The object of the invention is to shortcoming and deficiency for prior art, once cooling automatic temperature control system of a kind of oxidation tank liquor is provided.
The present invention is achieved by the following technical solutions: a kind of oxidation tank liquor is cooling automatic temperature control system once, comprise oxidation trough, interchanger, pond, plc automatic control device, water cooling tower, described oxidation trough is provided with tank liquor output tube and liquid returning tube, described interchanger one end is provided with tank liquor import, tank liquor outlet, the other end is provided with entrance of cooling water and cooling water outlet, the tank liquor output tube of described oxidation trough is provided with tank liquor recycle pump and is connected with the import of interchanger tank liquor, outlet is connected liquid returning tube with interchanger tank liquor, the entrance of cooling water of described interchanger is connected by water inlet pipe with the water outlet of basin bottom, water inlet pipe is provided with cooling water circulating pump, the cooling water outlet of described interchanger is connected by rising pipe with the suitable for reading and water cooling tower in pond, rising pipe is provided with electrically operated valve, top, pond is provided with water cooling tower, the water cooling tower cooling blower that is provided with suitable for reading, surrounding is densely covered ostium excurrens evenly, described plc automatic control device connects PT100p waterproof hot resistance by hot resistance compensation wire, by wire, connect cooling blower and electrically operated valve, described PT100p waterproof hot resistance is placed in pond.
