Abstract
The utility model discloses a device capable of improving the surface cleaning quality of cold rolling strip steel. The device includes an alkali washing device, an alkali scrubbing device, an electrolytic device, a water scrubbing device, a water rinsing device and a drying device that are arranged in sequence in the operation direction of strip steel, and is characterized in that a blowing device is arranged between an outlet of a wringing roller of the electrolytic device and an inlet of the water scrubbing device. Through the adoption of the device and the technology capable of improving the surface cleaning quality of cold rolling strip steel, the blowing device and the blowing procedure are additionally arranged between the electrolytic procedure and the water scrubbing procedure, and compressed air is blown to the electrolyzed cold rolling strip steel surface through a jet nozzle, so that the surface cleaning quality of cold rolling strip steel is improved further, the water quality purity degree of a water scrubbing circulation tank and a water rinsing tank are kept for a longer time, the discharging period is prolonged, the desalted water consumption is reduced, and the effects of energy conservation, emission reduction and environmental protection are realized.
Description
Technical field
The utility model relates to a kind of cold rolled strip steel production field, on the continuous cleaning by degreasing technology of cold rolled strip, further improves cold rolled strip surface cleaning quality, improves the steady quality that is coated with (plating) converted products of cold rolled strip.
Background technology
In cold rolled strip coating complete processing; Comprise that the japanning of band steel, strip steel Zn-plating, colored steel coating, silicon steel sheet insulating coating etc. are coated with (plating) layer; Cold rolling mill both domestic and external is handled the cleaning section of line at cold rolled strip; All the adopting process step is: alkaline flushing, alkali are scrubbed, electrolysis, water are scrubbed, water rinse and drying; Just the impurity such as grease, iron powder and dust to cold rolled strip surface carry out clean, pass through drying treatment again after, the various cold-rolled products of final production (containing the various product processed that are coated with or plate).
In the practice process, the defective of above-mentioned process step is: through after the electrolysis step and by the band steel after extracting, the limit portion of its upper and lower surfaces all residual to some extent alkali lye, cause the not high and waste de-salted water of belt steel surface cleaning quality.
The utility model content
In view of this, the technical problem that the utility model will solve is to provide a kind of device that improves cold rolled strip surface cleaning quality, thoroughly cleans the alkali lye and the impurity of belt steel surface.
For solving the problems of the technologies described above; The technical scheme of the utility model is achieved in that a kind of device that improves cold rolled strip surface cleaning quality; Comprise along band steel traffic direction setting gradually alkaline flushing device, alkali brushing device, electrolyzer, water brushing device, water rinse device, drying installation, between the inlet of the outlet of the squeezing roller of said electrolyzer and water brushing device, be provided with blow device.
Further, said blow device comprises the purging beam, purges beam down, between this upper and lower purging beam, is provided with the nozzle of blowing out pressurised air, and this nozzle connects the pressurized air person in charge through purging beam.
The technique effect that the utility model reaches is following: the utility model improves the device and the technology of cold rolled strip surface cleaning quality; Through scrubbing increase blow device and step between the step in electrolysis and water; Use the cold rolled strip surface blowing compressed air of nozzle after electrolysis, compressed-air actuated pressure is 0.4 ~ 0.7MPa.Be enough to the alkali lye and the impurity on cold rolled strip surface are purged totally through nozzle, through the pressing method of squeezing roller, up hill and dale that it is more surperficial alkali lye and impurity thereof purge clean, even if the template of cold rolled strip is not good also unaffected than only.Let it get into follow-up journey operation with cleaner situation; Reach the effect of further raising cold rolled strip surface cleaning quality; Can also keep water to scrub the water quality purity of circulation tank and water rinse jar for more time; Prolong its discharging cycle, thereby save the consumption of de-salted water, reach the environment protecting of energy-saving and emission-reduction.

Fig. 2 is the process flow sheet of the device of raising cold rolled strip surface cleaning quality;
Fig. 3 is the structural representation of this clearly demarcated blow device.
Embodiment
Like Fig. 1-shown in Figure 3; Improve the device of cold rolled strip surface cleaning quality for the utility model is a kind of; Comprise along band steel traffic direction setting gradually alkaline flushing device 1, alkali brushing device 2, electrolyzer 3, water brushing device 4, water rinse device 5, drying installation 6, between the inlet of the outlet of the squeezing roller 7 of electrolyzer 3 and water brushing device 4, be provided with blow device 8.
Blow device 8 comprises purging beam 11, purges beam 12 down, on this, purges beam 11 and purges the nozzle 13 that is provided with blowing out pressurised air between the beam 12 down, and these nozzle 13 connections also are connected with the pressurized air person in charge 15.
The utility model improves the technology of cold rolled strip surface cleaning quality; Comprise that step is following: alkaline flushing, alkali are scrubbed, electrolysis, water are scrubbed, water rinse and drying; Also be provided with purge step between the step through scrubbing at electrolysis and water; Use the cold rolled strip surface blowing compressed air of nozzle 13 after electrolysis, compressed-air actuated pressure is 0.4 ~ 0.7MPa.Be enough to the alkali lye and the impurity on cold rolled strip surface are purged totally through nozzle 13, through the pressing method of squeezing roller 7, up hill and dale that it is more surperficial alkali lye and impurity thereof take out clean, even if the template of cold rolled strip 14 is not good also unaffected than only.Let it get into down-stream with cleaner situation; Reach the effect of further raising cold rolled strip surface cleaning quality; Can also keep water to scrub the water quality purity of circulation tank 9 and water rinse jar 10 for more time, prolong its discharging cycle, thereby save the consumption of de-salted water.
The above is merely the preferred embodiment of the utility model, is not the protection domain that is used to limit the utility model.
Claims (2)
