Description

The roll coater liquid circulating apparatus
Technical field
The utility model relates to the cold rolling technology field, relates in particular to a kind of passivation device that is used for zinc-plated unit post processing section.
Background technology
Roll coater is the visual plant of the zinc-plated unit post processing of cold rolling mill passivation section, roll coater requires to be installed in the lower part of up section of band steel, its process schematic representation such as Fig. 1 on unit, 21 for stablizing roller in the bottom, 22 is the circulatory system of roll coater, and 23 is roll coater, and 24 is Heating air box, 25 are the band steel, and 26 is top roller.The effect of roll coater 23 is to apply corresponding immersion coating on band steel two sides, the band steel is played the effect of anti-corrosion protection.22 of the circulatory systems of roll coater are for belt steel surface provides the chromium-free deactivation solution-treated, the structure of its circulatory system as shown in Figure 2, this circulatory system comprises dosing path, transfusion path, roller flush path.
Among Fig. 2,1a, 1b, 1c, 1d, 1e, 1f are the groove jar, 2a, 2b, 2c, 2d, 2e are pneumatic pair of barrier film constant displacement pump, 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3k, 3m, 3n, 3p, 3q, 3t, 3w are motor-driven valve, 4a, 4b are filter, 5 is the roller of roll coater, 6 catch trays for the stainless steel making.Pneumatic pair of barrier film constant displacement pump got to stoste holding vessel 1b with stoste from original liquid box, and then gets to blending tank 1c.Equally, constant displacement pump is got to blending tank 1c with desalted water from desalted water holding vessel 1a, accurately controls the solution mixed proportion.Operating personnel preset among the blending tank 1c after the solution use amount, measure with flowmeter then.Guarantee that the stoste and the desalted water that add accurately mix on demand.The solution that mixes flows into periodic duty jar 1d, 1e by gravity from blending tank 1c.Then, an air driven pump is got to roll coater catch tray 6 with solution from periodic duty jar 1d, 1e.Get back to periodic duty jar 1d, 1e after getting to the redundant solution overflow of roll coater catch tray 6.
Under situations such as shutdown or switching coating,, need clean with desalted water in order to prevent the residual masking liquid slagging scorification on roller 5 and the catch tray 6.Cleaning fluid is discharged to effluent pit, and the cleaning fluid in the effluent pit is got to waste water processing station with self priming centrifugal pump, perhaps gets to groove tank car otherwise processed.
Though said system can reduce the residual coating slagging scorification on roller and the catch tray, but the circulatory system of this structure in use, 1), the circulatory system is not rinsed often the problem that occurs mainly contains:, residue coating can solidify slagging scorification in the circulatory system, and among two periodic duty jar 1d, the 1e coating is housed for a long time, summer temperature than higher, after perhaps pump moves for a long time, the temperature of pump raises, cause the temperature of coating to raise, coating at high temperature will slagging scorification, and can cause the obstruction of pipeline, causes the holiday of belt steel surface coating; 2), because the coating in the circulatory system is not rinsed totally, after switching coating, originally remaining coating will produce pollution to the coating after switching in system, influence the purity and the cleannes of coating, causes the coating quality problem of being with steel; 3), the flushing liquor after the flushing of pair of rollers and catch tray directly is discharged into effluent pit, a large amount of residue coating in the circulatory system are not recycled, cause the wasting of resources, and caused the pollution of environment, a large amount of waste water has also increased the sewage disposal burden and the difficulty that can be situated between, and causing cost of sewage disposal to improve, the roll coater system is one of source of sewage that the sewage of cold rolling mill is maximum, intractability is maximum; 4), because the plugging fault of roll coater need carry out the band steel of Passivation Treatment and can only postpone production, upset the production schedule.
Now market requires more and more highlyer to product quality, and environmental requirement is also more and more higher, and cost pressure is big simultaneously, so said system and do not meet the needs of current market and production development.
Summary of the invention
The purpose of this utility model provides a kind of roll coater liquid circulating apparatus, can avoid it to condense to the circulation of coating cooling, can carry out circulation flushing and waste liquid is utilized once more the coating tank body.Prevent the coating slagging scorification and cause the obstruction of system, reduce the holiday of roll coater and the strip quality problem that causes, reduce the downtime of roll coater, improve the production continuity.Reduce production costs, can reduce pollution environment.
