The invention has the beneficial effects as follows: the fast acid cleaning device and the method that 1, provide a kind of cold rolled strip, conventional turbulent flow acid cleaning process basis adds ultrasonic technique, accelerate pickling speed, save the use of acid solution, thus save production cost; 2, because ultrasonic intensity regulates reaction fast, therefore better can prevent overpickling, owe the appearance of the defects such as pickling, make the pickling controllability of cold rolled strip high; 3, ultrasonic wave can play the effect improving pickling speed of response, and acid solution heating unit therefore can not be used to heat pickle solution, reduces equipment investment cost.
Accompanying drawing explanation
Fig. 1 is the front view of one embodiment of the invention.
Fig. 2 is the side-view of one embodiment of the invention.
Wherein: 1. pickling tank, 2. groove lid, 3. overflow groove, 4. container for storing liquid, 5. liquid-inlet pipe, 6. liquid returning tube, 7. recycle pump, 8. jet pipe, 9. ultrasonic generator, 10. transverter.
Embodiment
For understanding the present invention better, below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1-2, a kind of fast acid cleaning device of cold rolled strip, comprise pickling tank 1, groove lid 2 and the pickling recycle system, groove lid is made up of steel plate, the both sides top groove of its two side bottom and pickling tank forms water-lute, is provided with gap, cold rolled strip is passed therethrough bottom the two ends of groove lid with top, pickling tank two ends, groove lid both sides are connected with hydraulic efficiency system, by hydraulic efficiency system automatic vertical unlocking; Pickling tank is welded by certain thickness stainless-steel sheet, inner line with rubber, acid corrosion-resistant, anti-corrosion brick is laid on bottom pickling tank and both sides, prevents acid solution from corroding pickling tank, and heat-insulation and heat-preservation, the two ends of pickling tank are also provided with overflow groove 3, collect and backflow for pickling, isopipe root has hole for back flow, and two side has inlet opening with pickling tank; The pickling recycle system comprises container for storing liquid 4, liquid-inlet pipe 5 and liquid returning tube 6, the side that liquid-inlet pipe is connected with container for storing liquid is provided with recycle pump 7, opposite side is connected with jet pipe 8 respectively, jet pipe enters in pickling tank by inlet opening, liquid returning tube two ends are connected with hole for back flow respectively, be connected with container for storing liquid in the middle part of liquid returning tube, recovered acid washing lotion reuses; Also comprise ultrasonic unit, ultrasonic unit comprises ultrasonic generator 9 and transverter 10, and transverter uniform intervals is located at the top of groove lid, and it is connected by cable with ultrasonic generator; The outer wall of pickling tank lays ultrasonic absorption film, prevents ultrasonic wave to the injury of human body.
This device is adopted to carry out being with the method for the quick pickling of steel, cold rolled strip enters pickling tank 1 vertically, pickle solution in container for storing liquid 4 enters in liquid-inlet pipe 5 at the flows by action of recycle pump 7, sprayed by jet pipe 8 again and pickling is carried out to cold rolled strip, start ultrasonic generator 9, electrical signal is launched to transverter 10, transverter is driven to launch ultrasonic wave to pickling tank, pickle solution produces cavitation effect, dirt on cold rolled strip is peeled off, also pickling chemical reaction velocity can be made to accelerate, cold rolling more quickly by pickling, overflow groove 3 is entered when pickle solution overflows pickling tank, liquid returning tube 6 is entered by hole for back flow, finally be back in container for storing liquid and recycle.
When there is ultrasonic wave in acid solution, liquid generation ultrasonic vibration will be made, in the circulation that liquid internal increases for pressure instantaneous reduction, when pressure reduces suddenly, acid solution inside can form the little hole of many vacuum, the gas be dissolved in acid solution can be inhaled in hole and form small bubbles, but after small bubbles are formed, pressure increases suddenly and oppressed, there is time generation shockwave, these shockwave occur in belt steel surface makes effects on surface iron scale produce shock action on the one hand, the stripping of accelerating oxidation iron, promote that stirring action is played on surface on the other hand, accelerate belt steel surface pickling reaction reactant and product ion diffusion, thus greatly promote the carrying out of pickling.
By hyperacoustic cavitation effect principle, accelerate the mobility of acid solution, make belt steel surface acid solution change liquid speed to accelerate, thus accelerate pickling chemical reaction velocity, reduce the use of current pickle solution, improve whole unit speed further, because ultrasonic intensity regulates reaction fast, therefore better can prevent overpickling, owe the appearance of the defects such as pickling, make acid washing method controllability of the present invention high.
