Description

Technical Field

[0001] The invention relates to the field of stainless steel strip pickling, and in particular to a stainless steel pickling liquid circulation supply mechanism and a stainless steel strip pickling device. Background Art

[0002] The pickling treatment of stainless steel strip is a necessary treatment stage after rolling, which aims to remove impurities and debris generated during the rolling process and make the surface of the stainless steel strip cleaner for subsequent processing and application.

[0003] At present, the mainstream pickling method adopts the immersion method, that is, immersing the stainless steel strip in the pickling solution to ensure that the impurities are fully in contact with the pickling solution and react, so as to achieve a thorough and comprehensive impurity removal effect on the stainless steel strip. However, as the impurities continue to dissolve in the pickling solution, the concentration of the pickling solution will gradually decrease, thereby affecting the efficiency of pickling. However, these low-concentration pickling solutions still have a certain utilization value. Directly replacing the pickling solution will undoubtedly cause a waste of resources. However, if it continues to be used, the time spent on treating the stainless steel strip with the pickling solution will increase in an additive manner, and there may even be impurity removal defects. Therefore, in view of this, we can only make a trade-off between replacing the pickling solution and continuing to use it. Summary of the invention

[0076] The stainless steel strip pickling device is used to pickle the stainless steel strip. First, pickling liquid is added to the pickling tank 8. The liquid level of the pickling liquid is higher than the height of the coil 10 and lower than the height of the adsorbent cotton 18. A reducing agent of the pickling liquid is added to the reaction box 1, and a supplementary acid agent of the pickling liquid is added to the conveying box 2. Next, the latch 1602 is pulled out, and the two loading rollers 16 on the left and right sides are removed. The stainless steel strip to be pickled is rolled onto the loading roller 16 of the right loading roller assembly, and the rewound stainless steel strip is rolled onto the loading roller 16 of the right loading roller assembly. The core is mounted on the loading roller 16 of the left loading roller assembly. After completion, the two loading rollers 16 can be reinstalled on the pickling tank 8 using the latch 1602. The end of the stainless steel strip coil is passed through each guide roller assembly, through the coil 10, through the two mounting shafts Y17 of each row of mounting shafts Y group, and through the two layers of fan blades 22 in the mounting frame Y21, and finally fixed on the core on the left loading roller assembly. At this point, all preparations for using the pickling device are completed;

[0077] Start the motor Y30, the loading roller 16 on the left rotates to reel in the stainless steel strip, and the loading roller 16 on the right releases the stainless steel strip, so that the stainless steel strip moves to the left as a whole; when the stainless steel strip moves to the position of the winding strip 10, the stainless steel strip will be brushed by the bristles 11 on the moving winding strip 10 to improve the efficiency and effect of removing impurities from the stainless steel strip; when the stainless steel strip moves to the position of the adsorption cotton 18, the rotating adsorption cotton 18 will adsorb the residual pickling liquid on the stainless steel strip, and at the same time, the pickling liquid adsorbed on the adsorption cotton 18 will be scraped off by the scraping surface 20 of the guide frame 19, and this part of the pickling liquid will flow into the cavity 190 of the guide frame 19 1, and is led out from the conduits 1902 on both sides, so as to flow back into the pickling tank 8. In particular, under the guidance of the conduit 1902, this part of the pickling liquid can bypass the stainless steel belt to prevent it from flowing back onto the stainless steel belt; when the stainless steel belt moves to the position of the fan blade 22, the stainless steel belt will be air-dried and dryly rolled up to facilitate the subsequent transportation and processing of the stainless steel belt coil; finally, when the entire roll of stainless steel belt coil is pickled and rolled up, the loading roller 16 on the left is removed to roll up the stainless steel belt coil; thereafter, the next stainless steel belt coil to be pickled can be loaded, and the above steps are repeated, and the cycle is repeated.

[0078] When the detector 36 detects that the concentration of the pickling solution is as low as the preset value, the control device in the detector 36 starts the motor X7 and directs the port of the ball valve 6 toward the branch pipe 5 on the reaction box 1. Therefore, the low-concentration pickling solution in the pickling tank 8 can enter the reaction box 1 through the middle pipe 4 and the branch pipe 5 for reduction. At the same time, the contact block 24 is turned to contact the sliding block 28, which will make the two terminals 27 contact and supply power to the controller 25. The controller 25 immediately controls the motor Y30 to turn off, and the guide roller 14, the fan blade 22, the installation shaft X9 and the installation shaft Y17 will no longer rotate, and the pickling device stops running;

[0079] When the pickling liquid is reduced, it will be transported to the conveying box 2 by the transition box 3. When the pickling liquid completes pH adjustment and element supplementation in the conveying box 2, the motor X7 is started again, and the port of the ball valve 6 is rotated toward the branch pipe 5 on the conveying box 2, and the conveying box 2 can re-transport the pickling liquid to the pickling tank 8. After completion, the port of the ball valve 6 is rotated to not face any branch pipe 5, thereby closing the middle pipe 4, so that the pickling tank 8 no longer leads to the reaction box 1 and the conveying box 2, that is, the stainless steel strip can continue to be pickled at this time; in the above process, the rotation of the ball valve 6 will also cause the contact block 24 to disengage from the sliding block 28, and the two terminals 27 will be separated, disconnecting the power supply to the controller 25, so the motor Y30 can restart to control the operation of the pickling device.
