Description

Technical Field

[0001] The utility model relates to the technical field of pickling rollers, in particular to a pickling immersion roller which can be raised and lowered. Background Art

[0002] In the cold rolling production process of steel plates, the first process is to pickle the raw steel coil. The purpose of pickling is to remove the oxide layer on the surface of the strip. The pickling section is required to not only remove the residual magnesium oxide powder on the surface of the steel strip, but also prevent over-pickling from damaging the magnesium silicate bottom layer formed during the high-temperature annealing process. Therefore, it is very important to control the surface of silicon steel. Over-pickling is never allowed, and the pickling time is extremely strict. When the pickling roller pickles the surface of silicon steel, the pickling roller is generally immersed in the acid solution, and then the silicon steel surface is pickled.

[0003] In the prior art, after the pickling roller pickles the surface of silicon steel, a large amount of impurities will be generated on the surface of the pickling roller. If the impurities are not removed, the impurities on the surface of the pickling roller will easily affect the smoothness of the subsequent pickling of the silicon steel and affect the pickling quality. Moreover, after the pickling roller is used for a long time, the surface of the pickling roller will produce greater wear. Since the pickling roller is generally an integrated structure, if the entire pickling roller structure is replaced, the maintenance cost is relatively high. Utility Model Content

[0031] When the semi-annular pickling roller 3 needs to be cleaned, the threaded lifting rod 11 is twisted to drive the cleaning pipe 12, the flushing nozzle 14 and the cleaning brush 13 to move downward. At the same time, the cleaning pipe 12 will stretch the telescopic shaft 10 and the telescopic pipe 9, which is conducive to ensuring the stability of the movement of the cleaning pipe 12, the flushing nozzle 14 and the cleaning brush 13 until the cleaning brush 13 contacts the surface of the semi-annular pickling roller 3. Under the premise that the water tank 5 is filled with clean water, the clean water in the water tank 5 is introduced into the telescopic pipe 9, the cleaning pipe 12 and the flushing nozzle 14 through the work of the water pump 8, and the flushing nozzle 14 will spray the clean water to the semi-annular pickling roller 3, and under the premise that the motor 16 drives the rotating shaft 17, the positioning plate 18, the mounting roller 2 and the semi-annular pickling roller 3 to rotate, the multiple flushing nozzles 14 will spray the cleaning water evenly and comprehensively to the surface of the semi-annular pickling roller 3, so that the impurities on the surfaces of the two semi-annular pickling rollers 3 can be easily cleaned, and the cleaning brush 13 is conducive to sweeping and cleaning the surfaces of the two semi-annular pickling rollers 3, so that the impurities on the surfaces of the two semi-annular pickling rollers 3 can be easily cleaned, so as to prevent the impurities from affecting the smoothness of the semi-annular pickling roller 3 for subsequent silicon steel pickling, and effectively ensure the pickling quality of the silicon steel.

[0032] like Figure 1-6As shown, in this embodiment, the left and right ends of the installation roller 2 are fixed with positioning plates 18, the middle end of the inner wall of the semi-annular pickling roller 3 is fixed with a docking block 20, the upper and lower ends of the installation roller 2 are provided with docking ports 19 matching the docking blocks 20, the left and right ends of the docking blocks 20 are provided with positioning components, the positioning components include a spring return rod 22 and a card ball 23, the left and right ends of the inner wall of the docking port 19 are provided with contraction grooves 21, the spring return rods 22 are fixed in the contraction grooves 21, and the card balls 23 are connected At the end of the spring return rod 22, the left and right ends of the docking block 20 are both provided with arc-shaped grooves 24 matching the card ball 23, the left and right ends of the inner wall of the semi-annular pickling roller 3 are fixed with locking blocks 27, and the left and right sides of the upper and lower ends of the mounting roller 2 are both provided with locking grooves 25 matching the locking block 27, and the outer side of the locking block 27 is provided with a threaded locking hole 28, and the inner thread of the threaded locking hole 28 is connected with a threaded locking rod 26, and the threaded locking rod 26 is threaded outward and passes through the mounting roller 2 and the positioning plate 18 in sequence.
