Description

Technical Field

[0001] The utility model belongs to the technical field of hot-rolled titanium plate pickling, and particularly relates to a circulating pickling device for hot-rolled titanium plates. Background Art

[0002] At present, the main purpose of hot-rolled titanium plate pickling is to remove the scale, mill scale and other surface contaminants generated during the hot-rolling process, so as to improve its surface quality and anti-corrosion performance.

[0003] After retrieval, there is a strip pickling circulating device with the authorized publication number of CN 109536980 A in the prior art. A plurality of cleaning mechanisms are installed inside the box body, a plurality of acid spraying mechanisms are installed at the top of the box body, and a collecting mechanism is installed inside the box body. When the steel plate moves inside the box body, an acid spraying mechanism sprays acid solution onto the surface of the steel plate, and a cleaning mechanism rotates to make the acid solution contact the steel plate to remove the oxide film on the surface of the steel plate. The acid solution after preliminary use falls into the inside of a collecting mechanism. At this time, the feeding mechanism inside the second acid spraying mechanism moves, and the acid solution inside the collecting mechanism is sucked into the second acid spraying mechanism again. The acid solution is sprayed onto the surface of the steel plate again through the second acid spraying mechanism, and the cleaning mechanism cleans the steel plate again. The acid solution after secondary use falls into the inside of another collecting mechanism for reuse; in this device, the acid solution is sprayed onto the strip surface through the nozzle. Due to the limitations of gravity and the nozzle position, even if the acid solution is made to contact the steel plate through the cleaning mechanism, there may be an uneven distribution of the acid solution on the strip surface. In particular, it is difficult to ensure sufficient acid solution coverage and contact on the lower surface of the strip, thus affecting the pickling effect.

[0004] After retrieval, there is a pickling device for TA10 titanium alloy hot continuous rolling strip with the authorized announcement number of CN 218812116 U in the prior art. The feeding port and the discharging port are respectively located at both ends of the pickling tank; both ends of the driving roller I are connected to the inner side wall of the pickling tank at one end of the feeding port through bearings. There is a driven roller I above the driving roller I, and a motor I is provided at one end of the driving roller I. The motor I is fixed on the outer side wall of the pickling tank; both ends of the driving roller II are connected to the inner side wall of the pickling tank at one end of the discharging port through bearings. There is a driven roller II above the driving roller II, and a motor II is provided at one end of the driving roller II; there is a pair of pressing rollers, both of which are connected to the inner side wall of the pickling tank between the driving roller I and the driving roller II. As the acid solution is recycled in this device, its concentration and purity will not only gradually decrease, but also be mixed with impurities, such as residues on the steel plate surface, debris generated during the brushing process, etc. These situations will not only reduce the pickling effect, but may even cause adverse effects on the steel plate surface. Summary of the Invention

[0013] The beneficial effects of the present utility model compared with the prior art are as follows:

The hub motors are arranged inside the upper and lower brush rollers in the scrubbing mechanism so that they can rotate by themselves.

[0016] 3) The motor II controls the transmission of the acid-resistant conveyor belt. The oxides and other impurities generated during pickling are taken out of the pickling tank in time through the acid-resistant conveyor belt and the baffles arranged on the acid-resistant conveyor belt. When the acid-resistant conveyor belt reaches the scrubbing tank, the water pipe is controlled by the angular stepping motor to reach the appropriate angle, and the high-pressure nozzle and the conveyor belt cleaning brush clean the acid-resistant conveyor belt.

The connecting rings and the connecting rods both use telescopic connecting rods with springs. The centrifugal force generated during rotation causes the three groups of connecting rods arranged on the connecting rings to expand and contract. The connecting rods make the rotation between the stirring rods have a certain lag through the telescopic connecting rods with springs. Through the cooperation between the connecting rods, irregular turbulence is generated by the stirring blades during the stirring process, so as to achieve the purpose of improving the stirring effect and the stirring efficiency.
