Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel strip pickling, in particular to a pickling device for high-precision stainless steel strip processing. Background Art

[0002] Stainless steel strip is simply an extension of ultra-thin stainless steel plate. It is a narrow and long steel plate produced mainly to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. During the production process of stainless steel strip, it will produce surface oxide scale, welding slag, oil stains and other impurities, so pickling equipment is needed to clean and remove these rust and dirt impurities on the surface of the stainless steel strip, making the surface of the stainless steel strip smoother and cleaner, improving its aesthetics, and facilitating the subsequent processing of the steel strip.

[0003] The existing pickling equipment will leave a large amount of moisture on the surface of the stainless steel strip after pickling. For example, a two-stage pickling and rust removal device for stainless steel strip disclosed in the announcement number CN209113997U does not have a drying function to dry the moisture on the surface of the stainless steel strip in time after pickling. If the residual moisture is not removed in time, it may cause the stainless steel strip to rust or oxidize during subsequent storage or processing, affecting its quality and performance. Therefore, if the stainless steel strip after pickling by this device needs to be dried, it is necessary to take the stainless steel strip out of the pickling and rust removal device and put it into another drying equipment for processing. This transfer process not only increases the operation time, but may also cause secondary pollution or damage due to improper operation during the transfer process.

[0004] Therefore, it is necessary to invent a high-precision stainless steel strip processing pickling equipment to solve the above problems. Utility Model Content

A No. 1 high-pressure nozzle 12 is arranged above the No. 2 conveying roller 9, and a No. 2 high-pressure nozzle 13 is arranged below the No. 2 conveying roller 9. There are multiple No. 1 high-pressure nozzles 12 and No. 2 high-pressure nozzles 13. A water injection pipe 11 is connected between the No. 1 high-pressure nozzle 12 and the No. 2 high-pressure nozzle 13, and a water guide pipe 10 is connected to the water inlet end of the water injection pipe 11. The No. 1 high-pressure nozzle 12, the No. 2 high-pressure nozzle 13, the water injection pipe 11 and the water guide pipe 10 are connected.

[0027] The pickling chamber 5 is provided for soaking the stainless steel strip in pickling liquid to remove impurities such as oxide scale, welding slag, oil stains, etc. on its surface, and the soaked stainless steel strip is then rinsed with high-pressure spray of clean water through the No. 1 high-pressure nozzle 12 and the No. 2 high-pressure nozzle 13 inside the spray chamber 8.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual Figure 1-3 When using the utility model, the stainless steel strip to be cleaned is first unwound through the unwinding wheel 3, and one end of the stainless steel strip is placed in the pickling chamber 5 through the No. 1 conveying roller 7. The stainless steel strip placed in the pickling chamber 5 is submerged by the pickling liquid, so that the stainless steel strip is soaked in the pickling liquid, and some impurities on the surface of the stainless steel strip after soaking will fall off, and then placed in the spray chamber 8 through the No. 2 conveying roller 9. After the soaked stainless steel strip is placed in the spray chamber 8, the water guide pipe 10 is connected to the external water pump, and the water pump inputs clean water into the water guide pipe 10 and guides it to the water injection pipe 11, so that the No. 1 high-pressure nozzle 12 and the No. 2 high-pressure nozzle 13 perform high-pressure spraying of clean water on the upper and lower surfaces of the stainless steel strip, thereby further removing the residual impurities remaining on the surface of the stainless steel strip;

[0032] Refer to the instruction manual Figure 4-5 When using the utility model, the cleaned stainless steel strip passes through the lower water absorption roller 17 and the upper water absorption roller 16 to absorb part of the moisture on the upper and lower surfaces. The stainless steel strip that has absorbed moisture is finally conveyed to the inside of the drying chamber 18 by the No. 3 conveying roller 19. Thus, the fan 20 and the electric heating plate 21 in the drying chamber 18 can dry the upper and lower surfaces of the stainless steel strip. The dried stainless steel strip is reeled up by the reeling wheel 2. Therefore, the continuous process flow is also conducive to reducing manual operations and reducing labor costs.
