Description

Technical Field

[0001] The utility model relates to continuous turbulent pickling equipment, belonging to the technical field of hot-dip galvanizing pickling. Background Art

[0002] Hot-dip galvanizing, also known as hot-dip galvanizing or hot-dip galvanizing, is a surface treatment technique that deposits a zinc layer on the surface of steel components for aesthetic purposes and rust prevention. It is an effective method for metal corrosion protection. The hot-dip galvanizing process involves pickling the finished product, washing it with water, adding a galvanizing agent, drying it, rack plating it, cooling it, chemically treating it, cleaning it, polishing it, and finally hot-dip galvanizing it for completion. Before galvanizing, the workpiece is typically subjected to a pickling and rust removal process. This involves allowing the acid to react with the oxides on the metal surface, removing them from the metal. Currently, the pickling method used in the galvanizing industry for profiles such as angle steel and channel steel is static intermittent immersion pickling of the entire hoist. There are multiple acid tanks of different sizes on the work site, and an electric hoist is used to intermittently immerse the entire hoisted workpiece in multiple tanks for pickling. For example, Chinese patent CN 201720667767.9 is titled "A special lifting hanger device with fixed distance for hot-dip galvanizing pickling process." This pickling method has low efficiency, uneven pickling quality, requires a large number of people, and leaks acid mist, which poses a certain health hazard to operators and poses certain safety hazards.

[0025] The multiple workpieces arranged in a row are grouped together. The workpieces are arranged longitudinally along the conveying direction. Multiple groups of workpieces are arranged front and back, and are sequentially conveyed to the acid-resistant tank body 8 by the feeding roller 1; the acid in the acid storage tank 15 is pressurized by the acid circulation pump 13 and heated by the graphite heat exchanger 14, and then enters the acid-resistant tank body 8 through the front acid circulation inlet 7 and the rear acid circulation inlet 17, and enters the acid-resistant tank body 8 between the acid overflow profiling plate 1 5 and the acid overflow profiling plate 2 19; the acid-resistant and wear-resistant rubber roller 6 continuously conveys the workpiece 4, and the workpiece 4 sequentially passes through the acid mist overflow prevention plate 3, the acid overflow profiling plate 1 Plate 1 5, acid overflow profiling plate 2 19 and profiling hole 21 of acid mist overflow prevention plate 2 18.

After pickling, the workpiece 4 is continued to be transported to the next process by the discharge roller 9, thereby realizing continuous longitudinal pickling.

[0026] The acid liquid in the acid-resistant tank body 8 overflows into the acid-resistant tank body 8 between the acid mist overflow prevention plate 3 and the acid liquid overflow prevention plate 5 through the profiling hole of the acid liquid overflow profiling plate 1, and flows back to the acid liquid storage tank 15 through the acid liquid reflux port 10; the acid liquid in the acid-resistant tank body 8 overflows into the acid-resistant tank body 8 between the acid mist overflow prevention plate 2 18 and the acid liquid overflow profiling plate 2 19 through the profiling hole of the acid liquid overflow profiling plate 2, and flows back to the acid liquid storage tank 15 through the acid liquid reflux port 2 16.

[0027] The acid mist generated by the overflow of the acid solution is blocked by the acid mist overflow prevention plate 1 3 and the acid mist overflow prevention plate 2 18, thereby preventing the acid mist from leaking from the inlet and outlet of the acid-resistant tank body 8.

[0028] The acid mist overflow prevention plate 3 isolates the acid-resistant tank body 8 at the entrance into a feed space. After the workpiece 4 enters the acid-resistant tank body 8 through the entrance 22, it enters the subsequent process through the contoured holes of the acid mist overflow prevention plate 3. The acid mist overflow prevention plate 3 isolates and seals the acid mist in the acid-resistant tank body 8, preventing it from leaking out through the entrance. Due to the passage of the workpiece, the leakage of acid mist from the contoured holes of the acid mist overflow prevention plate 3 is extremely small. The acid mist overflow prevention plates 3 are multiple in number and are evenly distributed within the feed space. The multiple acid mist overflow prevention plates 3 further prevent the leakage of acid mist.

The workpiece 4 entering from the profiling hole of the acid overflow profiling plate 1 5 is pickled in the pickling space, and then enters the next process through the profiling hole of the acid overflow profiling plate 2 19. The acid enters the pickling space through the front acid circulation inlet 7 and the rear acid circulation inlet 17, and overflows through the profiling holes of the acid overflow profiling plate 1 5 and the acid overflow profiling plate 2 19.

The workpiece 4 entering from the profiling hole of the acid mist overflow prevention plate 19 enters the next process through the profiling hole of the acid liquid overflow profiling plate 18. The acid overflowing from the profiling hole of the acid liquid overflow profiling plate 19 flows back to the acid liquid storage tank 15 at the bottom of the acid liquid reflux space 2 through the acid liquid reflux port 16.

[0032] The acid mist overflow prevention plate 2 18 isolates the acid-resistant tank body 8 at the outlet into a discharge space. The workpiece 4 after pickling enters the discharge space through the shaped holes of the acid mist overflow prevention plate 2 18 and enters the subsequent process through the outlet 23. The acid mist overflow prevention plate 2 18 isolates and seals the acid mist in the acid-resistant tank body 8 to prevent leakage through the outlet. Since the shaped holes of the acid mist overflow prevention plate 2 18 have workpieces passing through them, leakage of acid mist is extremely small. The acid mist overflow prevention plate 2 18 is multiple in number and is evenly distributed in the discharge space. The multiple acid mist overflow prevention plates 2 18 further prevent leakage of acid mist.
