A mesh-like permeation element is provided at the higher end of the lower shell, with a certain gap between the mesh-like permeation element and the lower shell. A spiral component controlled by the motor is provided between the upper and lower shells. The spiral component has several through holes on its blades and includes a feed inlet and a discharge outlet. This pickling tank reduces the evaporation of the pickling solution and, through the action of the spiral component, not only improves pickling efficiency but also enables automatic discharge. A pickling production line using this pickling tank can achieve automated production, reducing labor costs and labor intensity while improving production efficiency.

[0004] Based on existing solutions and actual production and processing, existing pickling tanks have the following drawbacks, such as: they are not convenient for picking up and separating pickled objects for hanging, and they are not convenient for cleaning to prevent residue from the pickling tank. Therefore, this utility model provides a residue-proof pickling tank for pickling lines to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pickling tank for pickling lines that prevents residue buildup, thereby solving the problems mentioned in the background art, such as the inconvenience of handling and separating pickled objects, and the inconvenience of cleaning the pickling tank to prevent residue buildup.

[0017] 2. Equipped with a connecting plate and a hook, the horizontal frame is connected to the connecting plate by tightening the locking bolt. After the object to be pickled is hung on the hook, the limiting block on the outside of the connecting plate is aligned with the corresponding groove of the splash guard. After the lifting ring is connected to the lifting rope, the entire connecting plate is moved up and down by driving the lifting rope. The limiting block and the splash guard slide until the object suspended on the hook comes into contact with the pickling liquid inside the pickling tank, which facilitates the removal and separate suspension of the pickled object.

[0018] 3. Equipped with a scraper brush and guide assembly, the motor drives the guide rod to move, which in turn drives the guide block to move through the threaded part of the guide rod. The guide block drives the entire assembly to move in the left and right directions, causing the connecting rod to connect the clamping frame to the outer scraper brush, which then slides against the inner wall of the pickling tank. The scraper brush brushes the inner wall of the pickling tank. After the drain valve is opened, the wastewater is discharged from the drain pipe, facilitating the cleaning of the pickling tank to prevent residue. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a pickling tank for pickling line with anti-residue pickling, including a pickling tank body 1, a guide pipe 2 is provided on the left side of the pickling tank body 1, and a one-way liquid inlet valve 3 is installed inside the guide pipe 2, and also includes a liquid storage chamber 4 provided on the upper side of the guide pipe 2, and a filter screen 5 is installed on the inner side of the liquid storage chamber 4, and a splash guard 6 is provided on the upper side of the pickling tank body 1, and a limit block 7 is installed on the inner side of the splash guard 6;

[0027] A connecting plate 8 is installed inside the limiting block 7, and a connecting seat 9 is installed on the upper side of the connecting plate 8. A lifting ring 10 is installed on the upper side of the connecting seat 9. A horizontal frame 19 is installed on the lower side of the connecting plate 8. A locking bolt 20 is connected to the inner side of the horizontal frame 19. A hook 11 is installed on the lower side of the horizontal frame 19. A drain pipe 12 is installed on the right side of the pickling tank body 1. A drain valve 13 is installed inside the drain pipe 12.

[0028] A motor 14 is installed inside the pickling tank body 1, and a guide assembly 15 is provided on the left side of the motor 14. The guide assembly 15 includes a guide rod 1501 on the left side of the motor 14, and a fixing seat 18 is installed on the left side of the guide rod 1501. A guide block 1502 is provided on the outside of the guide rod 1501, and a connecting rod 1503 is installed on the outside of the guide block 1502. A fixing frame 16 is provided on the outside of the connecting rod 1503, and a scraper brush 17 is connected to the outside of the fixing frame 16. The assembly constitutes a pickling tank for pickling line to prevent residue.

[0029] like Figure 1As shown, the liquid storage chamber 4 and the filter screen 5 are locked together. The filter screen 5 is locked inside the liquid storage chamber 4, so that when the pickling solution is introduced from the top of the liquid storage chamber 4, it can be filtered through the holes inside the filter screen 5 first. After the one-way liquid inlet valve 3 is opened, the filtered pickling solution is guided by the guide pipe 2 and flows into the interior of the pickling tank body 1, which facilitates the filtration function of the pickling tank for the pickling solution.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the limiting block 7 and the splash guard 6 are slidably connected, and the limiting block 7 is set at an equal angle about the center of the connecting plate 8. The locking bolt 20 is threadedly connected to the horizontal frame 19 and the connecting plate 8, and the locking bolt 20 is set at an equal angle about the center of the horizontal frame 19. The hooks 11 are set at equal intervals on the horizontal frame 19. The horizontal frame 19 is placed on the lower side of the connecting plate 8, and the locking bolt 20 is tightened so that the horizontal frame 19 and the connecting plate 8 are connected by the locking bolt 20. After the object to be pickled is hung on the hook 11, the limiting block 7 on the outside of the connecting plate 8 is aligned with the corresponding groove of the splash guard 6, so that the lifting ring 10 is connected to the lifting rope. The entire connection of the connecting plate 8 is moved up and down by driving the lifting rope. The limiting block 7 and the splash guard 6 slide until the object suspended on the hook 11 comes into contact with the pickling liquid inside the pickling tank body 1, which facilitates the picking of the pickled object and separates and suspends it.

[0031] like Figure 1 and Figure 3As shown, the guide rod 1501 passes through the interior of the guide block 1502, and the connecting rod 1503 is set at an equal angle about the center line of the guide block 1502, and the connecting rod 1503 has an inclined structure. The longitudinal section of the clamping frame 16 is U-shaped, and the clamping frame 16 is relatively attached to the scraper brush 17. The scraper brush 17 is relatively slidably connected to the pickling tank body 1. After the pickling operation is completed, the cleaning solution is loaded inside the pickling tank body 1, and the motor 14 is turned on. The motor 14 drives the guide rod 1501 to move, so that the thread on the outside of the guide rod 1501 drives the guide block 1502 to move. The guide block 1502 is connected to the clamping frame 16 through the connecting rod 1503. The outer side of the scraper brush 17 on the outside of the clamping frame 16 is in close contact with the inner wall of the pickling tank body 1. 2. The vertical distance between the guide block 1502 and the pickling tank body 1 is less than the connection distance between the guide block 1502 and the pickling tank body 1 through the diagonal point of the scraper brush 17. When both the front and rear walls of the scraper brush 17 are in contact with the pickling tank body 1, it is difficult for the scraper brush 17 and the fixing frame 16 to deviate at an angle, thus preventing the guide block 1502 from rotating with the guide rod 1501. The guide block 1502 drives the whole to move in the left and right directions, so that the fixing frame 16 connected to the connecting rod 1503 drives the scraper brush 17 on the outside to slide and connect with the inner wall of the pickling tank body 1. The scraper brush 17 brushes the inner wall of the pickling tank body 1. After the drain valve 13 is opened, the sewage is discharged from the drain pipe 12, which facilitates the anti-residue cleaning of the pickling tank. This is the usage method of the anti-residue pickling tank for the pickling line.
