[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-5 A rust removal device for scrap steel includes: a rust removal frame 1 and a drain pipe 21. A hydraulic rod 5 is installed on the inner wall of the rust removal frame 1. One end of the hydraulic rod 5 is connected to a rust removal outer cylinder 2. An operation hole 16 is opened on the top of the rust removal outer cylinder 2. A liquid filling pipe 10 and a water filling pipe 8 are respectively installed on the top of the rust removal outer cylinder 2. A motor 4 is installed on the outer wall of the rust removal outer cylinder 2. The output shaft of the motor 4 is connected to a rotating shaft 15. One end of the rotating shaft 15 is connected to a rust removal screen cylinder 17. A cylinder cover 13 is movably connected to the top of the rust removal screen cylinder 17.

[0021] Both the top of the cylinder cover 13 and the top of the rust-removing screen cylinder 17 are equipped with pins 18. The inner wall of the pins 18 is movably connected with threaded rods 19. The inner wall of the rust-removing screen cylinder 17 is equipped with bristles 20. The top of the rust-removing frame 1 is fixedly connected with a gear frame 12. The outer wall of the rust-removing outer cylinder 2 is equipped with a gear shaft 6. The outer wall of the gear shaft 6 is connected with a gear 7. The inner bottom wall of the rust-removing frame 1 is provided with a sliding groove 11 and a pipe movable hole 14. The bottom of the rust-removing outer cylinder 2 is connected with a slider 22. During the pickling and rust removal process of scrap steel, the scrap steel can be rotated and screened left and right. At the same time, the surface of the scrap steel can be brushed, which fully expands the contact range between the surface of the scrap steel and the pickling solution, thereby further improving the uniformity of pickling of scrap steel and further improving the rust removal efficiency of scrap steel.

[0022] The inner wall of the pin 18 is provided with internal threads, and the threaded rod 19 is threadedly connected to the pin 18 through the internal threads. The threaded connection between the threaded rod 19 and the pin 18 can fix the position of the cover 13 when the rust removal screen cylinder 17 is closed, which can prevent scrap steel from falling out of the rust removal screen cylinder 17, thus facilitating the rotation and movement of the rust removal screen cylinder 17 during the pickling and rust removal process.

[0023] The inner walls of the liquid addition pipe 10 and the water addition pipe 8 are both fitted with pipe plugs 9, and the inner wall of the operation hole 16 is fitted with a cover plate 3. This improves the sealing performance of the rust removal device during use, prevents the odor of the pickling solution from spreading out during the pickling process and causing adverse effects on the surrounding workers, and further facilitates its use.

[0024] The inner wall of the rust-removing outer cylinder 2 is provided with a sleeve, and the inner wall of the sleeve is movably connected to a support shaft. One end of the support shaft is fixedly connected to the outer wall of the rust-removing screen cylinder 17. When the motor 4 drives the rust-removing screen cylinder 17 to rotate through the rotating shaft 15, the rust-removing screen cylinder 17 drives the support shaft to rotate synchronously inside the sleeve, which further improves the stability of the rust-removing screen cylinder 17 during rotation.

[0025] Among them, the shape and size of gear 7 are matched with the shape and size of gear frame 12, and gear 7 is meshed with gear frame 12. When hydraulic rod 5 works to drive the rust removal outer cylinder 2 to move horizontally left and right in the rust removal frame 1, it can simultaneously drive gear 7 to move on gear frame 12, thereby improving the stability of the movement of rust removal outer cylinder 2.

[0026] The inner wall of the slide groove 11 is slidably connected to the outer wall of the slider 22, and the rust-removing outer cylinder 2 is slidably connected to the rust-removing frame 1. When the rust-removing outer cylinder 2 moves, it drives the slider 22 to slide in the slide groove 11, thereby supporting the movement of the rust-removing outer cylinder 2.

[0027] The brush bristles 20 are multiple and arranged in a ring array inside the rust removal cylinder 17. By setting multiple brush bristles 20, the pickling liquid on the scrap steel can be brushed on, and the rust on the scrap steel can also be brushed and cleaned, further improving the rust removal effect on the scrap steel.

[0028] Among them, the diameter of the drain pipe 21 is smaller than the diameter of the pipe movable hole 14, and one end of the drain pipe 21 extends to the bottom of the rust removal frame 1 through the pipe movable hole 14. It can discharge the waste liquid and wastewater in the rust removal outer cylinder 2 without affecting the horizontal movement of the rust removal outer cylinder 2. It can drive the drain pipe 21 to move in the pipe movable hole 14 at the same time when the rust removal outer cylinder 2 moves.

[0029] Working principle: When pickling and rust removal of small-volume scrap steel is required, the scrap steel is placed into the rust removal screen cylinder 17. After placement, the rust removal screen cylinder 17 is closed with the cylinder cover 13. The threaded rod 19 is inserted into the pin 18, and the threaded rod 19 is rotated to its position within the pin 18 to fix the position of the cylinder cover 13 when the rust removal screen cylinder 17 is closed. Then, the operating hole 16 is closed with the cover plate 3, and an appropriate amount of pickling solution is added to the rust removal outer cylinder 2 through the liquid addition pipe 10. This allows the scrap steel in the rust removal screen cylinder 17 to be soaked and rust removed. Simultaneously, the motor 4 can be turned on to make the rotating shaft 15 drive the rust removal screen cylinder 17 to rotate within the rust removal outer cylinder 2, thereby improving the position of the scrap steel. The rotating mechanism improves the uniformity of pickling scrap steel. Simultaneously, as the scrap steel rotates within the rust-removing outer cylinder 2, its surface comes into contact with the brush bristles 20. These bristles then coat the surface of the scrap steel with the pickling solution and brush away the rust, further enhancing the rust removal effect. Additionally, the hydraulic rod 5 can be activated to move the rust-removing outer cylinder 2 horizontally within the rust-removing frame 1. This movement of the outer cylinder 2, along with the rust-removing mesh cylinder 17, facilitates changes in the position of the scrap steel and expands the flow of the pickling solution, increasing the contact area between the pickling solution and the scrap steel, thus further improving the pickling and rust removal effect.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
