Description

Technical Field

[0001] This utility model relates to the field of pickling tank technology, and in particular to a galvanized pickling tank. Background Technology

[0002] Pickling steel parts removes rust, but the acid reacts with the iron substrate, affecting the original thickness and strength of the steel parts. Traditional methods to prevent over-pickling involve controlling the pickling time, but this results in uneven pickling, low acid flow rate, and reduced pickling efficiency. In addition, it also leads to poor pickling continuity and easy splashing and contamination of the workpiece surface after pickling. Therefore, there is an urgent need to design a galvanized pickling tank to solve the above problems. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a zinc plating pickling tank.

[0004] One of the objectives of this utility model is achieved through the following technical solution: A zinc-plating pickling tank includes a tank body. A first support is welded to the front side of the tank body, and a drive motor is mounted on the first support. A reducer is driven to the power output end of the drive motor, and a rotating shaft is fixedly connected to the power output end of the reducer. The rear end of the rotating shaft is rotatably connected to the rear wall of the inner cavity of the tank body. Two symmetrical rotating rings are sleeved on the outer side of the rotating shaft, and four fixed rods arranged in a cross shape are fixedly connected to the inner wall of the rotating rings. The other end of each fixed rod is fixedly connected to the outer wall of the rotating shaft. Four lifting rods are rotatably connected between the two rotating rings, and several hooks are rotatably connected to each lifting rod. A swing mechanism is provided at the bottom of the inner cavity of the tank body.

[0005] Furthermore, the swing mechanism includes a first rotating rod located directly below the rotating shaft. A first sealed bearing is provided near the bottom of the front side of the groove, and a second bracket is welded to the bottom of the front side of the groove. A servo motor is mounted on the second bracket. The rear end of the first rotating rod is rotatably connected to the rear wall of the inner cavity of the groove, and the front end of the first rotating rod penetrates the inner cavity of the first sealed bearing and is fixedly connected to the power output end of the servo motor. Two first connecting rods distributed front and rear are fixedly connected to the outer wall of the first rotating rod, and the other ends of the two first connecting rods are fixedly connected to the same first impact rod.

[0006] Furthermore, a second rotating rod is rotatably connected to the rear wall of the inner cavity of the groove near the upper left corner. A second sealed bearing is provided on the front side of the groove near the upper left corner, and the front end of the second rotating rod passes through the inner cavity of the second sealed bearing and is fixedly connected to a driven groove wheel. A transmission groove wheel is sleeved and fixedly connected to the outer wall of the first rotating rod near the front end. A belt is provided between the transmission groove wheel and the driven groove wheel, and the transmission groove wheel and the driven groove wheel are connected by belt drive. Two second connecting rods distributed front and rear are fixedly connected to the outer wall of the second rotating rod, and the other end of the two second connecting rods is fixedly connected to the same second impact rod.

[0007] Furthermore, several blades are uniformly fixedly connected to the outer wall of the rotating ring.

[0008] Furthermore, both rotating rings are located within the inner cavity of the groove, and the two rotating rings are arranged symmetrically about the central axis of the groove.

[0009] Furthermore, the four booms are arranged in a cross-shaped array.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The drive motor and reducer drive the rotating shaft to rotate slowly and uniformly, which in turn drives the rotating ring to rotate clockwise through the fixed rod, thereby driving the workpiece suspended on the hook to rotate. After the workpiece is immersed in the pickling solution in the pickling tank, it is pickled. The four hanging rods arranged in a cross array can cycle for feeding, pickling and unloading, thus realizing continuous pickling operation.

[0011] 2. By rotating the rotating ring and driving several paddles to rotate synchronously, the paddles agitate the pickling solution, causing the pickling solution to fluctuate in the pickling tank, so that the pickling solution is always in a flowing state, thereby improving the pickling effect on the workpiece.

[0012] 3. The first rotating rod is driven to rotate by a servo motor, and the first impact rod is driven to rotate clockwise by a connecting rod. When one of the lifting rods is at the bottom of the rotating ring, the first impact rod can push the hook to shake during rotation, so that the workpiece on the hook collides with the pickling solution, thereby agitating the pickling solution and further improving the pickling effect. In addition, the second rotating rod can be driven to rotate by the transmission connection of the drive pulley, belt and driven pulley, and the second impact rod can be driven to impact and shake the workpiece after pickling, so as to shake off the pickling solution on the surface of the workpiece. This not only avoids the waste of pickling solution, but also avoids the pickling solution dripping onto the outside of the pickling tank and causing pollution when the workpiece is removed.

[0013] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figures 1 to 3 The present invention provides the following technical solution: A galvanizing pickling tank includes a tank body 1. A first support 2 is welded to the front side of the tank body 1, and a drive motor 3 is mounted on the first support 2. A reducer 21 is driven to the power output end of the drive motor 3, and a rotating shaft 4 is fixedly connected to the power output end of the reducer 21. The rear end of the rotating shaft 4 is rotatably connected to the rear wall of the inner cavity of the tank body 1. Two symmetrical rotating rings 6 are sleeved on the outer side of the rotating shaft 4, and four fixed rods 5 arranged in a cross shape are fixedly connected to the inner wall of the rotating rings 6. The other end of each fixed rod 5 is fixedly connected to the outer wall of the rotating shaft 4. Four lifting rods 7 are rotatably connected between the two rotating rings 6, and several hooks 8 are rotatably connected to each lifting rod 7. The hooks 8 can rotate at a certain angle on the lifting rods 7, so that the workpiece can swing. A swing mechanism is provided at the bottom of the inner cavity of the tank body 1.

[0020] The swing mechanism includes a first rotating rod 10, which is located directly below the rotating shaft 4. A first sealed bearing is provided on the front side of the tank 1 near the bottom, and a second bracket 16 is welded on the front side of the tank 1 near the bottom. A servo motor 17 is provided on the second bracket 16. The rear end of the first rotating rod 10 is rotatably connected to the rear wall of the inner cavity of the tank 1, and the front end of the first rotating rod 10 passes through the inner cavity of the first sealed bearing and is fixedly connected to the power output end of the servo motor 17. Two first connecting rods 11 are fixedly connected to the outer wall of the first rotating rod 10, and the other end of the two first connecting rods 11 is fixedly connected to the same first impact rod 12. When the servo motor 17 is started to drive the first rotating rod 10 to rotate, it can drive the first impact rod 12 to rotate clockwise, thereby pushing the hook 8 and causing the workpiece to shake, so that the workpiece collides with the fluctuating pickling solution, thereby improving the pickling effect.

[0021] A second rotating rod 13 is rotatably connected to the rear wall of the inner cavity of the tank 1 near the upper left corner. A second sealed bearing is provided on the front side of the tank 1 near the upper left corner, and the front end of the second rotating rod 13 passes through the inner cavity of the second sealed bearing and is fixedly connected to a driven grooved wheel 19. A transmission grooved wheel 18 is sleeved and fixedly connected to the outer wall of the first rotating rod 10 near the front end. A belt 20 is provided between the transmission grooved wheel 18 and the driven grooved wheel 19, and the transmission grooved wheel 18 and the driven grooved wheel 19 are connected by the belt 20. Two second connecting rods 14 distributed front and rear are fixedly connected to the outer wall of the second rotating rod 13. Furthermore, the other ends of the two second connecting rods 14 are fixedly connected to the same second impact rod 15. When the servo motor 17 drives the first rotating rod 10 to rotate, it can drive the transmission groove wheel 18 to rotate, and drive the driven groove wheel 19 to rotate through the belt 20. The rotation of the driven groove wheel 19 drives the second rotating rod 13 to rotate, and the rotation of the second rotating rod 13 drives the second impact rod 15 to rotate clockwise and push the hook 8, thereby causing the workpiece on the hook 8 to shake, and thus shake off the pickling solution adhering to the workpiece, avoiding waste of pickling solution and preventing pickling solution from dripping into the outside of the pickling tank and causing pollution.

[0022] Several blades 9 are uniformly fixedly connected to the outer wall of the rotating ring 6. When the rotating ring 6 rotates, the blades 9 can be used to agitate the pickling solution, thereby achieving continuous flow of the pickling solution.

[0023] Both rotating rings 6 are located inside the cavity of the tank 1, and the two rotating rings 6 are arranged symmetrically about the central axis of the tank 1.

[0024] The four lifting rods 7 are arranged in a cross array. The rotating ring 6 drives the lifting rods 7 to rotate synchronously, thereby realizing the synchronous loading, pickling and unloading of workpieces, which is suitable for large-scale pickling operations.

[0025] Working Principle: In use, the operator first injects an appropriate amount of pickling solution into the tank 1. Then, the operator suspends the workpiece to be pickled on the uppermost hook 8. Next, the drive motor 3 and reducer 21 are started. The drive motor 3 drives the rotating shaft 4 to rotate, and the reducer 21 allows the rotating shaft 4 to rotate slowly, thereby causing the rotating ring 6 to rotate clockwise and immersing the workpiece in the pickling solution for pickling. The rotation of the rotating ring 6 drives several paddles 9 to rotate, thus agitating the pickling solution and achieving its flow. When the workpiece is at the bottom of the rotating ring 6, the servo motor 17 is started to drive the first rotating rod 10 to rotate. The rotation of the first rotating rod 10 causes the first impact rod 12 to rotate clockwise and... The hook 8 is pushed to shake, causing the workpiece to collide with the pickling solution, thus improving the pickling effect. Subsequently, the servo motor 17 is started to drive the first impact rod 12 to reset. After pickling is completed, the workpiece is driven to the top of the pickling tank. Under the transmission of the drive wheel 18, driven wheel 19 and belt 20, the second rotating rod 13 is driven to rotate, and the second impact rod 15 is driven to push the workpiece to shake, thereby shaking off the pickling solution on the surface of the workpiece. This avoids the pickling solution dripping onto the outside of the pickling tank and causing pollution during the removal of the workpiece. Through the continuous rotation of the rotating ring 6, the workpiece can be pickled on the bottom hook 8, and the workpiece can be reloaded on the top hook 8 and removed from the left hook 8. This can be used for large-scale workpiece pickling operations, improving the practicality of the pickling tank.

[0026] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
