Description

Technical Field

[0001] This utility model relates to the field of pickling equipment, specifically an energy-saving and high-efficiency pickling tank for stainless steel pipes. Background Technology

[0002] Stainless steel pickling is an industrial cleaning technology that typically uses pickling and passivation paste and pickling and passivation solution. The pickling and passivation paste performs pickling and passivation simultaneously, with the aim of removing oxides and other contaminants from the stainless steel surface to achieve a uniform silvery-white finish. The principle of pickling is to use acid solutions to remove oxide scale and rust from the steel surface, forming salts through chemical reactions that dissolve in the acid solution and are removed.

[0003] Stainless steel pickling is generally carried out in a pickling tank. Inside the pickling tank, the acid comes into contact with the stainless steel and is consumed by the reaction. At this time, when the subsequent steel pipe enters, the acid concentration near the steel pipe is greatly reduced. Therefore, during pickling, it is necessary to use power to drive the acid inside the pickling tank to make the acid away from the stainless steel come into contact with it, so as to prevent the problem of incomplete pickling caused by incomplete contact between the acid and the stainless steel. However, the flow of acid requires additional energy, resulting in energy waste. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving and efficient pickling tank for stainless steel pipes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and high-efficiency pickling tank for stainless steel pipes, comprising a base plate, a pickling tank fixedly mounted on the top of the base plate, a hydraulic rod fixedly mounted on the top of the base plate, a T-shaped rod fixedly mounted on the top of the hydraulic rod, a fixing plate fixedly mounted on the lower end of the T-shaped rod, a fixing mechanism for conveniently fixing stainless steel pipes provided at the bottom end of the fixing plate, a rotating shaft movably embedded in the center of the bottom end of the pickling tank, a stirring rod fixedly mounted on the outside of the rotating shaft, a torsion spring fixedly mounted on the outside of the rotating shaft, and a stirring rod fixedly mounted on the outside of the rotating shaft. A winding wheel is fixedly installed around the side of the pickling tank, and a movable roller is installed on one side of the bottom end of the pickling tank. A steel wire rope is fixedly installed around the outside of the winding wheel. In use, when the hydraulic rod is at its highest position, the torsion spring is in a tightened state. The steel pipe is placed on the fixed mechanism, and then the hydraulic rod moves downward. At this time, the torsion spring resets, drives the rotating shaft to rotate, and at the same time drives the winding wheel to rotate, winding the steel wire rope around the outside of the winding wheel. The rotation of the rotating shaft drives the stirring rod to rotate and stir the acid solution, thereby preventing uneven distribution of acid concentration. Moreover, no additional power is required, achieving an energy-saving effect.

[0006] Preferably, the fixing mechanism includes a U-shaped plate and fixing rings. The U-shaped plate is slidably disposed on the outside of the fixing plate. There are two U-shaped plates, symmetrically disposed on both sides of the fixing plate. The fixing rings are fixed at the bottom of the U-shaped plate. The fixing rings located in the same plane are fixed to each other. In use, the steel pipe is inserted into the fixing ring and the fixing ring is used to fix the position of the steel pipe. Then, the U-shaped plate is slidably installed on the outside of the fixing plate so that the steel pipe is located at the lower end of the fixing plate. When the hydraulic rod moves downward, it drives the steel pipe into the pickling tank to facilitate the pickling work of the steel pipe. After completion, the hydraulic rod is reset and the U-shaped plate is removed to remove all the steel pipes.

[0007] Preferably, there are two hydraulic rods, which are symmetrically fixed on both sides of the top of the base plate.

[0008] Preferably, the rotating shaft and the pickling tank are in a movable sealed contact.

[0009] Preferably, the torsion spring is mosquito coil shaped, and the outermost part of the torsion spring is fixed to the bottom of the pickling tank.

[0010] Preferably, the wire rope passes around the bottom of the movable roller and is then fixed upwards to the lower end of the T-shaped rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When the hydraulic rod is at its highest position, the torsion spring is in a tightened state. The steel pipe is placed on the fixed mechanism. Then the hydraulic rod moves downward, and the torsion spring resets, driving the rotating shaft to rotate. At the same time, the winding wheel rotates, and the wire rope is wound around the outside of the winding wheel. The rotation of the rotating shaft drives the stirring rod to rotate and stir the acid solution, thereby preventing uneven distribution of acid concentration. Moreover, no additional power is required, achieving an energy-saving effect.

[0013] 2. In use, the steel pipe is inserted into the fixing ring to fix its position. Then, the U-shaped plate is slidably installed on the outside of the fixing plate so that the steel pipe is located at the lower end of the fixing plate. When the hydraulic rod moves downward, it drives the steel pipe into the pickling tank, which facilitates the pickling of the steel pipe. After completion, the hydraulic rod is reset and the U-shaped plate is removed to remove all the steel pipes. Attached Figure Description

T-shaped rods 4 are bolted to the top of the hydraulic rods 3. A fixing plate 5 is bolted to the lower end of the T-shaped rods 4. The bottom of the fixing plate 5 has a fixing mechanism for easily fixing stainless steel pipes. A rotating shaft 8 is movably embedded in the center of the bottom of the pickling tank 2. The rotating shaft 8 and the pickling tank 2 are in a movable sealed contact. A stirring rod 9 is welded to the outside of the rotating shaft 8. A torsion spring 13, shaped like a mosquito coil, is welded to the outside of the rotating shaft 8. The outermost part of the torsion spring 13 is welded to the pickling tank 2. At the bottom, a winding wheel 12 is welded and fixed around the outside of the rotating shaft 8. A movable roller 11 is installed on one side of the bottom of the pickling tank 2. A steel wire rope 10 is fixed around the outside of the winding wheel 12. The steel wire rope 10 passes around the bottom of the movable roller 11 and is then fixed upwards to the lower end of the T-shaped rod 4. When the hydraulic rod 3 is at its highest position, the torsion spring 13 is in a tightened state, and the steel pipe is placed on the fixed mechanism. Then the hydraulic rod 3 moves downward, at which point the torsion spring 13 resets, driving the rotating shaft 8 to rotate, and at the same time driving the winding wheel 12 to rotate, winding the steel wire rope 10 around the outside of the winding wheel 12. The rotation of the rotating shaft 8 drives the stirring rod 9 to rotate to stir the acid solution, thereby preventing uneven distribution of acid concentration and achieving energy saving without the need for additional power.

[0021] The fixing mechanism includes a U-shaped plate 6 and a fixing ring 7. The U-shaped plate 6 slides on the outside of the fixing plate 5. There are two U-shaped plates 6, symmetrically located on both sides of the fixing plate 5. The fixing ring 7 is welded and fixed to the bottom of the U-shaped plate 6. The fixing rings 7 located in the same plane are welded and fixed to each other. In use, the steel pipe is inserted into the fixing ring 7 and the fixing ring 7 is used to fix the position of the steel pipe. Then, the U-shaped plate 6 is slidably installed on the outside of the fixing plate 5 so that the steel pipe is located at the lower end of the fixing plate 5. Then, when the hydraulic rod 3 moves downward, it drives the steel pipe into the pickling tank 2, which facilitates the pickling of the steel pipe. After completion, the hydraulic rod 3 is reset and the U-shaped plate 6 is removed to remove all the steel pipes.

[0022] Working principle: When the hydraulic rod 3 is at its highest position, the torsion spring 13 is in a tightened state, placing the steel pipe on the fixed mechanism. Then, the hydraulic rod 3 moves downward, at which point the torsion spring 13 resets, driving the rotating shaft 8 to rotate, and simultaneously driving the winding wheel 12 to rotate, winding the steel wire rope 10 onto the outside of the winding wheel 12. The rotation of the rotating shaft 8 drives the stirring rod 9 to rotate, stirring the acid solution, thus preventing uneven distribution of acid concentration. No additional power is required, achieving energy saving. During use, the steel pipe is inserted into the fixing ring 7, which fixes the position of the steel pipe. Then, the U-shaped plate 6 is slidably installed on the outside of the fixing plate 5, so that the steel pipe is located at the lower end of the fixing plate 5. When the hydraulic rod 3 moves downward, it drives the steel pipe into the pickling tank 2, facilitating the pickling process. After completion, the hydraulic rod 3 is reset, and the U-shaped plate 6 is removed to remove all the steel pipes.
