Description

Technical Field

[0001] The utility model relates to the technical field of pickling of cold-rolled seamless steel pipes, and specifically relates to a pickling mechanism for cold-rolled seamless steel pipes. Background Art

[0002] The pickling and passivation of seamless steel pipes is a chemical reaction. First, the pickling solution can remove the scale and rust on the surface of steel, and at the same time complete the passivation process. It can effectively prevent the oxidation of seamless steel pipes and achieve the purpose of anti-corrosion. Before pickling and passivating seamless steel pipes, it is necessary to remove oil, degrease, and remove impurities such as surface drawing compounds. After pickling and passivating, the surface of the seamless steel pipe becomes uniformly silver-white, greatly improving the corrosion resistance of stainless steel.

[0003] The existing pickling method for cold-rolled seamless steel pipes is to put the steel pipes into a cleaning pool filled with pickling solution through a crane for soaking, and then lift them out and move to the next step after a period of time. When lifting the steel pipes, pickling solution will remain inside the steel pipes. As the steel pipes move, the cleaning solution will drip everywhere, causing waste of pickling solution. It may also enter the next process with the steel pipes, affecting the next process. At the same time, it is difficult to fully pickle the steel pipes only through soaking. Therefore, through technological innovation and design optimization, it is necessary to optimize a pickling mechanism for cold-rolled seamless steel pipes. Summary of the Utility Model

[0004] The existing pickling method for cold-rolled seamless steel pipes is to put the steel pipes into a cleaning pool filled with pickling solution through a crane for soaking, and then lift them out and move to the next step after a period of time. When lifting the steel pipes, pickling solution will remain inside the steel pipes. As the steel pipes move, the cleaning solution will drip everywhere, causing waste of pickling solution. It may also enter the next process with the steel pipes, affecting the next process. At the same time, it is difficult to fully pickle the steel pipes only through soaking. To solve the above problems, the embodiment of the present application provides a pickling mechanism for cold-rolled seamless steel pipes. By setting a driving part, the sliding plate can be driven to move, so that the moving plate moves to the top of the cleaning pool. The steel pipe is placed on the second filter plate, and the pickling solution inside the steel pipe can be drained, so that the pickling solution inside the steel pipe falls back into the cleaning pool again, avoiding waste of pickling solution and preventing pickling solution from remaining inside the steel pipe and entering the next step. It also avoids the pickling solution from dripping everywhere as the steel pipe moves. By setting a water pump and a pipeline, the flow rate of the pickling solution inside the cleaning pool is accelerated, facilitating more thorough cleaning of the steel pipes.

The water outlet end of the water pump is connected to the pipeline, and the water inlet end of the water pump is located inside the cleaning pool. The water pump sucks the pickling solution in the cleaning pool and then sprays it out from the round holes of the pipeline to accelerate the flow rate of the pickling solution inside the cleaning pool, facilitating more thorough cleaning of the steel pipes.

[0012] In a possible implementation manner, a rectangular opening is formed on the sliding plate, and a second filter plate is fixed inside the rectangular opening. The second filter plate is inclined. Placing the steel pipe on the inclined second filter plate can drain the pickling solution inside the steel pipe.

[0013] In a possible implementation manner, a drain port is formed on the side wall of the cleaning pool, and the drain port is close to the bottom of the cleaning cylinder, facilitating the discharge of the pickling solution.

[0014] In a possible implementation manner, blocks are fixed at the four corners of the cleaning pool, which can block the sliding plate and prevent the sliding plate from sliding off the cleaning pool.

[0015] In a possible implementation manner, sliding grooves are formed on both sides of the top of the cleaning pool, sliding blocks are arranged in the sliding grooves, and the top of the sliding blocks is fixedly connected to the bottom of the sliding plate.

All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0024] This embodiment introduces the specific structure of a pickling mechanism for cold-rolled seamless steel pipes, specifically referring to Figures 1 - 3 as shown, a pickling mechanism for cold-rolled seamless steel pipes includes:

[0025] a pool body;

[0026] a sliding plate 4, the sliding plate 4 is arranged on the top of the pool body, and a driving part capable of driving the sliding plate 4 to move is arranged between the pool body and the sliding plate 4.

[0027] Among them, the pool body includes a cleaning pool 1, baffles 13 are fixed on both sides inside the cleaning pool 1, and a first filter plate 9 on which the steel pipe can be placed is placed on the top of the baffle 13.

[0028] When it is necessary to move the sliding plate 4, the driving part includes a toothed plate 6 fixed to one side of the bottom of the sliding plate 4. A gear 12 is rotatably arranged on one side of the cleaning tank 1. A U-shaped plate 11 is fixed on the cleaning tank 1. A motor 7 capable of driving the gear 12 to rotate is installed on the U-shaped plate 11. The output end of the motor 7 penetrates through the U-shaped plate 11 and is rotatably connected to the gear 12. The motor 7 drives the gear 12 to rotate, the gear 12 drives the toothed plate 6 to move, and the toothed plate 6 drives the sliding plate 4 to move.

[0029] When the steel pipe is placed on the first filter plate 9, a pipeline 14 is arranged inside the cleaning tank 1. One end of the pipeline 14 is provided with a water pump 16, and the other end of the pipeline 14 is in a closed state. A number of round holes 15 are opened on the pipeline 14. The water outlet end of the water pump 16 is connected to the pipeline 14, and the water inlet end of the water pump 16 is located inside the cleaning tank 1. The water pump 16 sucks the pickling solution in the cleaning tank 1 and then sprays it out from the round holes 15 of the pipeline 14, accelerating the flow rate of the pickling solution inside the cleaning tank 1 and facilitating more thorough cleaning of the steel pipe.

[0030] When the steel pipe is taken out of the cleaning tank 1 and placed on the second filter plate 5, a rectangular opening 17 is formed on the sliding plate 4. The second filter plate 5 is fixed inside the rectangular opening 17. The second filter plate 5 is inclined. Placing the steel pipe on the inclined second filter plate 5 can drain the pickling solution inside the steel pipe.

[0031] When the cleaning work is completed, a drain port 8 is opened on the side wall of the cleaning tank 1. The drain port 8 is close to the bottom of the cleaning tank, facilitating the discharge of the pickling solution.

[0032] In addition, stoppers 2 are fixed at the four corners of the cleaning tank 1, which can block the sliding plate 4 to prevent the sliding plate 4 from slipping off the cleaning tank 1.

[0034] When the staff needs to pickle the steel pipe, the steel pipe is placed into the cleaning tank 1 already filled with pickling solution. The steel pipe is placed on the first filter plate 9. The water pump 16 is turned on. The water pump 16 conveys the pickling solution in the cleaning tank 1 into the pipeline 14 and then sprays it out from the round holes 15, accelerating the flow rate of the pickling solution inside the cleaning tank 1 and facilitating more thorough cleaning of the steel pipe. When the pickling is completed, the steel pipe is lifted, the motor 7 is turned on. The motor 7 drives the gear 12 to rotate, the gear 12 drives the toothed plate 6 to move, the toothed plate 6 drives the sliding plate 4 to move, and then the steel pipe is placed on the second filter plate 5, which can drain the pickling solution inside the steel pipe, making the pickling solution inside the steel pipe fall back into the cleaning tank 1 again, avoiding waste of the pickling solution, preventing the pickling solution from remaining inside the steel pipe and entering the next step, and also preventing the pickling solution from dripping everywhere when the steel pipe moves.
