[0002] In modern manufacturing, seamless steel pipes have become important materials in many industrial processes due to their superior mechanical properties and wide range of applications. However, during the production of seamless steel pipes, an oxide layer or other impurities often form on the surface of the steel pipes. These impurities will affect their subsequent processing and performance, thus requiring pickling treatment.

[0003] In the existing patent: CN201710962743-A pickling tank and a method for processing seamless steel pipes using the pickling tank, a tank body is included, and the key points of the technical solution are that the tank body is provided with several auxiliary devices for fixing seamless steel pipes, and the auxiliary devices include a base, a column and a fixing member, the base is fixedly connected to the bottom wall of the tank body, the column is fixedly connected to the base, and the fixing member is rotatably connected to the column; the outer wall of the column is provided with several cleaning members. The purpose of reducing the oxide scale adhered to the surface of the seamless steel pipe is achieved.

[0004] Although the above pickling tanks can remove the oxide layer on the surface of steel pipes to a certain extent, they still have the following major problems:

At the same time, the pickling solution in the processing tank 1 is fully stirred by the pickling auxiliary turbulence driving component to improve the internal circulation effect of the pickling solution and further enhance the pickling effect.

[0048] Example 2

[0049] Based on Example 1, please refer to Figure 3-4 The seamless steel pipe conveying device 3 includes: a bearing bracket 12, two groups of bearing brackets 12 are symmetrically installed on the outer wall of the processing pool 1, a driving motor 13 is fixedly installed on the bearing bracket 12 on the left, one end of the threaded rod 14 on the left is fixedly connected to the fixed end of the driving motor 13, the other end of the threaded rod 14 on the left is rotatably connected to the bearing bracket 12 on the left, and both ends of the threaded rod 14 on the right are respectively rotatably connected to the bearing bracket 12 on the right, and the outer walls of the two groups of threaded rods 14 are fixedly sleeved with the same pulley 16, and the two groups of pulleys 16 are connected by a belt 17.

[0051] The seamless steel pipe fastening device 23 includes: a guide sleeve 24, which is fixedly connected to the inner wall of the U-shaped groove of the U-shaped bracket 4, a push plate 26 movably arranged in the U-shaped groove of the U-shaped bracket 4, and an electromagnet 31 is fixedly connected to the push plate 26, a permanent magnet 29 is fixedly connected to the inner wall of the U-shaped groove of the U-shaped bracket 4, and the electromagnet 31 and the permanent magnet 29 are located on the same axis, two ends of a reset spring 30 are respectively fixedly connected to the electromagnet 31 and the permanent magnet 29, a steel pipe claw 28 is fixedly provided at one end of a first connecting rod 27, and the other end of the first connecting rod 27 is movably extended into the U-shaped groove of the U-shaped bracket 4 and is fixedly connected to the push plate 26.

[0052] The working principle and beneficial effects of the above technical solution are as follows: when in use, after the electromagnet 31 is energized, the permanent magnet 29 attracts the electromagnet 31 to move in the direction close to the permanent magnet 29, thereby driving the first connecting rod 27 to retract into the guide sleeve 24 through the push plate 26, and the return spring 30 is compressed to accumulate kinetic potential energy. At this time, after the seamless steel pipe 25 is placed between several groups of seamless steel pipe fastening devices 23 in the U-shaped bracket 4, the electromagnet 31 is powered off, and the return spring 30 is reset while pushing the first connecting rod 27 to move in the direction close to the seamless steel pipe 25 through the push plate 26 until several groups of steel pipe claws 28 clamp the seamless steel pipe 25, and the return spring 30 has not reached the natural length, and can continuously provide pressure to the seamless steel pipe 25, thereby preventing the seamless steel pipe 25 from falling off.

[0053] Example 3

[0054] Based on any one of Examples 1-2, please refer to Figure 5-8 The pickling auxiliary spoiler drive assembly includes: an H-shaped bracket 34, the H-shaped bracket 34 is fixedly arranged on the top of the auxiliary pool 5, the driving motor three 32 is fixedly connected to the H-shaped bracket 34, the driving motor three 32 has a driving disk 33 fixedly sleeved on the output shaft, and the driving disk 33 is fixedly provided with a limiting column 38 on the side away from the driving motor three 32, the bearing seat 35 is installed on the top of the auxiliary pool 5, and the bearing seat 35 is located below the H-shaped bracket 34, the rotating shaft 59 is movably connected to the bearing seat 35, and the bearing seats 35 are extended from both ends of the rotating shaft 59, one end of the rotating shaft 59 is fixedly provided with a fan-shaped toothed piece 36, and the other end of the rotating shaft 59 is fixedly sleeved with a pulley two 56.

[0055] Preferably, the fan-shaped tooth part 36 extends toward one end away from its tooth groove to form a guide groove 37, and the limit column 38 is movably arranged in the guide groove 37, the fixed block 39 is fixedly connected to the inner wall of the auxiliary pool 5, the end of the guide member 41 close to the fixed block 39 is fixedly connected to the fixed block 39, the driving rack 42 is slidably connected to the guide member 41, and the fan-shaped tooth part 36 is meshed with the driving rack 42, the top of the connecting plate 43 is fixedly connected to the driving rack 42, the U-shaped guide member 51 is fixedly connected to the bottom of the inner wall of the auxiliary pool 5, and a guide slider 52 is movably arranged in the U-shaped guide member 51, the guide slider 52 is fixedly connected to the connecting plate 43, and the heating device 44 is installed in the auxiliary pool 5.

[0056] Preferably, the piston sleeve 40 is fixedly connected to the fixed block 39, the piston block 46 is movably arranged in the piston sleeve 40, and the piston block 46 is provided with a guide hole and an electromagnetic valve 47 is installed in its guide hole, one end of the second connecting rod 48 is fixedly connected to the center of the piston block 46, the other end of the second connecting rod 48 is connected to the driving rack 42 through the fixed block 49, one end of the connecting hose 50 passes through the fixed block 39 and extends into the piston sleeve 40, the other end of the connecting hose 50 passes through the connecting plate 43 and the sliding baffle 45 and is connected to the spoiler stirring member 54, the piston sleeve 40 is connected to the spoiler stirring member 54 through the connecting hose 50, the sliding baffle 45 is fixedly connected to the connecting plate 43, the spoiler stirring member 54 is connected to the sliding baffle 45 through the fixed block 3 53, and the spoiler stirring member 54 is located in the processing pool 1 and is slidably connected to the bottom of the inner wall of the processing pool 1, and a plurality of groups of injection heads 55 are provided on the spoiler stirring member 54.

[0057] Preferably, the drive shaft 60 is movably connected to the inner wall of the auxiliary pool 5 , the pulley three 58 and the stirring blade 61 are fixedly sleeved on the outer wall of the drive shaft 60 , and the pulley three 58 is movably connected to the inner wall of the auxiliary pool 5 through the drive shaft 60 .

[0058] The working principle and beneficial effects of the above technical solution are as follows: when in use, the driving motor 32 is started to drive the driving disk 33 to rotate, so that the limit column 38 slides along the guide groove 37, and the fan-shaped tooth part 36 is driven to rotate back and forth. At this time, the fan-shaped tooth part 36 drives the driving rack 42 to slide back and forth along the guide part 41, and drives the sliding baffle 45 to move back and forth through the connecting plate 43. At this time, the sliding baffle 45 drives the turbulent stirring member 54 to slide back and forth along the bottom of the inner wall of the processing pool 1 through the fixed block 3 53, so that the pickling liquid in the processing pool 1 can be turned over at a regular time.

[0059] At the same time, when the driving rack 42 moves back and forth, it will drive the second connecting rod 48 through the fixed block 49 to slide the piston block 46 along the inner wall of the piston sleeve 40. When the piston block 46 moves outward, the pickling liquid at the bottom of the processing pool 1 will be drawn into the turbulent stirring member 54 through the injection head 55, and then drawn into the piston sleeve 40 through the connecting hose 50. When the piston block 46 moves inward, the pickling liquid drawn into the piston sleeve 40 will be pushed into the turbulent stirring member 54 along the connecting hose 50 and then sprayed out through several groups of injection heads 55, thereby forming a water flow with impact force at the bottom of the processing pool 1, and then the turbulent stirring member 54 reciprocatingly moves to form a bypass effect, thereby accelerating the internal circulation effect of the pickling liquid in the processing pool 1. When the injection head 55 is not needed to perform auxiliary injection turbulence or the injection head 55 is needed to reduce the injection pressure, it is only necessary to control the solenoid valve 47 to open.

[0060] On the basis of the above, when it is necessary to increase the concentration of the pickling liquid in the processing pool 1 or to add any required catalyst to the processing pool 1, the liquid and any catalyst can be injected into the auxiliary pool 5 through the catalyst injection funnel 6, and the fan-shaped tooth part 36 will drive the pulley 2 56 to rotate through the rotating shaft 59 when it rotates back and forth. The pulley 2 56 drives the pulley 3 58 to rotate through the belt 2 57, and the pulley 3 58 drives the stirring blade 61 to rotate through the driving shaft 60, so that the solvent put into the auxiliary pool 5 can be quickly dissolved, and when it is necessary to increase the temperature of the pickling liquid to make it work faster, the premixed solution in the auxiliary pool 5 can be heated by the heating device 44, and the stirring blade 61 can rotate synchronously while the pickling liquid in the auxiliary pool 5 and the processing pool 1 far away can circulate to the vicinity of the heating device 44, so as to achieve the effect of quickly changing the temperature.

[0061] Among them, the heating device 44 adopts electric heating, the heating wire is placed in the auxiliary pool 5, and the electric heating unit is installed on the outer wall of the auxiliary pool 5. The heating device 44 is a common mechanism on the market and will not be described in detail here. The connecting hose 50 has a sufficient length in the auxiliary pool 5 to avoid the connecting hose 50 being torn off when the connecting plate 43 moves back and forth. The size of the sliding baffle 45 can just cover the area of ​​the installation groove 7. When the sliding baffle 45 moves back and forth, the installation groove 7 can be regarded as a circulation opening and closing, so that the solution between the processing pool 1 and the auxiliary pool 5 can circulate. The belt 57 is made of a material that is not corroded by pickling. The coordinated use of the U-shaped guide 51 and the guide slider 52 can ensure the stable movement of the connecting plate 43 and prevent it from shifting.

[0062] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
