DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: comprising a pickling box 1, a pickling pool 2 is provided in the pickling box 1, a drying pool 3 is provided in the pickling box 1, a drying component is provided in the drying pool 3, and the drying component comprises a ventilation component and a cleaning component.

[0023] The cleaning components include a nozzle 7, and two nozzles 7 are respectively installed on the left and right sides of the inner wall of the control tank 3. A water pipe is arranged on the top of the two nozzles 7. The other ends of the two water pipes are respectively connected to a neutralizing liquid tank and a clean water tank. The solution in the neutralizing liquid tank can be selected as sodium carbonate or sodium hydroxide solution, etc. A drain pipe 102 is arranged on the left side of the pickling tank 1. The drain pipe 102 is connected to the bottom surface of the control tank 3. The bottom surface of the control tank 3 is inclined, and the lowest end of the bottom surface of the control tank 3 is the connection point between the control tank 3 and the drain pipe 102.

[0024] By adopting the above design, when the seamless steel pipe completes pickling in the pickling tank 2 and enters the drying tank 3 for drying, the two nozzles 7 can be started to spray the neutralizer and clean water on the seamless steel pipe from both sides of the seamless steel pipe. The neutralizer neutralizes the acid solution remaining after pickling, and then the mixed solution is washed away together with clean water, thereby preventing the seamless steel pipe from being directly dried after pickling, and the acid solution with poor volatility will remain on the surface of the seamless steel pipe to form acid stains, causing corrosion to the surface of the seamless steel pipe.

[0025] In this process, impurities mixed with the acid can be flushed down together, thereby cleaning the seamless steel pipe and further improving the cleanliness of the seamless steel pipe after pickling.

[0026] Furthermore, through the inclined design of the drain pipe 102 and the drain tank 3 , a mixture of liquids such as clean water, acid residue, and neutralizing liquid can be quickly discharged from the drain tank 3 .

[0027] refer to Figure 1 and Figure 2 Furthermore, the ventilation component includes an exhaust fan 8. A vent 101 connected to the dry control pool 3 is opened in the pickling box 1. A horizontal plate is installed in the vent 101, and the exhaust fan 8 is installed on the horizontal plate. Ventilation holes 101 are opened on the front and back sides of the pickling box 1. There are two exhaust fans 8, which are fixedly connected to the horizontal plates of the two vents 101 respectively, and the wind directions of the two exhaust fans 8 are opposite.

[0028] Because ventilation holes 101 connected to the drying tank 3 are provided on the front and rear sides of the pickling box 1, a horizontal plate is installed on each ventilation hole 101, and an exhaust fan 8 is fixedly connected to the horizontal plate. Through the convection effect of the exhaust fan 8, the air flow speed in the drying tank 3 can be increased, thereby accelerating the evaporation of moisture on the surface of the steel pipe and shortening the drying time. Moreover, since the wind directions of the two exhaust fans 8 are opposite, the convection formed by them in the drying tank 3 can ensure that the air flows evenly in the tank, so that all parts of the steel pipe can obtain a uniform drying effect, avoiding the phenomenon of partial undrying or uneven drying.

[0029] Furthermore, refer to Figure 1-3 , also includes a moving component, the moving component includes a moving frame 4, the moving frame 4 is located above the pickling box 1, a moving groove 401 is opened in the moving frame 4, a connecting groove 402 is opened on the bottom surface of the moving groove 401, a motor 5 is fixedly connected to one side of the moving frame 4, the output shaft of the motor 5 is fixedly connected to a threaded rod 501, the threaded rod 501 is threadedly connected to the moving block 6, the moving groove 401 is slidably connected to the moving block 6, the bottom surface of the moving block 6 passes through the connecting groove 402, and the bottom surface of the moving block 6 is connected to a placement component.

[0030] The side of the mobile frame 4 is fixedly connected with a mounting bracket 403 . There are four mounting brackets 403 , which are symmetrically arranged on both sides of the front and back of the mobile frame 4 . The other end of the mounting bracket 403 is fixedly connected to the pickling box 1 .

[0031] The placement assembly includes a placement rack 602, a lifting rod 601 is fixedly connected at the center of the top surface of the placement rack 602, the other end of the lifting rod 601 is fixedly connected to the bottom surface of the moving block 6, and four support plates are arranged on the placement rack 602, and the ends of the support plates are fixedly connected to the limiting columns 603.

[0032] When pickling is performed, the motor 5 can be started to drive the threaded rod 501 to rotate. Since there is a threaded connection between the threaded rod 501 and the moving block 6, the moving block 6 slides horizontally along the moving groove 401 under the rotation of the threaded rod 501. The bottom surface of the moving block 6 is connected to the placement component through the connecting groove 402, thereby driving the placement component and the seamless steel pipe thereon to move together, thereby realizing the horizontal movement of the seamless steel pipe.

[0033] The placement component includes a placement rack 602, which is fixedly connected to the bottom surface of the moving block 6 through a lifting rod 601. The lifting rod 601 can be extended and retracted as needed to adjust the height of the placement rack 602. Driven by the lifting rod 601, the placement rack 602 and the seamless steel pipe thereon can be lifted and lowered in the vertical direction.

[0034] During the lifting and moving process, in order to prevent the seamless steel pipe from falling, four support plates are set on the placement frame 602, and limiting columns 603 for fixing and supporting the seamless steel pipe are set at the end of the support plate. The limiting columns 603 can ensure that the seamless steel pipe remains stable during the movement and lifting process to prevent it from shaking or falling off.

[0035] By adopting the above design, the automatic movement and lifting of the seamless steel pipe in the pickling box 1 are realized, the automation level of the pickling process is improved, and the difficulty and error rate of manual operation are reduced. At the same time, the automatic movement and lifting can quickly move the seamless steel pipe from the pickling tank 2 to the drying tank 3, shortening the processing time and improving the overall work efficiency. In addition, the automated operation reduces the safety hazards in manual operation and improves the safety of the operation process.

[0036] In addition, reference Figure 2 and Figure 4 The bottom surface of the pickling tank 2 is provided with a lifting pad 201, and the lifting pad 201 has eight pieces, two pieces in a group and four groups. The lifting pads 201 in each group are symmetrically arranged on both sides of the placement rack 602, and the four groups of lifting pads 201 are arranged in a circular array with equal intervals.

[0037] By providing the lifting pad 201, the bottom side of the seamless steel pipe will be lifted up during pickling, so that the bottom surface in contact with the placement rack 602 can also be in contact with the acid solution, thereby making the pickling of the seamless steel pipe more thorough.

[0038] Working principle:

[0039] When pickling is performed, the motor 5 can be started to drive the threaded rod 501 to rotate. Since there is a threaded connection between the threaded rod 501 and the moving block 6, the moving block 6 slides horizontally along the moving groove 401 under the rotation of the threaded rod 501. The bottom surface of the moving block 6 is connected to the placement component through the connecting groove 402, thereby driving the placement component and the seamless steel pipe thereon to move together, thereby realizing the horizontal movement of the seamless steel pipe.

[0040] The placement component includes a placement rack 602, which is fixedly connected to the bottom surface of the moving block 6 through a lifting rod 601. The lifting rod 601 can be extended and retracted as needed to adjust the height of the placement rack 602. Driven by the lifting rod 601, the placement rack 602 and the seamless steel pipe thereon can be lifted and lowered in the vertical direction.

[0041] During the lifting and moving process, in order to prevent the seamless steel pipe from falling, four support plates are set on the placement frame 602, and limiting columns 603 for fixing and supporting the seamless steel pipe are set at the end of the support plate. The limiting columns 603 can ensure that the seamless steel pipe remains stable during the movement and lifting process to prevent it from shaking or falling off.

[0042] When the seamless steel pipe completes pickling in the pickling tank 2 and enters the drying tank 3 for drying, the two nozzles 7 can be started to spray the neutralizer and clean water on the seamless steel pipe from both sides of the seamless steel pipe. The neutralizer can neutralize the acid solution remaining after pickling, and then the mixed solution can be washed away together with clean water, thereby preventing the acid solution from being directly dried after pickling, and the acid solution with poor volatility will remain on the surface of the seamless steel pipe to form acid stains, causing corrosion to the surface of the seamless steel pipe.

[0043] During the drying process, the two exhaust fans 8 with opposite wind directions can be started to increase the air flow rate in the drying pool 3, thereby accelerating the evaporation of moisture on the surface of the steel pipe and shortening the drying time. Moreover, since the wind directions of the two exhaust fans 8 are opposite, the convection formed by them in the drying pool 3 can ensure that the air flows evenly in the pool, so that all parts of the steel pipe can obtain a uniform drying effect, avoiding the phenomenon of partial undried or uneven drying.
