[0036] Reference Figure 2 and Figure 3 , a rotating shaft 171 is fixed to one end of both sides of the supporting plate 17 close to the partition 11, and a moving groove 172 is provided on the opposite inner side of the pickling tank 12, and the end of the rotating shaft 171 away from the supporting plate 17 is inserted into the moving groove 172. The driving mechanism 2 includes a screw rod 1 21 and a screw rod 23 rotatably mounted on both sides of the inner bottom surface of the pickling tank 12, and the screw rod 1 21 is located on the side of the screw rod 2 23 away from the partition 11.

[0038] Reference Figure 1 , Figure 2 and Figure 3Two rotating shafts 25 are provided on the opposite inner sides of the pickling tank 12, and the rotating shafts 25 are rotatably connected to the pickling box 1.

[0040] Reference Figure 1 and Figure 3 The water control assembly 4 includes two transmission rollers 41 and a plurality of support rollers 42 rotatably mounted between opposite sides of the water control tank 13. The plurality of support rollers 42 are located between the two transmission rollers 41. The outer circumference of the two support rollers 42 is wrapped with a conveyor belt 43. The outer circumference of the conveyor belt 43 is provided with a plurality of water-permeable holes 44. A motor 2 45 is fixed to the side of the pickling tank 1.

[0041] When the steel on the support plate 17 passes through the opening 18 and slides onto the conveyor belt 43, the sensor 47 detects the steel and transmits the detected signal to the controller 48. The controller 48 controls the motor 2 45 to start. The output shaft of the motor 2 45 drives one of the transmission rollers 41 to rotate, so that the transmission roller 41 drives the conveyor belt 43 to rotate, so that the conveyor belt 43 drives the steel to move in the direction away from the partition 11, thereby reducing the accumulation of steel at the end of the conveyor belt 43 close to the partition 11. Then, the electric fan 51 is started to blow air toward the steel on the conveyor belt 43, so as to facilitate the rapid drying of the solution on the surface of the steel on the conveyor belt 43.

[0042] Reference Figure 2, Figure 4 and Figure 5 , a discharge port 52 is provided on the side of the pickling box 1, and the discharge port 52 is connected to the water control tank 13. Two fixed blocks 53 are fixed on the side of the pickling box 1, and the two fixed blocks 53 are respectively located on both sides of the discharge port 52. The sides of the two fixed blocks 53 close to each other are provided with plug-in grooves 54, and the plug-in grooves 54 penetrate the top surface of the fixed block 53 and the side of the fixed block 53 close to the pickling box 1.

The notches 56 are located below the conveyor belt 43, and the two ends of the sealing plate 55 can be inserted into the two notches 56.

[0043] When the water control of the steel on the conveyor belt 43 is completed, the sealing plate 55 is pulled out from the two fixed plates 3, and then the two ends of the sealing plate 55 are respectively inserted into the two slots 56, and then the motor 312 is started, and the output shaft of the motor 312 drives the rotating roller to rotate, and the rotating roller drives the conveyor belt 43 to rotate, so that the steel on the conveyor belt 43 falls onto the sealing plate 55, so that the steel is discharged from the water control pool 13.

[0044] The implementation principle of a steel pickling device in an embodiment of the present application is as follows: when the steel needs to be pickled, the steel is placed on a support plate 17, so that the solution in the pickling tank 12 pickles the steel; when the steel is pickled, two motors 131 are started at the same time, and the output shaft of the motor 131 drives one of the rotating shafts 25 to rotate, the rotating shaft 25 drives the pulley 32 to rotate, the pulley 32 drives the transmission belt 33 to rotate, so that the transmission belt 33 drives another pulley 32 to rotate, so that the other pulley 32 drives another rotating shaft 25 to rotate, so that the two rotating shafts 25 rotate at the same time, the two rotating shafts 25 respectively drive the two bevel gears 27 to rotate, the two bevel gears 27 drive the two bevel gears 131 to rotate, and the two bevel gears 131 respectively drive the two bevel gears 132 to rotate. The movable screw rod 21 and the screw rod 23 rotate, the screw rod 21 drives the push rod 22 to move upward, the screw rod 23 drives the push rod 24 to move upward, so that the push rod 22 and the push rod 24 drive the supporting plate 17 to move upward, so that the end of the supporting plate 17 close to the partition 11 moves to the through-hole 18. Since the pitch of the screw rod 21 is greater than the pitch of the screw rod 23, when the screw rod 21 and the screw rod 23 rotate at the same time, the distance that the push rod 22 moves upward is greater than the distance that the push rod 24 moves upward, so that when the push rod 22 and the push rod 24 push the supporting plate 17 to move upward, the supporting plate 17 is in an inclined state, so that the steel on the supporting plate 17 slides along the inclined surface of the supporting plate 17 through the through-hole 18 and onto the conveyor belt 43. The sensor 47 detects the steel and transmits the signal to the controller 48. The controller 48 controls the motor 2 45 to start according to the received signal. The output shaft of the motor 2 45 drives one of the transmission rollers 41 to rotate. The transmission roller 41 drives the conveyor belt 43 to rotate, so that the conveyor belt 43 drives the steel to move away from the partition 11, so that the steel is evenly distributed on the surface of the conveyor belt 43, reducing the steel gathering at the end of the conveyor belt 43 close to the partition 11. Then, the electric fan 51 is started to blow air toward the steel on the conveyor belt 43 to quickly dry the solution on the surface of the steel. Then, the sealing plate 55 is pulled out from the two fixing plates 3, and then the two ends of the sealing plate 55 are respectively inserted into the two slots 56 to make the sealing plate 55 in an inclined state. Then, the motor 2 45 is started, and the output shaft of the motor 2 45 drives the transmission roller 41 to rotate, and the transmission roller 41 drives the conveyor belt 43 to rotate, so that the steel on the conveyor belt 43 falls onto the sealing plate 55, so that the surface of the steel is in a dry state when the steel is discharged from the water control pool 13, thereby reducing the possibility that the pickling solution is on the surface of the steel when the pickled steel is taken out, causing the pickling solution to drip on the staff and cause harm to the staff.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
