[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in this embodiment, a pickling device for strip steel processing includes a pickling machine 1, a water pump 2 is fixedly connected to the top of the pickling machine 1, a connecting pipe 3 is connected to the top of the pickling machine 1, an adjusting structure 4 is provided on the front of the pickling machine 1, a pickling tank 5 is provided in the pickling machine 1, a protective plate 6 is connected in the pickling machine 1, sleeve plates 11 are connected on both sides of the protective plate 6, an auxiliary structure 7 is connected in the pickling machine 1, the protective plate 6 is clamped in the auxiliary structure 7, the auxiliary structure 7 is connected to the pickling tank 5, and the sleeve plate 11 is clamped to the adjusting structure 4;

[0022] The adjusting structure 4 includes a threaded rod 1 401, a threaded rod 2 402, a motor 404 and a transparent plate 405. Both sides of the transparent plate 405 are connected with L-shaped plates 406. The outer surface of the threaded rod 1 401 is transmission-connected with an anti-slip belt 403. The L-shaped plate 406 is clamped in the sleeve plate 11. The output shaft of the motor 404 is connected to the threaded rod 1 401, and the motor 404 drives the threaded rod 1 401 to rotate forward and reverse.

[0023] like Figure 1 and Figure 2 As shown, a liquid outlet pipe 10 is connected to the left side of the pickling machine 1, a liquid inlet pipe 9 is connected to the right side of the pickling machine 1, a water pump 2 is connected to the pickling machine 1 through a connecting pipe 3, a controller 8 is provided on the front of the pickling machine 1, a protective plate 6 is clamped in the pickling machine 1, a threaded rod 1 401 is rotatably connected to the front of the pickling machine 1, a threaded rod 2 402 is rotatably connected to the front of the pickling machine 1, a transparent plate 405 is threadedly connected to the outside of the threaded rod 1 401, the transparent plate 405 is threadedly connected to the outside of the threaded rod 2 402, and the threaded rod 1 401 is connected to the threaded rod 2 402 through an anti-slip belt 403.

[0024] By setting the anti-slip belt 403, L-shaped plate 406 and sleeve plate 11, the motor 404 drives the first threaded rod 401 to rotate. Since the first threaded rod 401 is connected to the second threaded rod 402 through the anti-slip belt 403, the first threaded rod 401 and the second threaded rod 402 will rotate synchronously, enabling the transparent plate 405 to move uniformly on the surfaces of the first threaded rod 401 and the second threaded rod 402, avoiding the phenomenon of the transparent plate 405 getting stuck during movement. And after the transparent plate 405 moves, the L-shaped plate 406 will be clamped into the sleeve plate 11, enabling the L-shaped plate 406 and the sleeve plate 11 to play a certain supporting role in the position of the protection plate 6, avoiding the phenomenon of the protection plate 6 loosening due to external force.

[0025] As Figure 3 shown, the auxiliary structure 7 includes two mounting plates 701 and two concave plates 702. The two concave plates 702 are fixedly connected to both sides inside the pickling machine 1, the two mounting plates 701 are fixedly connected to both sides of the pickling tank 5, and a clamping groove 703 is fixedly connected under each of the two mounting plates 701.

[0026] By setting the protection plate 6 and the auxiliary structure 7, the pickling tank 5 is lapped inside the pickling machine 1 through the mounting plate 701, and the clamping groove 703 under the mounting plate 701 will be clamped in the concave plate 702, enabling the pickling tank 5 to be stably lapped inside the pickling machine 1, thus playing a certain limiting role in the position of the pickling tank 5. When the protection plate 6 is clamped into the pickling machine 1, it will be clamped with the mounting plate 701 below, enabling the protection plate 6 to play a certain auxiliary role in fixing the pickling tank 5 and ensuring the stability of the pickling tank 5 after being fixed.

[0027] The present utility model provides a pickling device for strip steel processing, and the specific working principle is as follows:

[0028] When the pickling device pickles the strip steel, the strip steel can be placed into the pickling tank 5. The pickling tank 5 is lapped inside the pickling machine 1 through the mounting plate 701, and the clamping groove 703 under the mounting plate 701 will be clamped in the concave plate 702, enabling the pickling tank 5 to be stably lapped inside the pickling machine 1. Since the protection plate 6 is concave-shaped, when the protection plate 6 is clamped into the pickling machine 1, it will be clamped with the mounting plate 701 below. When the protection plate 6 is completely fitted with the pickling machine 1, the motor 404 drives the first threaded rod 401 to rotate. Since the first threaded rod 401 is connected to the second threaded rod 402 through the anti-slip belt 403, the first threaded rod 401 and the second threaded rod 402 will rotate synchronously, and the transparent plate 405 will move synchronously on the surfaces of the first threaded rod 401 and the second threaded rod 402. When the transparent plate 405 moves, it will seal the front of the pickling machine 1, and the L-shaped plate 406 will be clamped into the sleeve plate 11;

[0029] When pickling the strip steel in the pickling tank 5, the external acid liquid tank is conveyed to the bottom of the pickling machine 1 through the liquid inlet pipe 9, the acid liquid at the bottom is poured into the pickling tank 5 through the water pump 2 and the connecting pipe 3, the temperature of the acid liquid in the pickling tank 5 is controlled by the controller 8, and when the pickling is completed, the acid liquid in the area of the pickling tank 5 is discharged through the liquid outlet pipe 10, and then the acid liquid is recycled and treated.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
