Description

Technical Field

[0001] This utility model relates to the field of pickling technology, specifically to an environmentally friendly and efficient pickling device. Background Technology

[0002] Currently, batch pickling of workpieces typically involves suspended pickling in enclosed rooms using room-temperature hydrochloric acid. This method is time-consuming and slow, especially in winter, making it difficult to meet production capacity requirements. Pickling generally takes 20-60 minutes and requires large, enclosed rooms to seal all the acid tanks, resulting in high overall costs. Therefore, current room-temperature pickling methods suffer from problems such as slow pickling speed, incomplete pickling, numerous acid tanks, large floor space requirements, high costs for acid mist collection and treatment, and significant environmental pollution.

[0003] Therefore, an environmentally friendly and efficient pickling device is proposed. Summary of the Invention

[0006] The pickling tank is equipped with a movable sealing cover on top, and a condenser tube is installed on the inside of the sealing cover. A heater for heating the pickling solution is installed on the pickling tank.

[0007] Preferably, the lower surface of the sealing cover is equipped with multiple casters.

[0008] Preferably, racks are installed on both sides of the sealing cover, motors are installed on both sides of the pickling tank, and gears that are compatible with the racks are installed on the output shaft of the motors.

[0009] Preferably, a sealing airbag is installed on the lower surface of the sealing cover.

[0010] Preferably, the cover is equipped with a suction pipe for extracting water vapor and acid mist.

[0011] Preferably, the heater is heated by steam or by electricity.

[0012] Preferably, the pickling tank is equipped with a support frame on the inner side to facilitate the placement of workpieces.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by using high-temperature pickling, pickling efficiency is improved, pickling time is shortened, the number of acid tanks is greatly reduced, the enclosed room covering the entire acid tank is eliminated, the floor space is reduced, and through condensation and the cover, water vapor and acid mist can be collected and reused more effectively.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an environmentally friendly and efficient pickling device, including a pickling tank 4, with supports 1 on both sides of the pickling tank 4, a mobile trolley 2 installed on the supports 1, a cover 3 installed below the mobile trolley 2, an electric hoist 5 installed below the mobile trolley 2, and an electric gripper for gripping workpieces installed on the lifting end of the electric hoist 5, the electric gripper being located inside the cover 3.

[0021] The top of the pickling tank 4 is equipped with a movable sealing cover 6, and a condenser pipe 11 is installed inside the sealing cover 6. A heater 14 for heating the pickling solution is installed on the pickling tank 4.

[0022] like Figure 2 and Figure 4 As shown: Multiple moving wheels 10 are installed on the lower surface of the sealing cover 6, and racks 12 are installed on both sides of the sealing cover 6. Motors 7 are installed on both sides of the pickling tank 4, and gears that are compatible with the racks 12 are installed on the output shaft of the motors 7. With the above settings, the motors 7 drive the gears to rotate, and the gears and racks 12 cooperate with each other to make the sealing cover 6 move left and right, thereby completing the opening and closing of the sealing cover 6.

[0023] like Figure 4 As shown: A sealing airbag 13 is installed on the lower surface of the sealing cover 6; through the above settings, the sealing work can be completed by the cooperation of the sealing airbag 13 with the upper surface of the pickling tank 4, thus avoiding the spread of acid mist.

[0024] like Figure 3 As shown: The cover 3 is equipped with a suction pipe 9 for extracting water vapor and acid mist; with the above settings, the cover 3 with the workpiece is moved above the pickling tank 4, and when the sealing cover 6 is opened, the suction pipe 9 can extract a small amount of water vapor and acid mist that evaporates when it is opened.

[0025] like Figure 2 As shown: Heater 14 uses steam heating or electric heating; through the above settings, the pickling liquid inside the pickling tank 4 can be heated, thereby accelerating the pickling process and improving the overall work efficiency.

[0026] like Figure 2 As shown: A support frame 8 is installed on the inner side of the pickling tank 4 to facilitate the placement of workpieces; through the above settings, the workpieces placed inside the pickling tank 4 can be supported, which facilitates subsequent hoisting work.

[0027] Working principle: The mobile crane 2 moves the cover 3 to lift the workpiece from the loading station by the electric hoist 5 and electric gripper, and moves it to the top of the pickling tank 4. Then, the sealing cover 6 at the top of the pickling tank 4 is opened by the motor 7, gear and rack 12. When it is opened, a small amount of water vapor and acid mist is extracted by the suction pipe 9. After the sealing cover 6 is opened, the workpiece is put into the interior of the pickling tank 4. After the electric gripper moves out, the sealing cover 6 is closed and sealed by the sealing airbag 13.

[0028] During the pickling process, the pickling solution can be heated by the heater 14 on the pickling tank 4, thereby accelerating the pickling process. At the same time, the acid mist and water vapor generated during the heating process can be condensed by the condenser 11 on the sealing cover 6, so that the acid mist and water vapor can flow back into the interior of the pickling tank 4.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
