Description

Technical Field

[0001] The utility model relates to the technical field of metal surface treatment, in particular to a pickling device for hot-dip galvanizing process. Background Technique

[0002] The hot-dip galvanizing process is a widely used metal surface treatment technology. It infiltrates zinc or zinc alloy into the surface of the base metal by means of heating and diffusion to form an alloy layer, thereby enhancing the corrosion resistance of the metal and extending its service life.

[0003] When the metal is subjected to the hot-dip galvanizing process, pickling treatment is required. By placing the workpiece in a pickling device and using pickling solution to remove the oxide layer and rust on the surface, the quality and adhesion of the subsequent galvanized layer can be improved.

[0004] At present, during the pickling process of the workpiece, the reaction between the acidic solution and the metal surface will generate acid mist. The generated acid mist will cause harm to the environment and the health of workers. Therefore, pickling devices are all provided with a closed space. By performing pickling in the closed space, the spillage of acid mist can be effectively controlled and the pollution of the working environment can be reduced. However, the existing pickling devices have poor sealing performance. When workers send the workpiece into the pickling device for pickling, they will inhale the acid mist, which will cause harm to the health of workers in the long run. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the existing pickling device mentioned in the above background technique has poor sealing performance. When workers send the workpiece into the pickling device for pickling, they will inhale the acid mist, which will cause harm to the health of workers in the long run.

[0031] Please refer to Figures 1-6 , a pickling device for hot-dip galvanizing process, which includes an enclosed box 1. A pickling tank 5 is arranged inside the enclosed box 1. A first closing door 3 and a second closing door 4 are arranged at the inlet of the enclosed box 1. A parking room for placing workpieces to be pickled is formed between the first closing door 3 and the second closing door 4. A loading and unloading part 2 for picking up and placing pickled workpieces is arranged inside the enclosed box 1.

[0032] Further, the first closing door 3 is close to the outside of the closed box 1, and the second closing door 4 is close to the inside of the closed box 1. Suction frames 11 are symmetrically arranged inside the closed box 1. The suction frames 11 are close to the second closing door 4. A first suction hood 12 communicated with the suction frames 11 is arranged outside the suction frames 11. Double sealing is achieved through the first closing door 3 and the second closing door 4, which can prevent acid mist from leaking during the pickling process of metal workpieces. Both the first closing door 3 and the second closing door 4 are rolling doors with good sealing performance during use. Sealing plates corresponding to them are arranged on both sides of the first closing door 3 and the second closing door 4, so that both sides of the rolling curtains of the first closing door 3 and the second closing door 4 are in the sealing plates. A second suction hood 13 is arranged on the closed box 1. The second suction hood 13 corresponds to the parking room. Both the first suction hood 12 and the second suction hood 13 are externally connected to a fan through pipes respectively, and the discharge end of the fan is connected to an acid mist treatment device through a pipe. After the second closing door 4 is opened, the acid mist will float towards the parking room. The acid mist floating towards the parking room can be sucked away by the first suction hood 12, so that the acid mist entering the parking room can be reduced. Even when a small amount of acid mist drifts into the parking room, the second suction hood 13 can further suck away the entering acid mist, which can prevent acid mist from floating out when the worker moves the cart 6 into or out of the parking room. And through effective removal of the acid mist, it can prevent the worker from inhaling the acid mist.

[0033] Furthermore, the pick-and-place part 2 includes a fixed frame 21. A first linear motor 22 is longitudinally arranged on the fixed frame 21. A moving plate 27 is arranged on the moving component of the first linear motor 22. A second linear motor 23 is vertically arranged on the moving plate 27. A connecting plate 24 is arranged on the moving component of the second linear motor 23. A pick-up plate 25 is arranged at one end of the connecting plate 24 away from the second linear motor 23. The pick-and-place part 2 is used to pick up, place and move the material placing frame 61 in the parking room.

[0034] A cart 6 is parked in the parking room. A material placing frame 61 is placed in the cart 6. Fixing plates 611 are symmetrically arranged on the material placing frame 61. A connecting rod 612 is arranged between the two fixing plates 611. The workpieces to be pickled can be placed through the material placing frame 61. The material placing frame 61 is placed in the cart 6, which is convenient for the worker to move the material placing frame 61 into the parking room. A pick-up groove 26 is arranged on the pick-up plate 25, so that the connecting rod 612 on the material placing frame 61 can be better hung on the pick-up plate 25 through the pick-up groove 26.

[0035] It should be noted that two positioning members 7 are provided inside the closed box 1. The two positioning members 7 are symmetrically arranged on both sides of the trolley 6. The positioning member 7 includes a positioning plate 71. A groove 72 is provided on the positioning plate 71. An elastic plate 73 is provided inside the groove 72. An elastic end 731 is provided on the elastic plate 73. The positioning member 7 facilitates the worker to quickly position the trolley 6, and when the picking and placing member 2 takes out the loading frame 61, it can be stably taken out. Positioning grooves 62 that can cooperate with the elastic ends 731 are symmetrically provided on the trolley 6. The two elastic ends 731 abut against the positioning grooves 62, which can better position the trolley 6.

[0036] It should be added that a push handle is provided on the trolley 6. Inclined surfaces 63 are symmetrically provided on both sides of the side of the trolley 6 away from the push handle. Through the inclined surfaces 63, the trolley 6 can be better moved between the two positioning plates 71, and the inclined surfaces 63 can better push the elastic ends 731 to deform.

[0037] When the utility model is in use, an acidic solution is contained in the pickling tank 5. The worker can place the workpiece to be pickled into the loading frame 61 inside the trolley 6, and then open the first closing door 3, push the trolley 6 into the parking room. The trolley 6 moves between the two positioning members 7. The inclined surfaces 63 of the trolley 6 squeeze the elastic ends 731 on the elastic plate 73 inward, causing them to deform. Until the trolley 6 moves to a position where the positioning groove 62 corresponds to the elastic ends 731, the elastic ends 731 reset to clamp and position the trolley 6. Then the worker pushes it out of the parking room. After the first closing door 3 is closed, the second closing door 4 is opened and the fans connected to the first suction hood 12 and the second suction hood 13 are started. After the second closing door 4 is opened, the acid mist will float towards the parking room. The first suction hood 12 can suck away the acid mist floating towards the parking room, thereby reducing the acid mist that can enter the parking room. Even when a small amount of acid mist drifts into the parking room, the second suction hood 13 can further suck away the entering acid mist. At this time, the first linear motor 22 is started to drive the second linear motor 23 and the picking plate 25 to move towards the trolley 6, and the picking plate 25 can be moved into the parking room, and the picking groove 26 is located above the connecting rod 612. Then the second linear motor 23 is started to move upward. The connecting plate 24 drives the picking plate 25 to move upward. The picking plate 25 moves the connecting rod 612 upward through the picking groove 26, thereby lifting the loading frame 61 and moving the loading frame 61 out of the trolley 6. Then the first linear motor 22 is started again to drive the second linear motor 23 to move back, so that the loading frame 61 moves above the pickling tank 5. The second linear motor 23 is started again to put the loading frame 61 into the pickling tank 5 through the picking plate 25 for pickling treatment. During the pickling treatment, the second closing door 4 is in a closed state, which can effectively prevent the acid mist from pickling from overflowing, and through the transition of the parking room, it can effectively prevent the acid mist from overflowing, and can more effectively protect the worker, so that the worker will not inhale the acid mist when pickling the workpiece, and can better protect the health of the worker.

The object of the present utility model has been fully and effectively achieved. The functions and structural principles of the present utility model have been demonstrated and explained in the embodiments, and without departing from the said principles, any deformation or modification can be made to the embodiments of the present utility model.
