Description

Technical Field

[0001] This utility model relates to the field of metal processing, and in particular to an acid pickling tank with a partitioned waste gas collection structure. Background Technology

[0002] In the metal processing industry, pickling is a crucial step in removing oxide layers, rust, and impurities from metal surfaces. The pickling tank, as the core equipment in this process, directly impacts processing quality and operational safety. Currently, conventional pickling tanks on the market generally suffer from the following problems:

[0003] High risk of exhaust gas leakage: Traditional pickling tanks are mostly open or semi-open structures. Harmful exhaust gases such as hydrochloric acid mist and sulfuric acid mist generated during the pickling process can easily diffuse directly into the working environment, which not only endangers the health of operators but also corrodes surrounding equipment, failing to meet environmental protection and safety standards. Low workpiece processing efficiency and easy damage: Existing pickling tanks usually stack multiple workpieces directly in the tank for pickling. Workpieces are prone to collisions, resulting in surface damage. At the same time, the stacked state can cause insufficient contact between the workpieces and the pickling solution, resulting in uneven pickling, oxide layer residue, and other problems, affecting the accuracy of subsequent processing. Contradiction between pickling effect and operational convenience: Some pickling tanks adopt a fully enclosed design to improve sealing, but the enclosed structure makes it inconvenient to pick up and put down workpieces, requiring frequent opening of the tank cover, which further aggravates exhaust gas leakage. Moreover, the workpieces are statically pickled in the tank, which cannot achieve dynamic stirring, resulting in low pickling efficiency and difficulty in meeting the needs of mass production. Therefore, a pickling tank with a zoned exhaust gas collection structure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an acid washing tank with a partitioned waste gas collection structure, which aims to improve the problems mentioned above.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an acid pickling tank with a partitioned waste gas collection structure, including an acid pickling chamber, an exhaust pipe fixedly connected to the top of the acid pickling chamber, and a rotating mechanism provided on the top of the acid pickling chamber;

[0006] The rotating mechanism includes a rotating ring, which is rotatably connected to the top of the pickling tank and is inclined. The rotating ring has several placement slots, and a sealing gasket is provided at the position where the top of the pickling tank contacts the rotating ring.

[0007] As a further description of the above technical solution: a support frame is fixedly connected to the top of the pickling tank, a motor is fixedly connected to the support frame, and the rotating shaft at the output end of the motor is fixedly connected to the rotating ring.

[0008] As a further description of the above technical solution: the inner wall of the placement tank is rotatably connected to an immersion chamber, and the immersion chamber has several water inlet holes at one end near the inner ring of the rotating ring.

[0009] As a further description of the above technical solution: the immersion chamber is provided with a cover at one end near the outer ring of the rotating ring, and the outer wall of the immersion chamber is provided with an elastic buckle at the position of the outer wall of the cover to lock the slot opened on the cover.

[0010] As a further description of the above technical solution: the inner wall of the immersion chamber is provided with a placement cylinder, and the placement cylinder has several water inlet holes at one end near the inner ring of the rotating ring.

[0011] As a further description of the above technical solution: a handle is fixedly connected to one end of the placement cylinder near the outer ring of the rotating ring.

[0012] As a further description of the above technical solution: the top of the rotating ring is rotatably connected to a toothed ring, the toothed ring is fixedly connected to the pickling chamber, and a gear is fixedly sleeved on the outer wall of the immersion chamber at the position corresponding to the toothed ring, and the gear meshes with the toothed ring.

[0013] As a further description of the above technical solution: the rotating ring is tilted at 30 degrees, the exhaust pipe is located above the pickling chamber and above the downward tilting end of the rotating ring, and the rotating ring is at any angle so that the placement tank is not simultaneously located inside and outside the pickling chamber.

[0014] This utility model has the following beneficial effects:

[0015] I. In this utility model, the partitioned design enhances safety and environmental protection: By opening several placement slots on the rotating ring, the workpieces can be placed in partitions, avoiding collisions and damage between the workpieces. Furthermore, the placement slots will not be inside or outside the pickling chamber at any angle of the rotating ring, preventing solution leakage and waste gas overflow. At the same time, a sealing gasket is set at the contact position between the top of the pickling chamber and the rotating ring to ensure that the placement slots inside the pickling chamber are completely sealed, effectively preventing pickling waste gas leakage.

[0016] II. In this utility model, dynamic pickling improves processing quality and efficiency: the rotating ring is set at an angle, and when the rotating ring rotates, it drives the immersion chamber to move synchronously, so that the immersion chamber is alternately inside the pickling chamber (pickling) and outside (removing and placing workpieces). Workpiece replacement can be completed without opening the pickling chamber cover, improving operational convenience; at the same time, the toothed ring connected to the top of the rotating ring meshes with the gear on the outer wall of the immersion chamber. When the rotating ring rotates, it drives the immersion chamber to rotate, causing the workpieces in the placement cylinder to tumble, ensuring that the workpieces are in full contact with the pickling solution, avoiding uneven pickling, and significantly improving pickling quality and efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 5This utility model provides an embodiment of an acid pickling tank with a partitioned waste gas collection structure, including an acid pickling chamber 1. An exhaust pipe 5 is fixedly connected to the top of the acid pickling chamber 1 for collecting waste gas generated during acid pickling. A rotating mechanism is provided on the top of the acid pickling chamber 1, including a rotating ring 2 rotatably connected to the top of the acid pickling chamber 1 and inclined. The rotating ring 2 has several placement slots 21. A sealing gasket is provided at the contact point between the top of the acid pickling chamber 1 and the rotating ring 2. By providing several placement slots 21 on the rotating ring 2, the workpieces can be distinguished when placed for acid pickling, avoiding damage from collisions or insufficient contact with the solution due to accumulation, thus affecting the acid pickling process. The rotating ring 2 is tilted and positioned at the top of the pickling chamber 1, so that the lower part of the placement tank 21 of the rotating ring 2 is immersed in the solution in the pickling chamber 1, while the upper part is outside the pickling chamber 1. The sealing gasket set at the top of the pickling chamber 1 can ensure that the placement tank 21 inside the pickling chamber 1 is not connected to the outside, which can effectively prevent the leakage of harmful gases during pickling. The placement tank 21 outside the pickling chamber 1 is used to place other workpieces to be pickled, or to remove workpieces that have been pickled. A support frame 3 is fixedly connected to the top of the pickling chamber 1, and a motor 4 is fixedly connected to the support frame 3. The rotating shaft at the output end of the motor 4 is fixedly connected to the rotating ring 2, and the motor 4 is used to drive the rotating ring 2 to rotate.

[0026] Reference Figure 1 - Figure 5 An immersion chamber 22 is rotatably connected to the inner wall of the placement tank 21. Several water inlets are provided at the end of the immersion chamber 22 near the inner ring of the rotating ring 2. A cover 222 is provided at the end of the immersion chamber 22 near the outer ring of the rotating ring 2. An elastic buckle 223 is provided on the outer wall of the immersion chamber 22 at the position of the outer wall of the cover 222 to lock the slot opened on the cover 222. A placement cylinder 24 is placed on the inner wall of the immersion chamber 22. Several water inlets are provided at the end of the placement cylinder 24 near the inner ring of the rotating ring 2 to facilitate the flow of solution. A handle 241 is fixedly connected to the end of the placement cylinder 24 near the outer ring of the rotating ring 2 for placing the workpiece in the placement cylinder 24 so as to facilitate the extraction by pulling the handle 241.

[0027] Reference Figure 1 - Figure 5 A toothed ring 23 is rotatably connected to the top of the rotating ring 2. The toothed ring 23 is fixedly connected to the pickling tank 1. A gear 221 is fixedly sleeved on the outer wall of the immersion tank 22 at the position corresponding to the toothed ring 23, and the gear 221 meshes with the toothed ring 23. By setting the toothed ring 23, when the rotating ring 2 drives the immersion tank 22 in the placement tank 21 to rotate together, the immersion tank 22 rotates due to the meshing transmission of the gear 221 and the toothed ring 23. The workpiece in the placement cylinder 24 in the immersion tank 22 tumbles, further improving the cleaning effect.

[0028] Reference Figure 1 - Figure 5 The rotating ring 2 is tilted at 30 degrees, and the exhaust pipe 5 is located above the pickling chamber 1, above the downward tilting end of the rotating ring 2. The rotating ring 2 is at any angle so that the placement tank 21 is partially inside and outside the pickling chamber 1 at the same time.

[0029] Working principle: Workpiece placement stage: The operator first opens the hatch cover 222 on the immersion chamber 22 and releases it from the slot of the hatch cover 222 by bending the elastic buckle 223. The metal workpiece to be pickled is placed into the placement cylinder 24. Then the hatch cover 222 is closed and fixed by the elastic buckle 223. At this time, the rotating ring 2 is in the initial position and above the rotating ring 2. The operator can place multiple workpieces in sequence.

[0030] Pickling start-up stage: Start the motor 4 on the support frame 3. The output shaft of the motor 4 drives the rotating ring 2 to rotate along the top of the pickling chamber 1. Since the rotating ring 2 is set at a 30-degree angle, as the rotating ring 2 rotates, the placement tank 21, which was originally above the rotating ring 2, gradually moves into the interior of the pickling chamber 1 and eventually enters the pickling solution of the pickling chamber 1 completely. At this time, the water inlet holes of the immersion chamber 22 and the placement cylinder 24 are both immersed in the solution. The solution enters the placement cylinder 24 through the water inlet holes, contacts the workpiece, and begins the pickling reaction.

[0031] Dynamic pickling stage: During the continuous rotation of the rotating ring 2, the gear 221 on the outer wall of the immersion chamber 22 meshes with the gear ring 23. Since the gear ring 23 is fixed, the gear 221 rotates on its own axis while revolving with the rotating ring 2, thereby driving the immersion chamber 22 and the internal placement cylinder 24 to rotate together. The workpiece in the placement cylinder 24 tumbles continuously under the action of rotation, ensuring that all surfaces of the workpiece can fully contact the pickling solution and avoid incomplete pickling in some areas. At the same time, the harmful waste gas generated during the pickling process is confined in the sealed pickling chamber 1 and is finally discharged through the exhaust pipe 5 at the top of the pickling chamber 1 for subsequent treatment to prevent waste gas leakage.

[0032] Workpiece Removal Stage: After the workpiece has completed the preset pickling time, the motor 4 continues to drive the rotating ring 2 to rotate. The placement tank 21, which was originally inside the pickling chamber 1, gradually moves upward to the top of the rotating ring 2 and is removed from the pickling solution. After the placement tank 21 has completely moved outside the pickling chamber 1, the motor 4 is turned off, and the operator opens the corresponding cover 222 and removes the placement cylinder 24 from the immersion chamber 22 by pulling the handle 241, thus completing the pickling and recovery of the workpiece. The above steps can then be repeated to process new workpieces to be pickled, thereby achieving continuous pickling operations.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
