Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a surface treatment pickling tank. Background Art

[0002] The method of using acid solution to remove scale and rust on the surface of steel is called pickling. It is a method of cleaning the metal surface. It is usually carried out together with pre-filming. Generally, the workpiece is immersed in an aqueous solution of sulfuric acid to remove oxides and other films on the metal surface. It is a pre-treatment or intermediate treatment for processes such as electroplating, enameling, and rolling.

[0003] However, in the prior art, after the pipe fittings are rolled, their surfaces generally need to be cleaned to facilitate subsequent surface processing. However, in the current pickling process, manual hand-held pickling is required to discharge and take out materials, which is time-consuming and labor-intensive. In addition, a large amount of acidic waste gas will be generated during the pickling process. The direct discharge and diffusion of the waste gas not only pollutes the environment, but also endangers the health of the workers. Utility Model Content

The pipe material slides into the upper end of the displacement block along the slope of the top of the fixed block. At this time, the telescopic cylinder is started to drive the connecting rod to move upward, so that the displacement block pushes the pipe material to move to the fixed block of the previous step. At this time, the telescopic cylinder moves downward again, so that the displacement block descends, and the pipe material slides into the displacement block of the previous step again. With the continuous rise and fall of the displacement block, a stepping effect is achieved, thereby conveying the pipe material.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The utility model arranges a feeding device, and when the pipe material is pickled, a guide plate guides the moving direction, and as the displacement block continues to rise and fall, a stepping effect is achieved, so that the pipe material is transported out of the tank body and slides into the placement rack outside the tank body for storage, which solves the problem of manual material discharge and material collection during pickling of the pipe material, saves time, and multiple pipe materials can be pickled at the same time, thereby saving human resources.

[0020] The outer wall of the displacement block 405 is slidably connected to the outer wall of the fixed block 402, and the outer wall of the displacement block 405 is slidably connected to the inner wall of the limit shell 401. The telescopic cylinder 403 is started to drive the fixedly connected connecting rod 404 to move upward, so that the displacement block 405 slides on the inner wall of the limit shell 401, so that the displacement block 405 pushes the pipe material to move to the fixed block 402 of the previous step. At this time, the telescopic cylinder 403 moves downward again, so that the displacement block 405 descends, and the pipe material slides onto the displacement block 405 of the previous step again. As the displacement block 405 continues to rise and fall, a stepping effect is achieved, thereby transporting the pipe material up.

[0021] The outer wall of the limiting shell 401 is fixedly connected to the inner wall of the tank body 1, and the outer wall of the limiting shell 401 is fixedly connected to the outer wall of the guide plate 5. The pipe material moves downward on the guide plate 5 and is pickled by the solution in the tank body 1 until the pipe material moves to the feeding device 4 fixedly connected thereto.

[0022] The exhaust device 3 includes an exhaust pipe 301, the middle end of the inner wall of the exhaust pipe 301 is fixedly connected to a motor 304 through a frame, the top of the inner wall of the exhaust pipe 301 is movably connected to a filter block 302, the top of the exhaust pipe 301 is threadedly connected to a locking ring 303, and the output end of the motor 304 is fixedly connected to a fan blade 305. The bottom end of the inner wall of the exhaust pipe 301 is fixedly connected to a guide plate 306, the inner wall of the guide plate 306 is fixedly connected to a fixed rod 308, and the end of the fixed rod 308 away from the guide plate 306 is fixedly connected to a protective plate 307. The motor 304 drives the fixedly connected fan blade 305 to rotate, sucks the gas generated during the pickling process, enters the exhaust pipe 301 through the gap between the guide plate 306 and the protective plate 307 connected to the fixed rod 308, and is purified by the filter block 302 in the exhaust pipe 301.

[0023] The outer wall of the exhaust pipe 301 is fixedly connected to the inner wall of the tank body 1, and the outer wall of the filter block 302 is slidably connected to the outer wall of the locking ring 303. After rotating the locking ring 303 threadedly connected to the exhaust pipe 301 and removing the locking ring 303, the filter block 302 can be taken out of the exhaust pipe 301 for cleaning and replacement.

[0024] Working principle:

[0025] When in use, the pipe material is put into the opening on the tank body 1 and placed on the guide plate 5. Guided by the guide plate 5, the pipe material moves downward on the guide plate 5 and is pickled by the solution in the tank body 1 until the pipe material moves to the feeding device 4. At this time, the displacement block 405 is at the bottom of the fixed block 402, and the pipe material slides into the upper end of the displacement block 405 along the slope of the top of the fixed block 402. At this time, the telescopic cylinder 403 is started to drive the connecting rod 404 to move upward, so that the displacement block 405 slides in the limiting shell 401, so that the displacement block 405 pushes the pipe material to move to the fixed block 402 of the upper stage. At this time, the telescopic cylinder 403 moves downward again, causing the displacement block 405 to descend, and the pipe material slides into the displacement block 405 of the upper stage again. As the displacement block 405 continues to rise and fall, a stepping effect is achieved, thereby transporting the pipe material up. When it reaches the top, the pipe material leaves the feeding device 4 and slides into the placement rack 2 outside the tank body 1 for storage;

[0026] During the pickling process, the motor 304 drives the fan blade 305 to rotate through the exhaust device 3, and the gas generated during the pickling process is sucked. The gas enters the exhaust pipe 301 through the gap between the guide plate 306 and the protective plate 307 connected to the fixed rod 308, and is purified by the filter block 302 in the exhaust pipe 301, and then discharged from the top of the exhaust pipe 301. The guide plate 306 and the protective plate 307 connected to the fixed rod 308 prevent the acidic solution from splashing when the pipe material enters the tank body 1, and enters the exhaust device 3 to cause corrosion damage. After long-term use, the threaded locking ring 303 is rotated, and after removing the locking ring 303, the filter block 302 can be taken out from the exhaust pipe 301 for cleaning and replacement.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
