Description

Technical Field

[0001] The utility model relates to the technical field of pickling equipment, in particular to a pickling equipment for the production of stainless steel water pipes. Background Technique

[0002] In the production of stainless steel water pipes, it is necessary to passivate the preliminarily formed water pipes. The previous step of passivation is pickling. One of the purposes of pickling is to create conditions for passivation treatment and ensure the formation of a good passivation film. Because through pickling, an average of 10um thick layer on the surface of the stainless steel is corroded. The chemical activity of the acid solution makes the dissolution rate of the defect part higher than that of other parts on the surface. Therefore, pickling can make the whole surface tend to be evenly balanced and eliminate some potential hazards that are prone to cause corrosion. When the existing pickling equipment for the production of stainless steel water pipes is in use, it cannot achieve uniform pickling operation on the whole body of the stainless steel water pipe, and will be affected by the bubbles generated on the whole body of the stainless steel water pipe, thus affecting the pickling effect. Moreover, when removing the stainless steel water pipe after pickling, there will be more acid pickling solution remaining on the inner wall of the stainless steel water pipe, resulting in a relatively fast consumption of the acid pickling solution.

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment

[0023] As Figures 1-4As shown in the figure, a pickling device for the production of stainless steel water pipes proposed in an embodiment of the present utility model includes a pickling tank 1, a placing cylinder 2, a fixed cover 3, a driving component 4, and a lifting component 5. The pickling device designed in this solution can achieve uniform pickling operation of stainless steel water pipes, and can conveniently drain the residual pickling solution inside the stainless steel water pipes after pickling, avoiding waste of pickling solution. A placing cylinder 2 is arranged in the cavity of the pickling tank 1 in a matching manner. The placing cylinder 2 is rotatably connected to the fixed cover 3. A driving component 4 is fixedly connected to the fixed cover 3, and the driving component 4 is connected to the placing cylinder 2 in a matching manner. The fixed cover 3 is rotatably connected to the lifting component 5, and the lifting component 5 is fixedly connected to the pickling tank 1. This device is electrically connected to an external control device through a transmission wire, and the operation state of this device is controlled by the external control device. Place several stainless steel water pipes inside the placing cylinder 2, and then control the operation of the lifting component 5 to lower the air cylinder 501. At this time, the placing cylinder 2 will be immersed in the pickling tank 1. The pickling tank 1 is filled with pickling solution, so the stainless steel water pipes will be immersed below the liquid level of the pickling solution. At this time, rotate the motor 401, and the transmission belt 403 drives the transmission ring 202 to rotate through the rotating wheel 402. Since the placing cylinder 2 is rotatably connected inside the fixed cover 3 through the connection between the convex ring 201 and the rotating groove 302, the driving component 4 can drive the placing cylinder 2 to rotate. Due to the rotation of the placing cylinder 2, the stainless steel water pipes inside the placing cylinder 2 will roll, so that the stainless steel water pipes will not remain stationary below the liquid level of the pickling solution, improving the pickling effect of the stainless steel water pipes. After the pickling of the stainless steel water pipes is completed, by raising the air cylinder 501, the placing cylinder 2 can be lifted, making the stainless steel water pipes higher than the liquid level of the pickling solution. At this time, the residual pickling solution on the outer wall of the stainless steel water pipes will flow out from the drain hole 301, while there will still be a lot of pickling solution remaining on the inner wall of the stainless steel water pipes. At this time, through the coordinated adjustment of the two symmetrically arranged air cylinders 501, the two connecting shafts 502 are in a state of one high and one low. Since the connecting shafts 502 are rotatably connected in the rotating seats 304, when the two connecting shafts 502 are at different heights, the two ends of the fixed cover 3 will be at different heights, and the two ends of the placing cylinder 2 will also be at different heights. The height difference between the two ends is not more than thirty degrees, ensuring that the stainless steel water pipes can slide inside the placing cylinder 2 to meet the use requirements. By having different heights at both ends, the residual pickling solution on the inner wall of the stainless steel water pipes can be drained, avoiding waste of residual pickling solution. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] As Figure 4 shown, in some embodiments, the drive assembly 4 is composed of a motor 401, a rotating wheel 402, and a transmission belt 403. The motors 401 are symmetrically and fixedly connected to the fixing plate 303, a rotating wheel 402 is fixedly connected to the output shaft of the motor 401, the rotating wheel 402 is cooperatively connected with the transmission belt 403, and the transmission belt 403 is cooperatively connected with the drive ring 202. The drive assembly 4 can make the placement cylinder 2 rotate inside the fixed cover 3, and through rotation, uniform pickling operations can be performed on the whole body of the stainless steel water pipe.

[0028] As Figure 4 shown, in some embodiments, the lifting assembly 5 is composed of a cylinder 501 and a connecting shaft 502. The cylinders 501 are symmetrically arranged in pairs, the cylinders 501 are fixedly connected to the fixed seat 101, a connecting shaft 502 is fixedly connected to the output shaft of the cylinder 501, and the connecting shaft 502 is rotatably connected to the rotating seat 304. The design of the lifting assembly 5 meets the usage requirements, ensures that pickling operations can be controlled on the stainless steel water pipe, and enables the acid pickling solution on the stainless steel water pipe to be drained for use.
