[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-5As shown, the drying device for pickling and passivating stainless steel water pipes includes an outer frame 1 and an adsorption ring 9 inside the outer frame 1. Circular rings 7 are arranged on both sides of the adsorption ring 9 inside the outer frame 1. Several rotating plates 6 arranged in a ring array are hinged to the inner side of each circular ring 7. An electric telescopic rod 8 is hinged between the inner wall of each circular ring 7 and any of the rotating plates 6. The difference is that one of the two circular rings 7 has a hollowed-out surface and is fixedly installed inside the outer frame 1, while the other circular ring 7 is slidably connected to the inner wall of the outer frame 1 and fixedly connected to the inner wall of the end face of the outer frame 1 with several electric push rods 13. A water collecting ring 12 is installed on the outer wall of the outer frame 1 at the hollowed-out circular ring 7. The water collecting ring 12 is spatially connected to one side of the hollowed-out circular ring 7 inside the outer frame 1. In practical use, the outer frame 1 is fitted onto the stainless steel water pipe. As the outer frame 1 moves along the surface of the stainless steel water pipe, the internal adsorption ring 9 absorbs residual water stains on the surface of the water pipe. During the movement of the outer frame 1, it can be operated periodically. During operation, the outer frame 1 stops moving, and the electric telescopic rod 8 extends to rotate the corresponding rotating plate 6 to be horizontal with the ring 7. This uses several rotating plates 6 to block the space between the inner side of the ring 7 and the outer wall of the water pipe. Then, the electric push rod 13 extends, causing another slidingly installed ring 7 to move and squeeze the adsorption ring 9. Through this squeezing, the water stains adsorbed in the adsorption ring 9 are discharged along the perforated surface of the ring 7. Additionally, as... Figure 3 As shown, it can also be seen that the inner side of the hollowed-out ring 7 protrudes upward in a ring shape. Therefore, the water that accumulates through the hollowed-out area will not enter the area of ​​the rotating plate 6, but will enter the water collection ring 12. Therefore, in actual operation, a hose can be connected to the drain of the water collection ring 12 to guide the water to the corresponding container. After the water is squeezed and dehydrated, the slid-mounted ring 7 is reset, and at the same time, the electric telescopic rod 8 retracts to reopen the rotating plate 6. The outer frame 1 can then continue to move along the outer wall of the water pipe to continue absorbing water stains.

[0025] Furthermore: A plurality of clamping arms 3 arranged in a circular array are rotatably connected to one end edge of the outer frame 1. The clamping arms 3 are V-shaped, and one swinging edge of the clamping arm 3 extends to the side of the outer frame 1. A threaded ring 5 for pushing one swinging edge of the clamping arm 3 is threadedly connected to the outer side of the outer frame 1. The clamping arm 3 is rotatably mounted on the outer frame 1 via a torsion spring, and an electric roller 4 for abutting against the outer wall of the stainless steel water pipe is installed on the other swinging edge of the clamping arm 3. Figure 3 As shown, by rotating the threaded ring 5, the threaded ring 5 moves upward. The contact between the threaded ring 5 and the swinging edge below the clamping arm 3 can push the clamping arm 3 to swing against the torsion of the torsion spring. This allows the electric roller 4 on the swinging edge above the clamping arm 3 to press against the outer wall of the water pipe. The electric roller 4 can then roll on the surface of the water pipe, allowing the outer frame 1 to move on the outer wall of the water pipe.

[0026] Furthermore, it also includes an inner frame 2, which moves inside the water pipe. At least two inner frames 2 are provided, aligned along the same center line. Several telescopic columns 10 arranged in a circular array are provided through the inner wall of the inner frame 2. Electric rollers 4 are also installed at the ends of the telescopic columns 10, and these electric rollers 4 are used to contact the inner wall of the stainless steel water pipe. Nuts 11 are threaded onto the inner wall of the inner frame 2. The outer side of the nut 11 is tapered, and the outer side of the nut 11 slides against the end of the telescopic column 10 away from the electric rollers 4. Figure 5 As shown, by rotating the mounting nut 11, the inclined edge of the outer side of the nut 11 can push the telescopic column 10 away from the center line of the inner frame 2, thereby making the electric roller 4 at the end of the telescopic column 10 contact the inner wall of the water pipe. Therefore, the inner frame 2 can be moved inside the water pipe by rotating the electric roller 4 on the telescopic column 10. Several inner frames 2 are fixedly connected to the center line through the air inlet pipe 14. One end of the air inlet pipe 14 extends to the inner frame 2 located on one of the outer sides and is connected to the air outlet 15. The outer side of the air outlet 15 is hollow and is installed on the end face of the inner frame 2. The air inlet pipe 14 and the air outlet 15 are used to dry the inner wall of the stainless steel water pipe. During the movement of the inner frame 2, the air inlet pipe 14 is connected through a hose, and hot air is introduced into the air inlet pipe 14 through the hose. The hot air can be blown out from the hole on the side of the air outlet 15 and act on the inner wall of the water pipe to dry the inner wall of the water pipe. When the water pipe is heated, the outer wall of the water pipe can also be dried.

[0027] The working principle is as follows: the outer frame 1 is fitted onto the outer wall of the water pipe, and the inner frame 2 is installed inside the water pipe. The electric rollers 4 on the outer frame 1 and the inner frame 2 are respectively fitted against the outer and inner walls of the water pipe by rotating the threaded ring 5 and the nut 11. The operation of the electric rollers 4 enables the outer frame 1 and the inner frame 2 to move outside and inside the water pipe. When the outer frame 1 moves, the internal adsorption ring 9 absorbs water stains on the outer wall. When the inner frame 2 moves, the hot air blown by the air outlet 15 dries the inner wall of the water pipe. When the adsorption ring 9 is saturated or about to be saturated, the electric push rod 13 extends to move another sliding ring 7, which drives several rotating plates 6 on its inner side to move and squeeze the adsorption ring 9. After squeezing, the water stains adsorbed in the adsorption ring 9 are discharged along the hollowed-out holes on the surface of the hollowed-out ring 7. The water accumulated through the hollowed-out holes enters the water collection ring 12 for discharge.

[0028] The wiring diagrams for the electric roller 4, electric telescopic rod 8, and electric push rod 13 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts for the electric roller 4, electric telescopic rod 8, and electric push rod 13 will not be explained in detail.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
