DETAILED DESCRIPTION

[0021] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, the utility model discloses an impurity removal device that can be used for the surface of a stainless steel welded pipe, comprising a mounting frame 1, the middle part of the mounting frame 1 is through-through and a mounting hole 14 for mounting on a conveying platform is provided on the mounting frame 1, a flexible scraper 2 is provided in the middle part of the mounting frame 1, a retaining frame 3 for maintaining the shape of the flexible scraper 2 is fixedly provided on the outer side of the flexible scraper 2, and the retaining frame 3 is installed on the mounting frame 1, and at the same time, the flexible scraper 2 is an annular structure and a ring-shaped lip 21 is integrally formed in the middle part thereof, as shown in FIG. Figure 2 As shown, the front and rear end surfaces of the lip 21 are both arc surfaces. When the stainless steel welded pipe passes through the middle of the flexible scraper 2, the lip 21 can be used to scrape off impurities on the surface of the stainless steel welded pipe.

[0024] The flexible scraper 2 can be flipped forward and backward on the mounting frame 1 to change the direction of the lip 21. The specific solution is as follows:

[0025] The mounting frame 1 is provided with a rotating mechanism for rotating the retaining frame 3, and the rotating mechanism includes an annular ring 11 and an annular slide groove 12 opened at the upper end of the annular ring 11. In this structure, the annular ring 11 is fixedly provided on the mounting frame 1, and a sliding column 31 for sliding in the annular slide groove 12 is fixedly provided on the retaining frame 3. A connecting arm 32 is provided between the sliding column 31 and the retaining frame 3. Through the connecting arm 32 and the connection relationship between the sliding column 31 and the annular ring 11, the retaining frame 3 can not only rotate the front and rear end surfaces of the flexible scraper 2 with the help of the sliding column 31, but also be suspended on the annular ring 11 with the help of the connecting arm 32.

[0026] A connecting plate 33 is provided on the retaining frame 3, and a first threaded hole 34 is opened on the connecting plate 33. At the same time, a plurality of second threaded holes 13 are opened on the annular ring 11. When the retaining frame 3 rotates, the first threaded hole 34 can overlap with the second threaded hole 13 on the path. In addition, a fixing mechanism for fixing the position of the sliding column 31 is provided on the mounting frame 1. The fixing mechanism specifically includes a screw 4 for threadedly matching with the first threaded hole 34 and the second threaded hole 13.

[0027] The working principle of the above structure is as follows: the mounting frame 1 can be installed on the conveying frame of the stainless steel welded pipe. When the stainless steel welded pipe is transferred on the conveying frame, it can pass through the middle part of the flexible scraper 2. At this time, the lip 21 on the flexible scraper 2 can be used to scrape off impurities on the surface of the stainless steel welded pipe, so that the stainless steel welded pipe can directly complete the surface cleaning work during the conveying and transfer process. At the same time, in order to further facilitate the surface cleaning work of the stainless steel welded pipe, the rotation of the front and rear end faces of the flexible scraper 2 can be completed by the sliding of the sliding column 31 on the annular slide groove 12. When the flexible scraper 2 is adjusted to the appropriate position, it can be fixed with the screw 4. The advantage is that when the conveying direction of the stainless steel welded pipe changes, the flexible scraper 2 can be directly flipped in accordance with the new conveying direction instead of reinstalling the mounting frame 1.

[0028] Furthermore, the flexible scraper 2 and the retaining frame 3 are grouped in pairs, and each flexible scraper 2 is equipped with a retaining frame 3, and the retaining frames 3 in the same group are fixedly connected to each other. At the same time, arc-shaped guide arc surfaces 22 and guide slopes 23 are formed on the front and rear end surfaces of the flexible scraper 2. The guide arc surface 22 is arranged around the outer edge of the flexible scraper 2 and its surrounding angle is less than 360°. At the same time, each guide arc surface 22 is equipped with two guide slopes 23, and the guide slopes 23 are arranged at the lower end of the flexible scraper 2 and are used to connect with the end of the guide arc surface 22.

[0029] The working principle of this structure is as follows: this structure can be used in conjunction with other impurity removal mechanisms. For example, during the transmission of stainless steel welded pipes, a water injection mechanism can be installed between the two flexible scrapers 2 to spray water on the surface of the stainless steel welded pipe. At this time, the water flow can wash away some impurities on the surface of the stainless steel welded pipe, which is beneficial to reducing the working pressure of the flexible scraper 2. The combination of the guide arc surface 22 and the guide slope 23 can make the water on the surface of the stainless steel welded pipe flow downward along the side wall of the flexible scraper 2 when it contacts the flexible scraper 2, thereby collecting the water flow. The setting of the two flexible scrapers 2 is beneficial to limiting the flow range of the water flow, and the retaining frames 3 on the two flexible scrapers 2 are fixedly connected to each other, which can further enable the flexible scraper 2 to be vertically suspended on the annular ring 11 to prevent its angle from deviating.

[0030] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
