Detailed Implementation

[0026] 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.

[0027] Example 1: A drying device for hot-dip galvanizing of steel components, such as... Figures 1 to 3 As shown, the device includes a waste liquid collection box 1 and an outward-folding guide cover 2 that is threaded onto the upper surface of the waste liquid collection box 1. A circular placement groove 13 is provided on the upper wall of the inner cavity of the waste liquid collection box 1. A rotating assembly is installed inside the placement groove 13. The rotating assembly includes a rotating base 11 installed at the center of the placement groove 13, a rotating column 12 rotatably connected to the top of the rotating base 11, and four circumferentially distributed mounting bases 3 on the outer wall of the rotating column 12. A first scraper 4 is connected to the bottom of each mounting base 3. A detachable connecting rod 6 is inclinedly provided on the top of the mounting base 3. The movable end of the connecting rod 6 is slidably connected to the upper surface of the outward-folding guide cover 2 through a rolling mechanism. A second scraper 8 with an arc-shaped structure is connected to the side wall of each connecting rod 6 near the inner wall of the outward-folding guide cover 2.

[0028] In order to ensure that the waste liquid inside the placement tank 13 can be effectively discharged, a discharge tank 9 that connects to the outside is provided at the edge of the inner cavity of the placement tank 13.

[0029] To avoid wear on the inner walls of the waste liquid collection box 1 and the outward-folding guide cover 2, both the first scraper 4 and the second scraper 8 are made of rubber.

[0030] like Figure 2 As shown, in order to ensure that the second scraper 8 can rotate under the rotation of the mounting base 3 and will not cause wear on the upper surface of the outward-turning guide cover 2, the rolling mechanism includes a connecting block 5 connected by welding process on the movable end of each connecting support rod 6, a ball bearing 7 rolledly connected to the lower end of the connecting block 5, and a U-shaped sliding track 16 fixedly installed on the top upper surface of the outward-turning guide cover 2 to accommodate the sliding of the ball bearing 7.

[0031] The working principle of this utility model is as follows: the first scraper 4 and the second scraper 8 are driven by the rotating component to rotate the four mounting bases 3 360 degrees. During the rotation, the first scraper 4 connected to the bottom of the mounting base 3 can perform a circumferential scraping operation on the upper surface of the inner cavity of the waste liquid collection box 1, so as to avoid the residue in the waste liquid hanging on the inner wall of the waste liquid collection box 1 and forming a scale layer over time, which would affect the service life of the waste liquid collection box 1 and the cleanliness during use.

[0032] Simultaneously, with the cooperation of the rolling mechanism, the connecting rod 6 can rotate synchronously when the mounting base 3 rotates, so that the arc-shaped second scraper 8 can contact the arc-shaped inner wall surface of the outward-folding guide cover 2, thereby achieving the purpose of cleaning the dirt on the inner wall surface of the outward-folding guide cover 2.

[0033] The first scraper 4 and the second scraper 8, made of rubber, can protect the inner walls of the waste liquid receiving box 1 and the outward-turning guide cover 2 while scraping away dirt, thus preventing scratches on the inner walls and affecting their service life.

[0034] Example 2: Based on Example 1, as follows Figure 4 As shown, four circumferentially distributed "T"-shaped mounting grooves 14 are provided on the outer wall of the rotating column 12. Each of the four mounting bases 3 has a slider that can be engaged inside the mounting groove 14 welded to one end near the rotating column 12. The bottom of the limiting top cover 10 has a limiting engagement groove 15 with the same shape as the upper surface of the rotating column 12.

[0035] The working principle of this utility model is as follows: Through the "T"-shaped mounting groove 14 and the slider, the four mounting bases 3 can be easily snapped onto the outer wall of the rotating column 12, which facilitates the assembly, disassembly and replacement of the bases. The structure is simple and can be operated without the need for professional personnel.

[0036] When in use, the user can pull the limiting top cover 10 out from the top of the rotating column 12, and then the mounting base 3 is vertically downward along the axis of the mounting slide 14, so that the slider is fully engaged and fixed inside the mounting slide 14. After the mounting base 3 is installed, the user can use the limiting engagement groove 15 to make the limiting top cover 10 firmly engaged with the top of the rotating column 12. When one of the mounting bases 3 malfunctions and needs to be replaced, the user only needs to remove the limiting top cover 10 from the top of the rotating column 12 to remove and replace the mounting base 3, which effectively reduces economic losses compared to disassembling and replacing the entire component.

[0037] Example 3: Based on Example 1, as follows Figure 4 As shown, a negative magnetic absorbing sheet is fixedly connected to the upper outer wall of the rotating column 12, and a positive magnetic absorbing sheet is provided inside the limiting top cover 10.

[0038] The working principle of this utility model is as follows: Under the action of the mutually attracting magnetic plates, the firmness of the limiting top cover 10 engaging with the upper end of the rotating column 12 can be strengthened, preventing the limiting top cover 10 from falling off the upper end of the rotating column 12 due to weak firmness, and preventing the mounting base 3 from sliding out of the mounting groove 14 in the event of excessive waste liquid, thus effectively ensuring the orderly progress of dirt cleaning operations.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
