[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-4 The utility model provides a technical solution: a boiler seal that is easy to replace Figure 1 、 Figure 2 and Figure 3 As shown, the rotary sealing assembly 1 includes a boiler body 11, a fixed block 12 is fixed on the right side of the boiler body 11, and the fixed block 12 is rotatably connected to a fixed plate 14 via a rotating rod 13. A top cover 15 is fixed to the fixed plate 14, and a first sealing member 16 is fixed to the top cover 15. A sealing ring 17 is embedded in the upper side of the interior of the boiler body 11. A handle 18 is rotatably connected to the top cover 15. The first sealing member 16 includes a sealing plate, and the sealing ring 17 passes through the sealing plate.
[0022] The boiler body 11 is provided with a control device for controlling the entire device. Two groups of fixed blocks 12 are provided. The two groups of fixed blocks 12 are symmetrically arranged. The two groups of fixed blocks 12 are rotatably connected to the fixed plate 14 through the rotating rod 13. The first sealing member 16 is hollow.
[0023] In the above solution, the staff pulls the handle 18, and the top cover 15 rotates with the assistance of the rotating rod 13 between the fixed block 12 and the fixed plate 14. The top cover 15 is separated from the boiler body 11, and the sealing ring 17 on the first sealing member 16 and the sealing ring 17 embedded in the boiler body 11 are removed, thereby facilitating the replacement of the sealing ring 17 and also facilitating the staff to clean and maintain the interior of the boiler body 11.
[0024] like Figure 1 and Figure 3 As shown, a limit adjustment structure 2 is fixed on the rotary sealing assembly 1 and is used for boiler sealing. The limit adjustment structure 2 includes a height adjustment assembly 21, a limit assembly 22 is fixed on the height adjustment assembly 21, and the height adjustment assembly 21 includes an annular plate 211. The annular plate 211 adjusts the position of the motor box 212 through a telescopic structure. A first support plate 213 is fixed on the upper side of the motor box 212. The motor in the motor box 212 drives the fixed rod 216 to rotate. A slider 214 is fixed on the first support plate 213. The slider 214 is slidably connected to a slide groove 215. The slide groove 215 is provided on the boiler body 11;
[0025] There are five sets of height adjustment components 21, and the five sets of height adjustment components 21 are symmetrically arranged about the central axis of the boiler body 11, and the boiler body 11 is arranged in a ring shape;
[0026] Specifically, the telescopic structure in the present application is a hydraulic cylinder, and the motor is a stepping motor. Both the stepping motor and the hydraulic cylinder are prior art. The inner diameter of the annular plate 211 is the same as the diameter of the boiler body 11.
[0027] In the above scheme, with the assistance of the hydraulic cylinder on the annular plate 211, the first support plate 213 on the upper side of the motor box 212 is driven upward by the hydraulic rod. The first support plate 213 moves upward, and the slider 214 on the first support plate 213 slides in the slide groove 215. With the assistance of the stepping motor in the motor box 212, the fixing rod 216 is driven to rotate to 180°, thereby driving the limit assembly 22 to separate from the top cover 15, making it easier to open the top cover 15 later.
[0028] like Figure 1 、 Figure 3 and Figure 4 As shown, the limiting assembly 22 includes a connecting plate 221, a second support plate 222 is fixed on the connecting plate 221, and the second support plate 222 is telescopically adjusted to adjust the position of the limiting compacting plate 223 through a telescopic structure;
[0029] Among them, there are five groups of limit assemblies 22, which are symmetrically arranged about the central axis of the top cover 15. The connecting plate 221 is perpendicular to the second support plate 222, and a connecting rod is fixed between the connecting plate 221 and the second support plate 222. The setting of the connecting rod ensures the stability between the second support plate 222 and the connecting plate 221. A hydraulic cylinder is fixed on each of the five groups of second support plates 222.
[0030] Specifically, a heat-insulating and anti-skid pad is fixed on the lower side of the limiting and compacting plate 223 to prevent the limiting and compacting plate 223 from being in a high-temperature state for a long time, which affects the service life of the limiting and compacting plate 223;
[0031] In the above scheme, with the assistance of the hydraulic cylinder on the second support plate 222, the limiting and compacting plate 223 is driven downward by the hydraulic rod. The limiting and compacting plate 223 moves downward and pressurizes and fixes the boiler body 11 and the top cover 15, thereby ensuring the sealing of the boiler body 11 and the top cover 15.
[0032] Working principle: When using the easily replaceable boiler seal, connect the external power supply, quickly replace the seal inside the boiler by setting the limit adjustment structure 2, and seal the boiler with the assistance of the rotating seal assembly 1.
