Technical Field

[0001] This utility model relates to the field of boiler equipment technology, specifically to a mechanical sealing structure between a boiler and a slag well. Background Technology

[0002] During boiler operation, the seal between the boiler and the slag well is crucial. Traditional water seal structures require continuous water supply to maintain the sealing effect, which not only consumes a lot of water resources but also increases equipment operating costs and maintenance workload. Moreover, the water seal plate is easily corroded by being immersed in the water seal tank for a long time, which leads to a decrease in sealing performance and even leakage, affecting the normal operation and safety of the boiler. Therefore, this utility model proposes a mechanical seal structure between the boiler and the slag well to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a mechanical sealing structure between the boiler and the slag well to solve the problems mentioned in the background art.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1 to 6 This utility model provides a technical solution: a mechanical seal structure between a boiler and a slag well, including a fixing plate 1, an upper connecting plate 2 fixedly installed on the side of the fixing plate 1, an installation ring 3 fixedly installed on the top of the upper connecting plate 2, a clamping groove 4 opened on the outer side of the installation ring 3, and a clamping plate 5 slidably sleeved on the side of the clamping groove 4, an anti-detachment groove 6 opened on the outer side of the installation ring 3, and an anti-detachment plate 7 slidably sleeved on the side of the anti-detachment groove 6, and high-temperature resistant ceramic fiber cloth 8 installed on the top and bottom of the anti-detachment plate 7. The top of the anti-detachment plate 7 is provided with a sliding groove 9, and the side of the sliding groove 9 is slidably equipped with a first movable plate 10 and a second movable plate 11. The top of the first movable plate 10 is provided with a trapezoidal groove 12, and the first movable plate 10 is slidably connected to the second movable plate 11 through the trapezoidal groove 12. The bottom of the first movable plate 10 is provided with an anti-detachment tooth 13, the top of the second movable plate 11 is provided with an anti-detachment tooth 13, and the anti-detachment tooth 13 is tightly connected to the high temperature resistant ceramic fiber cloth 8. The bottom of the first movable plate 10 is provided with an anti-detachment tooth 13.

[0020] A limiting block 14 is provided on the side of the slide groove 9, and the limiting block 14 slides in cooperation with the first movable plate 10 and the second movable plate 11. The length of the anti-detachment teeth 13 of the first movable plate 10 and the second movable plate 11 is greater than that of the slide groove 9, and the anti-detachment teeth 13 of the second movable plate 11 and the first movable plate 10 contact the top and bottom of the anti-detachment plate 7. The first movable plate 10 and the second movable plate 11 slide in a trapezoidal manner, and are clamped and connected to the double-layer high-temperature resistant ceramic fiber cloth 8 by the anti-detachment teeth 13. When the high-temperature resistant ceramic fiber cloth 8 is pulled, the anti-detachment teeth 13 can drive the first movable plate 10 or the second movable plate 11 to move. Then, the relative set of movable plates is pushed by the trapezoidal groove 12, which tightly clamps the high-temperature resistant ceramic fiber cloth 8 and achieves a self-sealing effect.

[0021] The mounting ring 3, clamping plate 5, anti-detachment plate 7, first movable plate 10 and second movable plate 11 constitute an anti-detachment component. The bottom of the high-temperature resistant ceramic fiber cloth is fixedly connected to the lower connecting plate 15, and the top of the lower connecting plate 15 is also provided with an anti-detachment component. The anti-detachment teeth 13 can improve the overall connection effect between the high-temperature resistant ceramic fiber cloth 8 and the connecting part, play an anti-detachment function, and ensure the sealing quality of the installation.

[0022] The bottom of the lower connecting plate 15 is welded to a slag well 16, and the top of the clamping plate 5, the anti-detachment plate 7, the first movable plate 10 and the second movable plate 11 are all provided with threaded holes 17.

[0023] A fastening bolt 18 is inserted into the threaded hole 17. The nut on the top of the fastening bolt 18 contacts and engages with the clamping plate 5. Through the connection between the threaded hole 17 and the fastening bolt 18, the fastening bolt 18 clamps and seals the high-temperature resistant ceramic fiber cloth with the clamping plate 5, making the installation and replacement of the sealing component more convenient and quick, and reducing the maintenance difficulty and workload.

[0024] The bottom of the clamping plate 5 is provided with anti-detachment teeth 13, and the bottom of the clamping plate 5 is equipped with a sealing ring 19. The sealing ring 19 is sleeved on the side of the clamping groove 4. The sealing ring 19 is in close contact with the top of the high temperature resistant ceramic fiber cloth 8. The sealing ring 19 is subjected to the downward pressure of the clamping plate 5 and is located between the anti-detachment plate 7 and the clamping plate 5, thereby enhancing the sealing effect of the structure.

[0025] In practical use: First, install the upper connecting plate 2 at the lower end of the boiler water-cooled wall, ensuring that the installation is firm and the position is accurate. Then, weld the lower connecting plate 15 to the upper end of the slag well 16, ensuring the installation quality. Next, insert multiple layers of high-temperature resistant ceramic fiber cloth 8 into the top and bottom of the anti-detachment plate 7. The anti-detachment teeth 13 can improve the overall connection effect between the high-temperature resistant ceramic fiber cloth 8 and the anti-detachment plate 7, playing an anti-detachment function and ensuring the sealing quality of the installation. Finally, through the connection method of threaded hole 17 and fastening bolt 18, the fastening bolt 18 will push the clamping plate 5 to clamp and seal the high-temperature resistant ceramic fiber cloth 8. The structure is simple, making the installation and replacement of the sealing component more convenient and quick, reducing the maintenance difficulty and workload. When the boiler is running, high-temperature flue gas and slag are discharged through the slag well. The high-temperature resistant ceramic fiber cloth in the sealing component can effectively block the leakage of high-temperature flue gas and dust.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
