It should be understood that the specific embodiments described herein are part of the embodiments of the utility model, rather than all the embodiments, and are only used to explain the embodiments of the utility model, not to limit the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a chain wheel sealing detection device for a scraper slag extractor, comprising: a base 1 and a main shaft 7. One end of the base 1 is fixedly installed with a bearing box 2. A bearing is provided inside the bearing box 2. One end of the bearing box 2 is fixedly installed with a first sealing gasket 3, and is fixedly installed on one side of the base 1 through screws. The first sealing gasket 3 is in close contact with one end of the base 1, sealing and fixing the bearing box 2 on one side of the base 1. One end of the bearing box 2 away from the base 1 is fixedly installed with a sealing shell 4. A hole for the main shaft 7 to pass through is provided on one side of the bearing box 2 away from the base 1. One end of the sealing shell 4 is fixedly installed with a second sealing gasket 5, and is fixedly installed on one side of the bearing box 2 through screws. The second sealing gasket 5 is in close contact with one end of the bearing box 2, sealing and fixing the sealing shell 4 on the outer wall of one end of the bearing box 2. The sealing shell 4 is made of aluminum alloy. The static sealing of the second sealing gasket 5 of the sealing shell 4 replaces the original dynamic sealing, improving the sealing performance and no longer leaking. A magnetic sensor 6 is provided on the sealing shell 4, which is installed at a position corresponding to the magnet 10. When the main shaft 7 rotates, the magnet 10 also rotates accordingly. When the magnet 10 rotates one circle, the magnetic sensor 6 measures a signal and transmits the signal to the DCS system of the central control room. Automatic system detection is realized, eliminating the need for manual inspection.

[0024] One end of the main shaft 7 is fixedly installed with a chain wheel 8. A sealing component is provided at the connection between the main shaft 7 and the base 1. One end of the main shaft 7 away from the chain wheel 8 passes through the centers of the bearing box 2, the bearing, the base 1, and the sealing component, and enters the sealing shell 4. One end of the main shaft 7 away from the chain wheel 8 is fixedly installed with a bracket 9. One end of the bracket 9 is fixedly connected to the magnet 10.

[0025] The sealing component includes a sealing plate 11. The sealing plate 11 is hermetically connected to the side wall of one end of the base 1 away from the bearing box 2 through screws and a third sealing gasket 12. By tightening the screws, the third sealing gasket 12 is in close contact with the base 1, thereby sealing the sealing plate 11 at the outer end of the base 1. A sealing cavity 13 is provided at the center of the outer end of the sealing plate 11. A sealing bearing 14 is placed inside the sealing cavity 13. The inner wall of the sealing bearing 14 is fixedly sleeved on the outer wall of the main shaft 7. A fourth sealing gasket 15 and a pressing plate 16 are provided at the outer end of the sealing bearing 14. A number of threaded holes are evenly provided on the inner side wall of the inner end of the sealing bearing 14 and the outer wall of the sealing plate 11. A number of round holes are evenly provided on the side walls of the fourth sealing gasket 15 and the pressing plate 16. Screws pass through the round holes and are threadedly connected to the inner walls of the threaded holes, allowing the fourth sealing gasket 15 to seal the sealing cavity 13 and the sealing bearing 14.

[0026] When the main shaft 7 rotates, the magnet 10 also rotates accordingly. When the magnet 10 rotates one circle, the magnetic sensor 6 measures a signal and transmits the signal to the DCS system of the central control room, realizing automatic system detection and eliminating the need for manual inspection.

[0027] When the device is working, the bearing box 2 and the sealing housing 4 can be filled with lubricating oil and there will be no more leakage, which extends the operation time. A magnetic sensor 6 is provided on the sealing housing 4 and is installed at a position corresponding to the magnet 10. When the main shaft 7 rotates, the magnet 10 also rotates accordingly. When the magnet 10 rotates one circle, the magnetic sensor 6 measures a signal and transmits the signal to the DCS system in the central control room, realizing automatic system detection and eliminating the need for manual inspection tours.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
