[0036] The inner wall of the reaction chamber 2 is provided with an annular groove, and a rotating ring 11 is installed inside. The outer wall of the rotating ring 11 is slidably connected to the annular groove through a moving ring 12 to ensure that the rotating ring 11 can rotate smoothly. A connecting block 13 is also fixed on the rotating shaft 8. The connecting block 13 is connected to a T-shaped block 15 through a connecting rod 14. The T-shaped block 15 is locked in a retainer 16 inside the rotating ring 11. When the rotating shaft 8 rotates, the rotating ring 11 is driven to rotate through the connecting rod 14. A scraper 17 and a scraper ring 18 are fixed at the bottom of the rotating ring 11. The scraper 17 and the scraper ring 18 abut against the side wall and bottom of the reaction chamber 2, respectively. As the rotating ring 11 rotates, the scraper 17 and the scraper ring 18 can effectively scrape off the adhering substances on the inner wall of the reaction chamber 2.

[0037] When cleaning of reaction chamber 2 is required, control valve 202 is opened, and water enters connecting pipe 203 through inlet pipe 201, then flows into annular pipe 204 through connecting pipe 203, and finally sprays out from nozzles 205 at the bottom of annular pipe 204 to rinse the inner wall of reaction chamber 2. The nozzles 205 are arranged in a circular array centered on the center of annular pipe 204 to ensure uniform rinsing. The scraper 17 and scraper ring 18 effectively remove adhering substances from the inner wall of reaction chamber 2, resulting in better cleaning.
