[0023] The automatic adjustment device 2 is composed of a sliding rod 201, an annular column 202, a floating plate 203, a frustum-shaped block 204, and a conical block 205. The sliding rod 201 is fixedly installed inside the storage box 1. The annular column 202 is slidably installed on the surface of the sliding rod 201. The sliding rods 201 are arranged in a circular array inside the storage box 1. An annular groove matching the annular column 202 is provided inside the storage box 1.

The floating plate 203 is fixedly installed inside the annular column 202. The frustum-shaped block 204 is fixedly installed on the top of the floating plate 203. Through holes are provided through the surface of the floating plate 203. Grooves are provided on the surface of the frustum-shaped block 204, and the grooves correspond to the through holes. This setting can introduce chemicals into the through holes through the grooves, enabling the chemicals to flow to the bottom of the floating plate 203 more quickly. The conical block 205 is fixedly installed on the top of the frustum-shaped block 204. The conical block 205 is located at the center of the top of the frustum-shaped block 204. The setting of the conical block 205 can observe the amount of chemicals added in real time and prevent chemical spills.

[0024] The stabilizing device 4 is composed of a first annular sleeve 401, a first rotating shaft 402, a second annular sleeve 403, a second rotating shaft 404, and a sleeve 405. The sleeve 405 is sleeved outside the protective sleeve 3. The second rotating shaft 404 is rotatably installed inside the sleeve 405.
