The side wall of the rotary joint 1 is provided with a protective mechanism 2, and the protective mechanism 2 can provide a certain protection for the side filter plate 301.

[0034] Reference Figure 4 and Figure 5 The top of the sleeve 304 is provided with a positioning groove 307, and the outer wall of the clamping block 309 is inserted into the inner wall of the positioning groove 307. There are two groups of positioning grooves 307, and the two groups are arranged at 90 degrees. The diameter of the sleeve 304 is larger than the clamping column 305, and the outer wall of the clamping column 305 is inserted into the inner wall of the sleeve 304. The two groups of filter plates 301 can be connected by clamping the two, so as to achieve the purpose of quick installation and disassembly.
