By rotating the rotating shaft 13, the rotating disk 9 is rotated on one side of the fixed disk 8. A plurality of sliding rods 21 respectively move along the inner wall of each special-shaped groove 20, and the fixing rod 19 moves in the fixed disk 8 until one end of the fixing rod 19 is moved out from the inside of the mounting groove 18, thereby releasing the restriction of the disassembly cover 2. The cooperation between the special-shaped groove 20 and the fixing rod 19 can quickly remove the disassembly cover 2 from the protective shell 1, thereby improving the catalyst replacement efficiency and the surface cleaning efficiency of the porous ceramic filter element 10.

[0021] like Figure 2 - Figure 4 As shown, a plurality of sealing grooves 16 are provided at the upper end of the protective shell 1, and a plurality of sealing rings 17 are fixedly connected to the lower end of the disassembly cover 2 near the edge. The outer walls of the plurality of sealing rings 17 are respectively engaged with the inner walls of the plurality of sealing grooves 16. Through the cooperation between the sealing rings 17 and the sealing grooves 16, a labyrinth seal is formed between the disassembly cover 2 and the protective shell 1 to prevent wastewater leakage and affect the environment.

[0022] like Figure 1 - Figure 4As shown, the middle part of the upper end of the disassembly cover 2 is fixedly connected to the limiting snap ring 6, and one end of the rotating shaft 13 is fixedly connected to the hexagonal connecting rod 15. The outer wall of the hexagonal connecting rod 15 is slidably connected to the limiting ring 7, and one side of the outer wall of the limiting ring 7 is clamped with the inner wall of the limiting snap ring 6. When the disassembly cover 2 is installed on the protective shell 1, the limiting ring 7 is pressed downward, and the inner wall of the limiting ring 7 slides along the hexagonal connecting rod 15. The outer wall of the limiting ring 7 is clamped in the limiting snap ring 6, thereby fixing the hexagonal connecting rod 15 to prevent the staff from accidentally touching the hexagonal connecting rod 15 and affecting the sealing performance of the sealing ring 17 and the sealing groove 16.

The wastewater is then filtered through the porous ceramic filter element 10. When the filter device is used for a long time and the catalyst needs to be added, the limiting ring 7 is pulled and the limiting ring 7 is taken out from the limiting clamp 6 from the side of the outer wall. When the limiting ring 7 is rotated, the rotating disk 9 rotates on one side of the fixed disk 8. A plurality of sliding rods 21 respectively move along the inner wall of each special-shaped groove 20, and the fixed rod 19 moves in the fixed disk 8 until When one end of the fixing rod 19 is moved out from the inside of the mounting groove 18, the restriction of the disassembly cover 2 is released, and the disassembly cover 2 is removed from the protective shell 1. Then, the porous ceramic filter element 10 is rotated by the handle 11 to remove the porous ceramic filter element 10 from the mounting bracket 12. While taking out the porous ceramic filter element 10, the surface of the porous ceramic filter element 10 is cleaned, and the catalyst is added to the upper end of the mounting bracket 12. After the addition is completed, the porous ceramic filter element 10 is fixed on the mounting bracket 12, and the disassembly cover 2 is covered on the protective shell 1. The rotating shaft 13 is rotated in the opposite direction so that the fixing rod 19 is stuck in the mounting groove 18, thereby completing the replacement of the porous ceramic filter device.
