An external feeding pipe 11 is installed on the outside of the intermediate pipe 4, and a third connecting flange 12 is fixed on both sides of the external feeding pipe 11. The valve pipe 2 and the intermediate pipe 4 on both sides of the conveying valve body 1 are flanged together by the first connecting flange 3 and the second connecting flange 6. Similarly, the intermediate pipe 4 and the external feeding pipe 11 are flanged together by the second connecting flange 6 and the third connecting flange 12. This connection structure allows the intermediate pipe 4 to be disassembled and maintained. The connecting inner pipe 8 is slidably installed inside the intermediate pipe 4 through the sliding fit between the alignment protrusion 10 and the alignment groove 7, so that the connecting inner pipe 8 and its internal filter assembly 9 can be disassembled and cleaned.

[0016] like Figure 1 and Figure 3As shown, a filter assembly 9 is installed inside the connecting inner tube 8. The filter assembly 9 includes a rotating shaft 901, a filter screen 902, a sealing rubber ring 903, a motor shaft 904, a steering motor 905, and a baffle frame 906. The filter screen 902 is rotatably connected to the inside of the connecting inner tube 8 via the rotating shaft 901. A sealing rubber ring 903 is provided on the outer side of the filter screen 902. One end of the rotating shaft 901 is connected to the motor shaft 904. A steering motor 905 is installed on the outer side of the steering motor 904.

The filter screen 902 has a circular structure, and three filter screens 902 are evenly spaced. The alignment protrusion 10 and the alignment groove 7 are slidably connected. At the same time, the size of the baffle frame 906 is the same as the size of the protrusion 5. The double-layer structure connecting the inner tube 8 and the intermediate tube 4 enhances structural strength, protects the internal filter screen 902, and reduces deformation, avoiding the problem of filter screen 902 failing to function properly due to tube deformation. The baffle frame 906 has a closed structure, which is convenient to be installed inside the convex frame 5.
