[0020] As Figure 1-7As shown in the figure, the utility model provides a yellow phosphorus filtering device, which includes a filter cylinder body 1 and a filter cylinder cover 2 fixedly connected to the filter cylinder body 1. A filter plate 5 is installed at the top inside the filter cylinder body 1. A powder sintered tube 3 is connected to the filter plate 5. A yellow phosphorus inlet pipe 6 and a yellow phosphorus outlet pipe 7 are respectively connected to the bottom and top of the side wall of the filter cylinder body 1.
