One end of the first feeding pipe 21 is inserted into the feeding hole, and the other end extends out of the feeding hole. The feeding port 211 is located on the side of the feeding pipe extending out of the feeding hole near the two filter cloths. The cloth plate 22 is fixedly connected to the side of the first feeding pipe 21 near the two filter cloths and extends between the two filter cloths.
