[0023] The housing 1 is provided with an air inlet 2, an air outlet 3, several discharge ports 5 corresponding to the packing area 10, and two sets of air passages 11. The packing area 10 is provided with two sets of air passages side by side, with a gap between the two sets. The two sets of air passages 11 are respectively located near the air inlet 2 and the air outlet 3.

[0024] The material feeding and maintenance port 4 is located on the housing 1 and communicates with the packing area 10 inside the housing 1, such as Figure 2 The feeding and maintenance port 4 is set along the entire length of the box body 1, and one feeding and maintenance port 4 corresponds to one filling area 10.

[0025] like Figure 4 A filter screen 7 and a side sealing plate 9 are respectively installed around the packing area 10. Several sets of filter screens 7 are set along the length of the packing area 10 (from the air inlet 2 to the air outlet 3 of the equipment), thereby reducing the size of a single set of filter screens 7 and making it easier to disassemble during installation and maintenance.

[0026] like Figure 5 The filter screen mounting body 8 is set in the housing 1. The filter screen mounting body 8 adopts a stainless steel U-shaped slide.
