The top of the air inlet 8 passes through the recovery water tank 3 and protrudes upward, and the top of the air inlet 8 is higher than the top of the water outlet 9, so that a height difference is formed between the water inlet end of the water outlet 9 and the air outlet end of the air inlet 8, and the water in the tank does not enter the air inlet 8.

[0028] The inner wall of the water recovery tank 3 is provided with a plurality of slide rail blocks 12 at equal intervals around the axis. The slide rail blocks 12 are all arranged along the axial direction. The pressure plate 5 and the slide rail blocks 12 form limited sliding to facilitate the movement of the pressure plate 5.

[0029] The top of the pressure plate 5 is provided with a plurality of limit blocks 10 at equal intervals around the axis, and the limit blocks 10 correspond to the slide rail blocks 12 one by one. The limit blocks 10 are welded and fixed to the outside of the top of the pressure plate 5. The limit blocks 10 are provided with a slide groove 11 on the side away from the intermediate shaft. The slide groove 11 extends downward through the pressure plate 5. The slide rail blocks 12 are movably embedded in the corresponding slide groove 11, and the pressure plate 5 and the limit blocks 10 form a limited sliding fit with the corresponding slide rail blocks 12 through the slide groove 11, which is convenient for adjusting the position of the pressure plate 5, thereby changing the filamentous filler 4 is in the compressed state, which also makes it easy to open the pressure plate 5 to replace the filamentous filler 4.
