[0032] Please refer to Figure 1 、 Figure 2 and Figure 3 the outer surfaces of each first base 304 and each second base 305 are rotatably connected with a mounting block 306, the inner wall of each mounting block 306 is provided with a plurality of positioning pins 307, the other assemblies can be conveniently positioned and installed in the inner wall of the mounting block 306 through the positioning pins 307, the shell 1 is provided with a plurality of filter cloth bodies 308 corresponding to the first bases 304, the two sides of each filter cloth body 308 are provided with uniformly distributed positioning holes 309, the positioning holes 309 are matched with the positioning pins 307, the filter cloth bodies 308 can be conveniently installed between the corresponding first bases 304 and second bases 305 through the positioning holes 309 and the positioning pins 307, and the filter cloth bodies 308 can also be conveniently replaced through the positioning pins 307.

[0033] It needs to be explained that a first base 304, a second base 305 and a filter cloth body 308 can be regarded as a group. When the first servo motor 301 starts, it will drive the threaded rod 302 to rotate. Through the rotation of the threaded rod 302, the first base 304 can be moved, while the corresponding second base 305 cannot be moved.

The outer surface of the air inlet 401 is fixedly connected with a second servo motor 406. The output shaft end of the second servo motor 406 is fixedly connected with the rotating shaft end of the reciprocating screw rod 405. When the second servo motor 406 starts, it will drive the corresponding reciprocating screw rod 405 to rotate.

The air inlet assembly 4 can make the hot air continuously transported in different directions, so that the hot air can be uniformly transported into the shell 1, avoiding the influence of the evaporation filtration effect caused by the fact that the edge area inside the shell 1 cannot receive the action of hot air. When the second servo motor 406 starts, the connecting block 404 can reciprocate along the reciprocating screw rod 405. When the connecting block 404 reciprocates, the plurality of blades 403 can simultaneously reciprocate, and the hot air can be uniformly transported to the inner wall of the shell 1 for evaporation filtration.
