[0035] Working principle: When in use, firstly, the material to be stirred is passed through the conical mouth 3 and the feed port 4 into the inner cylinder 6, and then the driving motor 1 is started to rotate to drive the connecting shaft 2 to rotate. The rotation of the connecting shaft 2 can drive the stirring blade 16 and the stirring rod 17 to rotate.

When the pull rod 13 slides out of the filter 24, the filter 24 can be taken out. When the filter 24 is taken out, the pull rod 13 can be released. At this time, the pull rod 13 will shrink due to the elastic force of the spring 27 and return to its original position. When the push block 28 is against the telescopic shell 11, the pull rod 13 stops moving and is fixed, thereby realizing the disassembly of the filter 24.
