The other end of the push rod 18 penetrates the upper wall of the inner cavity of the fixed cylinder 16 and extends outside the wall. The top end of the push rod 18 is fixedly connected to the fixed plate frame 7. When the cylinder 8 drives the fixed plate frame 7 to reciprocate up and down, it can also drive the push rod 18 to reciprocate up and down, thereby driving the movable piston 17 to reciprocate up and down.

[0045] An output air pipe 21 and an input air pipe 22 are fixedly connected to the bottom side of the inner cavity of the fixed cylinder 16, and check valves are installed on the output air pipe 21 and the input air pipe 22. One end of the output air pipe 21 extends to the lower side of the inner cavity of the outer sleeve 10, and one end of the input air pipe 22 extends to the upper side of the inner cavity of the outer sleeve 10.

When the movable piston 17 moves upward, the gas on the upper side of the inner cavity of the outer sleeve 10 can be sucked through the input air pipe 22, so that the inner cavity of the inner cylinder 11 The gas flows to the upper side of the inner cavity of the outer sleeve 10 through the second air hole 15, and the circulating flow of the gas inside the inner cylinder 11 is realized by the continuous up and down reciprocating motion of the movable piston 17, so that the hot air heating and drying can be played, making the drying more thorough and uniform; the inner cavity of the fixed cylinder 16 is provided with activated carbon particles 20, and the inner cavity wall of the fixed cylinder 16 is fixedly connected with a mesh plate 19.

A plurality of rubber protrusions 30 are fixedly connected to the arc-shaped wall of the circular block 29. The front ends of the plurality of rubber protrusions 30 A rigid column 31 is fixedly arranged at each place. When the inner cylinder 11 rotates back and forth to heat and dry the modified plastic particles inside, the back and forth rotation of the inner cylinder 11 can make the internal circular block 29 swing back and forth, so that the swinging circular block 29 contacts and collides with the modified plastic particles, and the back and forth swing of the swing rod 25 can also make the movable rod 26 swing back and forth, so that in conjunction with the setting of the connecting spring 27, the movable rod 26 can vibrate up and down after contacting and colliding with the plastic particles, driving the circular block 29 to vibrate up and down, so that the rigid column 31 on the circular block 29 can vibrate, so that the contact with the modified plastic particles can fully break up the modified plastic particles, avoiding the problem of uneven drying caused by adhesion between the modified plastic particles.
