[0049] Example 2

[0050] Reference Figure 1-11The difference between this embodiment and embodiment 1 is that a transmission bin 105 is provided in the lower barrel 3, and an adjusting shaft 9 is rotatably provided in the transmission bin 105. The adjusting shaft 9 is provided with a gear column 91 meshing and matching with the arc-shaped toothed plate 81.

As the adjusting motor 11 is turned on, its output shaft can drive the gear set inside the synchronous box 10 to adjust the adjusting shafts 9 located on both sides of the lower barrel 3 to rotate synchronously in opposite directions, so as to allow the gear column 91 to mesh and match with the arc-shaped toothed plate 81, so that the arc-shaped closing plate 8 can be opened and closed synchronously.

[0051] For other structures not described, refer to Example 1.

[0052] Example 3

[0053] Reference Figure 1-11 The difference between this embodiment and embodiment 1 is that a straight rack 605 is provided at the end of the scraper bar 604, and a stirring mechanism 7 is provided on the rake blade 51. The stirring mechanism 7 includes a rotating shaft 701 rotatably connected to the rake blade 51. When the adjustment block 603 drives the scraper bar 604 to move on the surface of the rake blade 51 according to the shape of the fin 21, the scraper bar 604 can drive the straight rack 605 to move synchronously.

[0054] Specifically, a spur gear 702 meshing with the spur rack 605 is provided at the end of the rotating shaft 701, and a blade 703 for stirring the material is also provided on the rotating shaft 701. When the spur rack 605 moves, the spur gear 702 can mesh with it, so that the spur gear 702 can drive the rotating shaft 701 to rotate, so that when the rake blade 51 moves, the rotating shaft 701 can synchronously drive the blade 703 to act on the material, so as to improve the stirring efficiency of the material inside the drying drum 1, thereby improving the drying efficiency of the material.

[0055] For other structures not described, refer to Example 1.

[0056] Working principle: In the present invention, firstly, the interior of the drying cylinder 1 is vacuumed by an external vacuuming device, and then the solid materials after filtering are passed into the interior of the drying cylinder 1 through the feeding pipe 101, and then the output shaft of the main motor 41 is turned on to drive the main shaft 4 to rotate inside the drying cylinder 1, so that the mounting frame 401 drives the rake leaves 51 to rotate inside the drying cylinder 1 through the tie rod 5, so that the rake leaves 51 stir and scatter the materials inside the drying cylinder 1;

[0057] When the rake blade 51 rotates with the mounting frame 401 through the tie rod 5, the position of the rake blade 51 is adapted to move through the cooperation and limiting effect of the guide column 512 and the guide groove 201, and the surface of the fin 21 is cleaned through the slot 511 at the same time, so that the adhesion does not affect the thickness of the fin 21, thereby avoiding the situation that the heat transfer efficiency of the fin 21 is reduced;

[0058] As the rake blade 51 moves, the bottom end of the adjustment block 603 is always in contact with the top end of the fin 21, so that the extension rod 601 can be adjusted in position inside the tie rod 5. When the adjustment block 603 moves to the top end of the track of the fin 21, the return spring 602 is in a fully compressed state. When the adjustment block 603 is at the bottom end of the track of the fin 21, the return spring 602 is in a fully released state, so that the adjustment block 603 is always in contact with the top end of the fin 21.

[0059] When the adjusting block 603 moves back and forth following the shape of the fin 21, the scraper bar 604 can act on the surface of the rake blade 51, so that the scraper bar 604 cleans the adhesion on the surface of the rake blade 51, and simultaneously drives the spur rack 605 to move back and forth;

[0060] When the spur rack 605 moves, the spur gear 702 can mesh with it, so that the spur gear 702 can drive the rotating shaft 701 to rotate, so that the blade 703 can assist the rake blade 51 in stirring the material, thereby achieving a synergistic effect and improving the stirring efficiency of the material.

[0061] After the material inside the drying cylinder 1 is dried, the adjusting motor 11 is turned on, and the output shaft of the adjusting motor 11 cooperates with the gear set inside the synchronous box 10 to drive the two adjusting shafts 9 to rotate synchronously in opposite directions, so that the gear column 91 can mesh with the arc-shaped toothed plate 81, so that the arc-shaped closing plate 8 can open its closure for the discharge port 103. Under the pushing and stirring action of the rake leaves 51 and the blades 703, the opened discharge port 103 can meet the passage of materials, so that the materials can enter the interior of the discharge cylinder 3. When the arc-shaped closing plate 8 is opened, the discharge motor 311 is synchronously turned on to drive the auger shaft 31 to act on the materials that fall into the interior of the discharge cylinder 3, and the materials are discharged through the discharge pipe 102 and collected centrally.
