[0002] A dryer refers to a mechanical device that uses heat energy to reduce the moisture of materials, and is used for drying operations on objects. The dryer makes the moisture, generally water or other volatile liquid components, in the materials vaporize and escape by heating, so as to obtain solid materials with a specified moisture content.

[0003] According to the related technology in the above, the present inventor believes that the existing dryers rely on two single structure forms of connecting rods and scattering rods to stir the materials. The internal space of the tank is large, and there are areas that cannot be reached by the stirring shaft and the scattering rod. The materials in these blind areas are easily accumulated due to the action of the centrifugal force in a single direction, resulting in poor uniformity of the materials. In this way, the heat cannot fully contact with the accumulated materials, thereby greatly reducing the drying efficiency and the mixing uniformity level.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it can include prior art known by those skilled in the art. CONTENT OF THE UTILITY MODEL

[0023] The application embodiment discloses a double-cone rotary vacuum dryer. Referring to Figs. 1-3 A double-cone rotary vacuum dryer comprises:

[0024] The bottom plate 5 is provided with a supporting mechanism, and the vacuum dryer body 1 is installed in the supporting mechanism. The vacuum dryer body 1 is provided with a stirring mechanism. The stirring mechanism is used for fully stirring the material, thereby improving the drying efficiency and the mixing uniformity.

[0025] The stirring mechanism comprises rotating shafts 7 which are rotatably connected between the left and right inner walls of the vacuum dryer body 1. A plurality of stirring rods 8 are fixedly connected to each rotating shaft 7. Two sliding cavities 11 are formed in each stirring rod 8. Telescopic rods 9 are slidably connected between the left and right inner walls of the two sliding cavities 11. One end of each telescopic rod 9 is elastically connected to the inner wall of the corresponding sliding cavity 11 through a connecting spring 12. A plurality of stirring plates 10 are fixedly connected to each telescopic rod 9 and stirring rod 8.

[0026] The first motor 2 drives the gear 6 above to rotate. Since the two gears 6 are meshed with each other, the two gears 6 drive the corresponding rotating shafts 7 to rotate at the same time. When the two rotating shafts 7 rotate, the corresponding multiple stirring rods 8, telescopic rods 9 and stirring plates 10 are driven to rotate, and the material is stirred. Since the gears 6 are used for transmission, the rotating directions of the multiple stirring rods 8, telescopic rods 9 and stirring plates 10 are opposite, so that the stirring effect is better, and the material is mixed uniformly. When the multiple stirring rods 8, telescopic rods 9 and stirring plates 10 rotate, under the elastic action of the multiple connecting springs 12, the multiple telescopic rods 9 and stirring plates 10 are shaken up and down, so that the material is fully stirred, the diffusion movement of the material in the vacuum dryer body 1 is further driven, the material is fully stirred, and the drying efficiency and the mixing uniformity are improved.

[0027] The transmission mechanism comprises a rectangular block 3 mounted on the right outer wall of the vacuum dryer body 1. The first motor 2 is mounted on the right side of the rectangular block 3. Two gears 6 are arranged in the rectangular block 3. The two gears 6 are meshed with each other. One end of each of the two rotating shafts 7 extends into the rectangular block 3 and is fixedly connected with the corresponding gear 6. The output shaft of the first motor 2 is fixedly connected with one end of the rotating shaft 7 above.

[0028] Referring to Fig. 1 The supporting mechanism comprises two vertical plates 4 fixedly connected on the upper end of the bottom plate 5.

Subsequently, the first motor 2 is started.

[0031] The first motor 2 drives the gear 6 above to rotate. Since the two gears 6 are meshed with each other, the two gears 6 drive the corresponding rotating shafts 7 to rotate at the same time. When the two rotating shafts 7 rotate, the corresponding multiple stirring rods 8, telescopic rods 9 and stirring plates 10 are driven to rotate, and the material is stirred. Since the gears 6 are used for transmission, the rotating directions of the multiple stirring rods 8, telescopic rods 9 and stirring plates 10 are opposite, so that the stirring effect is better, and the material is mixed uniformly.

[0032] It is worth mentioning that, when the stirring rod 8, the telescopic rod 9 and the stirring plate 10 rotate, the telescopic rod 9 and the stirring plate 10 will be shaken up and down under the elastic action of the connecting spring 12, so that the material can be fully stirred, the diffusion movement of the material in the vacuum dryer body 1 is further driven, the material is fully stirred, and the drying efficiency and the mixing uniformity level are improved.
