As shown in fig. 4 to 13, a guide rail is respectively disposed on one side opposite to the first end cover 21 and the second end cover 22, two guide rails are disposed correspondingly, two ends of the rotating shaft 48 are respectively slidably connected with the two guide rails, the guide rail is a closed loop as a whole, and the guide rail on the first end cover 21 is exemplified by a first track 51, a second track 52, a third track 53 and a fourth track 54 which are sequentially connected in a clockwise direction, wherein the second track 52 is located above the shaft lever 14, and the feed port 210 is located between the second track 52 and the shaft lever 14.

The first track 51 is arc-shaped and is coaxially arranged with the shaft lever 14, the central angle corresponding to the first track 51 is 210 degrees, the first track 51 is distributed on the left side edge and the lower side edge of the first end cover 21, when the shaft lever 14 drives the tank body 20 to rotate and then drives the rotating shaft 48 to slide to the first track 51, two telescopic units in the drying assembly 40 are in a fully extended state, the fluidization cloth 49 is in an extended state at the same time, high-temperature drying gas in the ventilation cavity can enter the tank body 20, and a containing groove is formed between two adjacent drying assemblies 40 on the first track 51.

The second rail 52 is integrally arc-shaped and is distributed on the upper side edge of the first end cover 21, and the distance between the second rail 52 and the axis of the shaft 14 is gradually increased in the process of extending in the clockwise direction, so that when the rotating shaft 48 moves on the second rail 52 in the clockwise direction, the two telescopic units in the drying assembly 40 are gradually contracted, so that the third plate 43 is gradually contracted in the first plate 41, the first ventilation holes 411 and the second ventilation holes 421 are gradually staggered in the process, the third ventilation holes 431 and the fourth ventilation holes 441 are gradually staggered in the process, until the high-temperature drying gas in the ventilation cavity cannot enter the tank 20, and the fluidized cloth 49 is folded in the process.

The third rail 53 extends along the radial direction of the shaft 14 and gradually approaches the shaft 14, so that when the rotating shaft 48 moves from the second rail 52 to the third rail 53, the two telescopic units in the drying assembly 40 are suddenly stretched, that is, the third plate 43 is suddenly stretched out from the first plate 41, during which the material adhered to the fluidization cloth 49 is easily separated from the fluidization cloth 49, so that the phenomenon that the material is hardened on the fluidization cloth 49 is avoided, and it should be noted that when the rotating shaft 48 slides to the end of the second rail 52 closest to the shaft 14, the first ventilation hole 411 and the second ventilation hole 421 are still in a mutually staggered state, and the third ventilation hole 431 and the fourth ventilation hole 441 are still in a mutually staggered state.

The specific working principle is as follows: referring to fig. 1 to 13, firstly, the hydraulic cylinder 11 is controlled to make the whole tank 20 in a horizontal state, then, wet materials to be dried are added into the tank 20 from the feed hopper 211, the wet materials fall into the accommodating groove at the lower part of the first end cover 21, then, the driving motor is controlled to drive the shaft lever 14 to rotate clockwise, and further, the tank 20 is driven to rotate synchronously, the rotating shafts 48 on the drying assemblies 40 can be driven to slide synchronously in the guide rails by the rotation of the tank 20, along with the clockwise rotation of the tank 20, the wet materials at the lower part of the first end cover 21 can move clockwise upwards under the driving of the accommodating groove, in the process, the wet materials at the accommodating groove can gradually fall out from the accommodating groove in the clockwise upwards moving process, and the high-temperature drying gas in the ventilation cavity in the drying assembly 40 corresponding to the first track 51 can be blown to the wet materials in the accommodating groove, so that the wet materials can be lifted up in the tank 20 under the blowing action of the high-temperature drying gas, and further, the wet materials can be uniformly dried and fully dried.

It should be noted that during this process, since the ventilation cavities in the drying assemblies 40 located in the second rail 52, the third rail 53 and the fourth rail 54 are not capable of inputting the high-temperature drying gas into the tank 20, the disturbance of the high-temperature drying gas blown out from the drying assemblies 40 located in the first rail 51 is avoided, which is further beneficial to drying the wet material.

As the can 20 continues to rotate clockwise, a portion of the wet material may adhere to the fluidization cloth 49, and when the drying assembly 40 moves from the second rail 52 to the third rail 53, the third plate 43 suddenly stretches out of the first plate 41 under the action of the first elastic member 45, so that the fluidization cloth 49 rapidly expands, thereby facilitating shaking off the material adhered to the fluidization cloth 49.

Then, as the can 20 continues to rotate clockwise, the drying assembly 40 moves from the third rail 53 to the first rail 51 located at the lower portion of the first end cap 21, and at this time, the first air holes 411 and the second air holes 421 are in corresponding states, the third air holes 431 and the fourth air holes 441 are in corresponding states, and the high-temperature drying gas can enter the accommodating groove through the ventilation cavity and disturb the material particles in the accommodating groove, so that the material can be heated uniformly, thereby being beneficial to accelerating the drying of the material.

After the tank 20 rotates for a plurality of circles, the materials in the tank 20 are sufficiently dried, then the tank 20 is stopped to rotate and the discharge hopper 221 is opened, one end of the tank 20, which is close to the feed hopper 211, is lifted by controlling the hydraulic cylinder 11, and then the materials in the tank 20 can be smoothly discharged through the discharge hopper 221, so that the drying of wet materials is completed.

While embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the invention, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the invention.
