A scraper 20 is fixedly connected to the surface of the stirring shaft 18, and one end of the scraper 20 close to the dryer shell 2 is in contact with the dryer shell 2.

[0035] The drying component is arranged above the base 1, and the drying component includes a fan cover 3, which is fixedly connected to the upper end of the base 1, a fan 21 is fixedly installed inside the fan cover 3, a heating wire 22 is fixedly connected inside the fan cover 3, an air intake pipe 7 is fixedly connected to the upper end of the fan cover 3, and the end of the air intake pipe 7 away from the fan cover 3 is connected to the connecting pipe 6 by a rotating joint, an air intake pipe 2 16 is fixedly connected to the inner wall of the dryer shell 2, the shape of the air intake pipe 2 16 is spiral, the air intake pipe 2 16 is fixedly connected to the connecting pipe 6, and a plurality of ventilation holes 15 are evenly arranged on the bottom surface of the dryer shell 2.

[0036] The inner wall of the dryer shell 2 is a hollow structure, the interiors of the air inlet pipe 16, the connecting pipe 6 and the air inlet pipe 1 7 are interconnected, the air inlet pipe 16 is connected to the hollow part inside the dryer shell 2, and the multiple ventilation holes 15 are respectively connected to the interior of the dryer shell 2 and the hollow part inside the dryer shell 2.

[0037] The upper end of the dryer shell 2 is fixedly connected with an inlet 8 and an exhaust pipe 11, the lower end of the dryer shell 2 is fixedly connected with an outlet 9, and the lower end of the dryer shell 2 is fixedly connected with a protective shell 17 by bolts.

[0038] When the device is used, the material to be dried is first added into the dryer shell 2 from the feed port 8, and then the fan 21 and the heating wire 22 are started to heat the air and the heated air is passed from the air inlet pipe 1 7, the connecting pipe 6 and the air inlet pipe 2 16 into the cavity of the inner wall of the dryer shell 2, and then passed into the interior of the dryer shell 2 from the ventilation hole 15 to heat and dry the material.

[0043] The heat is transferred to the inner wall of the dryer shell 2 through the hot air, and the hot air is passed into the interior of the dryer shell 2 through the ventilation holes 15, so that the inner wall of the dryer shell 2 and the hot air transfer the heat to the material, thereby improving the heat transfer effect, improving the heating effect of the device, facilitating the heating and drying of the material, and improving the drying efficiency.

[0044] Working principle: When using the device, first add the material to be dried into the dryer shell 2 from the feed port 8, then start the fan 21 and the heating wire 22 to heat the air and pass the heated air from the air inlet pipe 1 7, the connecting pipe 6 and the air inlet pipe 2 16 into the cavity on the inner wall of the dryer shell 2, and pass the heated air into the interior of the dryer shell 2 from the ventilation hole 15 to heat and dry the material.

[0045] Since the heated air transfers heat to the air inlet pipe 16, the air inlet pipe 16 transfers the heat to the inner wall of the dryer shell 2, so that the inner wall of the dryer shell 2 is heated, it is convenient to cooperate with the hot air ejected from the ventilation hole 15 to heat and dry the material, thereby improving the drying effect.

[0046] While heating and drying the material inside the dryer shell 2, the driving motor 10 is started to drive the stirring shaft 18 to rotate, and the stirring shaft 18 drives the stirring rod 19 and the scraper 20 to rotate. The stirring rod 19 stirs the material inside the dryer shell 2, and the scraper 20 scrapes the material at the bottom of the dryer shell 2 to prevent the material from blocking the ventilation hole 15 and affecting the heating and drying of the material. In the process of stirring the material, the driving motor 2 is started to drive the worm 13 to rotate, the worm 13 drives the worm wheel 14 to rotate, the worm wheel 14 drives the rotating shaft 5 to rotate, the rotating shaft 5 drives the dryer shell 2 to rotate, and the dryer shell 2 drives the connecting pipe 6 to rotate. The reciprocating rotation of the dryer shell 2 facilitates the stirring of the material in the dryer shell 2, prevents the material at the bottom of the dryer shell 2 from staying at the bottom, improves the distribution of the material, and makes the material more evenly heated, thereby accelerating the evaporation and drying process of the water, and then the water evaporates and is discharged from the exhaust pipe 11, and when the material is dried, it is discharged from the discharge port 9.

[0047] When the ventilation hole 15 is clogged during long-term use, the bolts connecting the protective shell 17 and the dryer shell 2 are removed to facilitate the removal of the protective shell 17, the ventilation hole 15 is cleaned, and the service life of the device is extended.
