[0023] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0026] like Figures 1 to 4 The main structure of a raw material drying device shown in the figure is a bottom plate 1 and a drying cylinder 3 for drying chemical raw materials. The top surface of the bottom plate 1 is fixedly connected to the base 2. The drying cylinder 3 is connected and mounted on the top surface of the base 2. The drying cylinder 3 is open at the lower end, and the lower opening of the drying cylinder 3 is connected and sealed to the top surface of the base 2.

[0027] A circular groove 5 is provided on the top surface of the base 2, in which a hollow disk 6 is rotatably mounted. A connecting pipe 7 is provided on the top surface of the hollow disk 6. A plurality of stirring tubes 8 are fixedly connected to the side wall of the connecting pipe 7. The lower end of the connecting pipe 7 is located at the center of the top surface of the hollow disk 6, and the rotation of the hollow disk 6 will drive the connecting pipe 7 to rotate synchronously.

[0028] The top surface of the hollow disk 6 and the outer wall of the stirring tube 8 are connected to and installed with a plurality of air outlet pipes 9 for drying chemical raw materials. A motor 10 is fixedly installed at the bottom of the circular groove 5, and a rotating tube 11 is fixedly connected between the rotating shaft of the motor 10 and the hollow disk 6. The motor 10 drives the rotating tube 11 fixedly connected to the end of the rotating shaft and the hollow disk 6 and the stirring tube 8 connected to the rotating tube 11 to rotate, thereby spraying hot air to the bottom of the chemical raw material through the hollow disk 6, and at the same time spraying hot air to the inside of the chemical raw material through the stirring tube 8 and rotating, thereby accelerating the drying efficiency of the chemical raw material;

[0029] The outer wall of the rotating tube 11 is rotatably sleeved with a sleeve 12. A plurality of air inlet holes are opened on the outer wall of the rotating tube 11, and the air inlet holes are located at the sleeve connection of the sleeve 12. Bearings and sealing rings are symmetrically installed between the inner wall of the sleeve 12 and the outer wall of the rotating tube 11. Thanks to the bearings and sealing rings installed between the inner wall of the sleeve 12 and the outer wall of the rotating tube 11, and the sealing rings are located on the outside of the bearings, the rotating tube 11 can rotate in the sleeve 12 without air leakage at the connection between the sleeve 12 and the rotating tube 11.

[0030] A heating device 13 and a fan 14 are fixedly installed on the top surface of the base plate 1, and a pipeline is connected between the fan 14 and the heating device 13. The air outlet of the fan 14 is fixedly connected to the air supply pipe 15, and the end of the air supply pipe 15 extends into the circular groove 5 and is connected to the sleeve 12. When the fan 14 is started, the hot air in the heating device 13 is sucked into the interior of the air supply pipe 15 through the fan 14, and then the air is passed into the interior of the sleeve 12 that is rotatably sleeved on the outer wall of the rotating tube 11 through the air supply pipe 15.

[0031] Two arc blocks 16 are symmetrically fixedly connected to the bottom surface of the hollow disk 6, and an annular groove is provided at the bottom of the circular groove 5. The two arc blocks 16 fixedly connected to the bottom of the hollow disk 6 are respectively slidably connected to the inside of the annular groove opened at the bottom of the circular groove 5. Thanks to the two arc blocks 16 fixedly connected to the lower end of the hollow disk 6 being respectively slidably connected to the inside of the annular groove opened at the bottom of the circular groove 5, the rotation direction of the hollow disk 6 can be effectively limited, and the stability of the hollow disk 6 during rotation can be further improved.

[0032] A one-way valve 17 is fixedly installed inside the air outlet pipe 9. Thanks to the setting of the one-way valve 17, it can effectively prevent the granular or powdered chemical raw materials inside the drying cylinder 3 from entering the hollow disk 6 or the stirring tube 8 through the air outlet pipe 9.

[0033] A sealing ring 18 is fixedly mounted on the outer wall of the hollow disk 6, and the outer wall of the sealing ring 18 slides and fits against the inner wall of the circular groove 5. The sealing ring 18 can form a seal between the outer wall of the hollow disk 6 and the inner wall of the circular groove 5 without affecting the rotation of the hollow disk 6, thereby preventing chemical raw materials from entering the interior of the circular groove 5 through the gap between the hollow disk 6 and the circular groove 5.

[0034] An exhaust hole is provided on the side wall of the drying cylinder 3, and a barrier net is fixedly connected to the exhaust hole. The exhaust hole and the barrier net can discharge the wet air in the drying cylinder 3 while preventing the chemical raw materials from being discharged from the drying cylinder 3.

[0035] How it works

[0036] When the raw material drying device is used, first open the feed pipe on the top surface of the drying cylinder 3 and put the chemical raw materials into the drying cylinder 3, then start the heating device 13, and suck the air into the interior thereof through the heating device 13 and heat it, then start the fan 14, and suck the hot air in the heating device 13 into the interior of the air delivery pipe 15 through the fan 14, and then pass the air into the interior of the sleeve 12 that is rotatably sleeved on the outer wall of the rotating tube 11 through the air delivery pipe 15. At this time, thanks to the air inlet hole opened on the side wall of the rotating tube 11, and the air inlet hole is located at the sleeve of the sleeve 12, the air will enter the rotating tube through the air inlet hole. 11, and then the processed air is passed into the hollow disk 6, the connecting pipe 7 and the stirring tube 8 through the rotating pipe 11, and then ejected into the interior of the chemical raw material through the top surface of the hollow disk 6 and the air outlet pipe 9 fixedly connected to the stirring tube 8. At this time, the motor 10 is started, and the rotating tube 11 fixedly connected to the end of its rotating shaft and the hollow disk 6 and the stirring tube 8 connected to the rotating tube 11 are driven by the motor 10 to rotate, so that the hot air is sprayed to the bottom of the chemical raw material through the hollow disk 6, and at the same time, the hot air is sprayed to the interior of the chemical raw material through the stirring tube 8 and rotated, so as to speed up the drying efficiency of the chemical raw material.
