[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: See Figure 1-4 , a chemical raw material screening and drying device, including a base 10, a shell 11 is provided at the top of the base 10, and two vertical rods 6 are fixed on the outer wall of the shell 11, and the bottom ends of the vertical rods 6 are welded to the top of the base 10, a fixed disk 13 is fixed to the inner wall of the shell 11, and a protective shell 8 is installed at the bottom end of the fixed disk 13, a servo motor 9 is installed inside the protective shell 8, and the output end of the servo motor 9 extends to the inside of the fixed disk 13 and is installed with a rotating plate 5, the outer wall of the rotating plate 5 is fitted with the inner wall of the fixed disk 13, and the rotating plate 5 and the fixed disk 13 are vertically penetrated with a plurality of leakage holes 12, a driving motor 20 is installed at the top of the shell 11, and a main shaft 19 is installed at the output end of the driving motor 20, the bottom end of the main shaft 19 is connected to the top of the fixed disk 13 through a rotating shaft, and a plurality of push plates 14 are installed at the top of the outer wall of the main shaft 19, and the bottom end of the push plate 14 is on the same horizontal plane as the top of the fixed disk 13;

[0021] A collecting hopper 7 is provided below the housing 11, and the collecting hopper 7 is connected to the base 10 by sliding connection;

[0022] Specifically, Figure 1 and Figure 3As shown, when the device is used, after the material enters the shell 11 of the device, the leakage holes 12 on the rotating plate 5 and the fixed disk 13 are completely misaligned, and the two block each other to ensure that the material is above the fixed disk 13. At this time, the drying operation is performed, and the driving motor 20 drives the main shaft 19 to rotate, and stirs the material through some parts. When the drying is completed, the servo motor 9 is started to drive the rotating plate 5 to rotate a certain angle, so that the leakage holes 12 on the rotating plate 5 and the fixed disk 13 are misaligned, thereby adjusting the size of the longitudinal gap to make it suitable for different screening needs. At this time, as the main shaft 19 rotates, the push plate 14 will sweep the material to the leakage hole 12, so that it can smoothly leak and move to the inside of the collecting bucket 7. After the screening is completed, the collecting bucket 7 can be taken out to process the material. Subsequently, all the leakage holes 12 can be completely aligned to present the largest gap, so that unqualified materials can also pass smoothly to avoid being trapped in the device.

[0023] A gear ring 16 is installed on the top of the inner wall of the housing 11, and a fixed cylinder 15 is fixed to the bottom end of the gear ring 16. A rotating disk 21 is installed on the top of the outer wall of the main shaft 19, and a plurality of stirring shafts 4 are installed on the inner wall of the rotating disk 21 through bearings.

The bottom ends of the stirring shafts 4 are connected to the top of the push plate 14 through a rotating shaft, and a plurality of stirring rods 3 are installed on the outer wall of the stirring shaft 4 below the rotating disk 21.

[0024] An annular guide groove is formed on the inner wall of the fixed cylinder 15, an annular guide block is installed on the outer wall of the rotating disk 21, and the rotating disk 21 is rotatably connected to the fixed cylinder 15 through the cooperation between the annular guide block and the annular guide groove;

[0025] The gear 18 is meshed with the gear ring 16;

[0026] Specifically, Figure 1 and Figure 2 As shown, when the driving motor 20 starts to drive the main shaft 19 to rotate, the rotating disk 21 rotates inside the fixed cylinder 15. At this time, the rotating disk 21 can drive the stirring shaft 4 to follow the rotating disk 21 to rotate around the main shaft 19. At the same time, due to the cooperation of the gear 18 and the gear ring 16, the stirring shaft 4 will also rotate around its own longitudinal axis. In this way, multiple groups of stirring rods 3 will perform stirring operations at different positions inside the outer shell 11, so that the chemical raw materials are fully dispersed, so that each chemical raw material can be fully in contact with the hot air, thereby improving the drying efficiency.

[0028] The shape of the installation pipe 1 is L-shaped, and the installation pipe 1 is connected to the feed pipe 2 through threaded matching, and a protective net is installed on the inner wall of the installation pipe 1;

[0029] Specifically, Figure 1 and Figure 4 As shown, when adding raw materials, the installation tube 1 can be removed and the raw materials can be added from the top of the feed tube 2. After the raw materials are added, the installation tube 1 can be installed to prevent external debris from entering from here. During the drying process, the heater 22 inside the warm air tube 17 drives the air flow, so that the external air passes through the warm air tube 17 and is heated and then sent to the inside of the outer shell 11 to dry the material. These air flows will subsequently leave the device through the feed tube 2 and the installation tube 1 to complete the air flow.
