[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 5This utility model provides a fertilizer drying device for selenium-enriched fertilizer production, including a drying chamber 1; a support plate 10 is fixedly connected to the side wall of the drying chamber 1; multiple sets of support legs 11 are fixedly connected to the bottom end of the support plate 10; the support legs 11 are also located at the bottom end of the drying chamber 1; a heating fan 12 is provided at the top end of the support plate 10; an air guide pipe 14 is fixedly connected to the output end of the heating fan 12; the air guide pipe 14 passes through the surface of the drying chamber 1; a chamber door 13 is rotatably connected to the side wall of the drying chamber 1; an air collecting hood 15 is fixedly connected to the end of the air guide pipe 14; brackets 16 are symmetrically fixedly connected to the side wall of the drying chamber 1; a servo motor 17 is fixedly connected to the side wall of the bracket 16; a rotating shaft 18 is fixedly connected to the output end of the servo motor 17; The rotating shaft 18 passes through the surface of the drying chamber 1 and is rotatably connected to it; a turntable 19 is fixedly connected to the end of the rotating shaft 18; multiple sets of placement boxes 110 are provided on the side wall of the turntable 19; a positioning groove 111 is opened at the end of the placement box 110; a first magnetic block 112 is fixedly connected to the side wall of the positioning groove 111; a filter screen 113 is provided on the side wall of the placement box 110; a second magnetic block 114 is fixedly connected to the side wall of the filter screen 113; the second magnetic block 114 and the first magnetic block 112 are connected by magnetic connection; during operation, the drying chamber 1 can be supported by the support legs 11, the support plate 10 can be connected to the drying chamber 1, and the heating fan 12 can be supported by the support plate 10. When it is necessary to dry selenium-rich fertilizer... During the process, staff place selenium-enriched fertilizer into the placement box 110, which is then supported by a turntable 19. After placement, staff insert the second magnetic block 114 into the positioning slot 111, connecting it to the first magnetic block 112, thus installing the filter screen 113. After installation, the servo motor 17 is supported by a bracket 16. The servo motor 17 rotates, driving the rotating shaft 18 to rotate, which in turn rotates the placement box 110. This rotation of the placement box 110 causes the material inside to rotate. Simultaneously, the heating fan 12 operates, and hot air enters through the air duct 14. The air is blown out and then blown into the placement box 110 to dry the selenium-enriched fertilizer. The filter screen 113 has a small mesh size, which reduces the phenomenon of selenium-enriched fertilizer being blown out of the placement box 110. The air collector hood 15 can make the air blown out of the air guide 14 more concentrated. The drying box 1 can be connected to the box door 13. This design is not only simple and convenient to operate, but also allows the selenium-enriched fertilizer to change position continuously during the rotation of the placement box 110. The part in contact with the inner wall of the placement box 110 will be constantly changed. After the hot air enters from the inlet and outlet, it can form a certain airflow circulation inside the box to a certain extent with the rotation of the box, so that the heat can be transferred to all parts of the box, thereby drying the selenium-enriched fertilizer more evenly and improving the processing quality.

[0027] Furthermore, such as Figure 1 - Figure 5 As shown, the turntable 19 has multiple sets of mounting slots 2 on its side wall; a spring rod 21 is fixedly connected to the side wall of the mounting slot 2; a pin 22 is fixedly connected to the end of the spring rod 21; a mounting block 23 is fixedly connected to the side wall of the placement box 110; an insertion hole 24 is provided on the side wall of the mounting block 23; during operation, the operator pulls the pin 22, thereby compressing the spring rod 21, then the operator inserts the mounting block 23 into the mounting slot 2, aligns the pin 22 with the insertion hole 24, and then releases the pin 22, using the spring rod 21 to compress the spring rod 21. The reset function of 1 allows the pin 22 to be inserted into the socket 24, thereby enabling the installation of the placement box 110. By pulling the pin 22, the spring rod 21 is compressed, allowing the pin 22 to be pulled out of the socket 24, thus enabling the disassembly of the placement box 110. This design facilitates the installation and disassembly of the placement box 110, making it easier for workers to remove the dried selenium-enriched fertilizer and clean the placement box 110, thus improving flexibility.

[0028] Furthermore, such as Figure 1 - Figure 5 As shown, multiple sets of fixing rods 3 are fixedly connected to the side wall of the rotating shaft 18; fan blades 31 are fixedly connected to the side wall of the fixing rods 3; during operation, the fixing rods 3 can support the fan blades 31. When the rotating shaft 18 rotates, it can drive the fixing rods 3 to rotate, and the rotation of the fixing rods 3 can drive the fan blades 31 to rotate. The rotation of the fan blades 31 can accelerate the airflow inside the drying chamber 1. This design can accelerate the airflow inside the drying chamber 1, thereby making the selenium-rich fertilizer dry more evenly.

[0029] Furthermore, such as Figure 1 - Figure 5 As shown, a rotating rod 4 is rotatably connected to the inner side of the placement box 110; multiple sets of propeller blades 41 are fixed to the side wall of the rotating rod 4; during operation, the propeller blades 41 can be connected through the rotating rod 4, and the air blown out through the air guide pipe 14 can blow the propeller blades 41 to rotate, thereby turning over the selenium-rich fertilizer in the placement box 110. This design can turn over the selenium-rich fertilizer in the placement box 110, thereby improving the drying effect.

[0030] Furthermore, such as Figure 1 - Figure 5 As shown, a sealing strip 5 is provided on the side wall of the door 13; the sealing strip 5 is connected to the door 13 by adhesive bonding; during operation, the sealing strip 5 can improve the sealing performance, thereby reducing the temperature loss inside the drying oven 1.

[0031] Furthermore, such as Figure 1 - Figure 5 As shown, a rubber pad 6 is provided at the bottom end of the support leg 11; the rubber pad 6 is connected to the support leg 11 by adhesive bonding; during operation, the rubber pad 6 can increase the friction with the ground, and this design can increase the friction with the ground, thereby improving the stability of the equipment during operation.

[0032] Working principle: The drying chamber 1 is supported by the support legs 11. The drying chamber 1 is connected to the support plate 10, which in turn supports the heating fan 12. When the selenium-enriched fertilizer needs to be dried, the operator places the fertilizer into the placement box 110, which is supported by the turntable 19. After placement, the operator inserts the second magnetic block 114 into the positioning slot 111, connecting it to the first magnetic block 112, thus allowing the filter screen 113 to be installed. After installation, the servo motor 17 is supported by the bracket 16. The servo motor 17 drives the rotating shaft 18, which in turn drives the placement box 110, causing it to rotate. This rotation of the placement box 110, in turn, causes the material inside to rotate. Simultaneously, the heating fan 12 operates, blowing hot air through the air duct 14 into the placement box 110 to dry the selenium-enriched fertilizer. The filter screen 113 has a small mesh size, reducing the likelihood of the selenium-enriched fertilizer being blown out of the placement box 110. The air collecting hood 15 further enhances the airflow from the air duct 14. The drying box 1 is connected to the door 13. By pulling the latch 22, the spring rod 21 is compressed. Then, the operator inserts the mounting block 23 into the mounting slot 2, aligns the latch 22 with the insertion hole 24, and releases the latch 22. Using the reset function of the spring rod 21, the latch 22 can be inserted into the insertion hole 24, thus installing the placement box 110. By pulling the latch 22 again, the spring rod 21 is compressed, allowing the operator to pull the latch 22 out of the insertion hole 24, thus disassembling the placement box 110. The fixed rod 3 supports the fan blade 31. When the rotating shaft 18 rotates, it drives the fixed rod 3 to rotate, which in turn drives the fan blade 31 to rotate. The rotation of the fan blade 31 accelerates the airflow inside the drying chamber 1. The rotating rod 4 connects to the propeller blade 41. The air blown out by the air duct 14 drives the propeller blade 41 to rotate, thereby turning the selenium-rich fertilizer in the placement box 110. The sealing strip 5 improves the sealing performance, and the rubber pad 6 increases the friction with the ground.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
