[0002] Compound fertilizer drying equipment is a key piece of equipment in compound fertilizer production. It is mainly used to remove internal moisture from granules, improve granule strength and shelf life. The mainstream equipment is the rotary drum dryer, which consists of a slightly inclined and rotatable cylinder. Wet material enters from the top of one end and comes into contact with hot air, such as hot air or flue gas, flowing through the cylinder in a co-current or counter-current manner. The forward-moving baffles on the inner wall of the cylinder continuously lift and sprinkle the material, enhancing the heat contact surface, increasing the drying rate, and promoting the forward movement of the material. The dried product is collected from the bottom of the other end. This equipment has many advantages: large processing capacity, low fuel consumption, low drying cost, high temperature resistance, and can withstand the rapid drying of materials by high-temperature hot air. It has strong scalability, is designed with production margin in mind, and does not require equipment replacement when production increases. The equipment adopts a self-aligning towing wheel structure to reduce wear and power consumption, has strong overload resistance, stable operation, and high reliability.

[0003] However, existing compound fertilizer drying devices generally do not have dust removal functions. Furthermore, if external dusty air enters the drying device directly without filtration, it may carry pollutants such as heavy metals and microorganisms. After mixing with the compound fertilizer, it may reduce the purity of the product and even cause agricultural non-point source pollution. Therefore, we need a compound fertilizer drying device with dust removal functions. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides a compound fertilizer drying device with dust removal function, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the equipment includes a drying chamber 1, a support 2 fixedly connected to the bottom of the drying chamber 1, a conveyor belt 3 inside the drying chamber 1, a material feeding assembly 4 inside the drying chamber 1, and a dust removal assembly 5 on one side of the drying chamber 1. The material feeding assembly 4 includes a fixed rack 401, which is fixedly connected to the inner wall of the drying chamber 1. A rotating gear 402 is meshed with the outer wall of the fixed rack 401. A material feeding column 403 is fixedly connected to the inner wall of the rotating gear 402. A movable frame 404 is rotatably connected to the outer wall of the material feeding column 403. A fixed rod 405 is fixedly connected to the top of the movable frame 404. A first sleeve 406 is fixedly connected to the top of the fixed rod 405. A first screw 407 is threadedly connected to the inner wall of the first sleeve 406. A fixed block 408 is fixedly connected to one side of the drying chamber 1. A first motor 409 is installed at one end of the first screw 407 to pour raw materials onto the conveyor belt. 3. Start the conveyor belt 3 to transport fertilizer, then start the fan 511 and the heating wire 512 to draw air in through the opening of the protective plate 513. After the air passes through the filter cartridge 509 to remove dust, it enters the air cylinder 510 to complete the dust removal and transportation of the air. Then, the air is heated by the heating wire and blown onto the raw material to complete the dust removal and drying of the raw material. At this time, start the first motor 409 to drive the first screw 407 to rotate, so that the first screw 407 rotates inside the first sleeve 406, causing the first sleeve 406 to move on the outer wall of the first screw 407. In turn, the first sleeve 406 drives the fixed rod 405 to move, and the fixed rod 405 drives the moving frame 404 to move together. The moving frame 404 drives the rotating gear 402 to rotate on the fixed rack 401. The rotating gear 402 drives the material feeding column 403 to rotate, completing the uniform spreading of the raw material and improving the drying effect of the raw material.

[0023] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixed rack 401 forms a rotating structure with the rotating gear 402 and the feeding column 403. The outer wall of the rotating gear 402 meshes with the outer wall of the fixed rack 401, and the inner wall of the rotating gear 402 is fixedly connected to one end of the feeding column 403. By rotating the rotating gear 402 on the outer wall of the fixed rack 401, the feeding column 403 can rotate to flatten the raw material, thereby improving the drying effect of the raw material.

[0024] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the first sleeve 406 forms a movable structure with the movable frame 404 through the fixed rod 405, and the top of the fixed rod 405 is fixedly connected to the bottom of the first sleeve 406, and the bottom of the fixed rod 405 is fixedly connected to the top of the movable frame 404. Through the fixed rod 405, the fixed rod 405 can drive the movable frame 404 to move by moving the first sleeve 406.

[0025] This utility model embodiment provides a compound fertilizer drying device with dust removal function, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the dust removal assembly 5 includes a protective shell 501, which is fixedly connected to one side of the drying chamber 1. A second motor 502 is provided on one side of the protective shell 501. The output end of the second motor 502 is connected to a second screw 503 via a coupling. A second sleeve 504 is threadedly connected to the outer wall of the second screw 503. A movable rack 505 is fixedly connected to the top of the second sleeve 504. A linkage gear 506 is meshed with the outer wall of the movable rack 505. A frame 507 is fixedly connected to the top of the linkage gear 506. A brush 508 is fixedly connected inside the frame 507. A filter cartridge 509 is provided inside the protective shell 501. An air cylinder 510 is fixedly connected to the top of the filter cartridge 509. One end of the filter cartridge 509 is fixedly connected to a fan 511, and a heating wire 512 is fixedly connected inside the fan 511. A protective plate 513 is fixedly connected to one side of the protective shell 501. If dust accumulates on the filter cartridge 509, the second motor 502 can be started to drive the second screw 503 to rotate, so that the second screw 503 rotates inside the second sleeve 504, which can cause the second sleeve 504 to move on the outer wall of the second screw 503. This causes the second sleeve 504 to drive the moving rack 505 to move, which in turn causes the moving rack 505 to drive the linkage gear 506 to rotate. The linkage gear 506 drives the frame 507 to rotate, and the brush 508 set on the frame 507 cleans the filter cartridge 509, thus completing the cleaning of the filter cartridge 509.

[0026] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the second screw 503 forms a movable structure with the movable rack 505 via the second sleeve 504. The size of the internal thread of the second sleeve 504 matches the size of the external thread of the second screw 503, and the inner wall of the internal thread of the second sleeve 504 fits against the outer wall of the external thread of the second screw 503. By rotating the second screw 503 inside the second sleeve 504, the second sleeve 504 can move on the outer wall of the second screw 503, thereby driving the movable rack 505 to move, so that the second screw 503 has mobility relative to the movable rack 505.

[0027] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the movable rack 505 forms a rotating structure with the frame 507 through the linkage gear 506, and the outer wall of the linkage gear 506 meshes with the outer wall of the movable rack 505. One side of the linkage gear 506 is fixedly connected to the bottom of the frame 507. Through the meshing connection between the linkage gear 506 and the movable rack 505, the linkage gear 506 can rotate the frame 507, so that the brush 508 on the frame 507 can clean the filter cartridge 509, thereby improving the cleaning effect of the brush 508 on the filter cartridge 509.

[0028] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a brush 508 is fixedly connected to the inner wall of the frame 507, and the brushes 508 are symmetrically arranged on both sides of the frame 507. With the brushes 508 on both sides, the frame 507 can be cleaned on both sides at the same time when it rotates, which improves the cleaning effect of the brushes 508 on the filter cartridge 509.

[0029] Working principle: Raw materials are poured onto conveyor belt 3, which is then started to transport fertilizer. Fan 511 and heating wire 512 are activated to draw air in through the opening in protective plate 513. After passing through filter cartridge 509 to remove dust, the air enters air cylinder 510 for dust removal and transport. The air is then heated by the heating wire and blown onto the raw materials to complete dust removal and drying. Simultaneously, the first motor 409 is started, driving the first screw 407 to rotate. This causes the first screw 407 to rotate inside the first sleeve 406, moving the first sleeve 406 against the outer wall of the first screw 407. This, in turn, causes the first sleeve 406 to move the fixed rod 405, which in turn moves the moving frame 404. The moving frame 404 then drives the rotating... The rotating gear 402 rotates on the fixed rack 401, which drives the feeding column 403 to rotate, thus achieving uniform spreading of the raw materials and improving the drying effect. If dust accumulates on the filter cartridge 509, the second motor 502 can be started to drive the second screw 503 to rotate, causing the second screw 503 to rotate inside the second sleeve 504. This allows the second sleeve 504 to move on the outer wall of the second screw 503, which in turn drives the moving rack 505 to move. The moving rack 505 then drives the linkage gear 506 to rotate, which in turn drives the frame 507 to rotate. The brush 508 on the frame 507 cleans the filter cartridge 509, thus completing the cleaning of the filter cartridge 509.
