Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production, and more specifically, to an accurate control and addition device for additives in the preparation of compound fertilizers in high towers. Background Art

[0002] The preparation of compound fertilizers in high towers is to mix basic fertilizers such as urea, ammonium phosphate, and potassium fertilizers in a high-temperature molten state and make granular compound fertilizers through the high-tower granulation process. During the process of preparing compound fertilizers in high towers, the accurate addition of additives plays a crucial role in the quality of compound fertilizers.

[0003] After retrieval, the Chinese patent with the publication number CN220004213U discloses an additive feeding and adding device. For a general feed mixing device, it cannot crush the caked additives, resulting in the feed not being fully integrated with the additives. If animals accidentally ingest the caked additives, it will affect the health of the animals. With the setting of the over-crushing mechanism, when the grinding roller makes a circular motion inside the grinding cylinder, the grinding roller rotates on its own. The grinding roller cooperates with the grinding cylinder to roll and crush the caked additives. The crushed additives will fall into the separation cylinder through the filter holes of the grinding cylinder. The uncrushed additives cannot pass through the filter holes of the grinding cylinder, and the grinding roller will continue to roll and crush them until the additives are crushed and filtered out from the grinding cylinder, so as to realize the crushing of caked additives, avoid the situation that a general feed mixing device cannot crush caked additives, resulting in the feed not being fully integrated with the additives, and animals accidentally ingesting caked additives will affect the health of the animals.

[0004] During the production process of compound fertilizers, after the additive addition process is completed, there is often a certain amount of additive residue in the pre-addition tank, which will cause a deviation between the actual addition amount of the additive to the compound fertilizer and the preset value, affecting the proportion accuracy of the additive in the compound fertilizer.

[0027] The blowing mechanism includes a support cross plate 11 which is fixed at the top of the support plate 4. One end of the support cross plate 11 is fixedly connected with a top plate 12. At the top of the top plate 12, a blower 13 is fixedly installed. The bottom of the blower 13 is fixedly connected with a telescopic hose 15. The bottom of the telescopic hose 15 is fixedly connected with a lifting exhaust pipe 16. An electric push rod 17 is fixedly installed at the bottom of the top plate 12. The bottom of the electric push rod 17 is fixedly connected with a lifting plate 18.

[0028] As shown in Figure 1 、 2 、3, and 5, the moving rod 8 is slidably connected with the fixed sleeve 6. One end of the connecting plate 9 is fixedly connected with the pre-addition tank 1, which is convenient for the connecting plate 9 and the pre-addition tank 1 to shake up and down.

[0029] As shown in Figure 1 、 2 、3, and 5, the bottom of the support plate 4 is fixedly connected with a bottom plate 19. The lifting plate 18 is fixedly connected with the lifting exhaust pipe 16, which improves the stability of the device.

[0030] As shown in Figure 3 、 5 、 as shown in 24, a through hole 14 is formed on the bottom surface of the top plate 12. The telescopic hose 15 is arranged inside the through hole 14, which is convenient for the telescopic hose 15 to expand and contract inside the through hole 14 and is convenient for use.

[0031] As shown in Figure 5 、 as shown in 29, the scraping mechanism includes a rotating shaft 22 which is installed inside the pre-addition tank 1. At the top of the rotating shaft 22, a motor 20 is fixedly installed. The motor 20 is fixedly installed at the top of the pre-addition tank 1. The rotating shaft 22 is rotatably connected with the pre-addition tank 1. The top of the rotating shaft 22 penetrates through the pre-addition tank 1 and extends to the top of the pre-addition tank 1. One side of the rotating shaft 22 is fixedly connected with a connecting rod 21. One end of the connecting rod 21 is fixedly connected with a rotating scraper 23. A valve 24 is fixedly installed at the bottom of the discharge pipe 2, which is convenient for scraping the residual additive and further avoids the residue of the additive.

[0032] Working principle of the utility model: During the use of the precise control additive feeding device for tower-prepared compound fertilizer provided by the utility model, the pre-feeding tank 1 temporarily stores the compound fertilizer additive to be added, and the additive is transported into the technological process of tower-prepared compound fertilizer through the discharge pipe 2. After the additive feeding is completed, the vibration motor 10 is started, and the vibration generated by it is transmitted to the additive inside through the pre-feeding tank 1. The vibration causes the pre-feeding tank 1 to shake, thereby driving the connecting plate 9 to move. The connecting plate 9 is connected to the fixed sleeve 6 through the moving rod 8, and the moving rod 8 can slide inside the fixed sleeve 6. The spring 7 continuously expands and contracts during the vibration, absorbing and releasing energy to ensure the smoothness of the vibration. Through the vibration, the residual additive inside the pre-feeding tank 1 is affected by the vibration and falls from the discharge pipe 2, reducing the residual amount of the additive in the tank. When it is necessary to further avoid additive residue, the blower 13 is started. The blower 13 is fixed on the top of the top plate 12, and air is transported to the lifting exhaust pipe 16 through the telescopic hose 15. The electric push rod 17 is started to drive the lifting plate 18 to move up and down. The lifting plate 18 is fixedly connected to the lifting exhaust pipe 16, so that the lifting exhaust pipe 16 can move up and down. Under the action of the electric push rod 17, the lifting exhaust pipe 16 moves above the feeding pipe 3. At this time, the air blown out by the blower 13 enters the inside of the pre-feeding tank 1 through the lifting exhaust pipe 16, and the blowing of the air further promotes the residual additive inside the pre-feeding tank 1 to fall, reducing the residue and improving the feeding accuracy of the additive;

[0033] In order to further remove the additive residues on the inner wall of the pre-feeding tank 1, the motor 20 is started. The motor 20 is fixed on the top of the pre-feeding tank 1, and its output shaft is connected to the rotating shaft 22. The motor 20 drives the rotating shaft 22 to rotate. The rotating shaft 22 is rotatably connected to the pre-feeding tank 1 and penetrates through the top of the pre-feeding tank 1 and extends to the top. On one side of the rotating shaft 22, a connecting rod 21 is fixedly connected. One end of the connecting rod 21 is fixedly connected with a rotating scraper 23. When the rotating shaft 22 rotates, the connecting rod 21 and the rotating scraper 23 also rotate accordingly. During the rotation of the rotating scraper 23, it contacts the inner wall of the pre-feeding tank 1 and scrapes off the residual additive on the inner wall. The scraped-off additive falls from the discharge pipe 2 under the action of gravity, further reducing the residual amount of the additive and improving the feeding accuracy.

[0034] Finally: The above embodiments are only illustrative of the principles and effects of the utility model, and are not used to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model.
