Description
Technical Field

[0002] The fertilizer high-tower pulping and granulation device is a device used to produce fertilizer granules. It usually consists of a high-tower body, a pulping system, a granulation system, a cooling system, a screening system, and a packaging system. This device has the advantages of high production efficiency, uniform particles, high strength, and low agglomeration. It is widely used in the production of nitrogen fertilizers, phosphate fertilizers, potash fertilizers and other fertilizers.
[0003] The granulation components in the existing fertilizer high-tower pulping and granulation device usually spray the slurry into the high tower with a nozzle. During the falling process, the slurry comes into contact with the rising hot air flow, causing the water in the slurry to evaporate rapidly and form granular fertilizer. However, during this process, when the nozzle sprays, the slurry will gradually accumulate at the nozzle due to long-term spraying, causing the nozzle to be blocked. In addition, during the melting and mixing process, some residue will remain on the inner wall, resulting in insufficient melting and mixing of the slurry. Utility Model Content

[0046] In some embodiments, according to Figure 1 As shown, the second melting component is consistent with the first melting component. A water tank 32 is provided on one side of the second melting component. The purpose of the water tank 32 is to supply water to the second melting component to dissolve urea particles. Valves 33 are provided on the surfaces of multiple pipes.
[0047] The working principle of the utility model is as follows: the first pulping and granulating component and the second pulping and granulating component form a complete pulping and granulating component. When granular fertilizer needs to be produced;
[0048] First, the urea solution is prepared through the second melting component. The staff first pours urea granules into its melting chamber 14 through the feed port of the second melting component. Then, the water valve of the water tank 32 is opened, and the water in the water tank 32 flows into the melting chamber 14 through the pipeline. When the water flows fully, the valve 33 is closed, and the steam engine 18 and the second motor 15 are started. At this time, the steam heats the melting chamber 14 through the steam return pipe 19. The second motor 15 drives the first stirring rod 16 to stir the material to make it fully dissolved and mixed. The first stirring rod 16 drives the first inner wall scrapers 17 on both sides to rotate, thereby scraping off the urea granules attached to the inner wall of the melting chamber 14 to make it fully dissolved, thereby obtaining a urea solution.
[0049] Then, the urea mixed liquid is mixed with the potash fertilizer and the phosphate fertilizer through the two mixing chambers 23 of the mixing component to form a slurry;
[0050] First, the staff adds potash fertilizer and phosphate fertilizer into the two mixing chambers 23 respectively, and opens the valve 33 between the mixing component and the second melting component. At this time, the urea solution will flow from the melting chamber 14 in the second melting component through the pipeline into the mixing chamber 23 where the potash fertilizer is located and the mixing chamber 23 where the phosphate fertilizer is located.
[0051] At the same time, the dual-axis motor 25 is turned on. At this time, the output ends on both sides of the dual-axis motor 25 will drive the two second connecting shafts 26 to rotate, thereby driving the two third bevel gears 27 to rotate. The rotation of the third bevel gear 27 drives the fourth bevel gear 28 to rotate. The rotation of the fourth bevel gear 28 drives the second rotating shaft 29 and the second stirring rod 30 at the bottom to rotate. The rotation of the second stirring rod 30 drives the second inner wall scrapers 31 on both sides to rotate. Thus, the dual-axis motor 25 drives the two sets of second stirring rods 30 and second inner wall scrapers 31 to rotate in the two mixing chambers 23 respectively.
[0052] When the urea solution is fully mixed with the potash fertilizer and phosphate fertilizer to form a slurry, the pulping is completed;
[0053] After the slurry is prepared, the slurry is heated again by the first melting component;
[0054] Open the valve 33 between the mixing component and the spiral conveying component. At this time, the slurry will enter the inlet of the spiral conveying component through the pipeline, then enter the spiral conveyor 22, and then enter the outlet of the spiral conveying structure through the spiral conveyor 22 before entering the first melting component. The heating process of the first melting component is consistent with the heating process of the second melting component. After the secondary heating, open the valve 33 on the outlet end pipeline of the second melting component, and the heated slurry will flow into the granulation component through the pipeline for granulation;
[0055] During the granulation process, the slurry is continuously input into the granulation component. At this time, the first motor 5 is turned on. The first motor 5 drives the first connecting shaft 6 and the first bevel gear 7 to rotate, thereby driving the second bevel gear 8, the first rotating shaft 9, the drainage knife 10, the pelletizing knife 12 and the anti-sticking baffle 13 to rotate. The slurry is drained to the surface granulation hole 4 through the drainage groove 11 installed on the drainage knife 10 on the outer shell 3, and then flows to the lower surface through the granulation hole 4 to solidify, and is quickly pelletized by the pelletizing knife 12 to form granular fertilizer, and finally falls to the bottom of the high tower.
