[0002] In fertilizer production, tower granulation technology is a widely used technique. Molten liquid is transported to the top of the tower, and small droplets are sprayed out by rotating granulation nozzles. As they fall into the air, they condense into granules when they encounter cold air.

The spraying mechanism has a cylindrical orifice nozzle and a rotary drive assembly. The cylindrical orifice nozzle is equipped with a cleaning mechanism, which has an adsorption assembly with a suction port close to the inner wall of the cylindrical orifice nozzle. The cleaning mechanism also includes a suction assembly. Although the above patent solves the problem of removing some foreign matter by setting up a cleaning mechanism, when the internal rotating assembly rotates at high speed, foreign matter rotates at high speed and enters the orifice, causing blockage. In addition, the solution on the outside of the orifice tends to accumulate on the outside and fall to the bottom, resulting in inconsistent granulation size and affecting use.
[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

Detailed Implementation
[0031] The present invention will be further described below with reference to the accompanying drawings:
[0032] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] like Figures 1 to 11 As shown, a high-efficiency granulation device for high-tower production includes a tower top 2 and a barrel-shaped nozzle 4 fixedly connected to the tower top 2. The barrel-shaped nozzle 4 is provided with a spiral column 8, an extraction pipe 6, a rotation control device 7, and a rotation spraying cleaning mechanism 5 from the inside to the outside.
[0034] like Figures 4 to 6 As shown, the rotary spray cleaning mechanism 5 includes a circular plate 509, the diameter of which is the same as the inner diameter of the barrel-shaped nozzle 4. This design prevents liquid from flowing out from above the circular plate 509. Multiple fan blades 501 are fixedly connected to one end of the circular plate 509 near the top 2, using the fan blades 501 to throw the liquid out of the barrel-shaped nozzle 4. Multiple telescopic chambers 505 are fixedly connected to the other end of the circular plate 509. A telescopic cleaning device 506 is slidably connected inside the telescopic chamber 505. Long arc grooves 507 are provided on both sides of the telescopic chamber 505 to facilitate the sliding of the telescopic cleaning device 506. The telescopic cleaning device 506 includes a half-frame 5061 slidably connected to the telescopic chamber 505. A spring 5065 is fixedly connected to the outer side of the half-frame 5061 near the center of the circular plate 509. One end of the spring 5065 is fixedly connected to the telescopic chamber 505. A bearing 5063 is rotatably connected inside the half-frame 5061. A shaft 5062 is rotatably connected in the middle of the 063. The shaft 5062 is slidably connected to the long arc groove 507. The outer surface of the bearing 5063 is provided with four convex shafts 5064. The advantage of this design is that when the rotary spray cleaning mechanism 5 rotates up and down, when the convex shaft 5064 hits the inner wall of the barrel-shaped nozzle 4, the spring 5065 is compressed, and the half frame 5061 drives the bearing 5063 to move inward. If it encounters the spray hole 401, the spring 5065 relaxes, pushing the shaft 5064 into the spray hole 401 and pushing out foreign objects inside the spray hole 401. The circular plate 509 is provided with a sliding hole 503 in the middle. There are four through holes 502 around the sliding hole 503. There are two fixed posts 504 of different heights in the sliding hole 503. An arc block 508 is rotatably connected to the fixed post 504.
[0035] like Figure 9As shown, the extraction tube 6 is hollow inside, and the upper part of the extraction tube 6 is provided with multiple holes 601. A reciprocating screw 602 is provided in the middle of the outer side of the extraction tube 6. The bottom of the extraction tube 6 is provided with multiple connecting posts 603 that are fixedly connected to the bottom of the barrel-shaped nozzle 4. The arc block 508 slides inside the groove of the reciprocating screw 602. The advantage of this is that the arc block 508 slides inside the groove of the reciprocating screw 602, which is conducive to the up-and-down reciprocating rotation of the rotating spray cleaning mechanism 5.
[0036] like Figure 8 As shown, the rotation control device 7 includes a ring gear 701 rotatably connected to the upper end of the extraction tube 6. One end of the ring gear 701 is fixedly connected to four limiting posts 702 that are slidably connected to the through hole 502. One end of each limiting post 702 is provided with a fixing ring 703 rotatably connected to the extraction tube 6. The spiral column 8 rotates inside the extraction tube 6, and one end of the spiral column 8 is rotatably connected to the bottom of the barrel-shaped nozzle 4.
[0037] like Figure 3 As shown, a drive device 1 is fixedly connected to the upper end of the tower top 2. The extended end of the drive device 1 is fixedly connected to the spiral column 8. A gear 12 is fixedly connected to the extended end of the drive device 1. A fixed shaft 10 is rotatably connected to the side of the tower top 2 near the gear 12. A gear 11 is fixedly connected to one end of the fixed shaft 10, and a gear 13 is fixedly connected to the other end of the fixed shaft 10. Gear 11 meshes with gear 12 for transmission, and gear 13 meshes with ring gear 701 for transmission. A collection hood 9 is fixedly connected above the extraction pipe 6. A foreign matter storage chamber 202 is sealed to one end of the collection hood 9. The foreign matter storage chamber 202 is fixedly connected to the bottom of the tower top 2, allowing the foreign matter collected by the spiral column 8 to be discharged into the foreign matter storage chamber 202 at the bottom of the tower top 2. A feeding port 201 is provided on the tower top 2, which is connected to a barrel-shaped nozzle 4 for convenient discharge of liquid into the interior.
[0038] like Figure 10 As shown, the barrel-shaped nozzle 4 has multiple evenly arranged spray holes 401 on its surface. Multiple connecting posts 402 are fixedly connected to the bottom of the barrel-shaped nozzle 4. A groove 403 is fixedly connected to one end of each connecting post 402. The groove 403 is shaped like an inverted "hat," and its diameter is larger than that of the barrel-shaped nozzle 4. The advantage of this design is that during operation, liquid outside the spray holes 401 would flow to the ground, causing inconsistent particle size. Furthermore, foreign objects pushed out of the spray holes 401 by the convex shaft 5064 would also flow to the bottom. However, after installing the groove 403, both liquid and foreign objects remain in the groove 403. The liquid returns to the circular plate 509 via the spiral column 8 and is pushed out of the spray holes 401 by the fan blades 501, while the foreign objects return to the foreign object storage chamber 202. The tower top 2 and the barrel-shaped nozzle 4 are fixedly connected by fixing bolts 3, facilitating installation and subsequent maintenance.
[0039] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.
[0040] Working process: First, start the drive device 1. The drive device 1 rotates, which drives the spiral column 8 to rotate quickly. The gear 12 on the extended end of the drive device 1 rotates, which drives the gear 11 to rotate. The gear 11 drives the fixed shaft 10 to rotate. The fixed shaft 10 drives the gear 13 to rotate. The gear 13 drives the ring gear 701 to rotate. The ring gear 701 drives the rotating spray cleaning mechanism 5 to rotate up and down.
[0041] After the device is started, liquid is injected into the feed port 201. The liquid enters the circular plate 509 in the barrel-shaped nozzle 4 and is sprayed out from the spray hole 401 through the fan blade 501. As the rotary spray cleaning mechanism 5 continuously rotates up and down, the convex shaft 5064 in the telescopic cleaning device 506 at the bottom enters the spray hole 401 when it rotates, pushing the foreign objects blocking the spray hole 401 out of the barrel-shaped nozzle 4 and onto the groove 403. The foreign objects then slide down to the middle of the groove 403. At this time, the central spiral column 8 transports the foreign objects along with the liquid dripping from the barrel-shaped nozzle 4 to the top. When passing through the hole 601, the liquid flows out and remains on the circular plate 509, and is then thrown out by the fan blade 501 (the reason why the foreign objects do not block the hole 601 is because the foreign objects are not subjected to such a large force by the rotation of the fan blade 501). After the foreign objects rise, they finally flow into the foreign object storage chamber 202 through the collection cover 9. The staff only needs to remove the foreign objects from the foreign object storage chamber 202 periodically.
[0042] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
