Description

Technical Field

[0001] This invention relates to the field of fertilizer processing technology, specifically to a fertilizer granulation device. Background Technology

[0002] Compound fertilizers are chemical fertilizers containing two or more nutrients. They have advantages such as high nutrient content, few by-products, and good physical properties. They play a very important role in balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. Common granulation processes for compound fertilizers include: rotary drum granulation, disc granulation, spray granulation, and high tower granulation. In the production of compound fertilizers, the raw materials need to be made into granules for convenient subsequent use.

[0003] Granulators are indispensable in the production of compound fertilizers, but current granulation equipment still has some shortcomings in practical use. For example, the granulation mechanism of traditional granulation equipment often has a fixed structure, making it difficult to flexibly adjust to the needs of different fertilizer particle sizes. When different specifications of fertilizer particles need to be produced, it is usually necessary to replace the entire granulation roller or complex adjustment parts, which is cumbersome and time-consuming, affecting production efficiency. At the same time, some granulation equipment lacks an effective leveling and pretreatment process before the raw materials enter the granulation mechanism, resulting in uneven distribution of raw materials on the granulation roller, which easily leads to problems such as inconsistent particle size and density, thus affecting the quality stability of fertilizer products. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fertilizer granulation device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fertilizer granulation device includes a processing box, with a leveling mechanism fixedly connected to the top of the processing box. A granulation mechanism for granulation is provided inside the processing box, and a driving mechanism for driving the granulation mechanism is provided on the processing box. The granulation mechanism includes two sets of separating rollers rotatably connected inside the processing box. Granulation grooves for granulation are formed on the separating rollers. A limiting plate is slidably connected inside the granulation grooves. A reinforcing column is fixedly connected to one side of the limiting plate. A placement groove is formed on one side of the separating rollers, and a limiting mechanism for limiting the position of the limiting plate is provided inside the placement groove.

[0006] Preferably, the limiting mechanism includes a reinforcing rod fixedly connected inside the placement groove. A sleeve is slidably connected to the outer surface of the reinforcing rod. A connecting rod that cooperates with the reinforcing column is hinged to the outer surface of the sleeve. The other end of the connecting rod is hinged to the reinforcing column. A through hole adapted to the sleeve is opened on one side of the processing box. One end of the sleeve and the reinforcing rod both extend out of the through hole. Multiple sets of positioning holes are opened on the outer surface of the reinforcing rod located outside the processing box. A limiting hole corresponding to the positioning hole is opened on the outer surface of the sleeve. A positioning threaded column is placed inside the limiting hole. Two sets of fixing nuts are threadedly connected to the outer surface of the positioning threaded column.

[0007] Preferably, roller shafts are fixedly connected to both sides of the separating roller. One set of roller shafts is fixedly connected to a rotating rod on one side, and the other set of roller shafts has through holes that are connected to a placement groove and a through hole, respectively. A ball bearing is fixedly connected to the outer surface of the roller shaft. The inner ring of the ball bearing is fixedly connected to the roller shaft, and a mounting base is fixedly connected to the outer ring of the ball bearing. The mounting base is installed on the inner wall of the processing box.

[0008] Preferably, the leveling mechanism includes a mounting frame fixedly connected to the processing box, a feeding hopper fixedly installed inside the mounting frame, through slots on both sides of the feeding hopper, a baffle slidably connected inside the through slots, a placement frame fixedly connected to one side of the feeding hopper, a first electric push rod fixedly installed on the placement frame, the drive end of the first electric push rod fixedly connected to the baffle, a top plate fixedly connected to the top of the feeding hopper, a second electric push rod fixedly installed on the top of the top plate, the drive end of the second electric push rod penetrating the top plate and fixedly connected to a pressure block adapted to the lower half of the inside of the feeding hopper, and a feeding port opened on one side of the processing box.

[0009] Preferably, the drive mechanism includes two meshing gears and a drive motor. One side of the rotating rod extends out of the processing box and is fixedly connected to the gears. One side of the processing box is fixedly connected to a mounting bracket. The drive motor is fixedly mounted on the mounting bracket. The drive end of the drive motor is fixedly connected to one of the gears via a coupling.

[0010] The beneficial effects of this invention are as follows: The fertilizer granulation device provided by this invention allows the limiting plate inside the granulation tank to slide along the tank body under the action of the reinforcing column and connecting rod. The operator only needs to push the sleeve outside the processing box to make the sleeve slide along the reinforcing rod, which in turn pulls or pushes the reinforcing column via the connecting rod, thereby changing the position of the limiting plate inside the granulation tank. Once the limiting plate is in position, the positioning threaded column is passed through the limiting hole on the sleeve and screwed into the corresponding positioning hole on the reinforcing rod. Then, it is locked by two sets of fixing nuts, thus achieving a stable limiting of the limiting plate and changing the effective volume of the granulation tank to meet different specifications. The production requirements for fertilizer granules have been met, eliminating the tedious operation of replacing the entire granulation roller and significantly improving production efficiency. At the same time, the flattening mechanism solves the problem of uneven raw material distribution. During feeding, the first electric push rod drives the baffle to slide in the through groove, which can flexibly control the feeding speed of the feed hopper; the second electric push rod drives the pressing block to move up and down in the lower half of the feed hopper, which can initially compact and flatten the raw material, so that after the raw material enters the processing box through the feed port, it can be evenly distributed on the two sets of separating rollers, ensuring that the granules are uniform in size and density during the granulation process, effectively improving the quality stability of fertilizer products.

Therefore, they should not be construed as limitations on this invention.

[0014] Example 1, as Figure 1 - Figure 9 As shown, the present invention provides a fertilizer granulation device, including a processing box 1. A leveling mechanism 2 is fixedly connected to the top of the processing box 1. A granulation mechanism 3 for granulation is provided inside the processing box 1. A driving mechanism 4 for driving the granulation mechanism 3 is provided on the processing box 1. The granulation mechanism 3 includes two sets of separating rollers 31 rotatably connected inside the processing box 1. A granulation groove 32 for granulation is opened on the separating rollers 31. A limiting plate 33 is slidably connected inside the granulation groove 32. A reinforcing column 34 is fixedly connected to one side of the limiting plate 33. A placement groove 35 is opened on one side of the separating rollers 31. A limiting mechanism for limiting the limiting plate 33 is provided inside the placement groove 35. In actual use, the limiting plate 33 can be slid in the granulation groove 32 by activating the limiting mechanism, thereby changing the distance between the limiting plate 33 and the bottom of the granulation groove 32, that is, adjusting the effective volume of the granulation groove 32.

[0015] Example 2, as Figure 1 - Figure 9As shown, the limiting mechanism includes a reinforcing rod 36 fixedly connected inside the placement groove 35. A sleeve 37 is slidably connected to the outer surface of the reinforcing rod 36. A connecting rod 38 that cooperates with the reinforcing column 34 is hinged to the outer surface of the sleeve 37. The other end of the connecting rod 38 is hinged to the reinforcing column 34. A through hole 5 adapted to the sleeve 37 is opened on one side of the processing box 1. One end of both the sleeve 37 and the reinforcing rod 36 extends out of the through hole 5. Multiple sets of positioning holes 39 are opened on the outer surface of the reinforcing rod 36 located outside the processing box 1. A limiting hole 310 corresponding to the positioning hole 39 is opened on the outer surface of the sleeve 37. A positioning threaded post 311 is placed inside the limiting hole 310. Two sets of fixing nuts are threadedly connected to the outer surface of the positioning threaded post 311. The two sets of fixing nuts on the positioning threaded post 311 are unscrewed, and the positioning threaded post 311 is moved out of the limiting hole 310. Remove the sleeve 37 from the positioning hole 39 and push or pull the sleeve 37 located outside the processing box 1, so that the sleeve 37 slides along the outer surface of the reinforcing rod 36. When the sleeve 37 slides, it drives the connecting rod 38 hinged to it to move. The connecting rod 38 then pulls or pushes the reinforcing column 34, so that the reinforcing column 34 drives the limiting plate 33 to slide in the granulation tank 32, thereby changing the position of the limiting plate 33 in the granulation tank 32. When the limiting plate 33 is adjusted to a suitable position, after the granulation tank 32 forms a cavity of the required volume, pass the positioning threaded column 311 through the limiting hole 310 on the sleeve 37 and screw it into the corresponding positioning hole 39 on the reinforcing rod 36. Then screw two sets of fixing nuts on the outer surface of the positioning threaded column 311. The sleeve 37 and the reinforcing rod 36 are fastened together by the fixing nuts, thus completing the limiting and fixing of the limiting plate 33.

[0016] Both sides of the separating roller 31 are fixedly connected to roller shafts 312. One set of roller shafts 312 is fixedly connected to a rotating rod 313 on one side, and the other set of roller shafts 312 has through holes 316. The through holes 316 are connected to the placement groove 35 and the through hole 5 respectively. The outer surface of the roller shaft 312 is fixedly connected to a ball bearing 314. The inner ring of the ball bearing 314 is fixedly connected to the roller shaft 312, and the outer ring of the ball bearing 314 is fixedly connected to a mounting seat 315. The mounting seat 315 is installed on the inner wall of the processing box 1. By setting the through holes 316, the components of the limiting mechanism, such as the reinforcing column 34, connecting rod 38, sleeve 37 and reinforcing rod 36, can pass through the roller shaft 312 and connect to the external operating structure. This ensures that during the rotation of the separating roller 31, the adjustment part of the limiting mechanism can cooperate with the external through hole 5 through the through holes 316 to achieve stable control of the position of the limiting plate 33.

[0017] Example 3, as Figure 1 - Figure 9As shown, the leveling mechanism 2 includes a mounting frame 43 fixedly connected to the processing box 1. A feeding hopper 22 is fixedly installed inside the mounting frame 43. Both sides of the feeding hopper 22 have through slots 23, and baffles 24 are slidably connected inside the through slots 23. A placement frame 25 is fixedly connected to one side of the feeding hopper 22. A first electric push rod 26 is fixedly installed on the placement frame 25. The driving end of the first electric push rod 26 is fixedly connected to the baffle 24. A top plate 27 is fixedly connected to the top of the feeding hopper 22. A second electric push rod 28 is fixedly installed on the top of the top plate 27. The drive end of the push rod 28 passes through the top plate 27 and is fixedly connected to a pressing block 29 that is adapted to the lower half of the inside of the feed hopper 22. A feed inlet 210 is opened on one side of the processing box 1. The fertilizer raw material is poured into the feed hopper 22, and the second electric push rod 28 is started. The drive end of the second electric push rod 28 drives the pressing block 29 to move up and down in the lower half of the feed hopper 22 to initially compact and flatten the falling raw material, ensuring that the raw material can be evenly spread on the surface of the two sets of separating rollers 31. Then the first electric push rod 26 is started to pull the baffle 24, so that the raw material falls into the inside of the processing box 1.

[0018] The drive mechanism 4 includes two meshing gears 41 and a drive motor 42. One side of the rotating rod 313 extends out of the processing box 1 and is fixedly connected to the gears 41. A mounting bracket 43 is fixedly connected to one side of the processing box 1. The drive motor 42 is fixedly mounted on the mounting bracket 43. The drive end of the drive motor 42 is fixedly connected to one of the gears 41 through a coupling. The drive motor 42 drives the gear 41 connected to it to rotate through the coupling. Since the two gears 41 mesh with each other, the other gear 41 rotates in the opposite direction. The rotation of the gears 41 drives the rotating rod 313 to rotate, and the rotating rod 313 in turn drives the roller shaft 312 and the separating roller 31 connected to it to rotate.

[0019] Working principle: In use, first, according to the required fertilizer granule specifications, adjust the effective volume of the granulation tank 32 through the limiting mechanism. Specifically, unscrew the two sets of fixing nuts on the positioning threaded post 311, remove the positioning threaded post 311 from the limiting hole 310 and the positioning hole 39, then push or pull the sleeve 37 located outside the processing box 1, causing the sleeve 37 to slide along the outer surface of the reinforcing rod 36. When the sleeve 37 slides, it drives the connecting rod 38 hinged to it to move. The connecting rod 38 then pulls or pushes the reinforcing post 34, causing... The reinforcing column 34 drives the limiting plate 33 to slide within the granulation tank 32, thereby changing the position of the limiting plate 33 within the granulation tank 32. When the limiting plate 33 is adjusted to the appropriate position, and the granulation tank 32 forms a cavity of the required volume, the positioning threaded column 311 is passed through the limiting hole 310 on the sleeve 37 and screwed into the corresponding positioning hole 39 on the reinforcing rod 36. Then, two sets of fixing nuts are screwed onto the outer surface of the positioning threaded column 311, and the sleeve 37 and the reinforcing rod 36 are fastened together by the fixing nuts, thus completing the connection of the limiting plate 34. After the limit switch 3 is fixed, the fertilizer raw material is poured into the feed hopper 22. The second electric push rod 28 is activated, and the drive end of the second electric push rod 28 drives the pressure block 29 to move up and down in the lower half of the feed hopper 22 to initially compact and level the falling raw material, ensuring that the raw material can be evenly spread on the surface of the two sets of separating rollers 31. Then, the first electric push rod 26 is activated to pull the baffle 24, so that the raw material falls into the processing box 1. Next, the drive mechanism 4 is activated, and the drive motor 42 drives a set of gears 4 connected to it through the coupling. 1. As the two sets of gears 41 mesh with each other, the other set of gears 41 rotates in the opposite direction. The rotation of gear 41 drives the rotating rod 313 to rotate, which in turn drives the roller shaft 312 and the separating roller 31 connected to it to rotate. When the raw material falls on the rotating separating roller 31, the raw material is carried into the granulation trough 32 between the two sets of separating rollers 31. As the separating roller 31 continues to rotate, the raw material in the granulation trough 32 is squeezed to form granules. The formed granules fall from between the separating rollers 31, completing the granulation process.
