Description

Technical Field

[0001] This utility model relates to the field of adjustment mechanism technology, specifically to an adjustment mechanism for a compound fertilizer high-tower granulator. Background Technology

[0002] High-tower granulation technology for compound fertilizer is one of the important processes in the production of compound fertilizer. The performance of its core equipment, the high-tower granulator, directly affects the granulation quality, particle size distribution, and production efficiency of the fertilizer. In existing technologies, high-tower granulators typically include a tower top plate, a distribution pipe, and granulation pipes installed on the distribution pipe. Multiple nozzles are located at the lower end of the granulation pipes. Molten slurry is distributed to each granulation pipe through the distribution pipe and then sprayed out through the nozzles. During its descent within the tower, it cools and solidifies into granules.

[0003] However, existing high-tower granulators for compound fertilizer still have some shortcomings in practical use: First, traditional granulation tubes are usually fixed structures, making it difficult to flexibly adjust the spray direction and range of the nozzles according to production needs. This results in limited granulation uniformity and coverage, especially when adjusting the drop point distribution or dealing with different material characteristics, lacking effective adjustment methods. Second, during the granulation process, changes in material flow rate or viscosity can easily cause fluctuations in the internal pressure of the nozzles, affecting the stability of the output and leading to problems such as uneven particle size, tailing, or adhesion. Existing equipment lacks an effective built-in constant pressure regulation mechanism to ensure constant material pressure at the nozzles. In addition, some granulation mechanisms with adjustment functions often use independent drive methods, resulting in complex structures, poor synchronization, and transmission components that are easily affected by dusty environments, leading to low reliability. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustment mechanism for a compound fertilizer high-tower granulator, which solves the problems of unstable angle adjustment of the granulation pipe nozzle and unstable spray pressure leading to uneven granulation diameter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustment mechanism for a compound fertilizer high-tower granulator, comprising a tower top plate, a diversion pipe installed inside the tower top plate via bearings, two symmetrically distributed granulation pipes installed inside the diversion pipe via bearings, multiple evenly distributed nozzles fixedly installed at the lower end of the granulation pipes, a constant pressure adjustment mechanism provided inside the granulation pipes, gears fixedly installed on the outer side of the granulation pipes, a fixing plate fixedly installed on the back of the diversion pipes, two symmetrically distributed racks slidably connected to the front of the fixing plate, a drive shaft fixedly installed on the back of the racks, a rotating shaft installed at the center of the back of the fixing plate via bearings, a lever fixedly installed on the outer side of the rotating shaft, a worm gear fixedly installed on the outer side of the rotating shaft, a dust cover fixedly installed on the back of the fixing plate, a worm gear installed inside the dust cover via bearings, and a motor fixedly installed at the lower end of the dust cover.

[0006] Preferably, a diversion plate is fixedly installed at the center of the bottom inner side of the diversion pipe, and two symmetrically distributed sealing rings are bonded to the bottom inner side of the diversion pipe. The sealing rings are rotatably connected to the granulation pipe, and the sealing rings can seal the connection between the diversion pipe and the granulation pipe.

[0007] Preferably, the rack is slidably connected to the fixed plate, the drive shaft is slidably connected to the waist hole of the fixed plate, and the actuating frame is slidably connected to the drive shaft. The actuating frame can drive the rack to move through the drive shaft.

[0008] Preferably, a guide strip is fixedly connected to the front of the fixing plate, and the guide strip is slidably connected to the rack, so that the guide strip can guide the movement of the rack.

[0009] Preferably, the worm gear meshes with the worm wheel, and the output shaft of the motor is fixedly connected to the worm gear. The motor can provide power to the worm gear, which in turn drives the worm wheel to rotate.

[0010] Preferably, the constant pressure regulating mechanism includes a fixed frame. Multiple evenly distributed fixed frames are fixedly installed on the inner bottom of the granulation tube. A connecting pin is slidably connected inside each fixed frame. A dispersion cover is fixedly installed at the lower end of the connecting pin. A spring is provided on the outer side of the connecting pin. The dispersion cover contacts the nozzle. The raw material liquid can flow along the inclined surface of the dispersion cover and then disperse in a cone shape.

[0011] Preferably, one end of the spring is fixedly connected to the fixing frame, and the other end of the spring is fixedly connected to the connecting pin. The shape of the dispersion cover is trumpet-shaped, and the spring can support the connecting pin through its elastic force.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model effectively improves the precision and stability of the granulation process through integrated and automated design. It adopts a single motor adjustment mechanism, which drives the rack and pinion adjustment mechanism through the worm gear and worm wheel adjustment mechanism and the actuating frame adjustment mechanism. Finally, it precisely controls the gear on the outside of the granulation tube adjustment mechanism, realizing the synchronous reverse swing adjustment of the two granulation tubes. This linkage method not only ensures flexible and precise control of the spraying range and angle, but its worm gear mechanism also has a self-locking capability, which can effectively prevent the equipment from deviating in the vibration environment, thereby significantly improving the uniformity of granulation and the reliability of equipment operation.

[0014] 2. This utility model incorporates a constant pressure regulating mechanism inside the granulation tube. Through the synergistic action of the spring regulating mechanism and the dispersion hood regulating mechanism, the outlet pressure at the nozzle regulating mechanism can be compensated and stabilized in real time. This fundamentally reduces problems such as uneven particle size and tailing caused by pressure fluctuations. At the same time, the overall structure is highly integrated, the sealing ring effectively prevents slurry leakage, and the dust cover provides good protection for the transmission system. This allows the equipment to have a longer service life and lower maintenance requirements in the high-dust and highly corrosive environment of compound fertilizer production.

[0026] Please see Figure 1-8 A diverter plate 18 is fixedly installed at the center of the bottom inner side of the diverter pipe 2.

The drive shaft 11 is slidably connected to the waist hole of the fixed plate 8. The actuating frame 13 is slidably connected to the drive shaft 11. The actuating frame 13 can drive the rack 9 to move through the drive shaft 11. A guide strip 10 is fixedly connected to the front of the fixed plate 8.

[0027] Please see Figure 1-8The constant pressure regulating mechanism 5 includes a fixed frame 51. Multiple evenly distributed fixed frames 51 are fixedly installed on the bottom inner side of the granulation tube 3. A connecting pin 52 is slidably connected inside each fixed frame 51. A dispersion cover 53 is fixedly installed at the lower end of the connecting pin 52. A spring 54 is provided on the outside of the connecting pin 52.

[0028] The specific implementation process of this utility model is as follows:

[0029] I. Synchronous Oscillation Adjustment Principle of Granulation Tube 3: When it is necessary to adjust the spray angle of granulation tube 3, the motor 17 is started. The output shaft of the motor 17 adjustment mechanism drives the worm gear 16 adjustment mechanism to rotate. The worm gear 16 adjustment mechanism meshes with the worm wheel 14 adjustment mechanism fixed on the rotating shaft 12 adjustment mechanism, transmitting the rotational motion of the motor 17 adjustment mechanism to the worm wheel 14, and driving the actuating frame 13 to rotate synchronously through the rotating shaft 12 adjustment mechanism. The actuating frame 13 adjustment mechanism is an eccentric structure, with its two ends embedded in the sliding grooves of the two drive shaft 11 adjustment mechanisms. When the actuating frame 13 adjustment mechanism rotates, it pushes the two drive shaft 11 adjustment mechanisms to make linear movements in opposite directions within the waist hole of the fixed plate 8 adjustment mechanism. The front end of each drive shaft 11 adjustment mechanism is connected to a rack 9. The linear movement of the drive shaft 11 adjustment mechanism drives the two rack 9 adjustment mechanisms to slide synchronously back and forth under the constraint of the guide bar 10 adjustment mechanism. The two rack 9 adjustment mechanisms simultaneously mesh with the gear 7 adjustment mechanisms on the outside of the two granulation tube 3 adjustment mechanisms. The linear motion of the rack 9 adjustment mechanism is ultimately converted into the rotational motion of the gear 7 adjustment mechanism, which in turn drives the two granulation tubes 3 adjustment mechanisms to swing synchronously and in opposite directions around their axes. Due to the adoption of the worm gear 16-worm wheel 14 adjustment mechanism transmission mechanism, its inherent reverse self-locking characteristic can prevent the granulation tubes 3 adjustment mechanism from shifting due to external vibration or material impact when the motor 17 adjustment mechanism stops, thus ensuring the stability of the working angle.

[0030] II. Working Principle of Constant Pressure Adjustment Mechanism 5: During normal operation, the molten slurry enters the granulation pipe 3 and flows towards the nozzle 4. At this time, the material pressure acts on the funnel-shaped inner surface of the dispersing hood 53 adjustment mechanism. When the system pressure increases, the hydraulic pressure overcomes the pre-tightening force of the spring 54 adjustment mechanism, pushing the dispersing hood 53 adjustment mechanism and the connecting pin 52 adjustment mechanism to move upward, compressing the spring 54. This increases the gap between the dispersing hood 53 and the nozzle 4 adjustment mechanism outlet, reduces the flow resistance, and thus releases some pressure, keeping the outlet pressure at the nozzle 4 stable. When the system pressure decreases, the restoring force of the spring 54 adjustment mechanism pushes the connecting pin 52 and the dispersing hood 53 adjustment mechanism downward, reducing the gap with the nozzle 4 and increasing the flow resistance, thereby helping to maintain the pressure at the nozzle 4 from being too low. Through the extension and contraction of the spring 54, the position of the dispersing hood 53 will automatically and instantly fine-tune with the fluctuation of the pipe pressure, forming a dynamic balance, ultimately providing a constant outlet pressure for each nozzle 4 adjustment mechanism, ensuring uniform and stable discharge.
