Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and more specifically, it relates to a slurry dispersion structure for a high-tower melting granulator. Background Technology

[0002] In the compound fertilizer production process, tower nozzle granulation technology is currently a more common granulation technology. The molten slurry is sent to the top of the granulation tower and enters the granulation nozzle. Under the rotation of the nozzle, the raw material is sprayed out through the small holes of the nozzle to form droplets. As the droplets fall, they meet the air flowing upwards and gradually cool and crystallize into granules.

[0003] Chinese invention patent application number 202210459370.6 discloses a spiral granulation nozzle and granulator for high-tower compound fertilizer. It sets the spray cup to a spiral blade shape, replacing the traditional orifice structure to prevent the orifice from being blocked. However, large-sized insoluble matter cannot be discharged and will accumulate in the spray cup. The insoluble matter rotates with the spray cup, affecting the balance of the spray cup, which eventually leads to deformation and even adhesion of the sprayed slurry. Cleaning the spray cup requires stopping the machine for disassembly, which affects the processing efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a slurry dispersion structure for a high-tower melt granulator that takes into account both processing efficiency and finished product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A slurry dispersion structure for a high-tower melting granulator includes an mounting plate and a rotating shaft. The mounting plate is an installation structure, and a material cylinder and several stators are connected to the mounting plate. Several discharge holes are opened on the side wall of the material cylinder. The rotating shaft is connected to an external power source, and several rotors are connected to the rotating shaft. Several stators and rotors are arranged alternately, and several discharge ports are opened on both the stators and rotors.

[0007] The present invention is further configured such that: both the stator and the rotor are annular, a plurality of the stators and a plurality of rotors are arranged coaxially, the stator is in contact with the adjacent rotor, the bottom of the rotating shaft is connected to a base plate, and the rotor is fixed on the base plate.

[0008] The present invention is further configured such that: the inner stator has the smallest inner diameter and the outer rotor has the largest inner diameter; the discharge port on the inner stator is the inner material port and the discharge port on the outer rotor is the outer material port; the discharge port diameter between the inner and outer material ports gradually decreases; and the diameter of the outer material port is not greater than the diameter of the discharge port.

[0009] The present invention is further configured such that: an impeller is provided on the rotating shaft, and the impeller can push the slurry toward the stator.

[0010] The present invention is further configured such that: an impeller II is fixed on the base plate, the inner side of the impeller II is fixed on the outer rotor, and the outer side of the impeller II is in contact with the inner wall of the barrel.

[0011] The advantages of this utility model are:

[0012] Several rotors are mounted on the rotating shaft, and several stators are mounted on the mounting plate. The stators and rotors are interleaved and nested together. Several discharge ports are opened on both the stators and rotors. The diameter of the discharge ports gradually decreases from the inside to the outside. When the rotating shaft rotates, the stators and rotors rotate synchronously with each other. Large particles of insoluble matter in the slurry are ground up and mixed into the slurry as they pass through. Finally, they are discharged through the material cylinder. This avoids clogging and prevents the accumulation of large particles. Frequent disassembly and cleaning are not required, which ensures the quality of the finished product and the processing efficiency. Attached Figure Description

[0021] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0022] Please see Figure 1-5 The present invention provides the following technical solution:

[0023] A slurry dispersion structure for a high-tower melting granulator includes a mounting plate 1 and a rotating shaft 4. The mounting plate 1 is a mounting structure, and a material cylinder 2 and several stators 3 are connected to the mounting plate 1. Several discharge holes are opened on the side wall of the material cylinder 2. The rotating shaft 4 is connected to an external power source, and several rotors 6 are connected to the rotating shaft 4. Several stators 3 and rotors 6 are arranged alternately, and several discharge ports 8 are opened on both stators 3 and rotors 6.

[0024] Both the stator 3 and the rotor 6 are annular, and several stators 3 and several rotors 6 are arranged coaxially. The stator 3 is in contact with the adjacent rotor 6. The bottom of the rotating shaft 4 is connected to the base plate 41, and the rotor 6 is fixed on the base plate 41.

[0025] The inner stator 3 has the smallest inner diameter, and the outer rotor 6 has the largest inner diameter. The discharge port 8 on the inner stator 3 is the inner material port, and the discharge port 8 on the outer rotor 6 is the outer material port. The diameter of the discharge port 8 between the inner and outer material ports gradually decreases, and the diameter of the outer material port is not greater than the diameter of the discharge port.

[0026] When large insoluble particles pass through stator 3 and rotor 6 with the slurry, they are ground and dispersed at outlet 8 until they reach the outermost layer. At this point, the particle diameter is smaller than the diameter of the outlet hole, so they can be sprayed out with the slurry, avoiding blockage and material accumulation.

[0027] Impeller 1 5 is installed on the rotating shaft 4. Impeller 1 5 can push the slurry towards the stator 3. Impeller 2 7 is fixed on the base plate 41. The inner side of impeller 2 7 is fixed on the outer rotor 6. The outer side of impeller 2 7 is in contact with the inner wall of the material cylinder 2. Both impeller 1 5 and impeller 2 7 can push the slurry to move outward, promoting the spraying of the slurry.

[0028] Specifically, a number of rotors 6 are arranged on the rotating shaft 4, and a number of stators 3 are arranged on the mounting plate 1. The stators 3 and rotors 6 are interleaved and nested together. A number of discharge ports 8 are opened on both the stators 3 and rotors 6. The diameter of the discharge ports 8 gradually decreases from the inside to the outside. When the rotating shaft 4 rotates, the stators 3 and rotors 6 rotate synchronously with each other. Large particles of insoluble matter in the slurry are ground up and mixed into the slurry as they pass through, and finally discharged through the material cylinder 2. This avoids clogging and prevents the accumulation of large particles. Frequent disassembly and cleaning are not required, which ensures the quality of the finished product and the processing efficiency.
