Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a granulator with a screening function. Background Art

[0002] A granulator with a screening function is a multi-functional device that can complete granulation and screening simultaneously, improving production efficiency and product quality. Its main features include versatility, high efficiency, quality control, and easy operation. The working principle is that the raw materials go through four steps: feeding, granulation, screening, and discharging, ensuring that the particle size of the final product meets the standards. This device is widely used in industries such as pharmaceuticals, chemicals, food, and feed, especially suitable for production environments with strict requirements for particle size and quality.

[0003] After retrieval, a granulator with a screening function with the publication number CN220386478U includes a moving base and a granulator. The top of the moving base is connected to the granulator. The top of the granulator is connected to a feeding port. Inside the feeding port is connected a rolling device. The surface of the granulator is penetrated and connected with a discharging port. Inside the granulator is connected a screening mechanism. Between the moving base and the granulator is connected a transmission mechanism. In the utility model, the vibrating sieve can perform secondary screening on the particles on the surface of the sieve. The screened particles can pass through the sieve and be collected through the discharging port. The remaining particles with unqualified sizes can be collected by using a collection box through the screening port. The rotation of the screw rod can transport the bacterial fertilizer upward. When the bacterial fertilizer is transported to a position close to the discharging pipe, the bacterial fertilizer can flow into the inside of the feeding port through the discharging pipe to be made into particles, without the need to carry the bacterial fertilizer and pour it into the inside of the feeding port for work, which is relatively labor-saving.

[0004] Based on the above patent, the vibrating sieve can perform secondary screening on the particles on the surface of the sieve. The screened particles can pass through the sieve and be collected through the discharging port. The remaining particles with unqualified sizes can be collected by using a collection box through the screening port. The rotation of the screw rod can transport the bacterial fertilizer upward. When the bacterial fertilizer is transported to a position close to the discharging pipe, the bacterial fertilizer can flow into the inside of the feeding port through the discharging pipe to be made into particles, without the need to carry the bacterial fertilizer and pour it into the inside of the feeding port for work, which is relatively labor-saving.

[0028] Specifically:

[0029] Referring to Figure 3 , Figure 4 and Figure 5, on the left and right sides of the rear end of the electric actuator 7, the driving ends are fixedly connected with mounting pipes 11. The front ends of the extrusion shafts 9 are all connected with fixed pipes 13 through strong springs 12. The rear ends of the mounting pipes 11 are all rotatably connected with adjusting rings 14. The inner walls of the adjusting rings 14 are connected with bidirectional screws 17 through gear sets. The front and rear sides of the outer walls of the bidirectional screws 17 are connected with extrusion blocks 20 through clamping groups. When the strong springs 12 at the extrusion shafts 9 are butted against the mounting pipes 11 through elastic force, rotate the adjusting ring 14 to make the gear ring 15 drive the transmission gear 16 to drive the bidirectional screw 17 to rotate, so that the bidirectional screw 17 drives the moving blocks 18 to move relatively or away from each other, and the moving blocks 18 drive the extrusion blocks 20 to extrude or release the fixed pipes 13 through the transmission rods 19. The inner walls of the adjusting rings 14 are fixedly connected with gear rings 15, and the rear ends of the bidirectional screws 17 are fixedly connected with transmission gears 16. The gear rings 15 and the transmission gears 16 are meshed. The front and rear ends of the outer walls of the bidirectional screws 17 are threadedly connected with moving blocks 18.

By replacing the extrusion shafts 9, the granulator can produce granules with different diameters to meet various different needs in the market.

[0030] Specifically:

[0031] Refer to Figure 6 , at the front and rear ends of the inner wall of the material screening bin 3, there are fixedly connected with material conveying bins 23. At the bottom end of the inner wall of the material screening bin 3, there is a screen 21 installed. The bottom end of the screen 21 is fixedly connected with a vibration motor 22. Electric conveyor belts 24 are installed on the inner walls of the material conveying bins 23. When the electric actuator 7 is started, the residues generated when the extrusion shafts 9 extrude the materials fall to the screen 21. The materials with appropriate particles pass through the screen 21 and are discharged under the cooperation of the vibration motor 22. When the electric conveyor belts 24 in the material conveying bins 23 are started, the electric conveyor belts 24 can drive the residues at the screen 21 to be discharged again through the discharge holes 25 to the receiving hopper 2, and are re-injected into the granulation bin 6 by the electric screw auger 10, so that the residue materials can be fully used, effectively recycling and utilizing the residue materials.

[0032] Working principle: Materials can be put into the receiving hopper 2, so that the electric threaded auger 10 puts the materials into the granulating bin 6 through the transmission pipe 8, and the electric transmission device 7 contains two sets of stepper motors, which can drive the extrusion shaft 9 to rotate relatively, so that the extrusion shaft 9 extrude the materials into granular materials, and when the electric transmission device 7 is started, the residues produced when the extrusion shaft 9 extrudes the materials fall into the screen 21, so that the materials with suitable particles pass through the screen 21 and are discharged with the cooperation of the vibration motor 22, and when the electric transmission belt 24 in the feeding bin 23 is started, the electric transmission belt 24 can drive the residues at the screen 21 to be discharged into the receiving hopper 2 again through the discharge hole 25, and be injected into the granulating bin 6 again by the electric threaded auger 10, so that the residue materials can be fully used, the residue materials can be effectively recycled and utilized, and non-reusable waste materials are minimized. , which improves the overall raw material utilization efficiency and helps to maximize the use of each unit of raw materials. When the strong spring 12 at the extrusion shaft 9 is docked in the mounting tube 11 through elastic force, the adjusting ring 14 is rotated to make the gear ring 15 allow the transmission gear 16 to drive the bidirectional screw 17 to rotate, so that the bidirectional screw 17 drives the moving block 18 to move relative or opposite to each other, so that the moving block 18 allows the extrusion block 20 to extrude or fall off the fixed tube 13 through the transmission rod 19, so that the fixed tube 13 can be disassembled and installed from the mounting tube 11, which is convenient for replacing the extrusion shaft 9. By replacing the extrusion shaft 9, the granulator can produce granules of different diameters to meet various different needs in the market, facilitate and quickly switch production specifications, adapt to different order requirements, improve production flexibility, reduce the wear of a single extrusion shaft, and extend the service life of the equipment.
