Description

Technical Field

[0001] This utility model relates to the field of pelleting technology, specifically to a device for wet pelleting and discharge. Background Technology

[0002] In numerous industries such as pharmaceuticals, food, and chemicals, the granulation and discharge processes of materials have a crucial impact on product quality, production efficiency, and cost control. Wet granulation, a commonly used granulation process, involves adding an appropriate amount of liquid binder to the material, causing fine powder to agglomerate into granules with a specific particle size distribution and physical properties. Compared to dry granulation, it better improves the material's flowability and compressibility, and is widely used in the production of tablets, capsules, and granules. However, traditional wet granulation discharge methods have many problems and struggle to meet the ever-growing demands of modern industrial production.

[0003] For example, Chinese utility model patent application number 202222295916.7 discloses a wet high-efficiency granulator with anti-clogging function. A first motor drives a rotating shaft, multiple connecting plates, and multiple first scrapers to rotate. The first scrapers scrape the inside of the granulator, preventing material from sticking to the inside and ensuring the cleanliness and smoothness of the inner wall, facilitating the granules to fall to the discharge port. Simultaneously, the scrapers agitate the granules at the discharge port, preventing blockage and eliminating the need for time-consuming cleaning of the granulator's interior, thus improving its efficiency. However, this device still has certain shortcomings.

[0004] When feeding granules, feeding only at one position in the granulator can easily lead to material blockage, affecting subsequent discharge efficiency and consistency of granulation effect, resulting in large differences in particle size of the final product, which cannot meet the requirements of high-quality production. At the same time, when feeding materials, the spiral blades are used to assist in discharge, but it is not convenient to clean the spiral blades.

[0005] Therefore, we propose a wet pelletizing and discharge device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a wet pelleting discharge device to solve the problems mentioned in the background art.

[0014] Preferably, a fixed frame is installed on the left side of the conveying pipe, and a servo motor is installed on the left side of the fixed frame. The right side of the servo motor is connected to the conveying auger through an output shaft.

[0015] With the above structural design, starting the servo motor can drive the conveying auger to rotate, realizing efficient discharge of the granulated material, providing power support for the discharge process, ensuring that the material can be smoothly sent out from the discharge end through the conveying pipe, and improving production efficiency.

[0016] Preferably, the conveying auger and the drive shaft are connected by a connecting belt, and both the conveying auger and the drive shaft are equipped with pulleys. The drive shaft is connected to the left side of the discharge end by a bearing.

[0017] With the above structural design, the mixing component further mixes the material in the discharge end to prevent material accumulation and blockage, and assists the material to enter the conveying pipe.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-7This utility model provides a technical solution: a wet pelletizing and discharging device, including a support frame 1, a wet pelletizing machine body 2, a feeding end 3, a slot 4, a support frame 5, a mounting plate 6, a forward and reverse motor 7, a connecting block 8, a conveying plate 9, a baffle 10, a discharge end 11, a drive shaft 12, a stirring assembly 13, a conveying pipe 14, a fixing frame 15, a servo motor 16, a conveying auger 17, a connecting belt 18, a positioning bolt 19, a splicing arc assembly 20, a fixing nut 21, a connecting assembly 22, a protective frame 23, a hinge assembly 24, a positioning block 25, a threaded rod 26, a snap-fit ​​groove 27, and a limiting nut 28.

An installation plate 6 is installed on the upper rear side of the support frame 5, and a forward and reverse motor 7 is installed on the rear side of the installation plate 6. The front side of the forward and reverse motor 7 is connected to the connecting block 8 through the output shaft. The connecting block 8 is located below the conveyor plate 9, and the conveyor plate 9 is fixedly connected to the connecting block 8. When the forward and reverse motor 7 is started, the output shaft of the forward and reverse motor 7 drives the connecting block 8 to rotate. The connecting block 8 drives the conveyor plate 9 to rotate back and forth. The raw material enters the wet pellet mill body 2 from the feed ends 3 on both sides, avoiding the raw material blockage problem caused by feeding material in only one position and ensuring the consistency of pelleting effect.

[0035] A discharge end 11 is installed at the bottom of the wet granulator body 2. A drive shaft 12 is mounted inside the discharge end 11 via a bearing housing. A mixing assembly 13 is mounted on the drive shaft 12. A conveying pipe 14 is installed at the lower end of the discharge end 11. A fixing frame 15 is installed on the left side of the conveying pipe 14, and a servo motor 16 is mounted on the left side of the fixing frame 15. The right side of the servo motor 16 is connected to a conveying auger 17 via an output shaft. When the servo motor 16 is started, it drives the conveying auger 17 to rotate, pushing the granulated material to the right to achieve the discharge operation. The conveying auger 17 is installed inside the conveying pipe 14 and is connected to the drive shaft 12 via a connecting belt 18. Both the conveying auger 17 and the drive shaft 12 are equipped with pulleys. The drive shaft 12 is connected to the left side of the discharge end 11 via a bearing. When the conveying auger 17 rotates, it drives the drive shaft 12 to rotate via the connecting belt 18. The drive shaft 12 drives the mixing component 13 to rotate, which further mixes the material in the discharge end 11 to prevent material accumulation and blockage. At the same time, it assists the material in entering the conveying pipe 14, which helps with discharge. The conveying pipe 14 has an opening at the bottom, and positioning bolts 19 are installed on both the left and right sides below the opening. The positioning bolts 19 pass through the splicing arc component 20, and fixing nuts 21 are installed on the positioning bolts 19. A sealing gasket is provided on the splicing arc component 20. When it is necessary to clean the conveying auger 17, the fixing nuts 21 on the positioning bolts 19 are unscrewed, and the splicing arc component 20 is disassembled for cleaning.

Then, the positioning block 25 is rotated along the hinge component 24 so that the threaded rod 26 on the positioning block 25 abuts against the snap-fit ​​groove 27 on the lower rear side of the protective frame 23. Then, the limiting nut 28 is rotated to fix the threaded rod 26 and the positioning block 25. The positioning block 25 can protect the splicing arc component 20 and prevent it from falling off due to unstable connection.

[0037] It should be noted that the working principle of the wet granulator body 2 has been disclosed in a wet high-efficiency granulator with anti-clogging function in application number 202222295916.7. Therefore, its internal structure and working principle will not be described in detail in this application. At the same time, the material is fed in the middle of the upper part of the conveyor plate 9.

[0038] Working Principle: When using this wet pelletizing and discharging device, firstly, the forward and reverse motor 7 is started. The output shaft of the forward and reverse motor 7 drives the connecting block 8 to rotate, and the connecting block 8 drives the conveyor plate 9 to rotate back and forth. The raw material enters the wet pelletizing machine body 2 from the feed ends 3 on both sides through the conveyor plate 9, avoiding the raw material blockage problem caused by feeding at only one position, and ensuring the consistency of pelletizing effect. After the wet pelletizing machine body 2 pelletizes the material, the material falls into the discharge end 11. The servo motor 16 is started, and the servo motor 16 drives the conveyor auger 17 to rotate. The conveyor auger 17 pushes the pelletized material to the right to realize the discharge operation. When the conveyor auger 17 rotates, it drives the transmission shaft 12 to rotate through the connecting belt 18. The transmission shaft 12 drives the stirring component 13 to rotate, so that the stirring component 13 further stirs the material in the discharge end 11, preventing material accumulation and blockage, and at the same time assisting the material to enter the conveying pipe 14, which helps with discharge.

[0039] When cleaning the conveyor auger 17, unscrew the fixing nut 21 on the positioning bolt 19 and disassemble the splicing arc component 20 to clean the conveyor auger 17. The sealing gasket on the splicing arc component 20 ensures the sealing of the conveying pipe 14 during normal operation, preventing material leakage. After cleaning the conveyor auger 17, connect the splicing arc component 20 to the conveying pipe 14, and then rotate the positioning block 25 along the hinge component 24 so that the threaded rod 26 on the positioning block 25 abuts against the snap-fit ​​groove 27 on the lower rear side of the protective frame 23. Then rotate the limiting nut 28 to fix the threaded rod 26 and the positioning block 25. The positioning block 25 can protect the splicing arc component 20, preventing it from falling off due to unstable connection, thus completing a series of operations. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
