Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and in particular to a wet mixing granulator. Background Technology

[0002] Wet granulation technology is widely used in pharmaceuticals, chemicals, and food industries. Especially in the pharmaceutical industry, wet granulation is a key process for producing solid drugs such as granules, tablets, and capsules. The wet granulator, as the core equipment in the wet granulation process, primarily functions to mix powdered materials with an appropriate amount of liquid, forming uniform wet granules through processes such as stirring, agglomeration, and cutting, laying the foundation for subsequent drying and tableting processes. However, existing wet granulation technologies still face some technical challenges that affect granule quality and production efficiency. In traditional wet granulators, the stirring mechanism often fails to adequately and uniformly wet the powdered material, resulting in uneven wetting and affecting the uniformity and strength of the granules. Furthermore, precise control of liquid addition remains a major challenge in the wet granulation process. The amount and method of liquid addition directly affect the formation of wet granules; too much or too little liquid will lead to poor granule agglomeration or insufficient wet granule strength, thus affecting the final granule quality. Due to their high moisture content, wet pellets often exhibit strong adhesion, which can lead to poor discharge, increased downtime and material waste during production, and reduced production efficiency. In some cases, wet pellets may clog the discharge port or become stuck in mechanical parts during the discharge process, further affecting the production flow.

[0003] Patent "A Wet Mixing Granulator" (Publication No. CN209423548U, hereinafter referred to as Prior Art 1) discloses a wet granulator. Prior Art 1 cleverly designs and configures a series of components to house the stirring shaft, stirring paddle, cutting drive shaft, and cutting blade inside the material pot. This layout significantly improves the cutting and mixing efficiency of the material, ensuring the uniformity of the mixture. Furthermore, by cleverly setting the slurry feeder, the heat generated during the mixing process can be dissipated in a timely manner, thus avoiding the problem of overheating. The pot lid greatly facilitates the cleaning of residual material inside the pot. Prior Art 1 also includes auxiliary structures such as support rods, support seats, ladders, and baffles. The support rods are connected to the support seats and the machine body, ensuring the stability of the entire device. Since the wet mixing granulator is relatively large, the ladders allow workers to add materials more easily, while the baffles protect workers' safety when working at heights, preventing accidental injury.

[0004] Although the prior art 1 achieves effective mixing and granulation of materials to a certain extent through the above design, some challenges still exist when handling materials with excessive viscosity or poor flowability. When the material particles are too viscous or lack flowability, difficulties may be encountered in the discharge stage, which may affect the quality of granulation, leading to poor discharge or other related problems. Utility Model Content

[0005] In view of this, the present invention provides a wet mixing granulator to solve the problem in the prior art where the discharge process of the granulator is not smooth due to the excessive viscosity of the wet particles or the poor flowability of the material, which increases production time and difficulty.

[0033] Example 1

[0034] Please see Figure 1 This invention provides a wet mixing granulator to effectively solve problems encountered in the current technical field. Specifically, when granulating electrolytic manganese slag, the high viscosity of the slag itself poses a significant challenge. In existing granulation equipment, the high viscosity of the electrolytic manganese slag results in poor flowability during mixing, which not only affects the smoothness of the mixing process but also causes difficulties in the discharge and granulation stages. These problems not only prolong the production cycle but also increase the complexity and difficulty of operation. To address this issue, the wet mixing granulator proposed in this invention overcomes the problems of poor flowability and operational difficulties encountered in traditional granulation processes through its designed mixing section and discharge mechanism. Through this design, this invention significantly improves production efficiency and also achieves remarkable results in improving product quality.

[0035] In this embodiment, a wet mixing granulator is provided. This granulator mainly consists of two core components: a granulation tank 100 and a cover 200 hinged to the granulation tank 100. The function of the granulation tank 100 is to provide a suitable working environment for the material, while the function of the cover 200 is to seal the granulation tank 100, ensuring that the material can undergo vacuum granulation in a closed environment during the granulation process, thereby improving granulation efficiency and quality.

[0036] Further, please see Figure 1 The granulation tank 100 is designed with a feed inlet 111 at the top for convenient input of materials (electrolytic manganese slag). The interior of the granulation tank 100 is hollow, forming a dedicated cavity for granulation, namely the granulation chamber 110. The material enters the granulation chamber 110 through the feed inlet 111. The granulation chamber 110 has a spacious interior and can effectively accommodate a large amount of material. Inside the granulation chamber 110, the material undergoes a series of stirring operations, which are key steps in the granulation process. Materials, auxiliary materials, binders, etc., are added through the feed inlet 111 of the granulation tank 100, and then stirred to ensure that these components are fully mixed and form uniform particles, laying a good foundation for subsequent processing and application.

[0037] Please see Figure 1 Inside the granulation chamber 110, a high-efficiency stirring mechanism 500 is installed. Its main function is to thoroughly mix the various materials within the chamber, ensuring sufficient contact and fusion between them; and to refine the materials during stirring, preventing clumping. Furthermore, the granulation chamber 110 is equipped with a dedicated discharge mechanism 600, which effectively discharges the mixed and granulated material from the chamber. Moreover, the discharge mechanism 600 has the capability to further refine the discharged material, ensuring that the particle size meets specific production requirements, thereby improving product quality and consistency.

[0038] Please see Figure 1 and Figure 2 In this embodiment, the stirring mechanism 500 includes a stirring part 520 disposed on a hinge seat 510, which is fixed at the bottom of the granulation chamber 110. With this arrangement, the stirring part 520 can flexibly perform stirring operations through the hinge seat 510, thereby effectively and thoroughly stirring the material in the granulation chamber 110 and ensuring uniform mixing.

[0039] Furthermore, the discharge mechanism 600 is located on one side of the bottom of the granulation tank 100 and is in communication with the granulation chamber 110. When the material needs to be discharged after being fully stirred, the discharge mechanism 600 can smoothly discharge the material from the granulation chamber 110 through this communication, thereby achieving a continuous and efficient production process.

[0040] In the construction of the discharge mechanism 600, pelletizing blades 621 are provided. The function of these blades is to further refine the material discharged from the pelleting chamber 110. Through this refinement, it can be ensured that the discharged material particles meet the required particle size standards, thereby meeting the needs of subsequent processing or use.

[0041] Please see Figure 4 The cover 200 is equipped with not only a first auxiliary hole 210 but also a second auxiliary hole 220. These two auxiliary holes are connected to the vacuum unit and the liquid addition mechanism, respectively, ensuring communication with the granulation chamber 110. The presence of the first auxiliary hole 210 and the second auxiliary hole 220 allows the vacuum unit to effectively set the granulation chamber 110 to a vacuum operating state, while effectively venting the gas generated during material mixing. This design not only helps maintain the vacuum level inside the granulation chamber 110 but also promptly removes waste gas generated during mixing, ensuring a clean working environment and stable material quality.

[0042] Considering the potential differences in material viscosity and moisture content during each mixing operation, especially when the material is relatively dry, a liquid addition mechanism is installed on the machine cover 200 to ensure proper control of viscosity and moisture content, thereby guaranteeing material stability and uniformity. This mechanism can add an appropriate amount of liquid to the material during mixing, effectively adjusting the viscosity and moisture content to ensure consistent material quality during mixing and provide a more uniform material for subsequent processing steps.

[0043] Further, please see Figure 1 An auxiliary pelletizing mechanism is also provided inside the pelletizing tank 100. This mechanism is a standard feature in wet pelletizing machines and is used to cut the material inside the pelletizing tank 100 into smaller pieces during the mixing process.

[0044] Please see Figure 1 and Figure 3In this embodiment, a mounting part 300 is provided on the body of the granulation tank 100. This mounting part 300 is used to mount the lid 200. This design allows the lid 200 to be easily opened and closed on the granulation tank 100. To ensure the airtightness of the granulation tank 100 during use, a sealed structure is formed between the lid 200 and the granulation tank 100 when they are tightly closed. Furthermore, to further improve the sealing effect, the lid 200 is also equipped with sealing strips. These sealing strips are in close contact with the body of the granulation tank 100 when the lid 200 is closed, thereby ensuring that the internal environment of the granulation tank 100 is not disturbed by external factors, maintaining the airtightness and cleanliness of the granulation tank 100.

[0045] In this embodiment, the cover 200 is hingedly connected to the mounting portion 300 on the tank body via a connecting plate 310. The mounting portion 300 is also equipped with a lifting cylinder 320, which enables the automatic opening and closing of the cover 200 through its extension and retraction. Specifically, the piston rod 321 of the lifting cylinder 320 is hinged to the connecting plate 310; one end of the connecting plate 310 is fixedly connected to the cover 200, while the other end is hinged to the mounting portion 300 via a hinge plate, thus enabling the cover 200 to open or close via the hinge. When the piston rod 321 of the lifting cylinder 320 extends, the cover 200 opens accordingly; conversely, when the piston rod 321 of the lifting cylinder 320 retracts, the cover 200 closes. This design makes the opening and closing of the cover 200 very convenient and automated, greatly improving operational efficiency and ensuring the stability and safety of the operation process.

[0046] Please see Figure 3 In this embodiment, the granulation tank 100 is further equipped with a locking mechanism 400. When the lid 200 is engaged with the granulation tank 100, the locking mechanism 400 ensures a tight lock between the lid 200 and the granulation tank 100. This design creates a sealed environment between the granulation tank 100 and the lid 200, effectively preventing material leakage or intrusion of external impurities during the granulation process, thus ensuring the smooth operation of the granulation process and the quality of the granulated product.

[0047] In this embodiment, the stirring unit 520 includes a stirring head 521 that is firmly connected to the hinge seat 510. Furthermore, a series of stirring blades 522 and scraper blades 523 are evenly distributed around the periphery of the stirring head 521. These stirring blades 522 and scraper blades 523 are spaced at a uniform angle to ensure uniformity and efficiency in stirring and cutting materials. The stirring blades 522 effectively stir and cut the material through their rotational motion, thereby achieving the purpose of granulation. The scraper blades 523 prevent material from adhering to the side walls and bottom of the granulation chamber 110 during the granulation process, ensuring smooth granulation.

[0048] Please see Figure 2 To ensure the stability and reliability of the mixing blades 522 and scraper blades 523, they are connected to the mixing head 521 via a series of mounting rods 524. These mounting rods 524 not only ensure the correct positioning of the mixing blades 522 and scraper blades 523, but also allow them to maintain appropriate flexibility during operation. Furthermore, multiple mixing blades 522 and scraper blades 523 are designed, which improves the efficiency of mixing and scraping, ensuring that the material is adequately processed during granulation.

[0049] In other embodiments, to achieve better granulation results, a granulation mechanism is also provided on the stirring mechanism 500 within the granulation chamber 110. This granulation mechanism uses a cutting section to perform high-speed rotary cutting of the material, achieving granulation and refining effects. This design not only improves the efficiency of material processing but also, by precisely controlling the cutting speed and time, yields particles with uniform particle size distribution, thereby further improving the quality of the final product.

[0050] Please see Figure 1In this embodiment, a discharge port 112 is provided on one side of the bottom of the granulation tank 100 to facilitate material discharge. The discharge mechanism 600 communicates with the granulation chamber 110 through this discharge port 112, ensuring that the material can be smoothly transferred from the granulation chamber 110 to the discharge mechanism 600. Furthermore, a gate 112 for controlling the opening and closing of the discharge port 112 is provided at the location where the discharge mechanism 600 communicates with the granulation chamber 110. This gate 112 is designed to precisely control the material discharge process when needed, ensuring the smoothness and efficiency of the entire granulation process. After the material mixing and granulation operations are successfully completed, the operator can control the opening of the gate 112 to allow the material to be discharged through the discharge port 112. During the material discharge process, the scrapers 523 in the mixing mechanism 500 play a crucial role, pushing and squeezing the material, causing it to be squeezed out wave after wave through the discharge port 112. This wave-like discharge method not only improves discharge efficiency but also reduces material loss during the discharge process, ensuring full utilization of the material. Through this design, the present invention achieves continuous and efficient material discharge, greatly improving the production efficiency and material utilization rate of the entire pelleting process.

[0051] In the discharge mechanism 600 of this embodiment, the interior is designed as a hollow structure, thus forming a discharge chamber 610 for discharging materials. Inside the discharge chamber 610, a cutting shaft 620 for cutting materials is specially provided; simultaneously, a drive device for driving the cutting shaft 620 is correspondingly arranged outside the discharge chamber 610. A pelletizing blade 621 is mounted on the cutting shaft 620 to facilitate cutting the material. To further improve the pelletizing effect and avoid poor results during the pelletizing process, this embodiment uses the pelletizing blade 621 to perform a second refining process on the material. Since the material continuously enters the discharge chamber 610 through the discharge port of the tank in waves, the pelletizing blade 621 has sufficient time to perform a second refining operation on these continuously discharged materials, thereby ensuring that the particle size of the material meets the expected standard.

[0052] Furthermore, the canopy at the discharge port of the tank can be opened or closed as needed to facilitate the smooth discharge of materials; conversely, it can be closed when material discharge is not required, thus effectively sealing the granulation chamber 110. This design not only ensures smooth material discharge but also guarantees sealing during the granulation process, thereby improving the efficiency and quality of the entire granulation process.

[0053] In this embodiment, a granule outlet 640 is provided at the bottom of the discharge chamber 610, and the granule outlet 640 is interconnected with the discharge chamber 610. After the material is discharged through the tank outlet 112, it is cut by the pelletizing blade 621 to form granular material, which is then discharged through the granule outlet 640. To further ensure the material refinement effect, a filter screen is added at the granule outlet 640, which can effectively filter out larger particles that do not meet the requirements, ensuring the uniformity of the material. In addition, a blower mechanism is specially provided at the top of the discharge chamber 610. The function of this blower mechanism is to help remove material that may be blocked on the filter screen by blowing air, thereby avoiding the decrease in production efficiency caused by filter screen blockage. This design not only improves the efficiency of material handling, but also ensures the smooth operation of the entire production process.

[0054] Please see Figure 1 In this embodiment, a drive mechanism is also configured; this drive mechanism consists of a motor and a reducer 720, wherein the motor and the reducer 720 are closely connected by a transmission connection to ensure efficient power transmission. Furthermore, the reducer 720 is also connected to the hinge seat 510 by a transmission connection. In this way, through the coordinated work of this drive mechanism, the stirring unit 520 can be effectively driven to perform continuous and uniform stirring operations, thereby ensuring the stability of the stirring process and the uniformity of the stirring effect.

[0055] In this embodiment, a frame structure is also configured to provide a stable support platform. The frame not only mounts the granulation tank 100 but also the aforementioned drive mechanism. The frame itself consists of support legs 810 and a support panel 820. The support legs 810 provide sufficient strength and stability, while the support panel 820 provides a flat and robust mounting surface for the granulation tank 100 and the drive mechanism. This design not only ensures the stable operation of the entire device but also facilitates maintenance and operation, improving the device's efficiency and safety.
