[0001] This utility model relates to an integrated granulation and drying device, specifically an integrated boiling granulation and drying device for Xiao Qinglong granules, belonging to the technical field of traditional Chinese medicine granule production equipment. Background Technology

[0002] In the process of modernizing the production of traditional Chinese medicine, Xiao Qinglong granules, as a classic compound preparation of traditional Chinese medicine, have been widely used in clinical treatment due to their significant effects of relieving exterior syndromes, resolving phlegm, relieving cough and asthma. Market demand continues to grow. However, the technical bottlenecks in the granulation and drying process in its traditional production process are increasingly becoming key factors restricting the high-quality development of the industry.

[0003] In the prior art, such as the granulation and drying integrated device disclosed in announcement number CN208481725U, the raw materials for granulation immediately enter the drying section for drying after granulation, which effectively prevents granules from accumulating and sticking. The spiral drying conveyor line fully dries the formulation particles, resulting in good drying effect. However, the above-mentioned prior art solutions have the following shortcomings: When the above-mentioned granulation and drying integrated device is in use, the feeding port and the material are completely exposed to the outside environment. The material exposed to the open environment is also at risk of being contaminated by external dust and microorganisms, which seriously affects the quality and safety of the product. Utility Model Content

[0004] The purpose of this invention is to provide an integrated fluidized bed granulation and drying device for small green dragon granules, which addresses the problem that when materials are fed into the above-mentioned devices, the feeding port and the materials are completely exposed to the outside world, and the materials exposed to the open environment are at risk of being contaminated by external dust and microorganisms, seriously affecting product quality and safety.

[0005] This utility model achieves the above objectives through the following technical solution: a small green dragon granule boiling granulation and drying integrated device, including a base;

[0006] A granulation drying tank is mounted on the surface of the base. The top of the granulation drying tank is equipped with an openable lid. A material distribution plate is installed inside the granulation drying tank. A storage bin is installed on the surface of the base and on one side of the granulation drying tank. A feed pipe is installed inside the storage bin. The other end of the feed pipe extends into the granulation drying tank, and the discharge end of the feed pipe is located above the material distribution plate. A feed pump is installed on the feed pipe. A discharge pipe is located at the bottom of the granulation drying tank, and a discharge valve is installed on the discharge pipe.

[0007] As a further improvement of this utility model: the material distribution plate is a circular flat plate structure with a diameter slightly smaller than the inner diameter of the granulation drying tank, so that a certain gap is left between the material distribution plate and the inner wall of the granulation drying tank. The edge of the material distribution plate is bent upward to form a ring baffle, and multiple air holes are evenly distributed on the material distribution plate.

[0008] As a further embodiment of this utility model: a fixing plate is installed on the surface of the material distribution plate, and a T-shaped rod is slidably connected to the surface of the fixing plate. One end of the T-shaped rod is connected to a fixing block fixedly installed on the inner wall of the granulation drying tank. A spring is sleeved between the fixing block and the fixing plate on the surface of the T-shaped rod. A drive shaft is rotatably connected inside the granulation drying tank. A cam is fixed on the surface of the drive shaft. An overlapping block is fixed on the bottom surface of the material distribution plate. The cam abuts against the surface of the overlapping block. A servo motor is fixed on one side of the granulation drying tank. The output end of the servo motor extends into the granulation drying tank and is connected to one end of the drive shaft.

[0009] As a further embodiment of this utility model: a liquid storage tank is installed above the storage silo. The liquid storage tank is used to store the adhesive solution. A liquid delivery pipe extends inside the liquid storage tank. One end of the liquid delivery pipe extends into the granulation and drying tank and is connected to an atomizing nozzle installed inside the granulation and drying tank. The atomizing nozzle is located inside the upper part of the granulation and drying tank. A liquid delivery pump is installed on the liquid delivery pipe.

[0010] As a further embodiment of this utility model: an annular air duct is installed inside the granulation drying tank and above the material distribution plate. Multiple hot air nozzles are evenly distributed in a ring on the surface of the annular air duct. A hot air blower is installed on the surface of the base and on one side of the granulation drying tank. A hot air pipe is installed at the output end of the hot air blower. One end of the hot air pipe extends into the granulation drying tank and is connected to the annular air duct.

[0011] As a further embodiment of this utility model: an exhaust duct is installed on the surface of the granulation drying tank, one end of the exhaust duct is connected to an exhaust fan, and a filter is installed on the surface of the exhaust duct.

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

[0013] This utility model utilizes a combination of structures including a granulation and drying tank, a material distribution plate, air vents, a cam, an overlap block, a storage silo, a feeding pipe, a liquid delivery pipe, a hot air pipe, a ring-shaped air duct, an exhaust pipe, and a filter. The feeding system of this device directly transports material from the storage silo to the material distribution plate above the granulation and drying tank via the feeding pipe. This fully enclosed transport eliminates contact between external dust and microorganisms and the material, preventing material contamination at the source and significantly reducing product defect rates caused by contamination. Simultaneously, the liquid storage tank is connected to the atomizing nozzle via a closed liquid delivery pipe, achieving sealed transport of the adhesive solution and preventing contamination during storage and transport, ensuring the cleanliness of the granulation process and further improving product quality.

[0014] The circular flat plate structure, annular baffle, and vent design of the material distribution plate ensure that the material is evenly spread and fully contacts the hot air. The annular baffle prevents the material from accumulating at the edges, and the gap between the material distribution plate and the inner wall of the tank and the vents form a dual-channel hot air flow. Combined with the 360° annular hot air radiation of the annular air duct, it ensures that the material layer is heated evenly and avoids local over-drying or under-drying. This results in a very small fluctuation range in the moisture content of the small green dragon granules, and the product quality uniformity is effectively guaranteed.

[0015] The combination of cams, drive shafts, and overlapping blocks loosens the material, accelerates drying, and helps the material fall off quickly after drying, reducing residue, preventing scaling, and ensuring continuous and efficient drying. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Example 1

[0023] like Figures 1 to 4 As shown, a fluidized bed granulation and drying integrated device for small green dragon granules includes a base 1, a granulation and drying tank 2 mounted on the surface of the base 1, an openable tank cover 19 on the top of the granulation and drying tank 2, a material distribution plate 3 inside the granulation and drying tank 2, a storage bin 13 mounted on the surface of the base 1 and on one side of the granulation and drying tank 2, a feed pipe 15 extending inside the storage bin 13, the other end of the feed pipe 15 extending into the granulation and drying tank 2, and the discharge end of the feed pipe 15 being above the material distribution plate 3, a feed pump 14 mounted on the feed pipe 15, and a discharge pipe with a discharge valve mounted on the bottom of the granulation and drying tank 2.

[0024] The feeding system, consisting of the storage silo 13, the feed pipe 15, and the feed pump 14, allows materials to be directly transported from the storage silo 13 to the material distribution plate 3 inside the granulation and drying tank 2. This reduces material transfer steps, shortens the production cycle, and reduces losses caused by spillage and residue during material transfer, thereby improving raw material utilization and overall production efficiency. Throughout the entire conveying process, the material remains in a relatively enclosed environment, avoiding direct contact with outside air. This effectively prevents contamination of the material by external dust, microorganisms, and other pollutants, reducing product quality problems caused by material contamination and lowering the defect rate.

[0025] Furthermore, the material distribution plate 3 is a circular flat plate structure with a diameter slightly smaller than the inner diameter of the granulation drying tank 2, so that there is a certain gap between the material distribution plate 3 and the inner wall of the granulation drying tank 2. The edge of the material distribution plate 3 is bent upward to form a ring baffle, and multiple air holes 4 are evenly distributed on the material distribution plate 3.

[0026] When the material falls from the feed pipe 15 onto the material distribution plate 3, the annular baffle prevents the material from sliding to the edge and avoids material accumulation at the edge, so that it is evenly spread out, laying the foundation for subsequent processes. The gap between the material distribution plate 3 and the inner wall of the granulation and drying tank 2 not only buffers the material, but also creates a hot air guide channel. After the hot air is sprayed out from the bottom hot air nozzle 23, part of it contacts the material through the air hole 4, and the other part rises along the gap to form an annular airflow. The dual-channel design surrounds the material in all directions, improves the heat exchange efficiency, and greatly shortens the drying time.

[0027] Furthermore, a fixing plate 9 is installed on the surface of the material distribution plate 3, and a T-shaped rod 10 is slidably connected to the surface of the fixing plate 9. One end of the T-shaped rod 10 is connected to a fixing block 12 fixedly installed on the inner wall of the granulation drying tank 2. A spring 11 is sleeved between the fixing block 12 and the fixing plate 9 on the surface of the T-shaped rod 10. A drive shaft 6 is rotatably connected inside the granulation drying tank 2. A cam 7 is fixed on the surface of the drive shaft 6. An overlapping block 8 is fixed on the bottom surface of the material distribution plate 3. The cam 7 abuts against the surface of the overlapping block 8. A servo motor 5 is fixed on one side of the granulation drying tank 2. The output end of the servo motor 5 extends into the granulation drying tank 2 and is connected to one end of the drive shaft 6.

[0028] During the drying process, the cam 7 periodically squeezes the overlapping block 8, causing the material distribution plate 3 to vibrate back and forth along the axis of the T-shaped rod 10, keeping the material loose, breaking up agglomerates, increasing porosity, facilitating hot air penetration, and improving heat and mass transfer efficiency. The vibration also prevents the material from scaling on the distribution plate when the adhesive is sprayed, breaks up the slight agglomeration layer, and ensures continuous drying. After drying, the running time of the servo motor 5 is extended to enhance the vibration intensity, so that the material falls off quickly and is easy to discharge.

[0029] Example 2

[0030] Improvements based on Example 1:

[0031] Furthermore, a liquid storage tank 16 is installed above the storage silo 13. The liquid storage tank 16 is used to store the adhesive solution. A liquid delivery pipe 18 extends inside the liquid storage tank 16. One end of the liquid delivery pipe 18 extends into the granulation drying tank 2 and is connected to an atomizing nozzle 24 located inside the granulation drying tank 2. The atomizing nozzle 24 is located inside the upper part of the granulation drying tank 2. A liquid delivery pump 17 is installed on the liquid delivery pipe 18.

[0032] The atomizing nozzle 24 is installed above the granulation and drying tank 2. It uses the combined effect of gravity and airflow to atomize the adhesive solution evenly, covering the falling material from above, so that the adhesive and the material particles can fully contact each other, effectively improving the particle forming rate and uniformity. The closed infusion pipeline 18 delivers the adhesive solution in a sealed manner throughout the process, avoiding contact between the solution and the outside air, preventing microbial contamination and solvent evaporation, and meeting the hygiene standards for pharmaceutical production.

[0033] Furthermore, an annular air duct 22 is installed inside the granulation drying tank 2 and above the material distribution plate 3. Multiple hot air nozzles 23 are evenly distributed in a ring on the surface of the annular air duct 22. A hot air blower 20 is installed on the surface of the base 1 and on one side of the granulation drying tank 2. A hot air pipe 21 is installed at the output end of the hot air blower 20. One end of the hot air pipe 21 extends into the granulation drying tank 2 and is connected to the annular air duct 22.

[0034] The annular air duct 22 and the hot air nozzles 23 evenly distributed on its surface enable hot air to uniformly cover the area above the material distribution plate 3 in a 360° annular radiation manner. Compared with traditional single-sided or single-point air supply, this design eliminates the blind spot of hot air flow, ensures that the material layer is heated evenly, avoids the problem of local over-drying or under-drying, and effectively improves the uniformity of product quality.

[0035] Furthermore, an exhaust duct 25 is installed on the surface of the granulation drying tank 2, one end of the exhaust duct 25 is connected to an exhaust fan 26, and a filter 27 is installed on the surface of the exhaust duct 25.

[0036] The exhaust fan 26 provides stable suction to quickly expel moisture, exhaust gas and hot air from the granulation drying tank 2, maintain pressure balance, prevent secondary moisture absorption of materials, ensure drying effect and meet particle moisture standards. The filter 27 efficiently intercepts dust, particles and droplets and other impurities in the exhaust duct 25 to avoid polluting the workshop environment, eliminate the risk of dust explosion, protect personnel health, and meet the cleanliness requirements of pharmaceutical production.

[0037] Working principle: First, the small green dragon granules to be granulated and dried are placed into the storage bin 13. The binder solution is prepared in the liquid storage tank 16. After the device is started, the feed pump 14 starts to work, and the material in the storage bin 13 is transported to the inside of the granulation and drying tank 2 through the feed pipe 15. The material falls on the circular material distribution plate 3. Due to the obstruction of the annular baffle at the edge of the material distribution plate 3, the material will not fall from the edge and will be evenly distributed on the material distribution plate 3. At the same time, the delivery pump 17 delivers the binder solution in the liquid storage tank 16 to the atomizing nozzle 24 located above the inside of the granulation and drying tank 2 through the delivery pipe 18. The atomizing nozzle 24 atomizes the binder solution and sprays it evenly on the material in the granulation and drying tank 2, so that the material particles stick together to form granules.

[0038] Then the hot air blower 20 is started, and the generated hot air is delivered to the annular air duct 22 through the hot air duct 21. Then it is sprayed out through multiple hot air nozzles 23 evenly distributed in a ring on the surface of the annular air duct 22, passes through the air holes 4 on the material distribution plate 3, and comes into full contact with the material to dry it.

[0039] During the drying process, the servo motor 5 drives the transmission shaft 6 to rotate, and the cam 7 on the transmission shaft 6 rotates accordingly. The cam 7 continuously contacts and presses against the overlapping block 8 on the bottom surface of the material distribution plate 3, causing the material distribution plate 3 to vibrate under the guidance of the fixed plate 9 and the T-shaped rod 10. At the same time, the spring 11 on the surface of the T-shaped rod 10 plays a buffering and restoring role. In this process, it helps the material to become looser during drying, increases the contact area between hot air and material, and speeds up the drying efficiency.

[0040] Then the exhaust fan 26 continues to run, and discharges the moisture and exhaust gas generated in the granulation drying tank 2 during the drying process through the exhaust pipe 25. The filter 27 on the exhaust pipe 25 filters the dust and impurities in the exhaust gas to ensure that the discharged gas meets environmental protection requirements.

[0041] After the material is granulated and dried, the operator turns off the hot air blower 20, the infusion pump 17 and the feed pump 14 to stop the granulation and drying process. At this time, the servo motor 5 is accelerated and continues to run for a period of time to strengthen the vibration of the material distribution plate 3, so that the material overcomes the friction and adsorption between itself and the distribution plate and falls from the material distribution plate 3 to the bottom of the granulation and drying tank 2. Finally, the discharge valve on the discharge pipe at the bottom of the granulation and drying tank 2 is opened, and the material is discharged through the discharge pipe, completing the granulation and drying process of the small green dragon granules.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
