Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical machinery and automated production technology, and in particular to a granule drying, recovery and buffering production line. Background Technology

[0002] In the granule production field, drying is a crucial step, and its technological development has a profound impact on the entire granule industry. As market demands for granule quality and production efficiency continue to rise, drying technology is also constantly evolving. Efficient drying technology ensures stable granule quality, meets the needs of various application scenarios, improves production efficiency, reduces production costs, and thus enhances a company's market competitiveness. In many industries, including pharmaceuticals and food, superior granule drying technology helps guarantee product safety and efficacy, promoting the healthy development of the industry.

[0003] Traditional granule drying processes typically employ single-stage drying equipment. A common method involves placing the granules in a standard drying chamber and drying them through hot air circulation. While this method achieves the drying objective to some extent, the process is slow and makes precise control of the drying degree difficult. Furthermore, the screening and recovery of dried granules often rely on manual operation or simple mechanical screening, which is not only inefficient but also prone to errors.

[0004] Traditional granule drying methods suffer from low drying efficiency and difficulty in guaranteeing drying quality. Single-stage drying equipment is slow and cannot meet the needs of large-scale production; two-stage dryers lack uniformity and comprehensiveness in drying, resulting in inconsistent granule quality. Meanwhile, traditional screening and recycling methods are inefficient and prone to error, failing to achieve efficient recycling of granules. Utility Model Content

It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] This utility model discloses a granule drying, recovery, and buffering production line, such as... Figure 1 and Figure 2 As shown, the system includes a drying unit 1, a screening unit 2, a buffer unit 3, a recycling unit 4, and a final mixer 7. The drying unit 1 preheats, dries, and cools the granules. The screening unit 2 separates the qualified and unqualified mixtures; the qualified mixtures enter the buffer unit 3, while the unqualified mixtures are recycled by the recycling unit 4. The buffer unit 3 buffers the qualified mixtures before sending them to the final mixer 7, where they are finally packaged. This process improves the drying efficiency and quality of the granules and enables the recycling of unqualified mixtures. This is because the three-stage fluidized bed dryer 11 integrates preheating, drying, and cooling, efficiently completing these three processes sequentially. The screening unit 2 provides precise screening, and the recycling unit 4 allows for the reuse of unqualified materials.

[0026] Specifically, the drying device 1 includes a three-stage fluidized bed dryer 11. The three-stage fluidized bed dryer 11 consists of a preheating chamber, a drying chamber, and a cooling chamber. The preheating chamber typically uses hot air circulation to preheat the granules, ensuring they reach a suitable temperature before entering the drying chamber, thus improving subsequent drying efficiency. The hot air in the preheating chamber can be supplied by a gas-fired or electrically heated hot air furnace. The drying chamber is the core drying area, where a high-speed hot airflow keeps the granules in a fluidized bed state, significantly increasing the contact area between the granules and the hot air, accelerating moisture evaporation. The cooling chamber is used to rapidly cool the dried granules, preventing deterioration due to excessive temperature. The cooling chamber can be air-cooled or water-cooled. A ramp conveyor 5 is installed on one side of the drying device 1, responsible for transporting the granules into the drying device 1. The ramp conveyor 5 typically consists of a conveyor belt, a drive motor, and a support frame. The conveyor belt is made of wear-resistant and high-temperature-resistant rubber to meet the conveying requirements of the granules. The drive motor provides power to rotate the conveyor belt, smoothly transporting the granules into the drying unit 1. The angle of the inclined conveyor 5 can be adjusted according to the actual site and conveying requirements to ensure smooth conveying.

[0027] Specifically, the screening device 2 includes a screening machine 21, which contains a three-layer square vibrating screen. The square vibrating screen consists of a screen frame, screen mesh, and a vibrating motor. The screen frame is made of stainless steel, offering good corrosion resistance and strength. The screen mesh has different apertures to meet different screening requirements; the three layers of screen mesh allow for progressive screening, removing larger or smaller granules. The vibrating motor is mounted on the screen frame, causing the granules to continuously bounce on the screen mesh, improving screening efficiency. The screened, qualified mixture enters the buffer device 3 through the discharge port.

[0028] Specifically, the buffer device 3 includes multiple buffer tanks 31, each with a feed inlet at its top. These inlets are connected to the discharge outlet of the screening machine 21 via pipelines. The buffer tanks 31 are generally cylindrical, made of stainless steel, and possess good sealing and corrosion resistance. An observation window is provided on the tank body for easy monitoring of the material inside. A valve can be installed at the feed inlet to control the inflow of material. Multiple buffer tanks 31 can be combined according to actual production needs to meet different buffering requirements.

[0029] Specifically, the recycling device 4 includes a weighing device 41 and a fine sand recycling tank 42, which are interconnected with the weighing device 41. The weighing device 41 can be an electronic scale, capable of accurately weighing the substandard mixture. The fine sand recycling tank 42 is used to collect the substandard mixture for subsequent reuse.

[0030] Specifically, a cyclone dust collector 6 is installed between the screening device 2 and the recovery device 4, and multiple cyclone dust collectors 6 are installed. The cyclone dust collector 6 consists of a cylinder, an air inlet, an exhaust outlet, and a dust discharge outlet. When dust-laden gas enters the cylinder at a high speed through the air inlet, it rotates within the cylinder. The dust is thrown against the cylinder wall by centrifugal force and then falls down the cylinder wall to the dust discharge outlet. The purified gas is discharged from the exhaust outlet. Multiple cyclone dust collectors 6 can be used in series to improve the dust removal efficiency.

[0031] Specifically, a mixing machine 7 and a packaging process 8 are also installed on one side of the buffer device 3. The mixing machine 7 and the packaging process 8 are used to process and package the powder. The mixing machine 7 can fully and evenly mix the qualified mixture, ensuring the stability of product quality. The packaging process 8 can adopt different packaging methods according to different product requirements, such as bagging, bottling, etc.

[0032] Specifically, a negative pressure system 9 is installed between the buffer device 3 and the main mixer 7, which is used to transport the powder into the main mixer 7. The negative pressure system 9 consists of a vacuum pump, pipes, and valves. The vacuum pump generates negative pressure, causing the powder to be drawn into the main mixer 7 through the pipes. The pipes are made of wear-resistant and corrosion-resistant materials, and the valves can control the conveying speed and flow rate of the powder.

[0033] The implementation principle of this embodiment is as follows: This production line improves the drying efficiency and quality of granules through a three-stage fluidized bed dryer 11; a screening device 2 accurately screens out qualified and unqualified mixtures; a recycling device 4 recycles unqualified materials; a buffer device 3 buffers qualified materials and conveys them to the main mixer 7 through a negative pressure system 9; and finally, the packaging process 8 is performed. The entire production line achieves automation and high efficiency in granule drying, recycling, and buffering, greatly improving production efficiency, ensuring product quality, and reducing production costs. Compared with traditional granule drying methods, this represents a significant improvement and enhancement.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
