Description

Technical Field

[0001] This utility model relates to the field of material drying technology, specifically to a drying device for gatifloxacin mesylate raw materials. Background Technology

[0002] Gatifloxacin mesylate is a broad-spectrum antibacterial drug widely used in clinical treatment of various bacterial infections. In the pharmaceutical process, the drying of raw materials is a crucial step, as it directly affects the quality and stability of the final product. Traditional drying methods often suffer from low efficiency, high energy consumption, and uneven heating of materials, which can lead to unstable product quality and even affect the safety and efficacy of the drug.

[0003] Existing methods for drying gatifloxacin mesylate raw materials typically employ a single heat source, resulting in uneven heating of the material and prolonged drying time. Furthermore, due to the uneven heating, extended operation is required to ensure all materials reach the desired degree of dryness, increasing energy consumption. During the drying process, the material is prone to clumping due to localized overheating, affecting subsequent processing steps. Utility Model Content

[0004] In view of this, the present invention provides a drying device for gatifloxacin mesylate raw materials, which provides a heat source for the material through a heat circulation component, facilitating the drying process. At the same time, the stirring component effectively turns the material over, increasing the contact area between the material and the heat source, accelerating the evaporation rate of moisture, and shortening the drying time.

[0005] To solve the above technical problems, this utility model provides a drying device for gatifloxacin mesylate raw materials, including a fixed frame, on which a storage tank for storing materials is assumed, and a discharge valve is connected to the bottom of the storage tank. The fixed frame is equipped with a temperature control mechanism for drying gatifloxacin mesylate raw materials. The temperature control mechanism includes a heat circulation component and a stirring component used in conjunction with the heat circulation component.

[0006] The heat circulation assembly includes a shelf on the side of the fixed frame, on which a water tank is mounted. An outlet and an inlet are connected to both sides of the water tank. A heater for raising the water temperature is fixed to the top of the water tank, and a heat-conducting pipe is connected to the heater. The heat-conducting pipe circulates inside the water tank. The heat circulation assembly also includes a water circulation module for supplying and pumping water to the stirring assembly. The stirring assembly includes symmetrically arranged linear slides, on which a mounting plate is connected. A rotary joint is rotatably mounted on the mounting plate, and a stirring shaft is connected to the bottom of the rotary joint.

[0007] The heat circulation assembly, consisting of a water tank, heater, and heat pipe, heats the water and forms a closed hot water circulation system through the heat pipe, providing a stable temperature environment for the entire drying process. The water circulation module ensures the effective transfer of heat by circulating the water within the system. The stirring assembly, consisting of a linear slide block, mounting plate, rotary joint, and hollow stirring shaft, agitates the internal raw materials, promoting their drying.

[0008] The water circulation module includes a water delivery pump and a water pump mounted on a fixed frame. A water pump is connected to the water tank via a water pump pipe. The output end of the water delivery pump is connected to a first telescopic water pipe. The end of the first telescopic water pipe is connected to a water delivery pipe for supplying water to the inside of the stirring shaft. The water delivery pipe is installed inside the stirring shaft via a rotary joint. A return pipe is also connected to the rotary joint. The top end of the return pipe is connected to a second telescopic water pipe. The second telescopic water pipe is connected to the input end of the water pump. A delivery water pipe is connected between the output end of the water pump and the water tank.

[0009] Hot water is delivered to the inside of the mixing shaft through the water circulation module (water supply pump and water pump), and then the heat is transferred to the material through the mixing shaft, thereby improving the heat transfer efficiency.

[0010] The linear guide assembly includes symmetrically arranged guide grooves, within which a screw is rotatably mounted. A slider is threadedly connected to the screw, and a mounting plate is placed between the sliders. A servo motor for driving the screw rotation is fixed to the top of the guide grooves. A stirring shaft is connected to the bottom of a rotary joint via a coupling, and a stirring roller is connected to the shaft. A scraper for agitating the raw materials at the bottom is fixed to the bottom of the stirring shaft. A rotary motor for driving the rotary joint is mounted on the mounting plate.

[0011] The stirring shaft moves up and down and rotates through a rotary joint and a linear slide block, effectively preventing material from clumping and ensuring that the material is fully mixed during the drying process, further improving the uniformity of heating. The stirring rollers on the stirring shaft and the scraper at the bottom can effectively turn the material, increase the contact area between the material and the heat source, accelerate the evaporation rate of moisture, and shorten the drying time.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. A servo motor drives the screw to rotate, causing the stirring shaft to move up and down. A rotary motor drives the rotary joint to rotate, realizing automatic stirring of the stirring shaft. This mechanical method simplifies the operation process and reduces the need for manual intervention.

[0014] 2. By adjusting the parameters of the servo motor and rotary motor, the moving speed and rotation speed of the stirring shaft can be flexibly adjusted to adapt to the specific needs of different batches of materials. The stirring rollers and scrapers on the stirring shaft can effectively prevent the materials from clumping during the drying process, ensure the flowability of the materials, and improve the quality of the final product.

[0015] 3. Hot water is delivered to the inside of the mixing shaft through the water circulation module (water supply pump and water pump), and then the heat is transferred to the material through the mixing shaft, which improves the heat transfer efficiency. The mixing rollers on the mixing shaft and the scraper at the bottom can effectively turn the material, increase the contact area between the material and the heat source, accelerate the evaporation of moisture, and shorten the drying time.

[0016] 4. By directly transferring heat through hot water, the heat transfer efficiency is higher and the energy utilization is more complete compared to traditional air heating methods. Attached Figure Description

The stirring assembly 22 includes symmetrically arranged linear slides 221, a mounting plate 222 connected to the linear slides 221, a rotary joint 223 rotatably mounted on the mounting plate 222, and a stirring shaft 224 connected to the bottom of the rotary joint 223.

[0025] The heat circulation assembly 21, consisting of a water tank 212, a heater 215, and a heat pipe 216, heats the water and forms a closed hot water circulation system through the heat pipe 216, providing a stable temperature environment for the entire drying process. The water circulation module 217 enables the water to circulate within the system, ensuring effective heat transfer. The stirring assembly 22, consisting of a linear slide block 221, a mounting plate 222, a rotary joint 223, and a hollow stirring shaft 224, agitates the internal raw materials, promoting their drying.

[0026] The water circulation module includes a water delivery pump 2171 and a water pump 2172 mounted on a fixed frame 1. A water pump 2171 is connected to a water tank 212 via a water pump 2173. The output end of the water delivery pump 2171 is connected to a first telescopic water pipe 2174. The end of the first telescopic water pipe 2174 is connected to a water delivery pipe 2175 for supplying water to the inside of the stirring shaft 224. The water delivery pipe 2175 is mounted inside the stirring shaft 224 via a rotary joint 223. A return pipe 2176 is also connected to the rotary joint 223. The top end of the return pipe 2176 is connected to a second telescopic water pipe 2177. The second telescopic water pipe 2177 is connected to the input end of the water pump 2172. A delivery water pipe 2178 is connected between the output end of the water pump 2172 and the water tank 212.

[0027] Hot water is delivered to the inside of the stirring shaft 224 through the water circulation module 217 (water pump 2171 and water pump 2172), and then the heat is transferred to the material through the stirring shaft 224, thereby improving the heat transfer efficiency.
