The heating boxes rotate to dry the drug from multiple angles.

The heat generated by the heating box only dries the raw materials of the medicine once, and the heat cannot be recovered and reused, resulting in low drying efficiency; 2. The medicine is very easy to clump after the drying process, resulting in uneven dryness of the raw materials, and the problem of raw materials clumping together cannot be solved, resulting in poor drying effect of the medicine.

[0019] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 12As shown, a drying device for gliclazide includes a rapid drying unit and a pulverizing drying unit. The rapid drying unit allows the gliclazide raw material to be spread out as much as possible, increasing its contact area with hot air and achieving rapid drying. The pulverizing drying unit breaks up any clumps of gliclazide that would have formed after rapid drying, allowing for further drying. The pulverizing drying unit is located at the bottom of the rapid drying unit. The rapid drying unit includes a housing 1. A hot air mechanism 3 is fixedly connected to the front of the housing 1, heating air from the outside environment and blowing it into the housing 1. A material distribution mechanism 2 is fixedly connected to the left side of the housing 1, lifting and dispersing the gliclazide raw material from the hopper 204 to prepare for subsequent drying. A collection hopper 9 is fixedly connected to the rear bottom of the housing 1, and a return air pipe 8 is fixedly connected to the rear of the housing 1, recovering hot air and thus saving resources and further accelerating the drying speed of the gliclazide. The other end of the return air duct 8 is fixedly connected to the center of the top of the casing 1. A rotary drying mechanism 10 is rotatably connected inside the casing 1. The rotary drying mechanism 10 includes a rotary air duct 1001, which passes through the top and bottom of the casing 1 and is rotatably connected to it. The top of the rotary air duct 1001 mates with the return air duct 8. A material receiving tray 1002 is fixedly connected to the outer wall of the rotary air duct 1001. A drive motor 1003 is fixedly connected to the center of the bottom of the casing 1 via a bracket. The output shaft of the drive motor 1003 is fixedly connected to the bottom of the rotary air duct 1001 via a support frame. The gliclazide raw material, dispersed and prepared for processing, is slowly rotated on the tray 1002 by the rotating air duct 1001 driven by the drive motor 1003. The residence time of the gliclazide raw material inside the rapid drying device is controlled by controlling the rotation speed of the drive motor 1003, thereby controlling the degree of drying. Hot air enters the machine casing 1 and comes into contact with the raw material on the tray 1002, causing the moisture in the raw material to gradually evaporate. The evaporated water vapor and hot air are gradually blown towards the rear of the machine casing 1 and enter the rotating air duct 1001 through the return air duct 8. Figure 10 As shown, a baffle ring 101 is fixedly connected to the inner right side of the casing 1. The baffle ring 101 includes a baffle baffle 101A and a baffle ring 101B. By setting the baffle ring 101, hot air can be better blown onto the gliclazite raw material on the material tray 1002, allowing the heat to contact the raw material for a longer time, and further accelerating the drying speed of the raw material. A diffuser plate 306 is fixedly connected to the inner front of the casing 1. By setting the diffuser plate 306, the hot air blown in by the hot air mechanism 3 can be quickly dispersed, ensuring that the temperature in all parts of the casing 1 remains balanced, thereby ensuring that the gliclazite raw material is heated evenly and ensuring its drying quality. A fixed scraper 102 is fixedly connected to the inner rear of the casing 1.

[0021] like Figure 8 and Figure 9 As shown, the upper part of the rotary air duct 1001 is the air inlet chamber 1001C, and the side wall of the air inlet chamber 1001C is fixedly provided with an air outlet 1001A. The lower part of the rotary air duct 1001 is the air exhaust chamber 1001D, and the side wall of the air exhaust chamber 1001D is fixedly provided with a return air hole 1001B. Hot air and evaporated water vapor enter the air inlet chamber 1001C from the return air duct 8 and are blown into the material receiving tray 1002 from the air outlet 1001A. At this time, the heat in the hot air and water vapor can continue to heat the material receiving tray 1002, further accelerating the drying speed of the gliclazide raw material and realizing heat recovery, saving resources. Furthermore, due to the internal structure of the material receiving tray 1002... To ensure a closed environment, the moisture in the water vapor will not adversely affect the gliclazide raw material during heat conduction. After the hot air and water vapor fill the inside of the receiving tray 1002, they flow into the exhaust chamber 1001D from the return air hole 1001B and are discharged into the external environment from the bottom of the rotating air duct 1001. The larger opening of the air outlet 1001A ensures that the hot air and water vapor can flow into the inside of the receiving tray 1002 quickly, while the smaller opening of the return air hole 1001B ensures that the hot air and water vapor fill the inside of the receiving tray 1002 as much as possible before being discharged, thereby increasing the residence time of the hot air and water vapor in the receiving tray 1002 and ensuring that the heat is fully recovered and utilized. The material receiving tray 1002 is provided with multiple layers of extended clamping plates 1002A, and a storage trough 1002B is provided between the multiple layers of extended clamping plates 1002A. The inside of the material receiving tray 1002 is a hollow structure. The storage trough 1002B cooperates with the fixed scraper 102. The fixed scraper 102 can scrape the gliclazide raw material in the storage trough 1002B and let it fall into the collection hopper 9 at the bottom. The storage trough 1002B cooperates with the wind deflector 101A, and the extended clamping plates 1002A cooperate with the baffle ring 101B. By setting up multiple storage tanks 1002B in the receiving tray 1002, it is possible to dry as much gliclazide raw material as possible at the same time without increasing the volume of the casing 1. With the help of the distribution mechanism 2, the gliclazide raw material is discharged into the storage tanks 1002B. Due to the height limitation of the storage tanks 1002B, each layer of gliclazide raw material cannot be piled up too high, ensuring that the gliclazide raw material can be heated more evenly and spread more evenly. In addition, due to heat recovery, the storage tanks 1002B can also heat and dry the gliclazide raw material.

[0022] like Figure 4 and Figure 5As shown, the material distribution mechanism 2 includes a lifting pipe 201, which is fixedly connected to the left side of the casing 1. A hopper 204 is fixedly connected to the bottom of the lifting pipe 201, where the gliclazide raw material is uniformly placed. A motor 202 is fixedly connected to the top of the lifting pipe 201, and a lifting screw 203 is fixedly connected to the output shaft of the motor 202. The lifting screw 203 is slidably connected to the inner wall of the lifting pipe 201. Multiple distribution pipes 205 are fixedly provided on the side wall of the lifting pipe 201, and each distribution pipe 205 cooperates with a storage tank 1002B. The motor 202 drives the lifting screw 203 to rotate, and the gliclazide raw material in the hopper 204 is gradually lifted and discharged from each distribution pipe 205 into the storage tank 1002B, ready for rapid drying.

[0023] like Figure 6 As shown, the hot air mechanism 3 includes a ventilation pipe 301, which is fixedly connected to the front of the casing 1. From the outside to the inside, an air filter 302, an air dryer 303, a fan 304, and a heating wire 305 are sequentially fixedly connected to the inner wall of the ventilation pipe 301. By setting up the hot air mechanism 3, air from the external environment can be purified, dried, and heated before finally entering the casing 1 to contact the gliclazide raw material for drying.

[0024] like Figure 11 As shown, a flap valve 4 is fixedly connected to the bottom of the collection hopper 9, and a second hot air mechanism 5 is fixedly connected to the bottom of the flap valve 4. The bottom of the second hot air mechanism 5 is fixedly connected to the crushing and drying device. The flap valve 4 includes a valve housing 402, a rotating flap 403 is rotatably connected to the inner wall of the valve housing 402, and a second motor 401 is fixedly connected to the side wall of the valve housing 402. The output shaft of the second motor 401 is fixedly connected to the rotating flap 403. By setting the flap valve 4, the hot air in the rapid drying device and the hot air in the crushing and drying device can be isolated, and the stability of their respective hot air flow directions can be ensured. The second hot air mechanism 5 includes a feeding pipe 501, a ventilation hole 503 is fixedly opened on the side wall of the feeding pipe 501, and a hot air assembly 502 is fixedly installed outside the ventilation hole 503. The top of the feeding pipe 501 is fixedly connected to the bottom of the valve housing 402. The second hot air mechanism 5 can blow hot air into the crushing and drying device to perform a secondary drying operation on the gliclazite raw material.

[0025] like Figure 13 and Figure 14As shown, the crushing and drying device includes a shell 6, with an air outlet 601 fixedly opened at the lower part of the shell 6. The top of the shell 6 is fixedly connected to the feeding pipe 501, and a storage box 7 is fixedly connected to the bottom of the shell 6. A second drive motor 11 is fixedly connected to the upper inner wall of the shell 6. A cylinder 12 is fixedly installed inside the shell 6, and a rotating pressure roller 14 is installed inside the cylinder 12. The top of the rotating pressure roller 14 is fixedly connected to the output shaft of the second drive motor 11, and a transmission shaft 1401 is fixedly connected to the bottom of the rotating pressure roller 14. Multiple sets of telescopic grinding wheels 15 are installed inside the rotating pressure roller 14. Driven by roller 11, the rotating pressure roller 14 rotates inside the cylinder 12, driving the telescopic grinding wheel 15 to crush the clumps of graticule raw material. Support legs are fixedly connected to the bottom side wall of the cylinder 12, and these legs are fixedly connected to the top of the storage box 7. A connecting hose 13 is fixedly connected to the top of the cylinder 12, with the other end of the hose 13 fixedly connected to the inner wall of the shell 6. A connecting hose 26 is fixedly connected to the center of the bottom of the cylinder 12, with the other end of the hose 26 fixedly connected to a powder collecting mechanism 17. The bottom of the powder collecting mechanism 17 is fixedly connected to the storage box 7. Because the telescopic grinding wheel 15 continuously contacts and collides with the cylinder 12 during the crushing process, resulting in significant noise, placing the cylinder 12 inside the shell 6 and using flexible connecting hoses 13 and 26 at the connection points between the cylinder 12 and other components reduces the noise impact on the external environment, achieving good noise isolation.

[0026] like Figure 15 As shown, the inner wall of the cylinder 12 is fixed with multiple layers of fixed toothed discs 1201. Each layer of fixed toothed discs 1201 has fixed sieve teeth 1202 at its bottom. The closer the sieve teeth 1202 are to the bottom of the cylinder 12, the greater their density. When the clumps of gliclazide material fall into the cylinder 12, they are blocked by the uppermost sieve teeth 1202 and crushed by the extensible roller 15 and the fixed toothed discs 1201. They then fall into the next level of sieve teeth 1202. Because the density of the next level of sieve teeth 1202 is greater, any gliclazide material that has not been completely crushed by the previous level of sieve teeth 1202 will be blocked by this level of sieve teeth 1202 and continue to be crushed by the extensible roller 15 and the fixed toothed discs 1201. Through the obstruction of multiple levels of sieve teeth 1202 and the crushing of multiple levels of extensible roller 15, the clumps of gliclazide material are finally completely crushed, and during this process, it is continuously dried by hot air.

[0027] like Figure 16 and Figure 17As shown, the telescopic roller 15 includes a fixed housing 1501, which is fixedly connected inside the rotating pressure roller 14. One end of the fixed housing 1501 is slidably connected to a limit rod 1505. One end of the limit rod 1505 inside the fixed housing 1501 is fixedly connected to a compression spring 1504. The other end of the compression spring 1504 is fixedly connected to the fixed housing 1501. The other end of the limit rod 1505 is fixedly connected to a mounting slide 1502. A roller 1503 is rotatably connected to the mounting slide 1502. The roller 1503 cooperates with the fixed toothed disc 1201. The mounting slide 1502 is slidably connected to the side wall of the rotating pressure roller 14. When gliclazide raw material falls into cylinder 12, it may not fall into any particular position. Therefore, the distribution of gliclazide raw material to be crushed near the fixed toothed disc 1201 is also uneven. By setting the grinding wheel 1503 to be telescopic, the gliclazide raw material can be fully crushed to the greatest extent and can make full contact with the gliclazide raw material in various positions.

[0028] like Figure 18 , Figure 19 , Figure 20 and Figure 21 As shown, the powder collection mechanism 17 includes a fixed housing 1704. The top of the fixed housing 1704 is fixedly connected to the connecting hose 16. A fixing block 1704A is fixedly provided on the top of the fixed housing 1704. An inlet 1704B is fixedly opened on the outer side of the top of the fixed housing 1704. The pulverized gliclazide powder falls from the connecting hose 16 into the inlet 1704B and is carried by the hot air flow towards the bottom of the fixed housing 1704, where it contacts the exhaust filter 1704C. The hot air flow can then be discharged from the exhaust filter 1704C. The hot air is discharged from the air outlet 601 into the external environment, while the glitz powder is blocked by the exhaust filter 1704C. As the rotating baffle 1702 rotates, the glitz powder is pushed to the discharge port 1704D, falls into the discharge pipe 1701 under the action of gravity, and finally enters the storage box 7. Due to the blocking effect of the baffle on the rotating baffle 1702, the hot air can only flow downward from the feed port 1704B and be discharged from the exhaust filter 1704C. The hot air will not affect the powder near the discharge port 1704D.

[0029] An exhaust filter 1704C and a discharge port 1704D are fixedly installed at the bottom of the fixed housing 1704. A discharge pipe 1701 is fixedly connected to the bottom of the discharge port 1704D. The bottom of the discharge pipe 1701 is fixedly connected to the storage box 7. A rotating partition 1702 is rotatably connected to the inner wall of the fixed housing 1704. A transmission rod 1703 is fixedly connected to the top of the rotating partition 1702. The transmission rod 1703 extends upward through the fixed housing 1704. A square coupling block is fixedly installed at the top of the transmission rod 1703. The square coupling block cooperates with the transmission shaft 1401. There is a certain gap between the rotating partition 1702 and the fixed housing 1704 in the axial direction. The two are fitted with a clearance, so by setting a square coupling block, the transmission rod 1703 and the transmission shaft 1401 can be circumferentially fixed and axially relative to each other. This ensures that the vibrating ring 1706 can drive the rotating partition 1702 to produce a certain axial displacement during repeated vibration. Thus, under the drive of the vibrating ring 1706, both the rotating partition 1702 and the fixed housing 1704 can maintain vibration, promoting the discharge of gliclazide powder. A spring 1705 is fixedly connected to the side wall of the transmission rod 1703, and the other end of the spring 1705 is fixedly connected to the vibrating ring 1706. The vibrating ring 1706 and the transmission rod 1703 are in sliding contact. The drive shaft 1401 rotates, driving the drive rod 1703 to rotate. In addition to driving the rotating partition 1702 to rotate and continuously discharge gliclazide powder into the storage box 7, the drive rod 1703 also drives the spring 1705 to rotate. The elasticity of the spring 1705 drives the vibrating ring 1706 to rotate. At the same time, the elastic force of the spring 1705 will squeeze the vibrating ring 1706 downward, causing the striking block 1706A on the vibrating ring 1706 to hit the fixed block 1704A, causing the fixed housing 1704 to vibrate and promote the smooth discharge of gliclazide powder.

[0030] like Figure 22 As shown, a striking block 1706A is fixedly provided at the bottom of the vibrating ring 1706. The striking block 1706A cooperates with the fixed block 1704A. The positions of the feed inlet 1704B and the discharge outlet 1704D on the fixed housing 1704 are staggered. By staggering the positions of the feed inlet 1704B and the discharge outlet 1704D, the hot airflow is prevented from directly carrying gliclazide powder into the external environment.

[0031] A drying method for a drying treatment apparatus for glützländer includes the following steps: a: Pour the gliclazide raw material into the hopper 204, start the material distribution mechanism 2, squeeze the gliclazide raw material into the rotary drying mechanism 10, so that the gliclazide raw material is evenly distributed in the receiving tray 1002, and prevent the gliclazide raw material from piling up and affecting the drying effect. b: Activate hot air mechanism 3 to blow hot air directly onto the surface of the gliclazide raw material for rapid drying; c: Hot air and high-temperature water vapor enter the interior of the material receiving tray 1002 from the return air duct 8, transfer heat to the material receiving tray 1002, and directly heat and dry the gliclazide raw material on the material receiving tray 1002. d: Start the rotating pressure roller 14 to crush the gliclazide raw material, prevent the gliclazide raw material from caking, increase the contact area between the gliclazide raw material and the hot air, and start the hot air mechanism 5 to continue drying the crushed gliclazide raw material. e: Activate the powder collection mechanism 17 to collect the dried gliclazide raw material into the storage box 7.

[0032] Working principle: 1. Place the gliclazide raw material into the hopper 204. The motor 202 drives the lifting screw 203 to squeeze the gliclazide raw material from the distribution pipe 205 into the storage tank 1002B, and slowly move it with the rotation of the receiving plate 1002. This completes the preparation work before rapid drying. 2. Clean, dry, and heated hot air is blown into the machine casing 1 from the hot air mechanism 3 to dry the gliclazide raw material. The hot air carries the evaporated water vapor into the material receiving tray 1002 through the return air pipe 8. The heat in the hot air and water vapor heats the material receiving tray 1002, and continues to heat and dry the gliclazide raw material in the storage tank 1002B. 3. As the receiving tray 1002 rotates, the gliclazide raw material that has been dried to a certain extent is scraped off by the fixed scraper 102 and falls into the collection hopper 9 at the bottom of the casing 1, and continues to fall. 4. After drying, the gliclazide raw material that has caking will enter the cylinder 12, be blocked by the sieve teeth 1202 and crushed by the extrusion roller 15. Since the density of the sieve teeth 1202 is greater towards the bottom, the gliclazide will be gradually and completely crushed into gliclazide powder. 5. Gliclazide powder enters the powder collection mechanism 17 under the blowing of hot air. The hot air is blown out from the exhaust filter 1704C, where the gliclazide powder is blocked and moved to the discharge port 1704D under the push of the rotating baffle 1702, and enters the storage box 7 through the discharge pipe 1701.

[0033] This invention achieves rapid drying of gliclazide by incorporating a rapid drying device that allows the raw material to be spread out as much as possible, increasing its contact area with hot air. A pulverizing and drying device breaks up any clumps of gliclazide that would have formed after rapid drying, allowing for continued drying. Hot air and steam are recovered through a return air duct 8, allowing the heat from the hot air and steam to be conducted back to the gliclazide via a receiving tray 1002, thus achieving heat recovery, saving resources, and further accelerating the drying speed of gliclazide.
