DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings: The directional nouns involved 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 according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Fig.12As shown, a drying treatment device for gliclazide includes a rapid drying device and a crushing and drying device. By setting the rapid drying device, the gliclazide raw material can be spread as much as possible, expanding its contact area with hot air, and realizing the rapid drying operation of gliclazide. By setting the crushing and drying device, the gliclazide raw material that is agglomerated after rapid drying is crushed and continues to be dried; the crushing and drying device is located at the bottom of the rapid drying device, and the rapid drying device includes a casing 1, and a hot air mechanism 3 is fixedly connected to the front of the casing 1, and the hot air mechanism 3 heats the air in the external environment and blows it into the casing 1; a material distribution mechanism 2 is fixedly connected to the left side of the casing 1, and the gliclazide raw material is lifted, taken out and dispersed from the hopper 204 by the material distribution mechanism 2, so as to prepare for the subsequent drying operation; a collecting bucket 9 is fixedly connected to the rear end of the bottom of the casing 1, and a return air duct 8 is fixedly connected to the rear of the casing 1, and the hot air is recovered by the return air duct 8, thereby realizing heat recovery, saving resources and further accelerating the drying speed of gliclazide; The other end of the return air duct 8 is fixedly connected to the top center of the casing 1, and a rotary drying mechanism 10 is rotatably connected inside the casing 1. The rotary drying mechanism 10 includes a rotary air duct 1001, which runs through the top and bottom of the casing 1 and is rotatably connected to the casing 1. The top of the rotary air duct 1001 cooperates with the return air duct 8, and a material receiving plate 1002 is fixedly connected to the outer wall of the rotary air duct 1001. A driving motor 1003 is fixedly connected to the bottom center of the casing 1 through a bracket, and the output shaft of the driving motor 1003 is fixedly connected to the bottom of the rotary air duct 1001 through a supporting frame. The gliclazide raw materials to be processed are dispersed on the plate 1002. Under the drive of the driving motor 1003, the rotating air duct 1001 drives the receiving plate 1002 to rotate slowly. The residence time of the gliclazide raw materials in the rapid drying device is controlled by controlling the rotation speed of the driving motor 1003, thereby controlling the degree of drying. After the hot air enters the interior of the casing 1, it contacts the raw materials on the receiving plate 1002, so that the moisture in the raw materials gradually evaporates, and the evaporated water vapor and hot air are gradually blown to the rear of the casing 1 and enter the rotating air duct 1001 from the return air duct 8; Fig.10 As shown, a spoiler ring 101 is fixedly connected to the right inner wall of the casing 1, and the spoiler ring 101 includes a spoiler baffle 101A and a baffle ring 101B. By setting the spoiler ring 101, hot air can be better blown to the gliclazide raw material on the receiving tray 1002, so that the heat and the raw material are in contact with each other for a longer time, and the drying speed of the raw material is further accelerated; a wind dispersion plate 306 is fixedly connected to the front inner wall of the casing 1, and the wind dispersion plate 306 can be set to allow the hot air blown in by the hot air mechanism 3 to be quickly dispersed, ensuring that the temperature at various places inside the casing 1 remains balanced, thereby ensuring that the gliclazide raw material is evenly heated and its drying quality is ensured; a fixed scraper 102 is fixedly connected to the rear inner wall of the casing 1.

[0021] like Figure 8 and Fig. 9 As shown, the upper part of the rotating air duct 1001 is an air inlet chamber 1001C, and the side wall of the air inlet chamber 1001C is fixedly provided with an air outlet opening 1001A. The lower part of the rotating air duct 1001 is an air exhaust chamber 1001D, and the side wall of the air exhaust chamber 1001D is fixedly provided with a return air hole 1001B. The hot air and evaporated water vapor enter the air inlet chamber 1001C from the return air duct 8, and are blown to the inside of the receiving tray 1002 from the air outlet opening 1001A. At this time, the heat in the hot air and water vapor can continue to heat the receiving tray 1002, further accelerating the drying speed of the gliclazide raw material, realizing heat recovery, saving resources, and because the inside of the receiving tray 1002 It is a closed environment. During the heat conduction process, the moisture in the water vapor will not have an adverse effect on the gliclazide raw material. When the hot air and water vapor fill the inside of the receiving tray 1002, they flow into the exhaust cavity 1001D from the return air hole 1001B and are discharged into the external environment from the bottom of the rotating air duct 1001; the opening of the air outlet opening 1001A is relatively large, which can ensure that the hot air and water vapor can quickly flow into the inside of the receiving tray 1002, and the opening of the return air hole 1001B is relatively small, which can ensure 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 time that the hot air and water vapor stay in the receiving tray 1002 and ensuring that the heat is fully recycled; The receiving tray 1002 is provided with multiple layers of extended splints 1002A, and material storage troughs 1002B are provided between the multiple layers of extended splints 1002A. The interior of the receiving tray 1002 is a hollow structure, and the material 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 drop it into the collecting bucket 9 at the bottom. The storage trough 1002B cooperates with the wind spoiler 101A, and the extended splint 1002A cooperates with the retaining ring 101B. By arranging a plurality of layers of material storage troughs 1002B in the carrier plate 1002, it is possible to ensure that as much gliclazide raw material as possible can be dried at the same time without expanding the volume of the casing 1. With the help of the material distribution mechanism 2, the gliclazide raw material is discharged into the material storage trough 1002B. Due to the height limit of the material storage trough 1002B, each layer of the gliclazide raw material cannot be piled up too high, thereby ensuring that the gliclazide raw material can be heated more evenly and spread more evenly. In addition, due to heat recovery, the material storage trough 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 housing 1, and a hopper 204 is fixedly connected to the bottom of the lifting pipe 201. The gliclazide raw materials are uniformly placed in the hopper 204. The top of the lifting pipe 201 is fixedly connected to a motor 202, and the output shaft of the motor 202 is fixedly connected to a lifting screw 203. The lifting screw 203 is slidably connected to the inner wall of the lifting pipe 201. The side wall of the lifting pipe 201 is fixedly provided with a multi-component material pipe 205, and the material distribution pipe 205 is matched with the storage tank 1002B one by one. The motor 202 drives the lifting screw 203 to rotate, and the gliclazide raw materials in the hopper 204 are gradually lifted and discharged from each material distribution pipe 205, and enter the storage tank 1002B, ready for rapid drying operation.

[0023] like Figure 6 As shown, the hot air mechanism 1-3 includes a ventilation pipe 301, which is fixedly connected to the front of the housing 1, and the inner wall of the ventilation pipe 301 is fixedly connected with an air filter element 302, an air dryer 303, a fan 1-304, and a heating wire 305 in sequence from the outside to the inside. By setting up the hot air mechanism 1-3, the air in the external environment can be purified, dried, and heated, and finally enter the interior of the housing 1, contact with the gliclazide raw material, and perform a drying operation.

[0024] like Fig.11 As shown, a flap valve 4 is fixedly connected to the bottom of the collecting hopper 9, a hot air mechanism 2 5 is fixedly connected to the bottom of the flap valve 4, the bottom of the hot air mechanism 2 5 is fixedly connected to the crushing and drying device, the flap valve 4 includes a valve housing 402, the inner wall of the valve housing 402 is rotatably connected to a rotating flap 403, the side wall of the valve housing 402 is fixedly connected to a motor 2 401, the output shaft of the motor 2 401 is fixedly connected to the rotating flap 403, and the flap valve 4 is provided to ensure that the hot air in the quick drying device and the hot air in the crushing and drying device are isolated, and the flow direction of each hot air is stable; the hot air mechanism 2 5 includes a feed pipe 501, a ventilation hole 503 is fixedly opened on the side wall of the feed pipe 501, a hot air assembly 502 is fixedly provided outside the ventilation hole 503, and the top of the feed pipe 501 is fixedly connected to the bottom of the valve housing 402. The hot air mechanism 2 5 can blow hot air into the crushing and drying device to perform a secondary drying operation on the gliclazide raw material.

[0025] like Fig.13 and Fig.14As shown, the crushing and drying device includes a shell 6, an air outlet 601 is fixedly opened at the lower part of the shell 6, the top of the shell 6 is fixedly connected to the feeding pipe 501, the bottom of the shell 6 is fixedly connected to the storage box 7, the upper inner wall of the shell 6 is fixedly connected to the driving motor 11, a cylinder 12 is fixedly provided inside the shell 6, a rotating roller 14 is provided inside the cylinder 12, the top of the rotating roller 14 is fixedly connected to the output shaft of the driving motor 11, the bottom of the rotating roller 14 is fixedly connected to the transmission shaft 1401, and a plurality of telescopic rollers 15 are provided inside the rotating roller 14. Driven by the second 11, the rotary roller 14 rotates in the cylinder 12, and drives the telescopic roller 15 to crush the agglomerated gliclazide raw materials. The bottom side wall of the cylinder 12 is fixedly connected with a leg, and the leg is fixedly connected to the top of the storage box 7. The top of the cylinder 12 is fixedly connected with a connecting hose 13, and the other end of the connecting hose 13 is fixedly connected to the inner wall of the shell 6. The center of the bottom of the cylinder 12 is fixedly connected with a connecting hose 2 16, and the other end of the connecting hose 2 16 is fixedly connected with a powder collecting mechanism 17, and the bottom of the powder collecting mechanism 17 is fixedly connected to the storage box 7. Since the telescopic roller 15 and the cylinder 12 are in continuous contact and collision during the crushing process, resulting in a large noise, the cylinder 12 is placed inside the shell 6, and the connection position of the cylinder 12 and other components is connected with the connecting hose 13 and the connecting hose 2 16 made of soft materials, which reduces the impact of noise on the external environment and has a good noise isolation effect.

[0026] like Fig.15 As shown, the inner wall of the cylinder 12 is fixed with multiple layers of fixed toothed discs 1201, and the bottom of each layer of fixed toothed discs 1201 is fixed with sieve teeth 1202, and the closer the sieve teeth 1202 are to the bottom of the cylinder 12, the greater the arrangement density of the sieve teeth 1202. After the agglomerated gliclazide raw material falls into the cylinder 12, it is blocked by the uppermost sieve teeth 1202, and is crushed and disintegrated under the extrusion of the telescopic roller 15 and the fixed toothed disc 1201, and falls downward into the next level of sieve teeth 1202. Since the arrangement density of the next level of sieve teeth 1202 is greater, the gliclazide raw material that is not completely crushed by the previous level of sieve teeth 1202 will be blocked by the sieve teeth 1202 of this level, and continue to be squeezed by the telescopic roller 15 and the fixed toothed disc 1201. Through the blocking of the multi-stage sieve teeth 1202 and the extrusion of the multi-stage telescopic roller 15, the agglomerated gliclazide raw material is finally completely crushed, and is subjected to hot air drying during this period.

[0027] like Fig.16 and Fig.17As shown, the telescopic roller 15 includes a fixed shell 1501, which is fixedly connected to the inside of the rotating pressure roller 14. One end of the fixed shell 1501 is slidably connected to a limiting rod 1505. One end of the limiting rod 1505 inside the fixed shell 1501 is fixedly connected to a compression spring 1504. The other end of the compression spring 1504 is fixedly connected to the fixed shell 1501. The other end of the limiting rod 1505 is fixedly connected to a mounting slide 1502. The mounting slide 1502 is rotatably connected to a roller 1503. 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 the gliclazide raw material falls into the cylinder 12, it does not necessarily fall at any particular position. Therefore, the distribution of the gliclazide raw material to be crushed near the fixed toothed disc 1201 is also uneven. By setting the grinding wheel 1503 to be retractable, the gliclazide raw material can be fully crushed to the greatest extent, and can fully contact the gliclazide raw material at various positions.

[0028] like Fig.18 , Fig.19 , Fig. 20 and Fig.21 As shown, the powder collecting mechanism 17 includes a fixed shell 1704, the top of the fixed shell 1704 is fixedly connected to the connecting hose 16, a fixed block 1704A is fixedly provided on the top of the fixed shell 1704, and a feed port 1704B is fixedly provided on the outer side of the top of the fixed shell 1704. The crushed gliclazide powder falls into the feed port 1704B from the connecting hose 16, and rushes to the bottom of the fixed shell 1704 under the influence of the hot air flow, and contacts the exhaust filter 1704C. The hot air flow can be discharged from the exhaust filter 1704C. Out, and discharged into the external environment from the outlet 601, while the gliclazide powder is blocked by the exhaust filter 1704C. With the rotation of the rotating partition 1702, the gliclazide 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 partition on the rotating partition 1702, the hot air flow can only flow downward from the feed port 1704B and be discharged from the exhaust filter 1704C, and the hot air flow will not affect the powder near the discharge port 1704D.

[0029] An exhaust filter 1704C and a discharge port 1704D are fixedly provided at the bottom of the fixed shell 1704, a discharge pipe 1701 is fixedly connected to the bottom of the discharge port 1704D, and 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 shell 1704, a transmission rod 1703 is fixedly connected to the top of the rotating partition 1702, and the transmission rod 1703 passes through the fixed shell 1704 upward, and a square coupling block is fixedly provided on the top of the transmission rod 1703, and the square coupling block cooperates with the transmission shaft 1401, and there is a certain gap between the rotating partition 1702 and the fixed shell 1704 in the axial direction , the two are clearance-matched, so by setting a square coupling block, the transmission rod 1703 and the transmission shaft 1401 can be fixed circumferentially and slide relative to each other axially, thereby ensuring that the vibration ring 1706 can reversely drive the rotating partition 1702 to produce a certain axial displacement during repeated vibrations, so that under the drive of the vibration ring 1706, the rotating partition 1702 and the fixed shell 1704 can both maintain vibration, thereby promoting the discharge of gliclazide powder; the side wall of the transmission rod 1703 is fixedly connected to a spring 1705, and the other end of the spring 1705 is fixedly connected to a vibration ring 1706, and the vibration ring 1706 is in sliding contact with the transmission rod 1703. The transmission shaft 1401 rotates, driving the transmission rod 1703 to rotate. In addition to driving the rotating partition 1702 to rotate and continuously discharging the gliclazide powder into the storage box 7, the transmission rod 1703 also drives the spring 1705 to rotate. The spring 1705 elastically drives the vibration ring 1706 to rotate. At the same time, the elastic force of the spring 1705 itself will squeeze the vibration ring 1706 downward, so that the knocking block 1706A on the vibration ring 1706 hits the fixed block 1704A, causing the fixed shell 1704 to vibrate, thereby promoting the smooth discharge of the gliclazide powder.

[0030] like Fig. 22 As shown, a knocking block 1706A is fixedly provided at the bottom of the vibration ring 1706, and the knocking block 1706A cooperates with the fixed block 1704A, and the positions of the feed port 1704B and the discharge port 1704D on the fixed housing 1704 are staggered. By staggering the positions of the feed port 1704B and the discharge port 1704D, it is prevented that the hot air flow directly carries the gliclazide powder into the external environment.

[0031] The drying method of the drying treatment equipment for gliclazide comprises the following steps: a: pouring the gliclazide raw material into the hopper 204, starting the material dividing mechanism 2, squeezing the gliclazide raw material into the rotary drying mechanism 10, and evenly dividing the gliclazide raw material in the receiving plate 1002 to prevent the accumulation of the gliclazide raw material from affecting the drying effect; b: starting the hot air mechanism 3 to blow hot air directly to the surface of the gliclazide raw material to quickly dry the gliclazide raw material; c: Hot air and high-temperature water vapor enter the inside of the receiving tray 1002 from the return air duct 8, transfer heat to the receiving tray 1002, and directly heat and dry the gliclazide raw material on the receiving tray 1002; d: starting the rotating pressing roller 14 to crush the gliclazide raw material to prevent the gliclazide raw material from hardening, expanding the contact area between the gliclazide raw material and the hot air, and starting the hot air mechanism 2 5 to continue drying the crushed gliclazide raw material; e: Start the powder collecting mechanism 17 to collect the dried gliclazide raw material into the storage box 7.

[0032] Working principle: 1. Put the gliclazide raw material into the hopper 204, and 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 with the rotation of the receiving plate 1002, so that the preparation work before rapid drying is done; 2. Clean, dry and heated hot air is blown into the housing 1 from the hot air mechanism 3 to dry the gliclazide raw material. The hot air carries the evaporated water vapor and enters the inside of the receiving tray 1002 from the return air duct 8. The heat in the hot air and water vapor heats the receiving tray 1002, and continues to heat and dry the gliclazide raw material in the storage tank 1002B. 3. As the material receiving plate 1002 rotates, the gliclazide raw material dried to a certain degree is scraped off by the fixed scraper 102 and falls into the collecting bucket 9 at the bottom of the casing 1, and continues to fall; 4. After drying, the hardened gliclazide raw material enters the cylinder 12, is blocked by the screen teeth 1202, and is crushed by the telescopic roller 15. Since the arrangement density of the screen teeth 1202 increases toward the bottom, the gliclazide is gradually and completely crushed into gliclazide powder. 5. The gliclazide powder enters the powder collecting mechanism 17 under the blowing of the hot air flow, and the hot air flow is blown out from the exhaust filter 1704C. The gliclazide powder is blocked and moves to the discharge port 1704D under the push of the rotating partition 1702, and enters the storage box 7 through the discharge pipe 1701.

[0033] The present invention provides a rapid drying device so that the gliclazide raw material can be spread as much as possible, expands its contact area with hot air, and realizes the rapid drying of gliclazide; provides a crushing and drying device so that the gliclazide raw material that is agglomerated after rapid drying is crushed and continues to be dried; and the hot air and water vapor are recovered through the return air duct 8, so that the heat in the hot air and water vapor is conducted through the receiving tray 1002 to heat the gliclazide again, thereby realizing heat recovery, saving resources and further accelerating the drying speed of gliclazide.
