Description

Technical Field

[0001] This invention relates to the field of pharmaceutical intermediate storage technology, and more particularly to a drying and storage device for fluorocephalosporin pharmaceutical intermediate. Background Technology

[0002] Fluoxetine, as an important pharmaceutical intermediate, has wide applications in the pharmaceutical industry. The drying and storage processes are crucial in its production, directly affecting the product's quality and stability.

[0003] Chinese Patent CN220097244U discloses an intermediate drying and storage device, including a storage tank and a discharge pipe. The discharge pipe is located at the bottom of the storage tank. The device also includes a mounting frame mounted on the storage tank, a feeding assembly mounted on the mounting frame and connected to the inlet of the storage tank, and a curved partition disposed inside the storage tank. The front and rear ends of the curved partition are connected to the inner wall of the storage tank. The upper surface of the storage tank and the upper side of the inner wall form a curved feeding channel. Although this patent can dry and store intermediates, when the discharge pipe is opened to discharge the intermediates, although the remaining intermediates can block the outlet of the storage tank to prevent external air from entering, because the intermediates are in powder form and there are gaps between them, some moisture in the air can still enter the storage tank, causing some intermediates to become damp, thus affecting the storage effect.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a drying and storage device for fluorocephalosporin pharmaceutical intermediates is proposed, which can separate the discharged intermediates from the remaining intermediates, prevent moisture from entering the storage tank and causing the remaining intermediates to become damp, and improve the storage effect of the intermediates. Summary of the Invention

[0005] To overcome the drawbacks of the intermediates being in powder form with gaps between them, allowing some moisture from the air to enter and cause some intermediates to become damp, thus affecting the storage effect, this invention provides a fluorocephalosporin pharmaceutical intermediate drying and storage device that separates the discharged intermediates from the remaining intermediates, preventing moisture from entering the storage tank and causing the remaining intermediates to become damp, thereby improving the storage effect of the intermediates.

[0006] This invention is achieved through the following technical solution:

[0007] A drying and storage device for a cephalosporin pharmaceutical intermediate includes a frame and a storage tank fixedly connected to the top of the frame. A suction pump is installed on the top of the frame. A cylinder is vertically fixedly connected to the frame, and a weighing pan is installed inside the cylinder. An electrically operated opening and closing plate is installed on the weighing pan. The device also includes a drying assembly installed on the storage tank, connected to the discharge end of the suction pump for conveying and drying the intermediate. A discharge pipe is connected to the bottom of the cylinder, and an electrically controlled valve is installed on the discharge pipe. A hopper is fixedly connected circumferentially inside the cylinder, and a fixed perforated plate is fixedly connected circumferentially inside the hopper. The top of the fixed perforated plate... A rotating perforated disc is rotatably connected to the cylinder, and a drive motor is installed on the cylinder body. The output shaft of the drive motor is circumferentially connected to the rotating perforated disc via a synchronous belt assembly. The drive motor is used to drive the rotating perforated disc to rotate, and the rotation of the rotating perforated disc opens and closes the fixed perforated disc. When it is opened, the intermediate body falls downward into the weighing pan. When it is closed, the intermediate body stops falling downward, so that the discharged intermediate body is separated from the remaining intermediate body. Then the intermediate body on the weighing pan is completely discharged. A conveying assembly is provided between the cylinder body and the collecting hopper to drive the intermediate body to be conveyed downward evenly.

[0008] Further explanation: The conveying assembly includes a fixed plate fixed to the inside of the hopper, and a spiral conveying plate that rotates through the fixed plate and contacts the inside of the hopper, which is used to drive the intermediate body to move downward for conveying. A stepper motor is installed on the cylinder, and the output shaft of the stepper motor is connected to the spiral conveying plate through a synchronous belt assembly.

[0009] Further explanation: The drying assembly includes a fixed pipe that is fixedly connected to the storage tank. The end of the fixed pipe is connected to the discharge end of the suction pump. An opening is opened on the right side of the bottom of the fixed pipe for discharging the dried intermediate. An exhaust pipe is fixedly connected to the storage tank, and the end of the exhaust pipe is fixedly connected to the fixed pipe. An air inlet pipe is fixedly connected to the storage tank, and the end of the air inlet pipe is fixedly connected to the fixed pipe. A spiral shaft is rotatably connected between the fixed pipe and the storage tank for driving the intermediate to move to the right for uniform drying. A servo motor is installed on the storage tank, and the end of the output shaft of the servo motor is fixedly connected to the end of the spiral shaft. A blocking component is provided on the fixed pipe for blocking the intermediate.

[0010] Further explanation: The blocking assembly includes a frame symmetrically fixed to the inside of the fixed tube, and a microporous filter membrane is fixed to the inside of the frame. The microporous filter membrane corresponds to the exhaust pipe and the intake pipe and is used to block the intermediate body.

[0011] To further explain, the drying and storage equipment for fluorocephalosporin pharmaceutical intermediates also includes an agitation component. The agitation component includes a rotating frame that is rotatably connected to the storage tank. Heating rods are symmetrically fixed on the rotating frame for further drying of the intermediate. A drive component is provided between the rotating frame and the storage tank to drive the rotating frame to rotate.

[0012] Further explanation: the drive assembly includes a worm gear fixedly mounted on a rotating frame, a dual-axis motor mounted on the storage tank, and a worm gear meshing with the worm gear fixedly connected to the end of the output shaft of the dual-axis motor.

[0013] Further explanation: the drying and storage equipment for fluorocephalosporin pharmaceutical intermediates also includes a sealing assembly. The sealing assembly includes evenly spaced, embedded airbags fixed to the top circumferential direction of a fixed perforated disk for sealing the holes of the rotating perforated disk. Air guide tubes are connected between the airbags and are fixedly inserted through the fixed perforated disk. A fixed frame is fixedly connected to the inner side of the cylinder. A cylinder is fixedly connected to the inner side of the fixed frame. A piston rod is slidably connected to the inner side of the cylinder. A connecting pipe fixedly connected to the air guide tube is connected to the cylinder. A cylinder is fixedly connected to the inner side of the fixed frame. The end of the cylinder's telescopic rod is fixedly connected to the end of the piston rod.

[0014] To further explain, the fluorocephalosporin pharmaceutical intermediate drying and storage equipment also includes a corrugated hood connected between the discharge end of the hopper and the inlet end of the discharge pipe, used to block the floating intermediate.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. After the intermediate is dried by hot air, it is discharged into the storage tank for storage. The rotating and fixed perforated discs block the intermediate. When the intermediate is needed, the drive motor is started to connect the rotating and fixed perforated discs. The intermediate in the storage tank is discharged into the weighing pan through the rotating and fixed perforated discs for weighing. When the discharged intermediate reaches the required weight, the rotating perforated disc rotates back to its original position and closes. Then, the electric opening and closing plate and the electric control valve are activated to discharge the intermediate on the weighing pan. Due to the action of the fixed and rotating perforated discs, the discharged intermediate is separated from the remaining intermediate, which can prevent moisture from entering the storage tank and causing the remaining intermediate to become damp, thereby improving the storage effect of the intermediate.

[0017] 2. Under the action of the heating rod, whenever the intermediate is stored for a long time, the heating rod is activated to heat it. At the same time, the heating rod rotates to stir and dry the intermediate, which can prevent water droplets from forming in the storage tank in the southerly wind environment, thus ensuring the dryness of the intermediate.

[0018] 3. Under the action of the airbag, whenever the rotating perforated disk is not connected to the fixed perforated disk, the airbag expands to seal the holes of the rotating perforated disk, which can prevent the intermediate body from entering the gap between the rotating perforated disk and the fixed perforated disk and affecting the rotation of the rotating perforated disk, thereby ensuring the smooth rotation of the rotating perforated disk.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: A drying and storage device for the pharmaceutical intermediate fluorocephalosporin. Please refer to [link / reference]. Figures 1-7 As shown, the system includes a frame 1 and a storage tank 2 vertically fixed to the top center of the frame 1. A suction pump 3 is installed on the top left side of the frame 1, which can pump the intermediate material. A cylinder 4 is vertically fixed to the lower center of the frame 1. A weighing pan 5 is installed on the lower part of the inner side of the cylinder 4. An electric opening and closing plate 6 is installed on the lower part of the weighing pan 5. The electric opening and closing plate 6 can control the discharge of the intermediate material on the weighing pan 5. The electric opening and closing plate 6 consists of a circular plate and a micro motor, wherein the circular plate is rotatably connected to the weighing pan. On the lower left side of the weighing pan 5, a circular plate contacts the inner side of the weighing pan 5. A micro motor is installed on the outer left side of the weighing pan 5, and the output shaft end of the micro motor is fixedly connected to the shaft of the circular plate. The system also includes a discharge pipe 7, an electric control valve 8, an air supply pump 9, a three-way pipe 10, a collection hopper 11, a conveying assembly, a fixed perforated disc 13, a rotating perforated disc 14, a drive motor 15, and a drying assembly. A drying assembly is installed on the upper part of the storage tank 2. The drying assembly is connected to the discharge end of the suction pump 3. When the drying assembly operates, the material is dried... The dry assembly enables the conveying and drying of intermediate materials. A discharge pipe 7 is connected to the bottom center of the cylinder 4, and an electrically controlled valve 8 is installed at the bottom of the discharge pipe 7. A hopper 11 is fixedly connected circumferentially to the upper inner side of the cylinder 4. A fixed perforated disc 13 is fixedly connected circumferentially to the middle inner side of the hopper 11. A rotating perforated disc 14 is rotatably connected to the top of the fixed perforated disc 13. A drive motor 15 is installed on the upper right side of the cylinder 4. The output shaft of the drive motor 15 is circumferentially connected to the outer surface of the rotating perforated disc 14 via a synchronous belt assembly. Next, the drive motor 15 is used to drive the rotating perforated disk 14 to rotate. The rotating perforated disk 14 opens and closes the fixed perforated disk 13. When it is opened, the intermediate body falls downward into the weighing disk 5. When it is closed, the intermediate body stops falling downward, so that the discharged intermediate body is separated from the remaining intermediate body. Then the intermediate body on the weighing disk 5 is completely discharged. A conveying component is provided between the cylinder 4 and the collecting hopper 11. When the conveying component is operating, the conveying component can drive the intermediate body to be conveyed downward evenly.

[0033] Please see Figure 3 and Figure 4As shown, the conveying assembly includes a stepper motor 12, a fixed plate 121, and a screw conveyor plate 122. The fixed plate 121 is fixedly connected to the lower left side of the hopper 11, and the screw conveyor plate 122 is rotatably connected to the right side of the fixed plate 121. The screw conveyor plate 122 contacts the lower inner side of the hopper 11. When the screw conveyor plate 122 rotates, it can drive the intermediate body to move downward for conveying. The stepper motor 12 is installed on the upper left side of the cylinder 4. The output shaft of the stepper motor 12 is connected to the lower part of the screw conveyor plate 122 through a synchronous belt assembly.

[0034] Please see Figure 6 and Figure 7 As shown, the drying assembly includes a fixed pipe 16, an air inlet pipe 161, an exhaust pipe 162, a servo motor 163, a spiral shaft 164, and a blocking assembly. The fixed pipe 16 is horizontally fixedly connected to the upper part of the storage tank 2. The left end of the fixed pipe 16 is connected to the discharge end of the suction pump 3. An opening 165 is opened on the right side of the bottom of the fixed pipe 16 for discharging the dried intermediate. The exhaust pipe 162 is fixedly connected to the upper front side of the storage tank 2, and the rear end of the exhaust pipe 162 is fixedly connected to the front side of the fixed pipe 16. The air inlet pipe 161 is fixedly connected to the upper rear side of the storage tank 2, and the front end of the air inlet pipe 161 is fixedly connected to the rear side of the fixed pipe 16. The spiral shaft 16 is rotatably connected between the right side of the fixed pipe 16 and the upper right side of the storage tank 2. 4. When the spiral shaft 164 rotates, it can drive the intermediate body to move to the right for uniform drying. A servo motor 163 is installed on the upper part of the outer right side of the storage tank 2. The output shaft end of the servo motor 163 is fixedly connected to the right end of the spiral shaft 164. A blocking component is provided on the fixed tube 16. When the blocking component operates, it can block the intermediate body. The blocking component includes a frame 166 and a microporous filter membrane 167. The frame 166 is symmetrically fixed to the inner side of the fixed tube 16. The microporous filter membrane 167 is fixed to the inner side of the front and rear sides of the frame 166. The front microporous filter membrane 167 corresponds to the exhaust pipe 162, and the rear microporous filter membrane 167 corresponds to the air inlet pipe 161. The microporous filter membrane 167 can block the intermediate body.

[0035] Initially, an external hot air pump is connected to the inlet pipe 161, and an external discharge pipe is connected to the exhaust pipe 162. Nitrogen is supplied to the air supply pump 9. First, the suction end of the suction pump 3 is placed inside the fluorocephalosporin pharmaceutical intermediate. Then, the servo motor 163 is started, driving the spiral shaft 164 to reverse. Simultaneously, the external hot air pump is started, discharging hot air into the inlet pipe 161. The hot air in the inlet pipe 161 passes through the rear microporous filter membrane 167 and is discharged into the fixed pipe 16. As the hot air continues to flow, it flows forward, passing through the front microporous filter membrane 167 and being discharged into the exhaust pipe 162. The suction pump 3 is then started, drawing the intermediate into the fixed pipe 16 where it contacts the spiral shaft 164. The spiral shaft 164 reverses, causing the intermediate to move to the right for transport. During this rightward movement, the intermediate comes into contact with the hot air. The intermediate material moving to the right is dried by blowing air. The microporous filter membrane 167 can block the intermediate material, preventing it from entering the exhaust pipe 162 and the air inlet pipe 161. As the intermediate material continues to move to the right and reaches above the opening 165, the dried intermediate material falls down through the opening 165 into the storage tank 2 for storage. The intermediate material in the storage tank 2 falls into the collection hopper 11 and is blocked by the fixed porous disc 13 and the rotating porous disc 14. When the storage tank 2 contains an appropriate amount of dried intermediate material, the suction pump 3 is turned off, and the intermediate material stops being discharged into the storage tank 2. The storage tank 2 continues to store the dried intermediate material. When the required amount of intermediate material needs to be taken out for use, the stepper motor 12 is first started in reverse. The reverse rotation of the stepper motor 12 is driven by the synchronous belt assembly. The screw conveyor plate 122 is reversed, and the drive motor 15 is started. The drive motor 15 drives the rotating perforated disk 14 to rotate through the synchronous belt assembly. When the rotating perforated disk 14 rotates and corresponds to the hole of the fixed perforated disk 13, the rotating perforated disk 14 and the fixed perforated disk 13 are connected. The drive motor 15 is then turned off. At this time, the dried intermediate in the storage tank 2 falls into the cylinder 4 through the rotating perforated disk 14 and the fixed perforated disk 13. The intermediate in the cylinder 4 falls onto the weighing pan 5 and is blocked by the electric opening and closing plate 6. The weighing pan 5 weighs the fallen intermediate. At this time, the intermediate is still in a dry environment. When the fallen intermediate reaches the required weight, the drive motor 15 is started and drives the rotating perforated disk 14 to rotate through the synchronous belt assembly. Rotation 14 causes the holes in the fixed perforated disk 13 to be out of alignment, stopping the discharge of intermediates from the storage tank 2 into the cylinder 4. At this point, the discharged intermediates are separated from the remaining intermediates, allowing the electric control valve 8 to open. When the electric control valve 8 stops, it blocks the discharge pipe 7. Then, the electric opening and closing plate 6 rotates 90 degrees to open, and when the electric opening and closing plate 6 stops, it blocks the intermediates in the weighing pan 5. The intermediates on the weighing pan 5 fall downwards into the discharge pipe 7, which discharges and collects them. Due to the action of the fixed perforated disk 13 and the rotating perforated disk 14, the discharged intermediates are separated from the remaining intermediates, preventing moisture from entering the storage tank 2 and causing the remaining intermediates to become damp, thus improving the storage effect of the intermediates. When all the intermediates in the weighing pan 5 have been discharged...Start the air supply pump 9 to discharge nitrogen into the three-way pipe 10. The nitrogen in the three-way pipe 10 is discharged into the lower inner part of the cylinder 4 and the collecting hopper 11. The flow of nitrogen dries the inner part of the cylinder 4 and the lower inner part of the collecting hopper 11. After the inner part of the cylinder 4 and the lower inner part of the collecting hopper 11 is dry, turn off the air supply pump 9, and stop discharging nitrogen into the inner part of the cylinder 4 and the lower inner part of the collecting hopper 11. Then, start the electric opening and closing plate 6 to rotate 90 degrees in the opposite direction to reset and close the discharge end of the weighing pan 5. Finally, start the electric control valve 8 to close it.

[0036] Please see Figure 8 As shown, the drying and storage equipment for fluorocephalosporin pharmaceutical intermediates also includes an agitation assembly installed on the storage tank 2. The agitation assembly includes a rotating frame 17, a heating rod 171, and a drive assembly. Two rotating frames 17 are rotatably connected to the upper front side of the storage tank 2. Heating rods 171 are symmetrically fixed to the rear side of the upper and lower rotating frames 17. When the heating rods 171 rotate, they can further dry the intermediate. A drive assembly is provided between the rotating frames 17 and the storage tank 2. When the drive assembly operates, it can drive the rotating frames 17 to rotate. The drive assembly includes a worm gear 172, a dual-shaft motor 173, and a worm 174. Worm gears 172 are fixedly mounted on the front side of the upper and lower rotating frames 17. A dual-shaft motor 173 is installed on the upper front side of the storage tank 2. Worm 174 is fixedly connected to the output shaft ends of the upper and lower sides of the dual-shaft motor 173. The upper and lower worm 174 mesh with the upper and lower worm gears 172, respectively.

[0037] Please see Figure 9 and Figure 10 As shown, the drying and storage equipment for fluorocephalosporin pharmaceutical intermediates also includes a sealing assembly installed between the cylinder 4 and the fixed perforated disk 13. The sealing assembly includes air bladders 18, a fixing frame 181, a cylinder 182, a cylinder body 183, a piston rod 184, a gas guide pipe 185, and a connecting pipe 186. Five air bladders 18 are embedded and fixedly fixed at even intervals along the circumference on the top of the fixed perforated disk 13. When the air bladders 18 inflate, they can seal the holes of the rotating perforated disk 14. The bottoms of the five air bladders 18 are connected... A gas guide pipe 185 is connected, and the gas guide pipe 185 is fixedly connected through the fixed perforated plate 13. A fixed frame 181 is fixedly connected to the upper part of the left side inside the cylinder 4. A cylinder 183 is fixedly connected to the right side inside the fixed frame 181. A piston rod 184 is slidably connected to the inside of the cylinder 183. A connecting pipe 186 is connected to the middle of the right side of the cylinder 183. The tail end of the connecting pipe 186 is fixedly connected to the middle of the gas guide pipe 185. A cylinder 182 is fixedly connected to the left side inside the fixed frame 181. The end of the telescopic rod of the cylinder 182 is fixedly connected to the left end of the piston rod 184.

[0038] When the dried intermediate is stored in storage tank 2, it is in contact with heating rod 171. For extended storage, heating rod 171 is activated first, followed by dual-shaft motor 173. Motor 173 drives the upper and lower worm gears 174 to rotate, which in turn drives the worm wheel 172. The worm wheel 172 then drives the rotating frame 17, which in turn drives the heating rod 171. The rotation of heating rod 171 agitates the intermediate in storage tank 2 and simultaneously heats and dries it. Once the intermediate has been dried for the appropriate time, heating rod 171 is turned off, and dual-shaft motor 173 is also turned off. Motor 173 stops driving worm gear 174, which in turn stops driving worm wheel 172. The worm wheel 172 then stops driving the rotating frame 17, which in turn stops the heating rod 171. This prevents water droplets from forming inside storage tank 2 in windy conditions, ensuring the intermediate remains dry.

[0039] When the intermediate material on the weighing pan 5 reaches the required amount, the drive motor 15 is activated, causing the rotating perforated disc 14 to rotate and disconnect from the fixed perforated disc 13. Then, the cylinder 182 is activated, and the extension rod of the cylinder 182 extends, causing the piston rod 184 to move to the right. The piston rod 184 pushes the air in the cylinder 183 into the connecting pipe 186, and the air in the connecting pipe 186 is discharged into the air guide pipe 185. The air in the air guide pipe 185 is discharged into the air bladder 18, which continuously expands to seal the holes of the rotating perforated disc 14. At this point, the intermediate material in the storage tank 2 will not enter the rotating perforated disc 14 and disconnect from the fixed perforated disc 13. When the cylinder 182 is closed in the gap between the fixed perforated discs 13, the piston rod 184 stops moving to the right, and the air bladder 18 stops inflating. When it is necessary to discharge the intermediate material in the storage tank 2 into the cylinder 4, the cylinder 182 is activated first. The extension rod of the cylinder 182 shortens, causing the piston rod 184 to move to the left and reset. The piston rod 184 moves to the left and reset, drawing the air in the air bladder 18 back into the cylinder 183 through the connecting pipe 186 and the air guide pipe 185. As the air is drawn away, the air bladder 18 continuously contracts and stops sealing the holes of the rotating perforated disc 14, thus allowing the rotating perforated disc 14 to rotate and connect with the fixed perforated disc 13. In this way, the intermediate material is prevented from entering the gap between the rotating perforated disc 14 and the fixed perforated disc 13 and affecting the rotation of the rotating perforated disc 14, thereby ensuring the smooth rotation of the rotating perforated disc 14.

[0040] Please see Figure 11 As shown, the drying and storage equipment for fluorocephalosporin pharmaceutical intermediates also includes a corrugated hood 19. The corrugated hood 19 is connected between the discharge end of the hopper 11 and the inlet end of the discharge pipe 7. The corrugated hood 19 can block the floating intermediates.

[0041] When the intermediate material in the weighing pan 5 is discharged, it passes through the corrugated cover 19 and is discharged into the discharge pipe 7. The corrugated cover 19 guides the intermediate material discharged from the weighing pan 5. In this way, the intermediate material in the weighing pan 5 can be accurately discharged and collected into the discharge pipe 7.

[0042] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made to the present invention without departing from the principles and spirit of the invention as defined by the claims.
