Description

Technical Field

[0001] The invention relates to the technical field of drug processing, in particular to mixed liquid filtering equipment for ciprofloxacin lactate drug processing. Background Art

[0002] Ciprofloxacin lactate is usually prepared from ciprofloxacin hydrochloride through neutralization and salt-forming reactions. Unreacted raw materials, by-products and other impurities may be generated during the reaction process. Other impurities, such as metal ions and activated carbon particles, may also be introduced during the subsequent preparation of the mixed solution. Filtration is an important means to remove these impurities, which helps to improve product quality and yield and ensure drug quality.

[0003] In the traditional filtration process of ciprofloxacin lactate drug processing, filter bags are usually used to perform preliminary filtration of the mixed liquid. However, a large amount of impurities usually remain in the drug mixture. These impurities can be effectively removed after filtration, but the filtered impurities will be adsorbed inside the filter bag or cause clogging of the filter bag holes, then the filtering effect of the filter bag will be reduced. In order to avoid the clogging of the filter bag affecting the filtration quality, the filter bag needs to be replaced or cleaned. During this process, the machine will stop running, which will directly affect the filtration processing efficiency of the device for the drug mixture. Summary of the Invention

[0007] Replace the components to make the filter bags rotate in a circular rectangle. After the filter bags move to the clean area, the filter bags at the rear end alternately move to the bottom of the guide plate, thus realizing the alternating replacement of the filter bags and avoiding the blockage caused by long-term use of the filter bags.

DETAILED DESCRIPTION

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0033] Reference Figures 1-8 As shown, the present invention provides a technical solution: a mixed liquid filtering device for processing ciprofloxacin lactate drugs, comprising a filter tank 1, a housing 2 fixedly connected to one side of the filter tank 1, a guide plate 3 fixedly connected to the interior of the filter tank 1, a funnel tube 4 fixedly connected to the bottom of the filter tank 1, a filter bag 5 provided at the bottom of the guide plate 3, and long rods 6 fixedly connected to the bottom of the filter bag 5 on all sides. The mixed liquid filtering device for processing ciprofloxacin lactate drugs also includes a spray pipe 7 and a rubber plate 8;

[0034] A cleaning assembly is provided on the top of the filter bag 5, so that the filter bag 5 drives the long rod 6 to turn counterclockwise 180 degrees during the replacement process, so that the blockage inside the filter bag 5 is poured downward, and then the long rod 6 falls down under its own gravity to turn the inside of the filter bag 5 outward, and the spray pipe 7 moves downward into the inside of the filter bag 5, and water is sprayed from the inside of the filter bag 5 to clean the filter bag 5, ensuring that the inside of the filter bag 5 is not blocked by impurities that affect the filtering effect;

[0035] Replace the components so that the filter bag 5 rotates in a circular rectangular shape. After the filter bag 5 moves to the clean area, the filter bag 5 at the rear end alternates to the bottom of the guide plate 3, thereby realizing the alternate replacement of the filter bag 5 and avoiding the blockage of the filter bag 5 due to long-term use.

[0036] The auxiliary mechanism is connected to the cleaning component in a transmission manner to drive the rubber plate 8 to rotate during the lifting and lowering of the spray pipe 7, so that the rubber plate 8 rotates to slap the surface of the filter bag 5, shake off the impurities adsorbed on the surface of the filter bag 5, and avoid stubborn impurities from being adsorbed on the surface of the filter bag 5. The filter bag 5 is driven to move for replacement and use by the replacement component. At the same time, the replaced filter bag 5 enters the cleaning area for cleaning. After pouring out the dirt inside the filter bag 5, the use surface is turned over to rinse the filter bag 5 from the inside out. The filter bag 5 is then slapped by the auxiliary mechanism to increase the falling speed of the dirt adsorbed by the filter bag 5, so that the filter bag 5 can be cyclically used and cleaned, avoiding the accumulation of excessive impurities in the filter bag 5 due to long-term operation, which affects the filtration quality of the drug mixture.

[0037] Reference Figures 1-8 As shown, in this embodiment: the cleaning component includes:

[0038] Extension plate 9, a toothed belt 10 is installed on the top of the extension plate 9, four moving rods 11 are fixedly connected to the surface of the toothed belt 10, and the surface of the moving rod 11 is rotatably connected to a rotating plate 12. One side of the rotating plate 12 is fixedly connected to a circular frame plate 13, and the bottom of the circular frame plate 13 is fixedly connected to four extension rods 14. The surface of the extension rod 14 is slidably connected to a sleeve plate 15. The interior of the sleeve plate 15 is slidably connected to the surface of the long rod 6. One side of the extension plate 9 is fixedly connected to two toothed plates 16. The two toothed plates 16 are respectively placed on the top and bottom of the rotating plate 12. The top of the shell 2 is fixedly connected to a motor 17, and a worm 18 is installed on one side of the motor 17. A lifting plate 19 is installed on the surface of the worm 18. One side of the lifting plate 19 is fixedly connected to the top of the spray pipe 7. The spray pipe There are two channels 7. A spray device 20 is installed on the top of the shell 2. The spray device 20 is connected to the spray pipe 7 through a water supply pipe. A drain pipe 24 is installed at the bottom of the shell 2. The top of the drain pipe 24 is connected to the inside of the shell 2. The bottom height of the inner wall of the shell 2 is slightly lower than the height of the connection with the filter tank 1. The ciprofloxacin acid drug mixture is transported into the filter tank 1 through the pipeline on the surface of the filter tank 1. The mixed liquid is guided to the inside of the filter bag 5 through the guide plate 3, so that the mixed liquid is filtered by the filter bag 5 and then drips to the top of the funnel pipe 4. The funnel pipe 4 then transports the filtered mixed liquid to the next step. When the filter bag 5 absorbs certain impurities after long-term use, the staff controls the computer to start the replacement component operation, so that the filter bag 5 in use is transported to the left When the filter bag 5 follows the replacement assembly and moves to the bottom of the tooth plate 16, the tooth plate 16 will engage with the surface of the rotating plate 12. When the filter bag 5 continues to move to the left, the tooth plate 16 will push the rotating plate 12 to rotate counterclockwise, so that the rotating plate 12 and the circular frame plate 13 rotate 180 degrees, and the bottom of the filter bag 5 is rotated to the top. In this process, the extension rod 14 will also rotate with the circular frame plate 13. In the process of flipping the filter bag 5, the extension rod 14 and the long rod 6 will gradually tilt. Due to the influence of the gravity of the sleeve plate 15 and the long rod 6, the long rod 6 will slide downward along the inner wall of the sleeve plate 15, and the sleeve plate 15 will also slide downward along the extension rod 14. This makes the filter bag 5 flip 180 degrees, and the opening of the filter bag 5 is in a downward state. At this time, the inside of the filter bag 5 is The impurities can be poured out downwards, and the downward movement of the long rod 6 and the sleeve plate 15 will cause the sleeve plate 15 to slide to the other end of the extension rod 14 due to the binding and fixation of the long rod 6 and the rope at the bottom of the filter bag 5, and the long rod 6 will slide along the sleeve plate 15 into the interior of the filter bag 5. Through this process, the top outer side of the flipped filter bag 5 is inserted into the opening of the filter bag 5, so that the top of the filter bag 5 is pushed downward by the long rod 6 through the opening of the filter bag 5 and moves to the bottom position of the filter bag 5, which makes the filter bag 5 turn over from the inside to the outside after flipping, and then the replacement component stops running. At this time, the filter bag 5 will be directly below the spray pipe 7, and the motor 17 will drive the worm 18 to operate to make the lifting plate 19 descend, and the spray pipe 7 is moved downward through the lifting plate 19 to insert into the interior of the filter bag 5.Afterwards, the spray pipe 7 and the spray device 20 are put into operation. The spray pipe 7 is placed inside the filter bag 5 to flush the inner surface of the filter bag 5 from the inside out. Then, the drain pipe 24 is placed at the bottom of the cleaning area to guide and discharge the clean sewage generated inside the shell 2. At the same time, since the bottom height of the inner wall of the shell 2 is lower than the height of one side of the filter tank 1, there is a certain height between one side of the filter tank 1 and the shell 2, which prevents the moisture inside the shell 2 from penetrating into the interior of the filter tank 1, thereby preventing the sewage from polluting the mixed liquid. At the same time, the drain pipe 24 can be connected to the sewage filtering equipment to prevent the residual drug impurities in the wastewater generated by the cleaning of the filter bag 5 from affecting the water resource environment.

[0039] Finally, the filter bag 5 will follow the operation of the replacement assembly and move to the bottom of the guide plate 3 for filtering use;

[0040] When the filter bag 5 enters the cleaning area, it is first turned counterclockwise to dump out the internal impurities, and then the long rod 6 falls, driving the bottom area of ​​the filter bag 5 to move, turning the inside and outside of the filter bag 5, and finally the spray pipe 7 moves to the inside of the filter bag 5 for flushing, so that the impurities adsorbed and accumulated inside the filter bag 5 can be dumped out when the filter bag 5 is used for a long time. After turning it over, flushing from the inside to the outside is more conducive to the discharge of dirt inside the filter bag 5, and avoiding the dirt from entering the filtering area of ​​the filter bag 5 during further flushing, so as to achieve the purpose of cleaning the filter bag 5, facilitate the filter bag 5 to perform efficient filtration, and avoid the filter bag 5 being blocked after long-term use without being cleaned or replaced, thereby affecting the production efficiency of the device.

[0041] Reference Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, in this embodiment: the replacement components include:

[0042] Two gears 21, the bottom of the gear 21 is fixedly connected to a motor 22, the bottom of the motor 22 is fixedly connected to the extension plate 9, the inner diameter of the toothed belt 10 is meshed with the surface of the gear 21, and a one-way door plate 23 is installed on both sides of the inside of the filter tank 1. The bottom of the guide plate 3 is fixedly connected to a guide shell 31, and one side of the guide shell 31 is fixedly connected to an inclined plate 32. The surface of the circular frame plate 13 is slidably connected to the inner wall of the guide shell 31. The bottom of the guide plate 3 is fixedly connected to an arc plate 33. There are two arc plates 33, and the two arc plates 33 are divided into two inner and outer ones. The arc plates 33 are placed on both sides of the bottom opening of the guide plate 3. The gear 21 is driven to rotate by the motor 22, and the gears are rotated by the gears. The meshing connection between the wheel 21 and the toothed belt 10 causes the gear 21 to drive the toothed belt 10 to rotate clockwise. During the process, the moving rod 11 will follow the rotation position of the toothed belt 10 to move the position of the filter bag 5, which makes the filter bag 5 move away from the bottom of the guide plate 3 when the toothed belt 10 rotates. The filter bag 5 moves close to the one-way door plate 23 to squeeze the middle of the one-way door plate 23, so that the one-way door plate 23 is opened. After the filter bag 5 moves past, the one-way door plate 23 will not be pushed and will rebound to its original position, closing the space between the shell 2 and the filter tank 1, preventing water from splashing into the filter tank 1 when the spray pipe 7 flushes the filter bag 5 and contaminating the mixed liquid. After that, the filter bag 5 on the right moves to the bottom of the guide plate 3 and The one-way door panel 23 will be squeezed to open and close, and the filter bag 5 in use will be moved to the cleaning area for cleaning to complete the replacement of the filter bag 5. During this process, the filter bag 5 does not need to be removed, and the filter tank 1 only needs to stop running for a short time to complete the replacement of the filter bag 5. When the toothed belt 10 drives the circular frame plate 13 to move counterclockwise, one side of the circular frame plate 13 will gradually approach the inclined plate 32, so that the surface of the circular frame plate 13 is guided along the inclination of the inclined plate 32 and gradually enters the inside of the guide shell 31. After that, the circular frame plate 13 and the filter bag 5 are moved to the bottom of the guide plate 3 for use, which makes one side of the circular frame plate 13 supported by the guide shell 31. When the mixed liquid flows into the filter bag 5, the filter The connection between the mechanism at the top of the bag 5 and the toothed belt 10 will not bend and deform due to the weight of the filter bag 5, thereby ensuring the stability of the filter bag 5 in the use area and avoiding its displacement to cause gaps that affect the filtering effect. A curved plate 33 is provided at the bottom of the guide plate 3, so that the curved plates 33 are distributed on both sides of the opening at the bottom of the guide plate 3. The spacing formed by the two curved plates 33 is adapted to the size of the top inlet of the filter bag 5, so that when the filter bag 5 is placed at the bottom of the guide plate 3, the curved plate 33 can better guide the mixed liquid into the interior of the filter bag 5 for filtration, and avoid the mixed liquid from seeping to the outside of the filter bag 5 when the mixed liquid flows downward from the guide plate 3, affecting the filtering effect of the filter bag 5 on the mixed liquid.

[0043] Reference Figure 5 and Figure 8 As shown, in this embodiment: the auxiliary mechanism includes:

[0044] The shaft 25, the surface of the shaft 25 is rotatably connected to the rotating shell 26, the shaft 25 is fixedly connected to one side of the inner wall of the shell 2, the surface of the shaft 25 is rotatably connected to the rotating shell 26, the surface of the rotating shell 26 is fixedly connected to several rubber plates 8, the top of the rotating shell 26 is fixedly connected to the screw rod 27, the screw rod 27 is rotatably connected to the surface of the shaft 25, the surface of the screw rod 27 is threadedly connected to the sleeve plate 28, one end of the sleeve plate 28 is fixedly connected to the lifting plate 19, when the filter bag 5 is placed directly below the spray pipe 7, when the worm 18 drives the lifting plate 19 to move downward, the sleeve plate 28 will also move downward with the descent of the lifting plate 19, which makes the sleeve plate 28 sleeve the surface of the screw rod 27. When the spray pipe 7 moves downward, due to the threaded connection between the sleeve plate 28 and the screw rod 27, the sleeve plate 28 descends. It will drive the screw rod 27 to rotate along the shaft 25, and the screw rod 27 will also drive the rotating shell 26 and the rubber plate 8 to rotate, which makes the rubber plate 8 rotate when the spray pipe 7 descends or rises. When the spray pipe 7 descends, the filter bag 5 will be in an uncleaned state. The centrifugal force generated by the rotation of the rubber plate 8 will straighten itself and slap the surface of the filter bag 5, so that the filter bag 5 vibrates under the action of the rubber plate 8, and then the dirt adsorbed on the surface of the filter bag 5 is shaken off, further increasing the cleaning effect of the filter bag 5. When the spray pipe 7 rises, the filter bag 5 will complete cleaning. At this time, the rubber plate 8 will rotate a second time, and by slapping the surface of the filter bag 5 itself, the moisture adsorbed inside the filter bag 5 will be slapped down, reducing the moisture adsorbed inside the filter bag 5 after cleaning, which is more conducive to the drying efficiency of the filter bag 5 after cleaning.

[0045] Reference Figure 1 and Figure 8 As shown, in this embodiment: a heating device 29 is fixedly connected to the top of the shell 2, and a warm air pipe 30 is installed at the bottom of the heating device 29. The warm air pipe 30 is placed in the middle of several spray pipes 7. When the spray pipe 7 enters the interior of the filter bag 5 to complete the flushing and cleaning of the filter bag 5, the heating device 29 will be started to discharge warm air into the warm air pipe 30. The warm air is discharged into the interior of the filter bag 5 through the warm air pipe 30, and the internal environment of the filter bag 5 is heated and continuous wind blowing is generated to speed up the drying efficiency of the filter bag 5 after cleaning, thereby preventing the filter bag 5 from absorbing moisture and breeding bacteria after cleaning, affecting the filtering effect of the filter bag 5 on the mixed liquid, and allowing the filter bag 5 to be put into use faster after cleaning.

[0046] Working principle: The ciprofloxacin acid drug mixture is transported into the interior of the filter tank 1 through the pipeline on the surface of the filter tank 1. The mixed liquid is guided to the interior of the filter bag 5 through the guide plate 3, so that the mixed liquid is filtered by the filter bag 5 and drips to the top of the funnel tube 4. The funnel tube 4 then transports the filtered mixed liquid to the next step. When the filter bag 5 absorbs a certain amount of impurities after long-term use, the staff controls the computer to start the replacement component operation, so that the filter bag 5 in use is transported to the left. When the filter bag 5 moves to the bottom of the tooth plate 16 following the replacement component, the tooth plate 16 will engage with the surface of the rotating plate 12. As the filter bag 5 continues to move to the left, the tooth plate 16 will push the rotating plate 12 is rotated counterclockwise, so that the rotating plate 12 and the circular frame plate 13 rotate 180 degrees, and the bottom of the filter bag 5 is rotated to the top. In this process, the extension rod 14 will also rotate with the circular frame plate 13. In the process of the filter bag 5 turning over, the extension rod 14 and the long rod 6 will gradually tilt. Due to the influence of the gravity of the sleeve plate 15 and the long rod 6, the long rod 6 will slide downward along the inner wall of the sleeve plate 15, and the sleeve plate 15 will also slide downward along the extension rod 14. After the filter bag 5 is turned over 180 degrees, the opening of the filter bag 5 is in a downward state. At this time, the impurities inside the filter bag 5 can be poured out downward, and the downward movement of the long rod 6 and the sleeve plate 15 will be due to the long rod 6 and the filter bag 5. The binding and fixation of the bottom rope causes the sleeve 15 to slide to the other end of the extension rod 14, and the long rod 6 will slide along the sleeve 15 into the interior of the filter bag 5. Through this process, the outer side of the top of the flipped filter bag 5 is inserted into the opening of the filter bag 5, so that the top of the filter bag 5 is pushed downward by the long rod 6 through the opening of the filter bag 5 and moves to the bottom position of the filter bag 5, which makes the filter bag 5 turn over from the inside to the outside. After that, the replacement component stops running. At this time, the filter bag 5 will be directly below the spray pipe 7. At this time, the motor 17 drives the worm 18 to operate to make the lifting plate 19 descend, and the spray pipe 7 is moved downward through the lifting plate 19 to insert into the interior of the filter bag 5, and then the spray The pipe 7 and the spray device 20 operate, and the spray pipe 7 is placed inside the filter bag 5 to rinse the inner surface of the filter bag 5 from the inside to the outside. The drain pipe 24 is then placed at the bottom of the cleaning area to guide and discharge the clean sewage generated inside the shell 2. At the same time, since the bottom height of the inner wall of the shell 2 is lower than the height of one side of the filter tank 1, there is a certain height between one side of the filter tank 1 and the shell 2, which prevents the moisture inside the shell 2 from penetrating into the interior of the filter tank 1, thereby preventing the sewage from polluting the mixed liquid. At the same time, the drain pipe 24 can be connected to the sewage filtering equipment to prevent the residual drug impurities in the wastewater generated by the cleaning of the filter bag 5 from affecting the water resource environment;

[0047] Finally, the filter bag 5 will follow the operation of the replacement assembly and move to the bottom of the guide plate 3 for filtering use;

[0048] The motor 22 drives the gear 21 to rotate, and the gear 21 is engaged with the toothed belt 10, so that the gear 21 drives the toothed belt 10 to rotate clockwise. During the process, the moving rod 11 will follow the rotation position of the toothed belt 10 to move the position of the filter bag 5, so that when the toothed belt 10 rotates, the filter bag 5 will be removed from the bottom of the guide plate 3, and then the filter bag 5 on the right side will move to the bottom of the guide plate 3. The filter bag 5 in use is moved to the cleaning area for cleaning to complete the replacement of the filter bag 5. When the filter bag 5 is placed directly under the spray pipe 7, the worm 18 drives the lifting plate 19 to move downward, and the sleeve plate 28 will also move downward with the descent of the lifting plate 19, which makes the sleeve plate 28 sleeve on the surface of the screw rod 27. When the spray pipe 7 moves downward, due to the sleeve plate The threaded connection between 28 and the screw rod 27 causes the sleeve plate 28 to drive the screw rod 27 to rotate along the shaft 25 when it descends, and the screw rod 27 also drives the rotating shell 26 and the rubber plate 8 to rotate, which causes the rubber plate 8 to rotate when the spray pipe 7 descends or rises. When the spray pipe 7 descends, the filter bag 5 will be in an uncleaned state. The centrifugal force generated by the rotation of the rubber plate 8 will straighten itself and slap the surface of the filter bag 5, causing the filter bag 5 to vibrate under the action of the rubber plate 8, thereby shaking off the dirt adsorbed on the surface of the filter bag 5, further increasing the cleaning effect of the filter bag 5. When the spray pipe 7 rises, the filter bag 5 will complete cleaning. At this time, the rubber plate 8 will rotate a second time, and by slapping the surface of the filter bag 5 itself, the moisture adsorbed inside the filter bag 5 will be slapped down.
