Description

Technical Field

[0001] The invention relates to the field of pharmaceutical processing equipment, in particular to a medicine dispensing filtering device. Background Art

[0002] In the fields of pharmaceutical production and scientific research, the filtration of drug liquid is a crucial link. Traditional drug liquid filtration methods often have many problems and cannot meet the needs of the modern pharmaceutical industry for efficient and accurate filtration.

[0003] On the one hand, in the process of liquid medicine filtration, how to ensure that the liquid medicine and the filter aid are fully mixed has always been a difficult problem. If the mixing is not sufficient, the filter aid cannot effectively absorb the tiny particles, colloids and other impurities in the liquid medicine, resulting in poor filtration effect. Traditional stirring methods may not achieve sufficient mixing, or the mixing efficiency is low, affecting production progress and product quality.

[0004] On the other hand, it is also difficult to control the ratio of liquid medicine and filter aids. Different liquid medicines may require different ratios of filter aids to achieve the best filtration effect. However, it is difficult for traditional filtration devices to accurately control the amount of filter aids and liquid medicine, resulting in unstable ratios and affecting the consistency of filtration effects.

[0005] In addition, traditional filtering devices may have unreasonable structural designs, such as unstable transmission structures and loose fit between components, which lead to low operating reliability of the device and prone to failure, increasing maintenance costs and production risks.

[0006] In summary, in order to solve the problems of insufficient mixing, difficult ratio control and unreasonable structural design existing in the traditional liquid medicine filtration method, it is particularly necessary to develop a new type of drug dispensing and filtering device. The present invention aims to provide a drug dispensing and filtering device that can achieve sufficient mixing of liquid medicine and filter aid, accurately control the ratio and has a stable and reliable structure.

[0017] Working principle: First, add the liquid medicine to be filtered into the liquid medicine feeding storage box, add the liquid medicine filter aid into the filter aid storage box, the filter aid will enter the feeding barrel through the filter aid feeding pipe, and the liquid medicine will enter the liquid medicine feeding pipe through the liquid feeding pipe, then start the reduction motor, drive the stirring rod to rotate through the reduction motor, drive the lower bevel gear to rotate, the rotating lower bevel gear meshes with the transmission bevel gear, drive the transmission bevel gear and the light rod to rotate, the rotation of the light rod will drive the driving wheel to rotate, and then drive the driven wheel and the rotating rod through the transmission of the synchronous belt, the rotating rotating rod will drive the second cam and sleeve When the sleeve rotates, the limiting effect of the spline and the keyway will drive the first shaft to rotate. Since the first shaft and the second shaft are connected to the transmission shaft through a universal joint, when the first shaft rotates, the movement transmission effect of the transmission shaft will drive the second shaft to rotate, thereby driving the first cam to rotate. When the first cam rotates, it will drive one end of the first connecting rod to follow the movement, and the other end of the first connecting rod will drive the feed barrel to move up and down along the direction of the filter aid discharge pipe. When the feed barrel descends, part of the leakage holes on both sides of the feed barrel will move to the inside of the filter chamber, and the inside of the feed barrel will The filter aid enters the filter cartridge in the filter chamber through the leakage hole to realize the quantitative addition of the filter aid. When the second cam rotates, it will drive one end of the second connecting rod to follow the movement, and the other end of the second connecting rod will drive the blocking block, the push-pull rod and the blocking plug to move up and down along the direction of the liquid medicine discharge pipe. When they descend, the blocking block will open the bottom of the liquid discharge channel, so that the liquid medicine in the liquid medicine discharge pipe flows into the filter cartridge of the filter chamber. At the same time, when the blocking plug descends, it will block the connection between the liquid medicine discharge pipe and the liquid medicine discharge pipe to prevent it from entering the interior, thereby realizing the quantitative addition of liquid medicine. When both the liquid medicine and the filter aid are added When the liquid medicine enters the filter cartridge, the rotating stirring rod drives the stirring blades on both sides to move, thereby mixing the two. At the same time, when the lower bevel gear drives the transmission bevel gear to rotate, it will also drive the upper bevel gear to rotate in the opposite direction. The rotating upper bevel gear will drive the transmission rod and the filter cartridge to rotate. The forward rotating stirring blades and the reverse rotating filter cartridge are used to achieve full mixing of the liquid medicine and the filter aid, and to adsorb impurities such as tiny particles and colloids in the liquid medicine, thereby improving the material passing effect. When the filter cartridge rotates, centrifugal force is also generated to throw the liquid medicine out of the filter cartridge, thereby filtering the liquid medicine, and the filtered liquid medicine is discharged through the drain pipe.

[0018] When it is necessary to adjust the ratio of filter aid and liquid medicine, the threaded rod is driven to rotate by rotating the first adjusting knob, and the limiting effect of the guide rod is used to drive the limiting seat and the second rotating shaft to move up and down. When the second rotating shaft is displaced, the initial position of the feed barrel in the filter aid discharge pipe is changed, thereby controlling the height of the leakage hole of the feed barrel entering the filter chamber each time. When the height changes, the leakage amount will also change accordingly, thereby realizing the adjustment of the discharge amount of filter aid each time. Subsequently, the second adjusting knob is rotated, and the second adjusting knob will drive the internal thread on the inner ring to rotate and mesh with the external thread of the movable ring seat. The limiting effect of the limiting rod is used to drive the movable ring seat to move up and down in the liquid medicine discharge pipe. When the position of the movable ring seat changes, the storage space in the liquid medicine discharge pipe will also change, thereby realizing the adjustment of the discharge amount of liquid medicine each time. By adjusting the discharge amount of filter aid and the liquid medicine, it can be ensured that the two are always in the best ratio state, thereby improving the later filtering effect.

[0019] The present invention provides a medicine dispensing filtering device, which has the following beneficial effects: 1. The present invention fully mixes the drug liquid with the filter aid through the forward rotating stirring blade and the reverse rotating filter cartridge, which can effectively adsorb impurities such as tiny particles and colloids in the drug liquid, greatly improving the filtering effect. The centrifugal force generated by the rotation of the filter cartridge is used to throw the drug liquid out of the filter cartridge to achieve efficient filtration of the drug liquid.

[0020] 2. After starting the reduction motor, the present invention uses a series of transmission structures to make the feed barrel move up and down along the filter aid discharge pipe. When the feed barrel descends, part of the leakage holes on both sides thereof move to the inside of the filter chamber, thereby quantitatively adding the filter aid into the filter barrel, and the second cam rotates to drive the blocking block, the push-pull rod and the stopper to move up and down. When they descend, the blocking block opens the bottom of the liquid discharge channel to allow the liquid medicine to flow into the filter barrel, and at the same time the stopper blocks the connection between the liquid discharge pipe and the liquid medicine discharge pipe, thereby realizing quantitative addition of the liquid medicine.

[0021] 3. The present invention drives the threaded rod to rotate by rotating the first adjusting knob, so that the limit seat and the second rotating shaft move up and down, and the initial position of the feed barrel in the filter aid discharge pipe is changed, so as to control the height of the leakage hole and adjust the discharge amount of the filter aid each time. By rotating the second adjusting knob, the movable ring seat is driven to move up and down in the liquid medicine discharge pipe through the meshing transmission of the internal thread and the external thread of the movable ring seat, and the storage space of the liquid medicine discharge pipe is changed to realize the adjustment of the liquid medicine discharge amount each time, thereby ensuring that the filter aid and the liquid medicine are always in the best ratio state, and further improving the later filtering effect.

The space inside the filter chamber 1 is used to accommodate the medicinal liquid and the filter aid. The centrifugal force is generated by rotation to throw out the filtered medicinal liquid. A transmission rod 4 is fixedly connected to the middle part of the bottom end of the filter cartridge 3. The transmission rod 4 is responsible for transmitting power to the filter cartridge 3 so that it can achieve reverse rotation.

When the device is running, the stirring rod 7 and the stirring blades 8 stir and mix the liquid medicine and the filter aid in the filter cartridge 3 so that the two are in full contact, thereby improving the filtering effect.

[0027] A polished rod 10 is movably mounted on one side of the bottom of the filter chamber 1 through a bearing seat, and the polished rod 10 plays a transmission role in the device. A filter aid discharge pipe 12 is fixedly mounted on one side of the top of the filter chamber 1, and a filter aid storage box 13 is fixedly connected to the top of the filter aid discharge pipe 12. The filter aid storage box 13 is used to store liquid filter aid, and the filter aid enters the interior of the device through the filter aid discharge pipe 12.

[0028] A liquid medicine discharge pipe 14 is fixedly installed on the other side of the top of the filter chamber 1 , and a liquid medicine storage box 15 is fixedly connected above the liquid medicine discharge pipe 14 . The liquid medicine storage box 15 stores the liquid medicine to be filtered, and the liquid medicine enters the filter chamber 1 through the liquid medicine discharge pipe 14 .

[0029] A sleeve 16 is movably mounted on one side of the top wall of the filter chamber 1 through a bearing seat, and the sleeve 16 plays an important role in the transmission system of the device. A rotating rod 30 is movably mounted on the other side of the top wall of the filter chamber 1 through a bearing seat.

[0030] In this embodiment, the bottom end of the transmission rod 4 passes through the bottom wall of the filter chamber 1 and is fixedly connected to the upper bevel gear 5, the lower bevel gear 9 is fixedly installed on the lower outer diameter of the stirring rod 7, and the inner end of the light rod 10 is fixedly installed with a transmission bevel gear 11, and the upper and lower sides of the transmission bevel gear 11 are respectively meshed and connected with one side of the upper bevel gear 5 and the lower bevel gear 9. When the device is running, the reduction motor 6 drives the stirring rod 7 to rotate, driving the lower bevel gear 9 to rotate, and the lower bevel gear 9 is meshed and transmitted with the transmission bevel gear 11, thereby driving the transmission bevel gear 11 to rotate, and the transmission bevel gear 11 is meshed with the upper bevel gear 5, driving the upper bevel gear 5 to rotate in the opposite direction, and the upper bevel gear 5 drives the filter cartridge 3 to rotate in the opposite direction through the transmission rod 4, thereby realizing the reverse motion with the stirring blade 8, thereby improving the mixing effect of the liquid medicine and the filter aid.

[0031] Specifically, when the medicine liquid and the filter aid are added into the filter cartridge 3, the rotating stirring rod 7 drives the stirring blades 8 on both sides to move, thereby achieving mixing of the two. At the same time, when the lower bevel gear 9 drives the transmission bevel gear 11 to rotate, it will also drive the upper bevel gear 5 to rotate in the opposite direction. The rotating upper bevel gear 5 will drive the transmission rod 4 and the filter cartridge 3 to rotate. By utilizing the forward rotating stirring blades 8 and the reverse rotating filter cartridge 3, the medicine liquid and the filter aid are fully mixed, and impurities such as tiny particles and colloids in the medicine liquid are adsorbed to improve the filtering effect. When the filter cartridge 3 rotates, centrifugal force is also generated to throw the medicine liquid out of the filter cartridge 3, thereby achieving filtering of the medicine liquid.

When the sleeve 16 rotates, the first rotating shaft 17 is driven to rotate through the cooperation of the keyways 18 and the splines 19, thereby ensuring stable transmission of power.

[0033] Furthermore, a transmission shaft 20 is movably mounted on one end of the first rotating shaft 17 close to the filter aid storage box 13 through a universal joint, a second rotating shaft 21 is movably mounted on the end of the transmission shaft 20 through a universal joint, a first cam 22 is fixedly mounted on the end of the second rotating shaft 21, a feed barrel 23 is movably arranged inside the filter aid storage box 13, leakage holes 24 are provided on both sides of the feed barrel 23, a first connecting rod 25 is movably mounted on the bottom end of the feed barrel 23, and the end of the first connecting rod 25 is movably mounted on the end of the first cam 22. When the first rotating shaft 17 rotates Through the movement transmission action of the transmission shaft 20, the second rotating shaft 21 is driven to rotate, thereby causing the first cam 22 to rotate. When the first cam 22 rotates, it drives one end of the first connecting rod 25 to follow the movement, and the other end of the first connecting rod 25 drives the feed barrel 23 to move up and down along the direction of the filter aid discharge pipe 12. When the feed barrel 23 descends, part of the leakage holes 24 on both sides thereof move into the filter chamber 1, and the filter aid inside the feed barrel 23 enters the filter barrel 3 in the filter chamber 1 through the leakage holes 24, thereby realizing the work of quantitatively adding the filter aid.

[0034] Furthermore, the outer diameter of the second rotating shaft 21 is movably set in the middle of the limit seat 26, and one side of the inner part of the limit seat 26 is connected to the top wall of the filter chamber 1 through the guide rod 27, and the other side of the inner part of the limit seat 26 is threadedly connected to the outer diameter of the threaded rod 28. The top end of the threaded rod 28 extends to the outside of the filter chamber 1 and is fixedly connected with a first adjusting knob 29. The threaded rod 28 is driven to rotate by rotating the first adjusting knob 29, and the limit seat 26 and the second rotating shaft 21 are moved up and down by utilizing the limiting effect of the guide rod 27. When the second rotating shaft 21 is displaced, the initial position of the feed barrel 23 in the filter aid discharge pipe 12 will be changed, thereby controlling the height of the leakage hole 24 in the filter chamber 1 each time the feed barrel 23 enters. When the height changes, the leakage amount will also change accordingly, thereby realizing the adjustment of the discharge amount of the filter aid each time.

[0035] Furthermore, a driving wheel 31 is fixedly installed on the outer end of the light rod 10, and the outer end of the rotating rod 30 extends to the outside of the filter chamber 1 and is fixedly installed with a driven wheel 32. The outer diameters of the driving wheel 31 and the driven wheel 32 are connected by a synchronous belt 33. When the light rod 10 rotates, the driving wheel 31 will be driven to rotate, and then the driven wheel 32 and the rotating rod 30 will be driven to rotate through the transmission of the synchronous belt 33.

[0036] Furthermore, both sides of the bottom end of the medicine liquid storage box 15 are fixedly connected with a down-liquid pipe 37 and the ends of the down-liquid pipe 37 extend to the inside of the medicine liquid discharge pipe 14, and a movable ring seat 38 is movably installed inside the medicine liquid discharge pipe 14, and a down-liquid channel 39 is opened in the middle of the movable ring seat 38, and a fixed ring seat 40 is fixedly connected to the lower side of the inside of the medicine liquid discharge pipe 14, and both sides of the top end of the fixed ring seat 40 are fixedly connected with a limiting rod 41 and the ends of the limiting rod 41 extend to the inside of the movable ring seat 38, and the medicine enters the medicine liquid discharge pipe 14 through the down-liquid pipe 37, and the movable ring seat 38, the fixed ring seat 40 and the limiting rod 41 work together to provide a structural basis for the quantitative addition of the medicine liquid.

[0037] Furthermore, the inner ends of the sleeve 16 and the rotating rod 30 are connected through the second cam 34, the middle part of the second cam 34 is movably mounted with a second connecting rod 35, the inner top of the liquid medicine discharge pipe 14 is movably mounted with a stopper 36, the middle part of the bottom end of the stopper 36 is fixedly connected with a push-pull rod 48, the end of the push-pull rod 48 passes through the interior of the liquid discharge channel 39 and is fixedly connected with a blocking block 42, the end of the second connecting rod 35 is movably mounted on the bottom end of the blocking block 42, when the rotating rod 30 rotates, the second cam 34 is driven to rotate, and the second cam 34 When rotating, one end of the second connecting rod 35 is driven to move along, and the other end of the second connecting rod 35 drives the blocking block 42, the push-pull rod 48 and the plug 36 to move up and down along the direction of the liquid medicine discharge pipe 14. When they descend, the blocking block 42 will open the bottom of the liquid discharge channel 39, so that the liquid medicine in the liquid medicine discharge pipe 14 flows into the filter cartridge 3 of the filter chamber 1. At the same time, when the plug 36 descends, it will block the connection between the liquid medicine discharge pipe 37 and the liquid medicine discharge pipe 14 to prevent the liquid medicine from continuing to enter, thereby realizing the work of quantitatively adding the liquid medicine.

[0038] Specifically, the liquid medicine to be filtered is added into the liquid medicine feeding storage box, and the liquid medicine filter aid is added into the filter aid storage box. The filter aid will enter the feeding barrel 23 through the filter aid feeding pipe 12, and the liquid medicine will enter the liquid medicine feeding pipe 14 through the liquid lower pipe 37. Then, the reduction motor 6 is started, and the stirring rod 7 is driven to rotate by the reduction motor 6, which drives the lower bevel gear 9 to rotate. The rotating lower bevel gear 9 is meshed with the transmission bevel gear 11 to drive the transmission bevel gear 11 and the polished rod 10 to rotate. When the polished rod 10 rotates, it will bring The driving wheel 31 rotates, and then the driven wheel 32 and the rotating rod 30 are driven to rotate through the transmission of the synchronous belt 33. The rotating rotating rod 30 drives the second cam 34 and the sleeve 16 to rotate. When the sleeve 16 rotates, the first rotating shaft 17 is driven to rotate by the limiting effect of the spline 19 and the keyway 18. Since the first rotating shaft 17 and the second rotating shaft 21 are connected to the transmission shaft 20 through a universal joint, when the first rotating shaft 17 rotates, the motion transmission effect of the transmission shaft 20 is used to drive the second rotating shaft 21 to rotate, thereby driving The first cam 22 also rotates. When the first cam 22 rotates, it drives one end of the first connecting rod 25 to follow the movement, and the other end of the first connecting rod 25 drives the feed barrel 23 to move up and down along the direction of the filter aid discharge pipe 12. When the feed barrel 23 descends, part of the leakage holes 24 on both sides of the feed barrel 23 will move into the filter chamber 1, and the filter aid inside the feed barrel 23 will enter the filter barrel 3 in the filter chamber 1 through the leakage holes 24, so as to achieve the work of quantitatively adding the filter aid. When the second cam 34 rotates When the plug 36 descends, it will drive one end of the second connecting rod 35 to move along, and the other end of the second connecting rod 35 will drive the blocking block 42, the push-pull rod 48 and the plug 36 to move up and down along the direction of the liquid medicine discharge pipe 14. When they descend, the blocking block 42 will open the bottom of the liquid discharge channel 39, so that the liquid medicine in the liquid medicine discharge pipe 14 flows into the filter cartridge 3 of the filter chamber 1. At the same time, when the plug 36 descends, it will block the connection between the liquid medicine discharge pipe 37 and the liquid medicine discharge pipe 14 to prevent it from entering the interior, thereby realizing the work of quantitative addition of liquid medicine.

[0039] Furthermore, a second adjusting knob 43 is movably mounted on the outer diameter of the liquid medicine discharge pipe 14, and an internal thread 44 is provided at the inner end of the second adjusting knob 43.

A discharge pipe 46 is fixedly connected to one side of the bottom end of the filter chamber 1, and support legs 47 are fixedly connected to the four corners of the bottom end of the filter chamber 1. By rotating the second adjusting knob 43, the internal thread 44 on the inner ring is driven to rotate and mesh with the external thread 45 of the movable ring seat 38. The movable ring seat 38 is driven to move up and down in the liquid medicine discharge pipe 14 by utilizing the limiting effect of the limiting rod 41. When the position of the movable ring seat 38 changes, the storage space in the liquid medicine discharge pipe 14 will also change, thereby realizing the adjustment of the liquid medicine discharge amount each time. The discharge pipe 46 is used to discharge the filtered liquid, and the support legs 47 provide stable support for the entire device.

[0040] Specifically, when it is necessary to adjust the ratio of the filter aid and the liquid medicine, the threaded rod 28 is driven to rotate by rotating the first adjusting knob, and the limiting effect of the guide rod 27 is utilized to drive the limiting seat 26 and the second rotating shaft 21 to move up and down. When the second rotating shaft 21 is displaced, the initial position of the feed barrel 23 in the filter aid discharge pipe 12 is changed, thereby controlling the height of the leakage hole 24 in the filter chamber 1 each time the feed barrel 23 enters. When the height changes, the leakage amount will also change accordingly, thereby realizing the adjustment of the discharge amount of the filter aid each time, and then rotating the second adjusting knob 4 3. The second adjusting knob 43 drives the internal thread 44 on the inner ring to rotate and meshes with the external thread 45 of the movable ring seat 38. The limiting function of the limiting rod 41 drives the movable ring seat 38 to move up and down in the liquid medicine discharge pipe 14. When the position of the movable ring seat 38 changes, the storage space in the liquid medicine discharge pipe 14 will also change, thereby realizing the adjustment of the liquid medicine discharge amount each time. By adjusting the filter aid discharge amount and the liquid medicine discharge amount, it can be ensured that the two are always in the best ratio state, thereby improving the later filtering effect.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
