Description

Technical Field

[0001] The invention relates to the technical field of liquid medicine recovery and treatment, in particular to liquid medicine recovery and treatment equipment with a filter element cleaning function. Background Art

[0002] In the pharmaceutical industry, due to the wide variety of drugs and complex production processes, the waste liquid components are extremely complex and diverse. They include unreacted raw materials, reaction by-products, organic solvents, heavy metal ions, and various biologically active substances. These substances are not only in high concentrations, but many of them are highly toxic and bio-inhibitory, posing a serious threat to the ecological environment and human health. For example, the residual antibiotic components in some antibiotic pharmaceutical waste liquids may cause the generation and spread of microbial resistance after entering the environment; and the discharge of waste liquid containing heavy metal ions into water bodies or soil will cause long-term environmental pollution and affect the ecological balance.

[0003] A Chinese patent with authorization announcement number CN205088052U discloses a pharmaceutical waste liquid recovery and recycling device, a primary recovery device and a secondary recovery device, wherein the interior of the primary recovery device is divided into a dissolving chamber and an air flotation chamber by a horizontally arranged first partition, a waste liquid inlet is provided on one side of the dissolving chamber, and the waste liquid inlet is connected to an opening at the bottom of the air flotation chamber through a conduit, and by arranging the dissolving chamber and the air flotation chamber in the primary recovery device, the larger particles in the pharmaceutical waste liquid are separated into a slag discharge port by utilizing the air flotation principle, thereby improving the separation efficiency of the medicinal residue in the waste liquid, and then by arranging a water collecting bin in the secondary recovery device and arranging a through hole on the partition at the bottom of the water collecting bin, the waste liquid is evenly spread on the filter net, effectively filtering and recovering the smaller particles of the medicinal residue, thereby improving the speed of waste liquid separation and recovery.

[0004] In the existing drug waste liquid recovery and treatment device, the filter element is easily clogged during the filtration process due to the different sizes and high content of impurity particles in the drug waste liquid. As the filtration time increases, a large amount of drug residue will gradually accumulate on the surface of the filter element, resulting in a smaller filtration aperture and a sharp drop in the filtration speed. In order to maintain the normal operation of the device, the filter element has to be replaced frequently. This not only increases the purchase cost of the filter element, but also causes the device to shut down due to the replacement of the filter element, reduces the overall processing efficiency, and affects the production continuity of the enterprise; most traditional devices lack effective automatic cleaning functions for the filter element and often rely on manual cleaning. Manual cleaning of the filter element requires the filter element to be removed from the device first, and then cleaned one by one. This process is extremely cumbersome and time-consuming. During the cleaning process, since the drug waste liquid may be corrosive and toxic, the operator is easily exposed to harmful substances, which poses a great safety risk. In addition, manual cleaning is difficult to ensure the consistency and thoroughness of the cleaning effect, and in the process of removing and installing the filter element, it is easy to cause waste liquid leakage, further polluting the environment and causing environmental problems.

The outer wall of the recovery tank 100 is also provided with a three-way plate 130 for support. The recovery tank 100 stands on a plane through the three-way plate 130, and the medicine is introduced into the inlet pipe 110. The medicine intermittently and slowly enters the inner cavity of the recovery tank 100 through the inlet pipe 110. The three-way pipe 121 located at the top of the recovery tank 100 is used to discharge the medicine, and the clean water pipe 122 is used to pour clean water into the recovery tank 100.

[0050] The rotating unit 530 includes a driving motor 532 and a disc gear 531 . The disc gear 531 is fixed to the end of the output shaft of the driving motor 532 . The driving motor 532 drives the disc gear 531 to rotate.

[0051] like Figure 4 As shown, the combination rod 441 includes an upper rod 4411 and an intermediate upper rod 4412 , a group of ring gears 44121 are fixed to the surface of the intermediate upper rod 4412 , and the rotating unit 530 is engaged with the ring gears 44121 to drive the intermediate upper rod 4412 to rotate.

The extension plate 4422 has a cavity 4423 inside, and the cavity 4423 of the extension plate 4422 is connected to the double-headed nozzle 4425 .

[0072] Exemplarily, the flushing pipe 600 is configured as a hose, and the flushing pipe 600 is fixed to the inner wall of the middle upper rod 4412 .

[0073] Exemplarily, the fine sieve slots of the fine sieve plate 431, the coarse sieve slots of the coarse sieve plate 421, the guide port 412 of the deflector 411 and the double-headed nozzle 4425 are all arranged in a one-to-one correspondence, and when the double-headed nozzle 4425 moves upward, the through hole 4331 passing through the surface of the fine sieve filter mesh plate 433 abuts against the fine sieve cover plate 4321, and when the double-headed nozzle 4425 moves downward, it abuts against the coarse sieve cover plate 4221, so that the coarse sieve cover plate 4221 covers the coarse sieve filter mesh plate 4223 to block the coarse sieve slots.

[0074] like Figure 3 As shown, the end of the recovery tank 100 away from the three-way assembly 120 is connected to the introduction pipe 110, and the end of the introduction pipe 110 that passes through the recovery tank 100 is connected to the diversion assembly 300. The diversion assembly 300 includes an integrated main through pipe 310 and a multi-component diversion pipe 320. The multi-component diversion pipe 320 is connected to the main through pipe 310, and an opening is provided at the end of the diversion pipe 320 away from the main through pipe 310; an annular baffle 150 is fixed at the bottom end of the inner wall of the recovery tank 100.

[0075] Exemplarily, the liquid medicine enters the diversion pipe 320 through the main through pipe 310 and then flows into the range of the annular baffle 150. Large impurity particles move on the inner wall of the recovery tank 100 under the action of gravity and fluid. The moving large impurity particles are blocked by the annular baffle 150, and small particles are suspended in the water flow and are screened by the coarse screen filter element 420 and the fine screen filter element 430.

[0076] A group of sensing diaphragms 140 are fixed on the inner surface of the recovery tank 100 , and a group of miniature infrared cameras are installed on the top of the middle upper rod 4412 . The sensing diaphragms 140 are used to receive infrared rays emitted by the miniature infrared cameras and sense the position of the middle upper rod 4412 .

[0077] Exemplarily, a controller is provided inside the driving motor 532 , and the controller is used to reset the output end of the driving motor 532 , and control the output end of the driving motor 532 to drive the disc gear 531 to rotate a certain angle.

[0078] Exemplarily, a controller is provided inside the linear motor, and the controller is used to receive the signal emitted by the induction diaphragm 140 and adjust and control the position of the middle upper rod 4412 .

[0079] Exemplarily, a water level line is provided in the fine screen cavity, and a water pump is installed in the inlet pipe 110, and the water pump is used to pump the medicine liquid into the recovery tank 100 through the inlet pipe 110 until the medicine liquid reaches the water level line.

[0080] Working principle: The liquid medicine enters the diversion assembly 300 through the inlet pipe 110, and flows into the range of the annular baffle 150 after being diverted by the main pipe 310 and the diversion pipe 320. Large impurity particles move on the inner wall of the recovery tank 100 under the action of gravity and fluid and are blocked by the annular baffle 150, while small particles are suspended in the water flow waiting to be filtered.

[0081] As the medicine is introduced, the liquid level of the medicine gradually increases, and the medicine enters the coarse screen cavity from the guide port 412 of the baffle plate 411 and then stops at the water level line in the fine screen cavity. The multiple coarse screen grooves on the surface of the coarse screen plate 421 allow the medicine to pass through, and the coarse screen filter plate 4223 installed in the coarse screen grooves serves to intercept larger particles of impurities.

[0082] At this time, the linear motor acts on the stretching plate 520 through the extended straight rod, so that the stretching plate 520 moves linearly. The stretching plate 520 is fixed to the surface wall of the upper ejector rod 4411, thereby driving the upper ejector rod 4411 to move up and down along the axis direction of the recovery tank 100. The movement of the upper ejector rod 4411 synchronously drives the middle upper rod 4412 to move up and down, thereby making the middle lower rod 4413 and the lower bottom rod 4414 connected to the middle upper rod 4412 also move up and down. The lower bottom rod 4414 presses on the coarse screen filter element 420 to make the coarse screen filter element 420 move toward the deflector assembly 410, realizing the downward pressing action of the coarse screen plate 421, and the medicinal liquid enters the fine screen cavity. The coarse screen filter mesh plate 4223 continuously To filter the medicinal liquid, the second sealing plate 423 abuts against the guide port 412 of the deflector plate 411 to seal the guide port 412; when the coarse screen filter element 420 abuts against the surface of the deflector assembly 410 and moves downward again, the I-shaped rod 44131 and the spring 44132 are forced to shrink, and the bending insert plate 44133 is driven toward the card plate 44141 until it is located in the same horizontal plane as the card slot of the card plate 44141, and at this time, the middle upper rod 4412 also synchronously moves into the meshing range of the disc gear 531, and the disc gear 531 meshes with the ring gear 44121, and the driving motor 532 drives the disc gear 531 to rotate, so that the middle upper rod 4412 rotates with the axis of the upper rod 4411 as the center line. The rotation of the middle upper rod 4412 drives the middle lower rod 4413 to rotate, and the rotating middle lower rod 4413 drives the bending insert plate 44133 to rotate and insert into the slot of the bending insert plate 44133, thereby achieving the locking of the clamping plate 44141 and the bending insert plate 44133.

[0083] The linear motor acts on the upper push rod 4411 by extending the straight rod to make the upper push rod 4411 move upward, and the moved upper push rod 4411 drives the middle upper rod 4412 so that the middle upper rod 4412 drives the middle lower rod 4413 to move upward. Since the bending insert plate 44133 and the clamping plate 44141 are locked, the lower bottom rod 4414 will move up synchronously with the middle lower rod 4413, and simultaneously drive the coarse screen filter element 420 to move away from the deflector assembly 410, and the coarse screen filter element 420 drives the medicine between the coarse screen plate 421 and the fine screen plate 431 to enter through the fine screen plate 431 and enter the upper cavity, and the water pressure squeezes the fine screen cover plate 4321 to move away from the fine screen plate 431 to open the fine screen slot.

[0084] As the coarse screen filter element 420 continues to move upward, the action frame 442 also moves upward, and the double-headed nozzle 4425 passes through the through hole 4331 and abuts against the fine screen cover plate 4321, and a large amount of water flows from the fine screen groove into the upper cavity.

[0085] When the coarse screen filter element 420 moves up to the water level line, the water pump starts working again, the inlet pipe 110 introduces the medicine into the recovery tank 100, and the linear motor moves down through the combination rod 441 to drive the middle upper rod 4412 to move synchronously to the meshing range of the disc gear 531, and the driving motor 532 drives the disc gear 531 to rotate to engage with the ring gear 44121 to drive the combination rod 441 to rotate and reset, and the linear motor continues to drive the coarse screen filter element 420 to reset through the combination rod 441.

[0086] Exemplarily, pressure relief devices are provided in both the fine screen cavity and the coarse screen cavity to prevent the coarse screen filter element 420 from being unable to move due to the pressure.

[0087] Illustratively, the double-ended nozzle 4425 always moves above the coarse screen plate 421 during the rotation process.

[0088] Each time the coarse screen filter element 420 and the fine screen filter element 430 screen the liquid medicine, they will be cleaned by the cleaning liquid. Specifically, when the coarse screen filter element 420 moves up to the water level line, the water pump starts to work again, at this time, the lower part of the double-headed nozzle 4425 passes through the circular hole of the coarse screen plate 421 and faces the coarse screen filter screen plate 4223, the upper part of the double-headed nozzle 4425 passes through the fine screen filter screen plate 433 and faces the fine screen cover plate 4321, the clean water sprayed by the lower part of the double-headed nozzle 4425 passes through the circular hole of the coarse screen plate 421 and faces the coarse screen filter screen plate 4223 to wash, the clean water sprayed by the upper part of the double-headed nozzle 4425 is deflected by the fine screen cover plate 4321 and then cleans the fine screen filter screen plate 433, completing the cleaning of the coarse screen filter screen plate 4223 and the fine screen filter screen plate 433.

[0089] The device diverts the liquid medicine through the diversion component 300, uses the annular baffle 150 to block large impurity particles, and the coarse screen filter element 420 and the fine screen filter element 430 intercept and filter small particle impurities in turn, which can effectively remove various impurities in the liquid medicine and ensure the purity and quality of the recovered liquid medicine. At the same time, the components are flexibly linked and controlled: the linear drive unit 510 and the rotation unit 530 work together, so that the combination rod 441 can accurately control the movement and state switching of the coarse screen filter element 420 and the fine screen filter element 430, thereby realizing the orderly flow of the liquid medicine between different chambers and the efficient switching of the filtration process.

[0090] During the operation of the equipment, when the liquid medicine enters the diversion assembly 300 through the inlet pipe 110 and enters the area sealed by the annular baffle plate 150 after diversion, large impurity particles are blocked, and small particles are suspended in the water flow and are ready to enter the coarse screen cavity. At this time, the coarse screen grooves on the surface of the coarse screen plate 421 of the coarse screen filter element 420 and the assembled coarse screen filter screen plate 4223 begin to play a role. The liquid medicine must pass through the coarse screen filter screen plate 4223 to enter the coarse screen cavity. This process realizes the preliminary filtration of the liquid medicine, intercepts larger particles of impurities, and ensures that the liquid medicine entering the coarse screen cavity is purified to a certain extent.

[0091] As the filtering process progresses, the components cooperate closely and move in coordination. The linear drive unit 510 drives the combination rod 441 to move linearly, driving the coarse screen filter element 420 and related components connected to the combination rod 441 to move up and down, and realizing actions such as the coarse screen plate 421 pressing down to block the guide port 412 and subsequent position resetting; while the rotation unit 530, by engaging with the combination rod 441, causes the combination rod 441 to produce a rotational motion, thereby driving the rotation of the middle lower rod 4413 and other components, completing actions such as locking and unlocking the bending insert 44133 and the card plate 44141, accurately controlling the opening and closing and movement of the coarse screen filter element 420 and the fine screen filter element 430, realizing the orderly transfer and precise filtration of the drug liquid between the coarse screen cavity, the fine screen cavity and the upper cavity, avoiding the situation where the drug liquid enters the subsequent chamber without being fully filtered, greatly improving the automation and operation stability of the equipment, reducing the complexity of manual operation and the error risk caused by human factors, and improving the overall production efficiency and equipment reliability.

[0092] After each filtering cycle, the coarse screen filter plate 4223 and the fine screen filter plate 433 are fully cleaned by using the double-headed nozzle 4425 connected by the clean water pipe 122 and the flushing pipe 600, which has significant advantages. During the operation of the equipment, the nozzle 44426 of the double-headed nozzle 4425 is precisely aligned with the surface of the coarse screen filter plate 4223 and the fine screen filter plate 433 as the coarse screen filter element 420 moves. The precise alignment design greatly improves the cleaning effect. Since the distance and angle between the nozzle 44426 and the coarse screen filter plate 4223 and the fine screen filter plate 433 can be maintained in the optimal state, the clean water for cleaning can be concentrated and efficiently act on the coarse screen filter plate 4223 and the fine screen filter plate 433, which can not only effectively remove impurities attached to the surface of the coarse screen filter plate 4223 and the fine screen filter plate 433, but also significantly reduce the amount of clean water required for cleaning compared to the traditional non-precision cleaning method. While ensuring thorough cleaning, the cleaning efficiency is improved, thereby reducing cleaning time and water consumption. By removing impurities in a timely manner, the good filtering performance of the coarse screen filter element 420 and the fine screen filter element 430 is maintained, the service life of the coarse screen filter element 420 and the fine screen filter element 430 is effectively extended, and the high cost and downtime caused by frequent replacement of the coarse screen filter element 420 and the fine screen filter element 430 are reduced, ensuring that the equipment always maintains a high filtering efficiency and stability during long-term use, providing a solid guarantee for the continuity and stability of the production process.
