Description

Technical Field

[0001] This utility model relates to the field of plastic bottle injectable drug technology, and in particular to a closed-loop purification device for a precision filtration section of plastic bottle injectable drug. Background Technology

[0002] Plastic-bottled injectable solutions are sterile liquid medications administered via injection. The core carrier is a plastic bottle (commonly made of pharmaceutical-grade plastics such as polypropylene and polyethylene). They are widely used in clinical treatments, such as for antibiotics, nutrient solutions, and electrolyte supplements. Compared to glass-bottled injectable solutions, plastic-bottled containers are lightweight, impact-resistant, and less prone to breakage, making them more suitable for transportation and clinical use.

[0003] When performing precision filtration of injectable drugs in plastic bottles, a closed-loop system is used. The drug flows through a closed pipeline and container from entering the device, through filtration, to leaving the device and entering the next process. Purification devices are often used in the precision filtration section of injectable drugs in plastic bottles to maintain the air cleanliness of the filtration area in accordance with GMP standards, based on the environmental requirements of the drug filtration section.

[0004] In daily work, it has been found that existing air purification devices accumulate a large amount of dust on their dust filters during long-term air purification. This requires manual cleaning at regular intervals. The dust filters need to be removed and wiped, and then reassembled after cleaning. The overall operation is cumbersome, increases the workload, and causes inconvenience in cleaning. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, when purifying air for a long time, a large amount of dust will be absorbed on the dustproof screen inside, which requires manual cleaning at regular intervals. The dustproof screen needs to be removed and wiped after cleaning, and then reassembled after cleaning. The overall operation is cumbersome and increases the workload. Therefore, a closed-loop purification device for the precision filtration section of plastic bottle injectable medicine is proposed.

Detailed Implementation

[0018] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a closed-loop purification device for precision filtration of injectable liquid in plastic bottles, including a body 1. Multiple sets of filter sections 4 are detachably installed on the inner wall of the body 1 from bottom to top. The multiple sets of filter sections 4 are, from bottom to top, a nylon mesh layer, a HEPA layer and an activated carbon layer, used to purify air. An exhaust fan 2 is installed on the surface of the body 1. The input end of the exhaust fan 2 is connected to the inner wall of the body 1, and the output end is fixedly connected to an exhaust pipe 3. A cleaning device 5 is provided on the inner wall of the body 1. The cleaning device 5 includes a guide cover 51 fixed in the inner wall of the body 1. A collection tube 52 is fixedly connected to the lower surface of the guide cover 51. A collection box 53 is inserted into the inner wall of the collection tube 52. A suction part is provided between the inner wall of the body 1 and the collection tube 52 to guide impurities into the collection box 53. A shielding part is also provided between the inner wall of the body 1 and the collection tube 52 to shield and close the collection tube 52. A protective cover 58 is fixedly connected to the surface of the guide cover 51. A motor 57 is fixedly connected to the inner wall of the protective cover 58. The output end of the motor 57 passes through the guide cover 51 and the protective cover 58 and is fixedly connected to a cleaning part for cleaning the bottom dustproof filter part 4.

[0019] In this implementation scheme: When purifying the air, the exhaust fan 2 draws in the air, which enters the body 1 and passes through multiple sets of filter sections 4 for filtration. The purified air is then discharged through the exhaust pipe 56. During cleaning, the motor 57 is turned on, which drives the cleaning section to rotate and clean the bottom dustproof filter section 4. At the same time, the suction section can guide the cleaned dust into the guide cover 51 and the collection pipe 52, and finally collect it in the collection box 53. After cleaning, the shielding section shields the collection pipe 52.

[0020] Preferably, the suction unit includes a suction pump 54 fixed in the inner wall of the body 1. The output end and input end of the suction pump 54 are respectively fixedly connected to a suction tube 55 and an exhaust pipe 56. One end of the suction tube 55 is connected to the inner wall of the collection tube 52. A filter screen 59 is fixedly connected to one side of the inner wall of the collection box 53. The filter screen 59 corresponds to the suction tube 55.

[0021] In this implementation plan: During the cleaning process, the suction pump 54 is turned on. The suction pump 54 can suck up the cleaned dust through the suction pipe 55 and introduce it into the collection box 53. The dust is then intercepted by the filter screen 59 and collected in the collection box 53.

[0022] Preferably, the shielding part includes two cylinders 511 fixed in the inner wall of the body 1, and the output end of the cylinders 511 is fixedly connected to a shielding plate 510, which is slidably connected to the inner wall of the collecting pipe 52.

[0023] In this implementation scheme: when the two cylinders 511 drive the baffles 510 to move, when the two baffles 510 are in contact with each other, they can block the collection pipe 52. After the two baffles 510 are separated, the collection operation can be performed.

[0024] Preferably, the cleaning part includes a shaft 514 fixed on the output end of the motor 57, a connector 515 inserted into the inner wall of the shaft 514, a cleaning part 516 fixedly connected to the upper end of the connector 515, a screw 517 threadedly connected to the inner wall of the shaft 514, the screw 517 being inserted into the inner wall of the connector 515, and the bristles of the cleaning part 516 being made of nylon.

[0025] In this implementation scheme: the connector 515 is inserted into the shaft 514, and then the screw 517 is connected to the shaft 514. The screw 517 can be inserted into the inner wall of the connector 515 to realize the installation operation, which facilitates the subsequent replacement of the cleaning part 516.

[0027] In this implementation scheme: after the collection box 53 is inserted into the collection tube 52, the pin 512 can be inserted into the inner wall of the collection box 53. The spring 513 can drive the pin 512 to reset, while ensuring the stability of the pin 512 inserted into the inner wall of the collection box 53, thereby fixing the collection box 53.

[0028] Working principle: When the exhaust fan 2 is started, it creates negative pressure inside the body 1. After the outside air is drawn into the body 1, it passes through multiple sets of detachable filter sections 4 in sequence. Impurities in the air are intercepted by the filter sections 4. The purified air is discharged through the exhaust pipe 3 at the output end of the exhaust fan 2, achieving precise purification of the air in the work area. During cleaning, firstly, the two cylinders 511 drive the baffles 510 respectively, causing the two baffles 510 to separate and lose their blocking effect. At this time, the motor 57 and the suction air pump 54 are turned on. The output end of the motor 57 can drive the shaft 514, the connecting part 515 and the cleaning part 516 to rotate in sequence. The nylon bristles can filter the dust below. Dust adhering to the surface of part 4 is brushed off. The suction pump 54 draws air into the collection tube 52 through the suction pipe 55, creating a negative pressure inside the guide cover 51 and the collection tube 52. The cleaned dust is sucked into the collection tube 52 through the guide cover 51 and finally enters the collection box 53. The filter screen 59 inside the collection box 53 intercepts the dust, realizing the centralized collection of impurities. After cleaning, the two cylinders 511 drive the baffle plate 510 to move towards the middle and fit together, sealing the collection tube 52. When removing impurities, simply pull the pin 512, the spring 513 retracts, the pin 512 loses its restraint on the collection box 53, and the collection box 53 can be removed for dust removal.
