[0002] Biopharmaceutical raw materials are mainly natural biological materials, including microorganisms, human bodies, animals, plants, marine life, etc. With the development of biotechnology, purposefully artificially produced biological raw materials have become the main source of current biopharmaceutical raw materials. In the biopharmaceutical workshop, it is necessary to control the air quality of the workshop to prevent microbial contamination and ensure the production of high-quality, high-purity biological drugs. However, some medicinal raw materials will produce a lot of dust during processing. If these dusts are not treated and then discharged, they will pollute the atmosphere. At the same time, the purpose of dust-free purification is to provide a highly clean environment to prevent microbial contamination and ensure the quality of drugs. In the biopharmaceutical production process, tiny particles, bacteria, viruses and other microorganisms may affect the purity and effectiveness of drugs.

[0003] At present, filter plates are installed in the exhaust pipes to the outside of the biopharmaceutical workshop to filter dust in the workshop air and reduce the pollution of dust to the outdoor air. However, after the filter plate is used for a long time, the dust will cause blockage to the filter plate, affecting the air discharge volume. Users need to clean it regularly. Since the air outlet pipe is usually set at a high place, it is very difficult and troublesome for users to clean the filter plate. Therefore, an improved dust-free purification device for biopharmaceuticals is urgently needed. Utility Model Content

[0026] See also Figures 1 to 4 In the utility model: a dust-free purification device for biopharmaceuticals, including an air outlet pipe 1, one front end of the air outlet pipe 1 is connected to a mounting box 2, the top of the mounting box 2 is open, the inner wall of the mounting box 2 is rotatably connected to a filter cartridge 3, the back of the filter cartridge 3 is open, the front of the mounting box 2 is fixedly connected to a motor 4, the output shaft of the motor 4 is fixedly connected to the filter cartridge 3, one front end of the air outlet pipe 1 is located inside the filter cartridge 3, and the inner wall of the mounting box 2 is provided with two cleaning mechanisms 5.

[0027] In the utility model, the air with dust in the biopharmaceutical workshop will enter the installation box 2 through the air outlet pipe 1, and then the air will rise and pass through the filter cartridge 3, the filter cartridge 3 will filter the dust in the air, and the filtered air will be discharged from the top of the installation box 2, thereby achieving the effect of dust-free purification of the air in the biopharmaceutical side key. After a period of use, a large amount of dust will adhere to the top of the filter cartridge 3, affecting the air filtering effect. The user turns on the motor 4, and the motor 4 will drive the filter cartridge 3 to rotate. After the filter cartridge 3 rotates, the filter cartridge 3 with dust will move to the cleaning liquid in the installation box 2, and the cleaning liquid will clean the filter cartridge 3, thereby achieving the effect of cleaning the filter cartridge 3. The cleaned filter cartridge 3 will move to the top of the air outlet pipe 1, and at this time, the air will be discharged from the cleaned filter cartridge 3, thereby maintaining the air filtering effect in the biopharmaceutical workshop.

[0028] See also Figure 3, wherein: the cleaning mechanism 5 includes a fixed block 501, the back of the fixed block 501 is fixedly connected to the inner wall of the installation box 2, a sliding rod 502 slidably connected to the fixed block 501 is inserted, the bottom end of the sliding rod 502 is fixedly connected to a cleaning brush 503, the bottom of the cleaning brush 503 contacts the inner wall of the filter cylinder 3, and a spring 504 is sleeved on the sliding rod 502, and the two ends of the spring 504 are fixedly connected to the cleaning brush 503 and the fixed block 501 respectively.

[0029] In the utility model, the elastic force of the spring 504 can drive the cleaning brush 503 to be in close contact with the inner wall of the filter cartridge 3. As the filter cartridge 3 rotates, the cleaning brush 503 will slide along the inner wall of the filter cartridge 3, thereby achieving the effect of cleaning the filter cartridge 3, so that the cleaning liquid can enhance the cleaning effect of the filter cartridge 3 and maintain the effect of removing dust from the air.

[0030] See also Figures 1 to 4 , wherein: a cavity 6 is provided at the bottom of the installation box 2, a water pumping pipe 7 is connected to the inner wall of the cavity 6, the top of the water pumping pipe 7 is connected to the installation box 2, the top of the water pumping pipe 7 is located inside the filter cartridge 3, the inner wall of the cavity 6 is connected to a return pipe 8, the top of the return pipe 8 is connected to the installation box 2, the top of the return pipe 8 is located below the filter cartridge 3, and a water pump 9 is installed on the water pumping pipe 7; a mounting plate 12 slidably connected to the right side of the installation box 2 is inserted, a mounting groove 13 is provided on the mounting plate 12, and a filter plate 14 is fixedly connected to the inner wall of the mounting groove 13.

[0031] In the utility model, when the filter cartridge 3 is self-cleaned, the user turns on the water pump 9, the water pump 9 will draw out the cleaning liquid inside the installation box 2 and draw it into the cavity 6 through the suction pipe 7, and then the cleaning liquid will pass through the filter plate 14 on the installation plate 12, the filter plate 14 will filter the cleaning liquid, and the filtered cleaning liquid will then flow back to the installation box 2 from the reflux pipe 8 on the cavity 6, and then the cleaning liquid will pass through the filter cartridge 3 in the reverse direction and then be drawn into the suction pipe 7, thereby realizing the circulation of the cleaning liquid. During the circulation of the cleaning liquid, the cleaning liquid passes through the filter cartridge 3 in the reverse direction, which can achieve the effect of backwashing cleaning of the filter cartridge 3, further improving the cleaning effect of the filter cartridge 3, and improving the effect of air dust removal in biopharmaceuticals.

[0032] See also Figure 3 and 4 , wherein: the top end of the return pipe 8 is connected to a water outlet box 10, the shape of the water outlet box 10 is arc-shaped, and the top of the water outlet box 10 is provided with water outlet grooves 11 arranged at equal distances.

[0033] In the utility model, by using the water outlet box 10 and the water outlet tank 11 in coordination, the cleaning liquid can pass through the filter cartridge 3 evenly, thereby improving the effect of backwash cleaning of the filter cartridge 3 and improving the practicability of the device.

[0034] See also Figure 4 , wherein: two electric push rods 15 fixedly connected to the filter plate 14 are inserted thereon, and the other ends of the two electric push rods 15 are fixedly connected to sealing plates 16 adapted to the mounting groove 13 .

[0035] In the present invention, the sealing plate 16 can be driven to approach the filter plate 14 by turning on the electric push rod 15 until the sealing plate 16 moves to both sides of the filter plate 14. At this time, the sealing plate 16 will close the mounting groove 13, and the closed mounting plate 12 can be drawn out of the cavity 6. After the mounting groove 13 is pulled out of the mounting box 2, the user turns on the electric push rod 15 to move the sealing plate 16 away from the filter plate 14, so as to clean the dirt on the filter plate 14. In the process, the leakage of the cleaning liquid during the withdrawal of the mounting plate 12 can be effectively avoided, thereby improving the practicality of the device.

[0036] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
