Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical wastewater treatment technology, and more specifically, to a pharmaceutical wastewater treatment device. Background Technology

[0002] With the rapid development of the pharmaceutical industry, the pollution control of pharmaceutical wastewater has become increasingly severe. Pharmaceutical wastewater is one of the most difficult types of industrial wastewater to treat. Due to differences in drug types and production processes, it is characterized by significant variations in composition, complex components, large amounts of pollutants, high COD, numerous recalcitrant substances, and strong toxicity. Furthermore, pharmaceutical wastewater is typically discharged intermittently, with significant variations in the types and quantities of products, leading to substantial variations in wastewater quality, quantity, and pollutant types, posing considerable challenges to treatment. Traditional wastewater treatment processes are no longer sufficient to meet the current requirements for pharmaceutical wastewater treatment. Because pharmaceutical wastewater contains solid impurities that can affect subsequent purification treatment, filtration devices are necessary for preliminary filtration before it enters the reaction chamber.

[0003] A search revealed that Chinese utility model patent application number CN202323260529.0 discloses a pharmaceutical wastewater treatment device, including a filter box, a filter cylinder inside the filter box with multiple filter holes, a cavity between the filter cylinder and the filter box, multiple arc-shaped scrapers rotatably mounted inside the filter cylinder to scrape off dirt from the surface of the filter cylinder, a collection component for collecting dirt on one side of the multiple arc-shaped scrapers, and a drive component for driving the multiple arc-shaped scrapers to rotate inside the filter cylinder on the rear side of the filter box.

[0004] During use, the curved scraper removes impurities from the surface of the filter cartridge to the bottom, preventing them from clogging the filter holes. The dust collection groove at the bottom of the curved scraper collects the impurities. While this method effectively cleans the inside of the filter cartridge to prevent clogging, when there are many impurities, tools are needed to manually clean them piece by piece. This process is time-consuming and laborious, impacting the efficiency of treating pharmaceutical wastewater. Furthermore, smaller impurities can get stuck inside the filter holes. While the curved scraper can remove these smaller impurities, it is not effective at cleaning the inside of the filter holes. Impurities stuck inside the filter holes can also cause clogging.

[0009] The present invention is further configured such that an air jet pipe is fixedly connected to the top of the inside of the filter box, a plurality of air jet nozzles are evenly connected to the bottom of the air jet pipe, and an air vent pipe is connected to the top of the air jet pipe. The top of the air vent pipe extends to the upper side of the filter box, which facilitates blowing impurities inside the filter holes of the filter cylinder into the inside of the filter cylinder, and avoids small impurities from clogging the filter holes of the filter cylinder and causing blockage.

[0010] The present invention is further configured such that multiple arc-shaped scrapers are connected to the outside of the first rotating shaft through multiple connecting plates, which facilitates the scraping away of impurities inside the filter cylinder and avoids clogging of the filter cylinder.

[0011] The present invention is further configured such that a first motor is installed on the side end of the filter box, and a second rotating shaft is fixedly connected to the output end of the first motor.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a pharmaceutical wastewater treatment device, which has the following beneficial effects:

[0018] 1. When it is necessary to clean the impurities inside the filter cartridge, multiple electric cylinders push the sealing cover to move, causing the sealing cover to separate from the filter box. The sealing cover drives the first rotating shaft and the circular scraper to move, and the circular scraper pushes out all the impurities inside the filter cartridge. This avoids the need for people to use tools to clean the impurities inside the filter cartridge bit by bit, making it easier to clean the impurities inside the filter cartridge quickly, shortening the time for cleaning the impurities inside the filter cartridge, and improving the efficiency of pharmaceutical wastewater treatment.

[0019] 2. The second motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the filter cylinder to rotate. Impurities inside the filter holes on the filter cylinder will fall out of the filter holes due to gravity, preventing impurities from clogging the filter cylinder.

[0020] 3. The air is connected to an external air blowing device through a vent pipe. The external air blowing device delivers pressurized air into the jet pipe and multiple jet nozzles. The pressurized air is evenly sprayed onto the filter cartridge through the multiple jet nozzles. As the filter cartridge rotates, it blows the impurities inside the filter holes on the top of the filter cartridge into the interior of the filter cartridge, preventing impurities from getting stuck inside the filter holes and causing the filter cartridge to become clogged.

[0030] Please see Figures 1-5A pharmaceutical wastewater treatment device includes a filter box 1 and a filter cylinder 2. The bottom of the filter box 1 is connected to a drain pipe 3, and a valve 24 is installed on the drain pipe 3 to control its opening and closing. The filter cylinder 2 is located inside the filter box 1 and is rotatably connected to it. A drive mechanism for rotating the filter cylinder 2 is installed on the filter box 1. A rotating ring 4 is rotatably connected to the side end of the filter cylinder 2. A sealing cover 5, which is sealed to the rotating ring 4 and the filter box 1, is provided on the side end of the filter box 1. A first sealing seal is fixedly connected to the side end of the sealing cover 5 at a position corresponding to that of the filter box 1. Gasket 22 ensures the sealing between the sealing cover 5 and the filter box 1. The side end of the sealing cover 5 and the corresponding position of the rotating ring 4 are fixedly connected with the second sealing gasket 23 to ensure the sealing between the sealing cover 5 and the rotating ring 4. Multiple electric cylinders 6 are installed on the filter box 1. The telescopic rods of the multiple electric cylinders 6 are fixedly connected to the sealing cover 5. The side end of the sealing cover 5 is rotatably connected to the first rotating shaft 7. The outer side of the first rotating shaft 7 away from the sealing cover 5 is fixedly connected to the round scraper 8 that cooperates with the filter cylinder 2. The sealing cover 5 is connected to the water inlet pipe 9 that communicates with the inside of the filter cylinder 2.

[0031] Specifically, when it is necessary to clean the impurities inside the filter cylinder 2, multiple electric cylinders 6 push the sealing cover 5 to move, causing the sealing cover 5 to separate from the filter box 1. The sealing cover 5 drives the first rotating shaft 7 and the circular scraper 8 to move, and the circular scraper 8 pushes out all the impurities inside the filter cylinder 2. This avoids the need for people to use tools to clean out the impurities inside the filter cylinder 2 bit by bit, making it easier to clean the impurities inside the filter cylinder 2 quickly, shortening the time for cleaning the impurities inside the filter cylinder 2, and improving the efficiency of pharmaceutical wastewater treatment.

[0032] Please see Figure 2 The top of the filter box 1 is fixedly connected to an air jet pipe 10. Multiple air jet nozzles 11 are evenly connected to the bottom of the air jet pipe 10. The top of the air jet pipe 10 is connected to an air vent pipe 12. The top of the air vent pipe 12 extends to the upper side of the filter box 1, so as to blow the impurities inside the filter holes of the filter cylinder 2 into the interior of the filter cylinder 2.

[0033] Specifically, the air pipe 12 is connected to an external air blowing device. The external air blowing device delivers pressurized air into the air jet pipe 10 and multiple air jet nozzles 11. The pressurized air is evenly sprayed onto the filter cylinder 2 through the multiple air jet nozzles 11. As the filter cylinder 2 rotates, impurities inside the filter holes on the upper part of the filter cylinder 2 are blown into the interior of the filter cylinder 2, preventing impurities from getting stuck inside the filter holes of the filter cylinder 2 and causing the filter cylinder 2 to become clogged.

[0034] Please see Figures 2-4Multiple arc-shaped scrapers 14 are connected to the outside of the first rotating shaft 7 via multiple connecting plates 13 to scrape away impurities inside the filter cylinder 2, preventing the filter cylinder 2 from clogging. A first motor 15 is installed on the side of the filter box 1. A second rotating shaft 16 is fixedly connected to the output end of the first motor 15. The second rotating shaft 16 is rotatably connected to the filter box 1 and the filter cylinder 2 in a sealed manner. A regular hexagonal column 17 is fixedly connected to the side of the second rotating shaft 16. A regular hexagonal groove 18 is provided on the side of the first rotating shaft 7. The regular hexagonal column 17 is inserted into the interior of the regular hexagonal groove 18.

[0035] Specifically, the cooperation between the regular hexagonal column 17 and the regular hexagonal groove 18 facilitates the connection between the first rotating shaft 7 and the rotating shaft, and at the same time facilitates the separation between the second rotating shaft 16 and the first rotating shaft 7. The first motor 15 drives the second rotating shaft 16, the regular hexagonal column 17, the first rotating shaft 7, the multiple connecting plates 13 and the multiple arc-shaped scrapers 14 to rotate. The arc-shaped scrapers 14 scrape away the impurities inside the filter cylinder 2, preventing the filter cylinder 2 from becoming clogged.

[0036] Please see Figure 1 , Figure 3 and Figure 5 The drive mechanism includes a second motor 19 and a gear ring 20. The second motor 19 is installed on the side of the filter box 1, and the gear ring 20 is fixedly installed on the outside of the filter cylinder 2. A gear 21 is fixedly connected to one end of the output shaft of the second motor 19 that extends into the inside of the filter box 1. The gear 21 meshes with the gear ring 20. The output shaft of the second motor 19 is sealed and rotatably connected to the filter box 1, which facilitates driving the filter cylinder 2 to rotate.

[0037] Specifically, the second motor 19 drives the gear 21 to rotate, the gear 21 drives the gear ring 20 to rotate, and the gear ring 20 drives the filter cylinder 2 to rotate. Impurities inside the filter holes on the filter cylinder 2 will fall out of the filter holes due to gravity, thus preventing impurities from clogging the filter cylinder 2.

[0038] In summary, when using the overall equipment:

[0039] Pharmaceutical wastewater is transported to the interior of filter cylinder 2 through inlet pipe 9. The wastewater is filtered through filter cylinder 2 and flows through the filter holes of filter cylinder 2 to the bottom of the interior of filter box 1, and is discharged through drain pipe 3. At the same time, the second motor 19 drives gear 21 to rotate, gear 21 drives gear ring 20 to rotate, gear ring 20 drives filter cylinder 2 to rotate. The first motor 15 drives the second rotating shaft 16, regular hexagonal column 17, first rotating shaft 7, multiple connecting plates 13 and multiple arc scrapers 14 to rotate. The arc scrapers 14 scrape away the impurities inside filter cylinder 2. At the same time, the external air blowing device delivers air with a certain pressure into the air jet pipe 10 and multiple air jet nozzles 11. The air with a certain pressure is evenly sprayed onto filter cylinder 2 through multiple air jet nozzles 11. During the rotation of filter cylinder 2, the impurities inside the filter holes on the upper part of filter cylinder 2 are blown out.

[0040] When it is necessary to clean the impurities inside the filter cartridge 2, multiple electric cylinders 6 push the sealing cover 5 to move, so that the sealing cover 5 is separated from the filter box 1. The sealing cover 5 drives the first rotating shaft 7 and the circular scraper 8 to move, and the circular scraper 8 pushes out all the impurities inside the filter cartridge 2.
