[0025] like Figures 1-4 The diagram illustrates a wastewater recovery device for an RO reverse osmosis water purifier according to an embodiment of the present invention. The device includes: a wastewater discharge tank 1; a storage tank 6 located below the wastewater discharge tank 1; a treatment tank 4 located at one end of the wastewater discharge tank 1; and an ozone generator 7 located at the end of the treatment tank 4 furthest from the wastewater discharge tank 1. A chute 17 is provided on the treatment tank 4, and a partition 13 is slidably connected to the chute 17. A stirring rod 11 is located above the partition 13, and a filter screen 23 is located below the partition 13. Both ends of the filter screen 23 are slidably connected to... A collection net 24 is provided, and a cleaning brush 22 is provided on the filter net 23; two sets of dispensing mechanisms 9 are fixedly connected to the top of the treatment tank 4, and heavy metal supplements and alum are stored in the two sets of dispensing mechanisms 9 respectively; the wastewater discharged from the RO reverse osmosis pure water machine is collected by setting a wastewater discharge tank 1, and when the wastewater is full, it is discharged into the treatment tank 4 for sedimentation. After the heavy metals and impurities in the wastewater are replaced, the baffle 13 is removed to filter the dirt, and then ozone is delivered to the water through the ozone generator 7 to disinfect the virus in the water. The disinfection work needs to last for more than 30 minutes; A third electric motor 20 is fixedly connected to one end of the treatment tank 4 away from the sewage discharge tank 1. A reciprocating screw 21 is fixedly connected to the output end of the third electric motor 20. The other end of the reciprocating screw 21 is rotatably connected to the treatment tank 4. The reciprocating screw 21 is threadedly connected to a cleaning brush 22. The cleaning brush 22 is slidably connected to the treatment tank 4 and slidably connected to the top of the filter screen 23. The third electric motor 20 is controlled by a PLC and is fixedly connected to an external power supply. Driving the third electric motor 20 to rotate causes the reciprocating screw 21 to rotate, and the rotation of the reciprocating screw 21 causes the cleaning brush 20 to slide along the treatment tank 4. A second electric motor 15 is fixedly connected to one end of the treatment tank 4 near the sewage discharge tank 1. A threaded rod 16 is fixedly connected to the output end of the second electric motor 15. The threaded rod 16 is threadedly connected to the partition 13. A sliding rod 18 is fixedly connected to the treatment tank 4 and is slidably connected to the partition 13. The second electric motor 15 is controlled by a PLC and is fixedly connected to an external power supply. Driving the second electric motor 15 to rotate causes the threaded rod 16 to rotate. The rotation of the threaded rod 16 causes the partition 13 to slide along the slide groove 17. The sliding rod 18 helps to improve the stability of the sliding of the partition 13. The treatment tank 4 has a through groove 19 at the end away from the sewage discharge tank 1. The through groove 19 is slidably connected to the partition 13. A sealing ring is fixedly connected inside the through groove 19. A scraper 12 is fixedly connected to the treatment tank 4. The bottom end of the scraper 12 is connected to the top end of the partition 13. The partition 13 is sealed to the through groove 19. The scraper 12 is used to scrape off the sediment at the top of the partition 13. A motor 8 is fixedly connected to the top of the treatment tank 4. The output end of the motor 8 passes through the treatment tank 4 and is fixedly connected to a stirring rod 11. A limiting rod is sleeved on the outside of the stirring rod 11 and is fixedly connected to the treatment tank 4. A movable door 10 is sealed and connected to the treatment tank 4. The movable door 10 is detachable, which facilitates the disassembly of the collection net 24 for cleaning by staff. The motor 8 is controlled by a PLC and is fixedly connected to an external power source. The motor 8 drives the stirring rod 11 to rotate, which helps to improve the mixing reaction of heavy metal supplements and alum with wastewater.

[0026] For example, such as Figure 4 As shown, the second electric motor 15 is driven to rotate, which in turn drives the threaded rod 16 to rotate. The rotation of the threaded rod 16 causes the partition 13 to slide along the slide groove 17. The sliding rod 18 is provided to improve the stability of the sliding of the partition 13, so that the treated wastewater falls below the partition 13. The sediment is filtered by the filter screen 23 and the collection screen 24. The third electric motor 20 is driven to rotate, which in turn drives the reciprocating screw 21 to rotate. The rotation of the reciprocating screw 21 causes the cleaning brush 20 to slide along the treatment box 4, discharging the impurities above the filter screen 23 into the collection screen 24. This helps to prevent the filtration effect from weakening due to the clogging of the filter screen 23, reduces the number of cleaning times for workers, and maintains the normal operation of the equipment.

[0027] like Figures 1-5As shown, this invention illustrates a wastewater recovery device for an RO reverse osmosis water purifier in one embodiment. The two sets of dispensing mechanisms 9 include dispensing tanks 901, with a cover plate 902 hinged to the top of each tank. A first electric motor 903 is fixedly connected to one end of each tank. The output of the first electric motor 903 is fixedly connected to a rotating block 904, which is rotatably connected to the tank. The rotating block 904 is cross-shaped, and its outer wall is in close contact with the tank. Heavy metal supplements and alum are added through the cover plate 902. The first electric motor 903 is controlled by a PLC and fixedly connected to an external power source. The rotation of the first electric motor 903 drives the rotating block 904 to rotate, thus adding the heavy metal supplements and alum into the treatment tank 4. The output end of the ozone generator 7 is fixedly connected to the delivery pipe 3, and one end of the delivery pipe 3 passes through the treatment box 4 and is fixedly connected to the aeration head 14; by setting the aeration head 14, the contact area between ozone and water can be increased, thereby improving the disinfection efficiency. The input end of the wastewater discharge tank 1 is fixedly connected to the conveying pipe 3, which is connected to the RO reverse osmosis pure water machine body. The output end of the wastewater discharge tank 1 is fixedly connected to the conveying pipe 3, and the other end of the conveying pipe 3 is fixedly connected to the first water pump 2. The output end of the first water pump 2 is fixedly connected to the conveying pipe 3, and the conveying pipe 3 is fixedly connected to the treatment tank 4. The output end of the treatment tank 4 is fixedly connected to the conveying pipe 3, and the other end of the conveying pipe 3 is fixedly connected to the second water pump 5. The output end of the second water pump 5 is fixedly connected to the storage tank 6 through the conveying pipe 3. Both the first water pump 2 and the second water pump 5 can be controlled by a PLC. The first water pump 2 and the second water pump 5 are respectively fixedly connected to an external power supply. By driving the first water pump 2, the wastewater inside the wastewater discharge tank 1 is transported to the upper end of the partition 13 inside the treatment tank 4. The working time of the first water pump 2 is controlled to limit the volume of wastewater entering the treatment tank 4. By driving the second water pump 5, the disinfected water is input into the storage tank 6 through the conveying pipe 3 for storage, making the treated water convenient for users. For example, such as Figure 5As shown, the wastewater inside the sewage discharge tank 1 is transported to the upper end of the partition 13 in the treatment tank 4 by driving the first water pump 2. The volume of wastewater entering the treatment tank 4 is limited by controlling the working time of the first water pump 2. The rotating block 904 is rotated by driving the first electric motor 903 to rotate. After the heavy metal supplement and alum are added to the treatment tank 4, the stirring rod 11 is rotated by driving the motor 8, which helps to improve the mixing reaction of the heavy metal supplement and alum with the wastewater. After standing for more than 2 hours, the threaded rod 16 is rotated by driving the second electric motor 15 to rotate, which causes the partition 13 to slide along the slide 17 and transport it to the lower part of the treatment tank 4. The water is disinfected by driving the ozone generator 7. After disinfection for 30 minutes, the disinfected water is input into the storage tank 6 through the delivery pipe 3 by driving the second water pump 5 to store the treated water, which is beneficial for further wastewater treatment, improves the utilization rate of wastewater, and helps to reduce the operating cost of the pure water machine.
