Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of wastewater treatment technology, and more specifically, to a multi-stage wastewater treatment device. Background Technology

[0002] Wastewater generally refers to wastewater discharged from domestic and industrial processes that has been polluted to a certain extent. Wastewater mainly includes domestic sewage, industrial wastewater, and initial rainwater. The main pollutants in wastewater include pathogens, oxygen-consuming pollutants, plant nutrients, and toxic pollutants. In order to prevent wastewater from polluting the surrounding environment after discharge, it is necessary to filter the wastewater through wastewater treatment equipment.

[0003] When wastewater treatment equipment filters wastewater, larger particulate pollutants can be filtered out, but smaller particulate pollutants are difficult to filter. This makes it difficult to filter pollutants comprehensively during wastewater treatment. In order to filter out smaller particulate pollutants, multiple filter plates of different sizes are usually added to the filter tank to perform multi-stage filtration of wastewater. However, after a long period of use, the filter plates are easily clogged by pollutants. Cleaning requires disassembling the filter plates one by one. This method is not only time-consuming and labor-intensive, but also reduces the efficiency of wastewater filtration. Utility Model Content

[0050] like Figures 1-4 As shown, a multi-stage wastewater treatment device according to an embodiment of this disclosure is illustrated. It includes a treatment tank 1, and further comprises: filter plates 2, a cleaning frame 3, rubber scrapers 4, a moving mechanism, a cleaning mechanism, and a discharge mechanism. Two support frames 22 are fixedly connected to the bottom of the treatment tank 1 to support it above the water pump 10. An inlet pipe 18 is connected to the treatment tank 1, and a collection box 19 is connected to the inlet pipe 18. Multiple filter plates 2 of different specifications are provided and are all disposed within the treatment tank 1. The cleaning frame 3 is located at the top of the treatment tank 1. Two rubber scrapers 4 are provided and are fixedly connected within the cleaning frame 3. The moving mechanism drives the multiple filter plates 2 to move and arrange within the treatment tank 1. During the movement of the filter plates 2 of different specifications, multi-stage filtration of wastewater is achieved. When cleaning is required, the filter plates 2 need to be moved above the transmission belt 6. The cleaning mechanism allows for rapid cleaning of the filter plates 2, saving time and effort and improving wastewater filtration efficiency.

[0051] The moving mechanism is located inside the treatment tank 1 and is used to drive multiple filter plates 2 to move and arrange within the treatment tank 1. The moving mechanism includes a moving shaft 5, a transmission belt 6, and a first motor 7. A support plate 21 is fixedly connected inside the treatment tank 1, and the top of the support plate 21 contacts the transmission belt 6. There are two moving shafts 5, both of which are rotatably connected inside the treatment tank 1. The transmission belt 6 is driven between the two moving shafts 5, and multiple filter plates 2 are fixedly connected to the transmission belt 6. The first motor 7 is installed on one side of the treatment tank 1, and the output end of the first motor 7 passes through the treatment tank 1 and is fixedly connected to one end of one of the moving shafts 5. Specifically, the first motor 7 drives the moving shaft 5 to rotate, and the transmission belt 6 of the moving shaft drives multiple filter plates 2 to move and arrange within the treatment tank 1, thereby performing multi-stage filtration of the wastewater in the treatment tank 1.

[0052] The cleaning mechanism is mounted on the processing box 1 and is used to drive the cleaning frame 3 and rubber scraper 4 to clean the filter plate 2. The cleaning mechanism includes: a fixed plate 8, a slider 9, a drive assembly, and a spray assembly. A slide rod 20 is fixedly connected between the two fixed plates 8. The slider 9 has a sliding hole, and the slide rod 20 is slidably connected in the sliding hole. There are two fixed plates 8, both of which are fixedly connected to the top of the processing box 1. The slider 9 is slidably connected between the two fixed plates 8. The cleaning frame 3 is fixedly connected to the bottom of the slider 9. The drive assembly is mounted on the fixed plate 8 and is used to drive the slider 9 to move. The spray assembly is mounted on one of the fixed plates 8 and is used to spray the filter plate 2. The drive assembly includes: a moving screw 13 and a second motor 14. The moving screw 13 is rotatably connected between the two fixed plates 8. The slider 9 has a screw hole, and the moving screw 13 is threaded into the screw hole. The second motor 14 is mounted on one of the fixed plates 8. The output end of the spray assembly passes through the fixed plate 8 and is fixedly connected to one end of the moving screw 13. The spray assembly includes: a delivery pump 15, a pipe rack 16, and a nozzle 17. The delivery pump 15 is installed on one side of the treatment box 1, and the input end of the delivery pump 15 is connected to the treatment box 1. The pipe rack 16 is fixedly connected to one of the fixed plates 8, and the bottom end of the pipe rack 16 is connected to the output end of the delivery pump 15. There are two nozzles 17, and the two nozzles 17 are connected to the pipe rack 16. Specifically, when the filter plate 2 needs to be cleaned, the filter plate 2 to be cleaned is stopped between the two fixed plates 8. Then, the moving screw 13 is rotated by the second motor 14, which in turn drives the slider 9 and the cleaning frame 3 to move. When the cleaning frame 3 moves, it drives the rubber scraper 4 to scrape the impurities on both sides of the filter plate 2. The water in the treatment box 1 is drawn out by the delivery pump 15 and transported by the pipe rack 16. The water is sprayed onto the filter plate 2 by the nozzle 17, thereby spraying off the pollutants on the filter plate 2.

[0053] The discharge mechanism is located at the bottom of the treatment tank 1 and is used to discharge the filtered wastewater. The discharge mechanism includes a water pump 10, a delivery pipe 11, and a discharge pipe 12. The water pump 10 is installed at the bottom of the treatment tank 1. One end of the delivery pipe 11 is connected to the input end of the water pump 10, and the other end of the delivery pipe 11 is connected to the treatment tank 1. The discharge pipe 12 is connected to the output end of the water pump 10. Specifically, the water filtered in the treatment tank 1 is pumped out by the water pump 10 and the delivery pipe 11, and the filtered water is discharged through the discharge pipe 12.

[0054] In this embodiment, current wastewater treatment equipment requires disassembling and cleaning each filter plate 2 of different specifications, which is time-consuming and labor-intensive. In this application, wastewater is added into the treatment tank 1 through the collection box 19 and the inlet pipe 18. Then, the first motor 7 drives the moving shaft 5 to rotate, and the transmission belt 6 of the moving belt moves multiple filter plates 2 to arrange and move them in the treatment tank 1, thereby performing multi-stage filtration of the wastewater in the treatment tank 1. When it is necessary to clean the filter plates 2, the filter plates 2 that need to be cleaned are stopped at two fixed points. Between the plates 8, the second motor 14 drives the moving screw 13 to rotate, which in turn drives the slider 9 and the cleaning frame 3 to move. When the cleaning frame 3 moves, it drives the rubber scraper 4 to scrape off the impurities on both sides of the filter plate 2. The water in the treatment tank 1 is drawn out by the delivery pump 15 and transported through the pipe rack 16. The water is sprayed onto the filter plate 2 through the nozzle 17, thereby spraying off the pollutants on the filter plate 2. Then, the filtered water in the treatment tank 1 is drawn out by the water pump 10 and the delivery pipe 11 and discharged through the discharge pipe 12.
