Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a multi-stage separation and treatment device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. Harmful substances in wastewater, such as heavy metals, chemicals, bacteria, and viruses, will have long-term negative impacts on soil, water sources, and ecosystems if discharged directly without treatment. Wastewater treatment can significantly reduce the concentration of these harmful substances in the environment, thereby protecting the health and stability of the ecosystem.

[0003] Some multi-stage separation equipment for wastewater treatment still has some problems. For example, during wastewater treatment, solid impurities in the wastewater will settle inside the treatment tank, making it inconvenient to discharge the settled impurities. This can easily cause impurities to clog the inside of the discharge outlet, which can affect the treatment efficiency.

[0004] Therefore, we propose a multi-stage separation and treatment equipment for wastewater treatment to improve the above-mentioned problems. Utility Model Content

[0016] (1) By setting a second motor, a feed port, a screw conveyor shaft, a blocking plate, a rotating shaft, a third motor and a discharge port, the guide plate will guide the precipitated impurities into the interior of the conveying shell through the feed port. When it is necessary to discharge the precipitated impurities, the second motor and the third motor will be started at the same time.

[0025] Please see Figure 1-4 The present invention provides an embodiment of a multi-stage separation and treatment device for wastewater treatment, including a connecting seat 1, a treatment box 4 is provided on the left side of the top of the connecting seat 1, a filter box 17 is provided on the right side of the top of the connecting seat 1, support legs 2 are fixedly connected between the four corners between the treatment box 4 and the connecting seat 1, a reserved opening is provided at the top of the inner side wall of the treatment box 4, and a sewage discharge structure is provided at the bottom of the treatment box 4 to facilitate the discharge of sedimented impurities.

[0026] The sewage discharge structure includes a conveying shell 3, a guide plate 5, and a screw conveyor shaft 29. The guide plate 5 is fixedly connected to the bottom of the inner side wall of the treatment box 4. An inlet 28 is opened on the left side of the bottom of the treatment box 4. The conveying shell 3 is installed on the left side of the bottom of the treatment box 4. A second motor 27 is installed on the left side of the conveying shell 3. The output end of the second motor 27 is fixedly connected to the screw conveyor shaft 29. A discharge port 33 is fixedly connected to the right side of the bottom of the conveying shell 3. A third motor 32 is installed on the left side of the bottom of the conveying shell 3. A rotating shaft 31 is fixedly connected to the output end of the third motor 32. A blocking plate 30 is installed at the bottom of the rotating shaft 31.

[0027] A first motor 6 is installed on the left side of the processing box 4. The output end of the first motor 6 is fixedly connected to a stirring shaft 13. The upper and lower ends of the stirring shaft 13 are fixedly connected to stirring rods 12. The stirring shaft 13 is movably connected inside the processing box 4. The spiral conveyor shaft 29 is movably connected inside the conveyor shell 3. The right side of the block plate 30 is set at the bottom of the discharge port 33.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the guide plate 5 guides the precipitated impurities into the interior of the conveying shell 3 through the feed inlet 28. When it is necessary to discharge the precipitated impurities, the second motor 27 and the third motor 32 are started simultaneously. The third motor 32 drives the blocking plate 30 to rotate through the rotating shaft 31, so that the blocking plate 30 is turned open from the bottom end of the discharge port 33. The second motor 27 drives the screw conveyor shaft 29 to rotate inside the conveying shell 3, so that the impurities can be discharged from the interior of the processing box 4 and the conveying shell 3 through the screw conveyor shaft 29. When it is necessary to seal the bottom end of the discharge port 33, the third motor 32 is started again to rotate the blocking plate 30 to the bottom end of the discharge port 33.

[0029] Support frames 7 are fixedly connected to the top of both sides of the processing box 4. A protective shell 9 is installed between the top of the support frames 7. A servo motor 8 is installed at the top of the left side of the support frame 7. A threaded rod 37 is fixedly connected to the output end of the servo motor 8. A threaded sleeve 10 is provided on the outside of the threaded rod 37. A hydraulic cylinder 11 is installed at the bottom of the threaded sleeve 10.

The threaded rod 37 is installed inside the protective shell 9. The threaded sleeve 10 and the threaded rod 37 cooperate with each other.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, the hydraulic cylinder 11 is activated, and the hydraulic cylinder 11 drives the second storage box 35 to descend through the connecting plate 36, causing the second storage box 35 to descend into the processing box 4. A liquid sensor is installed inside the second storage box 35. After the second storage box 35 descends to the appropriate position, the servo motor 8 is activated. The servo motor 8 drives the threaded rod 37 to rotate, causing the threaded sleeve 10 to move the second storage box 35 and the connecting plate 36 at the top inside the processing box 4, thereby collecting the impurities floating at the top inside the processing box 4 and processing the floating impurities uniformly.

[0031] A water pump 25 is installed at the top between the treatment box 4 and the filter box 17. A water pump pipe 26 is fixedly connected to the input end of the water pump 25, and a water outlet pipe 15 is fixedly connected to the output end of the water pump 25. A nozzle 16 is installed at the bottom end of the water outlet pipe 15. Support blocks 14 are installed on both sides of the top of the filter box 17, and the support blocks 14 are located on both sides of the bottom end of the water outlet pipe 15.

[0032] Inside the filter box 17, on the right side, a filter screen plate 19 and an activated carbon filter plate 20 are movably hinged. Hinges 23 are fixedly connected to the left sides of the upper and lower ends of the filter screen plate 19 and the left side of the top of the activated carbon filter plate 20. Hinges 22 are movably hinged between the hinges 23. There are two sets of filter screen plates 19. The activated carbon filter plate 20 is located at the bottom of the filter screen plate 19. A fourth motor 34 is installed at the bottom left of the rear end of the filter box 17. The output end of the fourth motor 34 is fixedly connected to the hinges 23. A rotating block 24 is fixedly connected to the front end of the hinges 23. The rotating block 24 is located on the left side of the bottom end of the activated carbon filter plate 20. A support plate 21 is fixedly connected to the right side of the filter box 17. There are three sets of support plates 21. A first storage box 18 is located at the top of the support plate 21.

[0033] Specifically, such as Figure 1 and Figure 3 As shown, the water pump 25 is started. The water pump 25 draws water from the inside of the treatment tank 4 into the inside of the filter tank 17 through the water suction pipe 26, the water outlet pipe 15 and the nozzle 16. Multiple sets of nozzles 16 can disperse the water onto the top of the filter screen plate 19. The filter screen plate 19 and the activated carbon filter plate 20 can improve the filtration effect. When it is necessary to tilt the filter screen plate 19 and the activated carbon filter plate 20, the fourth motor 34 is started. The fourth motor 34 drives the rotating block 24 to rotate through the hinge block 23, so that the filter screen plate 19 and the activated carbon filter plate 20 are tilted, so that the impurities of the filter screen plate 19 and the activated carbon filter plate 20 can slide into the inside of the first storage tank 18, and the impurities at the top of the filter screen plate 19 and the activated carbon filter plate 20 are collected.

[0034] Working Principle: In use, the wastewater treatment agent is placed inside the treatment tank 4. After placement, the first motor 6 is started. The first motor 6 drives the stirring rod 12 to rotate inside the treatment tank 4 via the stirring shaft 13, thus ensuring uniform mixing of the wastewater treatment agent and wastewater. After uniform mixing, the wastewater is allowed to settle, allowing impurities in the wastewater to settle and float. After the wastewater has settled for a period of time, the hydraulic cylinder 11 is activated. Because a pre-reserved opening is provided at the top of the inner wall of the treatment tank 4, and the second storage tank 35 is located at the top of the treatment tank 4, activating the hydraulic cylinder 11 allows it to move smoothly through the continuous flow of water. The connecting plate 36 lowers the second storage tank 35 into the processing tank 4. A liquid sensor is installed inside the second storage tank 35. Once the second storage tank 35 reaches the appropriate position, the servo motor 8 is activated. The servo motor 8 drives the threaded rod 37 to rotate, causing the threaded sleeve 10 to move the second storage tank 35 and the connecting plate 36 to the top of the processing tank 4. This allows for the collection of floating impurities from the top of the processing tank 4, which are then processed uniformly. After processing the floating impurities, the water pump 25 is activated. The water pump 25 pumps water from the processing tank 4 through the suction pipe 26, the outlet pipe 15, and the nozzle 16. Water is drawn into the filter box 17. Multiple spray nozzles 16 are installed to disperse the water onto the top of the filter screen 19. The filter screen 19 and activated carbon filter 20 can improve the filtration effect. When the filter screen 19 and activated carbon filter 20 need to be tilted, the fourth motor 34 is activated. The fourth motor 34 drives the rotating block 24 to rotate through the hinge block 23, causing the filter screen 19 and activated carbon filter 20 to tilt. This allows impurities on the filter screen 19 and activated carbon filter 20 to slide into the first storage box 18, collecting the impurities on the top of the filter screen 19 and activated carbon filter 20. The guide plate 5 guides the precipitated impurities into the interior of the conveying shell 3 through the feed inlet 28. When it is necessary to discharge the precipitated impurities, the second motor 27 and the third motor 32 are started simultaneously. The third motor 32 drives the blocking plate 30 to rotate through the rotating shaft 31, so that the blocking plate 30 is turned open from the bottom end of the discharge port 33. The second motor 27 drives the screw conveyor shaft 29 to rotate inside the conveying shell 3, so that the impurities can be discharged from the interior of the processing box 4 and the conveying shell 3 through the screw conveyor shaft 29. When it is necessary to seal the bottom end of the discharge port 33, the third motor 32 is started again to rotate the blocking plate 30 to the bottom end of the discharge port 33.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
