Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a wastewater treatment device for green buildings. Background Technology

[0002] Green building refers to buildings that, throughout their entire life cycle, maximize resource conservation, environmental protection, and pollution reduction, providing people with healthy, suitable, and efficient living spaces, and coexisting harmoniously with nature.

[0003] To reduce the environmental pollution caused by green buildings, wastewater treatment equipment is used to treat the wastewater generated by the buildings, making it reusable. The wastewater treatment process mainly includes wastewater collection, pretreatment, biological treatment, and advanced treatment. Pretreatment mainly filters out impurities from the wastewater to facilitate subsequent treatment. However, when existing wastewater treatment equipment filters wastewater, the filtered impurities accumulate on the aluminum plates, reducing the filtration efficiency of the aluminum plates.

[0004] Therefore, this utility model provides a wastewater treatment device for green buildings. Utility Model Content

[0009] Preferably, a cleaning rod is slidably connected to the middle of the accumulation tank; a float is fixed to the side wall of the cleaning rod; the above structure can improve the discharge effect of impurities inside the accumulation tank and reduce the occurrence of corrosion caused by impurities adhering to the inner side wall of the accumulation tank for a long time.

[0010] Preferably, a limiting ring is fixedly connected to the middle of the connecting pipe; the diameter of the limiting ring is smaller than the diameter of the counterweight ball; through the above structure, the occurrence of the blocking plug emerging from the top of the connecting pipe due to excessive water flow impact can be reduced.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 2As shown, an embodiment of the present invention provides a wastewater treatment device for green buildings, comprising a treatment tank 1; a transfer tank 12 fixedly connected to the bottom of the treatment tank 1; a filter plate 13 fixedly connected to the bottom of the treatment tank 1; a support 14 fixedly connected to the top of the treatment tank 1; a motor 15 fixedly connected to the top of the support 14; a drive shaft 16 fixedly connected to the output end of the motor 15; a shaft rod 17 slidably connected to the bottom of the drive shaft 16; and a first scraper 18 fixedly connected to the bottom end of the shaft rod 17. During operation, construction wastewater is fed into the treatment tank 1. Larger impurities in the wastewater are blocked by the filter plate 13, allowing wastewater with fewer impurities to fall into the transfer tank 12 and then be discharged. Over time... As the filter moves, impurities accumulate on the top of the filter plate 13. At this point, the motor 15 can be started to drive the drive shaft 16 and shaft 17 to rotate, which in turn drives the first scraper 18 to rotate and scrape the upper surface of the filter plate 13, causing the impurities accumulated on the filter plate 13 to leave the filter plate 13. At the same time, the rotating first scraper 18 can stir the sewage inside the treatment tank 1, thereby increasing the sewage filtration speed. Through the above structure, the impurities accumulated on the top of the filter plate 13 due to filtration can be cleaned, making it difficult for them to accumulate and thus affecting the filtration speed. At the same time, the sewage inside the treatment tank 1 is stirred, thereby increasing the sewage filtration speed.

[0024] like Figures 1 to 3 As shown, a sedimentation tank 2 is provided on the side wall of the treatment tank 1; an inlet tank 21 is provided in the middle of the treatment tank 1; an outlet tank 22 is provided in the middle of the treatment tank 1; both the inlet tank 21 and the outlet tank 22 are connected to the sedimentation tank 2 and the interior of the treatment tank 1; a filter screen 23 is fixedly connected to the middle of the outlet tank 22; an electric cylinder 24 is fixedly connected to the top of the treatment tank 1; a partition 25 is fixedly connected to the output end of the electric cylinder 24; the partition 25 is slidably installed in the middle of the inlet tank 21 and the outlet tank 22; a pumping pipe 26 is fixedly connected to the top of the sedimentation tank 2; during operation, as the first scraper 18 stirs the sewage, the sewage will rotate and flow, carrying some of the sediment with it. Impurities enter the interior of the accumulation tank 2 through the inlet tank 21, and then flow back into the treatment tank 1 through the outlet tank 22. During this process, some impurities in the sewage are blocked by the filter screen 23 and remain inside the accumulation tank 2. After a period of time, the electric cylinder 24 is activated to drive the baffle 25 to descend, thereby closing the inlet tank 21 and the outlet tank 22. Then, the pumping mechanism is used to pump out the sewage containing impurities from the accumulation tank 2 through the pumping pipe 26. Through the above structure, the impurities accumulated inside the equipment can be automatically cleaned every once in a period of time, reducing the occurrence of a decrease in processing speed caused by excessive impurities inside the equipment.

[0025] like Figures 1 to 4As shown, a water storage baffle 3 is fixedly connected to the middle of the transfer tank 12; a connecting pipe 31 is fixedly connected to the top of the transfer tank 12; the connecting pipe 31 is connected to the bottom of the sedimentation tank 2; a fixing ring 32 is fixedly connected to the middle of the connecting pipe 31; a blocking plug 33 is slidably connected to the middle of the connecting pipe 31; a counterweight ball 34 is fixedly connected to the bottom end of the blocking plug 33; during operation, when the sewage and impurities inside the sedimentation tank 2 are pumped out, a negative pressure will be formed inside the sedimentation tank 2, at which time the blocking plug 33 will rise and... Opening the fixing ring 32 allows the wastewater with fewer impurities on one side of the water storage baffle 3 inside the transfer tank 12 to be pumped into the sedimentation tank 2. Then, it is pumped out by the pumping pipe 26 along with the impurities inside the sedimentation tank 2. Through the above structure, when the impurities inside the sedimentation tank 2 are being pumped out, some of the wastewater with fewer impurities inside the transfer tank 12 can rise into the sedimentation tank 2 to flush the impurities inside the sedimentation tank 2, thereby reducing the residue of impurities inside the sedimentation tank 2 and improving the cleaning effect of impurities.

[0026] like Figure 3 As shown, a cleaning rod 4 is slidably connected to the middle of the accumulation tank 2; a float 41 is fixed to the side wall of the cleaning rod 4; during operation, as the side wall of the accumulation tank 2 is soaked in sewage for a long time, some impurities will adhere to the inner side wall of the accumulation tank 2. When the sewage inside the accumulation tank 2 is pumped out using the pumping pipe 26, the float 41 and the cleaning rod 4 will descend with the liquid level, thereby scraping off some of the impurities attached to the inner side wall of the accumulation tank 2. Through the above structure, the discharge effect of impurities inside the accumulation tank 2 can be improved, and the corrosion caused by impurities adhering to the inner side wall of the accumulation tank 2 for a long time can be reduced.

[0027] like Figure 4 As shown, a limiting ring 5 is fixed to the middle of the connecting pipe 31; the diameter of the limiting ring 5 is smaller than the diameter of the counterweight ball 34; during operation, when the blocking plug 33 rises, the counterweight ball 34 will be blocked by the limiting ring 5, so that the blocking plug 33 cannot completely emerge from the top of the connecting pipe 31. Through the above structure, the occurrence of the blocking plug 33 emerging from the top of the connecting pipe 31 due to excessive water flow impact can be reduced.

[0028] like Figures 1 to 2 As shown, a lifting ring 6 is fixed to the bottom of the bracket 14; a fixing hook 61 is fixed to the top of the shaft 17. During operation, after prolonged use, the middle part of the first scraper 18 may be entangled with filamentous debris, causing the bottom of the first scraper 18 to not fully adhere to the top of the filter plate 13 and clean the filter plate 13. At this time, the shaft 17 can be lifted upwards, and the fixing hook 61 can be hung on the middle part of the lifting ring 6 to clean the first scraper 18 that is out of the water surface. With the above structure, the debris attached to the middle part of the first scraper 18 can be easily cleaned, reducing the impact of debris on the cleaning effect of the first scraper 18.

[0029] like Figure 2As shown, a second scraper 7 is fixedly connected to the top end of the first scraper 18; the second scraper 7 is disposed in contact with the inner wall of the treatment tank 1; through the above structure, the inner wall of the treatment tank 1 can be cleaned, reducing the occurrence of impurities adhering to the inner wall of the treatment tank 1, thereby reducing the corrosion caused by long-term adhesion of impurities to the treatment tank 1.

[0030] During operation, construction wastewater is fed into treatment tank 1. Larger impurities in the wastewater are blocked by filter plate 13, while wastewater with fewer impurities falls into transfer tank 12 and is then discharged. Over time, impurities accumulate on the filter plate 13. At this point, motor 15 is started to drive drive shaft 16 and shaft 17 to rotate, which in turn drives first scraper 18 to rotate and scrape the upper surface of filter plate 13, causing the accumulated impurities on filter plate 13 to leave the filter plate 13. At the same time, the rotating first scraper 18 can also clean the wastewater inside treatment tank 1. Stirring increases the filtration speed of the wastewater. As the first scraper 18 stirs the wastewater, it rotates and flows, carrying some impurities through the inlet tank 21 into the sedimentation tank 2, and then flows back into the treatment tank 1 from the outlet tank 22. During this process, some impurities in the wastewater are blocked by the filter screen 23 and remain inside the sedimentation tank 2. After a period of time, the electric cylinder 24 is activated to lower the baffle 25, closing the inlet tank 21 and the outlet tank 22. Then, the pumping mechanism is used to pump out the wastewater containing impurities from inside the sedimentation tank 2 through the pumping pipe 26. When the sewage and impurities inside the sedimentation tank 2 are pumped out, a negative pressure will be formed inside the sedimentation tank 2. At this time, the blocking plug 33 will rise and open the fixing ring 32, so that the sewage with fewer impurities on the side of the water storage baffle 3 inside the transfer tank 12 will be pumped into the sedimentation tank 2. Then, it will be pumped out by the pumping pipe 26 along with the impurities inside the sedimentation tank 2. As the side wall of the sedimentation tank 2 is soaked in sewage for a long time, some impurities will adhere to the inner side wall of the sedimentation tank 2. When the sewage inside the sedimentation tank 2 is pumped out by the pumping pipe 26, the float 41 and the cleaning rod 4 will move with the liquid level. The water level drops, scraping off some of the impurities attached to the inner wall of the accumulation tank 2. When the blocking plug 33 rises, the counterweight ball 34 will be blocked by the limiting ring 5, preventing the blocking plug 33 from completely emerging from the top of the connecting pipe 31. After long-term use, the middle of the first scraper 18 may be entangled with filamentous debris, causing the bottom of the first scraper 18 to not fully adhere to the top of the filter plate 13 and clean the filter plate 13. At this time, the shaft 17 can be lifted upwards and the fixing hook 61 can be hung in the middle of the hanging ring 6 to clean the first scraper 18 that is out of the water surface.
