Description

Technical Field

[0001] This utility model relates to the field of green building technology, specifically to a water circulation device for green buildings. Background Technology

[0002] Green building refers to buildings that, throughout their entire life cycle, maximize resource conservation (energy saving, land saving, water saving, and material saving), protect the environment, and reduce pollution, providing people with healthy, suitable, and efficient living spaces, and coexisting harmoniously with nature. The water recycling system in green buildings is a key piece of equipment dedicated to achieving efficient water resource recycling within green buildings. Its core objective is to collect, treat, and redistribute various water resources within the building to reduce dependence on external water supply and simultaneously minimize the environmental impact of wastewater discharge.

[0003] However, existing technologies still have the following problems: In terms of water resource utilization, traditional buildings mostly rely on urban water supply systems, directly introducing clean water resources from outside for various water needs within the building, such as sanitation and landscaping irrigation. Wastewater generated after water use is discharged directly without effective treatment, leading to a huge waste of water resources and exacerbating environmental pollution problems. In some existing building water circulation devices, rainwater filtration is an important part of water circulation treatment. Common impurities in rainwater, such as leaves and mud, cannot be efficiently intercepted and treated, making it difficult for the treated water quality to meet the diverse water needs within the building. On the other hand, the filter screen is easily clogged by impurities and lacks an effective self-cleaning mechanism, requiring frequent manual cleaning or replacement. At the same time, the sewage system is poorly designed and cannot flexibly adjust the sewage flow rate according to water quality conditions. Utility Model Content

[0004] In order to solve the problems of water resources being unusable and the inconvenience of regulating sewage discharge, the purpose of this utility model is to provide a water recycling device for green buildings.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a water circulation device for green buildings, including a base, a filter device fixedly installed on the upper surface of the base, a conveying pipe and an adjusting device fixedly connected to one side of the filter device, a water pump fixedly installed at one end of the conveying pipe, the output end of the water pump fixedly connected to the conveying pipe, and a rainwater pipe fixedly connected to the input end of the water pump. The filter device includes a barrel, a motor fixedly installed on the upper surface of the barrel, the output end of the motor passing through the barrel and fixedly fitted with a vortex propeller, an inlet, an outlet, and a drain outlet respectively opened on the outer surface of the barrel, a stainless steel filter screen fixedly connected inside the barrel, and a rainwater hopper fixedly installed at the lower end of the stainless steel filter screen.

[0006] Preferably, the regulating device includes a valve body with an inlet and an outlet at both ends. One end of the inlet is fixedly connected to a drain outlet. A packing valve cover is fixedly installed on the upper surface of the valve body. A valve stem is threaded into the upper end of the packing valve cover. A handwheel is fixedly sleeved on the upper end of the valve stem. A valve core is fixedly connected to the bottom end of the valve stem. The valve core is located inside the inlet.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] This invention utilizes a combination of a filtration device and an adjustment device. Under the action of a vortex propeller, rainwater first undergoes gravity sedimentation, causing large particles of impurities to settle. Then, a stainless steel filter screen performs fine filtration, effectively intercepting various impurities such as leaves and silt in the wastewater. Due to the ingenious design of the outlet and discharge flow rates, the wastewater forms vortex and turbulence within the stainless steel filter screen, automatically cleaning the screen and effectively preventing impurities from clogging it and affecting its filtration performance. The adjustment device can flexibly adjust the discharge flow rate according to the degree of wastewater pollution. When the pollution level is high, such as at the beginning of rainfall, the wastewater discharge flow rate is increased to prevent a large amount of pollutants from entering the subsequent circulation. After the water quality improves, the discharge volume is reduced to increase the water purification rate, further improving the efficiency of water resource utilization and enabling the device to better adapt to different water quality conditions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3 As shown, this utility model provides a water circulation device for green buildings, including a base 11. A filter device 12 is fixedly installed on the upper surface of the base 11. A conveying pipe 13 and an adjusting device 16 are fixedly connected to one side of the filter device 12. A water pump 14 is fixedly installed at one end of the conveying pipe 13. The output end of the water pump 14 is fixedly connected to the conveying pipe 13, and the input end of the water pump 14 is fixedly connected to a rainwater pipe 15. Multiple support legs are fixedly installed at the bottom of the base 11, and the multiple support legs are distributed in a rectangular array to stably support the entire water circulation device and ensure that the device remains stable during use. The filter device 12 includes a barrel 17. A motor 18 is fixedly installed on the upper surface of the barrel 17. The output end of the motor 18 passes through the barrel 17 and is fixedly sleeved with a swirl propeller 19. The swirl propeller 19 is located above the stainless steel filter screen 23, and multiple swirl propeller blades are fixedly installed on the outer surface of the swirl propeller 19 in a ring array. The motor 18 drives the swirl propeller 19 to rotate. The swirl propeller blades drive the water flow to rotate, generating centrifugal force, which can more effectively separate impurities in rainwater and improve filtration efficiency.

[0016] The outer surface of the barrel 17 is provided with an inlet 20, an outlet 21, and a drain 22. One end of the inlet 20 is connected to the delivery pipe 13, allowing rainwater pumped by the water pump 14 to smoothly enter the barrel 17 for filtration. A clean water pipe 25 is fixedly installed at one end of the outlet 21, through which the filtered clean rainwater can be delivered to the place where it is needed. The outlet 21 is located above the drain 22, which is located at the bottom of the barrel 17. The diameter of the drain 22 is smaller than that of the outlet. The diameter of the outlet 21 is designed to allow heavier impurities to settle to the bottom of the barrel 17 during the filtration process and be discharged through the smaller diameter drain outlet 22, while clean rainwater flows out from the upper outlet 21. A stainless steel filter screen 23 is fixedly connected inside the barrel 17, and a rainwater hopper 24 is fixedly installed at the lower end of the stainless steel filter screen 23. The rainwater hopper 24 is conical, and a discharge port is opened at the bottom of the rainwater hopper 24. The conical rainwater hopper 24 can better collect the settled impurities and discharge them through the discharge port. The regulating device 16 includes a valve body 26, with an inlet 31 and an outlet 32 ​​at both ends. One end of the inlet 31 is fixedly connected to the drain port 22. A valve seat is fixedly installed inside the valve body 26. The valve seat works in conjunction with the valve core 30. The flow rate and speed of the drain can be adjusted by controlling the opening and closing degree of the valve core 30 and the valve seat. A packing valve cover 27 is fixedly installed on the upper surface of the valve body 26. A valve stem 28 is threaded into the upper end of the packing valve cover 27. A handwheel 29 is fixedly sleeved on the upper end of the valve stem 28. The valve core 30 is fixedly connected to the bottom end of the valve stem 28. The valve core 30 is located inside the inlet 31. The operator can control the position of the valve core 30 by rotating the handwheel 29 to move the valve stem 28 up and down, thereby realizing the opening and closing of the regulating device 16 and the flow rate regulation.

[0017] Working principle: Rainwater mixed with impurities is pumped into the tank 17 of the filter device 12 through the delivery pipe 13 by the power provided by the water pump 14 via the rainwater pipe 15. At the same time, the motor 18 starts, and its output end drives the vortex propeller 19 to rotate at high speed, causing the sewage that has just entered the tank 17 to quickly begin to swirl. During the swirling process of the sewage, various impurities carried in it, such as leaves and silt, begin to settle under the combined action of gravity and the centrifugal force generated by the swirling. As time goes by, these impurities gradually move towards the rainwater hopper 24 at the bottom of the tank 17. Due to the special arc surface structure of the rainwater hopper 24, when the impurities come into contact with its arc surface, they will be further accelerated to swirl downwards by their own gravity and the propulsion of the water flow, and quickly gather at the bottom of the rainwater hopper 24. The wastewater is discharged from the discharge port. During this process, the outlet 21 is located above the drain port 22, and the flow rate of the drain port 22 is less than that of the outlet 21. This causes the wastewater to form a unique swirling and turbulent state within the stainless steel filter screen 23, which enables the filter screen to self-clean and effectively prevents the filter screen from being clogged by impurities, thus reducing the filtration efficiency. The drain port 22 is located at the bottom of the tank 17. This position design is conducive to the maximum accumulation of impurities under the action of gravity. When there is no continuous flow of wastewater into the inlet 20, the wastewater remaining inside the tank 17 will be quickly discharged from the drain port 22 under the drive of gravity. When it is necessary to adjust the discharge volume, the valve body 26 is provided with an inlet 31 and an outlet 32 ​​at both ends, respectively. The inlet 31 is connected to the drain port 22. When the operator turns the handwheel 29, the valve stem 28 will rotate accordingly. Because the valve stem 28 and the packing cover 27 are threaded together, this structure allows the valve stem 28 to move up and down axially while rotating. When the valve stem 28 moves the valve core 30 upward, the gap between the valve core 30 and the valve seat increases, and the water flow channel area between the inlet 31 and the outlet 32 ​​increases, thereby increasing the sewage flow rate from the drain port 22 through the valve body 26. Conversely, when the handwheel 29 is turned to move the valve stem 28 downward, the valve core 30 gradually approaches the valve seat, the gap between them decreases, the water flow channel area decreases, and the sewage flow rate decreases accordingly. In this way, the regulating device 16 achieves flexible adjustment of the sewage flow rate. In the stage of high sewage pollution, such as the initial stage of rainfall, the sewage flow rate can be adjusted to the maximum by the regulating device 16 to increase the sewage discharge rate and prevent a large amount of highly polluted sewage from entering the subsequent water circulation system. As the sewage quality gradually improves with the treatment process, the discharge volume of the regulating device 16 can be reduced accordingly to improve the overall water purification rate of the device and achieve efficient utilization of water resources.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
