Description

Technical Field

[0001] This utility model relates to the field of rainwater treatment technology, and in particular to a rainwater recycling biological treatment oxygenation component. Background Technology

[0002] The global water shortage problem is becoming increasingly serious. With population growth, industrialization and urbanization, the demand for water resources is constantly increasing, while the available freshwater resources are limited. As a potential usable water resource, rainwater recycling has received increasing attention. By collecting and treating rainwater for reuse, the water shortage situation can be effectively alleviated, and water sources can be provided for non-potable water needs such as urban greening irrigation, landscape water replenishment and toilet flushing.

[0003] Existing rainwater harvesting and storage tanks are not always used. Some tanks store the water for later use. This long-term storage of water in the tanks leads to stagnant water, which becomes very poor in quality and produces a lot of microorganisms, resulting in industrial water quality failing to meet standards. Therefore, we propose a rainwater harvesting and recycling device.

[0004] Existing patent (publication number: CN222064251U) discloses a rainwater collection and recycling device, comprising: a water storage tank, a support plate fixedly installed on one end of the upper surface of the water storage tank, an oxygenation component provided on the support plate, the oxygenation component including a drive motor fixedly installed on the upper surface of the support plate, a stirring rod fixedly installed on one end of the output shaft of the drive motor, the stirring rod having multiple sets of stirring blades arrayed on its surface, a filter tank located on one side of the water storage tank, a base, a recycling tank fixedly installed on one end of the upper surface of the base, and a water filtration tank installed on the other end of the upper surface of the base, the water filtration tank being connected to both the filter tank and the recycling tank. This invention features a device that, when started by a drive motor, one end of the drive motor's output shaft begins to rotate, subsequently driving the stirring rod to rotate, which in turn drives the stirring blades to agitate and oxygenate the water inside the water storage tank, thereby reducing the increase of microorganisms.

[0005] To address the aforementioned problems, existing patents have provided solutions. However, existing rainwater harvesting devices lack a structure that circulates the rainwater while simultaneously oxygenating it. This leads to localized hypoxia in the water, inhibiting the activity of aerobic microorganisms, affecting the stability and processing capacity of the biological treatment system. Consequently, the treated rainwater quality fails to meet reuse standards, hindering the full utilization of biological treatment and reducing the efficiency of pollutant removal and rainwater purification.

[0006] To address this, a rainwater recycling biological treatment and oxygenation component is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a rainwater harvesting and biological treatment oxygenation component, which solves the problem that existing rainwater harvesting devices lack a structure that simultaneously oxygenates and circulates rainwater, leading to localized oxygen deficiency in the water body, inhibiting the activity of aerobic microorganisms, affecting the stability and treatment capacity of the biological treatment system, making it difficult for the treated rainwater to meet reuse standards, and hindering the full utilization of biological treatment, thereby reducing the efficiency of pollutant removal and rainwater purification.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a rainwater recycling biological treatment oxygenation component, comprising a water storage shell, an oxygenation mechanism rotatably connected to the top of the inner side of the water storage shell, and a circulation mechanism fixedly connected to both sides of the water storage shell.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A rainwater harvesting biological treatment oxygenation component includes a water storage shell 1, an oxygenation mechanism 2 rotatably connected to the top of the inner side of the water storage shell 1, and a circulation mechanism 3 fixedly connected to both sides of the water storage shell 1.

[0029] The oxygenation mechanism 2 includes a reduction motor 21, a connecting rod 22, three sets of oxygen supply cylinders 23, an air inlet 24, and a rotating shaft 25. The reduction motor 21 is fixedly connected to the top of the rear side of the water storage tank 1. The connecting rod 22 is rotatably connected to the top of the inner side of the water storage tank 1. The oxygen supply cylinders 23 are fixedly connected to the surface of the connecting rod 22. The air inlet 24 is opened at the top and bottom of the oxygen supply cylinders 23. The rotating shaft 25 is fixedly connected to the top of the front side of the water storage tank 1. The front side of the rotating shaft 25 is rotatably connected to the inner side of the rotating shaft 25.

[0030] In this embodiment: the water storage shell 1 provides installation space and support for the oxygenation mechanism 2 and the circulation mechanism 3, and can store rainwater to be treated, allowing the rainwater to undergo a series of operations such as oxygenation and biological treatment. The geared motor 21 enables the connecting rod 22 to rotate at a suitable speed through deceleration, ensuring the oxygenation effect while avoiding unnecessary impact on the water and equipment due to excessive speed, and stably driving the subsequent components to perform oxygenation work. The connecting rod 22 transmits the power of the geared motor 21 to the oxygen supply cylinder 23, allowing water from the inside of the water storage shell 1 to smoothly enter the oxygen supply cylinder 23, while the air inlet 24 at the top allows air to enter. The efficient entry of air and water allows for full contact, greatly increasing the chances of oxygen dissolving in the water. This enables oxygen to integrate into the water more quickly and fully, effectively increasing the dissolved oxygen content and providing sufficient oxygen for the growth and metabolism of microorganisms in the subsequent biological treatment process. The air inlet 24 allows air to smoothly enter the water during the rotation of the oxygen supply cylinder 23, optimizing the contact path between air and water and improving the efficiency of air entering the water, thereby enhancing the oxygenation effect. The rotating shaft 25 provides a rotation support point at the front end of the connecting rod 22, and together with the connection structure at the rear top of the water storage shell 1, it ensures the stability and coaxiality of the rotation of the connecting rod 22.

[0031] Specifically, such as Figure 3As shown, the circulation mechanism 3 includes several inlet pipes 31, two inlet shells 32, a diversion pipe 33, a connecting pipe 34, a circulation pump 35, and a pumping pipe 36. The inlet pipes 31 are fixedly connected to both sides of the water storage shell 1.

[0032] Specifically, such as Figure 3 As shown, the water inlet shell 32 is fixedly connected to the top of the water inlet pipe 31, the diversion pipe 33 is fixedly connected to the front side of the water inlet shell 32, the connecting pipe 34 is fixedly connected to the bottom of the front side of the diversion pipe 33, and the circulation pump 35 is fixedly connected to the bottom of the front side of the water storage shell 1.

[0033] Specifically, such as Figure 3 As shown, the bottom of the connecting pipe 34 is fixedly connected to the front side of the circulating pump 35, the pumping pipe 36 is fixedly connected to the rear side of the circulating pump 35, and the rear side of the pumping pipe 36 is fixedly connected to the bottom of the front side of the water storage shell 1. The water storage shell 1, the inlet pipe 31, the inlet shell 32, the diversion pipe 33, the connecting pipe 34, the circulating pump 35 and the pumping pipe 36 are connected.

[0034] In this embodiment: the inlet pipe 31 can support and limit the inlet shell 32, and can guide the rainwater inside the inlet shell 32 to the inside of the water storage shell 1. The inlet shell 32 can collect rainwater. The diversion pipe 33 can guide the rainwater guided by the connecting pipe 34 back into the inside of the inlet shell 32. The connecting pipe 34 can guide the rainwater drawn by the circulation pump 35 to the diversion pipe 33. The circulation pump 35 provides power for the circulation of water. By drawing and transporting water, the water in the water storage shell 1 can continuously circulate, promoting full contact between pollutants and microorganisms in the water. The pumping pipe 36 can allow the circulation pump 35 to draw out the rainwater inside the water storage shell 1.

[0035] Specifically, such as Figure 4 As shown, a filter screen 4 is fixedly connected to the inner side of the air inlet 24, and the surface of the filter screen 4 is coated with an anti-corrosion coating.

[0036] Specifically, such as Figure 4 As shown, a filter plate 5 is fixedly connected to the top of the water inlet shell 32, and the filter plate 5 is triangular.

[0037] In this embodiment: by setting a filter screen 4, when air enters the oxygen supply cylinder 23 through the top air inlet 24, the filter screen 4 can intercept dust, impurities and other particulate matter in the air, preventing these substances from entering the interior of the oxygen supply cylinder 23. By setting an anti-corrosion coating, it can effectively resist the erosion of the filter screen 4 by corrosive substances such as acids and alkalis in rainwater and the humid environment, extending the service life of the filter screen 4. By setting a filter plate 5, rainwater entering the water inlet shell 32 can be filtered to prevent leaves, branches or other impurities from entering the inside of the water inlet shell 32. By setting the filter plate 5 in a triangular shape, the accumulation of impurities on the filter plate 5 is reduced, making it easier to clean and maintain.

[0038] Specifically, such as Figure 5 As shown, a sealing ring 6 is fixedly connected to the side of the water inlet pipe 31 near the water storage shell 1, and the side of the sealing ring 6 away from the water inlet pipe 31 is fixedly connected to the surface of the water storage shell 1.

[0039] Specifically, such as Figure 5 As shown, a reinforcing base 7 is fixedly connected to the bottom of the circulating pump 35, and the surface of the reinforcing base 7 is coated with an anti-corrosion coating.

[0040] In this embodiment: by setting a sealing ring 6, it is possible to effectively prevent rainwater in the water storage tank 1 from leaking from the connection between the water inlet pipe 31 and the water storage tank 1 during the circulation process. By setting a reinforcing seat 7, additional support and stability are provided for the circulation pump 35. By setting an anti-corrosion coating, the reinforcing seat 7 can be protected from corrosion by rainwater and humid environments.

[0041] Working Principle: First, the user moves the water storage tank 1 to the desired working position. When it rains, the rainwater first comes into contact with the filter plate 5. Due to the presence of the filter plate 5, larger particles and floating objects in the rainwater are effectively intercepted, preventing these substances from entering the water inlet tank 32. After preliminary filtration, the rainwater falls smoothly into the inner side of the water inlet tank 32. Then, by gravity and water flow, the rainwater flows into the inner side of the water storage tank 1 through the water inlet pipe 31. At this time, the water storage tank 1 begins to store rainwater to be treated. In order to oxygenate the rainwater, the user turns on the power and starts the reduction motor 21. The reduction motor 21 starts to run, driving the connecting rod 22 to rotate at a slow and stable speed. The connecting rod 22, as a transmission component, will synchronously drive the three sets of oxygen supply cylinders 23 fixed on its surface to rotate during the rotation. As the oxygen supply cylinders 23 rotate, the rainwater will enter the inner side of the oxygen supply cylinders 23 through the air inlet 24 at the bottom, while the air will enter through the top of the oxygen supply cylinders 23 with the help of the rotation of the oxygen supply cylinders 23. As the oxygen supply cylinder 23 rotates continuously, when the top air inlet 24 rotates to the bottom position, the rainwater inside the oxygen supply cylinder 23, which is in full contact with air and rich in dissolved oxygen, will efficiently replace the rainwater inside the water storage shell 1. This replacement process not only significantly increases the dissolved oxygen content of the rainwater in the water storage shell 1, but also promotes water mixing, making oxygen more evenly distributed throughout the water body, providing good conditions for subsequent biological treatment. At the same time, the user powers on and starts the circulation pump 35, which begins to work, continuously drawing rainwater from the inside of the water storage shell 1 through the water pumping pipe 36. The drawn rainwater is guided by the connecting pipe 34 and transported to the diversion pipe 33. The diversion pipe 33 can evenly guide the rainwater to the inside of the two water inlet shells 32. In this way, the rainwater forms a continuous circulation flow, allowing the pollutants in the rainwater to come into more full contact with microorganisms, greatly improving the efficiency and effect of biological treatment.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
