Description

Technical Field

[0001] This utility model belongs to the field of greywater reuse technology, specifically a greywater reuse device. Background Technology

[0002] Greywater reuse technology has received widespread attention as an effective means of water resource recycling. Greywater reuse devices are mainly used to treat domestic sewage or industrial wastewater, purifying it to water quality standards that can be reused. They are widely used in urban greening, road spraying, industrial cooling and other fields. However, traditional greywater reuse devices have some shortcomings in practical applications.

[0003] Traditional greywater reuse systems typically include treatment stages such as sedimentation, filtration, and aeration. However, these stages are often set up independently and lack effective coordination. For example, when the settled water is transported to the filtration chamber, the complex connections between the various treatment units can easily cause interruptions or backflows in the water flow between different stages. This uneven water flow not only affects the stability of the filtration effect but may also lead to low equipment operating efficiency and increased processing time. Furthermore, the lack of coordination between the various treatment stages makes it difficult for the entire greywater treatment process to achieve the ideal state of efficient and stable operation, failing to meet the urgent needs of rapid greywater treatment and timely reuse in practical applications. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a greywater reuse device, which solves the problem that the traditional greywater reuse process is often set up independently. Due to the complex connection between each treatment unit, the water flow is prone to interruption or backflow when flowing between different stages. This uneven water flow not only affects the stability of the filtration effect, but may also lead to low equipment operating efficiency and increased processing time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a greywater reuse device, comprising a sedimentation tank, a filter tank on one side of the sedimentation tank, an aeration tank on one side of the filter tank, a connecting rod between the sedimentation tank, the filter tank, and the aeration tank, the sedimentation tank, the filter tank, and the aeration tank being connected by the connecting rod, a filter plate fixedly installed near the bottom of the inner wall of the sedimentation tank, a rotating rod rotatably connected between the filter plate and the top of the sedimentation tank, a plurality of stirring rods fixedly connected to the outer wall of the rotating rod, a control motor fixedly installed at the top of the filter tank, the output end of the control motor being connected to the top of the rotating rod, a water inlet located near the side of the top of the filter tank, a first water supply pipe fixedly connected near the bottom of the sedimentation tank, a first suction pump located at the other end of the first water supply pipe, the first suction pump being fixedly installed at the top of the filter tank, and the other end of the first water supply pipe being connected to the center of the top of the filter tank.

[0006] As a further embodiment of this utility model: a fixed support is provided between the inner walls of the filter chamber, the fixed support is connected to the inner wall of the top of the filter chamber and is located below the first water supply pipe, and a filter assembly is provided between the inner walls of the fixed support, the filter assembly being arranged from top to bottom as anthracite, quartz sand, activated carbon and polypropylene fiber filter element.

[0007] As a further embodiment of this utility model: a second water supply pipe is fixedly connected to the bottom of the filter chamber, and a second suction pump is provided at the other end of the second water supply pipe. The second suction pump is fixedly installed at the top of the aeration chamber, and the other end of the second water supply pipe is connected to the center of the top of the aeration chamber.

[0008] As a further embodiment of this utility model: the aeration chamber is provided with an aeration pipe inside, the aeration pipe is fixedly connected to the inner wall of the aeration chamber, and a blower is fixedly installed on one side of the aeration chamber, the blower being connected to one end of the aeration pipe.

[0009] As a further embodiment of this utility model: a water outlet pipe is fixedly connected to one side of the aeration chamber near the bottom, and a water valve is provided above the water outlet pipe.

[0010] As a further embodiment of this utility model: two guide plates are symmetrically fixedly installed on the inner walls of the bottom of the sedimentation chamber, the filtration chamber and the aeration chamber, with the two guide plates facing each other; and four pillars are fixedly installed at the four corners of the bottom of the sedimentation chamber, the filtration chamber and the aeration chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This greywater reuse device, by setting up sedimentation tanks, filtration tanks, and aeration tanks, which are tightly connected by connecting rods, forms an organic integrated treatment system. This design makes the flow of greywater between each treatment stage smoother, avoiding water flow interruptions or backflow caused by complex connections between devices. From the initial filtration in the sedimentation tank to the deep purification in the filtration tank, and then to the biodegradation in the aeration tank, the entire treatment process is completed in one go, greatly improving the overall efficiency of greywater treatment. At the same time, the coordinated work between the tanks reduces the residence time of greywater in the treatment process, speeds up the treatment, and makes the operation of the entire greywater reuse device more efficient and stable, better meeting the needs of rapid greywater treatment and reuse in practical applications.

[0013] 2. This greywater reuse device, by incorporating filter plates and stirring rods, prevents sediment accumulation and agglomeration. The filter plates effectively intercept larger suspended solids and impurities, preventing these substances from entering subsequent filtration and aeration chambers, thereby reducing the load on subsequent treatment units. The stirring rods further prevent sediment from agglomerating above the filter plates, avoiding the impact of sludge accumulation on the sedimentation effect. This design not only improves the operating efficiency of the sedimentation chamber but also extends the service life of the filter plates, reduces maintenance costs, and ensures the long-term stable operation of the entire greywater reuse device.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-5As shown, this utility model provides a technical solution: a greywater reuse device, including a sedimentation tank 1, a filter tank 2 on one side of the sedimentation tank 1, and an aeration tank 3 on one side of the filter tank 2. A connecting rod 4 is provided between the sedimentation tank 1, the filter tank 2, and the aeration tank 3, and the sedimentation tank 1, the filter tank 2, and the aeration tank 3 are connected by the connecting rod 4. A filter plate 5 is fixedly installed on the inner wall of the sedimentation tank 1 near the bottom. Because of the filter plate 5, the filter plate 5 can effectively intercept larger suspended solids and impurities, preventing these substances from entering the subsequent filter tank 2 and aeration tank 3, thereby reducing the load on the subsequent treatment units. A rotating rod 6 is rotatably connected between the filter plate 5 and the top of the sedimentation tank 1. Several stirring rods 7 are fixedly connected to the outer wall of the rotating rod 6. A control motor 8 is fixedly installed on the top of the filter tank 2, and the output end of the control motor 8 is connected to... The top of the rotating rod 6 is connected to the stirring rod 7. Through the cooperation between the rotating rod 6 and the stirring rod 7, the rotating rod 6 rotates under the drive of the control motor 8, which drives the stirring rod 7 on its outer wall to rotate. This can stir the water in the sedimentation chamber 1, prevent the sediment from clumping above the filter plate 5, avoid the accumulation of sludge above the filter plate 5, which would affect the normal operation of the sedimentation chamber 1 and make the sedimentation effect worse. Through the stirring action of the stirring rod 7, the sediment can be kept loose, which is convenient for subsequent cleaning. The top of the filter chamber 2 is provided with a water inlet 9 near its side. The sedimentation chamber 1 is fixedly connected to the bottom of the first water supply pipe 10. The other end of the first water supply pipe 10 is provided with a first suction pump 11. The first suction pump 11 is fixedly installed at the top of the filter chamber 2. The other end of the first water supply pipe 10 is connected to the center of the top of the filter chamber 2.

[0022] A fixed support 12 is provided between the inner walls of the filter chamber 2. The fixed support 12 is connected to the inner wall of the top of the filter chamber 2 and is located below the first water supply pipe 10. A filter assembly 13 is provided between the inner walls of the fixed support 12. The filter assembly 13 is arranged from top to bottom as anthracite, quartz sand, activated carbon and polypropylene fiber filter element. A second water supply pipe 14 is fixedly connected near the bottom of the filter chamber 2. A second suction pump 15 is provided near the other end of the second water supply pipe 14. The second suction pump 15 is fixedly installed at the top of the aeration chamber 3. The other end of the second water supply pipe 14 is connected to the center of the top of the aeration chamber 3. The filtered water is transported to the aeration chamber 3 through the second water supply pipe 14 and under the action of the second suction pump 15. The cooperation of the second water supply pipe 14 and the second suction pump 15 can ensure that the filtered water can be stably transported from the filter chamber 2 to the aeration chamber 3, providing a stable water flow to the aeration chamber 3 and avoiding uneven aeration and obstruction of aerobic microbial growth and metabolism due to unstable water flow.

[0023] The aeration chamber 3 is equipped with an aeration pipe 16, which is fixedly connected to the inner wall of the aeration chamber 3. A blower 17 is fixedly installed on one side of the aeration chamber 3, and the blower 17 is connected to one end of the aeration pipe 16. The blower 17 injects air evenly into the water entering the aeration chamber 3 through the aeration pipe 16, increasing the dissolved oxygen content in the water. The uniform water flow and aeration method enable aerobic microorganisms to obtain sufficient oxygen, promoting their growth and metabolism, thereby more effectively degrading organic matter in wastewater and improving the treatment effect of reclaimed water. An outlet pipe 1 is fixedly connected to one side of the aeration chamber 3 near the bottom. 8. A water valve 19 is provided above the outlet pipe 18. Two guide plates 20 are symmetrically fixedly installed on the inner walls of the bottom of the sedimentation tank 1, the filter tank 2, and the aeration tank 3. The guide plates 20 can guide the direction of water flow, so that the water flows in the sedimentation tank 1, the filter tank 2, and the aeration tank 3 according to a predetermined path, avoiding the generation of eddies or turbulence at the bottom of the water flow, and can also allow the water flow in the sedimentation tank 1, the filter tank 2, or the aeration tank 3 to flow to the next treatment stage. The two guide plates 20 are oriented opposite each other. Four pillars 21 are fixedly installed at the four corners of the bottom of the sedimentation tank 1, the filter tank 2, and the aeration tank 3.

[0024] The working principle of this utility model is as follows: First, greywater enters the sedimentation chamber 1 through the water inlet 9, and then undergoes preliminary filtration through the filter plate 5 fixed near the bottom of the inner wall of the sedimentation chamber 1 to remove larger suspended particles and impurities. The rotating rod 6 inside the sedimentation chamber 1 rotates under the drive of the control motor 8, and the stirring rod 7 fixedly connected to the outer wall of the rotating rod 6 stirs the water in the sedimentation chamber 1. The settled clear water descends below the filter plate 5 and is transported to the filter chamber 2 through the first water supply pipe 10 under the action of the first suction pump 11. In the filter chamber 2, the clear water from the sedimentation chamber 1 enters the filter chamber 2 and passes through the fixed support 12... The filter assembly 13 further filters the water, removing fine suspended particles and some dissolved organic matter to improve water quality. The filtered water is then transported to the aeration chamber 3 via the second water supply pipe 14 and the second suction pump 15. In the aeration chamber 3, the blower 17 injects air into the water through the aeration pipe 16 to increase the dissolved oxygen content. The aeration process provides the necessary oxygen for aerobic microorganisms to promote their growth and metabolism, thereby improving the degradation efficiency of organic matter in the wastewater. Finally, the effluent pipe 18 is used to discharge the treated wastewater, and the effluent flow rate is controlled by the water valve 19 above the effluent pipe 18.
