Description

Technical Field

[0001] This application relates to the field of greywater reuse, and in particular to a greywater reuse permeation filtration device. Background Technology

[0002] Wastewater reuse technology involves the centralized treatment of wastewater to meet certain standards before reuse, thereby achieving water conservation. This is of great significance given the current increasingly strained water resources. Wastewater reuse filtration systems in power plants often employ variable porosity filters, designed as forward-flow deep-bed filters based on the "co-current coagulation" theory.

[0003] In the process of reclaimed water reuse, the filtration stage is crucial. Existing reclaimed water filtration devices generate significant impact force from the water discharged through the pipes during operation. When this water flow impacts the filter screen, it can cause damage, reducing the filter's lifespan and increasing maintenance costs. Furthermore, the high flow rate of the water impacting the filter screen means that some impurities may not have enough time to be fully intercepted, negatively affecting the filtration effect and making it difficult to achieve the desired purification level of the reclaimed water. This, in turn, impacts the overall quality and application scope of reclaimed water reuse.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a defect in the process of reclaimed water reuse where water flow impacts the filter screen, affecting the filtration effect. Therefore, they have proposed a reclaimed water reuse infiltration filtration device to solve the above problems. Utility Model Content

[0005] To address the problem of water flow impacting the filter screen and affecting the filtration effect during the reuse of greywater, this application provides a greywater reuse infiltration filtration device.

[0006] The technical solution of the greywater reuse permeation filtration device provided in this application is as follows:

[0007] A reclaimed water infiltration filtration device includes a filtration unit. A fixed inner cavity is formed at the top center of the filtration unit. Several filter screens are arranged side-by-side inside the fixed inner cavity. A buffer frame is installed at the top center of the filtration unit. Several drainage holes are formed at the bottom of the inner wall of the buffer frame. A fixed bracket is fixedly installed on the top of one side of the inner wall of the buffer frame. A collection hopper is fixedly installed at the top center of the fixed bracket. Several fixing holes are formed on both sides of the outer surface of the collection hopper. A wide-angle mask is integrally formed on the upper surface of the collection hopper. A stirring mechanism is also provided inside the buffer frame to control the water flow state within the buffer frame.

[0008] Preferably, the stirring mechanism includes a drive motor, which is located in the middle of the fixed frame. The output end of the drive motor extends to the bottom of the fixed frame and is fitted with a connecting shaft. Several water-dispelling plates are welded to the outer surface of the connecting shaft.

[0009] Preferably, a support frame is fixedly installed on the outer surface of the filter device above the buffer frame, and a water inlet pipe is fixedly connected inside the support frame, with the water inlet pipe located directly above the collection hopper.

[0010] Preferably, a support plate is fixedly installed on the top of the inner wall of the filter device, and the bottom edge of the buffer frame overlaps the upper surface of the support plate.

[0011] Preferably, the number of water-repelling plates is four, the overall length of the water-repelling plates is less than the inner wall radius of the buffer frame, and the buffer frame and the water-repelling plates are interlocked.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By incorporating a buffer frame, collection hopper, and stirring mechanism, when greywater flows in from the inlet pipe, it first passes through a wide-mouthed screen into the collection hopper. The water flow impacts the collection hopper, dispersing and buffering the impact force. Simultaneously, the drive motor in the stirring mechanism rotates the connecting shaft and the water-dispensing plate, stirring the water flow within the buffer frame. This allows the water to flow more smoothly and slowly through the drain holes into the filter screen below, effectively reducing the impact force of the water flow on the filter screen, preventing damage caused by water flow impact, extending the filter screen's lifespan, and reducing equipment maintenance costs. Moreover, the stable water flow allows impurities to fully settle and be intercepted on the filter screen, improving the filter screen's filtration effect, enhancing the purification level of the greywater, and ensuring the overall quality and application scope of greywater reuse.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a reclaimed water infiltration device. (Refer to...) Figure 1-3A reclaimed water infiltration filtration device includes a filter device 1. A fixed inner cavity 2 is formed at the center of the top of the filter device 1. Several filter screens 3 are arranged vertically inside the fixed inner cavity 2 for filtering reclaimed water. A support frame 4 is fixedly installed on the outer surface of the filter device 1 above a buffer frame 6. An inlet pipe 5 is fixedly connected inside the support frame 4. The inlet pipe 5 is fixed to the outer surface of the filter device 1 via the support frame 4 and is located above the buffer frame 6. Reclaimed water flows in through the inlet pipe 5, passes through a wide-mouth mask 11, and enters a collection hopper 9. The inlet pipe 5 is located directly above the collection hopper 9. The buffer frame 6 is installed at the center of the top of the filter device 1, and the drainage holes 7 at the bottom of its inner wall allow water to flow through and enter the filter screens 3 below. A support plate is fixedly installed on the top of the inner wall of the filter device 1. The bottom edge of the buffer frame 6 overlaps the upper surface of the support plate. Several drainage holes 7 are opened at the bottom of the inner wall of the buffer frame 6. A fixing frame 8 is fixedly installed on the top of one side of the inner wall of the buffer frame 6. A collection hopper 9 is fixedly installed at the middle of the top of the fixing frame 8. Several fixing holes 10 are opened on both sides of the outer surface of the collection hopper 9. The fixing frame 8 is used to fix the collection hopper 9. The fixing holes 10 on the outer surface of the collection hopper 9 can help fix related components. The wide mask 11 above it can expand the water flow receiving area and disperse the water flow impact force. The wide mask 11 is integrally formed on the upper surface of the collection hopper 9. The buffer frame 6 is also equipped with a stirring mechanism to control the water flow state in the buffer frame 6.

[0020] Reference Figure 2 and Figure 3 The stirring mechanism includes a drive motor 12, which is located in the middle of the fixed frame 8. The output end of the drive motor 12 extends to the bottom of the fixed frame 8 and is equipped with a connecting shaft 13. Several water-dispelling plates 14 are welded to the outer surface of the connecting shaft 13. There are four water-dispelling plates 14. The overall length of the water-dispelling plates 14 is less than the inner radius of the buffer frame 6. The buffer frame 6 and the water-dispelling plates 14 are interlocked.

[0021] The drive motor 12 is positioned in the middle of the fixed frame 8. When the drive motor 12 is working, it drives the connecting shaft 13 to rotate. The water-dispelling plate 14 on the outer surface of the connecting shaft 13 rotates accordingly, stirring the water flow in the buffer frame 6 and making the water flow smoothly through the drain hole 7.

[0022] The implementation principle of the greywater reuse permeation filtration device in this embodiment is as follows: When greywater needs filtration, water flows out from the inlet pipe 5, passes through the wide-mouth filter 11, and enters the collection hopper 9. During this process, the impact force of the water flow is initially dispersed. Subsequently, the drive motor 12 starts, driving the connecting shaft 13 and the water-dispersing plate 14 to rotate, stirring the water flow in the buffer frame 6, making the water flow smooth and slow. The smooth water flow passes through the drain hole 7 at the bottom of the inner wall of the buffer frame 6, enters the fixed inner cavity 2, and then passes through the filter screens 3 arranged in parallel. During this process, impurities are fully intercepted by the filter screens 3, achieving effective filtration of greywater. Through this structural design and workflow, the impact of water flow on the filter screen is effectively reduced, the filtration effect is improved, and the quality of greywater reuse is guaranteed.
