Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, specifically to a rainwater recycling device. Background Technology

[0002] The water demand in student dormitories is concentrated in non-potable water scenarios. Rainwater recycling devices can specifically meet these needs and integrate into students' daily lives. For example, rainwater from the dormitory roof can be collected and piped into a small sedimentation tank next to the dormitory to filter out dust, fallen leaves and other debris to prevent clogging of subsequent equipment. The stored rainwater can also be used to water the lawns and shrubs below the dormitory.

[0003] Current rainwater recycling systems are not effective enough in terms of purification. Some systems only use a basic process of bar screens and sedimentation tanks. Since rainwater adsorbs atmospheric pollutants when it falls, ordinary filters cannot completely purify it. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A rainwater recycling device, comprising:

[0006] A water storage tank is provided, with a drain pipe connected to one side of the water storage tank and a treatment tank connected to the top of the water storage tank. A lower frame is rotatably connected to the top of the treatment tank. A drive mechanism is provided on both the left and right sides of the bottom of the lower frame. Several first springs are connected to both sides of the top of the lower frame. An upper frame is connected to the top of the first springs. A vibration motor is connected to the bottom of the upper frame at the front side. A filter screen is connected to the inner side of the upper frame.

[0007] The front side of the processing box has a through hole, and an inner shell is slidably connected inside the through hole. A filter mechanism is installed inside the inner shell.

[0008] The front side of the processing box is connected to a pair of third hinge seats at the bottom of the through hole. A baffle is rotatably connected inside the third hinge seat. An insertion hole is opened at the top of the baffle, and a limit mechanism is provided inside the insertion hole.

[0009] In one possible implementation, the filtration mechanism includes three filter plates arranged sequentially from top to bottom, with a sand filter layer and an activated carbon layer respectively disposed on the inner side of each filter plate from top to bottom.

[0010] In one possible implementation, a bushing is connected to the front side of the lower frame, and a shaft is rotatably connected inside the bushing, with both ends of the shaft being fixedly connected to the processing box.

[0011] In one possible implementation, the drive mechanism includes an electric push rod, the output end of which is rotatably connected to a first hinge seat. The top of the first hinge seat is fixedly connected to a lower frame, and the bottom of the electric push rod is rotatably connected to a second hinge seat. The bottom of the second hinge seat is connected to a support frame, and the bottom of the support frame is fixedly connected to a water storage tank.

[0012] In one possible implementation, the limiting mechanism includes a U-shaped shell with a pair of elongated holes on the front side. An L-shaped insert is slidably connected inside the elongated holes, with one end of the L-shaped insert extending into the interior of the insertion hole. A second spring is connected to the back side of the L-shaped insert, and a partition is connected to one end of the second spring. The partition is fixedly connected to the inner wall of the U-shaped shell.

[0013] In one possible implementation, a limiting strip is provided on the inner wall of the processing box at the bottom of the through hole, and the limiting strip is located below the inner shell.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By installing an upper frame at the top of the treatment box and a filter screen inside the upper frame, large particulate impurities such as fallen leaves mixed in during rainwater collection can be easily intercepted, preventing them from clogging the internal structure of the treatment box. Then, an inner shell is installed inside the treatment box. Inside the inner shell, three filter plates are installed from top to bottom. In the middle of the three filter plates, a sand filter layer and an activated carbon layer are installed from top to bottom. The sand filter layer utilizes the pores between particles to effectively trap suspended particulate matter, while the activated carbon has a porous structure that can adsorb dissolved organic pollutants in rainwater, greatly improving the filtration effect.

[0016] 2. By activating the electric push rod, the lower frame can be easily driven to flip. When the lower frame flips to the position where the filter screen is facing down, the vibration motor can be activated. The vibration motor uses high-frequency vibration to make the filter screen resonate, which helps to shake off the impurities trapped in the filter screen during the filtration process and prevent them from clogging the pores.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This application provides a rainwater recycling device to solve the problems in the prior art.

[0027] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0028] like Figures 1-5 As shown, a rainwater recycling device includes:

[0029] A water storage tank 6 is connected to a drain pipe 7 on one side. A treatment tank 8 is connected to the top of the water storage tank 6. A lower frame 3 is rotatably connected to the top of the treatment tank 8. A drive mechanism is provided on both the left and right sides of the bottom of the lower frame 3. Several first springs 16 are connected to both sides of the top of the lower frame 3. An upper frame 2 is connected to the top of the first springs 16. A vibration motor 27 is connected to the bottom of the upper frame 2 at the front side. A filter screen 1 is connected to the inside of the upper frame 2.

[0030] The front side of the processing box 8 is provided with a through hole 19, and an inner shell 10 is slidably connected inside the through hole 19. A filter mechanism is provided inside the inner shell 10.

[0031] A pair of third hinge seats 15 are connected to the bottom of the through hole 19 on the front side of the processing box 8. A baffle 9 is rotatably connected inside the third hinge seat 15. An insertion hole 28 is opened at the top of the baffle 9. A limit mechanism is provided inside the insertion hole 28.

[0032] In some examples, the filtration mechanism includes three filter plates 20 arranged from top to bottom. The inner sides of the three filter plates 20 are respectively provided with a sand filter layer 21 and an activated carbon layer 22 from top to bottom. The sand filter layer 21 utilizes the pores between particles to effectively trap suspended particulate matter at a deep depth. The activated carbon has a porous structure that can adsorb organic pollutants dissolved in rainwater, greatly improving the filtration effect.

[0033] In some examples, a bushing 13 is connected to the front side of the lower frame 3, and a shaft 17 is rotatably connected inside the bushing 13. Both ends of the shaft 17 are fixedly connected to the processing box 8, which facilitates the flexible rotation of the lower frame 3.

[0034] In some examples, the drive mechanism includes an electric push rod 4, the output end of which is rotatably connected to a first hinge seat 11. The top of the first hinge seat 11 is fixedly connected to the lower frame 3, and the bottom of the electric push rod 4 is rotatably connected to a second hinge seat 12. The bottom of the second hinge seat 12 is connected to a support frame 5, and the bottom of the support frame 5 is fixedly connected to a water storage tank 6. When the electric push rod 4 is turned on, it is convenient to drive the lower frame 3 to flip. When the lower frame 3 is flipped so that the filter screen 1 is facing down, the vibration motor 27 is turned on. The vibration motor 27 vibrates at high frequency, which can make the filter screen 1 resonate, which is beneficial to shake off the impurities trapped by the filter screen 1 during the filtration process.

[0035] In some examples, the limiting mechanism includes a U-shaped shell 14, with a pair of elongated holes 25 on the front side of the U-shaped shell 14. An L-shaped insert 26 is slidably connected inside the elongated holes 25. One end of the L-shaped insert 26 extends into the interior of the insertion hole 28. A second spring 24 is connected to the back side of the L-shaped insert 26. One end of the second spring 24 is connected to a partition 23. The partition 23 is fixedly connected to the inner wall of the U-shaped shell 14. Simultaneously pulling the L-shaped inserts 26 on both sides drives the L-shaped inserts 26 on both sides to move in opposite directions, making it convenient to remove the L-shaped inserts 26 on both sides from the interior of the insertion hole 28. Then, it is convenient to put down the baffles 9 on both sides, and then convenient to remove the inner shell 10.

[0036] In some examples, the inner wall of the processing box 8 is provided with a limiting strip 18 at the bottom of the through hole 19. The limiting strip 18 is located below the inner shell 10 to facilitate limiting the inner shell 10.

[0037] This invention features an upper frame 2 at the top of the treatment chamber 8, with a filter screen 1 installed inside the upper frame 2. This facilitates the interception of large particulate impurities, such as fallen leaves, mixed in during rainwater collection, preventing them from clogging the internal structure of the treatment chamber 8. An inner shell 10 is then installed inside the treatment chamber 8. Inside the inner shell 10, three filter plates 20 are arranged from top to bottom. A sand filter layer 21 and an activated carbon layer 22 are respectively installed in the middle of the three filter plates 20 from top to bottom. The sand filter layer 21 utilizes the pores between particles to effectively trap suspended particulate matter, while the activated carbon, with its porous structure, adsorbs dissolved organic pollutants from rainwater, significantly improving the filtration effect. Furthermore, when needed... When cleaning the filter screen 1, the electric push rod 4 is turned on to drive the lower frame 3 to flip over. When the lower frame 3 is flipped so that the filter screen 1 is facing down, the vibration motor 27 is turned on. The vibration motor 27 vibrates at high frequency, which makes the filter screen 1 resonate. This helps to shake off the impurities trapped in the filter screen 1 during the filtration process and prevents them from clogging the pores. In addition, when it is necessary to clean the sand filter layer 21 and activated carbon layer 22 inside the inner shell 10, the L-shaped inserts 26 on both sides can be driven to move in opposite directions. This makes it easy to remove the L-shaped inserts 26 from the inside of the insertion hole 28, and then it is easy to put down the baffles 9 on both sides, and then it is easy to remove the inner shell 10.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
