Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and in particular relates to a rainwater filtration and recycling device for roads in sponge city construction. Background Technology

[0002] Rainwater filtration refers to the process of removing pollutants (such as suspended solids, organic matter, heavy metals, and grease) that are mixed into rainwater during its collection and transmission through physical interception, adsorption, and biodegradation technologies, so that the rainwater quality meets the "reuse standard" (such as greening irrigation and road washing) or the "discharge / recharge standard" (such as discharge into natural water bodies and replenishment of groundwater).

[0003] Chinese patent CN219973361U discloses a rainwater harvesting and filtration system, including a collection device, a sedimentation device, a filtration device, a sludge removal device, and a water storage device. By setting up the above-mentioned rainwater harvesting and filtration system, rainwater can be collected and subjected to multiple sedimentation and filtration processes to obtain cleaner rainwater, thus realizing the recycling of rainwater. By setting up a sedimentation device with a first sedimentation element and a first water storage element, rainwater can be sedimented after entering the first sedimentation element. After sedimentation, the rainwater enters the first water storage element for further sedimentation. After further sedimentation, the rainwater enters the filtration device for filtration. Rainwater can be sedimented multiple times to obtain cleaner rainwater, meeting the needs of high-quality rainwater filtration and realizing the recycling of rainwater.

[0004] As shown above, when this device filters rainwater, it is unclear how its internal filter elements filter the rainwater, and it may be difficult to effectively filter out oil, heavy metals, and microorganisms contained in the rainwater. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a rainwater filtration and recycling device for roads used in sponge city construction, which solves the problem of difficulty in filtering oil, heavy metals, and microorganisms from rainwater.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a rainwater filtration and recycling device for roads in sponge city construction, including a water storage tank, a circulation mechanism on the top of the water storage tank for recycling the filtered rainwater, and a filtration mechanism on the top of the water storage tank for filtering various harmful substances in the rainwater.

[0007] The circulation mechanism includes an inlet tank fixed to the top of a storage tank. A filter box is fixedly connected to the top of the storage tank, and a debris removal box is fixedly connected to the top of the filter box. A suction pipe is fixedly connected to the inner wall of the inlet tank. A water pump is fixedly connected to the end of the suction pipe away from the inlet tank. An outlet pipe is fixedly connected to the output end of the water pump. A limit frame is fixedly connected to the outer wall of the storage tank. A baffle plate is slidably connected to the inner wall of the limit frame. An inclined plate is fixedly connected to the inner wall of the inlet tank.

[0008] Preferably, the filtration mechanism includes a contact plate fixed to the inner wall of the filter box, a layer of ceramsite fixedly connected to the top of the contact plate, a layer of zeolite fixedly connected to the top of the ceramsite layer, a layer of activated carbon fixedly connected to the top of the zeolite layer, a water supply pipe fixedly connected to the bottom of the impurity removal box, a water-blocking ball rotatably connected to the inner wall of the water supply pipe, a rotating rod fixedly connected to the outer surface of the water-blocking ball, and a handle fixedly connected to the outer wall of the rotating rod.

[0009] Preferably, the inner wall of the debris removal box is provided with a cleaning mechanism for cleaning debris. The cleaning mechanism includes a movable frame that slides on the inner wall of the debris removal box. A debris removal plate is fixedly connected to the inner wall of the movable frame. Several toothed grooves are opened on the inner wall of the movable frame. A fixing frame is fixedly connected to the outer wall of the debris removal box.

[0010] Preferably, a central rod is rotatably connected to the inner wall of the fixed frame, a gear is fixedly connected to the outer surface of the central rod, a rotating frame is fixedly connected to the outer wall of the impurity removal box, and the outer surface of the gear meshes with the inner wall of the tooth groove.

[0011] Preferably, a worm gear is fixedly connected to the outer wall of the central rod, a worm is rotatably connected to the inner wall of the rotating frame, the outer surface of the worm meshes with the outer surface of the worm gear, and a handle is fixedly connected to the outer wall of the worm.

[0012] Preferably, the outer surface of the rotating rod is rotatably connected to the inner wall of the water supply pipe, and the outer wall of the rotating rod penetrates the inner wall of the water supply pipe and extends to the outside of the filter box.

[0013] This utility model has the following beneficial effects:

[0014] 1. This rainwater filtration and recycling device for sponge city construction roads works by pouring the rainwater to be treated into the inlet tank. Starting the water pump draws out the untreated rainwater from the inlet tank through the suction pipe, and then the rainwater is fed into the impurity removal box through the outlet pipe fixed to the pump's output end. Turning the handle rotates the rotating rod, which in turn rotates the water-blocking ball. Aligning the hole in the water-blocking ball with its bottom, the rainwater flows from the impurity removal box into the filter box. As the rainwater passes through the activated carbon layer, it adsorbs substances such as oil, pesticide residues, odors, and color. As it passes through the zeolite layer, it adsorbs heavy metals. As it passes through the ceramsite layer, it adsorbs pollutants and attached microorganisms, degrading organic matter and nitrogen and phosphorus. The filtered water then enters the storage tank through the contact plate, storing the filtered rainwater. When needed, the barrier plate is pulled out from the limiting frame. The advantage is that it deeply filters the rainwater, allowing for its storage.

[0015] 2. The rainwater filtration and recycling device for the sponge city construction road uses a rotating handle to drive a worm gear. When the worm gear rotates, the worm wheel also rotates, and the central rod also rotates. When the central rod rotates, the gear also rotates. Because the gear meshes with the toothed grooves inside the moving frame, the rotation of the gear drives the moving frame to move. At this time, the debris removal plate also moves out, thereby cleaning the leaves and other debris removed from it. The advantage is that it is easy to remove the debris removal plate to clean the filtered leaves and other debris, preventing too much debris from affecting the effect of subsequent deep filtration.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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.

[0026] This utility model provides two technical solutions:

[0027] Figures 1-3 The first embodiment is shown: a rainwater filtration and recycling device for roads in sponge city construction, including a water storage tank 1, a circulation mechanism on the top of the water storage tank 1 for recycling the filtered rainwater, and a filtration mechanism on the top of the water storage tank 1 for filtering various harmful substances in the rainwater.

[0028] The circulation mechanism includes an inlet tank 2, which is fixed to the top of the storage tank 1. A filter box 3 is fixedly connected to the top of the storage tank 1. A cleaning box 4 is fixedly connected to the top of the filter box 3. A suction pipe 5 is fixedly connected to the inner wall of the inlet tank 2. A water pump 6 is fixedly connected to the end of the suction pipe 5 away from the inlet tank 2. A water outlet pipe 7 is fixedly connected to the output end of the water pump 6. A limit frame 8 is fixedly connected to the outer wall of the storage tank 1. A baffle plate 9 is slidably connected to the inner wall of the limit frame 8. An inclined plate 10 is fixedly connected to the inner wall of the inlet tank 2.

[0029] The filtration mechanism includes a contact plate 11, which is fixed to the inner wall of the filter box 3. A ceramic particle layer 12 is fixedly connected to the top of the contact plate 11. A zeolite layer 13 is fixedly connected to the top of the ceramic particle layer 12. An activated carbon layer 14 is fixedly connected to the top of the zeolite layer 13. A water supply pipe 15 is fixedly connected to the bottom of the filter box 3. A water blocking ball 16 is rotatably connected to the inner wall of the water supply pipe 15. A rotating rod 17 is fixedly connected to the outer surface of the water blocking ball 16. A handle 18 is fixedly connected to the outer wall of the rotating rod 17.

[0030] By pouring the rainwater to be treated into the inlet tank 2, the water pump 6 is started. The pump draws out the untreated rainwater from the inlet tank 2 through the suction pipe 5, and then the rainwater is fed into the impurity removal box 4 through the outlet pipe 7 fixed to the output end of the pump 6. At this time, turning the handle 18 causes the rotating rod 17 fixed to its outer wall to rotate. When the rotating rod 17 rotates, the water-blocking ball 16 fixed to its outer wall also rotates. Aligning the opening of the water-blocking ball 16 with its bottom, rainwater will flow from the impurity removal box. Rainwater flows into the filter box 3 from the inside of the box 4. When the rainwater passes through the activated carbon layer 14, it will adsorb substances such as oil, pesticide residues, odors, and color. When the rainwater passes through the zeolite layer 13, it will adsorb heavy metal components in the rainwater. When the rainwater passes through the ceramsite layer 12, it will adsorb pollutants and attached microorganisms, degrading organic matter and nitrogen and phosphorus. At this time, the filtered water enters the water storage tank 1 through the contact plate 11, thereby storing the filtered rainwater. When it is needed, the barrier plate 9 can be pulled out from the limit frame 8.

[0031] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that the inner wall of the impurity removal box 4 is provided with a cleaning mechanism for cleaning impurities. The cleaning mechanism includes a movable frame 19 that slides on the inner wall of the impurity removal box 4. The inner wall of the movable frame 19 is fixedly connected to a impurity removal plate 20. The inner wall of the movable frame 19 is provided with a plurality of toothed grooves 25. The outer wall of the impurity removal box 4 is fixedly connected to a fixed frame 21. The inner wall of the fixed frame 21 is rotatably connected to a central rod 22. The outer surface of the central rod 22 is fixedly connected to a gear 23. The outer wall of the impurity removal box 4 is fixedly connected to a rotating frame 24. The outer surface of the gear 23 meshes with the inner wall of the toothed grooves 25. The outer wall of the central rod 22 is fixedly connected to a worm gear 26. The inner wall of the rotating frame 24 is rotatably connected to a worm 27. The outer surface of the worm 27 meshes with the outer surface of the worm gear 26. The outer wall of the worm 27 is fixedly connected to a handle 28.

[0032] The outer surface of the rotating rod 17 is rotatably connected to the inner wall of the water supply pipe 15, and the outer wall of the rotating rod 17 penetrates the inner wall of the water supply pipe 15 and extends to the outside of the filter box 3.

[0033] By rotating the handle 28, the worm 27 fixed on its outer wall is driven to rotate. When the worm 27 rotates, the worm wheel 26 meshing on its outer surface will also rotate. At this time, the central rod 22 fixed on the outer wall of the worm wheel 26 will also rotate. When the central rod 22 rotates, the gear 23 fixed on its outer surface will also rotate. Since the gear 23 meshes with the tooth groove 25 opened inside the moving frame 19, when the gear 23 rotates, it will drive the moving frame 19 to move. At this time, the debris removal plate 20 fixed inside the moving frame 19 will also move out, thereby cleaning the leaves and other debris removed from it.

[0034] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical component are not specifically limited; conventional equipment can be used.
