Description

Technical Field

[0001] The present invention belongs to the technical field of rainwater purification, and specifically relates to an initial rainwater ecological purification device. Background Art

[0002] The initial rainwater purification device is used to collect and preliminarily purify the initial rainwater, intercept large pollutants such as cigarette butts and leaves, reduce the pollutants in the rainwater, and reduce the pollution to the urban drainage system and the receiving water body. It is mainly applied to both sides of roads such as urban primary and secondary roads and branch roads in the city, leisure squares, traffic squares, etc. After the rainwater is purified, it can be recycled and stored for irrigation, road surface cleaning, etc.

[0003] Chinese Patent CN218421503U discloses an initial rainwater storage and purification device, including a cut-off well, an interception chamber, and a purification chamber. An overflow wall is provided in the cut-off well, and the inner cavity of the cut-off well is divided into two areas by the overflow wall. One area is connected to the rainwater pipe network through an overflow pipe, and a rainwater inlet is provided at the upper part of the other area, and the bottom is connected to the interception chamber through a float ball and a valve. The interception chamber is connected to the purification chamber through a grille. A light filter material layer is provided in the purification chamber, and a drain outlet is provided at the bottom of the purification chamber.

[0004] The above patent has the following deficiencies: When in use, it mainly preliminarily filters the debris in the rainwater through the grille. However, when the rainwater volume is large, the rainwater will carry a large amount of impurities such as leaves, dead branches, and domestic garbage into the device. When the mesh holes on the grille are blocked, it will seriously affect the flow of rainwater in the device. Although the rainwater will flow over the cut-off wall and into the rainwater pipe network, the rainwater also carries garbage impurities into the pipe network, which will block the pipe network. No matter how the rainwater flows in the device, the garbage impurities carried in from the ground will remain in the device, and it is inconvenient to clean, affecting the sustainable use effect of the device. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an initial rainwater ecological purification device, which can automatically remove the impurities intercepted on the filter screen and use the rainwater to automatically backwash the filter screen, so that the initial rainwater ecological purification device can operate continuously for a long time.

[0006] To solve the above technical problems, the present invention is solved by the following technical solutions: An initial rainwater ecological purification device includes a filter cylinder. Water inlets and sewage outlets are arranged on two opposite sides of the filter cylinder. A cylindrical rolling cylinder driven by a first motor is rotatably arranged in the filter cylinder. Mounting openings are oppositely arranged on the rolling cylinder. The mounting openings are concave towards the center of the rolling cylinder. Filter meshes are arranged in the mounting openings in a matching manner. A miscellaneous storage space is formed between the filter meshes and the filter cylinder. A water receiving tray is arranged inside the rolling cylinder on the inner side of the filter meshes. A water storage bladder is arranged at the bottom of the water receiving tray. A one-way water inlet pipe communicating with the water storage bladder and several one-way water outlet nozzles communicating with the water storage bladder are arranged on the water receiving tray. A water receiving trough for receiving rainwater falling from the water receiving tray is arranged in the filter cylinder. The water receiving trough is connected to a water storage tank. An elastic extrusion assembly is fixedly arranged in the filter cylinder. The elastic extrusion assembly includes a horizontally arranged fixed rod. A sliding rod is radially penetrated through the fixed rod. An extrusion block is connected to the bottom of the sliding rod. A return spring is arranged between the extrusion block and the fixed rod. When the water storage bladder is rotated to the side close to the sewage outlet, the elastic extrusion assembly extrudes the water in the water storage bladder to backwash the filter mesh. When this initial rainwater ecological purification device is in use, rainwater and sundries enter from the water inlet. After being filtered by the filter mesh, the rainwater falls from the filter mesh, and the sundries remain in the miscellaneous storage space. The falling rainwater falls onto the water receiving tray. When the water storage bladder is not full, the rainwater enters the water storage bladder through the one-way water inlet pipe. After the water storage bladder is full, the rainwater overflows from the outer periphery of the water receiving tray and flows into the water receiving trough, and then flows into the water storage tank from the water receiving trough. After being used for a period of time, the rolling cylinder is driven by the first motor to rotate for filter mesh switching. The sundries in the miscellaneous storage space are taken to the sewage outlet and discharged from the sewage outlet along with the rotation of the rolling cylinder. When the filter mesh is rotated to the lower side, the extrusion block extrudes the water storage bladder, and the water in the water storage bladder is sprayed out from the one-way water outlet nozzles, thereby backwashing the filter mesh, so that small particle sundries on the filter mesh are removed, and thus the initial rainwater ecological purification device can operate continuously for a long time.

[0007] In the above technical solution, preferably, the water inlet is located at the top of the filter cylinder, and a grille is arranged outside the water inlet. This initial rainwater ecological purification device is generally installed below the ground. The grille is provided to improve safety and prevent people from stepping on and falling into the water inlet.

[0008] In the above technical solution, preferably, the extrusion block is arc-shaped. Bent guiding rods are arranged on both sides of the water receiving tray. The water receiving tray is fixedly connected to the rolling cylinder through the guiding rods. The extrusion block extrudes the water storage bladder under the guidance of the guiding rods. The guiding rods can be used for positioning the water receiving tray and guiding the extrusion block. When the rolling cylinder rotates, the guiding rods can cooperate with the extrusion block to compress and reset the return spring, making the rotation of the roller and the expansion and contraction of the elastic extrusion assembly smoother.

[0009] In the above technical solution, preferably, the sewage outlet is located at the bottom of the filter cylinder, and a cleaning box communicating with the sewage outlet is arranged below the filter cylinder.

The driving shaft is driven by a second motor fixed on the elastic frame. The elastic frame of this brushing mechanism is lifted and lowered to cooperate with the concave structure of the filter screen. The driving shaft is driven by the second motor to rotate, so that the brushing assembly can brush the surface of the filter screen. Combined with the backwashing water, the filter screen can be cleaned more thoroughly.

[0011] In the above technical solution, preferably, the brushing assembly includes an ear plate on the connecting bracket, a buffer rod slidably connected to the ear plate, a roller connected to one end of the buffer rod, a first spring located between the buffer rod and the ear plate, and a brush plate connected to the buffer rod. When brushing the filter screen, the roller will first contact the rolling cylinder and the filter screen. Under the action of the first spring, the elastic force between the roller and the filter screen can be adjusted adaptively, driving the position between the brush plate and the filter screen to be adjusted, avoiding excessive force between the brush plate and the filter screen or the rolling cylinder, which may cause damage to the filter screen or the rolling cylinder.

[0012] In the above technical solution, preferably, the elastic frame is composed of two vertical plates and a U-shaped bracket connecting the two vertical plates. A support flat plate is fixedly connected in the cleaning box, a guide rod is fixedly connected to the support flat plate, a driving slide plate is fixedly connected to the vertical plate, the driving slide plate is slidably connected with the guide rod, and a second spring is arranged between the driving slide plate and the support flat plate.

[0013] In the above technical solution, preferably, a touch rod is connected to the driving slide plate, a touch switch is arranged below the filter cylinder, one end of the touch rod is in movable contact with the sensing end of the touch switch, and the touch switch is electrically connected to the second motor. When the rolling cylinder rotates to align the filter screen with the sewage outlet, the elastic frame and the driving slide plate are lifted by the second spring. At this time, the touch rod contacts the touch switch, controlling the second motor to rotate for a period of time to brush the filter screen, making the control of the brushing mechanism more convenient.

[0014] In the above technical solution, preferably, a discharge trough box is provided at the bottom of the cleaning box. A first auger mechanism is arranged in the discharge trough box. The outlet of the first auger mechanism is connected to a collection box. The bottom of the collection box is connected to a water filtration tank. The water filtration tank is communicated through a water passing hole opened on the collection box. The water filtration tank is connected to the water storage tank through a pipeline. With this structure, the first auger mechanism can discharge the sundries and water in the cleaning box to the collection box. Then, the water filtration tank collects the rainwater for backwashing and discharges it to the water storage tank for recycling.

[0015] In the above technical solution, preferably, a second auger mechanism vertically penetrating the collection box is provided on the collection box. A sundry box is arranged at the top outlet side of the second auger mechanism. With this structure, the second auger mechanism can lift the sundries in the collection box to the sundry box, facilitating subsequent collection and cleaning of the sundries.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When this initial rainwater ecological purification device is in use, rainwater and sundries enter from the water inlet. After being filtered by the filter screen, the rainwater falls from the filter screen, while the sundries remain in the storage space for sundries. The fallen rainwater lands on the water receiving tray. When the water storage bladder is not full, the rainwater enters the water storage bladder through the one-way water inlet pipe. After the water storage bladder is full, the rainwater overflows from the outer periphery of the water receiving tray and flows into the water receiving trough, and then flows into the water storage tank from the water receiving trough. After using it for a period of time, the rolling cylinder is driven by the first motor to rotate for filter screen switching. The sundries in the storage space for sundries are carried to the sewage outlet and discharged from the sewage outlet as the rolling cylinder rotates. And when the filter screen is rotated to the lower part, the extrusion block squeezes the water storage bladder, and the water in the water storage bladder is sprayed out from the one-way water outlet nozzle, thereby performing backwashing on the filter screen, so that the small particle sundries on the filter screen are removed, enabling the initial rainwater ecological purification device to operate continuously for a long time.

[0027] The following further describes the present invention in detail in conjunction with the accompanying drawings and specific implementation manners: Refer to Figures 1 to 10, An initial rainwater ecological purification device, including a filter cylinder 1. The shape of the filter cylinder 1 is not limited. In this embodiment, it is cylindrical. Water inlets 2 and sewage outlets 3 are arranged on two opposite sides of the filter cylinder 1. Among them, the water inlet 2 is located at the top and the sewage outlet 3 is located at the bottom. A cylindrical rolling cylinder 5 driven by a first motor 4 is rotatably arranged in the filter cylinder 1. The first motor 4 is fixedly installed on the outer wall of one end of the filter cylinder 1. Mounting openings 6 are oppositely arranged on the rolling cylinder 5. The positions of the mounting openings 6 match those of the water inlet 2 and the sewage outlet 3. The mounting openings 6 are concave towards the center of the rolling cylinder 5. A filter screen 7 is fixedly installed in the mounting openings 6 in a matching manner. A miscellaneous storage space 8 is formed between the filter screen 7 and the filter cylinder 1. A water receiving tray 9 is arranged inside the rolling cylinder 5 on the inner side of the filter screen 7. A water storage bladder 10 is arranged at the bottom of the water receiving tray 9. A one-way water inlet pipe 11 communicating with the water storage bladder 10 and several one-way water outlet nozzles 12 communicating with the water storage bladder 10 are arranged on the water receiving tray 9. Both the one-way water inlet pipe 11 and the one-way water outlet nozzles 12 are realized through one-way valves. The water receiving tray 9 does not necessarily have to completely catch the rainwater falling from the filter screen. As long as the water caught by the water receiving tray 9 can be used to fill the water storage bladder 10. The one-way water outlet nozzles 12 do not need to completely and evenly cover the filter screen either. As long as the water sprayed by them can basically completely cover the filter screen. The spraying direction of the one-way water outlet nozzles 12 can be used to ensure that the filter screen is basically completely covered to ensure the effect of backwashing. A water receiving groove 13 for receiving the rainwater falling from the water receiving tray 9 is arranged in the filter cylinder 1. The water receiving groove 13 is connected to a water storage tank 14. An elastic extrusion assembly 15 is fixedly arranged in the filter cylinder 1. The elastic extrusion assembly 15 includes a fixed rod 16 arranged horizontally. The fixed rod 16 is fixed to the bottom of the water receiving groove 13. A sliding rod 17 is radially penetrated through the fixed rod 16. An extrusion block 18 is connected to the bottom of the sliding rod 17. A return spring 19 is arranged between the extrusion block 18 and the fixed rod 16. The return spring 19 is sleeved on the sliding rod 17. When the water storage bladder 10 is rotated to the side close to the sewage outlet 3, the elastic extrusion assembly 15 squeezes out the water in the water storage bladder 10 to backwash the filter screen 7. When this initial rainwater ecological purification device is in use, rainwater and sundries enter from the water inlet 2. After being filtered by the filter screen 7, the rainwater falls from the filter screen 7, and the sundries remain in the miscellaneous storage space 8. The falling rainwater falls onto the water receiving tray 9. When the water storage bladder 10 is not full, the rainwater enters the water storage bladder 10 through the one-way water inlet pipe 11. After the water storage bladder 10 is full, the rainwater overflows from the outer periphery of the water receiving tray 9 and flows into the water receiving groove 13, and then flows into the water storage tank 14 from the water receiving groove 13. After being used for a period of time, the first motor 4 is used to drive the rolling cylinder 5 to rotate to switch the filter screen 7. The sundries in the miscellaneous storage space 8 are carried to the sewage outlet 3 by the rotation of the rolling cylinder 5 and discharged from the sewage outlet 3. And when the filter screen 7 is rotated to the lower side, the extrusion block 18 squeezes the water storage bladder 10, and the water in the water storage bladder 10 is sprayed out from the one-way water outlet nozzles 12, thereby backwashing the filter screen 7, so that the small particle sundries on the filter screen 7 are removed, so that this initial rainwater ecological purification device can operate continuously for a long time.

[0028] In this embodiment, the water inlet 2 is located at the top of the filter cylinder 1, and a grille 20 is arranged outside the water inlet 2. This initial rainwater ecological purification device is generally installed below the ground, and the grille 20 is set to improve safety and prevent people from stepping on and falling at the water inlet 2.

[0029] In this embodiment, the extrusion block 18 is arc-shaped, and bent guide rods 21 are arranged on both sides of the water receiving tray 9. The water receiving tray 9 is fixedly connected to the rolling cylinder 5 through the guide rods 21. The extrusion block 18 squeezes the water storage bladder 10 under the guidance of the guide rods 21. The guide rods 21 can be used to position the water receiving tray 9 and guide the extrusion block 18. When the rolling cylinder 5 rotates, the guide rods 21 can cooperate with the extrusion block 18 to compress and reset the return spring 19, making the rotation of the roller and the telescoping of the elastic extrusion assembly 15 smoother.

When brushing the filter screen 7, the roller 31 will first contact the rolling cylinder 5 and the filter screen 7. Under the action of the first spring 32, the elastic force between the roller 31 and the filter screen 7 can be adjusted adaptively, driving the position between the brush plate 33 and the filter screen 7 to be adjusted, and preventing excessive force between the brush plate 33 and the filter screen 7 or the rolling cylinder 5, resulting in damage to the filter screen 7 or the rolling cylinder 5.

[0033] In this embodiment, the elastic frame 24 is composed of two vertical plates 34 and a U-shaped bracket 35 connecting the two vertical plates 34.
