Description

Technical Field

[0001] The invention belongs to the technical field of rainwater purification, in particular to an initial rainwater ecological purification device. Background Art

[0002] The initial rainwater purification device is a device used to collect and preliminarily purify initial rainwater, intercepting large pollutants such as cigarette butts and leaves, reducing pollutants in rainwater, and reducing pollution to urban drainage systems and receiving water bodies. It is mainly used on both sides of roads such as urban main and secondary roads, branch roads, leisure squares, traffic squares, etc. After purification, rainwater is recycled and stored for irrigation, road cleaning, etc.

[0003] Chinese patent CN218421503U discloses an initial rainwater storage and purification device, including an interception well, an interception chamber, and a purification chamber. An overflow wall is arranged in the interception well, and the overflow wall divides the inner cavity of the interception well into two areas, one of which is connected to the rainwater pipe network through an overflow pipe, and the other area is provided with a rainwater outlet at the top, and the bottom is connected to the interception chamber through a float and a valve. The interception chamber is connected to the purification chamber through a grille, a lightweight filter material layer is arranged in the purification chamber, and a drain outlet is arranged at the bottom of the purification chamber.

[0004] The above patent has the following deficiencies: when in use, the debris in rainwater is mainly initially filtered through the grille. However, when the amount of rainwater is large, the rainwater will carry more impurities such as leaves, dead branches, and domestic garbage into the device. When the mesh holes on the grille are blocked, the circulation of rainwater in the device will be seriously affected. Although the rainwater will flow over the interception wall into the rainwater pipe network, the rainwater will also carry garbage and impurities into the pipe network, which will block the pipe network. No matter how the rainwater flows in the device, the garbage and impurities brought in from the ground will remain in the device and are inconvenient to clean, affecting the sustainable use of the device. Summary of the invention

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

The water receiving tray 9 does not have to completely catch the rainwater falling from the filter screen, as long as the water storage bag 10 can be filled with the water caught by the water receiving tray 9. The one-way water outlet nozzles 12 do not need to completely and evenly cover the filter screen, as long as the water sprayed therefrom can basically completely cover the filter screen, and the water spraying direction of the one-way water outlet nozzles 12 can ensure that the filter screen is basically completely covered to ensure the backwashing effect. A water receiving trough 13 for receiving rainwater falling from the water tray 9 is provided in the filter cartridge 1, and the water receiving trough 13 is connected to the water storage tank 14. An elastic extrusion component 15 is fixedly provided in the filter cartridge 1, and the elastic extrusion component 15 includes a transversely arranged fixing rod 16, and the fixing rod 16 is fixed to the bottom of the water receiving trough 13.

A reset spring 19 is provided between the extrusion block 18 and the fixing rod 16, and the reset spring 19 is sleeved on the sliding rod 17. When the water storage bag 10 is rotated to the side close to the sewage outlet 3, the elastic extrusion component 15 squeezes out the water in the water storage bag 10 to backwash the filter screen 7. When this initial rainwater ecological purification device is in use, rainwater and debris enter from the water inlet 2, and after being filtered by the filter screen 7, the rainwater falls from the filter screen 7, and the debris remains in the storage space 8. The falling rainwater falls on the water receiving tray 9. When the water storage bag 10 is not full, the rainwater enters the water storage bag 10 through the one-way water inlet pipe 11. After the water storage bag 10 is full, the rainwater overflows from the outer periphery of the water receiving tray 9 and flows into the water receiving trough 13, and flows from the water receiving trough 13 into the water storage tank 14.
