Description

Precipitation filtration rainwater collection port

Technical Field

The utility model belongs to the technical field of municipal administration environmental protection, concretely relates to mouth is collected to precipitation filtration rainwater.

Background

The inventor knows that municipal departments mainly have the following two treatment modes for road surface rainwater:

(1) rainwater flows to rainwater collecting ports on two sides of a road through a road surface with a drainage gradient, is directly discharged into a rainwater well and an underground rainwater pipeline through a rainwater port, and is discharged into a river channel through an urban rainwater pipe network system.

(2) The rainwater on the road surface is directly discharged into the green land on the two sides of the road in a natural drainage mode of the road surface for greening irrigation.

The inventor thinks that the pavement runoff rainwater recycling mode has low utilization rate and is easy to cause rainwater resource waste; the rainwater on the road surface is directly discharged without being treated, so that the environment is easily polluted, and the precipitated sludge is not easy to be removed; the rainwater treatment facility has poor treatment effect, so that rainwater contains a large amount of leaves, sludge, impurities and the like, and the recycling requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough of above-mentioned prior art, provide a deposit and filter the rainwater and collect the mouth, can promote the scrubbing effect that deposits and filter the rainwater and collect the mouth, improve the recycle ratio of rainwater.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a mouth is collected to sediment filtration rainwater, includes first cell body and second cell body, the well lower part of first cell body and second cell body is equipped with the mouth of a river, first cell body and second cell body are through crossing water mouthful intercommunication, be equipped with the filter screen in the second cell body, the filter screen is located crosses water mouthful top, the top of filter screen is equipped with the one end of outlet pipe, the other end of outlet pipe stretches out the second cell body.

The first tank body and the second tank body are matched for use, sludge and gravel are precipitated in the first tank body, floatable matters such as plastic bags and fallen leaves are filtered in the second tank body, and a form of filtering rainwater from bottom to top is adopted; impurity separately filters the sediment and from down up filters and can avoid the filter screen to be blockked up promptly.

Furthermore, the first tank body and the second tank body are separated by a baffle, and a water passing port is arranged at the middle lower part of the baffle.

The arrangement mode enables workers to build the integral pool body firstly and then separate the pool body by the baffle plates, so that the working procedures are optimized, and the building efficiency of the rainwater collection port is improved.

Furthermore, the filter screen is of a fold line shape, a second tank body above the filter screen forms a drainage space, and a second tank body below the filter screen forms a filtering space. The filter screen of dogleg shape can increase the filter area of rainwater.

Further, a slope is arranged in the second tank body, and one end, located at the water passing port, of the slope is lower than one end, far away from the water passing port, of the slope. After the rainwater level in the second tank is reduced, the floaters intercepted by the filter screen slide to the first tank body from the slope at the bottom for storage; the centralized storage of sundries is realized.

Further, the axis of the water outlet pipe is horizontally arranged, and the water outlet pipe is used for being communicated with an external drainage channel.

Furthermore, a grate is arranged at the top end of the first tank body. By adopting the structure of the grate, the rainwater collecting port can filter large sundries in advance, and the risk that the filter screen is blocked is reduced.

Further, a cover plate is arranged at the top end of the second tank body. And a special cover plate is adopted for sealing the second tank body, so that the top end of the second tank body is prevented from flowing rainwater to pollute rainwater filtered by the filter screen.

Further, a sludge hopper is arranged in the first tank body at the lower part of the water passing port. The structure of sludge bucket can realize the sediment of mud, grit, can also realize the collection of floater after the rainwater water level descends, convenient clearance.

Further, the cross sections and the depths of the first tank body and the second tank body are the same. The arrangement mode can facilitate construction and reduce construction cost.

The utility model has the advantages that:

the utility model provides a mouth is collected to rainwater sets up precipitation and filterable dual scrubbing structure, can conveniently carry out effective filtration to impurity such as silt, leaf that mix with in the rainwater, and is low through this inlet for stom water exhaust rainwater impurity, and the cleanliness factor is high, realizes clean the emission basically, is favorable to protecting natural environment.

Meanwhile, impurities attached to the filter screen in the rainwater collecting port are collected to the sludge hopper at the bottom of the first tank body through the slope at the bottom of the second tank body, so that the filtered impurities can be conveniently and intensively cleaned; the filter screen adopts broken line type structure, can increase rainwater filtration area, increases rainwater filtration efficiency.

The rainwater collecting port occupies less land, is buried underground, can be arranged on two sides of a road or in a green belt, does not influence the surrounding environment, and is convenient to construct and install and easy to clean and maintain.
