Description

A detachable and environmentally friendly rainwater outlet that can pretreat rainwater

technical field

The utility model relates to the field of drainage systems, in particular to a detachable environmental protection rainwater gully capable of preprocessing rainwater.

Background technique

A storm drain is a structure on a storm drain that collects rainwater. The rainwater on the road first passes through the gully and then flows into the drainage channel through the connecting pipe. At present, the traditional rainwater grate can only intercept large pollutants such as branches and stones through rainwater grate, but basically has no interception effect on pollutants such as suspended solids in rainwater. Studies have shown that the rainwater in the early stage of rainfall contains a large amount of pollutants, and the concentration of some pollutants even exceeds the index of conventional domestic sewage and directly enters the water body, causing a large degree of pollution.

As the entrance of rainwater into the drainage system, an environmentally friendly rainwater outlet with interception and adsorption functions is used to treat the initial rainwater, reduce the concentration of pollutants such as suspended solids, and reduce the entry of small-sized gravel into the rainwater pipeline, which is beneficial to protecting the urban water environment and reducing drainage. System maintenance is of great significance.

Most of the existing environmental protection rainwater inlets have a certain treatment effect on the initial rainwater, but they cannot match the structural type of the traditional rainwater inlets. They can only be constructed through the overall construction method, which is expensive and difficult to promote in the old city. . Therefore, there is an urgent need for a sewage interception gully that matches the structure of the traditional gully and can pretreat rainwater.

Utility model content

The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art, and to provide a kind of rainwater inlet that can be matched and installed with the traditional rainwater inlet structure, can be easily disassembled, has a long service life and is low in cost, and can pre-treat the rainwater while intercepting sewage. Storm drains for pollutants such as suspended solids.

In order to achieve the above object, the technical scheme of the present utility model is achieved in this way:

A detachable environmental protection rainwater inlet capable of preprocessing rainwater, comprising a main body of the rainwater inlet, a drainage outlet at the bottom thereof, and a grate arranged on the water inlet, and a support frame is arranged on the boss on the lower side of the grate; The support frame is provided with a water filter frame extending to the bottom of the main body of the rainwater inlet; the bottom surface of the water filter frame is covered with a filter material bag, and the middle part of the water filter frame is provided with an overflow port higher than the filter material bag; The upper side of the flow outlet is provided with a sewage intercepting hanging basket sleeved on the water filter frame; the bottom surface of the sewage intercepting hanging basket is provided with an intercepting plate blocking the overflow opening.

Further, the overflow port is formed by one of circle, rectangle or hexagon.

Further, the bottom surfaces of the water filter frame and the sewage interception hanging basket are all grid-shaped.

Further, the water filter frame and the sewage interception hanging basket are both made of PVC material.

Further, the support frame is made of stainless steel.

Further, the filter material in the filter bag is ceramsite, activated carbon or quartz sand.

Compared with the prior art, the utility model has the following beneficial effects:

1. Compared with the prior art, the present utility model solves the problem of initial rainwater pollution on the basis of the traditional rainwater inlet. The support frame, water filter frame, sewage interception basket and filter bag are all detachably arranged on the rainwater inlet, which is easy to install and replace, and it is easy to transform the existing traditional rainwater inlet into an environmental protection rainwater outlet, which saves costs.

2. The support frame in the rainwater outlet is made of stainless steel, and the sewage interception basket and the water filter frame are made of PVC, which has the characteristics of long service life and corrosion resistance, and low production and construction costs. scale promotion.

Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

As shown in Figures 1 and 2, a detachable environmental protection rainwater inlet capable of pretreatment of rainwater includes a main body 1 of the rainwater inlet, a drainage outlet 7 at the bottom thereof, and a grate 2 provided on the water inlet. 2. A support frame 3 is arranged on the boss on the lower side; a water filter frame 4 extending to the bottom of the main body 1 of the rainwater inlet is set up in the support frame 3; The middle of the water frame 4 is provided with an overflow port 9 that is higher than the filter material bag 6; the upper side of the overflow port 9 is provided with a sewage interception hanging basket 5 sleeved on the water filter frame 4; the sewage intercepting hanging basket The bottom surface of 5 is provided with an intercepting plate 8 that blocks the overflow port 9; the bottom surfaces of the water filter rack 4 and the sewage interception hanging basket 5 are mesh-shaped; the overflow port 9 is formed of a circle, a rectangle or a hexagon. The water filter frame 4 and the sewage interception hanging basket 5 are both made of PVC material; the support frame 3 is made of stainless steel.

Wherein, the middle of the water filter frame 4 is provided with an overflow port higher than the filter material bag 6, which can ensure that when the filter material bag is blocked by sundries, rainwater can flow out from the overflow port to ensure smooth drainage of rainwater. The overflow opening 9 is formed by one of circular, rectangular or hexagonal shapes.

Wherein, the upper side of the overflow port 9 is provided with a sewage interception hanging basket 5 sleeved on the water filter frame 4 ; The sewage interception basket can intercept the larger debris in the rainwater and pretreat the rainwater. The baffle on the upper side of the overflow port can prevent rainwater from being directly discharged from the overflow port of the water filter frame, ensuring that the suspended solids and harmful chemicals in the rainwater can be fully absorbed by the filter bag.

The utility model is suitable for being installed in the old urban area with many traditional rainwater gully, and can perform secondary pretreatment on the rainwater entering the rainwater gully in the initial stage. For the first time, the larger debris in the rainwater is intercepted by the sewage interception basket, and the second time is to intercept the fine debris in the rainwater through the water filter frame and the filter bag, and absorb the suspension in the rainwater through the filter material in the filter bag. Solid or harmful chemical substances, realize the pretreatment of rainwater, and then let the rainwater after two pretreatments be discharged into the rainwater system through the drain. Moreover, the materials of the support frame, the water filter frame and the sewage intercepting basket have the advantages of long service life and corrosion resistance, which reduces the use cost. The interception basket can usually be cleaned once every three months, and the filter bag can usually be replaced once every six months, which is convenient for replacement and disposal.

Wherein, the filter material in the filter material bag 6 is ceramsite, activated carbon or quartz sand, the sewage treatment effect is good, and the cost is low.
