Description

Drainage system for promoting drainage smoothness

Technical Field

The utility model belongs to the sand filter field especially relates to a promote unobstructed drainage system of drainage.

Background

In the existing municipal sewage treatment plant, a depth treatment unit adopts a V-shaped filter tank and an ozone process, the V-shaped filter tank adopts a homogeneous quartz sand filter material, and a back flushing form of air-water back flushing and surface washing is adopted, so that the filtering and back flushing effects are good. The process is mainly applied to the depth of sewage, the quartz sand for filtering is sea sand in a specific area, the process is generally suitable for deep treatment of large and medium water plants and sewage treatment plants, a filtering head of 2.5m is applied, and each group of filtering pond corresponds to a respective water outlet gallery and a water falling weir therein. When the filtering pond produces water, get into closed drainage channel from the gallery waterfall weir that goes out, and then flow to follow-up advanced treatment section, ozone technology promptly, wherein, when water falls into closed drainage channel from the waterfall weir, the aquatic can be mingled with a large amount of air, hinders the water and flows, and then leads to leading to flowing water smoothly, appears unable waterfall even, water from the problem that the gallery that goes out overflows.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention aims to provide a drainage system for promoting unobstructed drainage, so that gas mixed in water can be timely discharged, accumulation in a closed drainage channel can be avoided, and unobstructed drainage channel can be ensured.

In order to achieve the above purpose, the technical scheme of the utility model is realized as follows:

the utility model provides a promote unobstructed drainage system of drainage, includes the filtering pond, falls weir and ditch, through the pipeline intercommunication between filtering pond delivery port and the fall weir water inlet, falls the delivery port and the ditch intercommunication of weir, the ditch upper end has the return bend of bending downwards through the pipeline intercommunication, and the height that highly is higher than the surface of water in the fall weir of return bend export.

Furtherly, be equipped with the vault portion on the drainage channel, vault portion top is the arc of evagination, the return bend passes through pipeline and vault portion top intercommunication, and the extreme case offal is filled the drainage channel, ensures that the air still can be discharged through the pipeline.

Furthermore, a manhole is arranged on the drainage channel, the bent pipe is connected with the manhole through a pipeline, and a mounting hole for the pipeline to penetrate through is formed in the manhole.

Furthermore, a reinforcing rib is fixedly arranged between the manhole and the pipeline, so that the connection strength of the manhole and the pipeline is improved.

Furthermore, an electromagnetic valve is arranged on a pipeline between the filter tank and the water drop weir, and the electromagnetic valve is used for controlling the discharge of water in the filter tank.

Further, the water outlet of the drainage channel is communicated with the ozone contact tank through a pipeline.

Further, the elbow is U-shaped.

Furthermore, an observation window is arranged on the water falling weir.

Compared with the prior art, promote unobstructed drainage system of drainage have following advantage:

promote unobstructed drainage system of drainage on closed drainage canal through pipeline intercommunication return bend, the air that mix with in the drainage canal aquatic can in time be discharged through the pipeline, avoid piling up in drainage canal, simple structure, reasonable in design effectively improves the patency of drainage, has ensured the normal operating in filtering pond and ozone contact pond, has ensured quality of water safety.

Drawings

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

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

As shown in fig. 1, the utility model discloses a promote unobstructed drainage system of drainage, including the filtering pond, drop weir 1 and drainage canal 2, communicate through filtering pond outlet pipe 3 between filtering pond delivery port and the 1 water inlet of drop weir, be equipped with solenoid valve 9 on filtering pond outlet pipe 3, drop weir 1's delivery port and drainage canal 2 communicate, be equipped with outstanding vault portion 6 on the drainage canal 2, vault portion 6 is equipped with manhole 7 the top, be equipped with the mounting hole on the manhole 7, install vertical connecting pipe 4 in the mounting hole, vertical connecting pipe 4 sets up with manhole 7 is perpendicular, vertical connecting pipe 4 the top intercommunication has the return bend 5 of bending downwards, the height that highly is higher than the surface of water in drop weir 1 of return bend 5 export, return bend 5 in this embodiment is the U type, manhole 7, return bend 5, vertical connecting pipe 4 material is galvanized iron.

The utility model discloses a promote unobstructed drainage system's of drainage work flow as follows:
