Description
Technical field
The utility model belongs to sewage disposal system field, is specifically related to a kind of sewage lifting pump station outlet conduit structure.
Background technology
Sewage lifting pump station is indispensable important component part in sewage disposal system, for the elevation of lifting sewage and by sewage lifting pump station outlet conduit structure, sewage transport to Wastewater Treatment Plant is carried out to water treatment.
At present, existing sewage lifting pump station mainly includes collecting-tank and is arranged on many submersible pumps in collecting-tank.Wherein, the outlet conduit structure of existing sewage lifting pump station is: the delivery port by many submersible pumps is connected with one group of outlet conduit respectively, and the height of respectively organizing outlet conduit upper end water outlet differs, and has more turning.In addition, on each group of outlet conduit, be also equiped with respectively water-hammer arrester, in order to eliminate water hammer.But the outlet conduit structure of existing sewage lifting pump station, in use, has following weak point:
1, in outlet conduit, elbow is more, and pipeline rout design is unreasonable, has increased the required energy consumption of lifting sewage, has reduced the operational efficiency of pumping plant.
2, water-hammer arrester is arranged on each group of outlet conduit, has not only increased the practical amount of equipment, has increased the weight of the construction maintenance cost of sewage lifting pump station, meanwhile, also makes on each group of outlet conduit water-hammer arrester eliminate water hammer effect still poor.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how a kind of better sewage lifting pump station outlet conduit structure of electric energy, water hammer eradicating efficacy that can reduce pump machine lifting water consumption is provided.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of sewage lifting pump station outlet conduit structure, it is characterized in that: described outlet conduit structure comprises the collecting-tank body pool wall top wall body structure that upwards extension arranges that is positioned at sewage lifting pump station, also comprise a T-shaped tee pipe fitting and outfall sewer, the arm of described tee pipe fitting is tightly connected with the first outlet conduit upper end that lower end is connected with the first submersible pump in collecting-tank, one end of described tee pipe fitting is tightly connected with the second outlet conduit upper end that lower end is connected with the second submersible pump in collecting-tank, the other end of described tee pipe fitting is connected with one end horizontal seal of described outfall sewer, the described outfall sewer other end has horizontal-extending and passes the horizontal-extending pipeline section of described wall body structure, also comprise water-hammer arrester, described water-hammer arrester is fixedly installed on described horizontal-extending pipeline section.
In sewage lifting pump station outlet conduit structure of the present utility model, the first outlet conduit and the second outlet conduit are communicated with and outfall sewer level connection joint output lifting sewage by T-shaped tee pipe fitting, so farthest reduced turning, make pipeline move towards design more reasonable, impel to such an extent that submersible pump lifting carries the resistance of sewage less, can reduce the electric energy of pump machine lifting water consumption.Meanwhile; water-hammer arrester is arranged on the horizontal-extending pipeline section of outfall sewer; avoid each to branch out waterpipe the waste that brings of water-hammer arrester and undesirable water hammer eradicating efficacy have been installed; can more effectively eliminate the irregular water attack ripple concussion that the water hammer that produces while transmission in outlet conduit and surge occur; thereby eliminate and there is the damage that destructive shock wave causes water hammer pipeline and submersible pump; submersible pump in pumping plant and sewage lifting pipeline are played a protective role, also further increased the reliability and stability of lifting sewage.
As improvement, sewage lifting pump station outlet conduit structure of the present utility model also comprises sleeve member, and described sleeve member level runs through and is fixed on described wall body structure; Described outfall sewer external diameter mates with the interior diameter of described sleeve member and fastens in described sleeve member.
Like this, can pass through the wall body structure of pumping plant self, run through and be fixed on described wall body structure upper bush part in conjunction with level and realize fixing to outfall sewer, the vibrations of avoiding outfall sewer to produce in the time of lifting sewage, help to realize the more reliable and stable operation of pumping plant.
As improvement, described sleeve member is positioned on the external surface at described wall body structure two metope places and is also vertically fixedly installed the right angle flange that a circle contacts with metope, is also fixedly installed at least one circle and extends out to the reinforced sheet in wall body structure on the external surface of described sleeve member between described wall body structure two metopes.
Like this, the right angle flange contacting with wall body structure by being provided with a circle on sleeve member, can be by more firm being fixed on wall body structure of sleeve member.On the external surface of described sleeve member between described wall body structure two metopes, be also fixedly installed at least one circle and extend out to the reinforced sheet in wall body structure, further lift lug barrier part is fixed on the firm degree of wall body structure, further prevents the vibrations that outfall sewer produces in the time of lifting sewage.
As improvement, sewage lifting pump station outlet conduit structure of the present utility model also comprises flap valve, and described flap valve is fixedly installed on described horizontal-extending pipeline section and is positioned at the influent side of described water-hammer arrester.
Like this, after installation flap valve, can avoid sewage in outlet conduit to flow backwards.Because the submersible pump in sewage pumping station is in the time opening or cut out, can in outlet conduit, produce larger water hammer pressure again, when serious, easily cause the damage (especially for large mouthful of pipeline or pressure duct) of equipment on pipeline pipeline or pipeline.After above-mentioned improvement technical scheme is implemented; flap valve and water-hammer arrester are co-located on horizontal-extending pipeline section; the horizontal-extending pipeline section of flowing through of water flow energy quick and stable; therefore when submersible pump is in the time opening or cut out; water hammer pressure by flap valve can be eliminated by water-hammer arrester fast, and flap valve is played to better protective effect.
Sewage lifting pump station outlet conduit structure of the present utility model, have advantages of rational in infrastructure, cost is lower, can reduce the construction maintenance cost of sewage lifting pump station.Can also reduce the electric energy that pump machine promotes water consumption, obtain better water hammer eradicating efficacy.
