Through with precipitation tank 37 can make things convenient for sunny day sewage or the dirty mixed sewage of rain when rainfall to get into carry out preliminary sedimentation when in the intake chamber 8, avoid a large amount of mud sediment to get rid of to low reaches treatment facility via this vatch basin and lead to low reaches treatment facility to cause great load, be favorable to improving sewage treatment efficiency.
The split-flow drainage intercepting well can be used for classifying and intercepting different types of drainage in dry rainy seasons, and has the following specific principle:
when it is not raining, the sewage piston 16 and the early rain piston 22 do not cover the sewage inlet 13 and the early rain inlet 31, respectively, and the early rain upper piston 17 and the overflow piston 18 cover the early rain upper inlet 14 and the overflow inlet 15, respectively; because there is no rain, the upstream incoming water is mainly fine-day sewage, and the fine-day sewage enters the water inlet chamber 8 through the water inlet pipe 24, sequentially passes through the small holes in the sewage telescopic pore plate 32 and the sewage water inlet 13, enters the sewage chamber 9, is discharged from the sewage outlet pipe 25 communicated with the sewage chamber 9, and is discharged into the downstream sewage pipeline.
When raining begins, the upstream incoming water is mainly rain-sewage mixed sewage, at this time, because the amount of rainwater is not large, the sewage piston 16 still does not cover the sewage inlet 13, the incipient rain piston 22 also still does not cover the incipient rain inlet 31, and the incipient rain upper piston 17 and the overflow piston 18 still respectively cover the incipient rain upper inlet 14 and the overflow inlet 15; therefore, the rain and sewage mixed sewage still enters the water inlet chamber 8 through the water inlet pipe 24, enters the sewage chamber 9 through the small holes on the sewage telescopic pore plate 32 and the sewage water inlet 13, is discharged from the sewage water outlet pipe 25 communicated with the sewage chamber 9, and is discharged into a downstream sewage pipeline;
under the condition that rainwater continues to flow downwards, as the amount of rainwater is increased continuously, the amount of rainwater and sewage mixed upstream sewage is also increased continuously, rainwater and sewage mixed sewage continues to enter the water inlet chamber 8 through the water inlet pipe 24, firstly enters the sewage chamber 9 through the sewage inlet 13, and is discharged through the small holes in the sewage telescopic pore plate 32, the sewage inlet 13 and the sewage outlet pipe 25 communicated with the sewage chamber 9 in sequence, but as the amount of rainwater and sewage mixed sewage increased in the water inlet chamber 8 is larger than the amount of water discharged into the sewage chamber 9 through the small holes in the telescopic pore plate 32, the water level of the water inlet chamber 8 gradually rises until the water pressure generated by the water inlet chamber just presses the initial rain upper piston 17 downwards to open the initial rain upper water inlet 14 covered by the initial rain upper piston 17, and simultaneously as the initial rain upper piston 17 moves downwards to drive the first linkage rod 20 and the first spring 19 to move downwards, and then the sewage piston 16 moves downwards and covers the sewage inlet 13 through the linkage action of the first linkage rod 20, at this time, the rainwater mixed sewage does not sequentially enter the sewage chamber 9 through the small holes on the telescopic pore plate 32 and the sewage inlet 13, but sequentially enters the initial rain transition chamber 29 through the small holes on the initial rain telescopic pore plate 33 and the initial rain water inlet 14, and enters the initial rain outlet chamber 30 through the initial rain water inlet 31, and is finally discharged into a downstream initial rain pipeline through the initial rain outlet pipe 26 communicated with the initial rain outlet chamber 30 after being intercepted and subjected to sludge deposition treatment by the settling plate 36 in the initial rain outlet chamber 30.
Under the continuous rain, because the amount of rain water is continuously increased, the amount of rain and sewage mixed with the rain and sewage increased in the water inlet chamber 8 is larger than the amount of water discharged into the initial rain transition chamber 29 through the small holes on the initial rain telescopic pore plate 33, so that the water level of the water inlet chamber 8 is continuously increased until the water pressure generated by the water inlet chamber just presses down the overflow piston 18 to open the overflow water inlet 15 covered by the overflow piston 18, meanwhile, the second linkage rod 23 and the second spring 21 are driven by the downward movement of the overflow piston 18 to move downwards, the corresponding telescopic sleeve 35 of the overflow piston 18 is also compressed downwards, the initial rain piston 22 is further driven to move downwards through the linkage action of the second linkage rod 23 and cover the initial rain water inlet 31, the corresponding telescopic sleeve 35 of the initial rain piston 22 is also compressed downwards, and at this time, the rain and sewage mixed with the rain and sewage does not sequentially pass through the small holes on the initial rain telescopic pore plate 33, The initial rain upper inlet 14 and the initial rain lower inlet 31 enter the initial rain outlet chamber 30, but sequentially enter the overflow chamber 11 through the small holes on the overflow telescopic pore plate 34 and the overflow inlet 15, and are discharged into a downstream rainwater pipeline through the overflow outlet pipe 27 communicated with the overflow chamber 11.
After the rain stops, the rain and sewage mixed with rain and sewage stored in the rain in the water inlet chamber 8 and the clear-sky sewage entering from the upstream of the water inlet pipe 24 still sequentially pass through the small holes on the overflow telescopic pore plate 34 and the overflow water inlet 15 to enter the overflow chamber 11, and are discharged into the downstream rainwater pipeline through the overflow water outlet pipe 27 communicated with the overflow chamber 11, at this time, because the rain does not fall any more, the water quantity discharged through the overflow water inlet 15 is larger than the clear-sky sewage entering from the upstream of the water inlet pipe 24, the water level of the water inlet chamber 8 is rapidly reduced, after the water level is reduced to a certain degree, the water pressure generated by the overflow piston 18 is smaller than the restoring pulling force of the second spring 21, at this time, the overflow piston 18 moves upwards to cover the overflow water inlet 15, and the rain piston 22 moves upwards through the linkage action of the second linkage rod 23, and the covered initial rain water inlet 31 is opened, at this time, the rain and sewage mixed sewage in the water inlet chamber 8 does not sequentially pass through the small holes on the overflow telescopic pore plate 34 and the overflow water outlet pipe 27 communicated with the overflow chamber 11 and is discharged into a downstream rainwater pipeline, but sequentially passes through the small holes on the initial rain telescopic pore plate 33 and the initial rain water inlet 14 and enters the initial rain transition chamber 29, and enters the initial rain water outlet chamber 30 through the initial rain water inlet 31, and is then discharged into a downstream pipeline through the initial rain water outlet pipe 26 communicated with the initial rain water outlet chamber 30 and is discharged, as the water level of the water inlet chamber 8 continues to fall, the water pressure generated by the initial rain upper piston 17 is further reduced until the water pressure is smaller than the restoring tensile force of the first spring 19, at this time, the initial rain upper piston 17 moves upwards to cover the initial rain upper water inlet 14, and the sewage piston 16 is moved upwards by the linkage action of the first linkage rod 20, and the sewage inlet 13 is opened, at this time, the rain and sewage mixed sewage in the water inlet chamber 8 does not sequentially pass through the small holes on the initial rain telescopic pore plate 33, the initial rain upper water inlet 14, the initial rain transition chamber 29 and the initial rain water inlet 31 to enter the initial rain water outlet chamber 30 and is discharged by the initial rain water outlet pipe 26, but enters the sewage chamber 9 through the small holes on the sewage telescopic pore plate 32 and the sewage inlet 13 in sequence, and is discharged by the sewage outlet pipe 25 communicated with the sewage chamber 9, and at this time, the whole system is restored to the initial state, namely, the sewage piston 16 and the incipient rain piston 22 do not cover the sewage inlet 13 and the incipient rain inlet 31, respectively, and the incipient rain upper piston 17 and the overflow piston 18 cover the incipient rain upper inlet 14 and the overflow inlet 15, respectively.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
