The rain and sewage separation device for the building has the working process that:
in non-rainfall weather, because domestic sewage is discharged discontinuously, the water yield is small, the flow velocity is slow when passing through the water inlet pipe 2 and the nozzle 16, and water flow cannot cross the overflow weir 5 and directly enters the sewage discharge chamber 6 and flows into a sewage pipeline in a building community through the sewage discharge pipe 3.
In the early stage of rainfall, the initial rainwater with high pollutant content and small flow enters the sewage discharge chamber 6 through the water inlet pipe 2 and the nozzle 16 and enters a sewage pipeline in a building community through the sewage discharge pipe 3 due to the small flow velocity. In the middle stage of rainfall, when cleaner rainwater with larger flow passes through the nozzle 16, the flow velocity is further increased, and the rainwater directly passes over the overflow weir 5 and enters the rainwater discharge chamber 7; the kinetic energy of the rainwater is reduced through the water drop ladder 13, and then the rainwater enters a rainwater pipeline connected into a building community through the rainwater discharge pipe 4 after being filtered by the sand filter layer 15. In the later stage of rainfall, the flow of rainwater is gradually reduced, the flow speed is also reduced, so that the rainwater cannot cross the overflow weir 5 and can be intercepted in the sewage discharge chamber 6, and when the rainwater in the rainwater collection groove 10 is not enough to compress the spring 11 so that the sewage gate 9 seals the sewage discharge pipe 3, the rainwater enters a sewage pipeline in a building community through the sewage discharge pipe 3; when the rainwater in the rainwater collection tank 10 is enough to compress the spring 11 to make the sewage gate 9 close the sewage drain pipe 3, the rainwater is accumulated in the sewage discharge chamber 6, overflows and enters the rainwater discharge chamber 7 and is discharged by the rainwater drain pipe 4.
When the rain falls continuously and the rainfall is small, the rainwater can not directly cross the overflow weir 5 to enter the rainwater discharge chamber 7 through the nozzle 16, and the rainwater and sewage can be distributed in an overflow mode at the moment. Under the rainfall condition, the rain collecting groove 10 can collect rain water, and meanwhile, the rain discharging port can continuously discharge water; along with the increase of the rainfall in the rain collecting groove 10, the spring 11 can gradually contract to drive the sewage gate 9 to do descending motion along the gate track 8, and the sewage discharge pipe 3 is gradually blocked; when the collected rainfall reaches the maximum value, the sewage gate 9 descends to the lowest height, and the pipe orifice of the sewage discharge pipe 3 is completely sealed at the moment; the water level in the sewage discharge chamber 6 constantly rises, and when the water level exceeded overflow weir 5, the rainwater overflow got into rainwater discharge chamber 7, flowed through drop ladder 13 and sand filter 15, and then got into municipal rainwater pipe network through rainwater calandria 4. When the rainfall is finished, the rainwater in the rainwater collection groove 10 is continuously discharged through the rainwater discharge port, the weight is continuously reduced, and the spring 11 pushes the sewage gate 9 to gradually rise along the gate track 8; when the rainwater in the rainwater collecting groove 10 is completely drained, the spring 11 is reset, the sewage gate 9 rises to the highest point, and the sewage draining pipe 3 is completely opened.
Example 2:
the present example is the same as example 1 except for the following technical features:
as shown in fig. 3 and 4, the gate assembly includes a gate rail 8, a spring 11, and a sewage gate 9; the vertical both sides of installing in sewage calandria 3 end of intaking of gate track 8, sewage gate 9 slidable mounting is in gate track 8, sewage gate 9 is connected with collection rain subassembly, sewage gate 9 cooperatees with sewage calandria 3 end of intaking, the one end of spring 11 is connected with the bottom plate of sewage discharge chamber 6, the other end of spring 11 is connected with sewage gate 9. The spring 11 is coated with a rust-proof layer or an existing protector is installed on the outer circumference of the spring 11. The area of the sewage gate 9 is larger than the area of the pipe orifice of the sewage discharging pipe 3 so as to close the sewage gate 9.
A gap is arranged between the water inlet end of the sewage draining pipe 3 and the bottom plate of the box body 1, and the gap is larger than the height of the compressed spring 11. This arrangement allows the sewage gate 9 to completely close the sewage conduit.
The rain collecting assembly comprises a rain collecting groove 10 and a straight rod 12, the rain collecting groove 10 is located above the box body 1, one end of the straight rod 12 is connected with the rain collecting groove 10, and the other end of the straight rod 12 penetrates through the box body 1 and is connected with the sewage gate 9. When the rainfall in the rain gutter 10 is sufficient to compress the spring 11, the sewage gate 9 moves downward to close the sewage discharge pipe 3; when the rainfall amount of the rain collecting groove 10 is not enough to compress the spring 11, the spring is restored to drive the sewage gate 9 to move upwards so as to open the sewage discharging pipe 3.
As shown in fig. 6, the bottom of the sewage discharge chamber 6 is opened with a water leakage hole 17, and the water leakage hole 17 is communicated with the water discharge end of the sewage discharge pipe 3 through a pipeline. Through setting up the hole that leaks, be convenient for with the sewage discharge between sewage calandria 3 and the box 1 bottom plate in the sewage discharge chamber 6, prevent that sewage from gathering, the internal environment of pollution box. When the water leakage prevention device is used specifically, the water leakage holes are closed for a long time, and the water leakage holes are manually opened through periodic maintenance of the detachable side wall to prevent blockage.
