Description
Technical field
This utility model belongs to sewage treatment area, and in particular to a kind of sewage precipitation device, particularly with regard to being used for
The three-level settlement of sewage system worked above belt feeder in shield tunnel.
Background technology
Shield machine has a lot of sewage in tunneling process, at shield tail, needs to use the sewage of sewage pumped, extraction to first have to
It is discharged into foul water tank.(cleaning mortar jar and is leaked from shield tail the mortar of mortar pipe substantial amounts of silt and mortar in this sewage
Slurry), general couple of days foul water tank settling tank is just filled up by silt, during cleaning foul water tank, if five people clear up simultaneously, is also needed
Will at least one day time cleaning foul water tank during need stop work, leverage work efficiency.If unclear immediately
Reason foul water tank, the silt of deposition enter draining pump with regard to stream, and such sewage pump Jing is often blocked, once blocking must be taken pipe apart and be carried out
Cleaning, if pipe is taken apart cleared up, cannot continue to discharge sewage, and the water at shield tail cannot be extracted out, and if
Shield tail has water construct.If foul water tank is mended after filling up and clears up foul water tank immediately, soil pipe also can be and clear by sludge blockage
Reason soil pipe will be time-consuming, laborious.And this sewage with sludge is once discharged to well head, is extracted into lower ditch, will block
Lower ditch.So needing a kind of device that sewage at shield tail can be carried out preliminary sedimentation, sewage enters sewage after precipitation
Case, can extend the use time of foul water tank.

Device, wherein, Multistage settling device is arranged on the upper end of bracing frame, and sludge conveyer is installed on the water outlet of Multistage settling device
The lower section of mouth；Multistage settling device includes at least 2 sedimentation tanks being sequentially communicated, and entrance and the sewage pump of Multistage settling device connect
Connect, after finishing, the sludge in multi stage precipitation device is gone out with water, setting position is transported to by sludge conveyer.
Preferably, the sludge conveyer is belt, and belt general horizontal is arranged, and belt is concave structure, middle low
Both sides are high.The belt of concave structure is convenient to be transported together by sludge related muddy water, can effectively prevent muddy water in transportation
Middle unrest is spread.
It is further preferred that vertically go up between the highest point of the belt and Multistage settling device water outlet end
Distance is 5-20cm.
Preferably, the sludge conveyer is dolly, provides power by chain, makes dolly advance.
Preferably, the multi stage precipitation device includes three sedimentation tanks being sequentially communicated, respectively first stage precipitation tank, two grades
Sedimentation tank and three-level sedimentation tank, are provided with water inlet, are provided with outlet on three-level sedimentation tank in first stage precipitation tank.
It is further preferred that between the first stage precipitation tank and second-level settling pond, second-level settling pond and three-level sedimentation tank it
Between be provided with flow structure.
Still more preferably, the first stage precipitation tank, second-level settling pond and three-level sedimentation tank bottom be located height according to
Secondary reduction.
Most of sludge can be settled after sedimentation by sewage, and clear water overflows to next precipitation by flow structure
Pond, can both reduce the disturbance to sludge after settlement, and the water after precipitation can flow readily through again.
Preferably, the port of export of Multistage settling device is provided with butterfly valve.
Preferably, the foul water tank that the outlet of Multistage settling device is carried with shield machine is set in pipeline by pipeline communication
It is equipped with for stopping the grid of foreign body.
It is further preferred that the grid is disposed in proximity to the water outlet of Multistage settling device.Grid can will be larger
The foreign body of volume further stops, prevents from accelerating the pipeline for filling up or blocking foul water tank downstream of foul water tank into after foul water tank.
And the set location of grid can unload pipeline, facilitate labor cleaning when the foreign body for stopping is more, it is therefore prevented that pipeline it is stifled
Plug.
The beneficial effects of the utility model are：
Silt in shield tail sewage in shield tunnel can be settled by this utility model, and most silt is fallen in sedimentation,
Clear water after precipitation is entered in the foul water tank that shield machine is carried, due to the silt that carries in the water in foul water tank compared with
It is few, the use time of foul water tank can be extended, manpower is greatlyd save, construction cost is reduced.
As the sludge in foul water tank is reduced, it is possible to effectively prevent sewage blocking sewage pump and soil pipe.It is simultaneously heavy
Silt in the pond of shallow lake can be discharged by putting sediment port butterfly valve after reaching to a certain degree, the sewage at shield tail during spoil disposal sand
Normally take out, do not affect the normal work of shield machine.
