D, closes Hand-operated butterfly valve c, and trade effluent flows directly out outside hole；
Apart from sewage transport system Pulp pump in described: when length of tunnel is greater than 300 meters less than 1200 meters, pneumatic diaphragm pump
The sewage of pumping reaches foul water tank, and after foul water tank filter screen primary filtration, sewage reaches the suction area of Pulp pump, level sensing
After device detects signal, Pulp pump allows to start, and after liquid level reaches a height, can star Pulp pump for sewage and dirt is discharged
The sewage of water tank, slurry pump discharge is expelled directly out tunnel along the effluent outfall that tunnel is laid with；Pneumatic diaphragm pump is in supply gas pressure
In the case where being 36m3/h for 6bar, sewage quantity, pneumatic diaphragm pump H-Max is 20 meters, rule of thumb when length of tunnel is more than
At 300 meters, sewage cannot be sent out tunnel by pneumatic diaphragm pump, when length of tunnel is greater than 300 meters less than 1200 meters, be opened manual
Butterfly valve c, closes Hand-operated butterfly valve d, and the sewage of pneumatic diaphragm pump pumping reaches foul water tank；Start Pulp pump and foul water tank is discharged in sewage
When, there are Hand-operated butterfly valve e, Hand-operated butterfly valve f, manual ball valve b in slurry pump discharge, closes manual ball valve b, close Hand-operated butterfly valve f, beat
Hand-operated butterfly valve e is opened, the sewage of slurry pump discharge is expelled directly out tunnel along the effluent outfall that tunnel is laid with；
The sewage recycling and reusing system plunger pump: the sewage transport of Pulp pump pumping is delivered to sediment improvement case
After the water of sediment improvement case is mixed with sediment improvement agent, cutterhead or Tu Cang are pumped to by plunger pump, complete to recycle.Due to dirt
Water is expelled directly out tunnel, causes water resource and energy waste, in sewage recycling and reusing system of the invention, designs sewage
Circuit is recycled, in use, closing Hand-operated butterfly valve e, Hand-operated butterfly valve d, Hand-operated butterfly valve f is opened, closes manual ball valve b, Pulp pump
The sewage of pumping is delivered to sediment improvement case after being filtered, Filter Precision 4mm meets sediment improvement and wanted with water
It asks, with level sensing and stirring, the water for being delivered to sediment improvement case mixes sediment improvement case with sediment improvement agent such as bentonite
Afterwards, cutterhead or Tu Cang are pumped to by plunger pump, complete to recycle.There is pressure sensor in slurry pump discharge, for detecting slag
Stock pump outlet pressure prompts pipeline blockage when pressure detecting is higher than 5bar, and when long range sewage transport needs to check sewage
It manages, in the case where reutilization of the sewage, filter element need to be unpicked and washed.
It further include long range sewage transport system, the long range sewage transport system Pulp pump adds pipeline blowdown
Pump: when length of tunnel is greater than 1200 meters, the pipe laying dredge pump on effluent outfall carries out two to the sewage of Pulp pump discharge
The sewage transport of long distance tunnel is realized in secondary pressurization；The present invention due to conventional shield since rear mating trailer space is limited, usually
In the case of the slurry pump discharge selected be 50m3/h, lift is 50m, and the sewage pipe that tunnel is laid with is generally 4 cun, is calculated at this
In the case of kind, the pumping length of Pulp pump can reach 1.2 kilometers, and tunnel piercing mileage needs to use pipeline when being more than this length
Dredge pump, the pipe laying dredge pump on effluent outfall carry out secondary booster to the sewage of Pulp pump discharge, realize over long distances
The sewage transport in tunnel；
Short distance sewage transport trend is: outside trade effluent → pneumatic diaphragm pump → discharge hole；
It is middle to be apart from sewage transport trend: trade effluent → pneumatic diaphragm pump → foul water tank → strainer filtering → Pulp pump → discharge
Outside hole；
Long range sewage transport trend is: trade effluent → pneumatic diaphragm pump → foul water tank → strainer filtering → Pulp pump → conveying
Distance be greater than 1.2 kilometers when → pipeline dredge pump → discharge hole outside.
Reutilization of the sewage process trend is: trade effluent → pneumatic diaphragm pump → foul water tank → strainer filtering → Pulp pump →
Filter → sediment improvement case → plunger pump → cutterhead or Tu Cang.
