It send to the water of sediment improvement case after being mixed with sediment improvement agent, cutterhead or Tu Cang is pumped to by plunger pump, complete to recycle.By
It is expelled directly out tunnel in sewage, causes water resource and energy waste, in the sewage recycling and reusing system of the utility model,
Reutilization of the sewage circuit is designed, 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, the sewage of Pulp pump pumping are delivered to sediment improvement case after being filtered, and Filter Precision 4mm meets sediment improvement
It is required with water, sediment improvement case is delivered to water and the sediment improvement agent such as swelling of sediment improvement case with level sensing and stirring
After soil mixing, cutterhead or Tu Cang are pumped to by plunger pump, complete to recycle.There is pressure sensor in slurry pump discharge, is used for
Slurry pump discharge pressure is detected, when pressure detecting is higher than 5bar, prompts pipeline blockage, when long range sewage transport needs to check
Sewage pipe in the case where reutilization of the sewage, need to unpick and wash filter element.
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 utility model due to conventional shield since rear mating trailer space is limited,
The slurry pump discharge selected under normal conditions is 50m3/h, and lift is 50m, and the sewage pipe that tunnel is laid with is generally 4 cun, is computed
In this case, the pumping length of Pulp pump can reach 1.2 kilometers, need to use when tunnel piercing mileage is more than this length
Pipeline dredge pump, the pipe laying dredge pump on effluent outfall carry out secondary booster to the sewage of Pulp pump discharge, realize length
Sewage transport apart from 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 →
It is discharged 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.
