The utility model object realizes being completed by following technical scheme:
A kind of sand pebble layer shield driving dregs is separated emission-reducing system, it is characterized in that: described system comprises roughly selects separation equipment, dehydration separation equipment, concentrator, filtering equipment, press filtration pan feeding mixing plant, reservoir and clear water reserviors, described import of roughly selecting separation equipment is dregs feeding mouth, describedly roughly select the outlet of separation equipment and described dehydration separation equipment inlet communication, the outlet of described dehydration separation equipment and the inlet communication of described concentrator, described concentrator has two outlets, one of them outlet is communicated with described clear water reserviors, the inlet communication of another outlet and described press filtration pan feeding mixing plant, the described outlet of press filtration pan feeding mixing plant and the inlet communication of described filtering equipment, described filtering equipment has two outlets, one of them outlet is communicated with described reservoir, described reservoir is communicated with described clear water reserviors, another port of export is dregs discharging opening.
Describedly roughly select separation equipment, described dehydration separation equipment is communicated with described clear water reserviors respectively.
The utility model has the advantages that: by shield structure dregs process in sand pebble layer, generate the operable construction material such as cobble, sand; By the additive in shield-tunneling construction and Water Sproading recycling, water resource and protection of the environment can be saved; Greatly reduce the amount of outward transport dregs, reduce cost of transportation, decrease the impact on municipal environment such as noise, airborne dust.Not only accomplish energy-saving and emission-reduction, considerable economic benefit can also have been produced.
Accompanying drawing explanation
Fig. 1 is layout schematic diagram of the present utility model.
Detailed description of the invention
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technical staff of the same trade:
As shown in Figure 1, mark 1-15 in figure to be respectively: roughly select separation equipment 1, dehydration separation equipment 2, concentrator 3, Pulp pump 4, press filtration pan feeding mixing plant 5, membrane pump 6, filter press 7, clear water reserviors 8, clarified water pump 9, filtrate pump 10, reservoir 11, submerged pump 12, hook machine 13, mud cake 14, shield structure dregs 15.
Embodiment: as shown in Figure 1, the sandy gravel shield driving dregs in the present embodiment is separated emission-reducing system and is used for isolating from shield structure dregs 15 to have economic worth, the sand that can recycle, cobble and additive and water.Separation emission-reducing system transports shield structure dregs 15 for raw material by hooking machine 13.First shield structure dregs 15 enters the import of roughly selecting separation equipment 1, and this import is the feeding mouth of system, roughly selects between the outlet of separation equipment 1 and the import of dehydration separation equipment 2 and passes through pipeline connection.The dehydration outlet of separation equipment 2 and the inlet communication of concentrator 3, complete the conveying of raw material between the two by submerged pump 12.Concentrator 3 has two outlets, and one of them outlet and the inlet communication of press filtration pan feeding mixing plant 5, complete the conveying of raw material between the two by Pulp pump 4; Another outlet is communicated with clear water reserviors 8.The outlet of press filtration pan feeding mixing plant 5 is connected with the import of filter press 7, is completed the conveying of raw material between the two by membrane pump 6.Concrete two outlets of filter press 7, one of them outlet is communicated with reservoir 11; Another outlet is directly for generating the discharging opening of mud cake 14.The outlet of reservoir 11 is communicated with clear water reserviors 8, completes Liquid transfer between the two by filtrate pump 10.Clear water reserviors 8 with roughly select separation equipment 1 and be connected, carried by clarified water pump 9.
Depend on said system structure, the present embodiment in the specific implementation, has following workflow:
1) cobble is separated: after shield structure 15 feeding is roughly selected the import of separation equipment 1 by hook machine 13, by roughly selecting the cleaning of separation equipment 1 mesohigh water and vibrating driven screen cloth by dither motor, cobble larger for particle diameter in shield structure dregs 15 can be sieved out.The cobble of appropriate particle size is obtained by the large I of adjustable screen.The water under high pressure roughly selected in separation equipment 1 can be pressed out to from any water source by submerged pump 12 to be roughly selected in separation equipment 1, or by by clear water reserviors 8 with roughly select separation equipment 1 and be connected, and utilize water pump to be pressed out to by the clear water in clear water reserviors 8 to roughly select separation equipment 1 interior as water for cleaning.
2) sand separation: the residue shield structure dregs 15 through roughly selecting separation is transported to dehydration separation equipment 2 from the outlet of roughly selecting separation equipment 1 by pumping, dehydration separation equipment adopts the method for isolated by filtration equally, namely by rinsing and vibrating by the sand separation of the modulus of needs out.Obtained the sand of suitable modulus by the large I of adjustable screen, the water of process need provides by clear water reserviors 8.
3) first separation of additive and water: through dehydration be separated shield structure dregs 15 from dehydration separation equipment 2 outlet through being pumped to concentrator 3.Concentrator 3 adopts the method for laminated segregation, namely makes remaining shield structure dregs 15 produce lamination by concentrated high-speed stirred, and its clear water is at the middle and upper levels evacuated in clear water reserviors 8 in order to recycling by clarified water pump.
4) secondary separation of additive and water: in concentrator 3, the slag slurry of lower floor is pumped in press filtration pan feeding mixing plant 5 by Pulp pump 4.Press filtration pan feeding mixing plant 5 carries out uniform stirring by mixing plant to slag slurry, uniform slag slurry is pumped in filtering equipment 7 by membrane pump 6, in filtering equipment 7, by the extruding of gases at high pressure, processed is carried out to slag slurry, and then formation water content is lower than the mud cake of 28%, and the water be press-filtered out is by the filtering-depositing of reservoir 11, clear water (solid holdup≤2g/L) is collected and is pumped to clear water reserviors 8 by filtrate pump 10.
5) in filtering equipment 7, the mud cake of processed is the end product of shield structure dregs 15, and sand, cobble, additive and the water in shield structure dregs 15 is in above-mentioned steps 1)-4) in be separated to recycle.
In order to the isolated water of cyclic utilization system, can by roughly selecting separation equipment 1, dehydration separation equipment 2 is communicated with clear water reserviors 8 respectively, and arrange corresponding water pump to make clear water reserviors 8 for roughly select separation equipment 1 and the separation equipment 2 that dewaters provides work time required flushing water.
