Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, be the preferred embodiment of sludge vacuum subcharge combined compressing and dewatering device of the present utility model, form by compression pond 1, filtering layer 2, framework 3, vacuum unit 4, sewage surge tank 5 and preloading device 6; Wherein,
This compression pond 1 is built up by Steel Concrete, and mud compression place is provided, and is laid with discharge pipe line 11 in the pond inner bottom part, and discharge pipe line 11 is communicated to the sewage surge tank 5 of compression 1 outside, pond; This filtering layer 2 is made of and is layed in regular turn the bottom in compression pond 1 blotter 21, geo-grid 22 and non-woven fabrics 23, make blotter 21 be positioned at the lowest layer, laying depth is 20cm, and to get the rubble diameter be 3-6cm, and this geo-grid 22 is layed on this blotter 21, prevent non-uniform settling in order to balanced stress, non-woven fabrics 23 is then laid in the top, and sewage flows in the discharge pipe line 11 in compression pond 1 after this filtering layer 2 filters again; This framework 3 places compression pond 1 to be used for splendid attire mud, be to adopt reinforcing bar to be welded, hole is 10cm at interval, the fixing geonet 31 of one deck band filter membrane in the inboard of framework 3, in order to anti-filter, geonet 31 comprises the cavity volume portion 311 of the medial surface that is fixed in framework 3 and is covered on the cap 312 at cavity volume portion 311 tops, and the drift angle of framework is provided with suspension ring 32, makes things convenient for the lifting rig framework 3 of slinging; This vacuum unit 4 comprises geomembrane 41 and vacuum pump 42, geomembrane 41 closed compression ponds 1, startup vacuum pump 42 vacuumizes to make and produces negative pressure under the geomembrane, water in the mud is sucked out in discharge pipe line 11 is introduced into sewage surge tank 5, vacuum pump 42 is located at outside the mud compression pond 1, this sewage surge tank 5 is connected with vacuum pump 42 by discharge pipe line 12, and sewage surge tank 5 is cylindrical work durm, and the bottom is provided with water discharge valve in order to effluent sewerage; Preloading device 6 is made up of load plate 61 and the concrete blocks 62 that is stacked in load plate 61 tops, is mud in the pond 1 to be compressed when reaching certain degree of consolidation, places preloading device 6 on geomembrane 41, with further compression mud discharge moisture content, reaches best dehydrating effect.
Adopt said apparatus principle of work of the present utility model to be:
Mud is poured into the cavity volume portion 311 of the geonet 31 that is positioned at compression pond 1, lay the cap 312 of geonet 31 then on mud top, lay geomembrane 41 at the top in compression pond 1 again, to embed around the geomembrane 41 in the soil body of compression pond periphery, and the geomembrane 41 in the order compression pond 1 is reserved certain extensible length and is sunk in order to mud with closed compression pond 1; Starting vacuum pump 42 vacuumizes, make geomembrane produce negative pressure 41 times, outside air has applied barometric point to geomembrane 41 simultaneously, make the water in the 1 interior mud of compression pond be sucked out, by compressing the discharge pipe line 11 at the bottom of pond 1 bottom filtering layer, 2 filtrations enter the pond, through discharge pipe line 11 sewage is introduced sewage surge tank 5 row discharge again, reach certain degree of consolidation after the sludge dewatering in the pond 1 to be compressed, on geomembrane 41, add preloading device 6 (being load plate 61 and concrete blocks 62) again mud is done further compression, make moisture content in the mud under the additional stress effect, further discharge, after the predetermined degree of consolidation is arrived in sludge dewatering, lifting rig sheds preloading device 6, slings the framework 3 of fixed back mud is housed, and mud is poured into other transportation equipment do subsequent disposal.
