Abstract
The utility model discloses a full-closed and pollution spreading preventive device special for environmental protection dredging and reclamation, relates to a special for dredging and reclamation engineering, and aims to solve the technical problem of providing a full-closed and pollution spreading preventive device special for environmental protection dredging and reclamation. The technical scheme of the utility model adopts an anti-spreading environmental protection dredging excavator, a mud extrusion promoting device, a conveying pipeline, a high-pressure water pump and a water return pipeline, and is characterized in that a dredge outlet of the anti-spreading environmental protection dredging excavator is connected with the mud extrusion promoting device; the outlet of the mud extrusion promoting device is connected with the conveying pipeline; the water outlet of the high-pressure water pump is connected with the conveying pipeline; and the mire water return pipeline is connected with the water inlet of the high-pressure water pump. The utility model is a device for the environmental protection dredging and the reclamation of the seashore, the riverbank, inland rivers and lakes.
Description
Technical field
The utility model relates to dredges the device of using with the hydraulic reclamation engineering.
Background technology
In existing environmental dredging and the hydraulic reclamation engineering, generally by excavate facility with earth stir the pine back by the dredge pump suction again through line transportation in mire.During the hydraulic reclamation, the surplus water of hydraulic reclamation in the mire will be discharged outside the mire, when excavating polluted bed mud, the pollutant load of discharging water body be had strict control.Common method is to adopt the dosing input at present, but workload and cost are bigger.The hydraulic reclamation remained water discharge is core technology of constantly exploring and improving in environmental dredging and the hydraulic reclamation engineering.
The utility model content
The utility model technical issues that need to address provide a kind of environmental dredging and hydraulic reclamation isolated plant of totally-enclosed, anti-pollution diffusion.
The technical solution of the utility model adopts the non-proliferation environmental dredging to excavate facility, earth extruding propulsion plant, conveyance conduit, high-pressure hydraulic pump, water return pipeline, it is characterized in that the non-proliferation environmental dredging excavates the dredging soil outlet connection earth extruding propulsion plant of facility, the outlet of earth extruding propulsion plant connects conveyance conduit, the high-pressure hydraulic pump delivery port is connected on the conveyance conduit, and the mire water return pipeline connects the high-pressure hydraulic pump water inlet.High concentration clod or mud that the High-Pressure Water that the utility model is sprayed by high-pressure hydraulic pump will be pressed in the conveyance conduit are delivered directly to mire, the surplus water of hydraulic reclamation in the mire is got back to the water inlet entrance of high-pressure hydraulic pump through return pipe, whole excavation, carry to form one totally enclosed, the environmental dredging process of pollution-free diffusion.
The utility model is owing to carry earth with the high-pressure hydraulic pump water filling, water pump is compared and can be increased substantially than dredge pump application life, at present the environmental dredging transportation concentration is subjected to that dredge pump influences with excavation depth on the ship, generally in 30%, adopts this device transportation concentration having on the basis raising now more than 20%; Along with the raising that enters concentration of hydraulic mixture in the mire, the hydraulic reclamation storage capacity of mire also can reduce, and the amplitude that reduces can reach more than 20%; Because the surplus water circulation of hydraulic reclamation is used in the mire, can avoid mire internal contamination water body to flow into peripheral waters, causes secondary pollution; Therefore, this device has that assembling is easy, transportation concentration is high, cost is low, easy construction, free of contamination advantage, is once completely newly changing anti-pollution diffusion in the environmental dredging field.
Description of drawings
Fig. 1 is totally-enclosed, anti-pollution diffusion environmental protection dredger schematic diagram.
Fig. 2 is totally-enclosed, anti-pollution diffusion environmental protection dredger construction operation flow chart.
The specific embodiment
The utility model (accompanying drawing 1) adopts the non-proliferation environmental dredging to excavate facility 1, earth extruding propulsion plant 2, long-distance transmission pipeline 3, high-pressure hydraulic pump 4, long apart from water return pipeline 5, the non-proliferation environmental dredging excavates facility 1 and selects for use the dredging of screw reamer one class to excavate facility, has to excavate that planeness is good, the extruding advantage that thrust is big, non-proliferation is effective; Earth extruding propulsion plant 2 is located at the top of screw reamer, conveyance conduit 3 is located at earth extruding propulsion plant 2 tops, high-pressure hydraulic pump 4 outlets one end is connected with conveyance conduit 3, the other end is connected with water return pipeline 5, mire 6 is the stacking ground that stores dredging soil, and water return pipeline 5 is connected to high-pressure hydraulic pump 4 water inlets from the mire outfall.The utility model (accompanying drawing 2) enters long-distance transmission pipeline by the dredging soil that non-proliferation environmental dredging excavation facility will excavate through earth extruding propeller, high concentration clod or mud that the High-Pressure Water that is sprayed by high-pressure hydraulic pump will be pressed in the conveyance conduit are delivered directly to mire, the surplus water of hydraulic reclamation in the mire is got back to the water inlet inlet of high-pressure hydraulic pump through return pipe, mire outfall place height is higher than high-pressure hydraulic pump place height, and backwater relies on the gravity flow mode to finish.The utility model excavates, carries construction formation totally enclosed, the environmental dredging process of pollution-free diffusion.
Claims (2)
1. the environmental dredging and the hydraulic reclamation isolated plant of totally-enclosed, an anti-pollution diffusion, adopt the non-proliferation environmental dredging to excavate facility, earth extruding propulsion plant, conveyance conduit, high-pressure hydraulic pump, water return pipeline, it is characterized in that the non-proliferation environmental dredging excavates the dredging soil outlet connection earth extruding propulsion plant of facility, the outlet of earth extruding propulsion plant connects conveyance conduit, the high-pressure hydraulic pump delivery port is connected on the conveyance conduit, and the mire water return pipeline connects the high-pressure hydraulic pump water inlet.
2. the environmental dredging and the hydraulic reclamation isolated plant of a kind of totally-enclosed, anti-pollution diffusion according to claim 1 is characterized in that it is that facility are excavated in the screw reamer dredging that the non-proliferation environmental dredging excavates facility.
