Description
Technical Field
The invention belongs to the technical field of river dredging, and relates to a floating mud dredging device, in particular to a river mouth floating mud dredging device for relieving channel dredging pressure.
Background
The floating mud of river is usually formed by the mixture of clay, silt, organic matters and various minerals, which are deposited on the bottom of the channel back siltation through the actions of long-time physics, chemistry, biology and the like and the water body transmission.
Along with the rapid development of economy, water bodies such as rivers, lakes, river entrance beaches and the like are polluted to different degrees, and pollutants in the water bodies can be combined with bottom mud particles at the bottom of the water bodies through the functions of precipitation, complexation or adsorption and the like, so that the content of pollutants in a plurality of river bottom mud is seriously out of standard. The main pollutants in the bottom mud comprise heavy metal pollution, nutrient element pollution, organic matter pollution and the like. Under the action of water flow disturbance and the like, pollutants can be released into the water body, so that hidden danger is brought to water use safety of the water body.
Dredging can relieve dredging pressure of the channel and avoid secondary pollution.
The current engineering dredging technology can be generally divided into dry engineering dredging and wet engineering dredging, wherein the dry engineering dredging refers to pumping water, after the natural air-drying water content of dredged sediment is reduced to a certain value, adopting land construction machinery to perform earth excavation construction, namely, digging and loading dredged objects on a dump truck by using the earth excavation machinery, and transporting the dredged objects to a designated place by the dump truck for piling, and the dry engineering dredging has the characteristics of low sediment water content and small volume, but can lead the sediment containing pollutants in a treatment basin to be exposed to the air for a long time in the operation process, thus being extremely easy to cause harm to the surrounding environment and operators; the wet engineering dredging can better control the secondary pollution to the environment, but the design form of the dredger reamer determines that the dredger reamer can generate larger disturbance to the water body in the operation process, so that pollutants in the bottom mud migrate to the upward water body, and the water body in the dredging area can be adversely affected. Engineering dredging is used as a common dredging method in the current water conservancy industry, the technology and equipment are mature, and the dry engineering dredging has strong adaptability to seasonal rivers.
Through searching, for example, chinese patent literature discloses a lake and river environment-friendly dredging sludge rapid dehydration device [ application number: CN202120554246.9; publication No.: CN214881044U ]. Such devices include soil pits; the soil pit comprises a mud storage dewatering layer for containing the dredged mud, a blocking layer which is positioned at the downstream of the mud storage dewatering layer and used for blocking the dredged mud of the mud storage dewatering layer, and a vertical water filtering mechanism which penetrates through the mud storage dewatering layer and the blocking layer and is vertically distributed along the soil pit and is used for blocking solid mud in the dredged mud and enabling water in the dredged mud to pass through, and a drainage layer which is positioned at the downstream of the blocking layer and at the output end of the water filtering mechanism and used for receiving water discharged from the water filtering mechanism; the mud storage dewatering layer, the barrier layer and the drainage layer are sequentially distributed in the soil pit from top to bottom. Although the dredged silt rapid dehydration device has good drainage effect and low cost; but it is inconvenient to transfer the operating position, transport and collect the silt.
Based on the above, we propose a river mouth floating mud dredging device for relieving the dredging pressure of the channel; the first aeration mechanism, the second aeration mechanism and the air pressure pump are matched to push the floating mud and the river water, and the first aeration mechanism, the second aeration mechanism and the air pressure pump are matched with the water flow direction to push the floating mud and the river water into the frame for rapid filtration;
the mud filtering crawler mechanism is matched with the frame to filter floating mud and river water, and the mud filtering crawler conveys filtered sediment downwards and falls into a mud discharge port to be collected;
the depth of the feed hopper can be adjusted by matching the mud conveying elevator with the hydraulic lifting base, and meanwhile, the mud conveying elevator can be retracted and released, so that the mud conveying elevator is convenient to retract and release;
the suspension arm mechanism is matched with the frame, so that the frame can be conveniently folded, unfolded and used, and the operation is simple.
