Abstract
The utility model provides an integral hydraulic dredging implement for excavating and transporting sediment, which comprises an implement body with a sediment discharge tube. The implement body comprises a water tank (2) and a high-pressure water pump (1) connected with the water tank (2), nozzles (3) are mounted in the middle of the water tank (2), ducts (4) are disposed in front of the nozzles (3), and a spray board (5) is disposed at the bottom of the water tank (2). The problems of sediment excavation and transportation by the existing dredging and excavating boats can be solved, so that concentration of the excavated and transported sediment is increased, and dredging cost is reduced.
Description
Technical field
The utility model relates to a kind of integral type waterpower dredging tool that excavates, carries silt particle to use of dredging in the industry, belongs to the mechanical device field.
Background technology
Existing dredging dredge boat excavates, need adopt during sediment mining head with mechanical system with the silt cutting or stir pine, the negative pressure that vacuumizes generation by dredge pump sucks dredge pump with silt and is discharged into the appointed area through mud pipe more then.
Following weak point is arranged when existing dredging dredge boat excavation, sediment:
Resistance was big when one, tooth on the mining head or blade excavated silt particle, tooth, cutter wearing and tearing severity.
Two, dredge pump work the time is subjected to sand erosion, and maintenance, maintenance workload are big, and running cost is higher.
Three, suck silt and mainly rely on dredge pump to vacuumize the negative pressure suction silt of generation, suck concentration of hydraulic mixture because vacuum less than 1kg/cm2, influences.
The utility model content
The technical problems to be solved in the utility model is: a kind of excavation sediment integral type waterpower dredging tool is provided; the problem that it exists in the time of solving the excavation of existing dredging dredge boat, sediment; thereby improve excavation, sediment concentration, reduce dredging running cost.
In order to solve the problems of the technologies described above; the utility model is by the following technical solutions: a kind of excavation sediment integral type waterpower dredging tool; it comprises the excavation sediment body that has mud pipe; this excavation sediment body comprises water tank and coupled high-pressure hydraulic pump; the middle part of water tank is equipped with nozzle; dead ahead at nozzle is provided with trunnion, and, be provided with jet tray in the bottom of described water tank.
In above-mentioned excavation sediment integral type waterpower dredging tool, in described water tank, also be provided with cavity, the outlet of described trunnion is connected in the cavity.
In above-mentioned excavation sediment integral type waterpower dredging tool, the number of described nozzle is two or more, and the number of described trunnion equates with the number of described nozzle, and nozzle center position and trunnion center are on same straight line.
In above-mentioned excavation sediment integral type waterpower dredging tool, described jet tray is obturator and is connected with water tank, two or more nozzles are installed on the jet tray work plane.
These facility adopt High-Pressure Water to be used for dredging and dredge based on following some principle:
1, the High-Pressure Water under the floodage can cut material, and can pass material movement.
2, the negative pressure of vacuum of High-Pressure Water pressure ratio dredge pump output is much bigger, and High-Pressure Water can provide required pressure of underwater dredging silt and flow.
3, high-pressure hydraulic pump is compared with dredge pump, do not have silt during owing to work and enter in the pump case, thereby damage in impeller is little in the pump case, long service life.
These facility excavate, carry with existing waterpower formula dredge boat dredge boat silt particle mutually specific energy produce following benefit:
1, the water flow pressure owing to high-pressure hydraulic pump output can reach more than tens of kilograms, negative pressure of vacuum than dredge pump output is much bigger, can promote excavation, slurry conveyed concentration, by the same consumption energy ratio, compare with dredge pump with the mining head on the existing dredge boat, novel facility excavate carries the output of silt particle to improve more than 20%.
2, the dredge pump on the existing dredge boat of the high-pressure hydraulic pump of novel facility use is compared, and the pump case damage in impeller is little during work, long service life, and running cost is low, will overhaul behind the dredge pump operation some months, and the water pump time between overhauls(TBO) can extend to more than 1 year.
Description of drawings
Fig. 1 is the structural representation of excavation sediment integral type waterpower dredging tool described in the utility model.
The specific embodiment
Below for a more detailed description to the utility model in conjunction with the accompanying drawings with embodiment.Present embodiment only is the description to the utility model preferred forms, scope of the present utility model is not had any restriction.
Embodiment
As shown in Figure 1, be the structural representation of excavation sediment integral type waterpower dredging tool described in the utility model.Described excavation sediment integral type waterpower dredging tool mainly is made up of high-pressure hydraulic pump 1, water tank 2, nozzle 3, trunnion 4, jet tray 5, cavity 6, mud pipe 7.
Its concrete operating principle is: by high-pressure hydraulic pump 1 aboard ship is installed, the output High-Pressure Water enters water tank 2, current in the water tank divide two direction ejections, the one, the High-Pressure Water that ejects by jet tray 5 excavates silt, the 2nd, the High-Pressure Water that ejects by nozzle 3 carries silt particle and enters cavity 6 by trunnion 4, and current, the silt fluid-mixing that will converge in the cavity are transported to the appointed area through mud pipe 7.
Spraying high-velocity flow on the jet tray is by several spray-holes are installed, spray-hole ejection current excavation silt on jet tray.
The specification type selecting of the pressure of high-pressure hydraulic pump and flow should comprehensively be carried out type selecting and determine by calculating or testing according to the flow of spray-hole injection on the jet tray and the flow and the pressure of pressure and nozzle ejection.
