Description

Harbour sludge treatment device and its processing method
Technical field
The present invention relates to a kind of harbour sludge treatment device and its processing method, belong to port and pier technical field.
Background technology
It more generally there is Sediment Siltation in harbour.Harbour is often back-silted after excavating, and need to be safeguarded with dredging.Nothing In the case of shielding, hand excavation only influences local waters, and surrounding environment still keeps original water movement and Sedimentation condition, Back-silt and tend to restore to the original state in local waters.When having building shielding, surrounding environment will be significantly affected and formed new Water movement and Sedimentation condition, hand excavation waters can improve the depth of water, but have sediment source area wave, trend and It will be back-silted under littoral flow effect.The harbor siltation of river and its Hekou Area and its sedimentary loading are closely related.Main flow is put The influence that dynamic and change in bed level develops is even more important.Harbour is relatively deep and is easiest to back-silt compared with flat water.Therefore, safeguard Property dredging often it is indispensable.This dredging has the characteristics of Seeding location stabilization and regular activity duration, should also conscientiously determine mud Native processing mode and suitable throwing mud ground point, reduce harbour and back-silt.In order to improve the efficiency of maintenance dredging, left coming husky side At a certain distance from hand excavation waters, the pre- dell aggregation silt that digs is advantageous to concentrate dredging.Various dredgings all must be according to waters bottom Matter and environmental condition select corresponding dredger and other dredging instruments.
A such as Application No. CN201649151U discloses a kind of harbor dredging device, is mainly provided with outer tube interior Pipe, inner tube is by sleeve pipe and the central tube being connected is set with it forms, and forms high-velocity fluid passage between outer tube and inner tube, and The extension junction of the narrow taper cavity of high-velocity fluid passage forms α=75-85 ° of jet angle, forms dredging device.In outer tube One end is connected with riser, and the other end is connected with the suction line connected with inner tube central tube, and the side of overcoat 5 through water inlet pipe with Connect the water pump connection of engine.This Accrete clearing device effectively can be drawn into the deep seabed dirts of 45m apart from sea 2.1m's Highly, discharge, and can be 7.8 seabed proportion, a diameter of 500mm iron ball or a diameter of 350mm, length are 2.2m iron rod From seabed cleaning ashore.Not only desilting is very competent for the Accrete clearing device, and dredging effect is good, so as to solve harbour silt The problem of alluvial cleaning is difficult.
And for example an Application No. CN203821473U discloses a kind of efficiently harbour sludge treatment device, including hydraulic suction dredge, The storage hopper dredger being located in the hydraulic suction dredge cabin, it is characterized in that, it is provided with the mechanical box for being used for inhaling mud, mechanical box in the storage hopper dredger Inside, which is provided with, inhales mud equipment;The suction mud equipment includes pasture and water Rose Box, communicating pipe, slush pump and multiple rake suction pipes, the company In siphunculus one end access storage hopper dredger, other end access pasture and water Rose Box is used for the mud after delivery of filtered;The slush pump will The mud that rake suction pipe absorbs is delivered to filtration treatment in pasture and water Rose Box.The utility model has operating efficiency height, dredging capacity The advantages of strong and filter capacity is high, has wide market prospects.
Generally the processing to mud is excavated or is drawn in ship storehouse using dredger, big for some The mud block of block can be difficult to be drawn in ship storehouse using absorption, while if meeting pasture and water and mud together, then take and draw Will be more difficult.
