Method for filtering and draining mud entering cabin of trailing suction dredger and implementation device thereof
The invention relates to a method for filtering and draining mud entering a cabin of a trailing suction dredger and an implementation device thereof in the technical field of dredging, a part of a cabin entering pipe is changed into a filtering and draining pipe filled with a filtering medium, and low-concentration mud in the mud is discharged through the filtering medium; and the filtering speed of the low-concentration slurry is adjusted by adjusting the pressure difference between the front and back of the filtering medium. The implementation device comprises a permeable pipe, a drainage pipe, a pressure regulating valve and a pressure sensor. The permeable pipe is structurally divided into three layers, the inner layer is a filter layer with a filter medium, the middle layer is a drainage layer, and the outer layer is a frame layer. The drainage pipe is communicated with the middle drainage layer of the permeable pipe; the rear end of the pressure regulating valve is connected with the cabin inlet pipe and is used for regulating the pressure difference between the inner side and the outer side of the filtering medium; the pressure sensors are arranged on the inner and outer sides of the filter medium. While the mud conveying function of the pipeline is reserved, the mud entering the cabin is separated, so that the cabin entering flow of the trailing suction dredger is reduced, the cabin entering mud concentration is improved, and the cabin loading operation efficiency is improved.
一种疏浚技术领域的耙吸挖泥船进舱泥浆过滤排水方法及其实施装置，将部分进舱管改成装有过滤介质的过滤排水管，通过过滤介质把泥浆中的低浓度泥浆排出；并通过调节过滤介质前后的压差，来调节低浓度泥浆的过滤速度。实施装置包括透水管、排水管、压力调节阀、压力传感器；透水管其结构共分为三层：内层是带有过滤介质的过滤层，中间层是排水层，外层是框架层；排水管与透水管的中间排水层相连通；压力调节阀的后端与进舱管相连接，用于对过滤介质内外侧的压差进行调节；压力传感器布置在过滤介质的内外侧。本发明在保留管道输送泥浆功能的同时，对进舱泥浆进行分离，从而降低耙吸挖泥船进舱流量、提高进舱泥浆浓度，实现装舱作业效率的提升。
