Dragging type underwater surface layer semi-sedimentation sludge removing device
The invention relates to the technical field of underwater sewage pumping equipment, and discloses a dragging type underwater surface layer semi-sedimentation sludge removing device which comprises a sewage pumping mechanism which is flexibly connected with a ship through a dragging mechanism on the ship and dragged by the ship to move forwards so that a sewage pumping opening can be located on the surface layer of sludge. The dragging mechanism comprises a bottom plate, a front inclined plate and a sewage pumping bin, a sludge scraping and crushing device is arranged at a sewage pumping opening of the sewage pumping bin and comprises two rotating shafts, the two rotating shafts are fixedly sleeved with a plurality of rolling blades respectively, the two rotating shafts rotate in opposite directions, and surface sludge is scraped to the sewage pumping opening of the sewage pumping bin; and grinding and crushing solids in the sludge. The top of the vacuumizing bin is provided with a sewage pump, semi-settled mud on the surface layer of the sludge is pumped into a cabin under the action of negative pressure pumping when the sewage pump is started, and the purpose of improving the water quality is achieved by specially removing thin mud on the surface layer of the sludge which is most harmful to the water quality.
本发明涉及水底抽污设备技术领域，公开了一种拖拽式水底表层半沉降淤泥清除装置，包括抽污机构，所述抽污机构通过船舶上的拖拽机构与船舶软连接、并由船拖拽向前移动使得抽污口处在淤泥的表层，拖拽机构包括底板、前倾板及抽污仓，所述抽污仓的抽污口处设有刮泥粉碎装置，刮泥粉碎装置包括两个旋转轴，两个旋转轴上分别固定套装有若干滚刀片，两个旋转轴互为反向转动，将表层污泥刮送至抽污仓的抽污口，并将污泥中固体物碾压粉碎。抽真空仓顶部设有抽污泵，由抽污泵启动时的抽负压作用，将淤泥表层半沉降泥浆抽送到船舱里，专门针对对水质危害最大的淤泥表层稀泥浆的清除，以达到改善水质的目的。
