Urban closed river sludge dredging system and method
The invention provides a urban closed river sludge dredging system and method. Pipe holes are arranged at the starting point and the ending point of a cover plate above a dredged river channel section, a movable trolley drives a movable sewage suction pipe to reciprocate in the width direction of a river channel, and sludge with the width where the movable sewage suction pipe is located enters a sludge pipe through the movable sewage suction pipe under the suction force of a sand pump and reaches a water outlet of the sand pump, the sludge enters a filter tank from a diversion trench, water in the sludge enters the bottom of the filter tank through a filter screen, is pumped into a water return pipe by a water return pump and flows back to the river channel, and the sludge left above the filter screen is carried away by a vehicle, so that dry-wet separation of the sludge and the sewage is realized, and the sludge treatment efficiency is improved; and along with the propelling of a desilting process, a rear steel wire rope winch rotates to continuously lengthen a rear steel wire rope, a front steel wire rope winch rotates to continuously shorten a front steel wire rope to pull a trolley track to move forwards, and a sludge pipe winch, an electric wire winch and a water return pipe winch keep rotating synchronously with the rear steel wire rope winch, until the sludge removal work of the river channel section is completed, and therefore full-automatic dredging is realized.
一种城市封闭河道淤泥疏通系统和方法，在疏通河道段上方盖板起点和终点处开设管孔，移动小车带动活动吸污管沿河道宽度方向往复运动，其所在宽度的淤泥在抽沙泵吸力下经活动吸污管进入污泥管，到达抽沙泵出水口处，由导流槽进入滤槽，淤泥中的水分经滤网进入滤槽底部，由回水泵抽入回水管，回流至河道，遗留在滤网上方的淤泥由车辆运走，实现污泥污水干湿分离，提高污泥处理效率；随清淤进程推进，后钢丝绳卷扬机旋转使后钢丝绳不断放长、前钢丝绳卷扬机旋转使前钢丝绳不断缩短拉动小车轨道向前运动，污泥管卷扬机、电线卷扬机和回水管卷扬机与后钢丝绳卷扬机保持同步旋转，直至完成该河道段的淤泥清理工作，实现全自动清淤。
