The sand suction ship, also known as the sand suction ship, takes the sand suction pump as the main component to take sand, sucks up the underwater river sand or sludge by the suction of the sand suction pump, and then discharges it to the designated position through the upper sand discharge pipe.
Sand suction boats can be subdivided into several types, including small shore boats, jet sand suction boats, self-pumping and self-unloading boats, and sand suction boats during drilling, which are customized according to the situation. Jet suction sand dredger is one of the most widely used sand dredgers at present.
The invention has novel design, simple operation and high efficiency, and is suitable for river dredging, lake and reservoir dredging, reclamation, port and dock cleaning and sand pumping. The equipment consists of hull, conveying system, water inlet system and emptying system. The conveying system includes power, clutch, mud pump, etc. The evacuation system includes high-pressure water pump and vacuum pump device.
Structure and principle of sand dredger;
The machinery of sand pumping ship consists of six parts: hull, sand pumping pump, diesel engine, slurry hanging machine, rubber hose and anchor. Sand dredgers are divided into: 15-40, 60-80, 80- 100,120, 120- 150,/kloc.
Ordinary sand dredgers can extract and screen sand from the depth of 3- 15 meters underwater every hour. The cabin is divided into three bodies, with floating bodies at both ends and a sand cabin in the middle. Walking speed 15km/ h, slurry hanging machine driven by diesel engine.
After the sand pumping boat travels to the destination, the sand is pumped to the middle cabin by a sand pumping pump and washed by a water gun, and the sand is quickly pumped to the middle cabin. After full load, drive the boat to the shore, stir the turbine reducer, open the bottom door of the boat to let the sand leak to the dock, and then pump the sand to the dock with the balancing boat.
