Problems solved by technology

Since the silt in the river now contains a lot of leaves and domestic garbage such as plastic bags and cloth pieces, the filter screen with the above structure will be blocked by these debris in a short time, thus losing the function of water separation

Embodiment Construction

[0025] refer to figure 1 Embodiment one, combining image 3 , Figure 4 , the structure of the underwater river bed is that the upper layer is water, the bottom layer is a hard soil layer, and a soft silt layer is deposited on the hard soil layer. The rear part of the hull of the dredging operation ship is the equipment warehouse, and the high-pressure gas generator and engine used to suck the silt by the jet are installed in the equipment warehouse. The front part of the hull is the mud bin, and the bin mouth 2 of the mud bin is open. shape for easy cleaning and unloading. The upper middle part of the hull is equipped with a gravity energy mud-water separation device 3, and the cockpit 8, the dredging pipe lifting device and the high-pressure air pipe expansion device 6 are located at the rear of the hull; the high-pressure air pipe 5 communicates with the high-pressure gas generator, and the injection end passes through the The high-pressure air pipe expansion device 6 is...

Abstract

The invention discloses a desilting operation ship. A ship body is provided with a high-pressure air generator for sucking silt through jet, and is also provided with a gravitational energy mud-waterseparation device, a mud sucking pipe lifting device and a high-pressure air pipe extension device; an intake pipe of a high-pressure air pipe communicates with the high-pressure air generator, and aspraying end is upwards inclined underwater by the high-pressure air pipe extension device to extend into a pipe at the lower end of the mud sucking pipe for fixation; the mud sucking pipe is vertically mounted at the tail part of the ship body; an outlet end of the mud sucking pipe communicates with an inlet of the gravitational energy mud-water separation device; and the gravitational energy mud-water separation device feeds leached silt to a silt bin. The water ratio in a mud-water mixture sucked by the desilting operation ship is prominently reduced, so that the bearing efficiency of the silt bin is improved, and the construction efficiency is improved; the mud-water separation device is operated by using dead weight of the sucked silt without additionally arranging a power device; andin particular, the desilting operation ship is suitable for the water quality purifying engineering of such natural water as vast river channels, lakes and reservoirs.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a dredging operation ship for removing mud from the bottom of river courses, lakes and reservoirs. Background technique [0002] The water quality of my country's rivers, rivers, lakes, reservoirs and other natural waters and drinking water sources is deteriorating day by day, and urgently needs to be treated. Generally, the bottom of the water is composed of a hard soil layer and a soft silt layer deposited on it. According to the requirements of ecological dredging, only the soft silt layer containing a large amount of pollutants at the bottom of the water should be removed without damaging the underwater ecological environment. In order to remove soft silt at the bottom of the water and improve water quality, Chinese patent ZL 201210133667.X introduces a mud suction / sand boat powered by an air suction and discharge pump. The suction and discharge p...
