A kind of equipment for improving the loading efficiency of trailing suction dredger

Abstract

The invention relates to a device for improving the loading efficiency of a trailing suction dredger, which is installed in the cabin of the dredger and used to prevent sediment from flowing out of the overflow tube in the cabin, including: an air injection device and a lifting device , the air injection device includes an air pump, an air delivery hose and at least one bubble curtain generating tube, the air delivery hose communicates with the air pump and the bubble curtain generating tube, the air outlet end of the bubble curtain generating tube is arranged toward the overflow cylinder, the lifting device and the bubble curtain generating tube The one-to-one connection can drive the bubble curtain generating tube to move up and down. Implementing the embodiment of the present invention has the following beneficial effects: the air pump can generate a large number of bubbles near the overflow pipe through the bubble curtain generating tube to form a bubble curtain. When the water containing sediment flows toward the overflow pipe, the bubbles prevent the sediment from flowing with the water Continue to move, so that the sediment is kept in the cabin, while the water flows away from the overflow pipe, which greatly reduces the loss of sediment at the overflow tube, and effectively improves the loading efficiency of the dredger.

Description

technical field [0001] The invention relates to the technical field of dredgers, in particular to a device for improving the loading efficiency of a trailing suction dredger. Background technique [0002] The trailing suction dredger is a common equipment used in dredging construction. Its equipped rake head and hydraulic dredging device can excavate and transport the sediment, gravel and other materials on the riverbed or seabed into the cabin, and then remove the soil and gravel Move it to a suitable place to clear the river, widen the river bed, and improve the navigation capacity of the river. [0003] The sediment is excavated from the rake head and transported by the mud pump and pipeline, and then settles in the cabin. As an important link in dredging, the efficiency of loading directly affects the dredging output of the dredger. In the process of loading, the amount of mud Settlement is very critical. In the previous loading process, the mud entered the tank at a hi...

AI Technical Summary

Problems solved by technology

[0004] In view of this, it is necessary to provide a device for improving the loading efficiency of trailing suction dredgers, in order to solve the technical problem in the prior art that muddy water is easy to flow away from the overflow tank and reduce the loading efficiency
