Benefits of technology

The patent describes a device for dredging that reduces the amount of water needed and saves energy by using a side inlet that causes swirl in the suction head, resulting in a higher sand share in the mixture when it exits the outlet. The device also uses a jet water device that introduces a flow into the side inlet, which further enhances the effect of the lateral flow. This results in a more efficient and cost-effective device for dredging.

Problems solved by technology

This known device requires a high number of parts and is relatively complex for increase the sludge contents.

Embodiment Construction

[0040]The invention will further be elucidated referring to all FIGS. 1-3. Fig. shows a suction head 1 for a dredger. Such a suction head 1 is dragged by a dredger along the sand bed 5 to be sucked away. The suction head 1 comprises an outlet 2 for fluidly coupling the suction head 1 with a suction tube 3 for transport of dredge to the loading space of a floating dredger, which loading space and dredger are not shown. The suction tube 3 usually extends in the dragging direction 24 of the suction head 1 as is shown here.

[0041]The suction head 1 comprises a sand inlet 4. In use, this inlet 4 in use faces a sand bed 5 to be sucked away. In FIG. 1 the inlet 4 and the top face of the sand bed 5 coincide however this coinciding is not strictly required as is clear from FIGS. 2 and 3 wherein the inlet 4 and the top face of the sand bed 5 do not coincide however the inlet 4 still faces a sand bed 5 to be sucked away. The inlet 4 takes in a flow of dredge 6 in the suction head 1. The flow of...

Abstract

A suction head (1) for a dredger, includes;—an outlet (2) for fluidly coupling the suction head with a suction tube (3) for transport of dredge to the loading space of a floating dredger;—a sand inlet (4), which in use faces a sand bed (5) to be sucked away, for taking in a flow of dredge (6) in the suction head, and which flow of dredge runs in a dredge flow direction (7) at the sand inlet;—a side inlet (8) fluidly coupled with the sand inlet, wherein the side inlet and the outlet are arranged at opposite sides of the suction head for introducing a lateral flow (9) from outside the suction head into the suction head locally at the sand inlet, which lateral flow runs substantially transverse relative to the dredge flow direction.

Description

BACKGROUND[0001]The present invention relates to a suction head for a dredger, such a suction head having;[0002]an outlet for fluidly coupling the suction head with a suction tube for transport of dredge to the loading space of a floating dredger, and a[0003]a sand inlet, which in use faces a sand bed to be sucked away, for taking in a flow of dredge in the suction head, and which flow of dredge runs in a dredge flow direction at the sand inlet.[0004]JP61028635 A discloses a suction head device for sludge dredging work. The device has a rotator with a screw blade provided along an opening in the bottom of the body to permit dredging work with high sludge contents. This known device requires a high number of parts and is relatively complex for increase the sludge contents.[0005]FR834639 (A) disclose a suction head for a trailing dredger. FR834639 aims to perform dredging of very permeable soils with a high concentration. Therefore, the draghead is traversed by a convergent nozzle dir...
