Environment-friendly overflow barrel equipment of drag suction dredger

Abstract

The invention provides environment-friendly overflow barrel equipment of a drag suction dredger. The environment-friendly overflow barrel equipment comprises an overflow barrel, a hydraulic oil cylinder, a connecting rod structure, a middle connecting rod, a sleeve structure, an environment-friendly valve, a cable frame, a support structure, coaming and a rib plate. The hydraulic oil cylinder is connected with the top of the overflow barrel, the lower end of the hydraulic oil cylinder is connected with the connecting rod structure, the lower end of the connecting rod structure is connected with the middle connecting rod, the sleeve structure is connected with the connecting rod structure, the environment-friendly valve is connected with the middle connecting rod, the cable frame is hingedto one end of the overflow barrel, one end of the support structure is connected with the connecting rod structure through the middle connecting rod, the other end of the support structure is connected with the cable frame, the coaming is arranged on the outer side of the upper end of the connecting rod structure, and the rib plate is connected with one side of the connecting rod structure. The environment-friendly valve comprises an anti-abrasion barrel body, a valve plate, an upper thrust block, a lower thrust block, a valve body structure, a pin shaft structure, a check block, a middle sleeve and a toggle plate. Compared with the traditional technology, abrasion is reduced, the suspension time of stern overflow is shortened, and the effect of protecting the environment is achieved.

Description

technical field [0001] The invention relates to the field of overflow barrel equipment, in particular to environmental protection overflow barrel equipment for trailing suction dredgers. Background technique [0002] With the rapid economic growth and the rapid development of the port transportation industry, new artificial island projects, land reclamation projects, and large waterway projects are constantly emerging, and the demand for dredging market is very strong. Trailing suction dredgers are flexible and efficient. Dredging, loading, and unloading are all done by themselves. The impact on normal navigation is very small, so they are widely used in dredging rivers, reclamation and other projects. During the construction process, the trailing suction dredger uses a centrifugal pump to suck up the mud and sand from the seabed, guide it into the mud tank for sedimentation, and increase the sediment concentration through the overflow device to discharge the excess mud and ...

AI Technical Summary

Problems solved by technology

However, due to the different types of sediment and particle sizes, the sediment particles in the mud tank of the dredger cannot be completely settled.

For fine silt and other small-sized particles that are difficult to settle, the sedimentation effect in the cabin is not good, and the concentration in the cabin is not as expected, and the formed sediment mixture is discharged from the bilge through the overflow tube
