Sand grain and liquid filtering device for sand excavating ship

Abstract

The invention discloses a sand grain and liquid filtering device for a sand excavating ship. The device comprises a bottom support base plate and a columnar hollow shell, wherein an electromotor mounting shell is fixed, through a bolt, at the center of the upper surface of the bottom support base plate; an electromotor is mounted inside the electromotor mounting shell; support legs are mounted onboth sides of the upper surface of the bottom support base plate. Working based on the object gravity and the spiral feeding principle, the device disclosed by the invention can perform effective andpersistent filtration on sediment and liquid; with a conical sewage dispersing mechanism, the device can protect the electromotor at the bottom and automatically disperse the falling liquid under theeffect of centrifugal force through quick rotation so as to improve the practicability; moreover, with a pressure type sediment flow control mechanism, the device enables the sediment to flow normallyonly when the rated pressure is reached, then the sewage in the sediment is compressed and discharged, and thus the filtering effect is improved.

Description

technical field [0001] The invention relates to the technical field of dredging ship equipment, in particular to a sand and liquid filtering device for a dredging ship. Background technique [0002] At present, in the sand dredger, an indispensable piece of equipment is the filter device between the sand and the liquid. Its main function is to remove the liquid and sand from the suctioned mixture when it enters the filter device. Separation, while the general filter structure is too simple, and the filtering effect is not obvious. Contents of the invention [0003] The object of the present invention is to provide a sand and liquid filtering device for dredging ships, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a sand and liquid filter device for dredging ships, comprising a bottom support base plate and a cylindrical hollow...
