Silt dehydration device and desilting and silt drying ship provided with same

Abstract

The invention relates to a silt dehydration device and a desilting and silt drying ship provided with the same. The silt dehydration device comprises a centrifugal screen, a centrifugal screen rotaryshaft, a filter screen, a spiral material pushing plate and a dehydration motor. The silt dehydration device is provided with a charging inlet and a discharging outlet. The centrifugal screen is connected with the centrifugal screen rotary shaft. The filter screen is in a barrel type and is fixedly connected with the centrifugal screen and matched with the centrifugal screen in a nested mode. Thespiral material pushing plate is arranged in the filter screen and extends in the axial direction of the filter screen. The spiral material pushing plate is located between the charging inlet and thedischarging outlet. The dehydration motor is connected with the centrifugal screen rotary shaft and drives the centrifugal screen rotary shaft to rotate. The centrifugal screen, the filter screen andthe spiral material pushing plate rotate relatively. According to the silt dehydration device disclosed by the embodiment of the invention, by rotating the centrifugal screen with the filter screen, water in silt can be thrown out of the centrifugal screen under the action of centrifugal force, silt can be discharged out of the discharging outlet, thus, the weight and size of silt are greatly reduced, subsequent silt conveying is facilitated, and the desilting efficiency is improved.

Description

technical field [0001] The invention relates to the field of dredging equipment, in particular to a sludge dewatering device and a dredging and drying mud ship equipped with the sludge dewatering device. Background technique [0002] River dredging generally uses mechanical equipment to remove the silt deposited on the bottom of the river to dredge the river. Now people generally use dredging ships to carry out river dredging work. There are many dredging methods for existing dredging ships, such as bucket type, jet suction type, mechanical cutter suction type, hydraulic cutter suction type and rake suction type, etc. . However, after the existing dredging ship collects the silt on board, the silt is not further processed, but the silt is stored in the silt cabin. Because the silt contains a large amount of river water, the silt tank is easy to be filled, causing the dredging ship to dock after working for a period of time to clean out the silt in the silt tank, which seri...

However, after the existing dredging ship collects the silt on board, the silt is not further processed, but the silt is stored in the silt cabin

Due to the large amount of river water contained in the silt, the silt tank is easily filled, and the dredger needs to be docked to clear the silt from the silt tank after working for a period of time, which seriously affects the cleaning efficiency of the silt
