Rapid dehydration device for mud with high water content

Abstract

The invention provides a rapid dehydration device for mud with a high water content. The rapid dehydration device comprises a muddy water storage component, a mud inlet component, a liquid level measurement component, an inlet mud control component, an electric osmosis component, a conveying support component, a conveying component, a water absorption component, a mud scraping component, a mud receiving component, a dehydration component and a water receiving component. When muddy water moves to the top end of the device along with the conveying component, mud on the surface of a water absorption belt is scraped away through the mud scraping component, while the scraped mud falls into the mud receiving component; the water absorption component is extruded with the dehydration component after scraping of the mud, so as to remove moisture in the water absorption component, while the extruded water falls into the water receiving component. The rapid dehydration device has the advantages that the discharging efficiency is improved; the mud dehydration efficiency is improved remarkably.

Description

technical field [0001] The invention relates to a device in the technical field of water conservancy engineering and water environment protection engineering, in particular to a rapid dehydration device for high-water slurry. Background technique [0002] Land reclamation is an important way to solve the shortage of land resources in our country. In the next ten years, my country will use dredging fill for tidal flat reclamation on a larger scale. In the dredging and reclamation construction, the moisture content in the early stage is very high, how to reduce the moisture content of the dredging fill is a key task in the foundation treatment of the dredging reclamation area. The moisture content of the soil determines the bearing capacity of the foundation of the reclamation area. At present, the method of vacuum preloading and rapid drainage consolidation is mainly used for drainage treatment of dredged fill foundation. The energy consumption of this method is large, the...

Problems solved by technology

[0004] Chinese patent number: CN 200610060194.X, publication (announcement) number: CN1837109, name: a squeeze type mud dehydration device, the main disadvantages of this technology are: 1) due to the high pressure, the reciprocating filter plate is easily damaged; 2) The filtration efficiency of the filter is low, and it is easy to be blocked by filter mud; 3) The processing capacity is limited

[0005] Chinese patent number: CN01812300.7, the patent name is: Equipment and method for rapid dehydration of mud. This invention discloses a system and method for dehydrating continuous mud flow at high flow rates. The main disadvantage of this patent is that : 1) The mud treatment capacity is low, so it is not suitable for the treatment of dredging fill in land reclamation projects

2) The filtration efficiency of the filter is low, and it is easy to be blocked by filter mud

3) Need to add flocculant, high cost

[0006] Chinese patent number: CN 200680052627.5, publication (announcement) number: CN101384326, patent name: vibrating separator, its shortcoming is mainly that it is not suitable for the dehydration treatment of high water content mud, and at the same time, this kind of mechanical vibration is not only easy to wear the screen , and the energy loss is large

Its shortcomings mainly lie in: 1) It is not suitable for the dehydration treatment of mud with high water content; 2) It needs to add flocculant, which is costly; 3) The slag outlet is easy to block, otherwise the water content of the mud is high; Vibration of the entire equipment is induced during work, which not only reduces the life of the equipment, but also consumes a lot of energy
