Abstract

The invention belongs to the technical field of environmental geotechnics and particularly relates to a quick dewatering and solidifying apparatus for river sludge, comprising an upper screening and solidifying deice and a lower storage and drying device connected with the same. The screening and solidifying device includes a filter barrel; the filter barrel is of hollow cylindrical structure andincludes a feed port and a discharge port; a strainer is arranged in the filter barrel; the sidewall of the filter barrel is provided with air holes communicated with the inside of the filter barrel;the feed port is communicated with the discharge port via the strainer; the discharge port is communicated with the lower storage and drying device. The quick dewatering and solidifying apparatus forriver sludge has good solidifying effect, short solidifying cycle, good construction simplicity, low cost and good environmental friendliness, and is easy to popularize within a large range, and a feasible scheme is provided for quickening the fundamental construction and economic development of China.

Description

technical field [0001] The invention belongs to the technical field of environmental geotechnical engineering, and relates to a rapid dehydration and solidification device for river silt, in particular to a device for obtaining silt soil with no large particle impurities and high solidification strength by using the fluidity of high water content silt soil through a screening system Curing device. Background technique [0002] Silt is a flocculent and honeycomb structure formed by the deposition of fine particles such as clay minerals under the action of intergranular electrostatic force and molecular gravity in slow flowing water environments such as ocean or lake areas. Sludge is a kind of engineering waste soil with high water content. Its water content is mostly 1.2 to 2.0 times of the liquid limit water content. It is in a flowing state and has almost no strength, so it cannot be used directly for engineering. [0003] my country has a vast land and abundant resources,...
