River mud dehydration and recovery device

Abstract

The invention discloses a river mud dehydration and recovery device which comprises a mixing chamber, transport cavities, a ventilating centrifugal machine and a base, wherein the transport cavities are located at the lower part of the mixing chamber; the transport cavities are arranged at the left side and right side of the lower end of the mixing chamber; a bottom fixing frame is arranged at the bottom end of each transport cavity; the bottom of each bottom fixing frame is provided with a transport motor; the top end of each transport motor is provided with a spiral transport shaft; the top end of each transport cavity is provided with a feeding cavity; each spiral transport shaft runs through the corresponding whole transport cavity and the tail end is located in the feeding cavity; a drain pipe is arranged at the bottom end of each transport cavity; a top fixing frame is arranged at the bottom end of the mixing chamber; a mixing motor is arranged at the upper end of the top fixing frame; a mixing rotating shaft is arranged at the bottom end of the mixing motor; and a mixing frame is arranged at the bottom end of the mixing rotating shaft. The river mud dehydration and recovery device has the beneficial effects that the dehydration efficiency is fully improved, the dehydration quality is improved, and meanwhile, nutrient substances in the mud are separated from impurities.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a device for dehydrating and recovering river sludge. Background technique [0002] In the south of the Yangtze River in my country, especially in the southeast coastal area, due to the high groundwater level and complex geological structure, public, industrial and civil buildings generally use pile foundations as building foundations. During the construction of pile foundations, a large amount of construction mud is produced (each Cubic natural soil can produce 4 to 5 cubic mud, and each foundation project usually produces thousands or even hundreds of thousands of cubic mud), with the continuous acceleration of urbanization, high-rise, super high-rise buildings, subways, expressways, large bridges There are more and more constructions such as various projects, and the amount of mud produced is also increasing. If not handled properly, it will cause environmental pollution and waste of reso...

AI Technical Summary

Problems solved by technology

Commonly used dewatering machines include belt filter press, plate and frame filter press, vacuum filter and screw press dehydrator, etc.; the main problem of the existing technology is that the moisture content of dewatered sludge is high, and the effect of sludge reduction is not obvious ;At the same time, the sludge not only contains various sundries, but also contains quite a lot of nutrients. The sludge is a kind of natural fertilizer. The current sludge treatment method does not fully utilize the value of the sludge
