Rapid drainage solidification unit for bottom mud generated in river and lake dredging

Abstract

The invention discloses a rapid drainage solidification unit for bottom mud generated in river and lake dredging. The rapid drainage solidification unit comprises a bottom mud accommodating body which is of a hollow structure, wherein one end of the hollow structure is provided with an opening; a cabin door is arranged at the open end of the bottom mud accommodating body; one side of the cabin door is rotationally connected to the bottom mud accommodating body through a rotating shaft; the upper end of the bottom mud accommodating body is provided with two mud filling holes; an exhausting fan is mounted between the mud filling holes; a bearing plate is arranged in the inner chamber of the bottom mud accommodating body. According to the rapid drainage solidification unit disclosed by the invention, the bearing plate and super-strong woven cloth both have water permeability; slurry is retained on the bearing plate, water permeates the bearing plate and reaches a position below the bearing plate, and the water is drained out of the rapid drainage solidification unit through vacuum water pumping; a heating rod is used for heating the bottom mud so that accumulation of water inside the rapid drainage solidification unit is reduced, and the solidification speed of the bottom mud is quickened as well; after the bottom mud is solidified completely, the cabin door is opened to pull out the bearing plate by using a pulling device, the solidified bottom mud is conveyed to an other place, and the rapid drainage solidification unit is also capable of performing subsequent bottom mud solidification work.

Description

technical field [0001] The invention relates to the technical field of bottom mud treatment, in particular to a rapid drainage and consolidation device for dredging bottom mud of rivers and lakes. Background technique [0002] The water pollution of rivers and lakes in our country is serious, and large-scale river and lake sediment dredging is required every year, which inevitably produces a large amount of dredged river and lake sediment that needs to be treated. According to the "Overall Plan for Comprehensive Treatment of Water Environment in Taihu Lake Basin" (2008), only the comprehensive improvement project of East Taihu Lake needs to dredge up to 18 million m3 of sediment. In addition, there are as many as 1,000 rivers and 3,574 kilometers of dredged rivers in the Taihu Lake area of ​​Jiangsu Province. The total amount of dredging reached 60 million m3. It can be seen that in the future, the dredged sediment of rivers and lakes in my country will be considerable, and...

Problems solved by technology

[0003] However, due to the large amount of river sediment treatment projects in our country every year, the traditional sediment consolidation devices have defects such as low efficiency, inconvenient use, non-reusable use, and high cost, which have been unable to apply to the river sediment treatment work in our country. Design a rapid drainage and consolidation device for dredging sediment in rivers and lakes to solve the above problems
