Waste slurry curing device and slurry curing method

Abstract

The waste slurry curing device comprises a water collecting tank, a connecting pile is fixedly connected to the bottom of the inner wall of the water collecting tank, a water seepage pond is fixedly connected to the end, away from the water collecting tank, of the connecting pile, a pump machine is arranged on one side of the bottom of the water seepage pond, and the output end of the pump machine is connected with a conveying pipe; a water seepage tank is arranged in the pump body, a conveying pipe is arranged in the pump body, a stirring barrel is arranged at the end, away from the pump body, of the conveying pipe, the bottom of the stirring barrel communicates with a connecting pipe, and the water seepage tank is formed by cement, sand, slag and fly ash through high pressure. According to the slurry curing device, the slurry starts to be cured, in the curing process, excessive water can be rapidly spin-dried and removed through the dehydration assembly, so that the curing speed of the slurry is increased, compared with the traditional technology, the efficiency is higher, and more slurry is cured in unit time.

Description

technical field [0001] The invention relates to the technical field of waste mud treatment, in particular to a waste mud solidification device and a mud solidification method. Background technique [0002] The engineering mud needs to be discarded after the construction is completed or after it fails to meet the requirements for use. At present, the existing treatment methods of engineering waste mud are out-of-tank transportation, on-site precipitation drying and traditional vacuum pre-pressing treatment. Due to the large output of engineering mud and high water content, about 75% of the actual transported out is water, which has high processing cost and low efficiency. In the process of outbound transportation of mud, there are often spills, which are likely to cause environmental pollution. At present, tank trucks and muck trucks are prohibited from passing through main roads in most cities, which brings great inconvenience to outbound transportation. [0003] In the pr...

Problems solved by technology

In the way of mud transportation, due to the large output of engineering mud and high water content, about 75% of the actual transportation is water, and the treatment cost is high and the efficiency is low.

In the process of mud transportation, there are often spills and leaks, which are likely to cause environmental pollution. At present, the main roads of most cities prohibit the passage of tank trucks and muck trucks, which brings great inconvenience to Sinotrans.

[0003] In the existing technology, the method of solidifying mud is used to reduce the volume of mud during transportation, but the existing mud curing treatment takes a long time and the curing efficiency is low, which cannot meet the solidification requirements of waste mud generated by some large projects.
