In situ sludge solidifying mixer and working method thereof

Abstract

The invention provides an in-situ silt solidification and agitation machine and a working method thereof, relating to the technical field of hydraulic excavator, in particular to the technical field of meliorative treatment of the dredging silt generated in water conservation and water environment treatment projects. The invention comprises a connecting part I and an agitating part II, which are connected by a connecting component; the connecting part I comprises an oil inlet pipeline, an oil return pipeline and a connecting pivot pin hole; the agitating part II comprises agitating teeth, a hydraulic motor, an agitating shaft, a driving gear of the hydraulic motor, a driving chain, an agitating shaft gear and a solidification material sprayer; the oil inlet pipeline and the oil return pipeline respectively penetrates and are arranged on the connecting component and connected with the hydraulic motor, one end of the connecting component closer to the connecting part I is provided with a longitudinal fixing component which is connected with the connecting pivot pin hole; the end of the hydraulic motor is connected with the driving gear of the hydraulic motor, the motor gear is connected with the agitating shaft gear positioned in the middle part of the agitating shaft by the driving chain and the agitating shaft is connected with the agitating teeth; the connecting component is provided with the top of the solidification material sprayer in a penetrating way. The invention realizes the aims of low process cost, high efficiency and convenient and flexible operation.

Description

technical field [0001] The invention relates to the technical field of hydraulic mixers, in particular to the technical field of improving the dredging sludge produced in water conservancy and water environment treatment projects. Background technique [0002] In my country's water conservancy and water environment treatment projects, a large amount of dredging silt is produced every year. It is estimated that in recent years, the annual dredging volume in Jiangsu Province has reached 50 million cubic meters, and the annual dredging volume in the Pearl River Delta region has reached 80 million cubic meters. The amount of dredging required due to serious pollution reached 25.12-34.48 million cubic meters. The treatment of dredged silt is usually based on requisitioned land and piled up. Taking Taihu Lake as an example, if all the sediment is dredged and excavated, it will need to occupy an area of ​​8.4 to 11.5 square kilometers if it is stacked at a filling height of 3 meters...

AI Technical Summary

Problems solved by technology

[0004] In the construction of solidification treatment of sludge, a sludge solidification treatment machine (such as patent: ZL200420028026.9) is usually used for solidification and mixing construction. car, the processing efficiency per hour is only 100-150 cubic meters of sludge

Moreover, the fixed investment cost of the sludge solidification treatment machine is relatively high, which greatly limits the efficiency of sludge solidification treatment.
