Coupling type strong crushing agitator capable of using for soil remediation

Abstract

The invention discloses a coupling type strong crushing agitator capable of using for soil remediation. The crushing agitator comprises anagitator head, anagitator arm, a transmission system and a control and travel system. The agitator head comprises a left agitator branchhead, a right agitator branchhead, anintermediate agitator branchhead, a transverse rotating support shaft, and a longitudinalrotating main shaft. The agitator armcomprises an agitator lower arm and an agitator upper arm, the agitator lower armcomprises nozzles, a photosensitive belt, a lower transition device, an upper transition device, a multiple catheter and an agitating track, the agitator upper arm comprises a water storage tank, a first intermediate water tank, a water diversion tank, and a second intermediate water tank. According to the strong crushing agitator, a structure design is novel, a stirring range is larger, stirring timesare reduced, stirring uniformity, maneuverability and suitability for different sites are increased, each nozzle is designed ingeniously for adding agent conveniently, controlling soil moisture and prolonging a service life of equipment, each detail of the agitator is designed creatively, and so that operation is convenient, a function is stronger and practicability is provided, and the promotion is convenient.

Description

technical field [0001] The invention relates to the technical field of soil remediation agitators, in particular to a coupled powerful crushing agitator that can be used for soil remediation. Background technique [0002] Early soil pollution is concealed, persistent and harmful. According to statistics, 36 million hectares of farmland has been polluted by organic pollutants nationwide. The types of pollutants include petroleum, polycyclic aromatic hydrocarbons, pesticides, organic chlorine, etc.; The area of ​​land seriously polluted by oil has reached 10,000 hectares, and the petroleum refining industry has also polluted a large area of ​​land. The land contaminated by heavy metals in the country has reached 20 million hectares, of which more than 700,000 hectares have been seriously polluted. Soil pollution remediation is imminent. The principles of contaminated soil remediation technology can include: (1) changing the form of pollutants in the soil or the way they combi...

AI Technical Summary

Problems solved by technology

Contaminated soil remediation technologies mainly include thermal desorption, leaching, incineration, chemical oxidation, and biological remediation, and the remediation methods are divided into in-situ and ex-situ. Among them, the in-situ chemical oxidation remediation technology is easy to operate and can avoid secondary Pollution can be achieved by adding chemicals and mixing them with the soil. There are two key points in this technology. First, the internal chemical formula and ratio; second, the external mechanical stirring device, and the current stirring device is too simple and rough. The mixing form is too single, the mixing is uneven, the mixing efficiency is limited, and it cannot meet the requirements of complex site conditions, etc.
