Problems solved by technology

As one of the key equipment used in the solidification process of waste mud, stirring and curing equipment often uses general-purpose stirring equipment, which cannot automatically and accurately control the mixing ratio between waste mud and curing agent. It is necessary to mix the waste mud and curing agent in proportion After mixing, put it into the mixing equipment for stirring, which is inefficient, and it is easy to mix unevenly due to the concentration of curing agent, which will affect the curing effect

Abstract

The invention discloses an engineering spoil on-site stirring and solidifying device which comprises a machine shell, a spraying device and a stirring device; an opening for feeding is formed in one side of the machine shell, and a conveying device is arranged at the position, close to the opening, in the machine shell; the spraying device is arranged above the machine shell, the spraying device comprises a liquid storage tank, a metering pump and a nozzle which are sequentially connected, and the nozzle extends into the machine shell and faces the position over the conveying device; the stirring device is arranged in the machine shell, the stirring device comprises a stirring bin and a stirring shaft, the upper portion of the stirring bin communicates with a feeding hopper, and the feeding hopper is connected with the tail end of a transmission device; and a discharging pipe is connected to the lower part of the stirring bin and extends to the outer part of the machine shell. The mixing proportion of waste slurry and a curing agent can be automatically and accurately controlled, and then the waste slurry and the curing agent enter the stirring bin to be stirred, so that the curing agent is further uniformly mixed with the waste slurry.

Description

technical field [0001] The invention relates to the technical field of solidification devices for waste engineering mud. More specifically, the invention relates to an in-situ stirring and solidifying device for engineering spoil. Background technique [0002] With the rapid advancement of my country's urbanization process, infrastructure such as urban transportation is developing into underground space, and a large number of abandoned projects will inevitably be generated during the construction of various types of infrastructure such as underground diaphragm walls, bored piles, and shield tunneling projects. The output of mud has increased rapidly, and the environmental and social problems caused by construction mud have gradually attracted great attention. [0003] The existing treatment methods for waste mud mainly include natural stacking and drying and solidification treatment. Natural stacking and drying is to transport the waste mud to the suburbs for natural drying....
