Background
For soil, particularly soil polluted by heavy metal, the soil can not be used as a soil matrix for crop growth any more, the main reason is that crops absorb heavy metal ions in the soil, and after people and livestock eat the crops, the content of the heavy metal ions in the body can be obviously increased, so that the health of human bodies is influenced, therefore, the composite passivator is scattered into the soil, the heavy metal ions are promoted to react with the passivator, a substance form which is difficult to absorb by plants is formed, and the aim of purifying the soil is achieved; the content ranges of zeolite, activated carbon and fly ash in the existing composite passivator are 3: 1: 1 (mass ratio) and has the functions that the zeolite is a porous aluminosilicate mineral with an anionic framework silicate structure, has larger specific surface area and high cation exchange capacity, and has strong adsorption capacity and ion exchange function on heavy metals; the active carbon has the characteristics of larger porosity, rich active functional groups and high cation exchange capacity, and also has very strong adsorption capacity and complexation on heavy metals; the zeolite and the activated carbon have good adsorbability on nutrient elements N, P and K and strong fertilizer-keeping capacity, and are environment-friendly materials, and the fly ash has large specific surface area, pH value and clay content; has better adsorption capacity to heavy metals and other nutrient elements.
When the composite passivator is prepared, a plurality of raw materials (zeolite, activated carbon and fly ash) need to be mixed to form the passivator, so that mixing equipment is needed, most of the existing mixing equipment is simply stirred and mixed through a stirring box, and the composite passivator has the following defects:
1. the stirring device has the defect that bidirectional rotation stirring is inconvenient, (most stirring devices are single to control the transverse rotation of the stirring shaft, and the passivating agents are granular powder which are different from water and are difficult to be quickly and uniformly mixed, so that the mixing effect is poor and the mixing efficiency is low);
2. the device has the defect that the entering raw materials are inconvenient to continuously and uniformly crush, (more blocky raw materials exist during mixing, so that the mixing is not uniform, and the using effect is influenced);
3. the stirring device has the defect that uniform stirring is inconvenient to move, (most of the stirring devices need to take out the formed passivator after mixing, and then manually stir materials independently).
In order to solve the problems that bidirectional rotary stirring, continuous uniform crushing and moving uniform stirring of raw materials are inconvenient, a mixing device for preparing a heavy metal contaminated soil composite passivator and a using method are provided.
