Description
Technical Field
The invention relates to the technical field of stirring devices, in particular to a bidirectional variable-section fly ash cement soil stirring device.
Background
At present, two methods of medicament stabilization and cement solidification are common for innocent treatment of the fly ash from domestic waste incineration at home and abroad. The chemical stabilization method is a process of converting harmful substances in fly ash into soluble substances with low toxicity and low mobility by chemical agents. However, the chemical stabilization process generates high-concentration inorganic salt wastewater, which requires additional cost for subsequent treatment, and more seriously, the fly ash treated by chemical agents still has dioxin leaching. The cement curing method has simple operation flow and is economical and practical, but the capacity increase amount of the cured cement is large, and a large amount of resources are wasted due to direct landfill.
Because the components of the fly ash after the garbage incineration are very similar to those of the fly ash, the fly ash is subjected to primary stabilization treatment and then is further solidified by combining cement, and finally the novel fly ash cement soil mixing pile is formed. The fly ash cement soil mixing pile is formed by mixing fly ash, cement and soil in a certain proportion through a special mechanical device. The fly ash cement soil mixing pile is a new means for harmless treatment of waste incineration residues, can realize reduction, harmlessness and resource utilization of household waste incineration fly ash, realizes 'changing waste into valuable', not only lightens the load of a waste landfill and reduces the environmental pressure, but also has remarkable social and environmental benefits.
Disclosure of Invention
In order to solve the technical problems, the invention provides the bidirectional variable-section fly ash cement soil stirring device which is simple in structure and convenient to use.
In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a two-way variable cross section flying dust soil cement agitating unit, includes first whitewashing mouth, second whitewashing mouth, drill bit, flexible node, stirring vane, interior stirring drilling rod and outer stirring drilling rod, agitating unit is equipped with interior stirring drilling rod and the outer stirring drilling rod that carries out clockwise, anticlockwise rotation simultaneously, and interior stirring drilling rod is equipped with first whitewashing mouth and second whitewashing mouth, and first whitewashing mouth and second whitewashing mouth are connected with the whitewashing union coupling of cement thick liquid and flying dust cement thick liquid respectively, and the drill bit is connected with interior stirring drilling rod bottom, and flexible node is established at the stirring vane middle part, and flexible node can make stirring vane freely stretch out and draw back the transform pile footpath, and interior stirring drilling rod is arranged in the outer stirring drilling rod, and interior stirring drilling rod and outer stirring drilling rod can carry out clockwise, anticlockwise rotation simultaneously.
The stirring blades are two telescopic groups of stirring blades which are arranged in a cross shape.
Stirring blades are respectively arranged on the inner stirring drill rod and the outer stirring drill rod, the stirring blades are bidirectional variable-section stirring blades, slurry can be controlled between the two groups of stirring blades, so that the fly ash cement slurry and the broken soil body are fully mixed and stirred, the slurry is effectively prevented from upwards overflowing, and the fly ash cement soil stirring material is finally formed after the soil body is uniformly mixed.
The bidirectional variable-section stirring blades are characterized in that two groups of stirring blades are respectively installed in the clockwise direction and the anticlockwise direction.
The invention has the outstanding effects that:
1. because two different slurry spouting ports are arranged for spouting and stirring, the working efficiency can be improved and the environment pollution caused by fly ash can be avoided.
2. Because stirring vane can stretch out and draw back wantonly, conveniently change different stake footpaths.
3. Because the inner stirring drill rod 6 and the outer stirring drill rod 7 can rotate clockwise and anticlockwise at the same time, the cement slurry can be controlled between the two groups of stirring blades, so that the fly ash cement slurry and the broken soil body are fully mixed and stirred, the slurry is effectively prevented from upwards overflowing, and finally the fly ash cement slurry uniformly mixed soil body is formed.
