Description
Technical field
The present invention relates to a kind of uniform humidification devices of clay, are widely used in civil engineering, geotechnical engineering, radiochemistry etc.
Research field.
Background technique
The clay materials such as bentonite have extremely low permeance property, stronger water swellability and higher plastic limit, are to put
Important buffering/backfilling material in the fields such as injectivity waste disposition, geotechnical engineering, hydraulic engineering.In engineer application, usually will
Certain moisture is added in clay material, and the humidifying of the soil body is carried out by the liquid-solid method directly mixed, although this method has
Have the characteristics that easy to operate, but due to the extremely strong plasticity of the materials such as bentonite, causes to cannot achieve in the direct mixed process of soil-water
Uniform humidifying, humidifying sample often exist moisture content, dry density and aggregation size homogenization degree it is lower, the soil body largely adheres to
In prepare container side the problems such as.According to centrifugal modeling standard, soil can be improved to a certain extent using the method stood overnight
The homogeneity of body porous media, but actual effect is not significant.Therefore, soil-water direct mixing method inevitably results in humidifying
Difference on soil body physics and engineering properties.At the same time, in the research fields such as nuclear environment science nuclein migration, to humidifying soil
More stringent requirements are proposed for the homogeneity of body, and homogeneity standard is improved with the reduction of sample scale.
Currently, being directed to clay humidifying, the method still mainly directly mixed using soil-water, laboratory mostly uses spray-on process pair
A small amount of clay is slowly added water and stirred.But this method is difficult to meet the requirement in the short time, mixing and stirring a large amount of soil bodys, and nothing
Method overcomes the problems, such as that moisture distribution is uneven in soil-water mixed process, will generate a large amount of spherical agglomeration body.Kobayashi etc.
Propose the method for using and being added in clay in the form of the solid ice powder of water and carrying out mixing preparation, it is believed that utilize solid-solid blend
Homogeneity is far longer than solid-liquid hybrid mode, can effectively reduce aggregate structure, improves the homogeneity of moisture distribution.For
This technology, it is studied by domestic only Lanzhou University at present, but does not research and develop relevant humidification device, mainly takes
Ice powder preparation-ice powder transfer-soil match-maker's work hybrid manipulation is successively carried out in -25 DEG C of low temperature chambers, should pass through ice crusher in the process
It is loaded down with trivial details to prepare ice powder process, low temperature chamber is built and ice powder preparation link input cost height, personnel's safe operation risk are big and artificial
The uniformity mixed and stirred can not effectively be controlled.In view of the above problems, needing a kind of integration in current experiment research and engineer operation
, can synchronize realize ice crystal preparation and low temperature stirring clay humidification device.
