Abstract: The present disclosure discloses a temperature-controllable large-size geotechnique true triaxial multi-field coupling test system and a test method. The system includes a host loading mechanism, a deformable large-size soil box, an independent three-dimensional loading unit, a refrigeration, water and salt supplementation unit, and a soil-water-ice-salt change monitoring unit. The deformable large-size soil box is arranged on the host loading mechanism. In combination with the special structural design, monitoring is carried out by dividing a large-size soil test sample into environmental soil and a core soil region to eliminate the size effect of the test. The solution can simulate a three-dimensional stress state of the soil test sample in a three-dimensional open system. In consideration of the evolution of hydrothermal salt and three-dimensional migration of temperature, water, salt, etc. between the soil and the environment, temperature-water-salt-stress-strain multi-field coupling is realized.

Abstract: The present invention discloses a same-cavity integrated vertical high-speed multistage superfine pulverizing device and method for walnut shells. The same-cavity integrated vertical high-speed multistage superfine pulverizing device for walnut shells includes a double-channel sliding type feeding device and a same-cavity integrated vertical pulverizing device. The same-cavity integrated vertical pulverizing device includes a material lifting disc and a same-cavity integrated vertical pulverizing barrel. A first-stage coarse crushing region, a second-stage fine crushing region, a third-stage pneumatic impact micro pulverizing region and a fourth-stage airflow mill superfine pulverizing region are disposed in the same-cavity integrated vertical pulverizing barrel. Walnut shells falling through the double-channel sliding type feeding device are uniformly lifted by the material lifting disc to a wedge-shaped gap of the first-stage coarse crushing region to be coarsely crushed, and coarsely crushed materials are finely crushed by the second-stage fine crushing region through a two-stage wedge-shaped direct-through gradually reducing gap. The third-stage pneumatic impact micro pulverizing region performs high-speed collision on finely crushed walnut shell particles, and walnut shell fine particles are carried by a high-speed airflow and are collided and violently rubbed to be pulverized. The microparticle grading is realized by the fourth-stage airflow mill superfine pulverizing region by using arc-shaped blades, and microparticles conforming to a particle size condition are attracted out through negative pressure attraction.
