A mixer suitable for 3D molding of large complex geological models

Abstract

A mixer suitable for 3D molding of large and complex geological models, including a mixing component, a feeding component, a water supply component, a similar material storage and weighing component, an admixture storage and weighing component, a dust removal component, a filter component and a discharge component; The feeding component inputs similar materials into the mixing component through the similar material storage and weighing component. The water supply component is used to input clean water into the mixing component. The admixture storage and weighing component is used to input admixtures into the mixing component. The dust removal component is used In order to remove floating dust generated during the preparation of similar materials, the filter component is used to remove particles with excessive particle sizes in similar materials, and the discharge component is used to transport the mixed similar materials to the print head of the 3D molding machine. The mixer adopts an overall sealing design and has a dust removal function to avoid the generation of floating dust during the mixing process; the feeding and mixing are fully automated; it has a filtering function during the mixing process of similar materials, which can remove particles with excessive particle size from similar materials and avoid printing heads. block.

Description

technical field

[0001] The invention belongs to the technical field of preparing large-scale three-dimensional physical models, in particular to a mixer suitable for 3D forming of large-scale complex geological models. Background technique

[0002] Simulating the excavation process of natural rock mass engineering through physical model tests is an important method for predicting and forecasting large-scale rock mass engineering geological disasters. The geological model needs to be made of similar rock mass materials, and the similar rock mass materials are usually composed of cement, gypsum, sand, iron powder and barite. It can be supplied to the 3D molding machine for use.

[0003] At present, the mixing work of similar rock mass materials is basically done by ordinary concrete mixers in the construction industry, but ordinary concrete mixers will generate a lot of floating dust during operation, which seriously affects the environment in the laboratory; the feeding and ...
