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

Abstract

The invention discloses a mixer applicable to the 3D (three-dimensional) formation of large complex geological models, which comprises a mixing assembly, a feed assembly, a water supply assembly, an analogue material storage and weighing assembly, an additive storage and weighing assembly, a dust collection assembly, a filter assembly, and a discharge assembly; the feed assembly supplies an analogue material into the mixing assembly via the analogue material storage and weighing assembly, the water supply assembly is used for supplying clean water into the mixing assembly, the additive storageand weighing assembly is used for supplying additives into the mixing assembly, the dust collection assembly is used for removing floating dust produced in the preparation of the analogue material, the filter assembly is used for removing particles with grain sizes exceeding the standard in the analogue material, and the discharge assembly is used for supplying the mixed analogue material into aprinting head of a 3D forming machine. Since the mixer adopts an overall sealing design and has a dust-removing function, floating dust is prevented from being produced in the process of mixing; feeding and mixing are fully automatic; and in the process of mixing the analogue material, the mixer has a filtering function, so that particles with grain sizes exceeding the standard can be removed fromthe analogue material to prevent the printing head from being blocked.

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 ...
