Description

Technical Field

[0001] This utility model relates to the technical field of enclosed environmental protection boxes for sample preparation machines, and in particular to an enclosed environmental protection box for sample preparation machines. Background Technology

[0002] In rock mechanics research and engineering practice, accurately measuring various parameters of rocks is crucial. Rock tests, such as splitting tensile tests and shear tests, provide critical data support for engineering design and geological hazard assessment. The precision of rock sample preparation directly determines the reliability and accuracy of these test results. The GB / T23561.11-2024 standard explicitly emphasizes the importance of preparing high-quality rock samples. As a key piece of equipment for rock sample preparation, the performance and usage of the sample preparation machine play a decisive role in the quality of sample preparation.

[0003] However, traditional sample preparation machines have serious problems during use. During operation, water is required as a coolant, which mixes with the stone powder produced during grinding to form a turbid slurry. This slurry splashes everywhere, not only polluting the experimental space and making the equipment and surrounding environment dirty and messy, but also significantly increasing the concentration of airborne particles. Prolonged exposure to such an environment, with researchers inhaling air containing stone powder particles, may cause respiratory and lung diseases, posing a significant threat to their health. Furthermore, the slurry splashing may also affect the normal operation of the sample preparation machine and reduce its lifespan. Therefore, we propose a closed, environmentally friendly sample preparation box to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a closed and environmentally friendly sample preparation box.
