The invention relates to an experimental test piece pretreatment device and method, in particular to a coal rock lossless infiltration-drying circulation pretreatment device and method. The device comprises fifteen parts including a box body, a water inlet, a water tank, small holes, an atomization humidifier, a drying machine, a storage support, a high-precision electronic balance, a temperature and humidity detection assembly, an inclined bottom plate, a drainage tank, a water outlet, a box door, a handle and a control host. An atomization humidifier infiltration method is adopted, and the vibration frequency of an atomization humidifier is controlled, water is atomized into ultrafine particles which uniformly permeate into the coal rock test piece from the surface so that the integrity of the test piece is ensured; the coal rock test piece is dried by controlling the drying temperature and the drying time of the drying machine on the side face of the box body, and the pretreatment purpose of lossless infiltration-drying circulation is achieved. The device has the characteristics of simplicity in operation, high efficiency, reliable result and capability of pretreating the test piece according to experimental requirements.
Description
technical field [0001] The invention relates to a laboratory test piece pretreatment device and method, in particular to a coal rock non-destructive infiltration-drying cycle pretreatment device and method. Background technique [0002] At present, the coal industry is in a critical period of comprehensive deepening reform, transformation and development, and more and more coal mines have been or are facing closure or abandonment. Combining the opportunities and challenges of the development of the coal mining industry under the background of "carbon neutrality and carbon peaking", using the underground space of abandoned mines to store water, and connecting roadways or safety coal pillars with artificial dams to form reservoir dams has been more and more popular in the world. more and more widely used. On the one hand, this is because the water cracks in the coal mining process cause the water in the aquifer to seep into the goaf, threatening the ecological environment of ...
