Rock test standard specimen drying and heat shrinkable tube drying device and its operation method

Abstract

The invention discloses a rock experiment standard test piece drying and heat-shrink tube baking device and its operation method, which is composed of a vacuum chamber, a drying chamber and a baking chamber; the drying chamber can be placed in the vacuum chamber for baking Dry rock standard test piece; the baking chamber can be placed in a vacuum chamber for baking heat shrinkable tubing. The device greatly improves the experimental efficiency and accuracy, and effectively improves the phenomenon of the specimen and the base caused by hand-holding and rotating the experimental device when the standard heat-shrinkable tube of the rock experiment is baked by the traditional heat gun, and solves the problem of traditional heat gun drying. The problem of scalding hands when baking heat-shrinkable tubes of standard specimens for rock experiments. At the same time, the drying chamber and baking chamber can be rotated to achieve uniform heating effect, thereby improving the success rate of the experiment and the accuracy of the experimental results and data.

Description

technical field [0001] The invention belongs to rock experiment equipment. Background technique [0002] At present, the drying of standard specimens in rock mechanics experiments mostly uses special vacuum drying ovens, which cannot be dried conveniently and quickly on the test bench, and the cost of vacuum drying ovens is relatively high. [0003] In the test preparation stage, in order to study the strength characteristics and fluid-solid coupling characteristics of rocks, the standard rock test specimens are usually used for indoor triaxial or seepage experiments. The standard test piece is wrapped with a heat-shrinkable tube. The heat-shrinkable tube has the characteristic of shrinking when heated. The heat-shrinkable tube can be baked by a heat gun to make the heat-shrinkable tube tightly wrap the standard test piece, so as to prevent leakage of hydraulic oil. However, when using the traditional heat gun to bake the heat-shrinkable tube of the standard test piece, in ...

AI Technical Summary

Problems solved by technology

However, when using the traditional heat gun to bake the heat-shrinkable tube of the standard test piece, in order to meet the requirement of it being close to the test piece, it is necessary to hold it by hand or manually rotate the experimental device, which will easily cause the standard test piece and the base to be misaligned; in addition, the traditional The heat gun has only one air outlet. When baking the heat-shrinkable tube, the baking is only partially heated. After the block is baked, it is easy to cause the heat-shrinkable tube to be heated unevenly, which will affect the wrapping effect, thereby affecting the accuracy and results of the experiment. It is necessary to vacuum-dry the standard specimen of the rock experiment to remove the moisture in it
