Rock experiment standard test piece drying and heat shrink tube baking device and operation method thereof

Abstract

The invention discloses a rock experiment standard test piece drying and heat shrink tube baking device and an operation method thereof. The device is composed of a vacuum chamber, a drying chamber and a baking chamber. The drying chamber can be placed in the vacuum chamber and is used for drying a rock experiment standard test piece. The backing chamber can be placed in the vacuum chamber and is used for baking a heat shrink tube. Through the device, the experiment efficiency and experiment precision are greatly improved; the phenomenon of test piece and base dislocation caused by handholding and rotating an experimental device when a traditional heat gun is used for baking a rock experiment standard test piece and a heat shrink tube is effectively avoided; and the problem that the traditional heat gun scalds hands when used for baking the rock experiment standard test piece and the heat shrink tube is solved. Meanwhile, the drying chamber and the baking chamber can be rotated so as to achieve the even heating effect. Accordingly, the success rate of experiments is increased, and the accuracy of experiment results and data is improved.

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, rock standard 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 order to ...

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 rock standard specimen to remove the moisture in it
