An auxiliary device of an industrial ct scanning machine

Abstract

The invention discloses an auxiliary device of an industrial CT scanning machine, which is composed of a low-temperature refrigeration device, a loading device and a heat preservation device. Both the low-temperature refrigeration device and the loading device are placed inside the heat preservation device. During the test, the test sample was placed on the CT scanning table. The shell of the thermal insulation device is a metal shell, and the interior is filled with thermal insulation materials; it is ensured that the surface temperature of the sample can be kept within the set temperature range during the test. There is a double-glazed window on each side of the thermal insulation device, and an electronic heater is installed inside the glass window to prevent condensation and defrosting and ensure the test results of the industrial CT scanner. The invention can realize real-time scanning of rocks in a low-temperature pressurized state to ensure the accuracy of the test. The device has the characteristics of clear principle, simple structure, convenient use, stability and reliability.

Description

technical field [0001] The invention relates to industrial computed tomography imaging technology, in particular to an auxiliary device for an industrial CT machine, in particular to realize real-time scanning of rocks in a low-temperature pressurized state. Background technique [0002] CT scanning technology, or computerized tomography imaging technology, is a non-destructive testing technology that can clearly and accurately display the structural composition relationship and damage defects inside the detected object, and has many advantages such as obtaining high-resolution images and non-destructive testing. Based on the many advantages of CT scanning, CT technology has been applied to all directions in the rock field. However, due to the defects of industrial CT scanning machines, the rocks can only be pretreated in the research, and then the samples are put into the CT machine for scanning. However, it is difficult for existing CT scanners to perform real-time scanni...

Problems solved by technology

However, for samples under low temperature and pressure, it is difficult for existing CT scanners to scan in real time

[0003] At present, the main difficulties in realizing real-time scanning of CT scanner samples under low temperature and loading conditions are as follows: 1. Traditional low temperature conditions are mostly cooled by constant temperature water bath and liquid nitrogen spray cooling. This cooling method is easy to generate ice on the surface of the device, affecting the industry. CT scan image quality

2. The sample needs to be continuously rotated 360 degrees for scanning, therefore, the loading device needs to rotate synchronously with the CT rotary table for scanning

Currently, real-time scanning of rocks under low-temperature loading conditions is still blank
