The charge analysis device is connected to the user terminal, and the user terminal is used to judge whether the ion spectrum intensity is less than the preset Set value, if it is less than the preset value, t...

Embodiment 2

[0037] Such as figure 1 As shown, according to an embodiment of the present invention, a high-speed heavy ion belt flaw detection method is disclosed, comprising the following steps:

[0038] The low-energy ions are accelerated step by step to obtain high-speed heavy ions;

[0039] Measure the spectrum of the excited ion reflection after the high-speed heavy ions at different distances from the belt hit the belt coal;

[0040] It is judged whether the belt is damaged according to the spectral result, and if the spectral result is less than the preset value, the belt is damaged.

[0041] The spectra of excited ion reflections after the high-speed heavy ions hit the belt coal include:

[0042] The accelerated high-speed heavy ions hit the belt medium. When the high-speed heavy ions penetrate the medium film, the electrons in the belt medium produce strong Coulomb interaction, and a large number of electrons will be stripped off. After the high-speed heavy ions pass through the...

If not, the belt is damaged.

Description

technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a high-speed heavy ion belt flaw detection system and method. Background technique [0002] In coal mining, conveyor belts have been used for coal transportation. During the transportation process, there will be sharp coal and metal equipment that will damage the belt medium, which will bring huge harm and loss to the project or production. [0003] At present, the commonly used flaw detection devices for conveyor belts of belt conveyors mainly include X-ray transmission flaw detection devices and infrared flaw detection devices based on the principle of infrared flaw detection. [0004] However, the X-ray film and other equipment consumed by the X-ray transmission flaw detection device is expensive and the inspection speed is slow. It is only suitable for detecting volumetric defects such as pores, slag inclusions, shrinkage cavities, and porosity. It can be qualitative b...
