X-ray parallel shielding device

Abstract

The invention discloses an X-ray parallel shielding device which comprises an X-ray shielding room. A conveyor used for conveying items to be detected is arranged in the X-ray shielding room, a discharge outlet and a feed inlet are formed in the two ends of the conveyor in the X-ray shielding room, an X-ray source is arranged below the conveyor, an X-ray detector is arranged above the conveyor and corresponds to the X-ray source, the conveyor is a parallel type conveyor, a plurality of adjustable ray refraction baffle sets are arranged above and below the conveyor in the X-ray shielding room in parallel, and each adjustable ray refraction baffle set is formed by two lead plates arranged by a certain included angle. The X-ray parallel shielding device is simple and effective in structure, low in designing and processing difficulty, low in structural cost, more stable than devices of conventional structures on the market, high in efficiency and capable of being generally applied to online automatic detection of factories.

Description

[0001] technical field [0002] The invention relates to the field of X-ray detection devices, in particular to an X-ray parallel shielding detection device. Background technique [0003] X-rays are characterized by a certain mass, energy and momentum when radiated and absorbed in the form of photons. It manifests itself in the exchange of energy when interacting with matter. Such as photoelectric effect; secondary electrons, etc., when high-speed moving electrons collide with objects, energy conversion occurs, and the movement of electrons is blocked and loses kinetic energy. A small part (about 1%) of the energy is converted into X-rays, and most (99%) %) energy is converted into heat energy to increase the temperature of the object, and the absorption of X-rays by substances refers to the transformation of X-ray energy into other forms of energy when passing through substances, and X-rays have energy loss. The absorption of X-rays by matter is mainly caused by electron ...

AI Technical Summary

Problems solved by technology

[0004] The X-ray shielding in the existing X-ray detection equipment is to shield the radiation through the closed lead room, climbing, turning, and the height difference between the luminous point of the radiation source and the inlet and outlet. This technology is used in online detection. The size of the workpiece has certain limitations, the cost is high, the movement mechanism is complex, the failure rate is high, and the efficiency is low
