Description
Technical field
The present invention relates to X-ray check device field, survey device particularly to the parallel shielding of a kind of X-ray.
Background technology
Certain quality, energy and the momentum that X-ray feature has when showing as with form of photons radiation and absorb.The form of expression is positive energy exchange when with matter interaction.Such as photoelectric effect；Secondary electron etc., when the electronics of high-speed motion and object collision, there is energy conversion, the retard motion of electronics loses kinetic energy, wherein sub-fraction (about 1%) energy conversion is X-ray, and the overwhelming majority (about 99%) energy conversion becomes heat energy to make object temperature raise, material refers to X-ray energy and is changed into the energy of other form when by material the absorption of X-ray, and X-ray there occurs energy loss.X-ray is absorbed and is mainly caused by the electron transition of atomic interior by material.Photoelectric effect and the auger effect of X-ray is there is during this.
X-ray shielding in existing X-ray detection equipment is by closed lead room, climbing, turning and radiographic source luminous point shield ray with the mode of feed inlet and outlet difference in height, this technology has certain limitation to workpiece size size in using on on-line checking, cost is high, motion is complicated, fault rate is high, and efficiency is low.
Summary of the invention
In order to overcome drawbacks described above, the invention provides a kind of simple in construction, low cost, failure rate is low detection workpiece does not has the parallel screening arrangement of circumscribed X-ray.
The present invention is to solve that its technical problem be the technical scheme is that a kind of parallel screening arrangement of X-ray, including X-ray shield room, the conveyer of conveying article to be detected it is provided with in described X-ray shield room, be positioned at conveyer in X-ray shield room is respectively arranged at two ends with discharging opening and charging aperture, the lower section of conveyer is provided with x-ray source, corresponding conveyer be arranged over X-ray detector, described conveyer is run-in index conveyer, it is positioned in described X-ray shield room that the upper and lower of conveyer is parallel is provided with some groups of adjustable ray diffraction baffle plates, described often organize adjustable ray diffraction baffle plate and be made up of the stereotype of two pieces of settings in a certain angle.
As a further improvement on the present invention, adjustable adjustable import and export sized by described discharging opening and charging aperture.
As a further improvement on the present invention, described X-ray shield room is that lead is made.Described adjustable ray diffraction baffle plate height in X-ray shield room is adjustable, and the angle between two blocks of stereotypes of described adjustable ray diffraction baffle plate is also adjustable.
The invention has the beneficial effects as follows: the present invention uses run-in index radiation shield technology, run-in index conveyer detection workpiece, this structure X-ray shielding difficulty is big, the present invention mainly shields X-ray according to X-ray characteristic, X-ray is relative to regular motion with form of photons, the present invention is to be changed the movement locus of photon by adjustable ray baffle plate, photon energy energy when secondary excitation is made constantly to weaken, until there is no radiation leakage, air own also can make photon energy conversion thermal energy, this simple in construction is effective, Design and Machining difficulty is low, infrastructure cost is low, compared with routine structure on the market more stable, efficiency is high, routine applies to factory's online automatic detection.
