Specific embodiment
The technical solution adopted in the present invention is further described below in conjunction with schematic diagram.
Such as Fig. 1, a kind of intelligence X-ray security detection equipment collimation, radiographic source and detection acquisition system comprising: X-ray hair
Source 10 is penetrated, for the X-ray emission source for issuing X-ray, the output end of X-ray emission source arranges once collimation unit 20, primary to collimate
The X-ray that unit 20 issues X-ray emission source is once collimated, and the X-ray dissipated at this time is carried out for the first time by a collimation unit
Collimation, then abutting joint has secondary collimation unit 30 to a collimation unit output end, and secondary collimation unit is to by primary collimation
X-ray carry out secondary collimation, then correspondence is equipped with curved detector array box 40 to secondary collimation unit X-ray outbound course, the arc
Shape detector array box 40 can refer to our company application patent (patent No.: 201721877195.3, a kind of patent name: arc
Shape detector array box).
Intelligence X-ray security detection equipment collimation, radiographic source and detection acquisition system provided by the invention can send out X-ray
The X-ray for penetrating source sending is collimated twice, and collimation preferably can correctly be directed at X-ray detection board twice, thus more preferably
Satisfaction will transmit through the X-ray of object to be detected and be conveyed to curved detector array box 40.
Referring to Fig. 1, a collimation unit 20, secondary collimation unit 30 have the collimating channel that communicates, and X-ray is from X-ray
After emission source issues, collimation of the width of X-ray by collimation unit twice, the width (left and right directions of Fig. 1) of the collimating channel
It is gradually increased from a collimation unit towards secondary collimation unit.By two-stage collimating structure, X-ray can preferably be collimated with
Article to be detected in X-ray detection equipment is detected.
In conjunction with Fig. 1,3 it is found that a collimation unit has the first upside-down trapezoid for being installed on X-ray emission source exit
Part is collimated, the lower width that the first upside-down trapezoid collimates part is less than upper width and the width from lower part towards top is gradually to become
Big, the first standard that width is gradually increased from arrival end towards outlet end width is provided in the first upside-down trapezoid collimation part
Straight channel, the width in the first collimating channel is gradual change, and (front-rear direction of Fig. 1 is the first collimating channel to the height in channel
Short transverse) be then identical.The secondary collimation unit has the inversion U for being installed on a collimation unit X-ray output end
The X-ray exit portal of type part, inverted u-shaped part is located on level board, the height (front and back of Fig. 1 of X-ray exit portal set by level board
Direction) it is smaller than the height of the first collimating channel, to preferably constrain the outgoing state of X-ray, the X-ray of the inverted u-shaped part
The height of exit portal can preferably complete collimating effect less than the height of the first collimating channel.
It should be noted that emission source and detecting object are distant, it is first if primary collimation is accomplished secondary collimation position
The big problem of collimation device difficulty of processing is pre-existed, furthermore, collimator height increase is bad to detection board, passes through the knot of this case
Structure then can solve above-mentioned technology drawback.
From figure 3, it can be seen that the initial segment of a collimation unit is provided with lead quality guarantee guard 50, the present invention is first one
Then secondary collimation and detection board install secondary collimation good energy, secondary collimation height is in 30mm, secondary collimating slit ratio
Once collimate it is small, in this way can be less to X-ray leakage.It is required that energy cannot reduce, it is the gap bridge set not collimated in the middle.
Intelligent X-ray security detection equipment of the invention collimates, in radiographic source and detection acquisition system, the inverted u-shaped
Part, which is provided with, is installed on the first collimation unit output end fixing screw hole for inverted u-shaped part, and the inverted u-shaped part passes through screw 60
It is removably installed in first collimation unit, the U-shaped inversion part is provided with the opening to match with the second collimating channel.
The X-ray that X-ray emission source issues passes sequentially through the first collimating channel, the second collimating channel, then (is placed in by examined object
Between second collimating channel output end and curved detector array box 40), last X-ray is received simultaneously by curved detector array box 40
Processing, X-ray use cambered design by curved detector array box 40, and possessed acquisition receiving body is around X-ray source arc-like rows
Column, acquisition receiving body can equably be received emitted x-ray energy, can preferably be carried out using received energy
Product testing more accurately carries out detection judgement to the contraband in inspected object.
In system provided by the invention, it can be more convenient with this principle the energy pair between emission source and detection board
To best, and it is convenient to energy, processing cost can also be reduced.
The above is only a preferred embodiment of the present invention, does not play the role of any restrictions to the present invention.Belonging to any
Those skilled in the art, in the range of not departing from technical solution of the present invention, to the invention discloses technical solution and
Technology contents make the variation such as any type of equivalent replacement or modification, belong to the content without departing from technical solution of the present invention, still
Within belonging to the scope of protection of the present invention.
