Since the second opening 201 is connected to the detection channel 310, the operator can debug or repair the detection component in the detection channel 310 at the second opening 201, which is conducive to the convenience of operation. The second shielding member 22 blocks the second opening 201, and the outlet channel 210 is a closed channel.

[0076] The detection component 300 includes a support frame 31, a radiation source 32, a detector 33 and a grating assembly. The interior of the support frame 31 defines a detection channel 310, and the radiation source 32, the detector 33 and the grating assembly are installed on the support frame 31. The radiation source 32 and the detector 33 are arranged relative to each other, and the radiation source 32 can be installed at the lower left corner of the support frame 31, and the detector 33 is installed at the upper right corner of the support frame 31. The grating assembly includes a plurality of gratings, and the number of gratings is set according to actual needs. For example, the number of gratings is three, and the three gratings are respectively a first grating 34, a second grating 35 and an adjustable grating 36. The first grating 34 and the second grating 35 are fixedly installed on the support frame 31, and the adjustable grating 36 is movably installed on the inner wall surface of the support frame 31, and the position of the adjustable grating 36 can be adjusted.

[0077] The first grating 34 and the second grating 35 are arranged near the radiation source 32, and the first grating 34 and the second grating 35 are arranged at intervals. The first grating 34 includes a first horizontal arm 341 and a first vertical arm 342, and the second grating 35 includes a second horizontal arm 351 and a second vertical arm 352.

[0079] The radiation source 32 includes an X-ray machine, and the emitting end of the radiation source 32 is arranged at an angle. The radiation source 32 emits a beam of rays, which passes through the first horizontal arm 341, the second horizontal arm 351, and the movable horizontal arm 361 in sequence and is received by the horizontal arm detector, and the beam of rays passes through the first vertical arm 342, the second vertical arm 352, and the movable vertical arm 362 in sequence and is received by the vertical arm detector.

[0080] When installing the grating assembly, Figure 6 As shown, the first grating 34 and the second grating 35 are first installed on the fixing frame 315, and the alignment and adjustment of the first grating 34 and the second grating 35 are completed in the laboratory, and then the fixing frame 315 is installed on the supporting frame 31. Then, the adjustable grating 36 is installed on the inner wall surface of the supporting frame 31, the movable horizontal arm 361 is installed on the top wall surface of the supporting frame 31, and the movable vertical arm 362 is installed on the side wall surface of the supporting frame 31. The installation positions of the first grating 34, the second grating 35 and the adjustable grating 36 on the supporting frame 31 have an important influence on the quality of the scanned image.

[0081] The first grating 34 and the second grating 35 are relatively small in size, and the first horizontal arm 341, the first vertical arm 342, the second horizontal arm 351 and the second vertical arm 352 can be fixed to the fixing frame 315 by screwing. The adjustable grating 36 is relatively large in size.

[0082] Due to the limitation of manufacturing process, the size of the grating cannot be made very large, therefore, the movable horizontal arm 361 of the adjustable grating 36 is composed of multiple gratings, and the movable vertical arm 362 is composed of multiple gratings. The multiple gratings are sequentially installed on the top wall of the support frame 31, and the flatness of the top wall must be ensured; the multiple gratings are sequentially installed on the side wall of the support frame 31, and the flatness of the side wall must be ensured.

[0083] In the prior art, the support frame 31 is usually formed by welding a plurality of plate-like bodies. The welded support frame 31 will inevitably be deformed by welding, thereby affecting the accuracy of the installation position of each group of gratings.

[0084] In the embodiment of the present invention, the support frame 31 is an integrally formed part, and the support frame 31 can be integrally formed by 3D printing, or integrally formed by a casting process. For example, a blank of the support frame 31 is first prepared by a casting process, and then the blank is machined to ensure that each mounting surface and mounting hole meet the installation requirements, thereby preparing a support frame 31 that meets the installation requirements.

[0085] The raw material of the support frame 31 can be gray cast iron, which has good fluidity, is easy to cast, and has high processing accuracy. The support frame 31 has good rigidity and is not easy to deform, so that the relative position between each group of gratings is not easy to change, so that the positioning accuracy of the grating assembly is high. In addition, the casting has good shock absorption performance, which effectively avoids the influence of vibration on the installation position of the grating assembly.

[0086] The support frame 31 is integrally formed, has good rigidity and is not easily deformed, and can ensure the flatness of the mounting surface and the position accuracy of the mounting holes, thereby facilitating the position accuracy of each set of gratings.

[0087] In an embodiment of the present invention, the support frame 31 is integrally formed, has good rigidity and is not easy to deform, and the mounting surface of the support frame 31 has good flatness, which effectively ensures the accuracy of the mounting position of the radiation source 32, the detector 33 and the grating assembly, thereby facilitating ensuring the quality of the scanned image.

[0088] like Figures 3 to 5As shown, in an optional embodiment, the support frame 31 includes a first side support body 311, a second side support body 312, a top support body 313 and a bottom support body 314.

The top support body 313 is connected to the top of the first side support body 311 and the top of the second side support body 312. The bottom support body 314 is arranged opposite to the top support body 313 and is connected to the bottom of the first side support body 311 and the bottom of the second side support body 312.

[0089] The top support body 313 has a first mounting surface, the movable horizontal arm 361 is mounted on the first mounting surface, and the first side support body 311 has a second mounting surface, the movable vertical arm 362 is mounted on the second mounting surface.

[0090] Exemplarily, the first side support body 311 , the second side support body 312 , the top support body 313 , and the bottom support body 314 are prepared by a casting process.

[0091] The top support body 313 has a first mounting surface facing the bottom support body 314, and the movable cross arm 361 is mounted on the first mounting surface. The top support body 313 is prepared by a casting process, and the first mounting surface is machined on the top support body 313 by a machining process, and the first mounting surface has good flatness. The length and width of the first mounting surface match the length and width of the movable cross arm 361. The movable cross arm 361 is mounted on the first mounting surface, and the flatness of the first mounting surface can effectively ensure that the vertical spacing from each part of the movable cross arm 361 to the second cross arm 351 is the same.

[0092] The movable cross arm 361 includes a plurality of gratings, which are arranged in sequence along the length direction of the first mounting surface, and the interval between two adjacent gratings is required to be small enough.

[0093] Optionally, each grating is connected to the top support body 313 by screwing. For example, a through hole is provided on the grating, a threaded hole is drilled on the first mounting surface of the top support body 313, and screws are screwed into the through hole and the threaded hole to achieve the connection between the grating and the top support body 313.

[0094] like Figure 6 and Figure 7As shown, optionally, each grating 800 is fixed on an adjusting device 400, and the adjusting device 400 is connected to the top support body 313. The structure of the adjusting device 400 is described below. The adjusting device 400 can drive the grating 800 to move linearly along a first direction and a second direction. The first direction is consistent with the length direction of the grating 800, and the second direction is consistent with the thickness direction of the grating 800. The grating 800 moves along the first direction, and the spacing between two adjacent gratings 800 can be adjusted to ensure that the spacing between two adjacent gratings 800 is small enough. The grating 800 moves along the second direction, and the vertical spacing between the grating 800 and the second cross arm 351 can be adjusted.

[0095] The first side support body 311 has a second mounting surface facing the second side support body 312, and the movable vertical arm 362 is mounted on the second mounting surface. The first side support body 311 is prepared by a casting process, and the second mounting surface is machined on the first side support body 311 by a machining process, and the second mounting surface has good flatness. The length and width dimensions of the second mounting surface match the length and width dimensions of the movable vertical arm 362. The movable vertical arm 362 is mounted on the second mounting surface, and the flatness of the second mounting surface can effectively ensure that the lateral spacing from each part of the movable vertical arm 362 to the second vertical arm 352 is the same.

[0096] The movable vertical arm 362 includes a plurality of gratings, which are arranged in sequence along the length direction of the second mounting surface, and the interval between two adjacent gratings is required to be small enough.

[0097] Referring to the installation method of the multiple gratings of the movable horizontal arm 361, the multiple gratings in the movable vertical arm 362 can be connected to the first side support body 311 by screw connection, or can be connected to the first side support body 311 by the adjustment device 400. The grating 800 is connected to the first side support body 311 by the adjustment device 400. The grating 800 moves along the first direction, and the spacing between two adjacent gratings 800 can be adjusted to ensure that the spacing between two adjacent gratings 800 is small enough. The grating 800 moves along the second direction, and the lateral spacing between the grating 800 and the second vertical arm 352 can be adjusted.

[0098] Further, the detection device also includes a first support frame 600 and a second support frame 700, and the first support frame 600 and the second support frame 700 are arranged on the bottom support body 314 at intervals. The first support frame 600 is used to support the inlet channel component 100, and the second support frame 700 is used to support the outlet channel component 200. The first support frame 600 and the second support frame 700 can both be formed by welding profiles. For example, the first support frame 600 and the second support frame 700 are both formed by welding a plurality of square steel pipes.

[0099] The first support frame 600 and the second support frame 700 can be fixed to the bottom support body 314 by welding. The first support frame 600 and the second support frame 700 can also be connected to the bottom support body 314 by screwing.

[0100] The bottom support body 314 has a third mounting surface and a fourth mounting surface facing the top support body 313. The first support frame 600 is mounted on the third mounting surface, and the second support frame 700 is mounted on the fourth mounting surface. The bottom support body 314 is prepared by a casting process, and the third mounting surface and the fourth mounting surface are machined on the bottom support body 314 by a machining process. The third mounting surface and the fourth mounting surface have good flatness.

[0101] The first support frame 600 is installed on the third installation surface. The third installation surface has good flatness, which can effectively prevent the first support frame 600 from tilting, ensure that the docking positions of the entrance channel component 100 and the detection component 300 can be aligned, and further ensure the sealing of the docking point between the entrance channel component 100 and the detection component 300.
