Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not to be construed as limiting the utility model. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
Fig. 1 is an overall schematic view of a static CT detection apparatus according to an embodiment of the present invention. Fig. 2 is a sectional view of a static CT inspection apparatus according to an embodiment of the present invention, taken in a direction perpendicular to a conveying direction of the moving passage shown in fig. 1. The detailed description is made with reference to fig. 1 and 2.
The static CT examination apparatus comprises a shield 1, a frame 2, a radiation source 3 and a detector 10. The shield 1 surrounds a detection passage G through which an object to be detected can pass. The shield 1 is supported by the frame 2, but the shield 1 may be placed directly on the floor without providing the frame 2. The radiation source 3 emits radiation for detecting an object to be detected when the object passes through the detection passage G. The detector 10 acquires the radiation emitted by the radiation source 3 that passes through the detection channel G. An opening 4 is formed in the shield 1, and the opening 4 extends from the entrance of the detection channel G to the exit of the detection channel G.
In this embodiment, the meat material 9 is used as an example of the object to be detected.
The shield 1 has an opening 4 at the top. The meat material 9 is typically hoisted on a pipeline for transport, inspection, and processing. As shown in fig. 1, the means for conveying the meat mass 9 includes a flow line 6, a lifting means 8 and a driving means not shown. The pipeline 1 is arranged above an opening 4 of the static CT detection device. The lifting member 8 which drives the meat material 9 through the detection channel G extends to the detection channel G through the opening portion 4.
When the driving part not shown works, the hoisting part 8 drives the meat material 9 to move, and when the meat material passes through the upper part of the static CT detection device, the hoisting part 8 extends into the detection channel G through the opening part 4 and drives the meat material 9 to move from the inlet of the detection channel G to the outlet of the detection channel G. The meat material 9 does not contact the shield 1 when being carried through the detection passage G by the lifting member 8, and the meat material 9 is not supported or carried by the shield 1. When the meat mass 9 passes a position corresponding to the radiation source 3, the radiation source 3 emits an exit ray, detecting the meat mass 9. Then, the detector facing the radiation source 3 captures the radiation incident inside and detects the radiation.
By providing the opening 4 in the shield 1, the static CT inspection apparatus can be highly integrated with the line, and an additional transport device is not required. In this embodiment, the meat material 9 is directly carried into the detection device through the flow line without moving the meat material onto the conveyor belt, so that the time required for detecting the meat material 9 can be saved, and the detection and the processing can be conveniently completed on the flow line. In addition, when meat is detected, detection equipment does not need to be inserted into the meat, non-contact detection of the meat is achieved, and the risk of cross contamination is avoided. In addition, in the present embodiment, since the meat material 9 does not contact the shield 1, it is possible to reduce contamination of the static detection CT apparatus, keep the inside clean, and reduce the number of times of cleaning. In addition, in the embodiment, the sorting can be performed in a production line instead of a manual work.
Optionally, as an embodiment, the static CT detecting apparatus further includes a shield cover 7, which is driven by a driving member, not shown, to move along the flow line 6 together with the hoisting member 9, and the shield cover 7 covers the opening 4 of the static CT detecting apparatus when the hoisting member 9 passes through the opening 4. Radiation from the detection channel G can thus be effectively prevented.
Optionally, as an embodiment, the static CT detection apparatus further has a standing shielding wall 5, and fig. 3 is a cross-sectional view of a labyrinth cover of the static CT detection apparatus. The rising shield wall 5 is provided rising in a direction orthogonal to the shield body 1 on both sides of the opening 4, and the shield cover 7 covers the rising shield wall 5 when passing through the opening 4. Thus, by forming the shield structure in which the rising shield wall 5 and the shield cover 7 form a labyrinth shape, radiation in the detection passage G can be effectively prevented from being radiated to the outside.
The radiation source and the detector according to the above embodiments will be described in detail below. Fig. 4 is a schematic configuration diagram of a radiation source and a detector of a static CT inspection apparatus according to an embodiment of the present invention.
In this embodiment, the radiation source includes a plurality of distributed radiation sources, and the distributed radiation sources are disposed outside the inspection passage and around the portion other than the opening portion on a plane orthogonal to the direction in which the object to be inspected is conveyed along the inspection passage. The distributed radiation sources may be arranged continuously or intermittently. As shown in fig. 4, several distributed radiation sources are connected end to form a radiation source. That is, the radiation source 3 includes a plurality of distributed radiation sources provided in the same plane orthogonal to the direction in which the object to be detected is conveyed along the detection path and in a portion other than the opening. Of course, the plurality of distributed radiation sources may be arranged in a plurality of different planes orthogonal to the direction of conveyance of the object to be inspected along the inspection passage, for example, the radiation sources arranged in the plurality of planes may be arranged end to end when projected onto the same one of the planes. Figure 4 shows a 6-group source arrangement. Each distributed ray source comprises a plurality of ray point sources. Each ray point source emits fan-shaped X-rays in a controllable state, and the X-rays can cover a part of the scanning channel. The scanning angle of the distributed ray source to any point in the channel meets the CT reconstruction imaging requirement, for example, exceeds 180 degrees. The distributed ray sources are arranged according to the target coverage length required by CT reconstruction imaging and the size of a single ray source.
Fig. 5 is a schematic configuration diagram of a radiation source and a detector of a static CT inspection apparatus according to another embodiment of the present invention. In the present embodiment, a polygonal distributed ray source 30 is employed.
As shown in fig. 4 and 5, the detector 10 is provided outside the detection passage and around the portion other than the opening portion corresponding to the radiation source on the plane orthogonal to the direction in which the object to be detected is conveyed along the detection passage. The detection source may be provided continuously or intermittently. The detector 10 acquires radiation emitted from the source from opposing directions through the detection channel. The detector ring formed by the detector around the shield and the ray source ring formed by the ray source around the shield are staggered with a certain distance in the direction of the detection channel, so that the detector cannot shield rays emitted by the ray source at the rear part of the detector.
In the above-described embodiment, the rectangular detection channel is exemplified, but not limited thereto. The shape of the detection channel can be made into any shape such as an ellipse, other polygons and the like according to the requirements of the detected object. The height and width dimensions of the detection channel can be designed into different dimensions according to requirements. When the detection channels are different in size, the number of the detectors and the ray sources can be increased or decreased according to the size, so that devices with different sizes can share the same ray source and detector components, and the cost is reduced.
In the above-described embodiment, the description has been given taking the example in which the position of the opening is located at the top of the shield, but the present invention is not limited to this. Depending on the object to be detected and the specific configuration of the line, the opening may be provided at a side surface, a bottom surface, or the like of the shield. In addition, the size and configuration of the openings depends on the particular configuration of the pipeline.
In the above embodiments, the target point of the distributed ray source may be linear, curved or polygonal. The radiation sources can be arranged in a multi-segment broken line shape or in a curve shape according to the shape of the detection channel. The target points of the ray sources can be continuously and uniformly arranged or discontinuously and non-uniformly arranged. In addition, the distributed ray source can also be formed by a broken line type distributed ray source.
In the above embodiments, the radiation source is exemplified by a distributed radiation source, but is not limited thereto. The ray source can also be a combination of single-point ray sources. In addition, the single-point radiation source can be arranged continuously or discontinuously.
In the above-described embodiment, the detectors may also be arranged in a multi-segmented zigzag shape or in a curved shape according to the shape of the detection channel. In addition, the detectors may be arranged in a continuous uniform manner or in an intermittent non-uniform manner. When the detector is not completely arranged to cause the loss of partial scanning data, a data compensation mode can be adopted to compensate, so that a complete CT reconstruction image is formed.
In the above-described embodiments, the detection of the meat material is described as an example. However, the present invention is not limited to meat materials, and any object may be used as long as it is processed in an in-line and requires CT detection.
Although the embodiments and specific examples of the present invention have been described above with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
