Description

Technical Field

[0001] The invention mainly relates to the field of food and pharmaceutical packaging, and in particular to a radiation protection delivery system. Background Art

[0002] Most common X-ray radiation protection transmission belts use a surrounding lead shielding tunnel plus lead curtains at both ends of the entrance and exit to provide radiation protection. (Such as common security inspection equipment in airports, subways, etc.) Because lead plates or lead curtains can absorb and shield radiation, and the radiation intensity decays inversely with the square of the distance, the X-rays bounce and absorb and decay repeatedly inside the tunnel, and are shielded by the lead curtains. At the exit, the X-ray radiation intensity has been greatly weakened, meeting national standards.

[0003] In the prior art, the movement trajectory of the inspected object on the transmission network is a straight line. In order to ensure that the radiation intensity at the inlet and outlet of the transmission network meets the requirements of relevant national standards, a radiation shielding protection tunnel with a sufficient safety length must be used. This significantly increases the equipment layout space and increases the radiation protection cost, which is not conducive to convenient use by customers. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a radiation protection delivery system which has a simple and compact structure, optimizes space arrangement, saves protection costs, and can prevent radiation leakage.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A radiation protection transport system comprises a first radiation shielding protection tunnel, a detection conveying track is provided in the first radiation shielding protection tunnel, radiation foreign body detection devices are arranged on both sides of the detection conveying track, the outlet of the first radiation shielding protection tunnel is connected to a second radiation shielding protection tunnel, the second radiation shielding protection tunnel is provided with a curved conveying track connected to the detection conveying track, and the second radiation shielding protection tunnel is provided with a plurality of radiation shielding protection baffles extending to corresponding recessed positions of the curved conveying track.

[0007] As a further improvement of the above technical solution:

[0008] The second radiation shielding protection tunnel includes two radiation shielding protection side panels, which are arranged at intervals and have radiation shielding protection top plates and radiation shielding protection bottom plates on their top and bottom portions. A channel connected to the exit of the first radiation shielding protection tunnel is formed between each protection plate. The curved conveying track is arranged in the channel, and each radiation shielding protection baffle is connected to the radiation shielding protection top plate and the radiation shielding protection side panel on the corresponding side.

[0009] Each of the radiation shielding protection baffles is perpendicular to the radiation shielding protection top plate and the radiation shielding protection side plates.

[0010] Each of the radiation shielding protection baffles coincides with the center line of each corresponding inner recess of the curved conveying track.

[0011] The second radiation shielding protection tunnel also includes a radiation shielding protection middle plate, and the radiation shielding protection middle plate is located below the curved conveying track.

[0012] The radiation shielding protection middle plate is perpendicular to the radiation shielding protection top plate and the radiation shielding protection side plates.

[0013] The curved conveying track comprises a curved conveying belt, and curved bottle protection fences are arranged on both sides of the curved conveying belt.

[0014] The detection conveying track comprises a detection conveying belt, and detection bottle protection fences are arranged on both sides of the detection conveying belt.

[0015] The radiation foreign body detection device comprises a radiation emitter and a radiation receiving detector, and the radiation emitter and the radiation receiving detector are respectively arranged on two sides of the detection conveying track.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] When the radiation protection conveying system of the present invention is used, the inspected product enters the first radiation shielding protection tunnel from the feeding end of the inspection conveying track, and the radiation foreign body detection device performs foreign body detection on the conveyed inspected product through X-rays. During the detection, the first radiation shielding protection tunnel is a complete radiation radiation shielding protection body, which can absorb most of the radiation. Only at the import and export positions of the inspected product, radiation enters the second radiation shielding protection tunnel. After the detection is completed, the inspected product enters the curved conveying track from the discharging end of the inspection conveying track. At this time, the second radiation shielding protection tunnel and each radiation shielding protection baffle absorb and shield the radiation, and finally the inspected product is sent out from the outlet of the curved conveying track. Compared with the traditional structure, the curved conveyor track changes the movement trajectory of the inspected product into a curved movement form, and at the same time, radiation shielding protection baffles are added to shield, block and absorb radiation. On the basis of ensuring radiation protection, the length of the second radiation shielding protection tunnel is greatly shortened. The structure is simple and compact, the space layout is optimized, and the protection cost is saved. The radiation shielding protection baffle divides the complete internal cavity of the second radiation shielding protection tunnel into multiple cross-shielded cavities, and at the same time reduces the size of the entrance and exit openings of the inspected product through the second radiation shielding protection tunnel, which greatly increases the probability of radiation being shielded, blocked and absorbed, and effectively prevents the possibility of radiation leakage.

[0023] like Figure 1 and Figure 2As shown, an embodiment of the radiation protection conveying system of the present invention includes a first radiation shielding protection tunnel 1, a detection conveying track 2 is provided in the first radiation shielding protection tunnel 1, radiation foreign matter detection devices 3 are arranged on both sides of the detection conveying track 2, the outlet of the first radiation shielding protection tunnel 1 is connected to the second radiation shielding protection tunnel 4, the second radiation shielding protection tunnel 4 is provided with a curved conveying track 5 connected to the detection conveying track 2, and the second radiation shielding protection tunnel 4 is provided with a plurality of radiation shielding protection baffles 6 extending to the corresponding recessed parts of the curved conveying track 5. When in use, the inspected product enters the first radiation shielding protection tunnel 1 from the feeding end of the inspection conveyor track 2, and the radiation foreign body detection device 3 performs foreign body detection on the conveyed inspected product through X-rays. During the detection, the first radiation shielding protection tunnel 1 is a complete radiation radiation shielding protection body, which can absorb most of the radiation. Only at the import and export positions of the inspected product, radiation enters the second radiation shielding protection tunnel 4. After the detection is completed, the inspected product enters the curved conveyor track 5 from the discharging end of the inspection conveyor track 2. At this time, the second radiation shielding protection tunnel 4 and each radiation shielding protection baffle 6 absorbs and shields the radiation, and finally the inspected product is sent out from the exit of the curved conveyor track 5. Compared with the traditional structure, the curved conveying track 5 changes the movement trajectory of the inspected product into a curved movement form, and at the same time, radiation shielding protection baffles 6 are added to shield, block and absorb the radiation. On the basis of ensuring radiation protection, the length of the second radiation shielding protection tunnel 4 is greatly shortened. The structure is simple and compact, the space layout is optimized, and the protection cost is saved; the radiation shielding protection baffles 6 divide the complete internal cavity of the second radiation shielding protection tunnel 4 into a plurality of cross-shielded cavities, and at the same time reduce the size of the entrance and exit openings of the inspected product through the second radiation shielding protection tunnel 4, which greatly increases the probability of radiation being shielded, blocked and absorbed, and effectively prevents the possibility of radiation leakage.

[0025] In this embodiment, each radiation shielding protection baffle 6 is perpendicular to the radiation shielding protection top plate 42 and the radiation shielding protection side plate 41.

[0027] In this embodiment, the second radiation shielding protection tunnel 4 further includes a radiation shielding protection middle plate 44, which is located below the curved conveying track 5. In this structure, the radiation shielding protection middle plate 44 is used to shield, block and absorb the gap below the curved conveying track 5 to prevent radiation from leaking from the gap below.

[0028] In this embodiment, the radiation shielding protection middle plate 44 is perpendicular to the radiation shielding protection top plate 42 and the radiation shielding protection side plate 41. This arrangement makes the radiation shielding protection middle plate 44 and the passage of the second radiation shielding protection tunnel 4 perpendicular to each other, ensuring the optimal shielding, blocking and absorbing effect of the radiation shielding protection middle plate 44.

[0029] In this embodiment, the curved conveying track 5 includes a curved conveying belt 51, and curved bottle protection fences 52 are arranged on both sides of the curved conveying belt 51. In this structure, the bottle body moves along the curved conveying belt 51 in a curved manner, and the curved bottle protection fences 52 form a bottle blocking and protecting effect on both sides of the curved conveying belt 51.
