Description

A control system for controlling irradiation box to perform irradiation operation

Technical Field

The invention relates to an irradiation management and control system, in particular to a control system for controlling an irradiation box to perform irradiation operation.

Background Art

Radiation processing refers to the process of using gamma rays and electron beams generated by accelerators to irradiate the processed objects to improve their quality or performance. Radiation processing can obtain high-quality chemical materials, store and preserve food, disinfect medical equipment, treat environmental pollutants, etc. It can be used for radiation modification of polymer materials, food irradiation preservation, and radiation disinfection of sanitary medical supplies. Radiation processing technology has the following characteristics: ① The irradiation process is not affected by temperature and can be carried out at low temperature or room temperature, so the irradiated object can be gaseous, liquid or solid; ② Gamma rays or high-energy electron beams have strong penetrating power and can penetrate evenly into the interior of the object, so they can be processed in the packaged or encapsulated state; ③ Easy to control and suitable for continuous operation; ④ No other chemical reagents and catalysts need to be added to ensure product purity; ⑤ Fast reaction rate, forming an efficient production line.

At present, during irradiation processing, the packaged materials are placed in the irradiation box, and then the irradiation box enters the irradiation room on a circulating track for irradiation treatment. However, when the materials are placed in the irradiation box and taken out, they are generally handled by manpower. At this time, the irradiation box needs to have a special platform, which is inefficient and cannot fully meet the entry and exit management of the irradiation box. At the same time, the process of manually placing and taking out the packaged material box into the irradiation box on the platform increases the possibility of foreign debris being contained in the irradiation box, and increases the frequency of cleaning the irradiation box.

The loading device, fault irradiation track device, unloading device and switching device are all connected to the control server, and RFID readers are arranged at the loading device, fault irradiation track device, unloading device and switching device. An RFID tag is arranged on the outer surface of the irradiation box. The loading device, fault irradiation track device, unloading device and switching device read the RFID tag of the irradiation box through the RFID reader to determine the travel route or irradiation times of the irradiation box.

As shown in FIG1 , the loading device comprises a loading elevator 7 located below the irradiation box feeding conveyor belt 6 and a loading door opening unit located above the irradiation box feeding conveyor belt 6 .

The irradiation box feeding conveyor belt 6 conveys the irradiation box 8 to the loading elevator 7, and then defines the irradiation box front door 9 of the irradiation box 8 through the loading door opening unit. The loading door opening unit includes a horizontal piston 12 installed on an outer frame 11, and the horizontal piston 12 drives the lifting piston 14 forward or backward through the horizontal piston rod 13, and the lifting piston 14 drives the probe plate 16 to rise or fall through the lifting piston rod 15.

Slide rails are arranged on the left and right sides in front of the irradiation box 8 for placing the front door 9 of the irradiation box. A convex plate 10 is arranged at the front end of the front door 9 of the irradiation box. Through the action of the horizontal piston 12 and the lifting piston 14, the probe plate 16 is extended under the convex plate 10. When the loading elevator 7 drives the irradiation box 8 to descend, the position of the front door 9 of the irradiation box remains stationary, so that the front of the irradiation box 8 is exposed and the loading box 2 can be loaded.

As shown in FIG2 , the box conveyor belt 1 transports the box 2, and a corresponding number of boxes 2 are placed on the box conveyor belt 1 facing the irradiation box 8, and then the box 2 is pushed into the irradiation box 8 by the push plate 5. The push plate 5 is connected to the material piston rod 4, and the material piston 3 controls the forward or backward movement of the push plate 5 by the material piston rod 4. The operation of the material piston 3 is processed by the control server.

As shown in FIG3 , the fault irradiation track device is provided with multiple groups, and the multiple groups of fault irradiation tracks are connected in sequence and arranged in a serpentine shape that bypasses the irradiation source 17. A radiation-blocking wall 18 is provided on the periphery of the irradiation source 17, and a second layer of surrounding wall is provided outside the wall 18 to prevent radiation exposure. Radiation-proof buildings are also provided above and below the entire irradiation room.

As shown in FIG4 , the fault irradiation track device is divided into multiple layers arranged in sequence from top to bottom, each layer is provided with a staggered conveyor belt 20, and a staggered elevator 19 is provided at the end of the transmission direction of the staggered conveyor belt 20, which is used to lift and transport the irradiation box to the staggered conveyor belt of the upper layer, or lower and transport it to the staggered conveyor belt of the next layer.

In this way, the irradiation box 8 can form a serpentine forward route in the vertical direction, and the staggered conveyor belt at the highest or lowest layer at the end of the movement can directly transmit to the highest or lowest layer of the next set of fault irradiation tracks, and then form a serpentine forward route in the vertical direction of the next set of fault irradiation tracks.

As shown in Figure 5, the unloading device includes a unloading pushing unit and a side plate lifting unit. When the irradiation box passes through the output track of the unloading device, that is, the irradiation box discharge conveyor belt 21 reaches the unloading point, the unloading pushing unit is located on the left side of the irradiation box discharge conveyor belt 21, and the side plate lifting unit is located above the irradiation box discharge conveyor belt 21.

The unloading pushing unit includes a pushing piston 23 , a pushing piston rod 24 , and a pushing plate 25 . The pushing piston 23 drives the pushing plate 25 forward or backward through the pushing piston rod 24 .

The side plate lifting unit includes a stretching device 29, a lifting piston 30, and a lifting piston rod 31. The lifting piston 30 is fixed to the outer frame 11. The lifting piston 30 drives the stretching device 29 to move up and down through the lifting piston rod 31. As shown in Figure 6, the stretching device 29 includes a motor 32, a rotating wheel 33, and an extension rod 34. The motor 32 is connected to the rotating wheel 33 to drive the rotating wheel 33 to rotate. The extension rod 34 is divided into two and is arranged on both sides of the rotating wheel 33. It is connected to the rotating wheel 33 through a gear. When the rotating wheel 33 rotates, it drives the two extension rods to extend to the bottom of the connecting plate 28 or retract to the middle of the two connecting plates 28.

When in use, the extending device 29 descends to the upper surface of the irradiation box 8, and then the extension rod is extended; the extending device 29 is lifted, driving the left box plate 26 and the right box plate 27 on the left and right sides of the irradiation box 8 to rise. Slide rails are also set on the frame on the left and right sides of the irradiation box 8 to accommodate the left box plate 26 and the right box plate 27. The top of the left box plate 26 and the right box plate 27 are fixedly connected by a connecting plate 28. The height of the connecting plate 28 is higher than the upper surface of the irradiation box 8, so that the extension rod 34 can reach below the connecting plate 28 when extended.

After the left box plate 26 and the right box plate 27 are lifted into place, the pushing piston 23 works, so that the pushing plate 25 extends from the left side into the irradiation box 8, pushing the material box 2 onto the material box conveyor belt 22, and then transporting it to the warehouse or loading it onto a truck.
