Description

Technical Field

[0001] The utility model relates to the technical field of radiation sterilization, in particular to an electron beam sterilization radiation protection shielding device. Background Art

[0002] Electron beam sterilization is a modern sterilization technology that can effectively kill bacteria, fungi, viruses and other microorganisms. It can replace traditional heat sterilization technology and is an advanced and efficient sterilization method. It uses electron beam rays to decompose the cell walls, proteins, nucleic acids and cytoplasm of microorganisms, causing chemical changes in the material structure, and the microorganisms lose their ability to survive, thereby achieving the effect of killing microorganisms. The distance between the electron accelerator radiation source and the disinfected object of the current electron beam sterilization equipment is mostly fixed. When the disinfected object is sent into the electron beam sterilization equipment, the disinfected object cannot form a closed space with the electron accelerator radiation source.

[0003] For example, a Chinese utility model patent with announcement number CN209030068U discloses an electron beam sterilization radiation shielding device. The electron accelerator radiation source of this solution is located on the upper side of the container moving line. When the automatic production line starts to feed the sterilized objects into it, there is a certain distance between the sterilized objects and the electron accelerator radiation source, and it is impossible to form a closed space. This may cause the movable door on one side of the electron beam sterilization equipment to open when the sterilized objects enter the electron beam sterilization equipment from the assembly line, and the radiation and rays inside the irradiation equipment may leak. Based on this, an electron beam sterilization radiation shielding device is proposed. Summary of the invention

[0004] In order to solve the technical problem of radiation shielding in electron beam sterilization, the utility model provides an electron beam sterilization radiation shielding device.

[0006] As a further improvement of the above scheme, the skateboard driving mechanism includes a cylinder fixedly connected to one side of the track plate, an output end of the cylinder is fixedly connected to an O-type push ring, and one side of the track plate is provided with a push ring limiting mechanism for limiting the movement of the O-type push ring.

[0007] As a further improvement of the above-mentioned scheme, the push ring limiting mechanism includes No. 2 card grooves opened at both ends of the O-shaped push ring, and the inner sides of the two No. 2 card grooves are respectively slidably connected with limit plates fixedly connected to one side of the track plate, and the inner side of the O-shaped push ring is provided with a connecting plate driving mechanism that enables the lifting connecting plate to reciprocate vertically up and down.

[0009] As a further improvement of the above solution, the loading platform placement mechanism includes a sterilization placement plate fixedly connected to the upper end of the lifting connecting plate, and springs are respectively arranged between the lower sides of both ends of the sterilization placement plate and the slide plate.

[0010] Through the above technical solution, when the slide rod completes a cycle of operation in the special-shaped slide groove and transfers in an arc shape from the lower side to the upper side of the special-shaped slide groove, the spring is still in a compressed state. When the slide rod runs to the maximum point of the arc, that is, the horizontal radius, the spring still has an upward spring pull on the slide rod. When the cylinder starts again to push the O-shaped push ring, the slide rod can smoothly switch into the upper track groove of the special-shaped slide groove and enter the next cycle of operation.

[0011] As a further improvement of the above scheme, the irradiation sterilization mechanism includes a horizontal channel fixedly connected to the upper sides of the two track plates, the upper side of the horizontal channel is connected to an ascending channel, the upper side of the ascending channel is connected to an irradiation chamber, and the upper side of the irradiation chamber is fixedly connected to an electron accelerator.

[0012] As a further improvement of the above solution, the unloading platform mechanism includes an unloading platform fixedly connected to one end of the two track plates.

[0013] Through the above technical solution, a related unloading structure can be set on the unloading table to automatically transfer or manually transfer the sterilized materials.

The objects to be sterilized are placed on the sterilization placement plate and move along the upper slide groove of the special-shaped slide groove. After the sterilization is completed, the materials are unloaded at the unloading table, and then the sterilization placement plate returns along the lower slide groove part of the special-shaped slide groove. In this way, the objects on the assembly line are sterilized one by one periodically, which can improve the working efficiency of the electron beam sterilization equipment.

[0028] Please combine Figure 4 As shown, the push ring limiting mechanism includes No. 2 slots 19 opened at both ends of the O-type push ring 11, and the inner sides of the two No. 2 slots 19 are respectively slidably connected with limiting plates 14 fixedly connected to one side of the track plate 2, and the inner side of the O-type push ring 11 is provided with a connecting plate driving mechanism that enables the lifting connecting plate 1 to reciprocate vertically up and down.

[0029] Please combine Figure 2 As shown, the connecting plate driving mechanism includes a special-shaped slide groove 13 opened on the inner side of the two track plates 2. It is necessary to specially explain the technical characteristics of the slide groove direction of the special-shaped slide groove 13. Half of a standard arc slide groove with the same radius is arranged at both ends of the special-shaped slide groove 13. The horizontal slide groove connected to the lower side of the arc slide groove is used for return transfer, and a slide groove structure is arranged above the arc slide groove, which first rises and then descends, and then enters the arc slide groove track at one end. The inner sides of the two special-shaped slide grooves 13 are slidably connected to a slide rod 15 which is slidably connected to the inner side of the O-type push ring 11 and fixedly connected to the lower end of the lifting connecting plate 1.

[0030] Please combine Figure 1 As shown, the loading platform placement mechanism includes a sterilization placement plate 7 fixedly connected to the upper end of the lifting connecting plate 1. The sterilization placement plate 7 can be selected to a specific size according to the actual goods placed. It should be particularly noted that the size of the sterilization placement plate 7 and the size of the objects to be sterilized need to be determined in combination with the specifications of the ascending channel 18 to avoid interference with the inner wall of the ascending channel 18. Springs 8 are respectively arranged between the lower sides of the two ends of the sterilization placement plate 7 and the slide plate 9.

[0031] Please combine Figure 2 As shown, the irradiation sterilization mechanism includes a horizontal channel 3 fixedly connected to the upper sides of the two track plates 2, the upper side of the horizontal channel 3 is connected to an ascending channel 18, the upper side of the ascending channel 18 is connected to an irradiation chamber 17, and the upper side of the irradiation chamber 17 is fixedly connected to an electron accelerator 6.

[0034] The implementation principle of an electron beam sterilization radiation shielding device in the embodiment of the present application is as follows: place the goods to be sterilized on the sterilization placement plate 7, start the cylinder 12, and push the O-type push ring 11 to move to one side along the limit plate 14. At this time, the slide bar 15 is pushed by the O-type push ring 11 and makes a circular reciprocating motion along the inner side of the special-shaped slide groove 13. When the slide bar 15 is in the ascending stage of the special-shaped slide groove 13, the slide bar 15 pushes the lifting connecting plate 1 to slide upward along the slide plate 9, and the spring 8 is deformed and stretched, and at the same time pushes the slide plate 9 to slide to one side along the No. 1 card slot 10. When the lifting connecting plate 1 rises to the highest end, the sterilization placement plate 7 first passes through the ascending channel 18 and then enters the irradiation chamber 17. At this time, the electron accelerator 6 is started. The objects can be irradiated and sterilized; when the sterilization placement plate 7 moves to the end of the track plate 2, the sterilized objects can be transferred by manual unloading or mechanical unloading mechanism at the unloading platform 5, and the slide bar 15 at this time has a tendency to move downward under the action of its own gravity and the tension of the spring 8. The slide bar 15 can enter the horizontal track below the special-shaped slide groove 13 and move back. When it moves to the end of the slide groove below the special-shaped slide groove 13, the spring 8 has a tendency to compress and rebound. When the cylinder 12 pushes the O-type push ring 11 to coincide with the maximum critical point of the arc slide groove, the slide bar 15 is pushed by the spring 8 and the cylinder 12 at this time. The push of the change of direction, smoothly switches to the slide groove above the special-shaped slide groove 13 and enters the next cycle of movement.
