Description

Technical Field

[0001] The utility model relates to the field of sterilization, in particular to a radiation sterilization device. Background Art

[0002] Irradiation sterilization is an effective method of killing microorganisms on most substances using ionizing radiation. This method is widely used in fields such as medicine, food processing, pharmaceuticals, and semiconductor manufacturing.

[0003] Over the past few decades, scientists have been investigating how to more effectively utilize ionizing radiation for sterilization. Early research focused on the use of ultraviolet (UV) and X-rays for sterilization. However, these methods have several limitations, including complex equipment, high costs, and safety concerns for both operators and the environment.

[0004] With the advancement of technology, people have begun exploring the use of gamma rays for sterilization. Gamma rays, with their strong penetrating power, high energy, and excellent bactericidal effect, are considered an ideal sterilization method. However, due to the high intensity of gamma rays, the radiation source must be properly arranged, and the device must have good barrier properties to prevent gamma ray damage to operators and the environment. However, existing assembly-line irradiation sterilization devices mostly use single-layer flexible doors, which have limited barrier properties and gamma rays can easily penetrate through gaps when the door is tilted upward.

[0015] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0016] Example 1

[0017] like Figures 1 to 3The irradiation sterilization device shown in the figure has a conveyor frame 2 fixed on the top of the support base 1, and a conveyor belt 3 driven by a motor 4 is installed in the conveyor frame 2. An irradiation box 5 is provided in the middle of the upper side of the conveyor frame 2, and the irradiation box 5 is located on the upper side of the conveyor belt 3. An irradiation component 503 for irradiating directly downward is provided in the irradiation box 5. A through door 501 is provided at the lower part of the front and rear walls of the irradiation box 5, and a flexible inner curtain 502 is provided at the through door 501. The inner curtain 502 closes the through door 501, and the inner curtain 502 is composed of several closely arranged barrier strips 512. An outer box 6 is also provided on the outer side of the front and rear walls of the irradiation box 5, and an outer door 601 is provided on the outer wall of the outer box 6. An outer curtain 602 is provided at the outer door 601, and the outer curtain 602 closes the outer door 601. The outer curtain 602 also has closely arranged barrier strips 512. The length of the outer box 6 is greater than the length of the sterilization box 7 entering the irradiation box 5.

[0018] When the sterilization box 7 enters the irradiation box 5 along the conveyor belt, it will first pass through the outer box 6. When the sterilization box 7 pushes open the barrier strip 512 on the outer curtain 602, the barrier strip 512 of the inner curtain 502 will completely close the through door 501. The barrier strip 512 is made of a material that can block radiation, which can prevent the radiation from being emitted outward from the irradiation box 5 or the outer box 6 when the irradiation lamp 523 is started.

[0019] The irradiation assembly 503 is composed of an irradiation lamp 523 and an outer cover 513. The outer cover 513 is a downwardly opened irradiation box. The irradiation lamp 523 is installed on the lower side of the outer cover 513 so that the rays emitted by the irradiation lamp 523 will not diverge to the surroundings.

[0020] The upper side of the outer cover 513 is connected and fixed to the lifting rod 504, and the rear section of the lifting rod 504 is fixed on the irradiation box 5. The irradiation assembly 503 can be raised and lowered, so that the height of the irradiation assembly 503 can be easily adjusted to adapt to the sterilization irradiation of different items.

[0021] Example 2

[0022] In this embodiment, in order to improve the efficiency of sterilization, holes 8 with the same spacing are opened in the middle of the conveyor belt 3, and the sterilization box 7 can be placed in the hole groove 8. A fixed plate 9 is set in the middle of the conveyor frame 2, and the fixed plate 9 is located between the upper and lower layers of the conveyor belt 3. An irradiation component 503 is installed in the middle of the fixed plate 9. The irradiation lamp 523 of the irradiation component 503 irradiates upward, and the two groups of irradiation components 503 are facing each other up and down; the upper and lower irradiation components 503 can simultaneously irradiate and sterilize the inside of the sterilization box 7. Compared with the increased power of a single irradiation component 503, the two irradiation components 503 cooperate to have a higher sterilization efficiency.

[0023] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
