Description

Technical Field

[0001] This utility model relates to the field of sterilization machine technology, specifically a safety shielding structure for an irradiation sterilization machine. Background Technology

[0002] An irradiation sterilizer is a device that uses high-energy particles (such as gamma rays, electron beams, X-rays, etc.) to disinfect and sterilize items. The main structure of the sterilizer includes a sterilization chamber, with a Teflon mesh belt connected to the bottom of the chamber. The Teflon mesh belt is used to transport items into the sterilization chamber for sterilization. Rubber curtains are fixed at both ends of the sterilization chamber. The rubber curtains can shield radiation without interfering with the passage of items.

[0003] In actual use, there are gaps between adjacent rubber curtains. The Teflon mesh belt carries items directly through the rubber curtain, which can cause some radiation to leak out through the gaps, reducing safety. Furthermore, some items may contain volatile components such as alcohol and fragrances. During gamma irradiation, these components will evaporate and form gases due to the increased temperature. Traditionally, using rubber curtains as a shielding structure does not easily facilitate the exhaust of gases from inside the sterilization chamber. Utility Model Content

[0004] The purpose of this invention is to provide a safe shielding structure for an irradiation sterilizer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A safety shielding structure for an irradiation sterilizer includes:

[0007] Two shielding components are arranged at both ends of the sterilization chamber. Each shielding component includes two guide rails, and a shielding plate is slidably engaged between the two guide rails.

[0008] A drive assembly is arranged above two shielding plates and can drive the two shielding plates to move up and down. The drive assembly includes a motor, and a lead screw is fixed to the output end of the motor. A drive beam is screwed to the outside of the lead screw, and the drive beam is fixedly connected to the shielding plates.

[0009] The first shielding cover is fixed to the outside of a shielding plate and can supply air into the sterilization chamber;

[0010] The second shielding cover is fixed to the outside of another shielding plate and can release the air inside the sterilization chamber;

[0011] Two irregularly shaped tubes are embedded and fixed inside the shielding plate, enabling both shielding cover one and shielding cover two to connect to the sterilization chamber.

[0012] Furthermore, the bottom end of the guide rail is fixed to the sterilization chamber, and two sliders are fixed on the outer side of the shielding plate, which are respectively slidably connected to the guide rail at the corresponding positions.

[0013] Furthermore, a camera is embedded and fixed inside one of the shielding plates, and the height of the shielding plate is greater than the opening height of the sterilization chamber.

[0014] Furthermore, an air inlet pipe is fixedly connected to the outer side of the first shield, and an air outlet pipe is fixedly connected to the outer side of the second shield.

[0015] Furthermore, the irregular tube is designed with multiple bends, and the outside of the irregular tube is wrapped with lead sheet.

[0016] Furthermore, the shielding plate is made of aluminum, and its bottom surface is in contact with the Teflon mesh belt.

[0017] Furthermore, the drive assembly also includes two support panels, each fixed to the sterilization chamber. The top of the two support panels is fixed with a collar that is fixedly connected to the motor, and a diagonal brace is fixed between the support panels and the sterilization chamber.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The motor drives the lead screw to rotate, causing the drive beam, which is screwed to the lead screw, to move down with two shielding plates. This allows the two shielding plates to block the two ends of the sterilization chamber, preventing the radiation inside the sterilization chamber from leaking out. This improves the safety of the sterilizer. By embedding and fixing a camera inside one of the shielding plates, after the two shielding plates block the opening of the sterilization chamber, the user can observe the situation inside the irradiation sterilizer through the image captured by the camera. This allows the user to confirm whether the items being sterilized have received a sufficient radiation dose according to the predetermined procedure.

[0020] 2. By connecting and fixing the external air pumping pipe to the air inlet pipe, air can be supplied to the first shielding cover through the air inlet pipe during the sterilization process. The air is then transported into the sterilization chamber through the special-shaped pipe. The external air suction pipe can be connected and fixed to the air outlet pipe, so that the gas volatilized during sterilization inside the sterilization chamber can be transported into the second shielding cover through another special-shaped pipe and then discharged through the air outlet pipe, thereby achieving the effect of replacing and discharging the sterilization waste gas inside the sterilization chamber.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 5 In this embodiment of the present invention, a safety shielding structure for an irradiation sterilizer includes two shielding components 100. Each shielding component 100 includes two guide rails 110, and a shielding plate 120 is slidably engaged between the two guide rails 110. A driving component 200 is disposed between the upper surfaces of the two shielding plates 120. The driving component 200 includes a motor 210, and a lead screw 220 is fixed to the output end of the motor 210. A driving beam 230 is screwed onto the outer side of the lead screw 220. The driving beam 230 is fixedly connected to the shielding plate 120. A shielding cover 300 and a shielding cover 400 are respectively fixed to the outer sides of the two shielding plates 120. The shielding cover 300 can deliver air into the sterilization chamber. A shaped tube 500 is embedded and fixed inside the shielding plate 120. The two shaped tubes 500 connect the shielding cover 300 and the shielding cover 400 to the sterilization chamber respectively.

[0029] Specifically, by replacing the traditional rubber curtain with a shielding plate 120 made of shielding materials such as lead or aluminum, the shielding plate 120 seals both ends of the sterilization chamber after the items are transported into the sterilization chamber via a Teflon mesh belt. Compared to the rubber curtain, this effectively prevents radiation light from leaking out, improving the safety of the irradiation sterilizer. Shielding cover 300 and shielding cover 400 are fixed to the outside of the two shielding plates 120 respectively. The air inlet pipe 310 supplies air to shielding cover 300, which in turn supplies air into the sterilization chamber through a shaped pipe 500. At the same time, the air outlet pipe 410 exhausts the air inside shielding cover 400, which in turn draws air from the sterilization chamber through another shaped pipe 500. This facilitates the discharge of sterilization exhaust gas from the sterilization chamber, ensuring a clean and tidy sterilization environment.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, the bottom end of the guide rail 110 is fixed to the sterilization chamber, and two sliders 121 are fixed on the outer side of the shielding plate 120, which are respectively slidably connected to the guide rail 110 at the corresponding position. The sliders 121 slide and engage inside the guide rail 110 at the corresponding position, which enables the shielding plate 120 to move stably up and down at both ends of the sterilization chamber. The upward movement of the shielding plate 120 facilitates the external Teflon mesh belt to transport the items into the sterilization chamber, and the downward movement of the shielding plate 120 facilitates the sealing of the sterilization chamber during the sterilization process to prevent radiation leakage.

[0031] like Figure 3 As shown in this embodiment, a camera 122 is embedded and fixed inside a shielding plate 120. The camera 122 can monitor the operating status of the equipment. By observing the inside of the machine, any abnormalities can be detected in time, such as equipment failure or unstable radiation dose, so that timely measures can be taken to deal with them. This saves personnel from having to check the irradiation sterilization situation at close range and prevents adverse effects on the sterilization effect and personnel safety.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the height of the shielding plate 120 is greater than the opening height of the sterilization chamber, and the bottom surface of the shielding plate 120 is in contact with the Teflon mesh belt, so that the opening of the sterilization chamber can be completely covered after the sterilization chamber moves down.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, an air inlet pipe 310 is fixedly connected to the outer side of the shield 1 300, and an air outlet pipe 410 is fixedly connected to the outer side of the shield 2 400. The air inlet pipe 310 can be connected to an external air supply pipe, so that the air inlet pipe 310 supplies air to the sterilization chamber through the shield 1 300. The air outlet pipe 410 is connected to an external air suction pipe, so that the shield 2 400 can suck air from the inside of the sterilization chamber, thereby promoting the flow of gas inside the sterilization chamber.

[0034] In this embodiment, the pipe for supplying or drawing in air from the outside is a flexible hose. The flexible hose can move up and down with the shielding cover 120 without interfering with the shielding cover 300 and shielding cover 400. The pipe for supplying air from the outside can be connected to an exhaust pump to supply air, and the pipe for drawing in air from the outside can be connected to an air extraction pump to extract air. In addition, the exhaust end of the air extraction pump can be connected to an external air purification device to facilitate the purification of the waste gas generated during the sterilization process before it is discharged outdoors.

[0035] like Figure 4 As shown, in this embodiment, the irregular tube 500 is designed with multiple bends, which prevents the radiation from passing through the sterilization chamber in a straight path, thereby achieving a better protective effect. The outer side of the irregular tube 500 is wrapped with lead sheeting to further shield the radiation rays leaking into the irregular tube 500. Furthermore, a shielding cover (including shielding cover 300 and shielding cover 400) is fitted on the outer side of the irregular tube 500 to further prevent the radiation rays from passing through the outer side of the irregular tube 500.

[0036] In this embodiment, the shielding plate 120, shielding cover 300 and shielding cover 400 can all be made of aluminum. Aluminum can serve to shield radiation. Alternatively, other materials that can shield and absorb radiation can be used to prepare the shielding cover and shielding plate 120. The specific material type is selected according to the actual needs of use.

[0037] like Figure 2 and Figure 5 As shown, in this embodiment, the drive assembly 200 also includes two support panels 240 that are fixed to the sterilization chamber. The top of the two support panels 240 is fixed with a collar that is fixedly connected to the motor 210, so that the motor 210 is fixed above the drive beam 230 without affecting the position movement of the drive beam 230. An inclined brace 241 is fixed between the support panel 240 and the sterilization chamber body 610 to further strengthen the stability of the support panel 240 fixed to the top of the sterilization chamber.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the sterilization chamber body 610 is used to sterilize the items, and the Teflon mesh belt body 620 is used to transport the items into the sterilization chamber body 610 and then transport the sterilized items out. This part of the structure is prior art, and the specific working principle will not be described in detail.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
