Description

Technical Field

[0001] The present invention relates to the technical field of irradiation equipment, and in particular to an alarm device for irradiation equipment. Background Art

[0002] An irradiation device is composed of an irradiation chamber, an irradiation source, a transmission device, an installation facility, a control system, etc., and is a device for realizing a safe and reliable radiation processing technology. Irradiation sterilization is an effective method of using ionizing radiation to generate electromagnetic waves to kill microorganisms on most substances. The rays used for sterilization include electron beams, X-rays, γ-rays, etc. They can all control the growth of microorganisms or kill microorganisms through specific methods. Commonly used irradiation sterilization equipment is installed in a designated irradiation chamber during use, and the scanning box of the irradiation equipment is installed above the conveyor belt, and the materials on the conveyor belt are irradiated and sterilized by the rays emitted by the scanning box.

[0003] Commonly used irradiation equipment is installed in a designated irradiation chamber, and because the rays are harmful to the human body, the personnel around the irradiation equipment in the irradiation chamber cannot approach. When the radiation dose is large or the irradiation angle of the rays emitted by the scanning box deviates during the use of the irradiation equipment, the commonly used irradiation equipment cannot give an alarm to the outside in time, and the irradiation equipment cannot adjust the position of the scanning box according to the volume of the materials to be sterilized, resulting in that when the volume of the materials is large, the rays irradiated by the scanning box of the upper irradiation equipment cannot irradiate and sterilize the materials well. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose an alarm device for irradiation equipment.

[0007] Preferably, glass plates are installed on the four inner walls of the installation frame. On the side of the glass plate close to the inside of the installation frame, a number of second irradiation intensity detection sheets are installed in the length direction. Second connecting plates are installed at positions close to both ends of the arc plate on both installation plates. The first irradiation intensity detection sheet, the second irradiation intensity detection sheet, and the irradiation sensing sheet are all electrically connected to a number of alarm lights through the second connecting plate and the first connecting plate.

[0008] Preferably, one end of the installation frame is located inside the arc plate. A protective plate is installed on the side of the installation plate close to the alarm light. The protective plate is slidably installed on the side of the arc plate. A pulse transformer is installed at the bottom of the installation plate away from the protective plate.

[0009] Preferably, one end of the top of the pulse transformer is installed at the bottom of the installation plate, and a klystron is installed at the other end of the top of the pulse transformer. An accelerating tube is installed in the installation frame in the length direction. A waveguide is installed on the outer wall of the klystron. One end of the waveguide penetrates the glass plate and is connected to the accelerating tube.

[0010] Preferably, an electron gun is installed at the top end of the accelerating tube, and a focusing coil is installed on the outer wall of the accelerating tube below the electron gun. The electron gun and the focusing coil are both located inside the installation frame.

[0011] Preferably, the bottom end of the accelerating tube penetrates the installation frame and is installed with a scanning magnet. The scanning magnet is installed at the bottom of the installation frame. One end of the scanning magnet away from the installation frame is installed with a scanning box. The scanning box and the scanning magnet are both located inside the arc plate.

[0012] Preferably, an electric slider is installed at one end of the pulse transformer close to the arc plate. The electric slider is slidably installed inside the sliding hole. The waveguide is located above the electric slider.

[0013] Preferably, limiting plates are installed on both sides of the conveying plate. The two limiting plates are respectively slidably installed at both ends inside the installation holes. One end of the limiting plate away from the conveying plate penetrates the installation hole and is installed with a fixing plate. The two fixing plates are respectively slidably installed on the outer walls at both ends of the arc plate.

[0014] Preferably, screw holes are opened on the outer walls at both ends of the arc plate, and a number of fixing holes are opened on the side of the fixing plate. A fixing bolt is installed in one of the fixing holes, and one end of the fixing bolt is threadedly installed in the screw hole.

[0015] Preferably, an annular placement groove is opened on the outer wall of the conveying plate. A conveyor belt is slidably installed inside the placement groove. The conveyor belt is located between the two first irradiation intensity detection sheets.

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

[0017] 1. When the height of the materials in the present invention is relatively low, the rays irradiated by the scanning box near the upper part of the materials will be obliquely irradiated from above the materials onto the irradiation sensing sheets on the inner walls on both sides of the arc-shaped plate, and the rays irradiated by the scanning box near the conveying plate will be irradiated onto the top of the first irradiation intensity detection sheet on the top side of the conveying plate. When the first irradiation intensity detection sheet detects that the irradiation dose of the irradiated rays is relatively large, several alarm lights near one end of the side of the arc-shaped plate will gradually light up. During use, the number of lit alarm lights is adjusted according to the irradiation dose detected by the first irradiation intensity detection sheet. At the same time, the alarm lights emit an alarm bell. When a large amount of irradiated rays are irradiated on the surface of the irradiation sensing sheet due to the low height of the materials, the irradiation sensing sheet will detect the irradiated ray area on its surface and make the alarm lights light up in a specified color through the first connecting plate, and the staff can then adjust the rotation angle of the mounting frame and the scanning box again through the electric slider.

[0018] 2. Glass plates are installed on the four inner walls of the mounting frame in the present invention. The glass plates can play a good protective role for the inside of the mounting frame, preventing external dust from entering the inside of the mounting frame, and also preventing external objects from colliding with the inside of the mounting frame, and facilitating the staff to observe the inside of the mounting frame through the glass plates. During use, when the acceleration tube is damaged and the transported electron beam leaks, several second irradiation intensity detection sheets on the inner wall of the glass plate can detect the space inside the mounting frame in real time. When the radiation dose inside the mounting frame is relatively large, several alarm lights are sequentially lit through the second connecting plate and the first connecting plate, and an alarm bell is emitted, facilitating the staff to quickly turn off the external power supply and perform maintenance.

[0019] 3. During use, the staff can drive the pulse transformer and the scanning box to move through the electric slider according to the usage situation, so that the two mounting frames are respectively moved to the upper sides on both sides of the conveying plate. When the two mounting frames move, the two scanning boxes can be respectively rotated to the upper sides on both sides of the materials, so that the two scanning boxes irradiate the positions near the corners on both sides of the top of the materials. During use, the same scanning box can irradiate the side and the top of the materials simultaneously. When the two scanning boxes are used in cooperation, they can irradiate and sterilize the top and both sides of the materials simultaneously, making the sterilization effect of the materials better.

[0020] 4. The staff can adjust the height of the conveying plate located inside the arc-shaped plate according to the volume of the materials transported on the top of the conveying plate in the present invention, preventing the top of the materials from being too close to the inner top of the arc-shaped plate due to the large volume of the materials during use, so that the scanning box cannot irradiate and sterilize the materials comprehensively during use. The fixing bolts connect the arc-shaped plate and the fixing plate. During use, the conveying plate can play a good position fixing role for the arc-shaped plate through the limiting plate and the fixing plate, making the arc-shaped plate more stable during use.

Detailed Description of the Invention

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0032] Referring to Figure 1-8 , an alarm device for an irradiation device, comprising a conveying plate 1, an arc plate 2 is installed above the conveying plate 1, both ends of the arc plate 2 are movably installed on both sides of the conveying plate 1 respectively, an arc-shaped sliding hole 12 is formed on the side surface of the arc plate 2, mounting holes 13 are formed on the outer wall of the arc plate 2 in the length direction, the mounting holes 13 penetrate through the sliding hole 12 and the arc plate 2, irradiation sensing sheets 20 are installed on both sides of the inner wall of the arc plate 2 in the length direction, first irradiation intensity detection sheets 11 are installed on both sides of the top of the conveying plate 1 in the length direction, a plurality of alarm lights 14 are installed on the side surface of the arc plate 2, first connecting plates 15 are installed at both ends of the side surface of the arc plate 2, mounting plates 3 are slidably installed at both ends of the outer wall of the arc plate 2, a through hole is formed on the side surface of the mounting plate 3, and a mounting frame 4 is installed on the inner wall of the through hole.

[0033] As a technical optimization scheme of the present invention, glass plates 19 are installed on the four inner walls of the mounting frame 4, a plurality of second irradiation intensity detection sheets 28 are installed on the side close to the inside of the mounting frame 4 in the length direction, second connecting plates 24 are installed at positions of both mounting plates 3 close to both ends of the arc plate 2, and the first irradiation intensity detection sheets 11, the second irradiation intensity detection sheets 28 and the irradiation sensing sheets 20 are electrically connected to the plurality of alarm lights 14 through the second connecting plates 24 and the first connecting plates 15 respectively; when in use, the two first connecting plates 15 are respectively connected to the second irradiation intensity detection sheets 28 inside the two mounting frames 4, the first irradiation intensity detection sheets 11 on both sides of the top of the conveying plate 1 and the two irradiation sensing sheets 20 on both sides inside the arc plate 2. When the irradiation intensity is too high and the irradiation is irradiated on the irradiation sensing sheets 20 in a large area, the plurality of alarm lights 14 will light up in sequence from both ends of the side surface of the arc plate 2 to the middle position of the arc plate 2 according to the irradiation intensity. The higher the irradiation intensity, the more the number of alarm lights 14 that light up.

[0034] As a technical optimization scheme of the present invention, one end of the mounting frame 4 is located inside the arc plate 2, a protection plate 23 is installed on the side surface of the mounting plate 3 close to the alarm light 14, the protection plate 23 is slidably installed on the side surface of the arc plate 2, and a pulse transformer 16 is installed at the bottom of the mounting plate 3 far from the protection plate 23; the protection plate 23 and the pulse transformer 16 cooperate with each other to play a better role in positioning the arc plate 2 and can play a better stabilizing role for the mounting plate 4 when in use.

[0035] As a technical optimization solution of the present invention, one end of the top of the pulse transformer 16 is mounted on the bottom of the mounting plate 3, and a klystron 18 is mounted on the other end of the top of the pulse transformer 16. An accelerating tube 27 is mounted inside the mounting frame 4 in the length direction. A waveguide 25 is mounted on the outer wall of the klystron 18. One end of the waveguide 25 penetrates through the glass plate 19 and is connected to the accelerating tube 27. The glass plate 19 can play a good protective role for the inside of the mounting frame 4 during use, preventing radiation leakage inside the mounting frame 4 during use.

[0036] As a technical optimization solution of the present invention, an electron gun 30 is mounted at the top end of the accelerating tube 27, and a focusing coil 29 is mounted on the outer wall of the accelerating tube 27 below the electron gun 30. Both the electron gun 30 and the focusing coil 29 are located inside the mounting frame 4. The accelerating tube 27 can convey the electron beam during use.

[0037] As a technical optimization solution of the present invention, the bottom end of the accelerating tube 27 penetrates through the mounting frame 4 and is mounted with a scanning magnet 22. The scanning magnet 22 is mounted on the bottom of the mounting frame 4. One end of the scanning magnet 22 away from the mounting frame 4 is mounted with a scanning box 17. Both the scanning box 17 and the scanning magnet 22 are located inside the arc-shaped plate 2. The scanning box 17 can irradiate the surface of the materials conveyed on the conveying plate 1 with radiation rays during use, and sterilize the materials through the irradiation of the radiation rays.

[0038] As a technical optimization solution of the present invention, an electric slider 26 is mounted at one end of the pulse transformer 16 close to the arc-shaped plate 2. The electric slider 26 is slidably mounted inside the sliding hole 12, and the waveguide 25 is located above the electric slider 26. During use, the staff can adjust the positions of the two mounting plates 3 and the mounting frame 4 through the electric slider 26 according to the use situation, which is convenient for the staff to irradiate the materials in different angular directions.

[0039] As a technical optimization solution of the present invention, limit plates 7 are mounted on both sides of the conveying plate 1. The two limit plates 7 are respectively slidably mounted at both ends inside the mounting holes 13. One end of the limit plate 7 away from the conveying plate 1 penetrates through the mounting hole 13 and is mounted with a fixing plate 8. The two fixing plates 8 are respectively slidably mounted on the outer walls at both ends of the arc-shaped plate 2. During use, the conveying plate 1 can play a good role in limiting the position of the arc-shaped plate 2 through the two fixing plates 8, making the arc-shaped plate 2 more stable during use.

[0040] As a technical optimization solution of the present invention, screw holes 21 are provided on the outer walls at both ends of the arc-shaped plate 2, and a plurality of fixing holes 9 are provided on the side surface of the fixing plate 8. A fixing bolt 10 is installed in one of the fixing holes 9, and one end of the fixing bolt 10 is threadedly installed in the screw hole 21; during use, the staff can adjust the height of the conveying plate 1 inside the arc-shaped plate 2 according to the usage situation, which is convenient for the staff to irradiate and sterilize materials of different volumes on the conveying plate 1 to better irradiate the materials comprehensively.

[0041] As a technical optimization solution of the present invention, an annular placement groove 5 is provided on the outer wall of the conveying plate 1, and a conveyor belt 6 is slidably installed inside the placement groove 5. The conveyor belt 6 is located between two first irradiation intensity detection pieces 11; during use, the staff can place the materials to be sterilized on the top of the conveyor belt 6, and both ends of the conveyor belt 6 are connected to external transmission equipment. When the conveyor belt 6 moves, it can drive the materials to move inside the arc-shaped plate 2 for irradiation and sterilization.

[0042] When the present invention is in use, the staff installs the arc-shaped plate 2 above the conveying plate 1, and both ends of the arc-shaped plate 2 are respectively located on both sides of the conveying plate 1. During use, the staff can adjust the height of the conveying plate 1 inside the arc-shaped plate 2 according to the volume of the materials conveyed on the top of the conveying plate 1, so as to prevent the volume of the materials from being too large during use, resulting in the top of the materials being too close to the inner top of the arc-shaped plate 2, so that the scanning box 17 cannot irradiate and sterilize the materials comprehensively during use. After the staff adjusts the height of the conveying plate 1, the fixing holes 9 on the fixing plate 8 are connected to the screw holes 21 at both ends of the arc-shaped plate 2, and the staff can connect the arc-shaped plate 2 and the fixing plate 8 through the fixing bolts 10. During use, the conveying plate 1 can play a good position-fixing role for the arc-shaped plate 2 through the limiting plate 7 and the fixing plate 8, making the arc-shaped plate 2 more stable during use.

[0043] When in use, the limiting plates 7 located on both sides of the conveying plate 1 are slidably installed inside the mounting holes 13 on the arc-shaped plate 2. When in use, the limiting plates 7 cooperate with the fixing bolts 10 to fix the position of the arc-shaped plate 2 well and prevent the top of the arc-shaped plate 2 from shaking during use. After the staff finishes installing the arc-shaped plate 2, the staff can install the two mounting frames 4 at both ends inside the mounting holes 13 of the arc-shaped plate 2. When in use, the mounting frames 4 are installed in the through holes on the mounting plate 3, and the mounting plate 3 is slidably installed on the outer wall of the arc-shaped plate 2. When in use, the arc-shaped plate 2 can limit the position of the mounting frames 4 through the mounting plate 3, so that the length of the end of the mounting frame 4 located inside the arc-shaped plate 2 is always the same. At the same time, the second connecting plate 24 on the side of the mounting plate 3 is connected to the first connecting plate 15 on the side of the arc-shaped plate 2 during use, and the two first connecting plates 15 are respectively connected to a plurality of warning lights 14 at both ends of the side of the arc-shaped plate 2. At the same time, the irradiation sensing sheet 20 on the inner wall of the arc-shaped plate 2 and the first irradiation intensity detection sheets 11 on both sides of the top of the conveying plate 1 are connected to the first connecting plate 15.

[0044] When in use, the protective plate 23 at one end of the mounting plate 3 is slidably installed on one side of the arc-shaped plate 2, and the pulse transformer 16 at the other end of the mounting plate 3 is slidably installed on the other side of the arc-shaped plate 2. When in use, the protective plate 23 can cooperate with the pulse transformer 16 to clamp and position the arc-shaped plate 2, making the mounting plate 3 more stable when sliding on the outer wall of the arc-shaped plate 2. At the same time, it also prevents the situation that when the mounting frame 4 moves to both ends of the outer wall of the arc-shaped plate 2, one end of the mounting frame 4 close to the arc-shaped plate 2 tilts or falls due to its own weight.

[0045] When in use, both ends of the conveyor belt 6 on the conveying plate 1 are connected to external transmission equipment, and the conveyor belt 6 is driven by the transmission equipment to move in the placement groove 5 on the conveying plate 1. The staff places the materials to be sterilized on the top of one end of the conveyor belt 6, and when the conveyor belt 6 moves, it can drive the materials to move into the arc-shaped plate 2. When in use, the electron rays generated by the pulse transformer 16 are transmitted to the inside of the accelerating tube 27 through the klystron 18 and the waveguide 25, and are irradiated on the surface of the materials through the scanning box 17. When in use, the materials can be irradiated and sterilized.

[0046] During use, the staff can drive the pulse transformer 16 to move towards one end of the arc-shaped plate 2 according to the usage situation through the electric slider 26. When the pulse transformer 16 moves, it can drive the mounting plate 3 and the mounting frame 4 to move. During use, the two mounting frames 4 can be respectively moved to both sides above the conveying plate 1. When the two mounting frames 4 move, the two scanning boxes 17 can be respectively rotated to both sides above the material, so that the two scanning boxes 17 irradiate the positions near the corners on both sides of the top of the material. During use, the same scanning box 17 can irradiate the side and the top of the material simultaneously. The two scanning boxes 17 cooperate with each other during use and can irradiate and sterilize the top and both sides of the material simultaneously, making the sterilization effect of the material better.

[0047] During use, the scanning box 17 will emit a number of thin rays, which only cover and irradiate the surface of the material. When the two scanning boxes 17 are respectively rotated to both sides above the material and irradiate and sterilize the material, and the height of the material is relatively low, because the width of the rays emitted by the scanning box 17 will become wider as the irradiation distance becomes farther, and the range irradiated by the rays will gradually become wider, so the rays near the material above irradiated by the scanning box 17 will be obliquely irradiated on the irradiation sensing sheets 20 on the inner walls of both sides of the arc-shaped plate 2 from above the material, and the rays near the conveying plate 1 irradiated by the scanning box 17 will irradiate the top of the first irradiation intensity detection sheet 11 on the side of the top of the conveying plate 1.

[0048] During use, the first irradiation intensity detection sheet 11 can detect the radiation dose of the irradiated rays in real time. When the first irradiation intensity detection sheet 11 detects that the irradiation dose of the irradiated rays is relatively large, several alarm lights 14 at one end of the arc-shaped plate 2 close to the scanning box 17 irradiating the first irradiation intensity detection sheet 11 will gradually light up. During use, the number of the lit alarm lights 14 is adjusted according to the irradiation dose detected by the first irradiation intensity detection sheet 11. When the irradiation dose is relatively large, several alarm lights 14 will gradually light up from one end close to the first connecting plate 15 to the middle end of the arc-shaped plate 2, and at the same time, the alarm lights 14 will emit an alarm bell.

[0049] When a large amount of irradiation rays irradiate on the surface of the irradiation sensing sheet 20 due to the relatively low height of the material, the irradiation sensing sheet 20 will detect the area of the irradiated rays on its surface, and make the alarm lights 14 light up in a specified color through the first connecting plate 15. Then the staff can adjust the rotation angle of the mounting frame 4 and the scanning box 17 again through the electric slider 26, so that the scanning box 17 can irradiate and sterilize the surface of the material more comprehensively during use.

[0050] During use, glass plates 19 are installed on the four inner walls of the installation frame 4. The glass plates 19 can provide good protection for the interior of the installation frame 4, preventing dust from the outside from entering the interior of the installation frame 4, and at the same time preventing external objects from colliding with the interior of the installation frame 4. Also, it is convenient for the staff to observe the interior of the installation frame 4 through the glass plates 19. During use, when the acceleration tube 27 is damaged, resulting in the leakage of the electron beam being transported, several second irradiation intensity detection pieces 28 on the inner wall of the glass plate 19 can detect the space inside the installation frame 4 in real time. When the radiation dose inside the installation frame 4 is relatively large, several alarm lights 14 are sequentially lit through the second connecting plate 24 and the first connecting plate 15, and a warning bell is sounded, facilitating the staff to quickly turn off the external power supply and perform maintenance.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
