Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for irradiation sterilization equipment, specifically an accelerator cooling system for irradiation sterilization equipment. Background Technology

[0002] In irradiation sterilization equipment, the tubular accelerator is the core energy output component. During its operation, it generates a large amount of heat due to electron acceleration loss. If this heat cannot be dissipated in time, it will lead to a decrease in accelerator beam quality, accelerated component aging, and even burn-out failure. Currently, the commonly used air-cooling method for tubular accelerators has the following shortcomings: Uneven heat dissipation: Traditional air-cooling devices mostly blow air from a fixed position, which can only dissipate heat to a local area of ​​the accelerator, resulting in large circumferential temperature differences and affecting the stability of accelerator operation; Fixed distance: The distance between the air-cooling components and the accelerator cannot be adjusted. When the accelerator power fluctuates (such as from 10kW to 20kW), the fixed distance is difficult to adapt to the change in heat load. If the distance is too far, the heat dissipation efficiency will be insufficient, and if the distance is too close, the beam accuracy will be easily affected by airflow disturbance.

[0015] Please see Figure 1-4 This utility model provides a technical solution: an accelerator cooling system for irradiation sterilization equipment, including a mounting frame 1 and a tubular accelerator 29. Several sets of mounting plates 2 are fixedly connected to the upper and lower sides of the mounting frame 1 by bolts. A mounting disk 3 is coaxially fixed between two sets of mounting plates 2 by cylindrical head bolts. The mounting disk 3 is a circular metal disk. The tubular accelerator 29 is sleeved inside the mounting disk 3. A radially extending connecting groove 4 is opened on the side of the upper and lower mounting disks 3 facing each other. A first connecting rod 5 is slidably installed inside the connecting groove 4. A connecting box 6 is welded and fixed on the side of the first connecting rod 5 facing each other on both sides. A sliding block 7 is slidably connected inside the connecting box 6. The sliding block 7 is clearance-fitted with the inner wall of the connecting box 6. A second connecting rod 8 is fixedly connected to the side of the sliding block 7 facing each other on both sides by bolts. A cooling box 9 is welded and fixed between the second connecting rods 8. Several sets of air outlets 10 are opened on the side of the cooling box 9 near the tubular accelerator 29. Two sets of air inlet pipes 11 are welded and connected on the side of the cooling box 9 away from the tubular accelerator 29. A rotating ring 12 is sleeved on the outer side of the upper part of the tubular accelerator 29. Several sets of connecting plates 13 are welded and fixed to the outer side of the rotating ring 12 along the circumferential direction. The sets of connecting plates 13 are fixed to the outer side of the upper first connecting rod 5 by countersunk bolts. A toothed ring 14 is welded and fixed to the side of the connecting plate 13 away from the rotating ring 12. A connecting seat 15 is welded and fixed to the lower side of the upper mounting plate 3. A first motor 16 is fixed to the upper part of the connecting seat 15 by bolts. The power end of the first motor 16 penetrates the connecting seat 15 and is fixed to a power gear 17 by a key. The power gear 17 meshes with the toothed ring 14 to form a rotary drive mechanism. The mounting plate 3 has a limiting groove 18 that communicates with the connecting groove 4. The end of the first connecting rod 5 away from the connecting box 6 penetrates into the limiting groove 18 and is welded and fixed with a limiting piece 19. The limiting piece 19 is rotatably installed inside the limiting groove 18. It is a round stainless steel piece with a diameter larger than the width of the connecting groove 4 and smaller than the inner diameter of the limiting groove 18, to prevent the first connecting rod 5 from detaching from the mounting plate 3. The upper connecting box 6 has a sliding rod 20 fixed inside by welding. The sliding rod 20 slides through the through hole of the upper sliding block 7. The inner sides of both ends of the lower connecting box 6 are rotatably connected to threaded rods 21 through bearing seats. The threaded rods 21 are threadedly installed inside the lower sliding block 7. A stainless steel support frame 22 is fixedly connected inside the air intake pipe 11 by screws. A second motor 23 is fixedly connected to the upper part of the support frame 22 by bolts. An exhaust fan 24 is fixedly connected to the power end of the second motor 23 by a coupling. The inner sides of both ends of the intake pipe 11 are fixedly connected with isolation nets 25 by clips to prevent dust and impurities from entering the cooling box 9; A mounting base 26 is welded and fixed to the outside of the lower mounting plate 3. A conductive slip ring 27 is fixedly connected to the upper part of the mounting base 26 by bolts. The stator end of the conductive slip ring 27 is connected to the external power supply wire, and the rotor end is electrically connected to the second motor 23 in the lower connecting box 6 by wire. Two sets of wire holes 28 are opened at the bottom of the lower connecting box 6. The wire passes through the wire holes 28 to avoid the wire from getting tangled when the cooling box 9 rotates.

[0016] Working principle: When this utility model is in use, the power to the first motor 16 is turned on, and the first motor 16 drives the power gear 17 to rotate, which in turn drives the rotating ring 12 to rotate through the gear ring 14. The rotating ring 12 drives the first connecting rod 5 to move in a circular motion along the connecting groove 4 of the mounting plate 3 via the connecting plate 13, thereby driving the connecting box 6 and the cooling box 9 to rotate around the tubular accelerator 29. The power of the second motor 23 is turned on, the exhaust fan 24 rotates, and the external air enters the intake pipe 11 after being filtered by the isolation net 25, then flows into the cooling box 9, and finally blows from the exhaust port 10 towards the tubular accelerator 29 to achieve circumferential air cooling. When the power of the tubular accelerator 29 increases and the air cooling distance needs to be shortened: the lower threaded rod 21 is rotated clockwise, and the threaded rod 21 drives the lower sliding block 7 to slide along the connecting box 6 towards the tubular accelerator 29. The upper sliding block 7 slides synchronously along the sliding rod 20, and the cooling box 9 moves closer to the accelerator along with the second connecting rod 8. When the power of the tubular accelerator 29 decreases and the air cooling distance needs to be increased, the threaded rod 21 is rotated counterclockwise, and the sliding block 7 drives the cooling box 9 away from the accelerator to avoid excessive airflow disturbance to the beam.
