Description

Technical Field

[0001] This utility model relates to the field of gemstone irradiation technology, specifically to a gemstone irradiation device under beam. Background Technology

[0002] Gemstone irradiation, also known as gemstone beam irradiation, is a technique that uses high-energy rays (such as X-rays, gamma rays, and electron beams) to irradiate gemstones, altering their color or optical properties. This technique is commonly used in the jewelry industry to enhance the appearance of gemstones. During irradiation, the gemstone absorbs energy due to the action of high-energy particles, causing its temperature to rise. If not cooled in time, this can lead to overheating, causing cracks and internal structural damage, thus affecting the gemstone's quality and value.

[0003] For example, comparing it with Chinese Patent Publication No. CN218645824U, a spray table for electron irradiation coloring relates to the field of gemstone irradiation coloring technology. The spray table includes a water collection tank and a spray table slidably disposed inside the water collection tank. The water collection tank is also provided with a drive mechanism for driving the spray table to reciprocate. A water spray pipe for spraying water onto the spray table is disposed on the water collection tank and located at the top of the spray table.

[0004] This method can automatically cool irradiated gemstones, reducing labor input, but it is not easy to prevent the effects of low-temperature water ingress on the gemstones. Since gemstones generate heat after irradiation, direct contact with low-temperature water can easily cause cracking due to temperature differences exceeding the acceptable range. Furthermore, while the cooling water's shielding mechanism can absorb radioactive materials and ionization energy during irradiation, cooling via spraying does not ensure complete immersion of the gemstone, leading to fluctuations in cooling effectiveness and potentially causing risks such as air ionization and the spread of radioactive materials. Utility Model Content

[0005] The purpose of this invention is to provide a gemstone irradiation device that can stably immerse gemstones in cooling water and control the temperature of the cooling water within a suitable range, thereby improving the cooling effect and radiation protection effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A beam-guided gemstone irradiation device is provided, including a conveyor belt for supporting the irradiation equipment, a water tank, a gemstone box, a water supply and drainage assembly, and a drive assembly. The water tank is horizontally mounted on the conveyor belt via the drive assembly, and the gemstone box is vertically slidably mounted inside the water tank. The water supply and drainage assembly includes an inlet pipe, an outlet pipe, and a first baffle. The inlet pipe is connected to one end of the water tank, and the outlet pipe is connected to the other end of the water tank. The first baffle is fixedly connected to the inner wall of the water tank and is located between the inlet pipe and the gemstone box. A plurality of through-holes are provided at the bottom of one end of the first baffle.

[0008] Furthermore, the water supply and drainage assembly also includes a second baffle, which is located between the water outlet pipe and the gem box. The second baffle is fixedly connected to the inner wall of the water tank, and the end of the second baffle near the gem box has a wavy structure.

[0009] Furthermore, the bottom wall of the gem box has a mesh structure, the two sides of the gem box are inserted and fitted with the inner wall of the water tank, and the top of the gem box is equipped with multiple screws. The multiple screws pass through the top walls of the two sides of the gem box and are threadedly connected to them. The bottom of the screws abuts against the top of the water tank.

[0010] Furthermore, the drive assembly includes a pair of guide rails that are detachably mounted on the top end of the conveyor belt, multiple rollers that are rotatably mounted on the bottom of the water tank, the outer periphery of the rollers being slidably connected to the top of the guide rails, and multiple support feet that can move vertically mounted on the bottom of the conveyor belt.

[0011] Furthermore, the drive assembly also includes a base plate, a motor, a screw conveyor, a transmission rod, and a limiting mechanism. The base plate is detachably installed at the other end of the top of the conveyor belt. The motor and the screw conveyor are both fixedly installed on the top of the base plate. The output shaft of the motor is coaxially connected to the input end of the screw conveyor. The output end of the screw conveyor is rotatably connected to one end of the transmission rod, and the other end of the transmission rod is fixedly connected to the water tank. The limiting mechanism is installed on the base plate and is used to adjust the stroke of the water tank.

[0012] Furthermore, the limiting mechanism includes a support plate, a pair of limit switches, and sheet metal parts. The bottom of one end of the support plate is fixedly connected to the top of the base plate. The limit switches are horizontally slidably mounted on the support plate. The sheet metal parts are fixedly connected to the periphery of the transmission rod. The sheet metal parts are located between the two limit switches and both ends are inclined structures. A rotating wheel is rotatably connected to one side of the limit switch, and the rotating wheel abuts against the limit switch.

[0013] The beneficial effects of this utility model are as follows: By setting up a water tank, a gem box, and a first baffle, when irradiating gemstones, low-temperature cooling water is injected into the water tank through the water inlet pipe. After entering the water tank, the cooling water is blocked by the first baffle and flows into the gem box through the round hole at the bottom of the first baffle to cool the gemstones. Subsequently, the cooling water overflows the second baffle and flows out through the water outlet pipe. At this time, the water flows over the gemstones at a uniform speed, thereby ensuring the stability of cooling and effectively preventing radioactive materials from spreading into the air. Furthermore, the cooling water is introduced at a low inlet and exited at a high outlet, avoiding the risk of gemstone cracking due to large temperature differences caused by direct contact between the low-temperature water and the gemstone.

[0028] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0029] Reference Figures 1 to 4 The illustrated gemstone irradiation device includes a conveyor belt 1 for supporting the irradiation equipment, a water tank 11, a gemstone box 12, a water supply and drainage assembly 2, and a drive assembly 3. The water tank 11 is horizontally mounted on the conveyor belt 1 via the drive assembly 3, and the gemstone box 12 is vertically slidably mounted inside the water tank 11. The water supply and drainage assembly 2 includes an inlet pipe 20, an outlet pipe 21, and a first baffle 22. The inlet pipe 20 is connected to one end of the water tank 11, and the outlet pipe 21 is connected to the other end of the water tank 11. The first baffle 22 is fixedly connected to the inner wall of the water tank 11 and is located between the inlet pipe 20 and the gemstone box 12. A plurality of through holes 220 are provided at the bottom of one end of the first baffle 22.

[0030] When irradiating gemstones, the gemstones are first placed in a gemstone box 12, and then the gemstone box 12 is inserted into a water tank 11. Low-temperature cooling water is injected into the water tank 11 through the inlet pipe 20. After entering the water tank 11, the cooling water is blocked by the first baffle 22 and flows into the gemstone box 12 through the round hole 220 at the bottom of the first baffle 22 to cool the gemstones. Then, the cooling water flows out from the outlet pipe 21, ensuring that the water flow covers the gemstones and flows at a uniform speed, ensuring that the water surface covers the top of the gemstones by 1 mm, thereby ensuring cooling stability and effectively preventing radioactive materials from spreading into the air. Then, the drive assembly 3 drives the water tank 11 to move horizontally on the conveyor belt 1, while the irradiation equipment is working to irradiate the gemstones. The ends of the inlet pipe 20 and the outlet pipe 21 away from the water tank 11 both have 1 / 4 thread for easy connection to the water supply system.

[0031] Because a large amount of heat is generated during the irradiation process, the water temperature at the top layer of the water tank 11 is higher than that at the bottom layer. The first baffle 22 allows the low-temperature water to flow into the middle of the water tank 11 through the round hole 220. After exchanging heat with the water in the tank to reach a suitable temperature, the water flows upward and comes into contact with the gemstone. This avoids the risk of the gemstone cracking due to the large temperature difference caused by the low-temperature water directly contacting the gemstone, and greatly improves the quality of the gemstone irradiation under the beam.

[0032] like Figure 4 As shown, the water supply and drainage assembly 2 also includes a second baffle 23, which is located between the water outlet pipe 21 and the gem box 12. The second baffle 23 is fixedly connected to the inner wall of the water tank 11, and the end of the second baffle 23 near the gem box 12 has a wavy structure.

[0033] After passing through the first baffle 22, the cooling water flows to the second baffle 23 and impacts it. The end of the second baffle 23 near the gem box 12 has a wave-like structure, which increases the contact area after contacting the water flow and consumes the impact force of the water flow. In addition, the water flow at different positions will have a phase difference due to the difference in the path, thereby canceling each other out to prevent the generation of water waves and avoid affecting the gem irradiation effect.

[0034] In addition, the top of the second baffle 23 is lower than the top of the first baffle 22 but higher than the top of the gemstone, so that the cooling water needs to overflow the second baffle 23 before flowing out of the water tank 11, ensuring that the gemstone is submerged in the cooling water, and allowing the cooling water with a higher temperature at the top of the water tank 11 to flow out first, which can control the cooling water temperature while ensuring a stable water flow.

[0035] like Figure 5 As shown, the bottom wall of the gem box 12 has a mesh structure. The two sides of the gem box 12 are inserted and fitted into the inner wall of the water tank 11. The top of the gem box 12 is provided with multiple screws 120. The multiple screws 120 pass through the top walls of the two sides of the gem box 12 and are threadedly connected to them. The bottom of the screws 120 abuts against the top of the water tank 11.

[0036] First, select gem boxes 12 of different specifications according to the number and size of the gems to be irradiated. Then, place the gems in the gem boxes 12 and insert them into the water tank 11, ensuring that both sides are flush with the inner wall of the water tank 11. At this point, the bottom of the screw 120 is in contact with the top of the water tank 11. Then, rotate the screw 120, adjusting the height of the gem box 12 through the threaded transmission between it and the top wall of the gem box 12, so that the gems are submerged at the appropriate height in the water. The gem box 12 has a frame structure and a mesh structure at the bottom, which allows cooling water to pass through quickly for cooling.

[0037] like Figure 6 and Figure 7As shown, the drive assembly 3 includes a pair of guide rails 30, which are detachably mounted on one end of the top of the conveyor belt 1. Multiple rollers 110 are rotatably mounted on the bottom of the water tank 11. The outer periphery of the rollers 110 is slidably connected to the top of the guide rails 30. Multiple support feet 10 that can move vertically are mounted on the bottom of the conveyor belt 1.

[0038] The drive assembly 3 also includes a base plate 31, a motor 32, a screw elevator 33, a transmission rod 34, and a limiting mechanism 4. The base plate 31 is detachably installed on the other end of the top of the conveyor belt 1. The motor 32 and the screw elevator 33 are both fixedly installed on the top of the base plate 31. The output shaft of the motor 32 is coaxially connected to the input end of the screw elevator 33. The output end of the screw elevator 33 is rotatably connected to one end of the transmission rod 34. The other end of the transmission rod 34 is fixedly connected to the water tank 11. The limiting mechanism 4 is installed on the base plate 31 and is used to adjust the stroke of the water tank 11.

[0039] Adjust the height of the multiple support feet 10 at the bottom of the conveyor belt 1 to a horizontal position using tools such as a spirit level, ensuring that the water tank 11 can move horizontally and thus ensuring uniform irradiation of the gemstones. Power on the motor 32, whose output shaft rotates to drive the screw jack 33 (both motor 32 and screw jack 33 are existing equipment types, such as a 750W rated geared motor 32 (model CH28-20-750W) and an SW2.5 screw jack (model SWL2.5-6-1-A-II-800-FZ), which will not be described in detail here). This, in turn, drives the water tank 11 horizontally via the transmission rod 34. Simultaneously, the rollers 110 at the bottom of the water tank 11 roll along the top of the guide rail 30, further ensuring the horizontal movement of the water tank 11. Furthermore, both the guide rail 30 and the base plate 31 are easily detachable and assembled, allowing the gemstone irradiation device of this invention to be quickly installed on existing conveyor belts 1 for efficient production.

[0040] As shown in Figure 7, the limiting mechanism 4 includes a support plate 40, a pair of limit switches 41, and a sheet metal part 42. The bottom of one end of the support plate 40 is fixedly connected to the top of the base plate 31. The limit switches 41 are horizontally slidably mounted on the support plate 40. The sheet metal part 42 is fixedly connected to the outer periphery of the transmission rod 34. The sheet metal part 42 is located between the two limit switches 41 and both ends are inclined structures. A rotating wheel 410 is rotatably connected to one side of the limit switch 41. The rotating wheel 410 and the limit switch 41 abut against each other.

[0041] When the transmission rod 34 drives the water tank 11 to move horizontally, the sheet metal part 42 moves horizontally along with the transmission rod 34. At both ends of the travel of the sheet metal part 42, it contacts two limit switches 41. Therefore, by moving the position of the limit switches 41, the travel of the water tank 11 can be controlled. Furthermore, with a constant output power of the irradiation equipment, the amount of irradiation received by the gemstone can be easily adjusted, making operation very convenient. Moreover, because both ends of the sheet metal part 42 are inclined surfaces, when it contacts the limit switches 41, its inclined surfaces first contact the rotating wheel 410 at one end of the limit switches 41 and cause it to rotate, thereby reducing the impact force on the sheet metal part 42 and preventing vibration.

[0042] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
