Description

Technical Field

[0001] This utility model relates to the field of yttrium fluoride storage technology, specifically to a yttrium fluoride storage device. Background Technology

[0002] Yttrium fluoride, an important rare earth compound, has wide applications in optical materials, ceramics, and laser technology. Because yttrium fluoride is susceptible to deliquescence and agglomeration, and its chemical properties are unstable in humid environments, its storage requires extremely high levels of moisture protection and sealing. Improper storage conditions can severely affect the purity and performance of yttrium fluoride, reducing its usability and even leading to product spoilage.

[0003] Currently, most yttrium fluoride storage devices on the market adopt traditional sealed tank structures, relying mainly on the mechanical seal between the tank body and the lid to isolate external moisture. However, such devices have significant drawbacks: First, the simple sealing design can only passively block moisture and cannot actively absorb moisture from the storage environment, making it difficult to ensure internal dryness in high humidity environments; second, frequent opening of the tank is required when replacing the desiccant, which is not only cumbersome but also easily allows external moisture to quickly intrude, causing the material to absorb moisture again; third, existing devices lack visual monitoring methods for the moisture absorption status of the desiccant, making it difficult for users to accurately determine whether the desiccant has failed, often requiring opening the tank for inspection, further increasing the risk of the material becoming damp. Utility Model Content

[0004] The purpose of this invention is to provide a yttrium fluoride storage device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a yttrium fluoride storage device, comprising a storage tank, a box body fixedly connected to the top of the storage tank, a strip groove communicating with the interior of the box body on the top of the storage tank, a moisture-proof component provided inside the box body, the moisture-proof component comprising a support plate, the support plate being slidably connected to the interior of the box body, a through groove being provided on the surface of the support plate, a moisture-proof plate being placed on the surface of the support plate, four sets of symmetrically arranged through holes being provided on the surface of the support plate, and a positioning rod being slidably connected in the through holes, one end of the positioning rod being fixedly connected to the top of the storage tank, and the other end of the positioning rod being fixedly connected to a limit block.

[0006] Preferably, the surface of the box body has an inlet, and the inlet is provided with a sealing assembly. The sealing assembly includes a cover plate, an insert plate, and a sealing ring. The insert plate is inserted into the inlet, the cover plate is fixedly connected to the top of the insert plate and fits against the surface of the box body, and the sealing ring is fixedly connected to the outer wall of the insert plate and fits against the inside of the inlet.

[0007] Preferably, a protrusion is fixedly connected to the top of the cover plate.

[0008] Preferably, a scale is fixedly connected to the surface of the support plate, and the scale passes through and is slidably connected to the surface of the box.

[0009] Preferably, the moisture-proof board is elastically connected to the top of the storage tank by a return spring.

[0010] Preferably, the top of the storage tank is provided with an inlet and a cap, and the cap is threadedly connected to the outer wall of the inlet.

[0011] Preferably, the bottom surface of the storage tank is fixedly connected to four sets of symmetrically arranged support legs and a discharge pipe, and the discharge pipe is equipped with a valve.

[0012] Compared with the prior art, the present invention provides a yttrium fluoride storage device, which has the following beneficial effects:

[0013] 1. This yttrium fluoride storage device is connected to the air inside the tank through a channel to actively absorb moisture. At the same time, the threaded seal between the inlet and the cap, as well as the sealing ring at the inlet, form multiple physical barriers to prevent external moisture from entering. This prevents yttrium fluoride from deliquescing and becoming ineffective due to deliquescence during long-term storage in high humidity environments.

[0014] 2. In this yttrium fluoride storage device, the support plate is connected to a scale via a reset spring. When the moisture-proof plate becomes saturated with moisture, its weight increases, causing the support plate to move downwards. The scale displays the position change in real time, allowing for intuitive judgment of when the moisture-proof plate will fail. This avoids the risk of secondary moisture absorption caused by frequent opening of the cover and improves maintenance efficiency. Attached Figure Description

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a yttrium fluoride storage device, including a storage tank 1. The top of the storage tank 1 is provided with an inlet 11 and a cover 12. The cover 12 is threadedly connected to the outer wall of the inlet 11. The inlet 11 is used to add yttrium fluoride powder or granules into the storage tank 1. The cover 12 is fixed to the inlet 11 by threads, providing basic sealing. Four sets of symmetrically arranged support legs 13 and a discharge pipe 14 are fixedly connected to the bottom surface of the storage tank 1. A valve is provided on the discharge pipe 14. The four sets of support legs 13 ensure the stable placement of the storage tank 1, the discharge pipe 14 facilitates the quantitative dispensing of yttrium fluoride, and the valve controls the discharge speed, reducing contact with the outside environment. A box body 2 is fixedly connected to the top of the storage tank 1. A strip groove 3, communicating with the interior of the box body 2, is opened on the top of the storage tank 1. Through the strip groove 3, a moisture-proof component 4 directly acts on the air environment inside the storage tank 1.

[0021] like Figures 1-4 As shown, a moisture-proof component 4 is provided inside the box body 2. The moisture-proof component 4 includes a support plate 41, which is slidably connected to the inside of the box body 2. A through groove 42 is provided on the surface of the support plate 41, and a moisture-proof board 43 is placed on the surface of the support plate 41. The support plate 41 can slide up and down inside the box body 2. The through groove 42 is used for moisture to pass through the support plate 41 and directly contact the moisture-proof board 43, so that the moisture-proof board 43 can effectively absorb the moisture inside the storage tank 1. The surface of the support plate 41 has four sets of symmetrically arranged through holes, and a positioning rod 44 is slidably connected in the through holes. One end of the positioning rod 44 is fixedly connected to the top of the storage tank 1, and the other end of the positioning rod 44 is fixedly connected to a limit block 45. The moisture-proof plate 43 is elastically connected to the top of the storage tank 1 by a return spring 46. A scale 47 is fixedly connected to the surface of the support plate 41. The scale 47 passes through and is slidably connected to the surface of the box 2. The positioning rod 44 is used to position the moisture-proof plate 43, so that the moisture-proof plate 43 can move stably in the vertical direction. The return spring 46 supports the moisture-proof plate 43, so that the moisture-proof plate 43 maintains a certain height inside the box 2. When the moisture absorbed by the moisture-proof plate 43 increases, its weight increases, causing the return spring 46 to gradually compress, thereby driving the support plate 41 to descend. The scale 47 is used to observe the sliding position of the support plate 41, so as to facilitate the judgment of the moisture saturation of the moisture-proof plate 43.

[0022] like Figures 1-4 As shown, an inlet 5 is provided on the surface of the box body 2. A sealing assembly 6 is provided inside the inlet 5. The sealing assembly 6 includes a cover plate 61, an insert plate 62, and a sealing ring 63. The insert plate 62 is inserted into the inside of the inlet 5. The cover plate 61 is fixedly connected to the top of the insert plate 62 and fits against the surface of the box body 2. The sealing ring 63 is fixedly connected to the outer wall of the insert plate 62 and fits against the inside of the inlet 5. A protrusion 64 is fixedly connected to the top of the cover plate 61. By inserting the insert plate 62 into the inlet 5 and the cover plate 61 fitting against the surface of the box body 2, the gap between the inlet 5 and the insert plate 62 is filled by the sealing ring 63, preventing external moisture from entering the inside of the box body 2 through the inlet 5. The protrusion 64 facilitates manual insertion and removal of the insert plate 62, improving operational convenience and facilitating the replacement of the moisture-proof board 43.

[0023] In this invention, during use, the cap 12 is unscrewed, and yttrium fluoride powder or granules are poured into the storage tank 1 through the inlet 11. The cap 12 is then tightened to complete the feeding process.

[0024] During storage, humid air from storage tank 1 enters box 2 through the top slot 3 and contacts moisture-proof plate 43 via the through slot 42 of support plate 41. Moisture-proof plate 43 absorbs moisture from the air, gradually increasing in weight and compressing return spring 46, causing support plate 41 to slide downwards along positioning rod 44. As support plate 41 moves, scale 47 slides synchronously on the surface of box 2, indicating the current position. When scale 47 indicates a threshold close to a preset value (e.g., the lower limit), it indicates that moisture-proof plate 43 is saturated and needs to be replaced.

[0025] When the moisture-proof board 43 needs to be replaced, hold the protrusion 64, pull out the insert plate 62, open the inlet 5, take out the moisture-saturated moisture-proof board 43, and install the dry new moisture-proof board 43, ensuring that it covers the through groove 42 and fits against the support plate 41. Insert the insert plate 62, reseal the inlet 5 with the sealing ring 63, and record the initial position of the scale 47.

[0026] When discharge is required, open the valve of discharge pipe 14 and use gravity to discharge yttrium fluoride from the bottom of the tank. Adjust the flow rate through the valve to achieve quantitative dispensing. After dispensing is completed, close the valve immediately to reduce the amount of air in the tank from the outside.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
