Description

Technical Field

[0001] This application relates to the technical field of crucible structure for titration experiments, and in particular to a splash-proof double-layer titration crucible. Background Technology

[0002] Crucibles are common tools in laboratory smelting and high-temperature chemical reactions. They are placed on a heating platform, and metals are poured into them until they melt. Other metals and chemical reagents are added to test the properties of the alloy at a certain ratio. However, when adding other metals and chemical reagents, splashing of high-temperature liquids can easily occur. To reduce splashing, existing methods involve heating the added metals and chemical titrants to increase their temperature and reduce the risk of splashing at high temperatures. However, in some cases, certain reagents react violently with the properties of metal alloys or metal ion solutions at certain temperatures, and liquid splashing still occurs. Therefore, existing methods often use baffles at the test platform to reduce the danger caused by splashing. In practical applications, physical protection is necessary to improve the experimental process. However, using baffles obstructs personnel operation and makes it difficult to observe and perform other operations. Therefore, a double-layered crucible structure is proposed to solve the existing problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this application is to provide a splash-proof double-layer titration crucible that offers excellent splash protection, does not interfere with other operations on the test bench, effectively improves convenience, and ensures the safe conduct of experiments.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A splash-proof double-layer titration crucible includes: an outer shell, a limiting ring, a limiting side rail, an inner support block, a crucible liner, a movable baffle, a splash-proof top cover, a connecting block, and a vertical tube. The upper end of the outer shell is open, and half of the vertical portion of the outer shell is open. The limiting side rail is located at the lower end of the open side of the outer shell. The inner support blocks are arranged in a circular array on the inner bottom surface of the outer shell corresponding to the inner side of the limiting side rail. The lower end of the movable baffle is fitted between the limiting side rail and the inner support block. The side of the movable baffle is in contact with the open surface of the outer shell. The vertical part of the movable baffle and the outer shell form a cylindrical shape. The limiting ring is set on the bottom surface inside the outer shell. The crucible liner is set inside the limiting ring. The splash-proof top cover is connected to the upper end of the movable baffle and the outer shell. The splash-proof top cover has a through hole in the middle. The lower surface of the splash-proof top cover is arc-shaped. The connecting block is fixedly connected to the outer surface of the middle position of the movable baffle. The vertical tube is fixedly connected to the upper surface of the through hole in the middle of the splash-proof top cover.

[0006] Optionally, it also includes oblique holes, which are inclined downwards from the outside in, and the oblique holes are arranged in a ring array on the surface of the outer shell and the movable baffle at a position slightly above the middle.

[0007] Optionally, it also includes a connecting groove and connecting holes, wherein the connecting groove is formed in the middle of the connecting block and the connecting holes are symmetrically formed on the surfaces of both sides of the connecting block.

[0008] Optionally, a movable handle is also included, which is fixedly connected to the outer surface of the housing at the middle position.

[0009] Optionally, a frosted surface is also included, which is formed on the inner bottom surface of the outer shell corresponding to the inner side of the limiting ring.

[0010] Optionally, it also includes connecting ears, which are symmetrically and fixedly connected to the upper surface of the splash-proof top cover.

[0011] Optionally, it also includes an arc-shaped guide edge, which is disposed at the upper end of the inner support block facing the limiting side rail.

[0012] Optionally, it may also include anti-slip grooves, which are equidistantly formed on the lower surface of the housing.

[0013] This splash-proof double-layer titration crucible, through its combined structure, can block splashed high-temperature liquids. The arc-shaped structure on the lower surface of the splash-proof top cover can maximize the downward reflection of the splashed liquid, preventing it from splashing to the outside.

[0014] This splash-proof double-layer titration crucible also has a vertical tube at the top of the splash-proof top cover. The two work together to further block the flow of liquid with a small vertical angle, greatly reducing the chance of liquid splashing onto people and improving safety performance.

[0015] This splash-proof double-layer titration crucible features a removable baffle and splash-proof top cover, allowing for quick disassembly after testing to remove the inner crucible liner without affecting normal use, thus offering good convenience. Attached Figure Description

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] To better understand the technical solutions presented in the embodiments of this application, the working principle of existing anti-splash titration crucibles will first be introduced.

[0024] Existing crucible materials are broadly categorized into metal crucibles, alumina crucibles, and graphite crucibles, all of which are barrel-shaped. Laboratory-use crucibles have even smaller diameters and are used for heating liquids, molten metals, reagents, etc. However, existing crucible structures are not specifically designed for splash protection. In some cases, crucible lids are used, but this prevents titration operations, and the non-integrated splash protection is ineffective, failing to meet laboratory safety requirements. Current splash protection still relies on the traditional method of adding baffles around the experimental platform, which significantly impacts operational convenience. Therefore, improvements to the existing crucible structure are needed to address these issues.

[0025] Please see Figures 1 to 5 This application discloses a splash-proof double-layer titration crucible, comprising: an outer shell 1, a limiting ring 2, a limiting side rail 3, an inner support block 4, a crucible liner 5, a movable baffle 6, a splash-proof top cover 7, a connecting block 8, and a vertical pipe 9. The upper end of the outer shell 1 is open, and half of the vertical portion of the outer shell 1 is open. The limiting side rail 3 is located at the lower end of the open side of the outer shell 1. The inner support blocks 4 are arranged in a circular array on the inner bottom surface of the outer shell 1 corresponding to the inner side of the limiting side rail 3. The lower end of the movable baffle 6 is connected to the limiting side rail 3 and the inner support block 4. Between them, the two sides of the movable baffle 6 are in contact with the open surface of the side of the outer shell 1. The vertical part of the movable baffle 6 and the outer shell 1 forms a cylindrical shape. The limiting ring 2 is set on the bottom surface inside the outer shell 1. The crucible liner 5 is set inside the limiting ring 2. The splash-proof top cover 7 is connected to the upper end of the movable baffle 6 and the outer shell 1. The middle part of the splash-proof top cover 7 is provided with a through hole. The lower surface of the splash-proof top cover 7 is arc-shaped. The connecting block 8 is fixedly connected to the outer surface of the middle position of the movable baffle 6. The vertical tube 9 is fixedly connected to the upper surface of the through hole in the middle of the splash-proof top cover 7.

[0026] Specifically, the outer shell 1 and the movable baffle 6 form an outer bearing space for placing the inner crucible liner 5. The height of the inner crucible liner 5 is lower than that of the outer shell 1, and the thickness of the inner crucible liner 5 is greater than the thickness of the outer shell 1 and the movable baffle 6. This allows external heat to quickly penetrate into the inner crucible liner 5. The limiting ring 2 supports the placement of the inner crucible liner 5, ensuring it is positioned in the center and is more stable. A gap exists between the limiting side rail 3 and the inner support block 4, allowing the movable baffle 6 to quickly adapt and form a unified structure with the outer shell 1. The inner support blocks 4 are spaced apart to reduce the bottom obstruction area. The splash-proof top cover 7 is relatively thick, and its lower surface is arc-shaped, further preventing splashing. The splashed liquid can be reflected downwards and inwards as much as possible, reducing the chance of it splashing outwards. The vertical tube 9 can also block liquid passing through the through hole in the middle of the anti-splash cover 7, further reducing the chance of liquid splashing out. In rare cases, vertically splashed droplets may occur, but these droplets will be blocked by the burette, burette holder, etc. In other words, with this structure, no additional protective measures are needed around the test bench. Moreover, the assembly and disassembly of this structure are relatively convenient, greatly improving the safety level during operation. The connecting block 8 facilitates the movement of the movable baffle 6 during disassembly. Compared with the existing method of directly covering the crucible with a lid, the double-layer structure increases the internal space, effectively preventing the lid from being pushed away by splashed liquid, resulting in better safety and good practicality.

[0027] Please see Figure 1 As another specific embodiment provided in the application, it also includes oblique holes 10, which are inclined downward from the outside to the inside, and the oblique holes 10 are arranged in a ring array on the surface of the outer shell 1 and the movable baffle 6 at a position slightly above the middle.

[0028] Specifically, the inclined hole 10 facilitates the outward discharge of internal gas when splashing violently, thereby preventing the splash-proof top cover 7 from being pushed, which has good application value. Furthermore, the inclined hole 10 is inclined downward from the outside to the inside, which makes it easier for gas to be discharged. The inclined hole 10 can also prevent liquid from splashing out when splashing.

[0029] Please see Figure 3 As another specific embodiment provided in the application, it also includes a connecting groove 11 and a connecting hole 12. The connecting groove 11 is opened in the middle of the connecting block 8, and the connecting hole 12 is symmetrically opened on the surfaces of both sides of the connecting block 8.

[0030] Specifically, the connection groove 11 helps stabilize the clamp during gripping and increases friction. The connection hole 12 can also be used for disassembly and disassembly of structures such as hooks, improving flexibility during use.

[0031] Please see Figure 1 As another specific embodiment provided in the application, it also includes a movable handle 13, which is fixedly connected to the outer surface of the outer shell 1 at the middle position.

[0032] Specifically, the movable handle 13 is designed to facilitate the transfer of the outer casing 1, and two handles are symmetrically arranged to facilitate stable movement.

[0033] Please see Figure 2 As another specific embodiment provided in the application, it also includes a frosted surface 14, which is formed on the inner bottom surface of the outer shell 1 corresponding to the inner side of the limiting ring 2.

[0034] Specifically, the frosted surface 14 can improve the stability of the crucible liner 5 and enhance its stability during use.

[0035] Please see Figure 4 As another specific embodiment provided in the application, it also includes connecting ears 15, which are symmetrically fixedly connected to the upper surface of the splash-proof top cover 7.

[0036] Specifically, the connection ear 15 facilitates the handling of the splash guard 7.

[0037] Please see Figure 2 As another specific embodiment provided in the application, it also includes an arc-shaped guide edge 16, which is disposed at the upper end of the inner support block 4 on the side facing the limiting side rail 3.

[0038] Specifically, the curved guide edge 16 facilitates placement, making the placement of the movable baffle 6 smoother, positioning faster, and reducing assembly time.

[0039] Please see Figure 5 As another specific embodiment provided in the application, it also includes anti-slip grooves 17, which are equidistantly formed on the lower surface of the outer shell 1.

[0040] Specifically, the anti-slip groove 17 can ensure that the outer shell 1 is placed stably on the heating platform, and can also ensure that the heat is distributed evenly.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
