Technical Field

[0001] The utility model relates to the technical field of anhydrous hydrogen fluoride production, and particularly relates to an anhydrous hydrogen fluoride vaporization device. Background Technique

[0002] Hydrogen fluoride is a colorless, pungent-smelling and toxic gas under normal conditions. It has very strong hygroscopicity. When it comes into contact with air, it generates white smoke. It is easily soluble in water and can be infinitely miscible with water to form hydrofluoric acid. During the vaporization process of anhydrous hydrogen fluoride, the internal water vapor needs to be removed.

[0003] For example, a Chinese patent with the patent application number 202223186828.X, an anhydrous hydrogen fluoride vaporization device, can adjust the distance between two desiccant plates through the setting of a dehumidification mechanism. By squeezing the support rod through a hinge plate, the distance between the two desiccant plates is adjusted through internal transmission, and finally the distance that the gas travels between the two desiccant plates changes, thereby making the drying effect better.

[0004] However, when the above patent is actually used, it is not easy to disassemble the desiccant plate, resulting in a large amount of time required to replace the desiccant plate, thus seriously affecting the efficiency of the operator in replacing the desiccant plate.

[0032] Please refer to Figures 1-5 , the present utility model provides a technical solution: an anhydrous hydrogen fluoride vaporization device, including a gasification heating box 1, the bottom of the inner cavity of the gasification heating box 1 is movably connected with a sealing plate 2 through a pushing mechanism, and above the sealing plate 2 inside the gasification heating box 1 is movably connected with a mounting frame 3 through a sliding assembly, and a desiccant plate 4 is fixedly connected inside the mounting frame 3 through a locking mechanism.

[0033] By adopting the above technical solution, the device can quickly remove water and dry the hydrogen fluoride gas through the desiccant plate 4, thereby greatly improving the production efficiency of the device.

[0034] In the embodiment of the present application, as Figure 2 and Figure 5 shown, the pushing mechanism includes a motor 12 installed at the bottom of the gasification heating box 1 and a fixed cylinder 11 installed at the bottom of the inner cavity of the gasification heating box 1. The output end of the motor 12 is fixedly connected with a threaded rod 13. The top of the threaded rod 13 extends into the fixed cylinder 11 and is movably connected with an internal threaded sleeve 14 through a limiting component. The top of the internal threaded sleeve 14 is fixedly connected with the sealing plate 2.

[0035] By adopting the above technical solution, the device can quickly push the sealing plate 2 upward through the pushing mechanism, so that the device can dry all the hydrogen fluoride inside the gasification heating box 1, and further can avoid residual partially undried hydrogen fluoride gas inside the gasification heating box 1 during drying, thereby greatly reducing the waste of hydrogen fluoride gas and greatly improving the drying efficiency of the device.

[0036] In the embodiment of the present application, as Figures 2-4 shown, the locking mechanism includes a plurality of clamping plates 5 installed on the top of the mounting frame 3 and a plurality of insert blocks 6 installed on the outer surface of the desiccant plate 4. A slot 7 is opened on one side of the clamping plate 5, a locking hole 8 is opened inside the insert block 6, a locking rod 9 is arranged inside the locking hole 8, and the top of the locking rod 9 extends above the clamping plate 5.

[0037] By adopting the above technical solution, the device can quickly fix the desiccant plate 4 through the locking mechanism, thus greatly facilitating the installation and disassembly of the desiccant plate 4 by the operator, and further greatly improving the replacement efficiency of the desiccant plate 4 by the operator.

[0038] In an embodiment of the present application, as Figure 3 shown, the sliding assembly includes a plurality of sliding grooves 17 formed in the inner wall of the gasification heating box 1 and a plurality of sliding blocks 18 mounted on the outer surface of the mounting frame 3. The sliding blocks 18 and the sliding grooves 17 are completely sealed.

[0039] By adopting the above technical solution, the position of the mounting frame 3 can be adjusted, so that the device can dry all the residual hydrogen fluoride gas inside the gasification heating box 1.

[0040] In an embodiment of the present application, as Figure 5 shown, the limiting assembly includes limiting grooves 15 formed in the inner walls on both sides of the fixed cylinder 11. A limiting block 16 is movably connected inside the limiting grooves 15, and the other end of the limiting block 16 is fixedly connected to the internal thread sleeve 14.

[0041] By adopting the above technical solution, the limiting assembly is used to make the lifting of the sealing plate 2 more stable.

[0042] In an embodiment of the present application, as Figure 1 shown, a discharge port 20 is fixedly connected to the top of the gasification heating box 1, and a feed port 19 is fixedly connected to one side of the gasification heating box 1.

[0043] By adopting the above technical solution, the device can better perform feeding and air outlet processing.

[0044] In an embodiment of the present application, as Figure 1 shown, support legs 10 are fixedly connected to the four corners of the bottom of the gasification heating box 1.

[0045] By adopting the above technical solution, by the cooperative action of the plurality of support legs 10, the stability of the device is stronger.

[0046] In an embodiment of the present application, as Figure 1 shown, a controller 21 is fixedly connected to the outer surface of the gasification heating box 1.

[0047] By adopting the above technical solution, the controller 21 can be used to more conveniently control the electrical appliances inside the device.

[0048] During use, the operator first passes liquid hydrogen fluoride into the vaporization heating chamber 1 through the feed port 19, then seals the feed port 19, and then starts the heating device inside the vaporization heating chamber 1 through the controller 21 so that it can heat the inside of the vaporization heating chamber 1. When the temperature rises, the liquid hydrogen fluoride will vaporize. At this time, the vaporized gas is dried by the desiccant plate 4 and then discharged into a specific collection device through the discharge port 20, so that this device can quickly remove water from the vaporized hydrogen fluoride gas. After the liquid hydrogen fluoride is completely vaporized, the operator then starts the motor 12 through the controller 21, so that the motor 12 drives the threaded rod 13 to rotate. When the threaded rod 13 rotates, it will drive the internal thread sleeve 14 to move upward under the limiting action of the limiting groove 15 and the limiting block 16, so that the internal thread sleeve 14 can drive the sealing plate 2 to move upward, and then the sealing plate 2 can quickly squeeze the gas inside the vaporization heating chamber 1 upward. When the sealing plate 2 contacts the desiccant plate 4, it will drive the desiccant plate 4 to slide upward along the chute 17. When the internal thread sleeve 14 moves to the highest position, the desiccant plate 4 just contacts the top cover of the vaporization heating chamber 1, so that this device can dry all the hydrogen fluoride inside the vaporization heating chamber 1, and thus can avoid residual partially undried hydrogen fluoride gas inside the vaporization heating chamber 1 during drying, greatly reducing the waste of hydrogen fluoride gas and greatly improving the drying efficiency of this device. When it is necessary to replace the desiccant plate 4, the operator can first open the box cover, then pull out the locking rod 9 from the locking hole 8, then rotate the desiccant plate 4 so that the desiccant plate 4 can drive the plug 6 to disengage from the slot 7, and finally the operator can pull out the desiccant plate 4 upward. Similarly, the operator can quickly install the desiccant plate 4, thus greatly improving the replacement efficiency of the operator for the desiccant plate 4.
