Description

Technical Field

[0001] This utility model relates to the field of high-purity hydrofluoric acid production technology, specifically a high-purity hydrofluoric acid production device. Background Technology

[0002] High-purity hydrofluoric acid is an ultra-clean, high-purity chemical reagent, typically with a purity exceeding 99.99% (metal impurity content below ppm or even ppb). It is primarily used in precision cleaning, etching, and surface treatment processes in high-end manufacturing industries such as semiconductors, photovoltaics, liquid crystal displays (LCDs), and integrated circuits (ICs). Its core characteristics include strong corrosivity (it can dissolve silicon, silica, and metal oxides), high reactivity (it reacts rapidly with a variety of materials), and sensitivity to impurities (even trace amounts of metal ions or particulate contamination can affect product performance). Therefore, production, storage, and transportation must be carried out in a dust-free environment protected by inert gases (such as nitrogen), using corrosion-resistant containers such as polytetrafluoroethylene (PTFE) or high-purity quartz. To obtain high-purity hydrofluoric acid, a high-purity hydrofluoric acid production device is required.

[0003] An investigation revealed that a Chinese utility model patent (CN221433031U) discloses a high-purity hydrofluoric acid production device. The device includes a base and a cavity. The cavity is mounted on the upper surface of the base, and a fixed motor is mounted on the upper surface of the cavity. A fixed rod is mounted on the output end of the fixed motor, extending into the cavity. Multiple stirring rods are mounted on the outer wall of the fixed rod along its circumferential direction. A filter screen is mounted on the inner wall of the cavity, positioned below the fixed rod. A first cylinder is mounted at the bottom of the cavity, and a top plate is mounted on the output end of the first cylinder. Multiple stoppers are mounted on the upper surface of the top plate along its circumferential direction. This utility model employs a filter screen structure to remove impurities from the hydrofluoric acid, and a stopper rod structure to effectively prevent clogging of the screening screen, which could prevent the hydrofluoric acid from being transported.

[0004] The aforementioned patent is not very convenient for users to use and cannot provide easy cleaning, thereby increasing the difficulty of cleaning the preparation device, increasing the overall work complexity, reducing the overall cleaning speed, reducing the overall work efficiency, and slowing down the subsequent work process.

[0005] Therefore, this invention provides a high-purity hydrofluoric acid production device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides a technical solution: a high-purity hydrofluoric acid production device, including a workbench 1, a production frame 2 fixedly connected to the top of the workbench 1, an electric lifting sleeve 3 fixedly connected to the top of the workbench 1, a connecting plate 4 fixedly connected to the top of the electric lifting sleeve 3, a top cover 5 fixedly connected to one side of the connecting plate 4, a mixing motor 6 fixedly connected to the top of the top cover 5, and a mixing stirring column 7 fixedly connected to the output shaft of the mixing motor 6 through a coupling.

[0029] The bottom of the top cover 5 is fixedly connected to an inner connecting plate 8, the bottom of the inner connecting plate 8 is fixedly connected to a filter screen plate 9, the top of the top cover 5 is fixedly connected to an injection threaded pipe 10, and the outer wall of the injection threaded pipe 10 is movably connected to an injection threaded lock 11. This makes the high-purity hydrofluoric acid production device more convenient to use, thereby reducing the cleaning difficulty of the production device, reducing the overall work complexity, improving the overall cleaning speed, improving the overall work efficiency, and accelerating the subsequent work process.

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: a liquid extraction pipe 12 is fixedly connected to the bottom of the manufacturing frame 2, and a liquid extraction device 13 is fixedly connected to one end of the liquid extraction pipe 12 to facilitate quick extraction of the materials made in the manufacturing frame 2. A liquid outlet threaded pipe 14 is fixedly connected to the bottom of the liquid extraction device 13, and a liquid outlet threaded lock 15 is movably connected to the outer wall of the liquid outlet threaded pipe 14 to facilitate locking with an external collection pipe.

[0031] The bottom of the workbench 1 is fixedly connected to an electric lifting base plate 16, and there are two electric lifting base plates 16, which can adjust the overall working height of the device. The bottom of the electric lifting base plate 16 is fixedly connected to a base 17, and the bottom area of ​​the base 17 is larger than the bottom area of ​​the electric lifting base plate 16, which improves the overall working stability of the device.

[0032] The outer wall of the injection threaded tube 10 is movably connected to the inner wall of the injection threaded lock 11, and there are two injection threaded tubes 10 and two injection threaded locks 11, which can be locked to the external injection pipe.

When the anhydrous hydrogen fluoride and potassium permanganate solution are injected into the production frame 2, the mixing motor 6 starts to work. The output shaft of the mixing motor 6 rotates, causing the mixing and stirring column 7 to rotate, thereby allowing the anhydrous hydrogen fluoride to be injected into the mixture. High-purity hydrofluoric acid is produced by mixing with potassium permanganate solution. After mixing, the pumping device 13 operates to extract the high-purity hydrofluoric acid from the production frame 2 through the pumping pipe 12 and transport it to the collection outer pipe. The filter screen 9 will filter out impurities. If it is necessary to clean the inside of the device, the electric lifting sleeve 3 is raised so that the filter screen 9, the inner connecting plate 8 and the mixing and stirring column 7 are raised above the production frame 2. At that time, the production frame 2, the mixing and stirring column 7, the inner connecting plate 8 and the filter screen 9 can be cleaned quickly.
