Description

Technical Field

[0001] The utility model relates to the technical field of argon drying, in particular to an argon rapid drying device. Background Art

[0002] The ICP spectrometer is a spectral analysis instrument based on the principle of arc discharge. It requires gas discharge to generate high-temperature plasma to stimulate the emission spectrum of atoms and molecules. Argon, as an inert gas, can provide a stable ionized gas environment, which is conducive to the stable generation and maintenance of plasma. The argon gas in the ICP spectrometer generates a high-temperature plasma environment in the discharge tube, converting the sample to be analyzed into a high-temperature ionized system and causing it to produce an emission spectrum under electromagnetic radiation conditions. At the same time, argon can cool and stabilize ions and atoms in the plasma state. Therefore, the use of argon can effectively improve the analytical performance and stability of the ICP spectrometer, ensuring the analysis precision and accuracy.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1-5 , which is the first embodiment of the present utility model, provides an argon rapid drying device, which includes a drying box 1, a first pipe 31 and a second pipe 32 installed on the top of the drying box 1, and a filter plate 33 located inside the first pipe 31 and the second pipe 32. A support rod 311 is installed at the bottom of the second pipe 32, and the bottom of the support rod 311 is fixedly connected to the drying box 1. A disassembly part 3 is installed on the surface of the first pipe 31 and the second pipe 32. The support rod 311 can position the second pipe 32 and provide support therefor. A handle is installed on the surface of the filter plate 33 for easy removal. An extraction pump for facilitating the extraction of argon gas is installed on one side of the drying box 1.

[0028] The disassembly part 3 includes a card slot 36 opened on the outer surface of the first pipe 31 and the second pipe 32. A first card plate 37 and a second card plate 38 are installed on the outer surface of the first pipe 31 and the second pipe 32 and inside the card slot 36. The first card plate 37 is located on the top of the second card plate 38, and both are semicircular. The first pipe 31 and the second pipe 32 can be clamped together to facilitate the removal of the filter plate 33 and the cleaning of the interior of the first pipe 31 and the second pipe 32. At the same time, it is convenient to install and disassemble the filter plate 33 and clean it.

[0029] Semicircular clamping rings 381 are fixedly connected to the inside of the first clamping plate 37 and the second clamping plate 38. There are two groups of semicircular clamping rings 381, which are respectively located inside the clamping grooves 36 on the outer surfaces of the first pipe 31 and the second pipe 32. In this way, the first pipe 31 and the second pipe 32 can be connected to ensure the stability of the two.

[0030] Screws 39 are movably sleeved on both sides of the first clamping plate 37, and nuts 391 are fixedly connected to the bottoms of both sides of the second clamping plate 38. The screws 39 pass through the first clamping plate 37 and extend to the bottom of the second clamping plate 38 and are threadedly connected to the nuts 391 to achieve the connection between the first clamping plate 37 and the second clamping plate 38.

[0031] The second pipe 32 and the first pipe 31 both have an inner cavity 34 formed therein. The inner diameter of the inner cavity 34 is larger than the outer diameter of the filter plate 33. The filter plate 33 is located inside the inner cavity 34 and is movably connected thereto.

[0032] The surface of the inner cavity 34 is fixedly connected with a positioning rod 35, and the positioning rods 35 are arranged in a ring array. The surface of the filter plate 33 is provided with a groove adapted to the positioning rod 35 to facilitate the initial positioning of the filter plate 33 and the connection of the filter plate 33. The positioning rod 35 is located on the surface of the inner cavity 34 on the inner side of the second pipe 32. The positioning rod 35 is not set inside the first pipe 31, and the filter element 4 is installed inside the drying box 1.

[0033] The filter element 4 includes an activated carbon filter 41 movably connected to the interior of the drying box 1. One end of the activated carbon filter 41 is fixedly connected to a sealing plate 42. A desiccant placement plate 43 is installed at the bottom of the sealing plate 42. The shape of the inner chamber of the desiccant placement plate 43 is set to facilitate the positioning of the desiccant and prevent it from being separated from the desiccant placement plate 43 due to the flow of argon gas. Figure 2 As shown, the diameters of both sides of the activated carbon filter 41 are larger than the diameter of the interior of the drying box 1 , which can provide support therefor. A groove adapted to the activated carbon filter 41 and the desiccant placement plate 43 is provided inside the drying box 1 .

[0034] The top of the sealing plate 42 is fixedly connected to sealing strips 44 arranged at equal distances. The inner side of the sealing plate 42 is fixedly connected to insert strips 45. The insert strips 45 are located on both sides of the activated carbon filter 41. The setting of the sealing strips 44 can prevent argon leakage.

[0035] The filter element 4 also includes a socket 46 opened inside the drying box 1. The insertion strip 45 is located inside the socket 46 and is movably connected thereto, which can facilitate the removal and installation of the activated carbon filter 41 and the desiccant placement plate 43, facilitate the cleaning of the activated carbon filter 41, and facilitate the replacement of the desiccant. A circulation element 5 is installed inside the drying box 1.

[0036] The flow member 5 includes a conical groove 51 and a cylindrical groove 52 opened inside the second pipe 32. There are two groups of conical grooves 51, which are symmetrically arranged at both ends of the cylindrical groove 52, and the three are connected. The internal diameter of the cylindrical groove 52 is smaller than the internal diameter of the second pipe 32, that is, it forms a characteristic of being wide at both ends and narrow in the middle, so as to accelerate the flow rate of the argon gas.

[0037] The circulation member 5 also includes a fan 53 installed inside the drying box 1. The fan 53 is located on the top of the activated carbon filter 41 and at the bottom of the second pipe 32. After passing through the second pipe 32, the argon gas will directly enter the interior of the drying box 1 and slowly drive the fan 53 to rotate, thereby accelerating the circulation of the argon gas to achieve the purpose of rapid drying.

[0038] When the filter plate 33 needs to be cleaned or replaced, first remove the screws 39 to cancel the fixation of the first clamping plate 37 and the second clamping plate 38. Then separate the two to cancel the connection between the first pipe 31 and the second pipe 32. After the two are separated, impurities inside the two can be cleaned. At the same time, the filter plate 33 can be removed by the handle to clean or replace it. In this way, impurities in the filter plate 33 and the first pipe 31 and the second pipe 32 can be easily cleaned, avoiding the problem of reduced argon flow due to excessive impurities.

[0039] When drying the argon gas, the argon gas is transmitted to the interior of the drying box 1 through the first pipe 31. The argon gas is first filtered by the filter plate 33 and transported to the interior of the second pipe 32, passing through the conical groove 51 and the cylindrical groove 52. Due to the characteristics of wide ends and short middle, the argon gas will produce a contraction characteristic when entering the interior of the cylindrical groove 52. When passing through the conical groove 51 at the bottom, the flow cross section increases, and the gas flow rate will directly accelerate and move toward the interior of the drying box 1. At the same time, the impact of the argon gas will drive the fan 53 to rotate. Due to the added effect of the rotating machinery, the kinetic energy generated by the rotor is used to accelerate the flow of the argon gas, thereby increasing the gas flow rate. In this way, the flow speed of the argon gas can be improved, achieving the purpose of rapid transportation.

[0040] The argon gas is then filtered twice through the activated carbon filter 41 to purify the argon gas and make it purer. At the same time, it is dried by the desiccant bag on the surface of the desiccant placement plate 43.

[0041] In summary, the arrangement of the filter plate 33 and the activated carbon filter 41 can make the argon gas purer for use in the ICP spectrometer. At the same time, the arrangement of the disassembly member 3, the insert 45, and the insertion hole 46 can facilitate the cleaning of impurities and avoid the reduction of the argon gas flow caused by impurities.

[0042] By disposing the flow member 5, the flow of the argon gas can be accelerated to achieve the purpose of quickly drying the argon gas.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
