Description

Technical Field

[0001] The utility model relates to the technical field of argon purification, and specifically relates to an argon purification and refining device. Background Art

[0002] Argon is an inert noble gas widely used. It has the properties of non-combustion and non-supporting combustion, making it widely used in argon arc welding, bulb filling, and soundproof glass. Due to different application fields of equipment, the purity of argon used in equipment in different fields varies. The argon used in precision instruments needs to be purified by a purification device to keep it within a high-purity range.

[0003] An existing publicly disclosed argon fractionation and purification device includes a fractionation flask. A heat exchanger is arranged on the lower side of the fractionation flask. A heat exchange groove corresponding to the fractionation flask is opened on the heat exchanger, and a clamping mechanism corresponding to the fractionation flask is arranged on the heat exchanger. A gas guide pipe is fixedly communicated with the upper end side wall of the fractionation flask. One end of the gas guide pipe away from the fractionation flask is fixedly provided with a connecting pipe, and the connecting pipe is fixedly arranged on the gas guide pipe through a fixing mechanism. The utility model can quickly stabilize the fractionation flask on the heat exchanger, avoid the problem that the fractionation flask topples and affects fractionation, and can tighten the connection between the gas guide pipe and the connecting pipe to avoid gaps causing argon leakage, effectively avoiding waste of argon resources.

[0004] In the above-mentioned prior art, through the cooperation of the fractionation flask and the heat exchanger, the argon in the fractionation flask is fractionated and purified, so that the impurities in the argon can be removed, and the purity of the argon can reach the use requirements. However, the speed of purifying argon by the fractionation flask and the heat exchanger is slow, and only a small amount of argon can be purified each time, resulting in low production efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an argon purification and refining device to solve the above problems.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An argon purification and refining device includes:

[0007] A purification box, and a condensation box is fixedly installed on the side wall of the purification box;

[0008] Getter layers symmetrically arranged in the purification box;

[0009] An air inlet pipe fixedly installed on the side wall of the condensation box and extending into the purification box;

[0010] A condensation assembly, which at least includes a condensation pipe fixedly installed in the condensation box and arranged around the side wall of the air inlet pipe.

[0011] Preferably, the condenser tube is provided with spray heads arrayed along the tube wall of the condenser tube.

[0012] Preferably, a recovery box is fixedly installed at the bottom end of the condensation box, and the recovery box is communicated with the condensation box.

[0013] Preferably, a flow guide plate is fixedly installed in the air inlet pipe, a collection plate is movably installed in the air inlet pipe, and one end of the collection plate abuts against the flow guide plate.

[0014] Preferably, a heating chamber is fixedly installed at the bottom end of the purification box, a heating sheet is fixedly installed in the heating chamber, and a glass plate is fixedly installed at the top end of the heating chamber.

[0015] Preferably, an air outlet pipe is fixedly installed at the top end of the purification box.

[0016] Preferably, an exhaust fan is fixedly installed at the bottom end of the air outlet pipe, and an argon filter membrane is fixedly installed at the air outlet of the exhaust fan.

[0017] In the above technical solution, an argon purification and refinement device provided by the present utility model has the following beneficial effects: By connecting a gas cylinder filled with argon to the air inlet pipe by a worker, the gas cylinder flows along the air inlet pipe into the purification box. During the process of flowing into the purification box, the argon passes through the condensation box. By continuously pouring a condensation liquid into the condenser tube, the condenser tube cools the temperature in the condensation box, so that the temperature of the air inlet pipe in the condensation box drops to -100°C. When the temperature of the air inlet pipe drops to a predetermined temperature, impurities in the argon with a condensation point lower than -100°C will quickly condense and separate from the argon, thus achieving the purpose of the first purification of the argon. When the argon passes through the air inlet pipe and enters the purification box, since the temperature in the purification box is higher than 0°C, the low-temperature argon quickly heats up and expands. When the argon expands and diffuses throughout the purification box, an absorbent layer installed in the purification box filters the argon for the second time, so that trace impurities in the argon react with the absorbent and separate from the argon. This not only solves the problem of slow purification efficiency of the fractionating flask, but also can continuously filter a large amount of argon, greatly improving the filtration efficiency.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figure 1-2 shown, an argon purification and refining device includes;

[0025] A purification box 2, and a condensation box 1 is fixedly installed on the side wall of the purification box 2;

[0026] Getter layers 11 symmetrically arranged in the purification box 2;

[0027] An intake pipe 5 fixedly installed on the side wall of the condensation box 1 and extending into the purification box 2;

[0028] A condensation assembly, which at least includes a condensation tube 3 fixedly installed in the condensation box 1 and arranged around the side wall of the intake pipe 5.

[0029] Specifically, the argon to be purified is input into the purification box 2 through the intake pipe 5, so that the argon can enter the purification box 2 for purification. During the flow of the argon along the intake pipe 5, by continuously pouring a refrigerant into the condensation tube 3, the temperature in the condensation box 1 is reduced to -100°C by the condensation tube 3, and since the condensation tube 3 is arranged around the side wall of the intake pipe 5, the temperature of the intake pipe 5 is quickly reduced to -100°C, thereby quickly reducing the temperature of the argon in the intake pipe 5. When the argon drops to -100°C, the impurities in the argon with a condensation point lower than -100°C will quickly condense and separate from the argon, completing the first filtration of the argon. When the cooled argon passes through the intake pipe 5 and enters the purification box 2, since the temperature in the purification box 2 is higher than 0°C, the -100°C argon quickly warms up, causing the argon to quickly expand and flow towards the air outlet of the purification box 2. During the flow of the argon, the two fixedly installed getter layers 11 perform a secondary filtration on the argon, so that the trace impurities in the argon are absorbed by the getter, thereby improving the purity of the argon. This not only improves the argon purification efficiency but also enhances the argon purification effect.

[0030] In the above embodiments, a worker connects a gas cylinder filled with argon to the inlet pipe 5, causing the gas cylinder to flow along the inlet pipe 5 into the purification tank 2. During the flow of argon into the purification tank 2, it passes through the condensation tank 1. By continuously pouring the condensation liquid into the condensation pipe 3, the condensation pipe 3 cools down the temperature in the condensation tank 1, so that the temperature of the inlet pipe 5 in the condensation tank 1 drops to -100°C. When the temperature of the inlet pipe 5 drops to the predetermined temperature, the impurities in argon with a condensation point lower than -100°C will quickly condense and separate from the argon, thus achieving the purpose of the first purification of argon. When the argon passes through the inlet pipe 5 and enters the purification tank 2, since the temperature in the purification tank 2 is the same as the indoor temperature, the low-temperature argon quickly heats up and expands. When the argon expands and diffuses throughout the purification tank 2, the getter layer 11 installed in the purification tank 2 filters the argon for the second time, causing the trace impurities in the argon to react with the getter and separate from the argon. This not only solves the problem of slow purification efficiency of the fractionation flask but also can continuously filter a large amount of argon, greatly improving the filtration efficiency.

[0031] As a further embodiment provided by the present utility model, a nozzle 4 is arranged on the condensation pipe 3 in an array along the pipe wall of the condensation pipe 3.

[0032] Furthermore, a recovery tank 8 is fixedly installed at the bottom end of the condensation tank 1, and the recovery tank 8 is communicated with the condensation tank 1.

[0033] Specifically, the cooling liquid in the condensation pipe 3 is sprayed on the inlet pipe 5 through the nozzle 4, causing the temperature of the inlet pipe 5 to quickly drop to -100°C. The recovery tank 8 recovers the sprayed cooling liquid to avoid waste of the cooling liquid.

[0034] As still another embodiment provided by the present utility model, a flow guide plate 6 is fixedly installed in the inlet pipe 5, and a collection plate 7 is movably installed in the inlet pipe 5. One end of the collection plate 7 abuts against the flow guide plate 6.

[0035] Specifically, when the impurities in the inlet pipe 5 with a condensation point lower than -100°C condense into a liquid, the liquid is guided to the collection plate 7 through the flow guide plate 6 to prevent the liquid from accumulating on the inner wall of the inlet pipe 5 and corroding the inner wall of the inlet pipe 5.

[0036] As yet another embodiment provided by the present utility model, a heating chamber 12 is fixedly installed at the bottom end of the purification tank 2, a heating sheet 13 is fixedly installed in the heating chamber 12, and a glass plate 14 is fixedly installed at the top end of the heating chamber 12.

[0037] Specifically, the heating sheet 13 installed in the heating chamber 12 heats the purification tank 2, so that the temperature in the purification tank 2 is higher than 0°C. Thus, when the argon at -100°C enters the purification tank 2, it can quickly heat up. The glass plate 14 isolates and protects the heating sheet 13 to prevent the heating sheet 13 from being damaged.

[0038] As yet another embodiment further provided by the present utility model, an air outlet pipe 9 is fixedly installed at the top end of the purification box 2.

[0039] Furthermore, an air extraction fan 10 is fixedly installed at the bottom end of the air outlet pipe 9, and an argon filter membrane 15 is fixedly installed at the air outlet of the air extraction fan 10.

[0040] Specifically, the air extraction fan 10 sucks the argon in the purification box 2, so that the argon in the purification box 2 passes through the getter layer 11 and flows into the air extraction fan 10. When the argon flows out from the air outlet of the air extraction fan 10, the argon filter membrane 15 installed on the air extraction fan 10 performs a third filtration on the argon, making the purity of the argon higher. When the argon passes through the argon filter membrane 15, it can be collected into the encapsulation bottle through the air outlet pipe 9.

[0041] Working principle: When a worker connects the encapsulation bottle filled with argon to the inlet pipe 5, the argon flows along the inlet pipe 5. During the flowing process, the argon enters the condensation box 1. By continuously pouring a refrigerant into the condensing pipe 3, the condensing pipe 3 reduces the temperature in the condensation box 1. Since the condensing pipe 3 is arranged around the side wall of the inlet pipe 5, the condensing pipe 3 quickly cools down the inlet pipe 5, and the refrigerant is sprayed on the outer wall of the inlet pipe 5 through the spray head, so that the temperature of the argon in the inlet pipe 5 quickly drops to -100°C. When the argon drops to -100°C, the impurities in the argon with a condensation point lower than -100°C will quickly condense into a liquid and separate from the argon, completing the first purification of the argon. The condensed liquid flows into the collection plate 7 through the diversion plate 6 for collection. When the argon at -100°C passes through the inlet pipe 5 and enters the purification box 2, the temperature in the purification box 2 is heated above 0°C by the heating sheet 13, so that the argon at -100°C quickly warms up, and thus the argon quickly expands and flows towards the air outlet pipe 9 of the purification box 2. At the same time, the air extraction fan 10 sucks the argon in the purification box 2, making the argon flow quickly towards the air outlet pipe 9. During the flowing process of the argon, it passes through the getter layer 11, and the getter performs a secondary filtration on the argon, so that the trace impurities in the argon are absorbed by the getter. When the argon passes through the getter layer 11, the extraction fan blows the argon after the secondary filtration into the argon filter membrane 15 for a third filtration, making the purity of the argon higher. When the argon passes through the argon filter membrane 15, it can be collected into the encapsulation bottle through the air outlet pipe 9.

[0042] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
