Description

A multi-stage purity purification device and purification method for argon preparation

Technical Field

The present invention relates to the technical field of argon preparation, and in particular to a multi-stage purity purification device and a purification method for argon preparation.

Background technique

Argon is a rare gas used as a shielding gas for arc welding (cutting) of stainless steel, magnesium, aluminum, and other alloys. It is also used in the smelting of steel, aluminum, titanium, and zirconium. Argon emits a purple glow when discharged. It is also used in lighting technology and filling fluorescent lamps, photoelectric tubes, lighting tubes, etc. When preparing argon, the crude argon needs to be purified to improve the preparation quality.

The current argon preparation and purification equipment has two sets of processing boxes on the reaction tank. The regulating valve of the left shunt pipe is opened, and the argon enters the left processing box to absorb the impurities in the argon. When the getter layer in the left processing box is saturated, the left regulating valve is closed and the right regulating valve is opened. At this time, the argon will enter the right processing box for purification operation.

However, since two sets of processing boxes are provided, not only will the manufacturing cost of the equipment be increased, but also when the processing boxes are switched for argon purification, some argon will remain in the original processing boxes, resulting in a waste of argon. Therefore, there is room for improvement.

Step 2: The reacted argon gas enters the heating box 7 from the blocking tube 6, is heated and dried by the heating rod 78 in the heating box 7, and then passes into the processing box 9 through the connecting tube 8;

Step three: the electric heating network 25 in the treatment box 9 is powered on to dry the argon gas again. The dried argon gas is treated with other impurities contained in the argon gas by the getter layer in the getter box 12, and then discharged from the exhaust pipe 11, thus achieving the purification of the argon gas.

The implementation principle of a multi-stage purity purification device and purification method for argon preparation in an embodiment of the present invention is as follows: first, a proper amount of reaction liquid is introduced into the reaction tank 1 through the liquid inlet pipe 2, and the crude argon gas to be purified is introduced into the reaction liquid in the reaction tank 1 through the delivery pump 5 for reaction, and the third cylinder 79 and the liquid pump 66 are started, and the third cylinder 79 drives the lifting ring 68 and the nozzle 70 to move up and down as a whole in the reaction tank 1, and the liquid pump 66 draws the reaction liquid in the reaction tank 1 into the lifting ring 68 and sprays it out from the nozzle 70, so that the reaction between the argon gas and the reaction liquid is completely eliminated, thereby improving the quality of argon purification, and when the lifting ring 68 moves, it drives the lifting rod 71 to move up and push the chassis 72, and cooperates with the reset ability of the fourth spring 77 to make the plug head 74 moves up and down in the blocking tube 6 to intermittently open the blocking tube 6 to extend the purification time of the argon in the reaction tank 1. Then, the argon purified by the reaction liquid in the reaction tank 1 enters the heating box 7 and is heated and dried by the heating rod 78. Then, it is passed into the processing box 9 through the connecting tube 8 and dried again by the electric heating network 25 in the processing box 9. Then, the getter layer of the getter box 12 absorbs other impurities in the argon to further purify the argon. In addition, the airflow at one end of the connecting tube 8 is used to drive the rotating blade 35 and the third rotating rod 36 to rotate as a whole. The third rotating rod 36 drives the top end of the second rotating rod to slide back and forth in the driving frame 34, drives the U-shaped bar 30 to move back and forth, and drives the guide plate 28 to swing back and forth through the first gear 29 to evenly distribute the argon. The argon is guided to the getter layer to absorb impurities. After the argon is purified, it can be discharged from the exhaust pipe 11. After the getter layer in the upper getter box 12 in the processing box 9 is saturated, the first cylinder 19 is started to drive the two ends of the through rod 20 to slide in the first guide groove 15 and the second guide groove 16 respectively. The through rod 20 first pushes the getter box 12 for replacing the getter layer below to be inserted into the processing box 9 to purify the argon. As the through rod 20 continues to move upward, the upper getter box 12 is pushed out of the processing box 9 to replace the saturated getter layer. When the reaction product in the corresponding reaction tank 1 needs to be cleaned, the second cylinder 37 is started to drive the filter plate 38 to move upward, and the filter plate 38 filters out the reaction product, and The push bar 46 pushes the horizontal bar 49 to push the baffle plate 47 upward in the groove 48, opening the discharge port 39, so that the impurities filtered out of the filter plate 38 roll into the discharge port 39 and are collected by the collecting frame 41. As the horizontal bar 49 moves upward, the elastic force of the second spring 55 drives the U-shaped frame 60 to slide against the side of the guide bar 61 to drive the L-shaped bar 59 to move back and forth, and the rotating frame 57 is driven to rotate up and down through the second gear 58, thereby driving the knocking block 64 to knock on the filter plate 38. The vibration generated during the knocking process is used to better collect the reaction products filtered out of the filter plate 38 into the collecting frame 41 for centralized treatment. When the purification work is completed, the drain pipe 3 is opened to discharge the reaction liquid in the reaction tank 1.

The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
