Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-3This utility model provides a technical solution: a gas canister purification device, including a cleaning chamber 2 for dust removal from air and two purification tanks 1 arranged side by side. A sealing cap 3 is detachably connected to the top opening of each purification tank 1, and a purification mechanism 7 is fixedly connected to the bottom of the sealing cap 3. The purification mechanism 7 includes a first purification module 71, a second purification module 72, and a third purification module 73 arranged sequentially from bottom to top. The first purification module 71 is used to initially adsorb moisture in the air, the second purification module 72 is used to remove moisture and carbon dioxide from the air, and the third purification module 73 is used to remove nitrogen from the air. By setting up the cleaning chamber 2, the three-way valve 6, and the air inlet pipe 4, the two purification tanks 1 can be purified separately, ensuring that the device continues to purify gas while a single purification tank 1 is being cleaned.

[0024] The cleaning chamber 2 is equipped with water for dust removal from the air. The cleaning chamber 2 is equipped with a gas collection hood 5, and the gas collection hood 5 is equipped with a three-way valve 6. The purification tank 1 is equipped with an air inlet pipe 4 for conveying gas. There are two air inlet pipes 4, which correspond to two purification tanks 1, and both air inlet pipes 4 are connected to the three-way valve 6.

[0025] A first connecting rod 9 is fixedly connected to the purification mechanism 7. A sealing block 8 is provided below the sealing cover 3 to seal the gap between the sealing cover 3 and the purification tank 1. The sealing block 8 is provided with rubber. The sealing block 8 is fixedly connected to the purification mechanism 7 through the first connecting rod 9.

[0026] The first purification module 71 and the second purification module 72 are detachably connected, and the second purification module 72 and the third purification module 73 are detachably connected. The first purification module 71, the second purification module 72 and the third purification module 73 are all provided with a ventilation plate 74 for supporting the adsorbent. By setting the first purification module 71, the second purification module 72 and the third purification module 73, it is convenient to place various adsorbents for removing excess gas.

[0027] The first purification module 71 is filled with a desiccant 76 for initial moisture absorption, the second purification module 72 is filled with sodium peroxide particles 77 for removing moisture and carbon dioxide, and the third purification module 73 is filled with zeolite molecular sieves 78 for removing nitrogen.

[0028] The purification tank 1 is provided with a connecting block 10 and a second connecting rod 11 inside. The connecting block 10 is threadedly connected to the purification tank 1. One end of the second connecting rod 11 is fixedly connected to the connecting block 10, and the other end of the second connecting rod 11 is fixedly connected to the purification mechanism 7. By setting the second connecting rod 11 and the connecting block 10, it is easier to make the connection between the purification mechanism 7 and the purification tank 1 tighter.

[0029] The first purification module 71 is provided with a positioning block 75, and the inner wall of the purification tank 1 is provided with a movable groove 12 that is adapted to the positioning block 75. The movable groove 12 includes an insertion groove for inserting the positioning block 75 and an annular groove for rotating the positioning block 75. By setting the positioning block 75 and the movable groove 12, it is convenient to quickly position and install the purification mechanism 7.

[0030] The purification tank 1 is equipped with a rubber ring 13 for sealing the movable groove 12. The purification tank 1 is equipped with an output pipe 14 for passing purified oxygen out, and a valve is installed on the output pipe 14. The sealing cover 3 is equipped with a locking buckle 15 for installation with the purification tank 1, which facilitates quick disassembly of the purification mechanism 7 and allows personnel to replace the adsorbent that removes excess gas, thus avoiding a decrease in purification efficiency caused by prolonged adsorption of the adsorbent. Therefore, this gas canister purification equipment has the effect of improving oxygen purification efficiency.

[0031] Working principle: First, air is introduced into the water in the cleaning chamber 2. The water removes impurities and particles from the air. Then, the air leaves the water and passes through the gas collection hood 5, the three-way valve 6, and the air inlet pipe 4 into the purification tank 1. The gas then passes through the first purification module 71, the second purification module 72, and the third purification module 73 to remove moisture, carbon dioxide, and nitrogen from the air, producing clean oxygen. The oxygen is then discharged from the output pipe 14 for bottling.

[0032] After prolonged operation, the adsorbent adsorbs excessive impurities, leading to a decrease in adsorption capacity and necessitating replacement. There are two purification tanks 1. First, close the valve on the corresponding air inlet pipe 4 of one purification tank 1 to stop its operation. The other purification tank 1 can still operate. First, open the latch 15 on the stopped purification tank 1, then rotate the sealing cover 3. This causes the purification mechanism 7 and the connecting block 10, which are fixedly connected to the sealing cover 3, to rotate. The connecting block 10 is threadedly connected to the purification tank 1. After rotation, the connecting block 10 can be separated from the purification tank 1. Then, personnel can lift the sealing cover 3, thereby lifting the purification mechanism 7 and separating the purification machine from the purification tank 1. Personnel can then disassemble the first purification module 71 and the second purification module 72, and disassemble the second purification module 72 and the third purification module 73 to update the adsorbent. Replacing the adsorbent ensures the gas purification rate, thus improving the oxygen purification efficiency of this gas canister purification equipment.

[0033] The mechanisms, components, and parts in this utility model that are not specifically described are all existing structures that already exist in the prior art and can be purchased directly from the market.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
