Description

Technical Field

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

[0002] At industrial gas filling stations without cryogenic air separation equipment on site, high-purity gases such as oxygen, nitrogen, and argon are transported in liquid cans. The liquid gas is canned in a tank truck storage tank. Since the tank truck storage tank is at room temperature at the beginning of canning, the filled liquid gas will be quickly vaporized. At the same time, the tank truck tank body is quickly cooled until the liquid and gas reach equilibrium temperature and the tank is filled. This part of the gas needs to be released. If these vaporized gases that need to be released can be recycled, it will greatly save production costs. Since the market price of argon is several times that of oxygen and nitrogen, this part of the leaked gas is usually recovered in the actual application of argon. However, at present, when the leaked argon gas is filled into the recovery gas tank, due to the lack of a purification structure, the tank metal or particulate impurities retained in the leaked argon gas will directly enter the recovery gas tank, resulting in the tank metal or particulate impurities remaining in the recovery gas tank and being inconvenient to remove. After repeated use, it will directly affect the release and storage performance of the recovery gas tank.

[0003] Patent application number CN202120642297.7 A argon gas recovery and purification device includes a purification tube body, the purification tube body is a tube body structure with two ends open, and the two ends of the purification tube body are coaxially fixed with a quick connector male and a quick connector female respectively; a radially extending annular flange is coaxially fixed to one end of the inner wall of the purification tube body, and a threaded portion is provided at the other end of the interior of the purification tube body. The beneficial effect is that the utility model disconnects and installs a quick connector between the pipelines for conveying the discharged argon gas to the recovery gas tank, and then quickly installs the quick connector male and the quick connector female at both ends of the purification tube body by respectively matching and combining with the quick connector at the disconnection point of the pipeline, and then purifies the discharged argon gas by passing through the purification tube body and being adsorbed and filtered by the internal purification component, thereby avoiding the tank metal or particulate impurities retained in the discharged argon gas from directly entering the recovery gas tank, which is conducive to ensuring the stable release and storage performance of the recovery gas tank.

[0004] This structure connects a tube body between the recovery point and the recovery tank and purifies the argon gas through a built-in purification component. However, when the purification particles in this structure need to be replaced, the tube body and the internal structure need to be disassembled as a whole, resulting in too many operating steps affecting the recovery efficiency. At the same time, the purification particles remain stable and the argon contact area is small, resulting in poor purification effect. Therefore, professionals in this field provide an argon recovery and purification device to solve the above-mentioned problems. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] See also Figures 1 to 4In the utility model, an argon gas recovery and purification device comprises a recovery and purification pipe 1, both ends of the recovery and purification pipe 1 are connected with flanges 2, a limited seat 3 is fixedly connected to the inner wall of the recovery and purification pipe 1, a mounting seat 4 is rotatably connected inside the limited seat 3, a mounting plate 5 is arranged on the right side of the mounting seat 4, a uniformly distributed connecting shaft 6 is fixedly connected to the left side of the mounting plate 5, the left end of the connecting shaft 6 is connected to the mounting seat 4, a filter plate 7 is connected to the mounting seat 4 and the mounting plate 5, and an adding groove 8 and a filter plate 7 are respectively provided on the top and bottom of the recovery and purification pipe 1. The discharge groove 9, the addition groove 8 and the discharge groove 9 are all located between the mounting seat 4 and the mounting plate 5, and the mounting seat 4 and the mounting plate 5 are filled with purification particles 10. A limit ring 11 is movably installed on the inner wall of the recovery purification tube 1, and the limit ring 11 is located on the right side of the mounting plate 5. The outer side of the recovery purification tube 1 is slidably connected with a sealing tube 12, and the addition groove 8 and the discharge groove 9 are both located inside the sealing tube 12. The outer side of the recovery purification tube 1 is fixedly connected with a positioning plate 13, and the positioning plate 13 is connected to the sealing tube 12, wherein the bottom protruding part of the sealing tube 12;

[0023] The left side of the limiting ring 11 is rotatably connected with a synchronization ring 15, and the left side of the synchronization ring 15 is in contact with the mounting plate 5;

[0024] An internal thread is provided on the inner wall of the recovery and purification pipe 1, and an external thread is provided on the outer side of the limiting ring 11, and the internal thread is adapted to the external thread;

[0025] The sides of the mounting seat 4 and the inner side of the limiting seat 3 are both in an inclined state.

[0026] The recovery purification pipe 1 is assembled, and the mounting seat 4 and the mounting plate 5 are formed as a whole through multiple sets of connecting shafts 6. The user inserts the mounting seat 4 from the left side of the recovery purification pipe 1 so that the inner wall of the mounting seat 4 fits with the inner wall of the limiting seat 3. Then the user screws the limiting ring 11 into the interior of the recovery purification pipe 1. Under the cooperation of the internal thread and the external thread, the synchronous ring 15 on the left side of the limiting ring 11 contacts the right side of the mounting plate 5, which restricts the mounting plate 5, so that the mounting seat 4 and the mounting plate 5 remain stable and can also rotate. Then the user connects the two ends of the recovery purification pipe 1 to the recovery point and the recovery tank respectively through the flange 2. Then the user fills the purification particles 10 between the mounting seat 4 and the mounting plate 5 through the adding groove 8 on the top. At this time, the discharge groove 9 at the bottom is blocked by the protruding part of the sealing tube 12 to form a seal, and then the purification particles 10 are added under the continuous addition of the user. , then the user moves the sealing tube 12 to the right, so that the sealing tube 12 moves to the peak value and contacts the positioning plate 13 and is locked, and the sealing of the recovery purification tube 1 is completed. Then the argon enters through the left side, and the mounting seat 4 can be rotated under the action of the airflow. The argon penetrates the filter plate 7, so that large particles of impurities cannot penetrate. Then the argon enters the inside of the mounting seat 4 and penetrates the right mounting plate 5 to enter the inside of the recovery tank. The purification particles 10 will purify the argon. When the purification particles 10 need to be replaced and cleaned, the user separates the sealing tube 12 from the positioning plate 13 and moves the sealing tube 12 to the left until the discharge slot 9 is exposed. The purification particles 10 are discharged through the discharge slot 9, and the rotation of the inclined mounting seat 4 and the multiple groups of connecting shafts 6 will accelerate the discharge speed. Then the sealing tube 12 is moved to the right part so that the bottom part of the sealing tube 12 blocks the discharge slot 9, and the purification particles 10 can be added again.

[0027] In the utility model, by setting the addition groove 8 and the discharge groove 9, it is possible to quickly replace and add the purification particles 10 for purifying argon gas without removing the recovery purification tube 1, thereby reducing the operation steps and the required time, and improving the recovery efficiency of argon gas. At the same time, the mounting seat 4 and the mounting plate 5 loaded with the purification particles 10 can be rotated, thereby increasing the contact area between the argon gas and the purification particles 10 and improving the purification effect.

[0028] See also Figure 2 and 3 , wherein: a rubber ring 14 is fixedly connected to the outer side of the recovery and purification tube 1, a fitting groove is opened on the inner wall of the sealing tube 12, and the rubber ring 14 is located inside the fitting groove.

[0029] In the utility model, when the user moves the sealing tube 12, the rubber ring 14 will have a certain obstructive effect, but will not affect the normal movement of the sealing tube 12. When the sealing tube 12 is connected, a certain positioning effect can be achieved through the cooperation between the fitting groove and the rubber ring 14, which is convenient for the subsequent connection with the positioning plate 13.

[0030] See also Figure 2 and 4 , wherein: an extension plate 16 is fixedly connected to the inner wall of the limiting ring 11, and the extension plate 16 is provided with evenly distributed anti-slip grooves.

[0031] In the utility model, when a user needs to install the limit ring 11, the extension plate 16 can provide a good fulcrum, and the anti-slip pattern can prevent the user from slipping.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
