Description

Technical Field

[0001] This utility model relates to the technical field of helium-argon mixed gas production equipment, and in particular to a fully automatic deoxygenation and drying equipment for helium-argon mixed gas. Background Technology

[0002] Helium-argon mixtures combine the properties of both helium and argon, possessing the advantages of both. Helium has high thermal conductivity, providing more heat input and helping to improve the fluidity of the molten pool; while argon has stable arc and protective properties. Helium-argon mixture deoxygenation refers to the process of removing oxygen from the helium-argon mixture. This process is crucial in industrial production and scientific research experiments because the presence of oxygen can affect the performance and stability of the mixture. Physical deoxygenation methods typically use adsorbents such as molecular sieves, zeolites, and activated carbon to selectively adsorb oxygen; while the drying process usually involves passing the gas through a desiccant to dry it.

[0003] The prior art Chinese utility model patent with application number CN201922453979.9 relates to a gas drying device and a differential calorimeter scanner using the gas drying device, including an inlet pipe, a drying pipe, an outlet pipe, a cap, and a water-absorbing material, which can dry the gas.

[0004] However, in actual use, the filter elements of the aforementioned devices often need to be replaced regularly, and the equipment can only continue to operate after the filter elements are replaced. The filter element replacement process usually consumes a lot of time and affects production efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a fully automatic deoxygenation and drying equipment for helium-argon mixed gas. The equipment draws in gas through a driving device, pressurizes it, and sends it to a deoxygenation device. A transverse moving device quickly connects or disconnects the deoxygenation device from the driving device, thereby quickly replacing the deoxygenation device and reducing the time required for filter replacement. The deoxygenation device separates oxygen and water in the gas, improving the practicality of the equipment.

[0006] This utility model discloses a fully automatic deoxygenation and drying device for a helium-argon mixture; it includes a drive unit, a transverse movement unit, and a deoxygenation unit. The transverse movement unit is mounted on the drive unit, and the deoxygenation unit is mounted on the transverse movement unit. The drive unit draws in the gas, pressurizes it, and sends it to the deoxygenation unit. The transverse movement unit quickly connects or disconnects the deoxygenation unit from the drive unit, thereby enabling rapid replacement of the deoxygenation unit and reducing the time required for filter replacement. The deoxygenation unit separates oxygen and water from the gas, improving the practicality of the device.

[0007] Preferably, the driving device includes a base plate, a pressurizing chamber, a first electric cylinder, an inlet valve, an outlet valve, and a piston. The pressurizing chamber is mounted on the rear of the upper end face of the base plate via support legs. The first electric cylinder is mounted on the upper end face of the pressurizing chamber. The moving end of the first electric cylinder extends through the upper end face of the pressurizing chamber into the interior of the pressurizing chamber and connects with the piston. An inlet and an outlet are respectively provided at the front and rear of the lower part of the pressurizing chamber, and an inlet valve and an outlet valve are respectively installed on the inlet and outlet. The inlet and outlet valves control the opening and closing of the inlet and outlet of the pressurizing chamber, and in conjunction with the extension and retraction of the first electric cylinder, drive the piston to move up and down in the pressurizing chamber, drawing external gas into the interior of the pressurizing chamber, pressurizing it, and sending the gas out to the deoxygenation device. When it is necessary to use a transverse movement device to disconnect the deoxygenation device from the pressurizing chamber, the inlet is closed and the piston is raised to draw the residual gas in the deoxygenation device back into the pressurizing chamber, reducing gas overflow and improving the practicality of the device.

[0008] Preferably, the device also includes a liquid storage tank and a solenoid valve. The bottom of the pressurization chamber is connected to the liquid storage tank, and the solenoid valve is installed on the lower end face of the liquid storage tank. The liquid storage tank collects the liquid generated during the pressurization process of the gas in the pressurization chamber, and the solenoid valve periodically discharges the liquid, reducing the impact of the liquid on the effective working space in the pressurization chamber and improving the practicality of the device.

[0009] Preferably, the transverse movement device includes a support platform, linear guide rails, a transverse movement platform, a lead screw, and a first reduction motor. A support platform is mounted on the upper front of the base plate. A set of linear guide rails is positioned on the left and right sides of the upper surface of the support platform. The lower part of the transverse movement platform is connected to the two sets of linear guide rails. A lead screw is mounted on the upper surface of the support platform via a bracket, positioned between the two sets of linear guide rails, and connected to the transverse movement platform via a nut. A first reduction motor is mounted on the front front of the bracket, and its output end is connected to the lead screw. Activating the first reduction motor transmits power to the lead screw, causing it to rotate. This, in turn, coordinates with the nut on the transverse movement platform to move the platform back and forth, thereby connecting or disconnecting the deaerator from the outlet of the pressurization chamber. The two sets of linear guide rails provide auxiliary support to the transverse movement platform and reduce its own vibration amplitude during transverse movement, improving the stability and practicality of the device.

[0010] Preferably, the deoxygenation device includes a rotating platform, a rotating shaft, a second geared motor, a deoxygenation chamber, a composite filter element, a sealing connector, and a sealing ring. The rotating shaft is mounted on the upper surface of the transverse platform via a bracket. The rotating platform is located in the middle of the rotating shaft. Two sets of deoxygenation chambers are symmetrically installed on the left and right sides of the rotating platform. The second geared motor is mounted on the front end of the bracket on the transverse platform, and its output end is connected to the rotating shaft. A set of sealing connectors is provided on the front and rear end faces of each deoxygenation chamber. An annular groove is provided on the inner surface of the sealing connector, and a sealing ring is placed in the annular groove. A composite filter element is placed inside the deoxygenation chamber. When the transverse device moves the rear of the deoxygenation chamber to the outlet of the pressurization chamber, connecting the outlet of the pressurization chamber with the rear sealing connector, the driving device sends gas into the deoxygenation chamber. The composite filter element adsorbs oxygen and water from the gas. The front sealing connector is connected to an external hose to send the gas out, and the sealing ring reduces gas pressure. When the gas overflows and the composite filter needs to be replaced, disconnect the hose connected to the front sealing connector and close the air inlet of the pressurized chamber. Simultaneously, control the piston to rise and draw the gas in the composite filter back into the pressurized chamber. Then close the outlet valve. Afterward, the lateral movement device moves the lateral movement platform forward to separate the rear sealing connector from the air outlet of the pressurized chamber. Then, turn on the second reduction motor to transmit power to the rotating shaft and rotate it to the right. Then, control the lateral movement device to push the lateral movement platform backward until the rear sealing connector of the other deoxygenation chamber connects to the air outlet of the pressurized chamber. Connect the front sealing connector of the other deoxygenation chamber to the external hose, so that the equipment can quickly complete the replacement of the composite filter. Afterward, open the sealing connector on the replaced composite filter and replace the old composite filter. This shortens the maintenance time required for the equipment and improves the overall production efficiency and practicality of the equipment.

[0011] Preferably, the device also includes a second electric cylinder, a limiting plate, and a limiting frame. The second electric cylinder is installed in the middle of the upper end face of the transverse platform, and a limiting plate is installed on the moving end of the second electric cylinder. A set of limiting frames is respectively provided on the upper and lower end faces of the rotating platform. After the positions of the two sets of deoxygenation chambers are interchanged, the second electric cylinder is controlled to extend so that the limiting plate rises and presses against the limiting frame, thereby limiting the horizontal position of the deoxygenation chamber, ensuring the connection stability between the deoxygenation chamber and the air outlet of the pressurization chamber, and improving the practicality of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: after the gas is drawn in by the driving device, it is pressurized and sent to the deoxygenation device. The deoxygenation device is quickly connected or disconnected from the driving device by the transverse moving device, thereby quickly replacing the deoxygenation device and reducing the time required for replacing the filter element. The deoxygenation device separates oxygen and water in the gas, improving the practicality of the device. Attached Figure Description

When the composite filter element 18 needs replacement, the hose connected to the front sealing connector 19 is disconnected, and the inlet of the pressurization chamber 2 is closed. Simultaneously, the piston 6 rises to draw the gas from the composite filter element 18 back into the pressurization chamber 2.
