Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen circulation purification, in particular to a hydrogen circulation anti-blocking purification device. Background Art

[0002] Hydrogen purification is a general term for methods of removing impurities from hydrogen using physical or chemical methods. It is the purification of substances or impurities learned in chemistry class. It can be done by physical or chemical methods. In the process of stainless steel production, hydrogen is needed, so a hydrogen circulation purification device is indispensable.

[0003] After searching the hydrogen circulation purification device for stainless steel production disclosed in Chinese patent announcement number CN215538903U, when the staff needs to replace the filter structure, they directly pull the pull-out block, and the pull-out block drives the pressure plate to move away from the shell, the pressure in the third connecting groove changes, and with the cooperation of the second connecting groove, the two fixed blocks move away from each other. When the fixed blocks and the shell are out of the snap-fit ​​state, the staff can remove the filter structure for replacement. When the staff needs to install a new filter structure, they directly align the shell with the snap-fit ​​plate and press the shell. After the two fixed blocks are squeezed, they move away from each other. When the shell moves to the appropriate position, under the action of two springs, the two fixed blocks move towards each other. When the fixed blocks are snapped into the inside of the shell, the installation of the filter structure is completed. The operation is simple and quick, which reduces the difficulty of operation for the staff while ensuring the purification effect of the purification device on hydrogen and improving the applicability of the purification device.

[0004] However, the above patent has certain deficiencies in actual use. Although the purification effect of the purification device on hydrogen can be guaranteed and the applicability of the purification device can be improved, no anti-clogging structure is provided for hydrogen, which affects the purification effect after long-term filtration. At the same time, when the filter structure is replaced, the entire filter structure is replaced, which causes a certain waste of part of the filter.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
