Description

Technical Field

[0001] The utility model relates to the technical field of air intake modules and hydrogen fuel cell systems, and in particular to an air intake module capable of filtering sulfides. Background Art

[0002] A hydrogen fuel cell is a device that generates electricity by reacting hydrogen and oxygen under the action of a catalyst. A battery air intake module that can filter sulfides is an air intake treatment device for a battery system that is designed to remove sulfide compounds from the air to protect the battery system from contamination and damage by sulfides.

[0003] When the existing air intake module is in use, it generally adopts an air intake pipe design, which results in the inability to continue filtering when the filter element is replaced, and the overall filtering efficiency is low. In addition, when the filter element is replaced in the existing air intake module, it is necessary to use tools to remove the filter element inside the pipe. The whole process is relatively troublesome. Therefore, it is necessary to provide an air intake module that can filter sulfides to solve the above technical problems. Utility Model Content

The arrangement of the slide groove enables the slider to slide inside the slide groove when the filter element is replaced, thereby providing convenience for the staff in replacing the filter element.

[0008] Preferably, the air intake pipe adopts a three-way structure, and both ends of the air intake pipe are connected to the first connecting pipe by screws and nuts. The first connecting pipe and the air intake pipe are connected by screws and nuts, which increases the stability of the entire device and avoids looseness between parts.

[0028] A first connecting block 11 and a second connecting block 14 are placed in the middle position of the inner side of the two groups of filter tubes 1, and the upper and lower ends of the first connecting block 11 and the second connecting block 14 are fixedly connected with a connecting rod 12, and a rotating block 13 is fixedly connected to the connecting rod 12. A plurality of evenly distributed rotating handles 15 are fixedly connected to the outer wall of the second connecting block 14. The outer sides of the first connecting block 11 and the second connecting block 14 are hinged with a first connecting rod 16, and a movable rod 17 is hinged on the first connecting rod 16, and a clamping block 18 is fixedly connected to the movable rod 17. A protective cover 19 is fixedly connected to the outer wall of the filter tube 1, and the movable rod 17 is slidably installed inside the protective cover 19. A second connecting rod 20 is hinged between the first connecting block 11 and the second connecting block 14.

[0029] Specifically, a plurality of evenly distributed slide grooves are provided on the inner wall of the filter tube 1, and each slider 9 is slidably installed inside the slide groove. The setting of the slide groove enables the slider 9 to slide inside the slide groove when the filter element 7 is replaced, thereby providing convenience for the staff in replacing the filter element 7.

[0030] Specifically, the air intake pipe 4 adopts a three-way structure, and both ends of the air intake pipe 4 are connected to the first connecting pipe 3 by screws and nuts. The first connecting pipe 3 and the air intake pipe 4 are connected by screws and nuts, which increases the stability of the entire device and avoids looseness between parts.

[0031] Specifically, the air outlet pipe 6 adopts a three-way structure, and both ends of the air outlet pipe 6 are connected to the second connecting pipe 5 by screws and nuts. The second connecting pipe 5 and the air outlet pipe 6 are connected by screws and nuts, which increases the stability of the entire device and avoids looseness between parts.

[0032] Specifically, the rotating block 13 located at the upper end of the connecting rod 12 is rotatably installed between the first connecting pipe 3 and the air inlet pipe 4, and the rotating block 13 located at the lower end of the connecting rod 12 is rotatably installed between the second connecting pipe 5 and the air outlet pipe 6. After rotating the rotating block 13, the filtering path of the air can be changed, and further, when the filter element 7 is replaced, the entire filtering device can still perform normal filtering work, thereby effectively improving the filtering efficiency of the air intake module.

[0035] Working principle: When starting to use an air intake module that can filter sulfides, first connect the air outlet pipe 6 to the corresponding equipment, and then the air intake module can start normal filtering work. When the filter element 7 needs to be replaced during the use period, the initial state: the pipe connection on one side is sealed by the rotating block 13, and the pipe connection on the other side is in a connected state. By rotating the rotating handle 15, the second connecting block 14 is driven to rotate. Under the action of the connecting rod 12 and the second connecting rod 20, the four groups of rotating blocks 13 all start to rotate. At this time, the connected or closed state of the two pipe connections changes, and the air filtering path also changes. At the same time, When the first connecting block 11 and the second connecting block 14 start to rotate, the first connecting rod 16 will be driven to move, and then the first connecting rod 16 will drive the movable rod 17 and the clamping block 18 to slide inside the protective cover 19, so that the clamping block 18 on one side just clamps the fixed block 8 on the outer wall of the filter element 7, and the clamping block 18 on the other side will leave the upper end of the other fixed block 8, and the filter element 7 at the other place will pop out of the filter tube 1 under the action of the spring 10, and then the staff can open the filter cover 2 and directly take out the filter element 7 by the handle for replacement. This is the entire working process of an intake module that can filter sulfides.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
