Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1 to 5, the present invention provides a technical solution:

example (b):

as shown in fig. 1 to 5, a humidifier with an adjustable partition plate for a hydrogen fuel cell includes a housing 1, a partition plate 2, a fixed tube 3 and a fiber membrane module 4, wherein two ends of the housing 1 are respectively provided with an end cover 5, one of the end covers 5 is provided with a dry air inlet 6, the other end cover is provided with a dry air outlet 7, the housing 1 is provided with a wet air inlet 8 and a wet air outlet 9, the fiber membrane module 4 is arranged in the fixed tube 3, the fixed tube 3 is arranged in the housing 1 through the partition plate 2, and two ends of the fixed tube 3 are respectively communicated with the dry air inlet 6 and the dry air outlet 7; the partition board 2 is in sliding connection with the shell 1, an adjusting assembly used for adjusting the partition board 2 is arranged in the shell 1, the adjusting assembly comprises a lead screw 10 and a sliding block 11 matched with the lead screw 10, a mounting groove is formed in the bottom of the partition board 2, the sliding block 11 is connected with the partition board 2 through the mounting groove, the lead screw 10 is connected with the bottom of the shell 1 through a bearing seat, a driven bevel gear 12 is arranged on the lead screw 10, a driving shaft 13 is arranged at the inner bottom of the shell 1, one end of the driving shaft 13 extends out of the shell 1, and a driving bevel gear 14 meshed with the driven bevel gear 12 is arranged on the driving shaft 13.

The end of the drive shaft 13 extending out of the housing 1 is provided with a handle 15. The specific working principle of the humidifier is common knowledge in the art, and is not described in detail herein.

The sliding block 11 is fixedly connected with the partition plate 2, and the driving shaft 13 is rotatably sealed with the housing 1 (one of the rotary seals is a common knowledge in the art, and is not described herein again). The partition plate 2 and the shell 1, and the partition plate 2 and the fixed pipe 3 are all sealed, and the specific sealing manner may be, but is not limited to, providing rubber sealing layers on the circumferential direction of the partition plate 2 and the hole walls of the holes on the partition plate 2.

In fig. 1, G1 and G2 respectively represent a dry gas inlet and a dry gas outlet; s1 and S2 respectively indicate the humid air intake and the humid air outtake; a denotes a cavity between the wet air inlet and the partition, and b denotes a cavity between the wet air outlet and the partition.

The working principle is as follows: the driving shaft 13 is rotated, the driving bevel gear 14 on the driving shaft 13 drives the driven bevel gear 12 to rotate, the driven bevel gear 12 drives the screw rod 10 to synchronously rotate, the screw rod 10 drives the sliding block 11 to do linear motion along the screw rod 10 when rotating, and the sliding block 11 drives the partition plate 2 to synchronously move. When it is desired to increase the rate of entry of humid air, the partition 2 is moved towards the humid air inlet 8. Like this the cavity a between humid air inlet 8 and the baffle 2 is small, when humid air gets into cavity a by humid air inlet 8, can spread to whole cavity a fast, and then gets into fixed pipe 3 by the inlet port on the fixed pipe 3, can reduce the content of humid air in the cavity a simultaneously, guarantees that humid air gets into fixed pipe 3 as much as possible. Similarly, when the partition board 2 moves towards the wet air outlet 9, the volume of the cavity a is increased, the volume of the cavity b is decreased, and wet air can be rapidly discharged from the wet air outlet 9 when coming out from the fixing pipe 3.

The partition plate 2 of the humidifier can be adjusted according to requirements, so that the volume of the cavity in the shell 1 is adjusted, and the humidifying efficiency is guaranteed.

Further, as shown in fig. 1, the inner top and the inner bottom of the housing 1 are respectively provided with a sliding groove 16, and the top and the bottom of the partition board 2 are respectively provided with a sliding block 17 slidably connected with the sliding groove 16. The sliding block 17 and the sliding groove 16 are arranged to guide the partition board 2 and position the partition board 2 when the partition board 2 is installed.

Further, as shown in fig. 1, the inner top of the housing 1 is provided with a first stopper 18 and a second stopper 19, the first stopper 18 and the second stopper 19 are located between the humid air inlet 8 and the humid air outlet 9, and the partition 2 is disposed between the first stopper 18 and the second stopper 19. The first stop 18 and the second stop 19 are provided for limiting the partition 2, preventing the humid air from being directly discharged from the humid air outlet 9 without passing through the fixing tube 3.

Further, as shown in fig. 5, the fixed pipe 3 is an elliptical pipe. The fixed pipe 3 is set as an elliptical pipe, so that the interval between the fixed pipes 3 can be reduced, and the coverage surface of the fiber membrane in the fixed pipe 3 is increased. Meanwhile, the space utilization rate inside the shell is improved.

The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the utility model is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art.
