Description

Technical Field

[0001] The utility model relates to the technical field related to hydrogen drying, in particular to a hydrogen dryer. Background Art

[0002] Hydrogen needs to be dried to maintain its purity and stability, prevent corrosion of equipment and systems, and ensure its safety and efficiency in specific applications. Therefore, a hydrogen dryer is used to dry hydrogen. There is a hydrogen dryer with convenient discharge of desiccant (Publication No.: CN221385861U). When replacing, the placement box is taken out of the drying tower body through a moving part, and the placement plate is opened by moving the movable plate for the user to replace the desiccant, improving the replacement efficiency of the user and reducing the maintenance cost.

[0003] The above has the problem that when replacing the dryer, the placement box needs to be taken out of the drying tower body to replace the desiccant in the placement box. If the placement box is large in volume and the desiccant in the placement box is relatively heavy, it is relatively laborious to take out the placement box, and thus the replacement operation of the desiccant may be relatively inconvenient. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a hydrogen dryer.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A hydrogen dryer includes a drying tower body. A first box body is fixedly connected to the drying tower body. Net plates are fixedly connected to both ends of the first box body. A solenoid valve is installed at one end of the first box body. A frame body is rotatably connected to the first box body through a bearing. A torsion spring is fixedly connected between the frame body and the first box body. A through groove rod is slidably connected to the outer wall of the torsion spring. A cover plate is fixedly connected to the through groove rod. The cover plate is rotatably connected to the first box body through a connecting shaft.

[0007] Preferably, a second box body is installed at one end of the solenoid valve. A cover body is installed on the second box body. A second rubber pad is fixedly connected to the joint where the cover body fits the second box body.

[0008] Preferably, a first air pump and a second air pump are respectively installed at both ends of the drying tower body.

[0009] Preferably, a first rubber pad is fixedly connected to the joint where the cover plate fits the first box body.

[0010] Preferably, the first box body is placed obliquely.

[0011] Preferably, a window body is fixedly connected to the second box body.

[0012] Preferably, two groups of handles are fixedly connected to the cover body.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. Through the cooperation among the first box body, the frame body, the torsion spring, the through groove rod, the cover plate and the electromagnetic valve, the frame body drives the through groove rod and the cover plate to rotate, so that the cover body can be separated from the fit with one end of the first box body. Due to the inclined design of the first box body, the desiccant placed in the first box body can be quickly discharged. Subsequently, the desiccant is replenished into the first box body through the electromagnetic valve, and the replacement operation of the desiccant can be completed. The replacement of the desiccant is relatively labor-saving and convenient, and the working efficiency of hydrogen drying can be guaranteed.

[0015] 2. Through the cooperation between the second box body and the cover body, by pre-storing new desiccant in the second box body, after the desiccant in the first box body is discharged, the desiccant in the second box body can be discharged into the first box body for storage through the electromagnetic valve. The discharge and re-placement operations of the desiccant can be carried out without interruption, which can shorten the replacement time of the desiccant, and then the drying tower body can quickly resume the work of hydrogen drying.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Embodiment 1. Refer to Figures 1 to 5 , a hydrogen dryer, including a drying tower body 1, a first box body 2 is fixedly connected to the drying tower body 1, net plates 3 are fixedly connected to both ends of the first box body 2, and the net plates 3 are used for hydrogen to pass through the first box body 2. A solenoid valve 8 is installed at one end of the first box body 2, and the solenoid valve 8 can discharge the desiccant in the second box body 9 into the first box body 2. A frame body 4 is rotatably connected to the first box body 2 through a bearing, and a torsion spring 5 is fixedly connected between the frame body 4 and the first box body 2. The torsion spring 5 gives the frame body 4 a force to drive the through-channel rod 6 to press the cover plate 7 tightly against the first box body 2. A through-channel rod 6 is slidably connected to the outer wall of the torsion spring 5, and a cover plate 7 is fixedly connected to the through-channel rod 6. The cover plate 7 is rotatably connected to the first box body 2 through a connecting shaft. By rotating the frame body 4, the through-channel rod 6 can be driven to rotate the cover plate 7, and the cover plate 7 can cancel the fitting operation with the first box body 2. The desiccant in the first box body 2 can be quickly discharged, and a new desiccant can be injected into the first box body 2 by using the solenoid valve 8, so that the replacement of the desiccant can be completed, and the replacement is relatively convenient.

[0024] In this embodiment, a second box body 9 is installed at one end of the solenoid valve 8, a cover body 10 is installed on the second box body 9, and the opening of the cover body 10 can supplement the desiccant in the second box body 9. A second rubber pad 15 is fixedly connected to the joint where the cover body 10 fits with the second box body 9, and the second rubber pad 15 is used for sealing the joint between the cover body 10 and the second box body 9. A first air pump 13 and a second air pump 14 are respectively installed at both ends of the drying tower body 1. The models of the first air pump 13 and the second air pump 14 are selected according to actual working requirements. The first air pump 13 and the second air pump 14 can be connected to an external hydrogen transmission pipeline, and then hydrogen can be injected into or discharged from the drying tower body 1. A first rubber pad 12 is fixedly connected to the joint where the cover plate 7 fits with the first box body 2, and the first rubber pad 12 is used for sealing between the cover plate 7 and the first box body 2. The first box body 2 is placed obliquely so that the desiccant in the first box body 2 can be discharged. A window body 11 is fixedly connected to the second box body 9, and the window body 11 is used for observing the quantity of the desiccant stored in the second box body 9. Two groups of handles 16 are fixedly connected to the cover body 10, and the handles 16 are used for taking the cover body 10.

[0025] Working principle of this embodiment: During use, both the first air pump 13 and the second air pump 14 are connected to an external hydrogen delivery pipeline. At this time, the first air pump 13 can inject hydrogen into the drying tower body 1, and the second air pump 14 can extract hydrogen from the drying tower body 1. When hydrogen enters the drying tower body 1, it will pass through the mesh plate 3 and come into contact with the desiccant in the first box body 2. With the moisture removal operation of the desiccant on hydrogen, the hydrogen can be dried. When it is necessary to replace the desiccant in the first box body 2, rotate the frame body 4. The frame body 4 can drive the cover plate 7 to rotate through the through groove rod 6, and the cover plate 7 can cancel the fit with the first box body 2, so that the desiccant in the first box body 2 can be discharged. After the discharge, reattach the cover plate 7 to the first box body 2, and at the same time open the solenoid valve 8, and the new desiccant stored in the second box body 9 can flow into the first box body 2, thereby completing the replacement operation of the desiccant.
