[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A waste gas recovery device for a pressure swing adsorption (PSA) hydrogen generator includes a base plate 1, a body 3, and a protective mechanism. The body 3 is located on top of the base plate 1. An air inlet assembly 4 is located on the top of the body 3, and an air outlet assembly 5 is located at the rear of the body 3. The protective mechanism includes a protective frame 6, a positioning block 7, a switch door 8, a limiting plate 9, a first sliding groove 10, a first sliding block 11, a second sliding groove 12, a second sliding block 13, and a limiting block 14. The protective frame 6 is fitted onto the outside of the body 3. An opening is formed at the top of the protective frame 6, the size of which is larger than the size of the air inlet assembly 4. The switch door 8 is hinged to the front of the protective frame 6. The first sliding groove 10... A first slider 11 is slidably connected to the first slide groove 10 at one end, and the other end of the first slider 11 is connected to one end of the limiting plate 9. The limiting plate 9 has a circular hole, the size of which is larger than the size of the air outlet component 5. The second slide groove 12 is formed on the first slider 11. One end of the second slider 13 is slidably connected to the second slide groove 12, and the other end of the second slider 13 abuts against the protective frame 6. One end of the limiting plate 9 is set on the switch door 8. One end of the positioning block 7 is connected to the protective frame 6, and the other end of the positioning block 7 extends into the base plate 1.

[0023] In use, first place the equipment in the designated location. Then, the exhaust gas is discharged into the body 3 through the air intake component 4. The body 3 is a conventional exhaust gas recovery device for pressure swing adsorption hydrogen generators on the market, containing components such as a filtration mechanism and a heat exchange mechanism, which will not be described in detail here. By opening the switch door 8, the body 3 in the protection mechanism can be operated. After the body 3 has finished treating the exhaust gas, it can be discharged through the air outlet component 5. The protective frame 6, switch door 8, and limit plate 9 can protect the body 3 from being bumped or damaged by external objects. When the protection mechanism is damaged and needs to be replaced after long-term use, first open the switch door 8. Figure 1The process involves separating the limiting block 14 from the second slider 13, then pushing the second slider 13 on the second slide groove 12 to separate the second slider 13 from the protective frame 6. Next, the limiting plate 9 is pushed, causing the first slider 11 to slide on the first slide groove 10, moving the limiting plate 9 to a suitable position and separating it from the air outlet assembly 5. The limiting plate 9 has a circular hole larger than the air outlet assembly 5, allowing the limiting plate 9 to pass through the air outlet assembly 5. Then, the protective frame 6 is lifted upwards, separating the positioning block 7 from the base plate 1 and separating the top of the protective frame 6 from the air inlet assembly 4. Continuing to lift the protective frame 6 upwards separates the protective mechanism from the body 3, allowing a new protective mechanism to be installed. The top of the protective frame 6 has an opening larger than the air inlet assembly 4, allowing the protective frame 6 to pass through the air inlet assembly 4. The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to actual conditions. New protective mechanisms can be purchased from manufacturers and are not described in detail here.

[0024] The above-mentioned equipment is inconvenient to move. In order to solve this problem, in this embodiment, the bottom of the base plate 1 is provided with a pulley mechanism 2. There are several pulley mechanisms 2, and a brake assembly is provided on the pulley mechanism 2. The brake assembly can fix the pulleys on the pulley mechanism 2.

[0025] The above-mentioned equipment is inconvenient to operate. In order to solve this problem, in this embodiment, the front of the body 3 is provided with a controller 15, and the controller 15 is electrically connected to the body 3.

[0026] The stability of the pulley mechanism 2 is poor. To solve this problem, in this embodiment, several pulley mechanisms 2 are symmetrically arranged.

[0027] To improve the positioning effect, in this embodiment, the positioning block 7 is provided in two parts.

[0028] To improve the connection effect, in this embodiment, the positioning block 7 is welded to the protective frame 6.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
