[0002] A fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of electrolyzing water. Hydrogen and oxygen are respectively supplied to the anode and the cathode. After hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external load. A platinum catalyst is a general term for a catalyst mainly composed of metallic platinum and is a catalyst often used in chemical, petroleum, and chemical reaction processes.

[0003] Currently, in the process of preparing a hydrogen fuel cell catalyst, the battery catalyst is mostly pulverized first and then mixed. However, the traditional device for preparing a hydrogen fuel cell catalyst is inconvenient for automatically screening fine particles of the battery catalyst to improve the catalytic efficiency, and it is also inconvenient for automatically quantitatively feeding the catalyst according to the catalytic requirements to prevent excessive feeding from affecting battery preparation. Therefore, there is an urgent need for a device for preparing a hydrogen fuel cell catalyst to solve the above problems. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing device for preparing a battery catalyst is inconvenient for automatically screening fine particles of the battery catalyst and is also inconvenient for automatically quantitatively feeding the catalyst according to the catalytic requirements.

The bottom of the preparation barrel is fixedly connected with a discharge hopper. The device further includes a fine screening mechanism arranged on the feeding baffle. A vertical plate is fixedly arranged at the bottom of the preparation barrel. The device further includes a quantitative discharging mechanism arranged on the vertical plate.

[0006] To smoothly achieve the purpose of facilitating the automatic screening of fine particles of the battery catalyst, the fine screening mechanism includes a connecting seat fixedly connected to the feeding baffle. A screening motor is fixedly arranged on one side wall of the connecting seat. The output end of the screening motor is connected with a driving gear. A driven gear is meshed with the driving gear. A connecting plate is fixedly connected to the edge of the driven gear. The other end of the connecting plate is fixedly connected with a screening box. The other end of the screening box is fixedly connected with a sliding seat. The sliding seat is slidably connected with a slide rail fixedly connected to the feeding baffle.

[0007] In order to smoothly achieve the purpose of facilitating the automatic quantitative feeding of the battery catalyst, the quantitative discharging mechanism includes a pedestal fixedly connected to the bottom of the vertical plate. A threaded rod is rotatably connected between the two side walls of the pedestal. A driving motor for driving the rotation of the threaded rod is fixedly provided on one side wall of the pedestal. A guide rod is fixedly connected between the two side walls of the pedestal. A moving plate is slidably connected through the guide rod. The moving plate is threadedly connected to the threaded rod. A connecting rod is fixedly provided on the moving plate. An opening and closing plate slidably connected to the bottom of the discharging hopper is fixedly connected to the connecting rod.

[0008] Furthermore, a transparent scale plate is fixedly connected to the side wall of the preparation barrel. The bottom of the discharging hopper is provided with a discharging port. A feeding plate fixedly connected to the inner wall of the preparation barrel is provided below the screening box. A splash-proof enclosure is fixedly provided on the top of the screening box.

[0009] Furthermore, the pedestals are symmetrically arranged at both ends of the preparation barrel, and the opening and closing plates are symmetrically arranged at both ends of the discharging hopper.

[0010] Preferably, the gears on the transmission gear are evenly distributed at 90 degrees. The pedestal is arranged in an inclined U shape, and the connecting rod is arranged in an inverted L shape.

[0011] The beneficial effects achieved by the present utility model with the above structure are as follows:
