[0022] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0023] like Figure 1 As shown, as a copper-based catalyst powder preparation device of the utility model, it includes a reactor 1, a through hole is opened on one side of the top of the reactor 1, and a sealing plug 2 is plugged in the through hole, through which the solution and the reactant are introduced and discharged, and the through hole is sealed by the sealing plug 2 to ensure the normal and stable progress of the reaction, a rotating rod 4 is rotatably arranged in the middle of the reactor 1 and passes through the reactor 1, a driven gear 6 is fixed on the top of the rotating rod 4, and a driving member 3 is fixed on the other side of the top of the reactor 1, and the driving member 3 is set as a driving motor, and the output end of the driving member 3 is connected to the driving gear 5, and the driving gear 5 is connected to the driven gear 6. The rotating rod 4 is meshed with each other, and a fixing plate 8 in contact with the bottom of the reactor 1 is fixed at the lower part of the rotating rod 4. A limiting ring 7 is fixed on the rotating rod 4. The limiting ring 7 is located in the reactor 1 and is in contact with the top of the reactor 1. The stability of the rotating rod 4 is ensured by the limiting ring 7. The driving gear 5 is driven to rotate by the driving member 3, thereby driving the driven gear 6 to rotate. The driven gear 6 drives the rotating rod 4 to rotate and drives the fixing plate 8 to perform stirring. Then, the rotating rod 4 is driven to rotate by the driving device composed of the driving member 3, the driving gear 5 and the driven gear 6, so as to avoid the driving member 3 directly driving the longer rotating rod 4 to rotate and causing insufficient stability.

[0024] like Figure 2 As shown, a movable plate 9 is provided on one side of the fixed plate 8 and the rotating rod 4, and a square slide groove 10 is provided on the fixed plate 8 and the surface where the rotating rod 4 and the movable plate 9 are attached, and a slider 11 slidably connected to the slide groove 10 is fixed on the movable plate 9, and the movable plate 9 is limited in the front and rear directions by the sliding connection between the movable plate 9 and the fixed plate 8, and the movable plate 9 is limited in the left and right directions by the sliding connection between the movable plate 9 and the rotating rod 4, thereby improving the stability of the limitation, and the movable plate 9 is configured as a hollow plate made of plastic foam, and the sides of the fixed plate 8 and the movable plate 9 are both attached to the inner wall of the reactor 1, and the top surface of the movable plate 9 is driven by buoyancy to be not lower than the surface of the solution, so that the height of the stirring plate formed by the fixed plate 8 and the movable plate 9 is always not less than the height of the solution, and then when the rotating rod 4 rotates to drive the fixed plate 8 and the movable plate 9 to rotate, the solution can be fully stirred, which can significantly improve the reaction rate.

[0025] like Figure 3As shown, the slider 11 can be set as a square block, and the two sides of the slider 11 are in contact with the two sides of the slide groove 10. The square slider 11 is in surface contact with the square slide groove 10 to improve the stability of the connection. Figure 4 As shown, the slider 11 can also be set as a trapezoidal block. The area of ​​the end of the slider 11 that is in contact with the moving plate 9 is the largest, and the two sides of this end are in contact with the two sides of the slide groove 10. The trapezoidal slider 11 realizes line contact with the square slide groove 10, reducing the contact area and thus reducing the friction, which is conducive to the buoyancy driving the moving plate 9 to slide. Figure 5 As shown, the slider 11 can also be set to a truncated cone shape. The diameter of the end of the slider 11 that is in contact with the movable plate 9 is the largest, and the two sides of this end are in contact with the two sides of the slide groove 10. The truncated cone-shaped slider 11 is used to achieve point contact with the square slide groove 10, further reducing the contact area and further reducing the friction. A variety of implementation methods can be selected according to actual conditions to increase the scope of application.
