[0002] Perovskite solar cell powder is a key raw material for manufacturing the light-absorbing layer of perovskite solar cells. It is mostly powder with specific crystal structures, such as formamidinium lead iodine and formamidinium cesium lead iodine. Its performance directly affects the photoelectric conversion efficiency of the cell. A mixing process is required during the processing because mixing can adjust the crystal band gap to match the solar spectrum, optimize the particle distribution to reduce thin film defects, and enhance the long-term stability of the cell. The mixing objects mainly include alkali metal salt powders containing cesium and rubidium, perovskite matrix powders of different particle sizes, and metal ion powders containing tin and zinc.

[0003] When mixing equipment is used, the mixing chamber often needs to rotate continuously. However, the existing equipment does not provide sufficient protection and isolation for the rotating chamber, making it difficult for personnel to maintain a safe distance and increasing the risk of collisions and other safety accidents. Therefore, a new perovskite battery powder mixing equipment needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a perovskite battery powder mixing device to solve the problem mentioned in the background art of insufficient protection and isolation of the mixing device during the rotation of the chamber.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a perovskite battery powder mixing device, comprising...

[0006] A base, side frames symmetrically fixed to the top surface of the base, and a compartment rotatably mounted between the two side frames;

[0007] The isolation assembly includes a drum fixed to the top surface of the base and located outside the chamber, a strip groove opened on the top surface of the drum, an isolation curtain elastically wound inside the drum and with its outer end extending out of the strip groove, a fixing strip fixed to the outer end of the isolation curtain, and hanging blocks fixed to both ends of the fixing strip.

[0008] The mounting assembly includes two telescopic rods symmetrically mounted on the front surface of the side frame, and a fixing ring fixed to the head end of the telescopic rods and capable of engaging with the hanging block.

[0009] Preferably, the inner rotating part of the roller is provided with a central shaft, and the isolation curtain is wound around the surface of the central shaft.

[0010] Preferably, the isolation assembly further includes side protrusions fixed to both ends of the drum, and a coil spring is installed on the inner side of the side protrusion, the coil spring being connected to both ends of the central shaft.

[0011] Preferably, the isolation assembly further includes fixing blocks, which are symmetrically fixed at both ends of the drum, and the fixing blocks can be fixedly installed on the base surface by bolts.

[0013] Preferably, the mounting assembly further includes an embedded groove inside the side frame, and the tail end of the telescopic rod is embedded in the embedded groove.

[0014] Preferably, a rotating shaft is rotatably connected between the side frame and the compartment body, and the rotating shaft and the embedded groove are misaligned with each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By installing flexible, retractable isolation components on the base, the isolation curtain can be unfolded when the equipment is in operation. The unfolded isolation curtain is then limited by the attachment components. The isolation curtain is used to protect the outside of the enclosure, providing a clear indication of the safe distance and preventing personnel from getting too close to the enclosure, thus reducing the risk of accidents.
