This utility model belongs to the field of aluminum phosphide tablet production technology, specifically relating to a pressing device for aluminum phosphide production. It includes a base, a storage box, and a telescopic pressure plate, as well as a forming disc and a storage cylinder. The forming disc is located inside the protective cylinder. A top plate, which mates with a groove on the top surface of the forming disc, is installed inside the forming disc via an electric telescopic rod. A pressure plate, which mates with the forming disc, is installed on the bottom plate of the telescopic pressure plate via a spring telescopic rod. The storage cylinder, which communicates with the bottom opening of the protective cylinder, is located on the base. By setting up the forming disc, pressure plate, and multiple feeding pipes, multiple aluminum phosphide tablets can be formed simultaneously, improving the production efficiency of aluminum phosphide tablets. By setting two fans on the protective cylinder, one fan, connected to a collection box, is used to collect the powder inside the protective cylinder, and the other fan is used to blow the formed aluminum phosphide tablets, enabling the simultaneous discharge of multiple tablets.

This invention relates to an intelligent robot and method for applying aluminum phosphide to grain warehouses. The intelligent robot includes a walking chassis and a first manipulator and a second manipulator mounted on the chassis. The first manipulator has a flip-up pesticide storage and dispensing assembly connected to its end. The assembly includes a storage shell and a dispensing roller in a bottom slot. The first manipulator grips the pesticide bottle, and the second manipulator opens and closes the cap. By flipping the entire manipulator, the bottle is docked with the storage shell. Through changes in the manipulator's spatial posture, the robot utilizes gravity to achieve lossless return and sealed recovery of remaining pesticide. This invention solves the technical problems of pesticide jamming, uneven distribution, and difficulty in recovering highly toxic residues in existing technologies, achieving inherent safety and efficient, even application during fumigation operations.

The application provides a composite current collector, a preparation method thereof and a negative electrode-free battery. The composite current collector comprises a current collector substrate, and an aluminum fluoride layer, an aluminum phosphide layer and a conductive layer which are sequentially arranged on at least one side surface of the current collector substrate. The composite current collector provided by the application has improved sodium affinity and reduced risk of interface side reaction by the aluminum fluoride layer covering the current collector substrate. The sodium nucleation overpotential is reduced by the aluminum phosphide layer, thereby further improving the sodium affinity. The current distribution and sodium deposition effect are optimized by the conductive layer. Therefore, the composite current collector has excellent sodium deposition uniformity, the negative electrode-free battery containing the composite current collector has high initial coulombic efficiency and excellent cycle stability. In addition, the composite current collector has the advantages of simple structure, easily available raw materials and easy realization of large-scale production.
