Abstract: An automatic transport device for cleaning machines includes a transport base. A lifting-lowering assembly and a tray are provided on the transport base. The tray is connected to the transport base through the lifting-lowering assembly, and can be driven by the lifting-lowering assembly to reciprocate in a height direction. A top surface of the tray is provided with a translation assembly for transferring the shelf to the transport platform. A first mounting cavity is provided at each of front and rear ends of the tray. The translation assembly is connected to a side wall of the first mounting cavity. A second mounting cavity is provided at each of right and left ends of the tray. The second mounting cavity is provided with a limiting assembly, a lifting-lowering sensing assembly and a distance sensing assembly. An interactive system is provided in the transport base.

Abstract: The present invention provides a method for preparing fluorine/nitrogen co-doped graphitized carbon microspheres with high volumetric specific capacitance, which is a simple process with moderate reaction conditions, high reproducibility, and low costs. The fluorine/nitrogen co-doped graphitized carbon microspheres prepared according to the present invention have a very high density, exhibit good electrochemical properties in an alkaline environment, as well as very high volumetric specific capacitance and good cyclic stability, and is of great importance in improving the properties of the electrode material for a capacitor.

Abstract: A method for preparing fluorine/nitrogen co-doped graphitized carbon microspheres with high volumetric specific capacitance, mainly comprises: successively adding a carbon source, a nitrogen source, a fluorine source and a surfactant to a reactor under a nitrogen atmosphere, and stirring for 10-30 minutes before sealing the reactor; placing the reactor into a crucible furnace, heating at 300-600° C., for 6-48 hours, followed by naturally codling the reactor to room temperature and removing the reaction mixture therefrom; successively washing the resulted reaction mixture with absolute ethanol, 0.1 M-5 M diluted hydrochloride acid and distilled water for 3-6 times, filtering, and placing powder thus obtained in a vacuum oven and drying in vacuum at 60-100° C. for 6-12 hours. The present invention provides a simple process with moderate reaction conditions, high reproducibility, and low costs.
