Abstract
The utility model provides a device for ultraviolet irradiation of spherical aluminum powder surfaces to generate alumina films, belonging to the metal powder surface treatment technology field. The device comprises three parts of a material conveying system constituted by an air fan and a stainless steel pipeline, a stainless-steel ultraviolet irradiation chamber, and a stainless-steel material receiving tank. A high-power ultraviolet irradiating lamp is arranged in the ultraviolet irradiation chamber. An air particle conveying pipeline in the irradiation chamber is a highly-transparent quartz glass pipe. Two ends of the irradiation chamber are provided with an air inlet and an air outlet. The interior of the chamber is ventilated via the fan at the air inlet so as to reduce the temperature. Spherical aluminum powders that generate alumina films enter into the material receiving tank via an output pipeline of the irradiation chamber. The material receiving tank is a stainless-steel cylindrical tank body and has an inverted cone-shaped lower end, the lower portion of which is connected with a bufferfly valve as a material outlet valve. The upper portion of the material receiving tank is connected with an exhaust pipeline. A piece of filter cloth is arranged between the pipeline and the tank body. The spherical aluminum powders that generate the alumina films are separated from the air by air particle mixtures via the filter cloth. The air is discharged from the exhaust pipeline of the material receiving tank, and the spherical aluminum powders that generate the alumina films remain in the material receiving tank, and the spherical aluminum powders with the alumina films are let out via the material outlet valve. A casing of the material receiving tank is equipped with grounding wires with a resistance less than 3 ohms, so as to eliminate the static electricity generated by the spherical aluminum powders.
Description
Technical field
The utility model is to produce the device that the crystal silicon solar batteries back electrode is used with surface of ball aluminum powder activated alumina film; Solve surface alumina oxide film content and active out of contior problem in the ball aluminum powder production process, belong to the metal-powder technical field of surface.
Background technology
Back electrode of solar cell need generate the pellumina that certain activity is arranged on the surface with ball aluminum powder; Prevent that aluminium and solvent, auxiliary agent from reacting in configuration during electrocondution slurry, the slurry of ball aluminum powder preparation during with the crystal silicon sintering formation vitreum prevent that aluminium and silicon from directly reacting the high-resistance alusil alloy body of formation and silicon is had P type doping function.Now the ball aluminum powder surface generate the method for pellumina be aluminium liquid with in inert gas (as: nitrogen) the pneumatic nebulization globulate aluminium powder process, through the certain content oxygen of increase in inert gas, aluminium liquid pearl and oxygen generation oxidation reaction form during atomizing.The pellumina that produces like this is that high-temperature oxydation generates, and activity is very low, and uncontrollable degree of oxidation.
Summary of the invention
The conveying system that device is made up of blower fan and pipeline, stainless steel ultraviolet ray exposure cell, three parts of stainless steel rewinding jar constitute.The ultraviolet ray exposure cell is the casing of stainless steel; The high-power ultraviolet lamp of wavelength 185nm is housed in the exposure cell; Gas grain conveyance conduit in the exposure cell is high transparent quartz glass tube; Ultraviolet ray sees through quartz glass tube and shines on the gas grain mixture, and ozone and aluminium powder react under nitrogen protection atmosphere, generates pellumina; The two ends, exposure cell have air inlet and air outlet, lower the temperature to room ventilation through the fan of air inlet; The ball aluminum powder that generates pellumina gets into the rewinding jar through exposure cell's output channel, and the rewinding jar is the column type tank body that stainless steel is processed, and the lower end is the back taper body, and the cone bottom is connected to butterfly valve as the discharging valve; Rewinding jar top is connected to discharge duct; Between pipeline and the tank body filter cloth is installed; Gas grain amalgam separates the ball aluminum powder that generates pellumina through filter cloth with gas, gas is discharged from rewinding jar discharge duct; The ball aluminum powder that generates pellumina is stayed in the rewinding jar, has the ball aluminum powder of pellumina to emit through the bleeder valve door knob; The rewinding tank shell is equipped with the earth connection of resistance＜3 ohm, and the static that produces ball aluminum powder eliminates.
This device is to be that ball aluminum powder generates pellumina under cryogenic conditions; Active high; And can control the content that ball aluminum powder surface alumina oxide film generates through power, adjustment ozone and the content of aluminium powder of adjustment blower fan wind speed change ultraviolet irradiation time, adjustment ultraviolet lamp.
