The new type belongs to the technical field of tantalum electrolytic capacitors, in particular, relates to tantalum particle manufacturing equipment. The anode of tantalum electrolytic capacitor is obtained by forming the tantalum aggregate particles into porous tantalum particles and oxidizing the surface of tantalum particles to generate dielectric oxide film. Then the tantalum electrolytic capacitor is obtained by filling the anode with a solid electrolyte and connecting the cathode to the impregnated solid electrolyte. This kind of electricity is easy to be miniaturized, so it is widely used in electronic equipment.
The traditional preparation method of tantalum particles used in tantalum electrolytic capacitors is to use a drum granulator to combine fine tantalum powder with coarse tantalum powder for spherically granulating. The obtained tantalum particles have high packing density and are not easy to be pressed into shape during use, and the obtained tantalum particles have uneven particle size. Tantalum particle manufacturing equipment includes a frame, the frame is arranged above the granulation plate, the granulation plate is arranged on one side above the dispersion plate, the dispersion plate is fixedly connected with the frame through a bracket; A loose material turntable is arranged on the inner bottom wall of the dispersion plate, and a number of loose material blocks are fixed on the upper surface of the loose material turntable. When the loose material turntable rotates, tantalum powder collids with the loose material block to break up the lumps in the tantalum powder. A first motor is fixed in the center of the bottom wall of the dispersion plate, and the output end of the first motor runs through the bottom wall of the dispersion plate and is fixed connected with the rotating center of the loose material turntable to drive the loose material turntable to rotate. One side of the dispersion plate is provided with a hot air duct, which is fixed connected with the frame, and the outlet end of the hot air duct is connected with the side wall of the upper side of the dispersion plate. Accordingly, the side wall of the dispersion plate is also provided with an air outlet, through which hot air is injected into the dispersion plate, and the moisture absorbed on the surface of the tantalum powder is dried by hot air, so that the tantalum powder is in a dry state and the tantalum powder is fully dispersed. Avoid caking in tantalum powder, forming uneven particle size in the granulation process.
Further, a blanking port is arranged on the side wall of the lower side of the dispersion plate, and a cylinder is arranged on the outside of the blanking port. The output end of the cylinder is fixed with a baffle plate matching the shape of the blanking port. The baffle plate is driven by the cylinder to control the drying tantalum powder blanking.
