Technical Field
The invention relates to the technical field of ceramic rod production, in particular to a ceramic rod production process for medical ceramic processing.
Background
The development history of the ceramic is an important component of the Chinese civilization history, China, as one of four civilization ancient countries, makes remarkable contributions to the progress and development of the human society, wherein the invention and the development of the ceramic have unique meanings, and the medical ceramic rod in the prior art has poor wear resistance and surface quality. Meanwhile, the existing polishing equipment cannot simultaneously polish a plurality of ceramic rods through one ceramic disc with high efficiency in the production process, and meanwhile, the cleaning roller has poor surface cleaning effect on the ceramic rods in the cleaning process, so that the situation of cleaning dead corners is easy to occur.
Disclosure of Invention
The invention aims to provide a ceramic rod production process for medical ceramic processing, which solves the following technical problems: (1) the ceramic rod material is added with zirconia whiskers, so that the strength of the ceramic rod can be effectively improved, and meanwhile, the added raw materials such as sea sand, soapstone, diatomite and modified clay can obviously improve the wear resistance of the ceramic rod, and the prepared ceramic rod has good wear resistance, high strength, high temperature resistance, strong acid and alkali corrosion resistance and high surface quality, is suitable for industrial projects such as medicine and fine chemical engineering, has a volume density of more than 6.00g/cm3 and no pits or scratches on the surface, and has a wear resistance of 2/10 ten thousand hours according to JC/T2345-; (2) the ball screw is driven to rotate by adjusting the output shaft of the motor, the ball screw drives the first grinding chamber and the second grinding chamber to move reversely, and then the two round shells move reversely, a plurality of semi-finished ceramic rods are placed between the corresponding rotary cylinders on the two round shells, then the output shaft of the motor is adjusted to rotate reversely, the two round shells move oppositely until contacting with each other, the guide cylinder piston rod in the rotary cylinder pushes the guide block, the guide block drives the two second rotary rods to rotate, the two second rotary rods are matched with the two first rotary rods to drive the guide shell to move, the conveying belt on the guide shell contacts with the surface of the semi-finished ceramic rods, and then the three conveying belts on the three guide shells in the rotary cylinders limit the semi-finished ceramic rods, the output shaft of the conveying motor drives the driving belt pulley to rotate, the two belt pulleys drive the conveying belt to rotate, the driving motor is started, and, the outer gear drives the circular shell to rotate, the mounting motor is started, the output shaft of the mounting motor drives the inner gear to rotate, the inner gear drives the rotary cylinder to rotate, the rotary cylinder drives the semi-finished ceramic rod to rotate, the polishing motor is started, the output shaft of the polishing motor drives the polishing disc to rotate, the conveying belt conveys one end of the semi-finished ceramic rod to the position of the polishing disc in the polishing chamber I, the polishing disc polishes one end of the semi-finished ceramic rod, through the structural arrangement, the polishing equipment can polish a plurality of ceramic rods simultaneously, only one polishing disc needs to be arranged when the requirement for polishing the plurality of ceramic rods simultaneously is met, the polishing efficiency of the ceramic rods is effectively improved, and the number of polishing discs needed when the plurality of ceramic rods are polished is reduced; (3) the water in the water tank is pumped by a water pump and is conveyed to a cleaning nozzle through a right-angle pipe, the cleaning nozzle cleans one end of a semi-finished ceramic rod, sewage generated in the cleaning process flows into a collecting tank, a circular shell drives a rotary cylinder to rotate to the bottom after one end of the semi-finished ceramic rod is polished, a driving motor is turned off, a conveying belt conveys one end of the polished semi-finished ceramic rod to a position between two cleaning rollers, the cleaning motor is turned on, an output shaft of the cleaning motor drives a central gear to rotate, the central gear drives a planetary gear to rotate in an annular shell, the planetary gear drives a rotary rod to rotate, the rotary rod drives the cleaning rollers to rotate, the two cleaning rollers clean one end of the semi-finished ceramic rod, the operations are repeated after the cleaning is completed, the semi-finished ceramic rod is conveyed into a polishing chamber II to be polished and cleaned, and the ceramic, through the structure setting, this equipment of polishing can polish and cleaning to the porcelain rod both sides respectively, and the processing of porcelain rod both ends is gone on in two polishing indoorly respectively, and two cleaning rollers can evenly rotate on the porcelain rod surface when clean and clean, prevent clean dead angle when improving clean efficiency, and is clean effectual.
The purpose of the invention can be realized by the following technical scheme:
a production process of a ceramic rod for processing medical ceramics comprises the following steps:
the method comprises the following steps: weighing 55-90 parts of corundum powder, 14-20 parts of zirconia whiskers, 4-8 parts of nano silicon carbide, 0.8-1.4 parts of boric acid, 10-15 parts of sea sand, 5-8 parts of soapstone, 8-12 parts of kieselguhr, 10-18 parts of modified clay and 250-400 parts of absolute ethyl alcohol;
