[0006] The twin-roller kneader is a commonly used nano-zirconia powder kneader at present. The existing nano-zirconia powder kneader mainly uses elliptical kneading rollers. The common defect is: when the kneading material is When kneading in a two-roll kneader, when the viscosity increases, a part of the mixture will stick to the rolls and rotate with the rolls without participating in the mixing.
This affects the effect of mixing and reduces the quality of mixing.

Embodiment Construction
[0028] Such as figure 1 , figure 2 As shown, a mixing device for nano zirconia powder of the present invention includes a mixing box 1, a heating device 6 is installed outside the mixing box 1, and the mixing box 1 is built with nano zirconia For powder 4, two rollers 2 are installed in the mixing box 1, and the two rollers 2 cooperate and rotate in opposite directions, thereby driving the powder 4 to rotate, shear and knead.
[0029] to combine figure 2 As shown, the roller 2 of the present invention is cylindrical, including a rotating shaft 21 and a roller body 22, and several grooves 23 are evenly arranged on the outer circumferential surface of the roller body 22. In this embodiment, the grooves 23 are arranged along the roller body 22. Longitudinal and horizontal opening, grooves 23 are set to 9, considering the mixing efficiency of the powder 4 and not easy to bond, through experiments, the groove width of the groove 23 is preferably 25-30mm, and the groove width of...

The invention discloses a nanometer zirconia powder mixing device. The nanometer zirconia powder mixing device comprises a mixing tank and is characterized in that nanometer zirconia powder is laid in the mixing tank, two rollers are installed in the mixing tank, and are cooperated with each other, each roller is columnar and comprises a rotation shaft and a roller body, multiple grooves are uniformly formed in the outer circumferential surfaces of the rollers, comb plates are arranged above the rollers, and multiple shovels are uniformly arranged at one ends of the comb plates, and the shovels and the grooves are matched. According to the nanometer zirconia powder mixing device, the columnar rollers are adopted, the grooves are formed in the outer circumferences of the rollers and meanwhile are matched with the shovels of the comb plates and drainage holes, so that the problem of powder bonding can be effectively solved, and the mixing efficiency can be effectively improved.
Description
[0001] Technical field: [0002] The invention relates to a mixing device for nano zirconia powder, in particular to the technical field of mixing nano zirconia powder in the production of nano zirconia pins for optical fiber ceramic connection inserts. [0003] Background technique: [0004] At present, nano-zirconia ceramic ferrules are commonly used for optical fiber connection. In the production process of nano-zirconia ceramic ferrules, there must be a process, that is, to mix nano-zirconia powder and a suitable organic carrier evenly to become suitable for injection molding. It is a pin blank with certain fluidity and certain strength, which is convenient for injection molding in the next step. [0005] In the powder of nano-zirconium injection molding, there are not only nano-zirconia zirconium powder, but also several kinds of organic binders, surface modifiers, mixing inducers, lubricants, plasticizers and so on. Since the nano-zirconium powder and the above-mentioned...
