Mortar metalevel particle disperser

Abstract

The invention provides a mortar metalevel particle disperser. The mortar metalevel particle disperser has good stirring effect, good mixing and dispersion effect and higher impact force and shear force, huddle silicon carbide particles can be effectively dispersed, the stirring time is short, and the unit time capacity can be improved. The mortar metalevel particle disperser comprises a stirring container, wherein a central rotating shaft is arranged inside the stirring container, and an upper paddle and a lower paddle are arranged on the central rotating shaft. The mortar metalevel particle disperser is characterized in that a high-speed stirrer is arranged in the stirring container; the high-speed stirrer comprises a disc-type zigzag impeller, a rotary table rotating shaft and a power device; the disc-type zigzag impeller is arranged on the internal side of the stirring container; the disc-type zigzag impeller comprises a rotary table, an upper zigzag plate and a lower zigzag plate; the center of the rotary table is connected with the rotary table rotating shaft; the upper end of the rotary table rotating shaft is externally connected with the power device; and the rotary table rotating shaft is positioned on one side of the central position of the stirring container and is eccentrically arranged.

Description

technical field [0001] The invention relates to the technical field of silicon chip cutting, in particular to a mortar element-level particle disperser, and the invention also provides a high-speed mixer. Background technique [0002] In the cutting of silicon wafers in the prior art, the silicon rods are cooled by spraying mortar on the silicon rods through the nozzle during the slicing process. Mortar is one of the main auxiliary materials for cutting silicon rods by the silicon wafer cutting machine, and its quality depends on the An important factor in the yield of diced silicon wafers. The mortar is obtained by mixing and stirring silicon carbide micropowder and cutting fluid, and the stirring effect is very important for the final quality of the mortar. [0003] For existing mixing devices see figure 1 , the stirring container is equipped with upper and lower two-section stirring paddles. After the sand and liquid are mixed, they need to be stirred at a constant spee...

AI Technical Summary

Problems solved by technology

[0004] ① The mixing effect is average, if there is agglomeration in the mortar, it is basically impossible to break up again;

[0005] ② The overall circulation degree of the mortar in the mortar bucket is low;

[0006] ③Longer stirring time required
