Abstract
A mixing apparatus which prevents erosion of left and right side walls 12a 12b for a flow path 12 for a molten substance of high temperature M and homogenizes the molten substance of high temperature while occurrence of air bubbles is prevented, wherein there are a plurality of mixing units 11 in the flow path 12; an even number of pairs of mixing units 11 are arranged symmetrically with respect to the center line in a longitudinal direction of the flow path 12 and the gap s between a left side wall or a right side wall and an outer peripheral edge of a mixing blade 14 is determined to be 0.04-0.1 times as much as the distance W between the left and right side walls 12a, 12b.
Claims8
A mixing apparatus for a molten substance of high temperature which comprises a plurality of mixing units for mixing a molten substance of high temperature in a flow path for passing the molten substance, which is defined by left and right side walls, wherein the plurality of mixing units are arranged in a side-by-side relation so as to traverse the flow path, and mixing blades of adjacent mixing units are rotated in a state of substantially meshing with each other, said mixing apparatus being characterized in that a minimum gap between a left side wall or a right side wall and an outer peripheral edge of a mixing blade is 0.04-0.1 times as much as a distance between the left and right side walls, each of the mixing blades having a wedge shape in cross section in the observation of the blade from a direction tangential to a circle of rotation of the blade wherein a working face which inclines upward from a front part to a rear part with respect to a direction of rotation of the blade, is formed.
A mixing apparatus for a molten substance of high temperature which comprises a plurality of mixing units for mixing a molten substance of high temperature in a flow path for passing the molten substance, which is defined by left and right side walls, wherein the plurality of mixing units are arranged in a side-by-side relation so as to traverse the flow path, and mixing blades of adjacent mixing units are rotated in a state of substantially meshing with each other, wherein a minimum gap between a left side wall or a right side wall and an outer peripheral edge of a mixing blade is 0.04-0.1 times as much as a distance between the left and right side walls, wherein each of the mixing units has a rotating shaft which has an outer peripheral surface in its lower portion, with which mixing blades for mixing the molten substance of high temperature are attached;
- an upper portion of the rotating shaft is supported by a plurality of vertically spaced bearing members and an upper end of the rotating shaft is inserted into a gear box;
- a sleeve is disposed between the vertically spaced bearing members so as to surround the rotating shaft;
- a lubricant circulation passage is formed to circulate lubricant from a lower bearing member through the sleeve, an upper bearing member and the gear box to the lower bearing member, and a pump is provided to circulate the lubricant through the lubricant circulation passage.
