Centrifugal disc for producing glass wool

Abstract

The invention relates to a centrifugal disc for producing glass wool. The centrifugal disc is characterized in that a curved slot for guiding the flowing direction of glass metal is formed in the bottom surface of the centrifugal disc, and the curve is in the shape of an Archimedean spiral; a main shaft installing hole in the bottom surface of the centrifugal disc is used as the starting end of the curved slot, a lower terminated line of a hole in the inner wall of the centrifugal disc is used as the ending end of the curved slot, and the curved slot is arranged in the same direction as the rotating direction of the centrifugal disc. The curved slot in the shape of the Archimedean spiral is formed in the bottom of the centrifugal disc, and is arranged in the same direction as the rotating direction of the centrifugal disc, therefore, the centrifugal disc has the characteristic of guiding the glass metal to adhere on the lateral wall of the centrifugal disc continuously and evenly so as to prevent the glass metal from generating turbulence in a centrifugal process; the centrifugal fiber-forming effect of the glass wool is significantly improved. The centrifugal disc can be widely applied to the field of preparing the glass wool in different levels, and can provide references for other fields of preparing materials in a centrifugal method.

Description

technical field [0001] The invention relates to a centrifugal disc, in particular to a centrifugal disc for producing glass wool. Background technique [0002] Glass wool has the characteristics of porous, small bulk density, good chemical stability, etc., and has good heat insulation and sound insulation performance. It is the basis for thermal insulation, sound absorption and noise reduction, aerospace, filter cleaning, electronic information, transportation and other fields. Raw materials are used in almost every field of the national economy and national defense industry. The development and application of glass wool is an important symbol of the development level of a country's glass fiber industry. [0003] Since the production of glass wool by centrifugation, it has attracted much attention, especially the key component of this production method - the centrifugal disc, which plays the most important role in the output, quality and process stability of glass wool.

Problems solved by technology

The rotational speed of the centrifugal disc is generally 3000-5000 rpm. At such a high rotational speed, when the liquid glass flows against the bottom of the centrifugal disc, it is very easy to cause turbulent flow of the molten glass in the centrifugal disc, and the flow direction is chaotic and disorderly.

This will not only cause the glass liquid film to cover the inner wall of the centrifugal disc unevenly, but is not conducive to the formation of glass liquid fibers, making the glass wool fibers uneven in thickness and consuming more energy.
