Embodiment

[0068] Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited by these examples.

[0069] will figure 1 with figure 2 The burner of the present invention shown is configured in image 3 In the furnace top of the vertical furnace E of the shown inorganic spheroidized particle production apparatus, the raw material powder cut by the raw material supply machine A is supplied to the burner B and spheroidized in the vertical furnace E.

[0070] Specifically, the raw material supply path 1A uses 20 kg / h of silica powder as raw material powder to use 7.5 Nm 3 / h of oxygen (carrier gas) is transported and introduced into the raw material dispersion chamber 4A through the powder dispersion plate 2. In addition, the LPG as fuel gas is reduced to 5Nm from the fuel supply path 5A. 3 / h is introduced into the combustion chamber 8, which is 20Nm from the primary oxygen supply path 6A and the secondary oxygen supply...

Abstract

A burner for production of inorganic sphericalized particles comprising a raw material powder supply channel for supplying of raw material powder with the use of oxygen or an oxygen-enriched air as acarrier gas; a powder dispersion plate with a multiplicity of small perforations fitted to a downstream end of the raw material powder supply channel; a raw material dispersion chamber defined by a dispersion pipe fitted to a downstream end of the powder dispersion plate; a fuel supply channel disposed around the outer circumference of the raw material powder supply channel; an oxygen supply channel disposed around the outer circumference of the fuel supply channel; and a combustion chamber disposed downstream of the raw material dispersion chamber, the combustion chamber having its inside diameter increasing along the downstream direction and communicating with the fuel supply channel and oxygen supply channel.

Description

Technical field [0001] The present invention relates to a burner used in the production of inorganic spheroidized particles, an inorganic spheroidized particle production device using the burner, and a method for producing inorganic spheroidized particles using the device, and the resulting spherical particles. Background technique [0002] Inorganic spheroidized particles are particles obtained by melting and crushing raw material powder in a high-temperature flame and spheroidizing by surface tension. For example, high-purity spherical silica using silica as a raw material is widely used as a filling material for epoxy sealing materials of semiconductor elements. By spheroidizing, the fluidity of the filling material can be improved, high filling, and abrasion resistance can be obtained. Improve various advantages. In addition, in this specification, the inorganic spheroidized particles may be merely described as spheroidized particles. [0003] For the production of inorganic ...
