SULFUR MATERIAL SPRAYING APPARATUS

摘要

The present invention comprises: a material tank 1 which contains therein a melted sulfur material as a spraying material; a warming heater 2 which is made temperature-adjustable so as to heat an outer peripheral portion of the material tank 1 within a setting temperature range equal to or higher than sulfur melting point and to retain the sulfur material in the material tank 1 in a melted state; and a spray nozzle 3 which is integrally mounted to the material tank 1 while being connected to a material outlet port on a lower end portion of the material tank 1 and is supplied with the compressed air, to inject the sulfur material in the material tank 1 together with the compressed air, wherein the sulfur material in the melted state is sprayed on a working surface. As a result, the spraying material comprised of the sulfur material which is solid at room temperature while it is melted to become a fluid state upon being heated to a temperature within a preset temperature range of which a lower limit is set to be equal to or above a melting point of the sulfur material can be consecutively sprayed on the working surface.
