Hot air fiber forming system for rock wool production

Abstract

The invention discloses a hot air fiber forming system for rock wool production. The hot air fiber forming system comprises a high-temperature hot air fiber forming four-roller centrifugal machine, and also comprises a liquid-gas mixing center glue spraying device, a centrifugal roller cooling water system, an oil-gas lubricating system, a heat insulation cooling system and a high-temperature high-speed hot air system which are arranged in parallel; an output end of the liquid-gas mixing center glue spraying device is communicated with a center glue spraying inlet through a pipeline; an outputend of the centrifugal roller cooling water system is communicated with a cooling water inlet through a pipeline, the oil-gas lubricating system is communicated with a cavity in a main shaft througha pipeline, the heat insulation cooling system is communicated with a heat insulation cooling water inlet through a pipeline, and the high-temperature high-speed hot air system is communicated with ablow-off air port through a pipeline. The hot air fiber forming system further comprises a glue applying system, the glue applying system is communicated with the liquid-gas mixing center glue spraying device and a peripheral glue applying device through pipelines, the peripheral glue applying device is connected with a spray head, glue is sprayed to the periphery of a centrifugal roller, and mistglue flow is formed. According to the system, fiber forming fiber is small in diameter, low in slag ball content, high in fiber forming rate and more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of rock wool fiber-forming technology and equipment, in particular to a hot-air fiber-forming system for rock wool production. Background technique [0002] In the rock wool production process, the rock wool fiber-forming system is the key process of rock wool fiber production, and the fiber-forming system determines the fiber production, fiber diameter, slag ball content, and uniformity of fiber spray glue in rock wool production. [0003] Fiber-forming principle of rock wool production: [0004] The main raw material is basalt rock, which is melted at high temperature in a melting furnace. After the melt stream flows to the centrifugal roller, it is dispersed into a ring shape. Under the action of centrifugal force, the ring-shaped melt is pressed to the outer edge of the roller wheel. At this time, the thickness of the melt layer is reduced to the surface capacity of the melt itself. A certain limit is ...
