A kind of production device and production method of basalt fiber

Abstract

The invention discloses a production apparatus and production method for a basalt fiber. The production apparatus comprises an ore melting furnace and a drawing machine; the top of the furnace chamber of the ore melting furnace is successively provided with a feed inlet and a combustor from left to right; the furnace chamber is successively provided with, from left to right, a melting zone, a clarification zone and a blanking runner, wherein the width of the clarification zone gradually narrows along a direction from melting zone to blanking runner, and a detachable platinum channel is arranged below the blanking runner; the right sidewall of the furnace chamber is provided with a smoke discharging channel; a discharge outlet is arranged between the blanking runner and the detachable platinum channel; a bushing plate is installed below the detachable platinum channel, and an oil coating buncher and the drawing machine are successively arranged below the bushing plate; and the detachable platinum channel and the bushing plate are connected with an energizing device. With the production apparatus, basalt fiber production operation is more stable; production cost is reduced; and product quality is improved.

Description

technical field [0001] The invention relates to the technical field of basalt fiber production equipment, in particular to a basalt fiber production device and a production method thereof. Background technique [0002] Basalt continuous fiber is a continuous fiber made of basalt ore as raw material, melted at 1450-1500°C, and drawn at high speed through a platinum-rhodium alloy wire drawing bushing. / Low temperature, acid and alkali resistance, oxidation resistance, radiation resistance, heat insulation and sound insulation, fire and flame retardant and other excellent properties, therefore, basalt fiber can be widely used in fire protection, environmental protection, aerospace, military industry, automobile and ship manufacturing, engineering plastics and construction, etc. field. [0003] The existing disclosed basalt fiber production technology can only produce basalt fiber, but cannot achieve continuous operation and large-scale production. Due to the poor thermal condu...

AI Technical Summary

Problems solved by technology

[0003] The existing disclosed basalt fiber production technology can only produce basalt fiber, but cannot achieve continuous operation and large-scale production. Due to the poor thermal conductivity of basalt, there cannot be a high liquid level in the kiln. There will be a large temperature difference during the position, and it is easy to crystallize, which affects the continuous operation of the fiber, so it cannot be mass-produced, and the production cost is also high.
