Furnace used for producing basalt continuous filament

Abstract

The invention discloses a furnace used for producing a basalt continuous filament. The furnace used for producing the basalt continuous filament comprises a furnace body, main material channels, a diversion material channel, a feeding device arranged on the top of the furnace body, multiple heating devices which are arranged on the side wall of the furnace body and multiple working units communicated with the diversion material channel. The furnace body is communicated with the diversion material channel through the main material channels. The diversion material channel is in a closed annular shape or a circular arc shape. The diversion material channel is connected with at least two main material channels which are same in length. The connecting points of the diversion material channel and the main material channels are evenly distributed on the diversion material channel. The multiple working units are evenly distributed on the inner side and / or the outer side of the diversion material channel. The furnace has the advantages that the production capacity is high, the stability of the product quality is high, the manufacturing cost is low, the large-scale industrial production of the basalt continuous filament is achieved, and the requirement for the basalt continuous filament of the extensive application of various social fields is met.

Description

technical field [0001] The invention relates to the technical field of basalt continuous fiber production equipment, in particular to a kiln for producing basalt continuous fiber. Background technique [0002] Continuous basalt fiber (CBF for short) is an emerging environment-friendly inorganic fiber material, which has excellent properties such as light weight, high strength, high temperature resistance, acid and alkali corrosion resistance, heat insulation and sound insulation, etc. Wide application, broad market prospect. [0003] Today, the production process of basalt continuous fiber is roughly as follows: natural basalt rock is used as the raw material for the production of basalt continuous fiber, and it is put into the kiln by the feeder, and is melted into liquid by the high temperature environment in the kiln, and the liquid is further clarified and homogenized. The scum layer, basalt melt, and sediment layer are distributed from top to bottom, and then the basal...

AI Technical Summary

Problems solved by technology

Due to small production capacity, large fluctuations in product quality, and high production costs, unit kilns cannot realize large-scale industrial production of basalt continuous fibers, and cannot meet the needs of basalt continuous fibers for wide applications in various fields of society.
