Abstract

The invention discloses a large thermal power combination tank furnace for producing basalt continuous fibers. The large thermal power combination tank furnace comprises a batch feeder, a fusing zone, a homogenizing zone and two forming zones, wherein the discharge hole of the batch feeder is connected at one end of the fusion zone; the other end of the fusion zone is connected with one end of the homogenizing zone; the other end of the fusion zone or the homogenizing zone is connected with a chimney by a flue; one forming zone is connected on each of the left end and the right end of the homogenizing zone; a side-insertion electrode is arranged on the side wall of the fusion zone; the electrode is arranged below the melt liquid surface; a combustor is arranged on the top of the fusion zone; a plurality of uniformly and densely arranged gas nozzles are arranged on the side walls of the forming zones; the gas nozzles are arranged above the melt liquid surface; a plurality of leakage plates are uniformly arranged on the bottoms of the forming zones along the length direction of the forming zones; an air-cooled type heat exchanger is arranged on the flue; a hot air outlet of the air-cooled type heat exchanger is connected with an air inlet of the combustor; and a smoke outlet of the air-cooled type heat exchanger is connected with the chimney.

Description

technical field [0001] The basalt fiber produced by the invention is a high-performance fiber. The production equipment has high thermal efficiency and a large-scale thermal-electricity combined pool kiln, which belongs to the field of inorganic non-metallic material processing. Background technique [0002] Basalt ore is the main ore of volcanic slurry, which has good chemical stability and thermal stability. Basalt melting is different from the batch melting process in glass production, it has no silicate reaction and purification and clarification process. The chemical composition of basalt from the same origin is relatively stable, but the impurity content fluctuates. [0003] The fibers made of basalt have excellent properties: good thermal stability, good corrosion resistance, high tensile strength, high elastic modulus, good electrical insulation performance, etc., and have been widely used in shipbuilding, automobiles, aerospace, aviation, construction It has broad...
