Basalt fiber electric production system

Abstract

The invention discloses an electric production system for basalt fibers. The electric production system comprises a stepped heating unit, an ablation furnace and an electric melting bath kiln which are arranged in sequence; the ablation furnace comprises an ablation inner container, an ablation feeding guide pipe corresponding to the discharging end of the stepped heating unit is fixedly arranged on the upper portion of the ablation inner container, and an ablation discharging guide pipe corresponding to the electric melting pool kiln is fixedly arranged on the lower portion of the ablation inner container. An ablation grate assembly is arranged on the portion, between the ablation feeding guide pipe and the ablation discharging guide pipe, of the ablation inner container, and the ablation inner container is coated with an ablation heat preservation layer. The melting furnace is used for connecting the top and the bottom, electric energy production in the whole process is achieved, the continuous operation capacity and the rock melting capacity are high, the productivity is high, and stable fiber quality can be formed easily.

Description

technical field [0001] The invention relates to the technical field of rock wool production, in particular to a basalt fiber electricity production system. Background technique [0002] Rock wool is widely used in industry, construction, shipbuilding and other fields, and its main component is rock ore fiber. Rock ore fiber is obtained by melting basalt and other materials at high temperature, and then centrifuged in a centrifuge. Among them, basalt fiber is used in a large proportion of rock ore fiber because of its better performance. At present, the production of basalt fiber mainly uses coal burning (such as cupola process) or gas burning (such as burner spraying) to melt basalt at high temperature, but both production methods have obvious defects. One is that the thermal energy utilization rate of the two methods is not high, and the waste of coal or gas resources is serious, and with the increasing shortage of coal and gas resources, the cost of thermal energy resourc...

Problems solved by technology

At this stage, there are also technologies that use electric energy to melt basalt, such as electric melting pool kiln, intermediate frequency furnace and other technologies, but the actual use effect is still not ideal

Specifically, one is that electric energy heating usually uses melted media (such as melted magma or melted metal liquid, etc.) to indirectly heat and melt rocks, and indirect heating is effective for cold materials (normal temperature stones or materials with a temperature lower than The heating capacity of the stone at the temperature in the furnace is relatively weak, and the scab problem is more serious than coal burning and gas burning, and the overall heating and melting time is longer, and the production capacity is lower; For melting, if the heating temperature is low, the problem of crusting and long-term melting still exists; if the heating temperature is high, the stone is easy to stick, and the furnace feed is easily blocked.

The acuteness of these problems makes it impossible for electric energy production to replace the original methods of coal burning and gas burning, and electric energy can only be used in conjunction with gas burning. Electric kiln" invention patent application; or only to further purify the melt obtained in other ways, such as the utility model patent with the announcement number "CN203782029U" and the name "full electric furnace for the production of mineral wool"

In the production of basalt fiber, it is always impossible to use only electric energy to realize the whole process of production
