Summary of the invention
This patent provides a kind of basalt fibre electric smelter for above technical problem, solves existing electric smelting furnace and adopts the heated by electrodes mode, and its electrode is soluble in the problem that causes quality product to descend in the basalt fibre fused solution.It is high that the utility model takes full advantage of the Electric heating heat utilization efficiency, and the energy easily guarantees, its heat-processed does not affect the quality of basalt fused solution simultaneously, and performance and the universal basalt fibre production technology that improves basalt fibre had positive effect.
The concrete technical scheme of this patent is as follows:
A kind of all-electric melting furnace of producing basalt continuous fiber, formed by body of heater, wide-u-shaped an electric heating element, high-temperature camera, charging opening, inlet, body of heater, cooled screw feeder, upper of furnace body arranges the wide-u-shaped an electric heating element, high-temperature camera arranges body of heater vision slit place, sealed feed inlet is arranged on the afterbody of body of heater, the cooled screw feeder connects sealed feed inlet, and the body of heater lower curtate arranges the discharging drawing wire machine.
The wide-u-shaped an electric heating element is Si-Mo rod or globars, and wide-u-shaped an electric heating element width is greater than 200 millimeters.
Sealed feed inlet quantity is more than 2 or 2, and described cooled screw feeder quantity is more than 2 or 2.
High-temperature camera connects control terminal and monitors for the working order of control screw feeder and to inner operating.
It is heating unit that the utility model design adopts special U-shaped Si-Mo rod (or globars), is arranged in the smelting furnace top, and the basalt fused solution is carried out surface heating, and U-shaped Si-Mo rod width is generally greater than 200 millimeters.The raw materials mouth is arranged in the smelting furnace afterbody, and the layout that is uniformly dispersed, and raw material can evenly enter smelting furnace like this, and can guarantee that raw material has the longest heat-up time in smelting furnace, guarantees sealing between filling tube and the smelting furnace, and the heat radiation that reduces smelting furnace reduces heat lost by radiation.Smelting furnace is provided with viewing window, take photo in the stove with high-temperature camera, inner operating is monitored, picture is processed basalt fused solution in the Accurate Measurement stove, do not contact like this liquid level and measure, and the operation of control feeding device is to reach the height of basalt fused solution in the accurate control smelting furnace.
The art of this patent can realize that the all-electric melting mode produces basalt fibre, produces high-quality basalt fibre with lower energy consumption, has been specially adapted to raw material resources, and use in the area that supply of electric power is abundant.
