For feed liquid can be melted better, be equiped with auxiliary heating electrode in the dog-hole of the fire-resisting partition between described melting end and the settling section.

The described bushing of being located at the body of heater outside is provided with the bushing heating electrode.

Described bushing is the platinum-rhodium alloy bushing.

In order to make feed liquid more even, and reduce bubble, be respectively equipped with bubbling device in described melting end and the settling section.

The utility model is because with melting end, settling section and homework department separately, disposed heating electrode respectively, and disposed the auxiliary drum bulb apparatus respectively at melting end and settling section, fusing and convection current are strengthened, and fusing is more thorough under the effect of mix heating electrode in stove of production basalt long fiber.It is radial to flowing all around that basalt glass liquid is, can play the effect that stops mix to be pushed ahead, help strengthening and found, reduce the generation of bubble, promote convection current, make the adequate time that has of fusing, clarification and homogenization, the clarification and homogenization more of basalt glass liquid are laid a good foundation for successfully pulling out the basalt long fiber.

Bushing adopts platinum-rhodium alloy to make, and above heating electrode is housed, can carry out adjustment, make the basalt glass liquid temp unanimity of leting slip a remark by bushing, viscosity is constant, provides assurance for successfully pulling out the basalt long fiber.

Kiln of the present utility model has the higher thermal efficiency, the melting capacity height.Stable production process does not need complicated management, and temperature is convenient to regulate in the stove, and flexibility is big, easily realizes whole automation controls.Good work environment, equipment operation noiselessness.

Of the present utility model simple in structure, the cold repair cycle is short.Floor space is little, small investment, and utilizing the utility model to produce the basalt long fiber is the basaltic effective measures of a kind of development and use.

The utility model is described in further detail below in conjunction with accompanying drawing.
