Description
Technical Field
The application belongs to the technical field of industrial production equipment, and particularly relates to a device for producing basalt continuous fibers.
Background
The wu-rock fiber material is a high-performance green industrial material which is produced by using specific basalt formed by volcanic eruption as a raw material to produce continuous fibers, rock wool, fine scales and other products, has the advantages of good comprehensive performance, high cost performance and the like, does not produce toxic substances in the normal production and processing process, and does not discharge waste gas, waste water and waste residues. The basalt fiber product mainly comprises pure basalt wool and basalt continuous fiber. The basalt continuous fiber is golden brown in color, has a series of performance characteristics of high temperature resistance, corrosion resistance, wear resistance, radiation resistance and the like, has the performance between high-strength S glass fiber and alkali-free E glass fiber, and can completely replace glass fiber and even expensive carbon fiber and aramid fiber in certain application fields. The production process of the basalt continuous fiber comprises feeding, melting and drawing. The melting process of basalt ore is a thermochemical reaction process, so gas escapes, and because the basalt melt is very viscous, some bubbles cannot penetrate through the surface of the melt and only remain in the melt. Drawing of the fibers is made difficult by the presence of some unmelted particles, crystallized fragments, and bubbles that fall through the holes of the bushing. After the basalt ore is added to the melting furnace, the ore particles start to sink into the melt (the ore density is large), and since the melt is opaque to heat radiation and the internal temperature of the melt is lower than the surface temperature thereof, the melting process of the basalt ore is performed at a temperature lower than the surface temperature of the melt, and thus it is very difficult to melt the basalt ore at the deep part of the melt. Because basalt has high melting point, poor heat permeability, high viscosity and easy crystallization, a bushing is easy to block, wire drawing interruption is caused, and crystallization can influence the mechanical properties (such as rigidity, strength and the like) of fibers, whether raw materials can be uniformly and continuously added into a kiln is very important for the melting efficiency of the whole kiln and the homogenization of the melt temperature. Therefore, the development of the high-efficiency homogenizing feeding device is a very important key technology in the drawing production process of the basalt continuous fibers.
The charging hole of the traditional kiln for producing basalt continuous fibers is arranged on the left and right of the middle position of the side wall of the kiln, and raw materials continuously fall into the furnace body through the furnace wall opening through the charging device, so that charging is completed. The feeding mode has the following disadvantages: the side wall feeding mode easily causes the raw materials to be accumulated on the side close to the furnace wall, and because the depth of the basalt melt in the furnace body is shallow, the added raw materials are not melted in time, so that accumulation is generated. The raw materials of the charging opening fall into the furnace at a fixed position, so that the temperature of the melt at the position is lower, and meanwhile, the heat permeability of the basalt melt is poorer, so that the surrounding heat cannot be timely supplemented, and the melting efficiency at the position is lower. Because the feeding position is fixed, the raw materials are abraded to the furnace wall for a long time, so that the furnace wall is abraded seriously, the erosion phenomenon of the fused mass to the furnace wall is accelerated, the erosion speed of the furnace wall at the feeding side is accelerated, the heat preservation effect of the furnace body is influenced, and the whole service life of the furnace body is also influenced.
Accordingly, there is a need for an improved apparatus for producing basalt continuous filament.
