Description
Technical Field
The utility model relates to non-woven fabric equipment, in particular to an energy-saving melt conveying pipeline.
Background
In the field of non-woven fabrics of textile machinery, there are two processes for manufacturing non-woven fabrics, one is a spunbonding method, namely, polypropylene or polyester chips are heated to 220 ℃ to be melted, the melt is metered and enters a spinning box, the melt is uniformly distributed in the spinning box and is spun through a spinneret plate, the whole process is similar to a 'press hele' process, the spun filaments are cooled through cold air and are paved on a net belt, and then the net belt is hot-rolled into the spunbonded fabrics through a hot rolling mill; the other is a melt blowing method, namely, polypropylene or polyester chips are heated to 220 ℃ to be melted, the melt is metered and enters a spinning box, the melt is uniformly distributed in the spinning box, and the melt is spun through a spinneret plate, but is not cooled again, and is spread on a mesh belt through hot air drafting, and the fibers are self-bonded into cloth in a hot state. In both processes, the melt flows between metering and spinning beams through steel pipes, which carry the melt flow, we call the melt pipe. The steel pipe needs to be heated and insulated, otherwise, the melt can not flow after solidification, and normal spinning production can not be carried out.

When the temperature decreases, heating is continued. Since the temperature difference of the melt directly affects the quality of the product, the temperature control accuracy is required to be ±1 ℃. The heating power of the pipe 11 is also greater, substantially around 3 kw per meter length, due to the higher temperature of the melt. Because the heat dissipation state (or heat load) is different on the whole pipeline 1 length in the operation, the adjacent heating areas are mutually influenced, and the heat conduction of steel is slow, in the actual operation, in order to enable the melt to reach 220 ℃, the heating tile is often heated to 250 ℃, the longitudinal length of the pipeline is greatly different, the temperature is measured at different sampling points sometimes, the temperature difference can reach about 3 ℃, the temperature of the melt is directly influenced, and the spinning quality is also influenced.
