Recently, Hengtian Heavy Industry newly developed an 80,000-ton-year viscose staple fiber post-processing production line to complete the assembly and test run in the factory, and passed mechanical identification to Chengdu Liya Fiber Co., Ltd. The successful development of the production line marks the birth of the world's largest capacity viscose staple fiber post-processing production line in China. It has provided strong support for high-capacity high-end viscose equipment markets at home and abroad, and also reflects Hengtian’s heavy work as a national team of textile machinery. Strength. The project has a total of 14 kinds of unit machines, including electrical control and process flow. The 80,000 t/y post-processing production line developed this time mainly includes a 4m width refiner combined machine and a 3.8m width drying combiner, both of which are currently the world's largest wide-ranging viscose refiners and dryers. machine. Other process parameters include a conveyor speed of 4.5 m/min, a rewind rate of 120% for the high-pressure rolling mill, and a rejuvenation rate of 11% for the dryer. The increase in single-line production capacity can reduce investment costs, save plant floor space, and reduce energy, materials and labor consumption in production operations. It is estimated that the 80,000-ton production line developed this time will reduce the investment in plant and equipment by 20% compared with the production capacity of two 40,000-ton production lines. The labor and energy consumption will be reduced by 30% and the economic benefits will be considerable. There are many innovative features in the dryer design and manufacturing process. Among them, the cotton opener of the wet opener adopts the form of a Maurel spike to improve the effect of opening the cotton; the feeder increases the support bar on the rotating frame of the curtain to solve the problem of the curtain swinging; the top of the feeder is increased. The design of pressure relief device ensures the smoothness of the cotton in the machine; the ribs of the dryer plate adopt the design of the reel pipe, the panel adopts the articulation form, and the overall strength is ensured; the heating zone and normal temperature zone of the dryer frame adopt two-layer arrangement. Designed to avoid thermal expansion and contraction; sealed on both sides of the curtain, air seal and butterfly plate double seal, to avoid flying on both sides; heat insulation door is sealed with spring steel plate and frame, inlet and exhaust air use single zone control design, easy Adjust the matching of the inlet and exhaust air of the drying room; the frequency conversion of the exhaust fan regulates the energy consumption of the dryer; the open structure of the opener cotton roller adopts a new structure to enhance the stability of the roller; fine open cotton adopts microwave detection, Improve the control accuracy; fine open cotton installed at the outlet with a wind pressure sensor to ensure stable operation. On the leading products such as polyester staple fiber equipment and viscose fiber equipment, Hengtian Heavy Industries has pioneered the development of 150 tons and 200 tons of polyester staple fiber complete sets of equipment, and achieved a successful start. As for viscose fiber, Hengtian Heavy Industry’s leading products accounted for more than 90% of the domestic market and were exported to the Austrian Lenzing Group and India’s Bora Group. The successful development of an annual production capacity of 80,000 tons of viscose staple fiber post-processing production line indicates that Hengtian Heavy Industries viscose staple fiber post-processing equipment has reached the world's leading technical level, and will further consolidate the Hengtian Heavy Industry's viscose fiber equipment. Technical advantages to promote the upgrading of viscose fiber industry at home and abroad.
