High-capacity viscose staple fiber post-treatment production line

Abstract

The invention aims at providing a high-capacity viscose staple fiber post-treatment production line in order to reach the annual yield of 100 thousand tons. The production line comprises a refining system and a drying system. A refiner in the refining system comprises a refining section and an oiling section. The high-capacity viscose staple fiber post-treatment production line is characterized in that the breadth of the refiner of the refining system is 4000mm, the refining section is divided into 13-18 process areas, the oiling section is divided into 2 process areas and the length of a single process area is 2500mm. The viscose staple fiber post-treatment production line comprises the refining system and the drying system, and has the advantages that the production capacity is strong, the operation stability is high, the automation level is high and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of viscose staple fiber, in particular to a large-capacity viscose staple fiber post-processing production line. Background technique [0002] Since the early 1960s, the equipment capacity of the viscose staple fiber production line has gone through the process of annual output from 5,000 tons, 10,000 tons, 20,000 tons to 30,000 tons, and the current maximum has reached 45,000 tons. The large-capacity viscose staple fiber production line saves the initial investment in plant, equipment, public works, etc., greatly reduces the unit energy consumption in the production process, improves labor productivity, reduces production costs, and makes enterprise management simpler and more reliable. At present, large-capacity viscose staple fiber production lines have broad market prospects and demands. Many viscose staple fiber enterprises are undergoing reconstruction and expansion of old lines. Viscose staple fiber p...

AI Technical Summary

Problems solved by technology

[0005] 1. Cyclone conveying is only suitable for the conveying of dry fibers. Because wet fibers have viscosity, it is not conducive to air conveying, so the equipment cannot be used normally for a long time

[0006] 2. The production capacity of cyclone conveying is small, and the scope of use is restricted

[0007] 3. Because the cyclone conveying requires a large air volume, and the use of drying waste heat has a small air volume, the air volume needs to be added to balance, and the newly added air volume needs to be heated, the equipment is complicated, and the energy consumption is increased

[0008] 4. The cyclone conveying cannot be effectively adjusted according to the production capacity, and the system cannot realize automatic adjustment
