Description
Technical field
The present invention relates to the viscose staple fibre technical field, be specifically related to a kind of jumbo viscose staple fibre production line for refining.
Background technology
Since phase early 1960s, the capacity of equipment of viscose staple fibre production line has experienced from the process of annual production 5000 t, 10,000 t, 20,000 to 30,000 t, at present the highest 4.5 ten thousand t that reached.Jumbo viscose staple fibre production line has been saved the up-front investment of factory building, equipment, public work etc., greatly reduces the specific energy consumption of production process, has improved labor productivity, has reduced production cost, makes business administration more simple and reliable.At present, large capacity viscose staple fibre production line has market prospects and demand widely, and many short rayon fibers enterprise is all carrying out old line transformation and enlarging, produces the main demand that the above viscose staple fibre production equipment of 20,000 t becomes each enterprise per year.
As document " LH151 series viscose staple fiber scouring machine and select ", come from " textile machine ", the 3rd phase in 2009, structure and the performance of LH151 type scouring machine are disclosed, and the problem should be noted that while having proposed this series scouring machine is selected.The document discloses production line and the production technology thereof of refiner, the annual approximately output of 4.3 ten thousand t of the refiner maximum production that heap(ed) capacity is 3.2 meters of fabric widths.But this production line is not suitable for larger fabric width, the output of annual 100000 t, if surpass this amplitude, the fault rate of equipment can be significantly improved, and the quality of product is also had to larger impact.
Summary of the invention
The present invention, in order to meet the output of annual 100000 t, provides a kind of jumbo viscose staple fibre production line for refining.This viscose staple fibre rectification systems production capacity is strong, stable, and automaticity is high, and product quality is secure.
For achieving the above object, the present invention adopts following technical scheme:
Jumbo viscose staple fibre production line for refining, refiner used comprises refining section, the section of oiling, and it is characterized in that: the fabric width of refiner is 4000mm, described refining section is divided 13 ~ 18 process island, the section of oiling minute 2 process island, single head of district 2500mm; Establish a pair of air bells removing roll between process island, before oiling together, rear twice high pressure mangle oils.The setting of three road padding machines, improved the effect of extracting of fiber, reduces and the machine moisture regain, improves drying efficiency, energy-saving and cost-reducing.
Single head of district 2500mm of the present invention than 2000mm in the past, can extend fiber 1.25 times of the wash times at each station under identical network speed, by increasing Station's length, effectively guarantees each technique erect-position wash time.
The present invention is in order to strengthen washing, than conventional washing many 2 to 3 process island, the washing of subregion of the present invention, desulfurization, bleaching are meticulousr, and, when process island is set, according to washing quality, change flexibly the function of adjacent erect-position, make it better to optimize washing quality.
Described refining section comprises: once wash 2 ~ 3 process island, 2 ~ 4 process island of desulfurization, 2 ~ 5 process island of secondary washing, bleach 1 ~ 3 process island, 2 ~ 5 process island of three washings.
Preferably, described refining section comprises: once wash 3 process island, 3 process island of desulfurization, 4 process island of secondary washing, bleach 2 process island, 3 process island of three washings.
