Description
Technical field
The utility model relates to lyocell fiber production equipment technical field, is specifically related to a kind of lyocell fiber tow water washing device.
Background technology
At present, Lyoell fiber is a kind of novel regenerated celulose fibre, and it cellulose pulp is directly dissolved in nontoxic N-methylmorpholine-N-oxide (NMMO) aqueous solution form cellulose solution, is then obtained by dry-wet spinning.Compare with traditional regenerated celulose fibre and viscose, Lyocell fiber have strength and modulus higher, extend the Some features such as little, good stability of the dimension, heat resistance are good, production technology is environmentally friendly, be subject to pursuing of people.
Because solvent NMMO price is higher, so be the key determining production cost to the recovery of solvent, and the washing of tow is the important step improving the rate of recovery
But in present actual production, existing tow water washing device structure is very simple, only comprises several pressure roller, and accumulator tank is set below pressure roller solvent is reclaimed.This causes tow water washing effect very poor, not only tow is stained with a large amount of solvent NMMO and reduces product quality, also makes solvent NMMO reclaim difficulty, improves production cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lyocell fiber tow water washing device, and its cleaning residual quantity is little, and eluate concentration is high, improves the quality of products, and avoids the waste of solvent, thus eliminates defect in above-mentioned background technology.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of Lyocell fiber tow water washing device, comprises some groups in order to draw with the traction unit of squeezing tow, clean the washing unit of tow and collect the water collecting unit of eluent,
Described traction unit of often organizing comprises the upper drive roll and lower drive roll arranged up and down, described upper drive roll and lower drive roll each other alternate, distribute in broken line, and the upper drive roll often organizing traction unit least significant end is configured with the driven voller fitted tightly with it, in order to squeeze tow moisture
Described washing unit comprises the overflow tank of wedge type, and described overflow tank is installed on the below of described upper drive roll, its ramped side walls parallel press close to tow, the ramped side walls of described overflow tank offers overfall, the opening direction of described overfall down, in order to provide rinse water and pilot flow direction
Described water collecting unit comprises the water collecting groove be arranged at below described often group traction unit, in order to collect eluent.
As a kind of technical scheme of optimization, described traction unit has 3-6 group, and mutually connects.
As a kind of technical scheme of optimization, described traction unit of often organizing comprises 3-6 to the upper drive roll cooperatively interacted and lower drive roll.
As a kind of technical scheme of optimization, described water collecting groove is connected to the overflow tank of its one group of traction unit in upstream, thus reaches raising eluate concentration, the object of saving water resource.
The utility model operationally, the motion of overflow water rooved face pressed close to by tow under the traction of drive roll, overflow water trough inner water flows down from spilling suitable for reading along outer surface, tow is rinsed, at water washing device afterbody drive roll and driven voller, tow is squeezed, entering next water washing device and repeat washing, by repeatedly squeezing washing, reaching better water washing effect.Current flow into the overflow tank of a upper device by the water collecting groove of next water washing device, and the eluting water of next device, as the rinse water of a upper device, decreases the consumption of water, improve eluate concentration.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
Traction unit of often organizing of the present utility model comprises the upper drive roll and lower drive roll arranged up and down, described upper drive roll is alternate each other with lower drive roll, distribute in broken line, and the upper drive roll often organizing traction unit least significant end is configured with the driven voller fitted tightly with it, in order to squeeze tow moisture, described washing unit comprises the overflow tank of wedge type, and described overflow tank is installed on the below of described upper drive roll, its ramped side walls parallel press close to tow, the ramped side walls of described overflow tank offers overfall, the opening direction of described overfall down, in order to provide rinse water and pilot flow direction.Based on this structure, tow can be pressed close to in the ramped side walls of overflow tank, when the water of overflow tank is discharged from overfall, the cleaning of distance can be grown tow, thus efficient washing can be realized, meet lyocell fiber cleaning demand completely, and the NMMO effectively reclaimed in tow, reduce the loss of NMMO, save space and water, improve the concentration of NMMO in eluent, facilitate subsequent concentration technique.
Water collecting groove of the present utility model is connected to the overflow tank of its one group of traction unit in upstream.Based on this structure, rinse water can be carried out recycle, reach raising eluate concentration, the object of saving water resource
In sum, the utility model can have the NMMO in cleaning tow, reaches the object of NMMO recycle, and this device saves space and water, facilitates subsequent technique.
