Accompanying drawing explanation
Fig. 1 is the sectional structure chart of a kind of acrylic fibre wet spinning coagulating tank of the present utility model.
Detailed description of the invention
Below in conjunction with Fig. 1 to a kind of acrylic fibre wet spinning coagulating tank of the present utility model, be described further:
A kind of acrylic fibre wet spinning coagulating tank of the present utility model is made up of the preposition groove 1 of solidification liquid, cell body 2 and circulation line 3.
The preposition groove 1 of solidification liquid is fixed with cell body 2, the cell wall 12 that existence one is shared between the two, cell wall 12 is provided with multiple inlet 13 towards the one side of the preposition groove of solidification liquid 1, one side towards cell body 2 is provided with the shower nozzle 14 matched with inlet 13, and the preposition groove 1 of solidification liquid is communicated with shower nozzle 14 by inlet 13 with cell body 2.Above-mentioned cell wall 12 has the recessed cambered surface to the preposition groove 1 of solidification liquid, and this cambered surface avoids dead angle, can reduce the fluctuation of concentration of coagulation bath.
Liquid injection pipe 4 and exhaust outlet 5 is provided with at the top of the preposition groove 1 of solidification liquid, and be provided with vertical deflection plate 6 therein, the bottom of deflection plate 6 and the preposition groove of solidification liquid 1 fix and and have overfall 7 between the top of the preposition groove 1 of solidification liquid, Figure 1 shows that example, preposition for solidification liquid groove 1 is divided into two chambers in left and right by deflection plate 6, wherein liquid injection pipe 4 is positioned at the top of left chamber, and exhaust outlet 5 is positioned at the top of right chamber.Deflection plate 6 can extend the stroke of coagulation bath movement, right chamber is entered after coagulation bath moves to overfall 7, can by with gas stay top, when gas build to a certain extent time, can open exhaust outlet 5 and carry out gas purging, the production of bubble to acrylic fiber that effectively prevent coagulation bath existence impacts.
Dividing plate 8 is provided with in cell body 2, on this dividing plate 8, hollow out has multiple open-work 9, and the slewing rollers 10 of dividing plate 8 lower end arrange with the interlaced undulate of deflector roll 11 be located in cell body 2, as shown in Figure 1, cell body 2 is divided into two chambers in left and right by dividing plate 8, and the spinning head 19 inside containing spinning solution is deep into the below of left chamber, after the fiber that its spinning solution sprayed is frozen in coagulation bath, turn to through slewing rollers 10 and passing through other deflector rolls successively, forming a corrugated curve.Left chamber in cell body 2 can form a relatively independent space, in this space the concentration of coagulation bath and temperature fluctuation all relatively little, so spinning head tentatively coagulates silk herein.
The bottom of one end access cell body 2 of circulation line 3 is also communicated with, is provided with circulation valve 16, filtering cabin 17 and drawing liquid pump 18 successively in the middle of it and the other end access preposition groove 1 of solidification liquid being communicated with, and circulation line 3 is communicated with the left chamber of the preposition groove 1 of solidification liquid.
In order to ensure that the concentration of coagulation bath mixes, in the preposition groove 1 of solidification liquid, be provided with paddle 15.The coagulation bath that the coagulation bath of interpolation new in preposition for solidification liquid groove 1 and circulation and stress come can carry out fully stirring and Homogeneous phase mixing by paddle 15, eliminate concentration difference, and due to after being full of liquid in the preposition groove 1 of solidification liquid and coagulation bath just can spray in cell body 2 by the state lower nozzle 14 sentencing certain pressure, the concentration of coagulation bath that now no matter the shower nozzle 14 of that position sprays is consistent, effectively reduces the fluctuation of concentration of coagulation bath.
Reduce the fluctuation of concentration of coagulation bath in order to avoid dead angle, cell body 2 inner bottom part tilts, be lowest part near solidification liquid preposition groove 1 place.
In the outside of cell body 2, be positioned on certain altitude, overflow pipe can be communicated with, this overflow pipe can limit the total amount of coagulation bath in cell body 2, when the coagulation bath being arranged in cell body 2 reach a certain height, can be flowed out by overflow pipe, overflow pipe can connect circulation line 3 or emission treatment pipeline, the coagulation bath being entered circulation line 3 by overflow pipe can recycling, and the coagulation bath being entered emission treatment pipeline by overflow pipe can be discharged process.
The preposition groove 1 of solidification liquid and cell body 2 should be made up of insulation material, are used for being incubated coagulation bath, prevent unnecessary temperature fluctuation.
A kind of acrylic fibre wet spinning coagulating tank of the present utility model, its concrete using method is as follows:
Liquid injection pipe 4 is used in the preposition groove of solidification liquid 1, to inject coagulation bath until the preposition groove 1 of solidification liquid fills, after this continue to inject coagulation bath, then in the preposition groove 1 of solidification liquid, pressure increases gradually, the shower nozzle 14 that cell wall 12 is provided with can be ejected in cell body 2 coagulation bath from the preposition groove 1 of solidification liquid, the amount being positioned at the coagulation bath of cell body 2 is like this on the increase, continuous interpolation coagulation bath is to not having all deflector rolls 11 completely, spinning head 19 starts to spray Polyacrylonitrile Fiber Spinning Solution thus is frozen into acrylic fiber afterwards, concretionary acrylic fiber is derived by deflector roll 11, access in next equipment.
In the process that acrylic fiber generates, this acrylic fibre wet spinning coagulating tank can also be recycled coagulation bath by the circulation line 3 of peripheral hardware, in cell body 2, multiple concentration detection apparatus can be installed, be used for detecting the coagulation bath concentration of diverse location in cell body 2, when coagulation bath concentration lower than during certain value or reach other impose a condition time, start the drawing liquid pump 18 on circulation line 3, start to extract coagulation bath bottom cell body 2 and by the coagulation bath of extraction by being delivered in the preposition groove 1 of solidification liquid after filtering cabin 17 again, and at solidification liquid preposition groove 1, concentration detection apparatus also can be installed, can the slightly low or slightly high coagulation bath of concentration of interpolation concentration be carried out according to the concentration of coagulation bath in the preposition groove of current solidification liquid 1 and reach desired concn after paddle uniform stirring.
