Abstract

The utility model relates to the field of carbon fiber preparation devices, in particular to a coagulating bath tank. The mixing-enhanced fiber forming coagulating bath tank comprises a bath tank body. A bath liquid recovery opening is formed in the position, close to a strand inlet, of the side wall of the bath tank body. A bath liquid compensation opening is formed in the position, close to a strand outlet, of the side wall of the bath tank body. A strand guide turning roller is arranged in the bath tank body. The bottom face inside the bath tank body is provided with a plurality of stirring blades. A motor is arranged outside the bath tank body and drives the stirring blades through a transmission mechanism. The stirring blades are evenly distributed at the bottom of the mixing-enhanced fiber forming coagulating bath tank, bath liquid in the bath tank is continuous neutralized through rotation of the stirring blades, fluctuations of temperature and concentration of the coagulating bath liquid are reduced, the required size of the coagulating bath tank can be decreased by 10%, arrangement cost of a production line is reduced, and production cost is reduced.

Description

Strengthen the fiberizing coagulating tank mixing

Technical field

The utility model relates to carbon fiber preparation facilities field, relates in particular to a kind of coagulating tank.

Background technology

LYOCELL fiber is that international artificial fibre and the synthetic fiber standardization BISFA of office are the determined generic name of new fiber that organic solvent spin processes makes.LYOCELL fiber production process belongs to environmentally friendly machine, and discarded LYOCELL fiber can decompose completely in earth, greatly reduces injury and pollution to environment.

In existing Lyocell spinning, mostly adopt the dry method that squirts, spinning solution (the NMMO solution of containing cellulose) by metering, filter, extruding spray silk becomes a stoste thread to enter coagulating tank to carry out coagulating bath, stoste thread is in coagulating bath, surface concentrated phase solvent and water are constantly diffused in coagulation bath, and stoste thread surface solidify to form as-spun fibre gradually; In order to ensure the uniformity of fiberizing quality, strand body lotion around need to keep the constant of temperature and concentration as far as possible;

Because the strand temperature of spinnerets ejection all can be higher than normal temperature, and the concentration of spinning solution is higher than coagulation bath concentration, so the bath temperature in coagulating tank and concentration all can constantly change, in order to ensure the quality of fiberizing, can only adopt the coagulating bath circulation system of large bath raio to ensure coagulation bath concentration Deviation Control; Taking existing technique as example, if body lotion fluctuation of concentration be controlled at ± 0.1%, bring solvent in coagulating bath into as 5m taking strand ³/ h calculates, and in order to keep coagulating bath fluctuation of concentration, need to configure 5000m ³coagulating tank, and configure the circulating pump of respective capabilities, therefore body lotion reclaims the investment of the required energy resource consumption of circulation and infrastructure device and takes up an area all considerable.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of fiberizing coagulating tank that strengthens mixing, uniform several stirring vanes that is provided with in bottom of this bath, utilize the rotation of stirring vane that the body lotion in bath is constantly neutralized, temperature and the fluctuation of concentration of coagulation bath are reduced, reduce and produced the cost of layout of line, and then reduced production cost.

The utility model is achieved in that a kind of fiberizing coagulating tank that strengthens mixing, comprise bath body, on the sidewall of bath body near strand import, be provided with body lotion and reclaim mouth, on the sidewall of bath body near strand outlet, be provided with body lotion and supplement mouth, in bath body, be provided with seal wire slewing rollers, described bath is provided with several stirring vanes on intrinsic bottom surface, and bath body is equipped with motor outward, and described motor drives stirring vane by transmission mechanism.

Described stirring vane has four, and four stirring vane squarelys are distributed in bath body.

Described body lotion reclaims mouthful sidewall that is arranged on a bath body bottom.

Described body lotion supplements a mouthful top side wall that is arranged on bath body.

The utility model strengthens uniform several stirring vanes that is provided with in bottom of the fiberizing coagulating tank mixing, utilize the rotation of stirring vane that the body lotion in bath is constantly neutralized, temperature and the fluctuation of concentration of coagulation bath are reduced, can reduce the volume demand of coagulating tank 10%, reduce and produced the cost of layout of line, and then reduced production cost.

Brief description of the drawings

Fig. 1 is that the utility model strengthens the main TV structure schematic diagram of fiberizing coagulating tank mixing;

Fig. 2 is schematic top plan view of the present utility model.

In figure: 1 bath body, 2 strands, 3 body lotions reclaim mouth, 4 body lotions supplement mouth, 5 stirring vanes, 6 motors, 7 seal wire slewing rollers.

Detailed description of the invention

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.

Embodiment 1

As shown in Figure 1, a kind of fiberizing coagulating tank that strengthens mixing, comprise bath body 1, on the sidewall of bath body 1 near strand 2 imports, be provided with body lotion and reclaim mouth 3, on the sidewall that bath body 1 exports near strand 2, be provided with body lotion and supplement mouth 4, in bath body 1, be provided with seal wire slewing rollers 7, strand 2 enters into the concentrated phase solution that can bring high temperature after coagulating tank into, so need recycle unit that body lotion unnecessary in coagulating tank is reclaimed to mouthful 3 discharges from body lotion, and replenish dilute phase body lotion for supplementary mouthful 4 from body lotion;

In the present embodiment, in order to promote the mixing of body lotion, ensure the uniformity of body lotion in bath, be provided with several stirring vanes 5 on the bottom surface in described bath body 1, bath body 1 is outer is equipped with motor 6, and described motor 6 drives stirring vane 5 by transmission mechanism.

In the present embodiment, as described in Figure 2, described stirring vane 5 has four, and four stirring vane 5 squarelys are distributed in bath body 1.

For the ease of to the supplementing of body lotion, and ensure that supplementary body lotion can spread fully and circulate, in the utility model, described body lotion reclaims mouthfuls 3 and is arranged on bottom the sidewall of bath body 1; Described body lotion is arranged on the top side wall of bath body 1 for supplementary mouthful 4.
