Description

Technical Field

[0001] The present invention relates to the technical field of alginate fiber spinning, and particularly to a defoaming device for alginate fiber spinning solution. Background Art

[0002] The defoaming device for alginate fiber spinning solution is applied to the equipment for spinning of polymer natural materials. When dissolving natural polymer sodium alginate and preparing the spinning stock solution of sodium alginate, a large amount of air bubbles will be introduced during the stirring process. Before wet spinning, it is necessary to remove the air bubbles from the spinning solution. The existence of excessive air bubbles will cause the rupture of air bubbles when the spinning solution passes through the spinneret holes, resulting in the discontinuity of the as-spun fiber, making the entire spinning process unable to proceed smoothly.

[0003] In the prior art, the defoaming of alginate spinning solution is mostly carried out by static settling and vacuum defoaming. For the static settling scheme, the time consumption is long, and at the same time, sodium alginate will undergo hydrolysis when placed for a long time, and the performance of the final fiber will be affected due to the hydrolysis of alginic acid. For vacuum defoaming, to a certain extent, the defoaming efficiency can be improved, but due to the high viscosity of the spinning solution, it is difficult to remove all the air bubbles in the spinning solution, and the remaining air bubbles will still have an adverse effect on spinning.

[0004] The present invention aims to provide a defoaming device for spinning solution to cut and break the remaining air bubbles in the spinning solution, so that the spinning can proceed more smoothly. Summary of the Invention

[0005] The purpose of the present invention is to provide a defoaming device for alginate fiber spinning solution to solve the technical problem that spinning is difficult to be continuous due to the remaining air bubbles in the spinning solution in the prior art.

[0006] The concept of the present invention is to cut and break the air bubbles in the spinning solution through a puncture needle, so as to reduce the volume of the air bubbles. When the spinning solution enters the spinneret, it will not cause large-area fracture of the as-spun fiber due to the existence of large-volume air bubbles in the spinning solution, and the fiber bundle cannot be continuous, resulting in the inability to continue spinning. When small-volume air bubbles pass through the spinneret, due to the significant reduction in gas volume, the tiny air bubbles will cause a small amount of discontinuity of the as-spun fiber when passing through the spinneret, but will not cause large-area fracture of the as-spun fiber bundle. Therefore, the spinning process can still proceed smoothly.

[0007] To achieve the above object, the present invention provides the following technical solution: A defoaming device for alginate fiber spinning solution, including a defoaming machine, an inlet pipe and an outlet pipe are installed on the defoaming machine, a plurality of support frames for supporting the defoaming machine are fixed at the bottom of the defoaming machine, a partition member is fixed inside the defoaming machine, and the inside of the defoaming machine is divided into a feed chamber and a discharge chamber under the partitioning action of the partition member;

[0016] A guiding inclined surface is formed on one side of the through groove close to the feed chamber.

[0017] Furthermore, the driving assembly includes a driving shaft rotatably connected to the bottom of the defoaming machine, and one end of the driving shaft is fixed to one end of the mounting shaft;

[0018] An L-shaped plate is fixed to the lower end of the defoaming machine, one end of the mounting shaft is rotatably connected to the L-shaped plate, and a driving motor for driving the driving shaft is installed on the L-shaped plate.

[0019] In another embodiment, two sets of puncturing assemblies are provided, and the two sets of puncturing assemblies are respectively arranged corresponding to the two through grooves;

[0020] In the present invention, the spinning solution enters the discharge chamber through the through groove, and a puncturing assembly is arranged at the through groove. On the one hand, the puncturing assembly can puncture the air bubbles doped in the spinning solution, and on the other hand, the puncturing assembly can also filter the undissolved impurities in the spinning solution, making the spinning more smooth.

[0021] Furthermore, a sliding groove is further included on the partition member of the defoaming machine, and the sliding groove provides an installation space for the puncturing assembly;

[0022] Further, the puncturing assembly includes a bubble pricking needle, a strip-shaped plate, and a first pushing assembly;

[0025] Further, the strip-shaped plate is connected inside the sliding groove through a connecting assembly;

[0026] The connecting assembly includes a plurality of sleeves fixed inside the sliding groove. A sliding rod is slidably connected to each sleeve. One end of the sliding rod is fixed to the strip-shaped plate. A first spring is sleeved outside the sleeve.

[0027] Further, the first pushing assembly includes a fixing rod fixed on one side of the strip-shaped plate. The fixing rod is located above the bubble breaker. A connecting shaft is rotatably connected to the upper end of the bubble breaker. A mounting disc is fixed on the connecting shaft. A plurality of first protrusions for abutting and pushing one end of the fixing rod are annularly and arrayedly fixed on the outside of the mounting disc. The connecting shaft and the mounting shaft are connected through a transmission assembly.

A pumping assembly is provided on the delivery pipe for pumping and pressing the functional additive into the foam breaker.

[0032] Since adding a functional additive to the alginate spinning solution easily causes the degradation of the alginate spinning stock solution, therefore, in the solution of the present invention, it is directly added to the foam breaker. After the addition, the spinning solution will quickly enter the spinning screw for spinning, which can greatly reduce the degradation problem of sodium alginate.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

When the micro air bubbles pass through the spinneret plate, it will cause a small amount of discontinuity of the nascent fibers, but will not cause a large area breakage of the nascent fiber bundle. Therefore, the spinning process can still proceed smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
