Abstract

The invention relates to a device for continuously and rapidly defoaming high-viscosity fluid. The upper part of the device is a vacuum defoaming tank; a vacuum suction opening is arranged on the vacuum defoaming tank, and an umbrella-shaped piece is arranged in the vacuum defoaming tank; the upper part of the umbrella-shaped piece is narrower than the lower part and is connected with a feeding inlet; the position where the upper part of the umbrella-shaped piece is connected with the feeding inlet is provided with a slit and a slit adjusting device; the fluid of different viscosity and flow rate, which enters the vacuum defoaming tank, can form continuous films of uniform thickness on the umbrella-shaped piece by adjusting the width of the slit; the lower part of the device is a screw extruder which is provided with a motor and a driving device; the motor rotates to drive a screw to rotate so as to continuously output the material in the vacuum defoaming tank; in addition, a stirring device can be arranged in the vacuum defoaming tank according to the need, and the stirring device can be driven by the screw at the bottom or other driving force on the top of the vacuum defoaming tank. The device can be used for continuously and rapidly defoaming the high-viscosity fluid, particularly the high-viscosity fluid whose characteristic can change along with time, temperature and other factors.

Description

technical field [0001] The invention relates to a continuous and rapid defoaming device for high-viscosity fluid in the high polymer field. It is especially suitable for continuous and rapid defoaming in the production of high-viscosity fluids. Background technique [0002] In the spinning process of high-viscosity polymer solution, in order to improve fiber quality, reduce spinning breakage, and increase productivity, the polymer solution needs to be defoamed to remove small bubbles in the solution. The usual method is static Vacuum defoaming method and slit overflow defoaming method. [0003] For static defoaming, because the diffusion speed of bubbles in high-viscosity fluid is very slow, it takes a long time for bubbles to migrate from the middle and lower part of the solution to the surface under vacuum negative pressure, so the defoaming time is long, and for some high-viscosity polymers For example, the polymer stock solution used in the production of aramid fibers ...
