Problems solved by technology

[0003] However, since the spandex stock solution flows down directly along the inner wall of the cone-shaped inner cylinder for defoaming, the defoaming area through which the spandex stock solution flows is relatively small. The limited defoaming area will cause the bubbles in the spandex stock solution to not be completely removed, which will affect the fineness and strength of the spandex yarn

Abstract

The invention discloses a polyurethane deaeration device, which comprises a conical internal cylinder, wherein the upper end of the internal cylinder is provided with a liquid inlet; the lower end of the liquid inlet is connected with a plurality of evenly distributed liquid distribution pipes by a cylindrical cavity; baffle tubes are arranged below the liquid distribution pipes; each baffle tubeis formed by vertically connecting a plurality of round-table cavities, wherein each round-table cavity is provided with an upper opening and a lower opening; and the liquid distribution outlet of each liquid distribution pipe is opposite to the inner wall at the top of the baffle tube. The polyurethane deaeration device provided by the invention has the advantages of increasing the deaeration area of polyurethane basic solution, improving the effect of polyurethane deaeration.

Description

technical field [0001] The invention relates to spandex production equipment, in particular to a spandex defoaming device. Background technique [0002] At present, the general defoaming device for spandex production includes a cone-shaped inner cylinder with a liquid outlet at the lower end and a liquid inlet at the upper part. The lower end of the liquid inlet is connected with an annular flow device. The inner wall of the inner cylinder is vacuumed inside the cone-shaped inner cylinder. When in use, the spandex stock solution is sent from the liquid inlet to the annular splitter device. The spandex stock solution flows out from the outlet of the annular splitter device and flows down the inner wall of the cone-shaped inner barrel, thereby Carry out defoaming treatment, and the spandex stock solution after defoaming flows out from the liquid outlet. [0003] However, since the spandex stock solution flows down directly along the inner wall of the cone-shaped inner cylinde...
