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
The present invention relates to a kind of spandex production equipment, relate in particular to a kind of spandex defoaming device.
Background technology
At present, the general defoaming device of spandex production comprises tapered inner core; Its lower end is provided with liquid outlet, and its top is provided with inlet, and the inlet lower end is connected with an annular part flow arrangement; The inwall of tapered inner core is pressed close in the outlet of annular part flow arrangement, and the inside of tapered inner core vacuumizes, during use; Spandex stoste is sent into annular part flow arrangement from inlet; The inwall that spandex stoste flows out the tapered inner core in edge, back from the outlet of annular part flow arrangement flows down, and handles thereby carry out deaeration, and the spandex stoste after the deaeration flows out from liquid outlet.
Yet; Because spandex stoste is directly to flow down along the inwall of tapered inner core to carry out deaeration; The deaeration area that its spandex stoste is flowed through is less, and when spandex production output increased, a large amount of spandex stoste will be carried out continuous deaeration and handled; Limited deaeration area will cause the bubble in the spandex stoste to fail all to purify, thereby can influence the fiber number and the intensity of spandex silk.
Summary of the invention
The object of the present invention is to provide the big spandex defoaming device of a kind of deaeration area, improve the deaeration effect of spandex defoaming device when carrying out the spandex deaeration continuously in a large number.
For achieving the above object; The invention provides a kind of spandex defoaming device, comprise tapered inner core, its upper end is equipped with inlet; The lower end of said inlet is connected with several equally distributed separating tubes through cylindrical cavity; The below of said separating tube is equipped with the baffling tube, and said baffling tube is had on the conical butt cavity vertical direction of upper and lower opening by several and connects and composes, and the separating tube outlet of each said separating tube is corresponding with the inner wall position at said baffling tube top.
Spandex defoaming device of the present invention, said conical butt cavity has six, and the wide base of every said conical butt cavity is fixed on the inwall of said tapered inner core.
Spandex defoaming device of the present invention, said baffling tube top is equipped with gripper shoe, and the bottom of said cylindrical cavity is positioned on the said gripper shoe, and each said separating tube is fixed on the said gripper shoe, and said gripper shoe is stretched out in each separating tube outlet.
Spandex defoaming device of the present invention, said tapered inner tank theca is provided with the insulation jacket of cooperation.
Spandex defoaming device of the present invention; Lower end at inlet is connected with several separating tubes through cylindrical cavity, and the below of separating tube is equipped with the baffling tube, and the baffling tube is had on the conical butt cavity vertical direction of upper and lower opening by several and connects and composes; The separating tube outlet of each separating tube is corresponding with the inner wall position at baffling tube top; During use spandex stoste is injected from inlet, spandex stoste flows on the baffling tube through cylindrical cavity and separating tube successively, flows out after turning back repeatedly along the baffling tube then; Thereby increased the deaeration area of spandex stoste; Improved the effect of spandex deaeration, handled, still can guarantee the effect of good deaeration even will carry out a large amount of continuously spandex stoste deaerations.

The specific embodiment
Be described in detail below in conjunction with the accompanying drawing specific embodiments of the invention:
With reference to shown in Figure 1; The spandex defoaming device of present embodiment comprises tapered inner core 1; Its upper/lower terminal is separately installed with inlet 2 and liquid outlet 7, the import welding of the lower end of inlet 2 and cylindrical cavity 3, and four equally distributed outlets of cylindrical cavity 3 are welded with a separating tube 4 respectively; Gripper shoe 8 on the inwall that is fixed on tapered inner core 1 is installed on the lower horizontal direction of cylindrical cavity 3; The bottom of cylindrical cavity 3 is positioned on the gripper shoe 8, and each separating tube 4 is fixed on the gripper shoe 8, and each separating tube outlet 4a stretches out gripper shoe 8; Gripper shoe 8 belows are equipped with baffling tube 5; This baffling tube 5 constitutes by welding on six conical butt cavity vertical directions with upper and lower opening, and the wide base of each conical butt cavity is weldingly fixed on the inwall of tapered inner core 1, and 4a is corresponding with the inner wall position at baffling tube 5 tops for the outlet of the separating tube of each separating tube 4.In order to increase the heat-insulating property of spandex defoaming device, lay the insulation jacket 6 of cooperation on tapered inner core 1 outer wall.During use, spandex stoste is injected from inlet 2, spandex stoste flows on the baffling tube 5 through cylindrical cavity 3 and separating tube 4 successively, turns back repeatedly six times after liquid outlet 7 flows out along baffling tube 5 then.
Above embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that the common engineers and technicians in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
