A spinning annular blast apparatus

Abstract

The invention provides a spinning annular blast apparatus comprising a rectifying drum, a straight drum, an air inlet pipe, an air distributing box, an air evening net, flow guide air pipes, and an annular blast box. The air inlet pipe is connected with the air distributing box. The air evening net is arranged between the air distributing box and the annular blast box. The inner wall of the annular blast box is the rectifying drum. The outer wall of the annular blast box is provided with a plurality of flow guide air pipes. The air pressure in the rectifying drum is even, so that the blast balance in spinning cooling is guaranteed and the quality of the process section in the spinning process is improved.

Description

technical field [0001] The invention relates to the field of chemical fiber spinning production, in particular to a spinning circular blowing device. Background technique [0002] In the chemical fiber spinning production process, blowing cooling is generally used for melt spinning cooling, and the control of air volume and wind direction is the key to affecting spinning cooling. At present, manufacturers use a variety of blowing cooling devices, the most common ones are side blowing devices and annular blowing devices, and there are also many patents for ring blowing devices. The reason is that the air distribution in the upper and lower parts of the rectifier is uneven, and there is a large air pressure difference, which leads to uneven air volume entering the cylinder, thus affecting the cooling effect of melt spinning. Contents of the invention [0003] The invention provides a novel spinning circular blowing device. [0004] In order to achieve the above object, the...

Problems solved by technology

At present, manufacturers use a variety of blowing cooling devices, the most common are side blowing devices and annular blowing devices, and there are also many patents for ring blowing devices. These ring blowing devices still have certain deficiencies in controlling the wind direction and air volume, especially The air distribution in the upper and lower parts of the rectifier is uneven, and there is a large air pressure difference, which leads to uneven air volume entering the cylinder, thus affecting the cooling effect of melt spinning
