Description

Technical Field

[0001] The utility model relates to the field of chemical fiber production, in particular to a chemical fiber ring blowing device. Background Art

[0002] Chemical fiber is a fiber with textile properties made from natural polymer compounds or synthetic polymer compounds, through the processes of preparing spinning solution, spinning and post-treatment. The spinning and post-treatment processes are usually heating the spinning solution, drawing and solidification. Drawing is roughly divided into the flow of spinning solution in the spinneret, the transformation from the shear flow in the spinneret to the tensile flow on the spinning line, and the uniaxial tensile flow. Solidification is usually air-cooled molding. The chemical fiber ring blowing equipment is connected to the outlet hole at the lower end of the spinning box to air-cool the chemical fiber drawn. Usually, there is only one set of outlet holes at the lower end of a spinning box, and the chemical fiber ring blowing equipment is also a single-row cooling device. For a spinning manifold with two sets of silk outlet holes, due to the distance between the two sets of silk outlet holes, the width of the ground groove and the thickness of the single-row chemical fiber ring blowing equipment, the two single-row chemical fiber ring blowing equipment cannot be connected back to back and side by side to the silk outlet holes at the lower end of the spinning manifold. In this way, only one set of silk outlet holes can be used, which leads to problems such as large plant space occupation, reduced equipment utilization and reduced production efficiency. As disclosed in Chinese utility model patent CN219490254U, an industrial chemical filament ring blowing cooling device includes a mounting frame, a cooling unit and a lifting drive device, wherein the cooling unit is movably mounted on the middle and lower part of the mounting frame; the cooling unit includes a bellows, a straight air duct, a bottom air duct and a square air duct which are connected in sequence, the bellows is arranged on the right side inside the mounting frame, and the bottom port of the bellows is connected to the wind source device; the left port of the bellows is connected to the right port of the straight air duct, a porous plate I is arranged in the bellows, the left port of the straight air duct is connected to the right port of the bottom air duct, a porous plate II is arranged between the left port of the straight air duct and the right port of the bottom air duct, the upper port of the bottom air duct is connected to the lower port of the square air duct, a porous plate III is arranged between the bottom air duct and the square air duct, and a wind tube is arranged inside the square air duct; the lifting drive device is mounted on the mounting frame and connected to the cooling unit. This patent has the advantages of good rectification effect and high production quality, but it is limited by the volume and thickness of the patent itself, and it cannot be connected back to back and side by side to the two groups of outlet holes at the lower end of the spinning box. Another example is a ring-blowing cooling device in chemical fiber production disclosed in Chinese utility model patent CN211256165U, which includes a spinneret, a ring-blowing bellows, and a wire mesh cylinder. The spinneret and the ring-blowing bellows are arranged on a frame, a wire mesh cylinder is arranged inside the ring-blowing bellows, and an air inlet pipe is arranged on the ring-blowing bellows. The wind entering the ring-blowing bellows passes through the wire mesh cylinder, the wire mesh cylinder is located directly below the spinneret, and the chemical fiber output from the spinneret passes through the wire mesh cylinder. An extended wind cylinder is connected to the lower end of the wire mesh cylinder, and the extended wind cylinder includes an inclined transition section at the upper end and a straight section at the lower end. The inclined transition section of the extended wind cylinder is connected to the lower end of the wire mesh cylinder. This patent also cannot be connected back to back and side by side to the two sets of wire outlet holes at the lower end of the spinning box due to its own volume, thickness and other issues.
