[0002] As an important part in the production of polyester filament, ring blowing cooling plays a huge supporting role in the development of the chemical fiber industry. However, when it comes to fine-denier profiled polyester fiber, with the increasing complexity and particularity of the profiled shape of the fiber cross-section, especially the increasingly complex profiled antennae and supports of the fiber, the traditional ring blowing cooling equipment can no longer meet the production needs. The traditional ring blowing cooling device adopts a hollow cylindrical hollow-out structure filter element, and the filament bundle passes through the inside of the filter element, and the cooling air is blown into the filter element from the outside to cool the filament bundle. However, this structure is prone to cause the turbulent backflow of the ring blowing cooling air in the filter element cavity after cooling the filament bundle, and the combined downward blowing out of the filter element, which not only causes the filament bundle to shake and fight with each other, uneven cooling of the filament bundle, but also causes unnecessary waste. Therefore, it is urgently necessary to optimize the structure of the traditional ring blowing cooling equipment, provide a blowing and suction balanced cooling device for a double-cylindrical filter element of fine-denier profiled polyester fiber, and carry out suction and recovery treatment on the ring blowing cooling air after cooling the filament bundle, so as to ensure the uniformity and stability of the filament bundle cooling, reduce the shaking interference of the filament bundle, improve the physical properties and dyeing uniformity of the filament bundle, reduce energy waste, and reduce production costs.

For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium.

[0024] Such as Figure 1As shown in the figure, a balanced blowing and suction cooling device for a fine denier profiled polyester fiber double-cylindrical filter element includes a double-cylindrical blowing and suction balanced filter element 1. The double-cylindrical blowing and suction balanced filter element includes an outer cylindrical filter element 101 and an inner cylindrical filter element 102. The inner cylindrical filter element is coaxially arranged inside the outer cylindrical filter element, and there is a gap between them. The tow to be cooled by annular blowing passes through the gap between the inner and outer cylindrical filter elements. Ventilation holes 2 are evenly arranged on the side walls of the outer cylindrical filter element and the inner cylindrical filter element. Cooling air enters from the outside of the outer cylindrical filter element and passes through the ventilation holes on the outer cylindrical filter element to cool the tow. One side of the inner cylindrical filter element is connected with a suction pipe 3. One end of the suction pipe is communicated with the inside of the inner cylindrical filter element, and the other end passes through the outer cylindrical filter element and is connected with a suction fan 4. The excess cooling air after the tow is cooled reaches the inside of the inner filter element through the ventilation holes of the inner cylindrical filter element and is adsorbed and discharged by the suction pipe under the action of the suction fan for recycling and reuse. In order to ensure the suction balance of the cooling air, the number of suction pipes is two, and the two suction pipes are respectively connected to one side of the axial two ends of the inner cylindrical filter element to avoid affecting the stability and uniformity of the tow cooling.

[0025] Combined with Figure 2 and Figure 3 As shown in the figure, two inner windless areas 10201 are symmetrically arranged at the axial two ends of the inner cylindrical filter element. Between the two inner windless areas is an inner air outlet area 10202. The ventilation holes on the inner cylindrical filter element are evenly arranged in the inner air outlet area. The two suction pipes are respectively connected to the two inner windless areas. Two outer windless areas 10101 and two outer air outlet areas 10102 are symmetrically arranged on the outer cylindrical filter element along the central axis. The two outer air outlet areas and the two outer windless areas are alternately connected end to end along the circumferential direction. The ventilation holes on the outer cylindrical filter element are evenly arranged in the two outer air outlet areas. The connection part of the suction pipe and the outer cylindrical filter element is located in one of the outer windless areas. The aperture of the ventilation hole on the outer cylindrical filter element is 10μm, and the aperture of the ventilation hole on the inner cylindrical filter element is 20μm. The air outlet areas and windless areas on the inner and outer cylindrical filter elements are symmetrically arranged respectively to ensure the uniformity and stability of the tow cooling, and at the same time facilitate the installation of the connecting pipe to ensure that it will not affect the tow cooling. The suction pipe is detachably connected to the inner filter element and the outer filter element by a plug connector 5. The suction pipe can be spliced in sections, and the adjacent two pipe bodies are quickly plugged by the plug connector, which is convenient for disassembly and assembly and more convenient to use. Plug holes 6 for installing the plug connector are arranged on both the inner cylindrical filter element and the outer cylindrical filter element. The plug connector is composed of two plugging monomers connected by threads, and an elastic washer is arranged on the inner wall of the end part, which is convenient for the quick installation and fixation of the suction pipe.

[0026] During the use of the utility model, in order to cool multiple groups of fiber bundles, the number of double-cylindrical blow-suction balanced filters is multiple groups, and they are evenly spaced in the cooling air box 7 located outside it. The cooling air in the cooling air box cools the fiber bundles inside each double-cylindrical blow-suction balanced filter. Each double-cylindrical blow-suction balanced filter is connected to a manifold 8 located at the bottom of the cooling air box through a suction pipe. The suction pipe and the cooling air box are also connected by a plug-in joint. The manifold is connected to a suction fan, which is convenient for the centralized recovery of cooling air and also ensures the stability and uniformity of the cooling process of each group of cooled fiber bundles, thereby improving the product performance.

[0027] The working principle of the utility model is as follows:

[0028] As Figures 1 to 4 shown, the fiber bundle axially passes through the gap between the outer cylindrical filter element 101 and the inner cylindrical filter element 102 and is symmetrically distributed in the air outlet areas on both sides. The cooling air in the cooling air box 7 enters the gap through the ventilation holes 2 in the outer air outlet area 10101 outside the outer cylindrical filter element 101 to cool the fiber bundle. The excess cooling air enters the inner cylindrical filter element 102 through the ventilation holes 2 in the inner cylindrical filter element 102 and is discharged from the suction pipes 3 at the upper and lower ends under the action of the suction fan 4 for centralized recovery and convenient reuse.

[0029] The above shows and describes the basic principles, main features and advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
