Referring to fig. 3, a filter element 6 is arranged in the filter pipe 5, and the filter element 6 is made of filter cotton. When the air supply fan 3 (refer to fig. 1) supplies air towards the air supply pipeline 2 (refer to fig. 1), the air is filtered through the filter core 6, so that the air flow entering the spinning cooling cylinder 1 (refer to fig. 1) is cleaner, the possibility of impurities adhering to the surface of the strand silk is reduced, and the effect of improving the spinning forming quality is achieved.
Referring to fig. 3, an inner tube 7 is inserted into the filter tube 5, and a filter element 6 (see fig. 2) is bonded to the inner tube 7. The inner side wall of one end of the filter pipe 5 is fixedly connected with a resisting ring 52, and the resisting ring 52 is used for resisting the inner pipe 7. In order to reduce the obstruction of the gas flow by the retaining ring 52, the side of the retaining ring 52 facing away from the inner tube 7 is rounded. A locking ring 8 is also arranged in the filter pipe 5, and the locking ring 8 is positioned in one end of the inner pipe 7 far away from the stop ring 52. The inner diameters of the stopper ring 52, the inner tube 7 and the locking ring 8 are the same.

The cooperation of the sliding groove 54 and the sliding strip 71 reduces the possibility of the inner pipe 7 rotating in the filter pipe 5, thereby enabling the filter element 6 to perform the filtering work more stably. Meanwhile, the clamped ejection pressure spring 541 has an ejection effect, and when the inner tube 7 is locked in the filter tube 5, the ejection pressure spring 541 is pressed tightly and has resilience. When the inner tube 7 needs to be removed, when the locking ring 8 is screwed out, the elastic force of the ejection pressure spring 541 is released, so that the inner tube 7 is ejected for a certain distance, and the possibility that the inner tube 7 is difficult to be taken out from the filter tube 5 due to the wall sticking phenomenon of the sliding strip 71 and the sliding groove 54 is reduced.
The specific working process is as follows: the air supply fan 3 is started, air flow generated by the air supply fan 3 enters the air supply pipeline 2, before entering the spinning cooling cylinder 1, the air flow firstly passes through the filter pipe 5, the filter element 6 in the filter pipe 5 filters the air flow, impurities in the air flow are filtered, and then the air flow enters the spinning cooling cylinder 1 along the air supply pipeline 2, so that the air flow is conveyed.
When the filter element 6 is saturated, the air supply fan 3 is turned off, and then the worker removes the filter pipe 5. The worker unscrews the locking ring 8, the inner tube 7 is ejected out of the filtering tube 5 for a certain distance through the elasticity of the ejection pressure spring 541, and at the moment, the worker pulls out the inner tube 7. After the inner pipe 7 with the saturated filter element 6 is pulled out, a worker takes a new inner pipe 7 and inserts the new inner pipe 7 into the filter pipe 5, then screws the locking ring 8 again, locks the inner pipe 7 with the new filter element 6 in the filter pipe 5, finally installs the filter pipe 5 in the installation opening 21 again, starts the air supply fan 3 and continues air supply work.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
