Description

Technical Field

[0001] The utility model relates to the field of cotton wool collecting devices, in particular to a floating cotton wool collecting device for a four-roller fiberizing centrifuge. Background Art

[0002] The four-roller fiberizing centrifuge can be used to convert fibers into cotton, and the finished cotton products are discharged from the outlet. The outlet of the existing four-roller fiberizing centrifuge is tilted upward, and floating cotton wool will be generated during the discharge of cotton products. In order to prevent the cotton wool from polluting the surrounding working environment, a floating cotton wool wind adsorption device is set on the side of the cotton product outlet, which has the following two problems:

[0003] 1. The adsorption effect of floating cotton wool is not good. Some floating cotton wool continues to float upward after falling off the cotton product, and eventually falls to other working areas, causing work environment pollution problems;

[0036] The floating cotton wool collection device disclosed in Example 1 was tested for cotton wool adsorption effect. The test results showed that no cotton wool floated to other working environments during the continuous operation of the four-roller fiberizing centrifuge for 18 hours. The inclined section 4 and the vertical section 3 were tested, and no cotton wool was retained inside them. The filter screen 9 was tested, and no cotton wool remained on the surface of the filter screen 9, and good ventilation was achieved.

[0037] Example 2

[0038] The difference between this embodiment and embodiment 1 is that the inclination of the inclined section 4 is 45°. The floating cotton wool collection device disclosed in embodiment 2 was tested for its effectiveness. The test results showed that no cotton wool floated to other working environments during the continuous operation of the four-roller fiberizing centrifuge for 18 hours. The inclined section 4 and the vertical section 3 were tested, and no cotton wool was retained inside them. The filter screen 9 was tested, and no cotton wool remained on the surface of the filter screen 9, and good ventilation was achieved.

[0039] Comparative Example 1

[0040] The difference between this embodiment and embodiment 1 is that the inclination of the inclined section 4 is 30°. The floating cotton wool collection device disclosed in embodiment 2 was tested for its effectiveness. The test results showed that no cotton wool floated to other working environments during the continuous operation of the four-roller fiberizing centrifuge for 18 hours.
