Problems solved by technology

[0003] A disadvantage of the thus disclosed embodiment is that high wear occurs on the feed rollers and the screen drum, since in order to completely transport the fibrous material held on the screen drum by the feed rollers, the scrapers of the feed rollers must scraping above the surface of the drum
As a result of this wear, the stripping becomes worse and the fibrous material is no longer completely removed from the screen drum

Embodiment Construction

[0020] figure 1 Shows a schematic diagram of an embodiment of a cleaning device according to the prior art, comprising a condenser 4 and a cleaner 1 arranged below the condenser 4 and having a rotatably mounted cleaning roller 3 . The condenser 4 has a screen drum 5 mounted for rotation about a longitudinal axis 7 in a screen drum housing 14 , which is filled with fiber material 2 through channels 17 ; the condenser also has a feed roller 6 (also known as a flap drum), which is mounted for rotation about the longitudinal axis 8 in the feed roller housing 18 .

[0021] The fibrous material 2 is fed to the screen drum 5 by means of conveying air. A vacuum is applied in the interior 26 of the screen drum 5 by a vacuum source 30 . The fibrous material 2 fed in this way is sucked onto the surface 10 of the screen drum 5 and separated from the conveying air 9 by the air-permeable surface 10 of the screen drum 5; was removed. In this process, a web of fibrous material is formed ...

Abstract

The invention relates to a device and a method for cleaning a fibrous material (2). The device has a cleaner (1) and a condenser (4) and a fibrous material (2) pneumatically fed by means of conveyingair (9), the cleaner has a cleaner roller (3) and a cleaner housing (23), the condenser (4) is disposed above the cleaner (1). The condenser (4) has a ventilating screen drum (5) mounted for rotationin the screen drum housing (14) and has a feed roller (6) mounted for rotation in the feed roller housing (18), each has a longitudinal axis (7, 8). The feed roller (6) is arranged between the screendrum (5) and the cleaning roller (3), and with the guidance of the conveying air (9), the fibrous material (2) is guided to the outer surface (10) of the screen drum (5).

Description

technical field [0001] The invention relates to a device and / or a method for cleaning fibrous materials, the device having a cleaner, a cotton condenser having a cleaning roller and a cleaner housing, the condenser being arranged above the cleaner. Background technique [0002] It is known from the prior art, for example from published patent CH 695154 A5, to provide devices for opening and cleaning fibrous articles. With these devices, the fibrous material (for example in the form of fiber bundles) is sent through the conveying channel to the condenser under the influence of the conveying air thus generated. The condenser is provided with a rotatably mounted screen drum. A vacuum generated by a vacuum source is applied to the inside of the screen drum. Therefore, the fibrous material fed to the screen drum is sucked to the surface of the screen drum and deposited there. During this process, the fibrous material is separated from the conveying air. The fiber mat (fibrous...
