SU62135A1 - Cleaner for raw cotton - Google Patents

Description

Known cleaners for raw cotton include a spiky loosening drum with a mesh deck, a bilder drum with a spline drum located under the last sprinkling drum, and a series of successively installed calyx loosening drums equipped with mesh decks.

Such cleaners, however, are not sufficiently effective in operation, since they do not produce a vigorous redistribution of fibers in the layer, which causes separation of impurities from the raw material and the deposition of the latter out through the decks, when passing a layer of raw cotton from one spiky drum to another.

The proposed cleaner for raw cotton, in order to remove the intended. disadvantage, has the peculiarity that for redistributing the FIBER a layer of cotton, the channel in which the drums are located is wavy, and the drums themselves are located in the lower depressions of the channel.

The upper canals of the channel can also be made reticulated to more vigorously remove the soot from the cotton.

The drawing schematically shows a longitudinal section of the cleansing.

The cotton cleaner has a cotton receiving chamber / mounted in the upper part of the case of the cleaner and an air separator for venting air from the raw cotton entering through the pneumatic tube 2 into the upper part of the chamber /. The lower part of the chamber / side is connected by a pipe 3 with the exhauster 4, and a conventional rotary vacuum valve 5 mounted under the rotating blade 5 of the upper part of the chamber is designed for taking out the cotton cleared from air 1. Under the vacuum valve 6, a rotary loosening drum 7 is installed, partially surrounded by a lattice deck 8, passing into a flat curved board with a control comb 9, which is adjustable at its end, and a comb 9, connected at a short distance to the drum 10, throwing cotton on the saw drum //. Drum P is equipped with a grate 12. For removal from the grating 12 little loosened lumps of raw cotton, carried away upwards

the saw drum 11, are designed with a fender 13 and reversible 14 bar bows, returning lumps along the corresponding cattle board back to the loosening drum 7. Removable brush drum 15, interacting from the top with the saw drum //, is designed to remove the last from raw material discharged into the receiving funnel Yes and Kolkovi loosening drums 16. These drums are located in an inclined channel formed by the side walls of the numerator case and wavy net decks 17 and 18.. The loosening drums 16 are located in the depressions of the waves. lower corrugated deck 18. To reduce the dimensions of the cleaner, the channel enclosing the drums 16 may have, in the final part, passing into the outlet 19, the inclination opposite to the inclination of the initial part.

To remove the raw cotton impurities that pass through the mesh decks 17 and 18, the screws 20 are designed, located in the respective grooves of the lowest parts of the decks 17 and 18.

The presence of wavy mesh decks 17 and 18, forming a channel for moving raw cotton in the proposed cleaner from one drum to another 16, in the hollows of the bottom deck 18, promotes the redistribution of fibers in the cotton layer as it passes through the cleaner and allows an increase in cleaning ability.
