RU1772225C - Raw cotton ginning device - Google Patents

Abstract

The invention can be used in ginneries in drying and cleaning workshops after drying of raw cotton. The purpose of the invention is to reduce atmospheric dust emissions and increase the efficiency of cleaning cotton from impurities. Raw cotton from the shaft is picked up by feed rollers and fed to the first ring drum, which throws cotton onto the perforated cylinder. In the interaction of the perforated cylinder and the annular drum, the raw cotton undergoes intensive loosening and due to suction of water from the cylinder, dust and litter are effectively released, which are piped to the dust collector. The cleaning of the material occurs due to the intensive loosening of the material by the ring drums and dragging it along the nets while dust is sucked through the perforated cylinder. 1 ill.

Description

The invention relates to the textile industry and can be used in ginneries in drying and cleaning workshops after drying of raw cotton.

A device is known for cleaning raw cotton, comprising a housing and a cleaning chamber installed therein with a material supply unit located in the ceiling, formed by a horizontally mounted drive auger fiber conduit and ripping ring drums installed on its periphery with mesh debris-forming surfaces forming walls a cleaning chamber, and a screw debris installed in the bottom of the housing.

The disadvantage of this device is that weed impurities are released only

mineral dust is not sucked off through the drum mesh surfaces.

The purpose of the invention is to increase the cleaning efficiency of raw cotton.

This goal is achieved in that a device for cleaning raw cotton, comprising a housing and a cleaning chamber installed therein with a material supply unit located in the ceiling, formed by a horizontally mounted driving cleaning drum and rotating ripping ring drums installed at its periphery, surrounded by mesh surfaces forming the walls of the cleaning chamber, and installed in the bottom of the housing a screw discharge, cleaning drum sample Call soeCh XI

lined with a suction system with a perforated cylindrical shell, and a plate casing with brush sealing strips in contact with the shell along its length is installed over the casing for a part of the arc along its circumference,

The drawing shows a diagram of a device for cleaning raw cotton.

The device comprises a shaft 1 with feed rollers 2, ripping ring drums 3, a cleaning drum with a perforated cylindrical shell 4, sealing brush strips 5, a plate casing 6, mesh debris surfaces 7, and a cone sump 8.

The device operates as follows.

The raw cotton from the shaft 1 is captured by the feed rollers 2 and fed to the first ripping ring drum 3, which throws the raw cotton onto the first cleaning drum with a perforated cylindrical shell.

In the interaction of a rotating cleaning drum and a loosening peeling drum, the raw cotton undergoes intensive loosening and, due to the suction of air from a cylindrical perforated shell, an effective separation of dust and weeds, kotp ;; „.; ps the pipeline is supplied with a dust-

the core drum changes direction and is then cleaned on the mesh surfaces 7.

Weed impurities released through

mesh surfaces 7 are withdrawn from the device by a screw discharge 8.

The use of the device in the drying and cleaning workshop of the cotton mill will significantly reduce dust emissions during the process of the cotton mill and, by reducing weed impurities in the fiber by 0.15%, obtain an economic affect of the order of 18.4 thousand rubles.
