Description

The invention relates to the textile industry and can be used to divide raw cotton into batches.

A device for dividing raw cotton is known, comprising a mesh drum placed in a housing with radial strips inside flj.

However, the known device is characterized by the efficiency of the process of dividing raw cotton into batches.

The purpose of the invention is to increase the efficiency of the process.

This goal is achieved by the fact that a device for separating raw cotton, comprising a mesh drum placed in a housing with radial strips inside, installed with a gap between their ends and the drum surface, means for feeding raw cotton and sucking off a flying exhaust system, is additionally equipped with screed vane. rollers installed with a pitch along the circumference from the outside of the drum parallel to its axis, and the means for feeding raw cotton is placed on the drum, while the suction osistema it communicates with the cavity, and the strap is fixedly mounted, and each of them is directed towards sootvetstvuyuschegs screed roller.

Fig, 1 shows the proposed device, a general view; FIG. 2, view A of FIG. 1} in FIG. 3 is a flowchart of dividing raw cotton.

device contains means 1

10 feed of raw cotton and a mesh drum 2 located under it, with cells commensurate with the hlpka-gsyrts battles. Outside The sides of the drum 2 are installed, with a certain pitch along the circumference (differently of its axis) by leveling the blade rollers for 3 s; forming a clearance to the net surface of the drum up to 3 mm, the Mesh drum 2 and the rollers 3 are enclosed in the casing 4. Inside drum 2 (on a fixed axis 5) radial strips 6 are mounted, installed with a gap between their ends and the surface of drum 2, and each of

25 strips 6 are directed towards the corresponding leveling roller 3. The mesh drum is fixed on the hub 7, which, in turn, is located coaxially on the axis 5 and can be rotated by means of a pulley 8. the suction pneumatic system (not indicated) communicates with the cavity of the drum 2 from open its ends. In the case of processing of clogged raw cotton between the rollers 3, a vacuum valve 9 can be installed in the lower part of the mesh drum 2.

Raw cotton is fed to the rotating mesh drum 2 and (due to the organized suction of air through its internal cavity) sticks to the outside of the mesh drum 2. Falls under the impact of the screed vane roller 3, raw cotton bats oriented against the mesh surfaces of the drum 2, The blades of the roller 3 are inserted into its internal cavity, where they are separated from the total mass of material by the radial bar B and sucked into the ends of the drum 2, the excess cotton raw material that did not enter the cavity of the bar Abana 2, feathers The blades of the roller 3 are cut out and are affected by the roller 3 next around the drum, where the process of separating raw cotton is repeated.

In the case of the presence of large weed impurities in raw cotton, the latter, due to the low coefficient of windage in relation to the raw cotton sheaves, are rolled into the vacuum valve 9 and removed from the device.

which ensures high technological reliability of the device.
