Abstract

The invention relates to the textile industry and reduces the formation of free fiber. The raw cotton bolls that fell out together with weed impurities through the grate 12 are captured by the regenerating sawtooth drum 20, fixed on it with wiping brushes 21, 22, worn from weed impurities on the grate 23, then removed from it (L N)

Description

13 and are fed to the main sawtooth drum 10, from which they are removed together with the raw cotton on it and are also fed to the drum drum 8. Weed impurities through the grate 23 fall into the tank 24, where they are mixed with impurities, selected through perforated grids 9 and 15. Thanks to the installation of the main additional feeding roller in series and placement between the last

one

The invention relates to textile impregnation, can be used at ginning factories and procurement centers in determining the weed infestation of cotton and is additional to auth. 93182A.

The purpose of the invention is to reduce the formation of free fiber.

The drawing shows the proposed device

The device contains a hopper for loading a raw cotton sample, formed by inclined trays 1 and 2 and a hinge-mounted lid 3, feeding the spike rollers 4 and 5 mounted successively in the material feed direction, a guard 6, two spiky drums 7 and 8 with a perforated mesh 9, serrated drum 10 with a wiper 11 and a grate 12, a removable drum 13, a guide visor 14, a flap 15 in the form of a perforated mesh fixed on a rotary shaft 16, a valve 17, capacity 18 for an effective cotton -syrtsa, the tray 19, the regeneration serrated drum 20 with a wiper brushes 21 and 22, grate 23, and tank 24 for a litter. Between the main serrate drum 10 (the first in the direction of material feed by the drum 8 of the Kolkovo section) and the additional feed roller 5, a dividing shield 25 is installed at an angle to the horizontal of at least 55

the main sawmill drum and the first in the material feed direction of the drum of the Kolkovo section of the separation shield the cleaning of raw cotton on the Kolkovo and main sawed drums is carried out simultaneously. Under the influence of the drum drums, all the bolls from the portion of the raw cotton being cleaned constantly moving The frequency of cleaning raw cotton on the serrate drum is reduced by a factor of 8.

25 is adjacent to the visor 14. The feed rollers 4 and 5 are rotatably mounted in one direction.

A sample of raw cotton of a certain weight is placed in a receiving hopper, and raw cotton is fed into the device by feeding rollers 4 and 5, after which the lid 3 is closed. At the same time, the valve I5 is in the working position at the spiky drum 8, and the valve 17 blocks the discharge opening and serves as a tray for directing the weed impurities separated through the perforated grids 9 and 15 into the tank 24.

Raw cotton under the influence of the feeding roller 4 and the spike drum 8 is fed to the upper part of the dividing shield 25, from where a smaller part of it is fed by an additional feed roller 5 to the serrate drum 10, and the greater part of it is moved along the dividing shield 25 by g. and, flying over the channel formed by the guiding visor 14 and the inclined chute, is cleaned with the drum pins 8 and 7 on the perforated grids 15 and 9.

The weed impurities that are isolated in this way fall out into the tank 24, and the raw cotton returns to the zone between the drum b and the feed roller 4, where it is mixed with the remaining cotton that continues to flow from the receiving bin.

At the same time, the raw cotton fed to the sawing drum 10 is fixed on it with a wiper 11, cleaned of weed impurities on the grate 12, then removed from it by the removal drum 13 and guided through the channel formed by the visor 1 and the inclined tray, to the spike drum 8, where it is mixed with raw cotton, cleaned with spike drums 7 and 8.

The raw cotton bolls that fell out together with the weed impurities through the grate 12 are captured by the regenerative sawtooth drum 20, are fixed on it with wiping brushes 21 and 22 are cleaned of weed impurities on the grate 23, then removed from it by the removing drum 13 and served on the main sawed drum 10, which is removed together with the raw cotton on it and also fed to the drum drum 8. Trapped through the grate 23, weed impurities fall into the tank 24, where they are mixed with mi allocated through the perforated grid 9 and 11.

After the time required for complete cleaning of the raw cotton, the valve 17 and the flap 15 are automatically set to the open position (drawing, dash-dotted lines) and the cotton with the lower spiky drum 8 is discharged into the container 18 for the cleaned material.

Due to the sequential installation of the main additional feed roller and placement between the last, main sawed drum and the first drum in the feed direction of the material of the drum section of the separation plate, the raw cotton on the drum and the main sawtooth drums are simultaneously cleaned.

on the serrate drum, it is continuously fed into the raw cotton stream moving around both barreled drums, and from this stream, part of the bat is fed to the serrate drum. By the action of the impact of the spinning reels, all the volatiles from the portion of the raw cotton being cleaned are constantly mixed, as a result of which the frequency of cleaning the raw cotton on the serrate drum is reduced by a factor of 7–8. This helps reduce free fiber formation.

In addition, with the proposed mutual arrangement of the working bodies, the content of coarse litter in the cleaned raw cotton is almost zero, and the fine litter is within the required accuracy of the analysis.

Due to the fact that the separation flap is located relative to the horizontal, the occurrence of raw cotton on the separation flap and ensures its complete withdrawal from the device after the cleaning time, which increases the accuracy of the analysis.
