Abstract

The invention relates to the ginning industry, can be used in devices for separating fiber from cotton seeds and allows for an increase in fiber separator productivity. The working chamber is made of two communicating parts with a agitator in each of them. The chamber is divided by a curvilinear separator with concave surfaces facing each agitator. The ratio of the radius of curvature of these surfaces of the separator to the diameter of the agitator is not more than two. The separator is installed with the possibility of transfer of seeds from the upper part of the chamber to the lower one and back under the action of the saw cylinder. To do this, there are two channels, one of which is formed by the surface of the apron and the separator, and the other by the separator and saw cylinder. The density of the seed roller in the upper part of the chamber and the flow of seeds to the lower part are regulated by changing the width of the channel when the density adjuster is rotated in the form of a moving apron wall. 1 hp ff, 1 ill.

Description

The invention relates to the cotton ginning industry and can be used to separate the fibrous cover from the cotton seeds.

The purpose of the invention is to increase productivity by intensifying the process of separating the fiber from the seed.

The drawing shows the saw fiber trap.

The working chamber of the fiber-separator is made in the form of two communicating seed chambers and contains a front beam 2 adjacent to the inlet neck 1 with a grate 3 installed with a gap relative to the inter-layer shims 4, the saw cylinder, the upper curvilinear apron 5 with a rotary CTCHKOII 6 - with a density regulator of the seed shaft The lower curved apron 7, adjacent to its lower part, is a curvilinear seed comb in the form of a rotary sector 8, two Bopoimi bodies 9 and 10, and a curvilinear divider 11, located between knockers,

Seeds from the feeder through the inlet neck 1 enter the cavity of the upper chamber, where under the action of the isopicine 9 and the saw cylinder (continuously rotating rotating axial roller.

The space from the place of entry of seeds into the chamber between the inner surface of the upper apron 5, its pivoting wall 6, the separator 11 and the cylindrical surface of the agitator 9 gradually narrows, due to which the seeds are fed to the surface of the saws with a dense mass and pressed against the tooth of the saw cylinder.

The density controller, which is the rotary part 6 of the apron 5, is designed to control the density of the seed roller formed in the upper and lower parts of the working chamber. When a high density is created in the upper part, the density regulator from the pressure on the seeds moves away from the spider, as a result of which the distance between it and the distributor becomes larger and the flow of seeds from the upper part of the chamber to the lower increases

Dp ordering the movement of the seed roller in the space between the two agitators establishes a curvilinear separator, along the upper (see drawing) curvilinear surface of which the seeds move to the saw cylinder, and along the lower curvilinear surface from the saw centerpiece of the chindra into the cavity of the lower part of the chamber.

To avoid damage to the seed, the gap between the surface of the saw cylinder and the end of the splitter should not be less than 1.5 times the cotton seed, and the radius of curvature of the concave surfaces of the splitter should not exceed the diameter of the turners.

In the lower part of the chamber, the seeds are transported under the action of the agitator 10 into the space between the cylindrical surface of the agitator 10 and the inner surface of the lower apron 7. This space also gradually narrows from the point of entry of the seeds to meeting them with the cylinder saws, where the seeds are fed to the meeting area with the teeth saws compacted mass and pressed to them under the action of the agitator. Dp of unloading linter seeds and adjusting the removal of lint from seeds at the bottom of the apron 7, a seed comb with a curved surface is installed. Lint removal is regulated by changing the gap between the seed comb 8 and between the saw blade 4 by

rotation of the sector around its axis, was located outside the cavity of the working chamber.

In the space between the separator 11 and the saws of the cylinder, the seeds are separated: the less lowered seeds are returned to the lower part of the chamber by the action of the agitator 10, the more lowered seeds are sent to the upper part of the chamber by the action of the saw teeth.

Seeds from the lower part of the chamber, together with the seeds of the upper part, are directed to the zone between the agitator 9 and the cylinder saws, where the intensive process of separation of the fibrous cover from the seeds takes place. Thus, the seeds repeatedly fall into the zone of intense separation between the two agitators and the saws. The process of red tape is intensified, which allows to increase the performance of the fiber separator.

In the proposed chamber, the use of a curvilinear separator in conjunction with a density controller allows two interconnected rotating seed pulses to be formed, to order the movement of seeds in the space between the agitators, which ensures the linting process with the greatest efficiency.

The seed comb is made convex, and a certain angle is formed between the tangents to the lower part of the apron and to the surface of the seed comb. Due to this, in the lower part of the chamber a so-called rarefaction zone is formed, formed by these tangents and the surface of the saws, where a more efficient separation of the untreated and already processed seeds and their removal from the chamber occurs. In addition, a change in the gap between the seed comb and the interdiscipulating pad also provides favorable conditions for withdrawing the treated seeds from the chamber, since the direction of the tangent to the part of the comb forming the required interstitial clearance coincides with the direction of movement of the seed left by} 1x working the camera.

the intensive mixing of seeds increases the zone of contact of the saw cylinder with seeds as a result of lengthening the arc of entry into the chamber from the place where the seeds meet at the seed comb before entering the grate.

Intensive mixing of the seeds by two agitators, an increase in the zone of contact between the saw cylinder and the seeds allows to intensify the process of fiber separation and to increase the productivity of the fiber separator.
