Description

one

The invention relates to plants for removing fibrous cover (lint) from cotton seeds.

Installations are known, consisting of a chamber, devices for feeding seeds into it, moisture and a gas mixture, a brush obolitel and ventilation blades.

These plants are bulky, energy-intensive, have a large number of individual units, are laborious in operation and maintenance.

The purpose of the invention is a more rational arrangement of elements and simplification of the structure.

For this, the chamber is divided into sealed sealed hermetic compartments for treating seeds with moisture, gas mixture and for exposing them, in which is placed an endless conveyor formed by two parallel mesh belts.

The rim is made in the form of parallel moving brushes installed in the lower compartment of the chamber, on the outside of the mesh conveyor belts.

A bath with running water is installed in the lower compartment of the chamber to remove and prevent degradation of the lint.

The mesh sizes of the conveyor mesh belts correspond to the calibration sizes of cotton seeds.

In order to seal the compartments, rollers with elastic coating and interacting with conveyor belts are installed in their walls.

The drawing shows schematically the installation.

It consists of a bunker 1, feeding the seeds of the drum 2 and a chamber divided into three compartments 3-5, nozzles 6, 7, brushes 8, a bath 9 for running water, an endless conveyor with mesh tapes 10, And, rollers 12 with an elastic coating and ventilation blades 13.

The installation works as follows. Cotton seeds from a bunker with a thin layer

served by the drum on a moving conveyor. At the entrance to the upper, humidifying, compartment, the conveyor belt presses the seed layer, and further the tapes move in parallel with respect to one another. In this compartment, the seeds are moistened with sprayed moisture coming from the nozzle. Then through the rollers the seed conveyor passes into the middle, gas processing, chamber compartment. Here the seeds are treated with gas.

a mixture, such as hydrogen chloride, coming from the pipe of this compartment. Rotating blades create a through flow of the E two compartments.

Then transporter through the next pair

rollers feeds seeds to the lower, naked, compartment where the brushes make a reciprocating movement. The bristles of the brushes, the passage through the mesh surface of the conveyor belts, grind the seeds. Since the force of adhesion of the cushion to the surface of the seed coat is negligible after gas treatment, the seeds are exposed without damage because there are no metal parts.

The resulting lint is poured into running water to neutralize it from hydrogen chloride, since even for a short period of time in transporting devices (for example, in pipelines, cyclones), the lint is almost completely destructed as cellulose.

Bared and mature seeds leave the chamber, while unripe seeds of smaller size pass through the openings of the mesh conveyor belt and also fall into the water and then are caught in the water flow. This operation replaces the laying machine, sucking the lint and transporting it to the cyclone, replacing the cyclone itself and the sizing machine.

The plant, having dimensions of about 1.5X1.5X X0.5 m, can replace the equipment of the workshop for exposing cotton seeds to a chemical-mechanical method.

The plant can be mounted on a vehicle, which will exclude the transportation of cotton seeds from the process.

A plant for exposing cotton seeds, containing a chamber, devices for feeding seeds, moisture and gas mixture into it, a brush base and ventilation blades, characterized in that, in order to more rationally arrange the plant elements and simplify its design, the chamber is divided into light-sealed hermetic compartments for treating seeds with moisture, gas mixture and for exposing them, in which is placed an endless conveyor formed by two parallel mesh belts. 2. Installation under item 1, characterized in that the debonder is made in the form of parallel moving brushes installed in the lower compartment of the chamber, from the outside mesh conveyor belts. 3. Installation according to claim 1, characterized in that, in order to remove and prevent the destruction of the lint, a bath with running water is installed in the lower compartment of the chamber. 4. Installation according to claim 1, characterized in that the cell sizes of the mesh belts of the conveyor correspond to the calibration sizes of the cotton seeds. 5. Installation according to Claim. 1, other than the fact that, in order to seal the compartments, rollers are installed in their walls, having an elastic coating and interacting with the conveyor belts.
