(54) УСТРОЙСТВО ДЛЯ ЛИНТЕРОВАНИЯ СЕМЯН ХЛОПЧАТНИКА(54) DEVICE FOR LINTING OF COTTON SEEDS

Изобретение относитс к первичной обработке хлопка и предназначено дл съема линта с сем н хлопчатника.The invention relates to the primary processing of cotton and is intended to remove the lint from cotton seeds.

Известно устройство дл линтеровани сем н хлопчатника, содержащее металлощеточные барабаны, помещенные в закрытый сетчатый кожух, в верхней части кожуха расположен продольный желоб, выполн ющий роль семенной камеры.A device for the spinning of cotton seeds is known, containing metal mesh drums placed in a closed mesh casing, in the upper part of the casing there is a longitudinal chute which acts as a seed chamber.

При работе известного устройства семена заполн ют семенную камеру и кольцевое пространство между барабанами и сетчатым кожухом. При вращении барабанов семенной валик также вращаетс , семена непрерывно унос тс из него и затем возвращаютс обратно. Съем линта с сем н осуществл етс как в семенной камере, так и в кольцевом пространстве между барабанами и сеткой, затем линт отсасываетс через сетчатую поверхность воздушном потоком и собираетс в циклоне, где отдел етс от воздуха 1.During operation of the known device, the seeds fill the seed chamber and the annular space between the drums and the mesh case. As the drums rotate, the seed roll also rotates, the seeds are continuously carried away from it, and then returned. Lint is removed from the seed both in the seed chamber and in the annular space between the drums and the net, then the lint is sucked through the mesh surface with air flow and collected in a cyclone where it is separated from the air 1.

Недостатком известного устройства вл етс мала производительность вследствие плохого отсоса сн того линта из рабочих камер через сетчатую поверхность, что приводит к перетиранию линта рабочими органами , укорочению линта, повреждению кожуры сем н и загр знению линта частицами кожуры, что недопустимо как дл линта, так и дл сем н.A disadvantage of the known device is low productivity due to poor suction of the removed lint from the working chambers through the mesh surface, which leads to the lining of the lint by the working bodies, shortening of the lint, damage to the seed rind and contamination of the lint with rind particles, which is unacceptable for both the lint and for this seed

Цель изобретени - повышение эффективности процесса.The purpose of the invention is to increase the efficiency of the process.

Дл достижени поставленной цели в устройстве дл линтеровани сем н хлопчатника , содержащем рабочие барабаны, параллельно установленные в камере с перфорированным кожухом, св занной с отсасывающей пневмосистемой, кожух камеры состоит из колосников в виде гребней, обращенных зубцами по направлению перемещени материала, при этом гребни установлены тангенциально относительно траектории перемещени материала и с зазором один относительно другого менее минимального размера семени.To achieve this goal, a cotton seedling device containing working drums installed in parallel in a chamber with a perforated casing associated with a suction pneumatic system, the chamber casing consists of grates facing the teeth in the direction of movement of the material, while the crests are mounted tangentially relative to the path of movement of the material and with a gap one relative to another less than the minimum seed size.

На фиг. 1 схематично изображено предлагаемое устройство; на фиг. 2 - вид А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1.FIG. 1 schematically shows the proposed device; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one.

Claims

A device for lining cotton seeds contains a pair of saw drums 1 around which the grate 2 is mounted sequentially and tangentially to their surface, in the form of ridges while the teeth 3 of the ridges are directed to the side coinciding with the direction of rotation of the drums and the distance between ridges is smaller than the minimum size incoming semes n. The drums 1 are located in the chamber 4, which is connected to the air suction system 5, while the air suction system is set in such a way that the direction of movement of the suction air coincides with the direction of the teeth of the ridges. The pipes 6 and 7 serve for feeding and exiting cotton seeds. The device works as follows. Seeds along the nozzle 6 fill the annular space between the drums 1 and the surfaces of the comb grates 2. As the drums 1 rotate, the seed roller rotates, the seeds are continuously carried away from it and then returned. Lint is removed from the seed both in the seed chamber and in the annular space between the drums 1 and the grate bars

2. The lint removed from the seeds is thrown by centrifugal force to the surface of the grate, where long fibers are put on the ridges of the grates 2 and, together with short fibers, are sucked off by the air flow, while the long fibers are removed by air flow from the ridges in the gap between their ends and collected in a cyclone (not shown), and short fibers are removed by air flow both between the teeth of the crests and in the gap between the crests. The tangential installation of the grate 2 allows to obtain zones of intensive removal due to the wedges obtained between the surface of the drums 1 and the surface of the grates 2, which significantly increases the productivity of lintering. Bared seeds through pipe 7 are removed from the device. The implementation of the comb grates allows for the highly efficient removal of both long and short lint, eliminating its damage. The use of the proposed device will significantly improve the performance of the existing equipment for cotton seed listing. Apparatus of the invention for the spinning of cotton seeds, containing working drums, installed in parallel in a chamber with a perforated casing associated with a suction pneumatic system, characterized in that, in order to increase the efficiency of the process, the casing of the chamber consists of grates in the form of ridges facing teeth the direction of movement of the material, while the ridges are set tangentially relative to the path of movement of the material and with a gap one relative to another less than the minimum size of the seed and Sources of information taken into account during the examination 1.
