TH2969B - Separating seeds, granules and the like - Google Patents

Abstract

The pellet separator and its like have a perforated wall split plate mounted on the structure and inclined both lengthwise and vertical. Lateral relative to the level plane and suitable to vibrate in the longitudinal direction while some strokes are raised towards the top.A perforated wall is placed at the top of the air chamber where compressed air is supplied by the machine. Blow through the air pipe. The perforated split discs are constructed with a child surface. The mattress consists of many corrugated lines arranged in a direction perpendicular to The oscillation direction of the split plates and arranged in parallel with the The distance between the rows is not less than the size of the objects to be split. An opening for releasing the separated material is provided at the lower end of the sheet. Split at the wall, drill a hole where the corrugated line ends. Air assisted contact With the upper area of the separator pad, it is built to be able to eliminate Dust and material with a lower specific gravity than the separated metal.

Claims (6)

1. Separator for granular materials such as grains, beans, and similar products. Granular materials consist of a mixture of perfect grains, which have a smooth exterior and tend to roll, and damaged grains, which have a rough exterior. The perfect grains have a higher specific gravity than the damaged grains. Such a separator consists of a movable structure. A perforated separating plate with numerous holes is mounted on this structure and tilted both longitudinally and laterally relative to the horizontal plane in such a way that the perforated separating plate has a lower discharge end, an upper discharge end, and opposite upper and lower lateral edges. The perforated separating plate, together with the structure, defines the lower air vents of the plate. These numerous holes in the perforated separating plate are connected to these air vents. The perforated separating plate is corrugated by creating multiple lines, each extending parallel to the other from the lower discharge end of the plate to the upper discharge end. These corrugations are spaced at least as far apart as the size of each perfect grain. A drive device is connected to the structure to vibrate the structure and the perforated separating plate. The device delivers a mixture of intact and damaged seeds onto the perforated separating plate adjacent to the upper end. Due to the inclination of the perforated separating plate and the arrangement of the corrugations, the seed mixture flows down the perforated separating plate to the lower discharge end. A device is positioned at the lower discharge end of the perforated separating plate to receive the seeds, and a device for delivering compressed air into the air chamber causes compressed air to flow from the air chamber to the area above the perforated separating plate through the holes in the perforated separating plate. When compressed air is received into the air chamber by the air delivery device and the perforated separating plate is vibrated by the structural vibrating device, (a) the intact seeds of the mixture delivered onto the perforated separating plate are precisely oriented towards the upper side edge by the corrugations on the perforated separating plate, and (b) the damaged seeds of the mixture delivered onto the perforated separating plate are driven upward by the airflow through the numerous holes. In the perforated separating plate, because damaged seeds have high wind resistance, they will float to a position above the surface of the perforated plate, above the position of the intact seeds, and will be turned directly towards the bottom edge of the perforated plate due to the higher specific gravity of the intact seeds. 2. The separator according to claim 1 at the aforementioned corrugated line shall protrude relatively perpendicular to the lower discharge end of the perforated separator sheet. 3. A separator according to either claim 1 or 2, where two adjacent corrugations define a groove with a longitudinal plane below that is wider than the size of the largest perfect seed. 4. The separator under claim 3 consists of a cover plate that is firmly attached to the said structure and, together with the said structure, defines a second air delivery chamber above the perforated separator plate. Compressed air delivered to the first air delivery chamber by a compressed air delivery device passes into the second air delivery chamber through the numerous holes in the perforated separator plate. 5. The separator according to claim 4, on the said cover plate, has holes made in it. 6. The separator under claim 4, which delivers the mixture of the said grains, consists of a material hopper with an outlet. The separator also consists of a designated first passage that allows the outlet of the material hopper to connect to the second air chamber, to draw the mixture of grains from the material hopper into the second air chamber, and a designated second passage that connects to the first passage, positioned below the outlet of the material hopper relative to the flow of the mixture of grains from the material hopper to the second air chamber through the first passage, so that the compressed air entering the second air chamber from the first air chamber, through the numerous holes in the perforated separator plate, allows the granular material and dust, which have a relatively low specific gravity relative to the grains, to be discharged from the first passage into the second passage.
