Description

Technical Field The present invention relates to a pneumatic separating apparatus for aluminum granule,

The present invention relates to an aluminum granule wind force sorter, and more particularly, to an aluminum granule wind sorter for efficiently separating aluminum granules and foreign matter, thereby improving screening efficiency and purity of aluminum granules, and accurately separating aluminum granules and foreign matter from each other So that the recovery rate of aluminum granules can be remarkably increased.

With increasing use of aluminum, there is a growing interest in the aluminum recycling industry for processing waste aluminum into high purity aluminum granules.

Particularly, various researches on aluminum regeneration technology having purity and recovery rate are proceeding due to the characteristics of Korea with a high consumption of aluminum and the disadvantage that the unit price of aluminum pellets of high purity is excessively high.

Accordingly, the present applicant has proposed a technique for cracking waste aluminum scrap with an aluminum chip in a domestic registered patent No. 10-1207516 (entitled "Aluminum scrap cracking apparatus") as a domestic patent No. 10-1310613 The high speed milling of aluminum chips in aluminum granules at a high speed in a single-speed aluminum granule high-speed milling machine has been patented. However, there is not much research on the screening device for increasing the purity and recovery rate of waste aluminum.

In this case, the wind-based method is widely used as a screening method for selecting foreign matters from the screening objects, but the research on the wind-screening apparatus considering the characteristics of aluminum which has low specific gravity and is not spreadable due to aggregation is insufficient .

Korean Patent No. 10-0610637 (entitled " Wind turbine screening apparatus for construction waste and method thereof ") discloses a wind turbine system in which construction waste is arranged in various directions at different angles, The wind screening apparatus is effective for construction waste having a high specific gravity but is applied to aluminum granules having a low specific gravity when a high pressure air The aluminum granules are scattered in all directions, and thus the scattered aluminum granules flow into not only the discharge port but also the foreign matter discharge port through which the foreign substances are discharged.

In addition, Korean Patent No. 10-0712617 (entitled " Recyclable Garbage Separation & Separation Device Using Wind Power ") discloses a sorting and separating device for sorting low specific gravity materials and high gravity materials using wind power. Since the sorting apparatus has no separate means for uniformly spreading the aluminum granules when the aluminum granules are applied, the aluminum granules are introduced into the swash plate in a loose state, and the foreign materials are also dropped together with the aluminum granules, Which is not accurately performed.

In addition, since the powder falling down when the aluminum granule is applied is formed at the position where the wind is affected and the inlet is separated from the aluminum granule, the aluminum granule is scattered in all directions by the wind force, .

1 is a side cross-sectional view showing a domestic registered patent No. 10-0779722 (entitled "Separation and sorting apparatus for resin of recycled product").

In the wind power sorter 100 of FIG. 1, the glass bottles and the synthetic resin containers contained in the recycled products of the storage tank 40, which are collected in size, are compressed by the wind force means 110, The glass bottles of the recycled products and the synthetic resin containers are scattered by the compressed air of the wind power unit 210 and the glass pieces branched from the wind power unit 110 at different distances according to the specific gravity difference, And is distributed and discharged to the sickness volleyball 120 and the mood volleyball 130 for synthetic resin.

However, in the prior art 100, when the aluminum granule is applied to the sorting object, the aluminum granule does not spread well, so that the aluminum granules flowing into the hopper 140 are directly transferred to the multi-stage sloping passage 150, The foreign substances contained in the aluminum granules fall down in a state that they are not well separated from the aluminum granules, thereby deteriorating the sorting efficiency of the foreign substances.

In addition, since the prior art 100 does not consider the characteristics of aluminum having a low specific gravity at all, when the air force compressed by the aluminum granules in which the wind turbine 110 falls is scattered, the aluminum granules are scattered in all directions and are not accurately discharged to the desired outlet But rather causes a problem of lowering the recovery rate.

In order to select the wind power of the aluminum granule in this way, it is necessary to 1) distribute the aluminum granules in a state in which the aluminum granules are not bundled together, and then drop the aluminum granules; 2) accurately discharge the aluminum granules to the discharge portion when the wind power and wind pressure are affected Must be achievable.
