Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a compound sorting apparatus for removing foreign matters from a raw material. But is not limited to, a raw material for a silicon powder used in a semiconductor device. Foreign substances include non-magnetic substances such as magnetic materials such as flour and organic matter.

The main body 10 according to the present invention is composed of the lower space portions 11 and 12 and the hopper 15 on the upper side. The purity of the raw material can be increased by removing the foreign substances mixed into the raw stone introduced into the hopper 15 through the set conveying path of the main body 10. [

According to the present invention, the conveying means 20 forms a conveying path of the raw material from the hopper 15 of the main body 10 to the discharge cylinder 23. 1 and 2, the conveyance path is exemplified by the inclined path 21 on the upstream side and the horizontal path 22 on the downstream side. On the horizontal path 22, a conveyor for rapid transfer of the raw material can be provided.

As a detailed configuration of the present invention, the conveying means (20) further comprises a multi-perforation tradition (25) having a conveying screw (27) on its inner circumferential surface. Referring to FIG. 3, there is illustrated a state in which the mortise tradition 25 is installed in the horizontal path 22 of the conveyance path. The crowning tradition 25 has a number of through holes in the entire area and is connected to another motor (not shown) and rotated. It is possible to promote the transfer of the raw material by setting the gradient to the porous coin 25 or rotating the feed screw 27 separately. The conveyance screw 27 formed on the inner surface of the perforated plate tradition 25 induces the separation of the foreign material together with the conveyance of the raw material. The removed foreign matter is collected through the lower space portion 12 and a suction fan 56 described later.

According to the present invention, the first removing means (30) sucks the flour by the electromagnets disposed in the conveyance path and sends the flour to the receptacle (38). The electromagnets of the first removing means (30) are provided on the ramp (21) and the scraper (34) comes into contact with one side to remove the foreign matter. This is because using the electromagnet as the first removing means 30 is advantageous in removing foreign matter as compared with the permanent magnet. The separated foreign matter is dropped into a receptacle 38 disposed below the scraper 34.

As a detailed configuration of the present invention, the first removing means (30) is characterized in that the cores (31) divided into a plurality of circumferences are supported by an annular energizing rail (36) . Referring to FIG. 4, four wound cores 31 are shown coupled in a cylindrical shape via an insulator 32. As shown in FIG. Each core 31 has a plurality of terminal rollers 33 for applying power. The terminal roller 33 remains in contact with the inner surface of the energizing rail 36 while the core 31 is rotated by a separate motor (not shown). The arc-shaped power supply terminal is provided on the inner surface of the energizing rail 36 at an angle range (for example, 180 degrees on the upper right side as shown in the drawing). While the core 31 is passing over the upper surface of the inclined path 21, power is applied to draw the powder and the power is turned off while passing through the lower surface of the inclined path 21 to induce rapid desorption of the powdery powder.

According to the present invention, the second removing means (40) forms an air flow on the discharge cylinder (23) and sends the foreign matter to the exhaust pipe (48). The second removing means 40 causes airflow and jetting to the blower 46 mounted on the space portion 11. [ The feed path of the raw material and the injection path of the air cross each other in the discharge cylinder 23 to facilitate the separation and scattering of relatively light foreign matter. An exhaust pipe 48 is provided on the upper side of the discharge cylinder 23 and an exhaust pipe 48 is connected to the space 11.

The second removing means 40 is characterized in that the nozzle plate 45 is positively variable between the upstream duct 41 and the downstream duct 42. [ The upstream duct 41 is installed in the space portion 11 adjacent to the blower 46 and the downstream duct 42 is installed adjacent to the exhaust pipe 48 in the discharge cylinder 23. [ A plurality of filter media (43) are mounted on the upstream duct (41) and the downstream duct (42). A nozzle plate 45 for increasing the velocity of the airflow is installed in a region where the upstream duct 41 and the downstream duct 42 are separated from each other. When the nozzle plate 45 is connected to another actuator (not shown) to change the posture, the airflow velocity can be increased or decreased corresponding to the feeding state of the raw material.

According to the present invention, the sorting means 50 is provided with a plurality of discharge pipes 51 and 52 branched to the discharge cylinder 23 through the sorting plate 55. It is preferable that the sorting means 50 selects the foreign matters as to whether or not the raw materials are sorted by particle size. The raw material to which the foreign substance is adhered is selected as the upstream side exhaust pipe 52, and the raw material to which the foreign matter is not adhered is selected as the downstream side exhaust pipe 51. The raw material passing through the discharge cylinder 23 is cleaned by the air flow between the upstream duct 41 and the nozzle plate 45 but the foreign substance is not removed and the weight of the raw material passes through the upstream plate 52 And is collected in the lower collecting cylinder 58 and then sent to the hopper 15. [

As a detailed configuration of the present invention, the selecting means (50) causes the posture change of the lattice type discriminating plate (55) to change the flow path cross sectional area of the discharge pipes (51) and (52). If the posture of the sorting plate 55 is changed in accordance with the physical properties (particle size, water, etc.) of the raw material to be fed into the conveying path, the foreign matter removing efficiency can be increased. Referring to FIGS. 1 and 3, a state in which the posture of the L-shaped sorting plate 55 is varied is illustrated. The amount of the raw material flowing to the side discharge pipes 51 and 52 varies in accordance with the position of the upper side member of the angled plate 55.

The suction fan 56 mounted in the space 12 of the main body 10 sucks and collects all the foreign matters separated from the discharge cylinder 23 and the receptacle 38 as well as the transfer path.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
