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

First, in describing the present invention, if a detailed description of related known functions or configurations may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 to 3 show the configuration of an aluminum chip forming apparatus that is put into a furnace according to a preferred embodiment of the present invention. According to the drawings, the present invention is provided with a casing 10 having a hopper at the top and a discharge port at the bottom while the inside is sealed, the inside of the casing is provided with a rotating inner cylinder and the inside of the casing and the outside of the inner cylinder, respectively While the fixed cutter and the rotary cutter are attached, the collected aluminum (hereinafter referred to as "material") is crushed into the inside, and the rotating plate 40 is provided at the lower portion of the outer cylinder to discharge the material processed into chips to the outlet. Let's do it.

The above is described in more detail as follows.

First, an upper frame 12 having a hopper 14 formed on an upper surface thereof is attached to an upper portion of the cylindrical casing 10, and a lower frame 16 having an outlet 44 on one side thereof is attached to the upper portion of the cylindrical casing 10. Is installed. In addition, a plurality of fixing cutters 36 separated by the same size are mounted on the inner surface of the casing 10 by assembling means such as screws and bolts, and are detachably assembled. In this case, predetermined cutting blades 38 protruding inwardly are formed vertically long on the inner surface of the fixed cutter 36.

Thereafter, the upper support 22 to which the conical separator 23 is attached is fixed to the inner upper side of the casing. The separating plate 23 has the purpose of dispersing the material introduced from the hopper to the outside. In addition, while the lower support 24 is fixed to the center of the lower frame, the shaft 20 is installed in the center between the upper support 22 and the lower support 24. And the shaft 20 is rotated to have a drive means. The drive means is connected to the drive motor 28 installed on the pedestal 18 from the outside of the casing 10 and the pulley 27 mounted on the drive shaft, and the lower end of the shaft 20 has a lower frame 16. The pulley 26 is connected to the pulley 27 of the driving motor while being exposed to the outside.

In addition, a cylindrical inner cylinder 30 is mounted on an upper portion of the shaft 20 and a rotating plate 40 is mounted on a lower portion thereof to rotate along the shaft. On the other hand, the inner cylinder 30 is provided with an inclined plate 34 to form a predetermined angle on the top. That is, the inclined plate is formed gradually downward from the center to the outside in order to move the material injected from the upper hopper to the outside of the outer cylinder. And, the outer circumferential surface of the inner cylinder 30 is provided with a plurality of rotary cutters 32 are formed long in the vertical direction at regular intervals. At this time, the rotary cutter 32 is curved in the same direction and the same angle.

On the other hand, there is a predetermined interval between the rotary cutter 32 and the fixed cutter 36, the interval is gradually narrowed from top to bottom. That is, as the rotary cutter 32 or the fixed cutter 36 has a gradient, the gap becomes narrower as it goes down, whereby the input material is gradually formed and moved downward. Such spacing may vary depending on the size of the input material and the size of the finished chip. However, the size of the appropriate particle introduced into the deoxidizer is 6 mm in diameter, so the distance between the lower rotary cutter and the fixed cutter It would be desirable to be 7 mm or less, with the top gap being 10-15 mm. Then, the rotating plate 40 installed below the inner cylinder 30 is rotated by the shaft to discharge the chip formed by the rotary cutter and the fixed cutter with a centrifugal force. At this time, the radially arranged guide 42 is formed on the upper surface of the rotating plate and the discharge port 44 is formed on one side. Accordingly, the chip, which is formed by falling down to the upper portion of the guide 42, preferably by waste aluminum, is moved outward by the centrifugal force of the rotating plate and the guide, and discharged to the outside through the outlet. At this time, the exhaust pipe 46 is installed in the upper portion of the discharge port is connected to the external dust collecting pipe.

Referring to the operating state of the present invention configured as described above are as follows.

First, when the collected waste aluminum (material) is introduced into the hopper 14, the material is moved to the outside of the inner cylinder 30 by the separating plate 23 and the inclined plate 34, and then the rotary cutter 32 ) And the fixed cutter 36. Then, the rotary cutter 32 that is rotated while the drive motor is operated is moved downward while crushing or compressing the material introduced therein. At this time, the material is crushed by the inner / outer cutter, and then subjected to the friction of the rotary cutter when moving down between the cutting blades 38 of the fixed cutter. Thus, the material is formed into a generally spherical shape while rolling along the grooves between the cutting edges. Thereafter, the material falls down the cutters 32 and 36 on both sides and falls to the upper surface of the rotating plate 40. At this time, the rotating plate is rotated by the shaft 20, the material is moved to the outside by the centrifugal force and the guide is discharged to the discharge port 44 formed on one side is collected in a predetermined container. At this time, foreign matter such as dust generated inside the casing is collected by an external dust collector (not shown in the drawing) through the exhaust pipe 46.

As described above, the aluminum chip forming apparatus introduced into the furnace according to the present invention can be molded into chips of a desired size without melting, and there is no loss of furnace facilities and fuel required for melting and economical. It does not cause environmental pollution problem because it recycles waste aluminum sludge and scrap which is processed as waste, and molded chips are effectively used as oxidant in steel smelting.
