Description

[0001] Aluminum cans grinding device [0002]

The present invention relates to an aluminum can crushing apparatus, and more particularly, to an aluminum can crushing apparatus comprising a plurality of adjusting blades having longitudinal teeth and a plurality of adjusting blades having transverse teeth arranged concentrically, And the aluminum can is milled in the form of granules by the longitudinal teeth and the lateral teeth, and the outlet is formed between the adjusting edges to allow the granulated granules to be discharged, To an aluminum can grinding apparatus capable of changing the size of the granules.

Generally, after the use, the discarded aluminum can is collected and processed into the form of pellets. At this time, the empty can is heated by the heating means to remove the coating layer or the impurities, and then the pellets are formed into granules in the pulverizer. Such aluminum pellets are used to remove oxygen gas and impurities contained in molten iron.

Conventional Patent No. 698446 discloses a method of manufacturing a can material having a predetermined size by assembling a material for a can made of steel or aluminum into a pellet having a predetermined size and comprising a supply port for supplying the can material, And a hammer which is provided in the chamber and forms a pellet by applying an impact to the material of the can. The chamber is provided so as to face the outer circumferential portion of the rotating body, and has a surface facing the outer circumferential portion of the rotating body, And a screen portion formed with a curved surface in accordance with a rotation trajectory while maintaining a predetermined distance from the rotation trajectory of the screen.

However, the conventional grinding apparatus has a disadvantage in that the size of the pellet passing through it can not be controlled in various ways, since the take-out hole formed in the screen unit can not be controlled and manufactured. The size of the pellets varies from 10 mm to 40 mm depending on the application. Conventional take-out holes are fixed in a fixed size, so that there is a need to replace the screen portion in order to adjust the size. Further, since a screen portion having a take-out hole of various sizes needs to be provided, manufacturing costs are increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus and a method for disposing a plurality of adjusting blades having a plurality of fixed blades and horizontal blades having vertical blades on a concentric circle, The aluminum can is milled in the form of granules by the longitudinal teeth and the lateral teeth, and the outlet is formed between the adjusting edges to allow the granulated particles to be discharged, To thereby adjust the size of the granules to be ground.

It is another object of the present invention to provide an aluminum can grinding apparatus in which means for adjusting the intervals of the plurality of adjusting blades are provided so that the adjustment of the adjusting blades can be performed more quickly and conveniently than when the individual adjusting blades are individually adjusted .

To this end, the present invention is characterized in that a plurality of fixed blades and transverse blades having vertical teeth are provided on the body in a concentric circle with a plurality of adjustment blades, an aluminum can is inserted between the fixed blades, A plurality of rotating blades for rotating the aluminum can in the form of a pellet are provided at the center of the fixed blades and the adjusting blades at a high speed while the ends thereof are close to the horizontal blades and the vertical blades In the aluminum can crushing apparatus, both ends of the adjustment blades are provided with a plurality of chain saws fitted between the outlets; Said wedges being connected by a connecting shaft to simultaneously advance and retract at said outlet so that the gaps of said adjusting blades are simultaneously narrowed or open; The adjustment blades corresponding to the fixed blades are provided at both ends with springs corresponding to the blades so that the adjustment blades are elastically moved when the blades are rotated forward and backward.

According to the present invention, the stationary blades and the adjustment blades arranged concentrically are provided on the surface such that the longitudinal teeth and the lateral teeth cross at right angles. Accordingly, the aluminum cans to be crushed by the rotary blades are finely cut between the horizontal teeth and the vertical teeth which are close to the end of the rotary blade and are dried in the form of granules.

Aluminum cans, which are cut and dried in granular form, are discharged through gaps between adjusting blades, which can be adjusted in size to accommodate the size of the granules. In addition, the plurality of adjusting blades are not individually adjusted, but are adjusted at the same time by one adjusting means. To this end, the blades are inserted into both ends of the adjusting blades, The gap can be adjusted at the same time so that the gap can be adjusted quickly and conveniently.

1 to 5, the grinding apparatus of the embodiment of the present invention includes a pair of fixed blades 10 disposed concentrically and spaced apart from each other, and a plurality of adjusting blades (not shown) disposed concentrically with the fixed blades 10 20 are provided. At this time, a discharge port (22) is provided between the adjusting blades (20), and a charging port (41) for charging an aluminum can is provided between the fixed blades (10)

The fixed blade 10 and the adjusting blade 20 are provided in an arcuate shape and are provided with longitudinal teeth 11 and transverse teeth 21 orthogonal to each other on the surface of the fixed blade 10 and the surface of the adjusting blade 20. [ . The vertical cogs 11 and the horizontal cogs 21 are formed by repeating the mountains and valleys of a predetermined pitch so that the aluminum cans are divided in the longitudinal direction by the longitudinal cogs 11, It is cracked in the form of granules.

A rotating shaft 32 is provided at the center of the fixed blade 10 and the adjusting blade 20. The rotary shaft 32 is rotated at a high speed by a motor and is rotatably supported by bearings 42 on both side walls of the body 40. A plurality of rotary blades 30 connected to the rotary blades 31 by pins 33 are provided on the rotary shaft 32 at regular intervals. The ends of the rotary blades 30 come close to the teeth 11 and 21 of the fixed blade 10 and the adjustment blades 20 to crush the aluminum can in the form of granules.

A guide rail 55 is provided at both ends of the adjustment blades 20 and a wedge 50 is provided in the guide rail 55 to be inserted into the discharge port 22 between the adjustment blades 20. The wringer 50 is a means for adjusting the distance between the discharge ports 22. The wringer 50 is provided with a connection ring 51 at the end thereof so that the wringers 50 can move simultaneously. 52 are inserted. An adjusting screw 53 is provided at the center of the connecting shaft 52 so as to protrude to the outside of the guide rail 55 and the adjusting screw 53 is fixed by a fixing nut 54. A spring 56 is provided at a position where the adjusting blade 20 and the fixed blade 10 are in contact with each other so as to correspond to the blade 50. The spring 56 presses the adjusting blades 20, (50) so that the outlet (22) between them is always at a constant interval.

In the grinding apparatus of the embodiment of the present invention configured as described above, the plurality of fixed blades 10 and the adjusting blades 20 are arranged concentrically with the circular arc shape. At this time, the fixed blades 10 are fixed to both side walls of the body 40 at both ends, and the adjusting blades 20 are movably fitted to the guide rails 55 fixed to both side walls of the body 40.
