The rotary shaft drive motor 300 is connected to the rotary shaft 200 to rotate the rotary shaft 200 .

The rotary shaft drive motor 300 is connected to the rotation shaft 200 by a known power transmission device such as belt transmission or chain transmission.

The sealing blade 400 is formed on the front of the rotating shaft 200 to cut the bag introduced into the drum 100.

That is, as the sealing blade 400 is disposed below the inlet 110 of the drum 100 and rotates together with the rotary shaft 200, the bag inserted into the drum 100 through the inlet 110 will cut

The paring blade 400 is formed to extend in a spiral shape along the longitudinal direction of the rotating shaft 200. According to this structure, the bag cut by the sealing blade 400 and the waste battery contained in the bag are transferred to the rear by the rotation of the sealing blade 400.

The breaking hammer 500 is formed at the rear of the rotating shaft 200 to crush the bag fed into the drum 100.

The bracket 510 and the shank 520 may be mutually coupled by a bolt fastening method.

The head 530 has a structure in which the upper part is flat but elongated from side to side. Accordingly, the head 530 is configured to be able to adjust the angle formed by the upper portion of the head 530 when the coupling shaft 521 and the boss 531 are coupled. In this case, each of the breaking hammers 500 may be arranged in a spiral shape by arranging an angle formed by an upper part of the head 530 with respect to the rotational direction of the rotating shaft 200 . In addition, by adjusting the angle formed by the upper part of the head 530, the speed at which the bag and its contents are transported by the rotation of the breaking hammer 500 can be adjusted according to the type of the bag and its contents.

According to the above structure, the air passing through the lower vent 1213 of the lower screen 1210 collides with the upper crosspiece 1232 of the upper screen 1230 and is widely distributed back and forth, passing through the upper vent 1233. As a result, it is possible to more smoothly float synthetic resin and dust having a low specific gravity in the metal mixture injected into the screen unit 1200 .

As shown in FIG. 11 , lower hooking parts 1214 protrude from the upper portions of both sides of the lower cross bar 1212, and the upper inner surface of the lower frame 1211 faces both sides of the lower cross bar 1212. A lower catching groove 1215 into which the lower catching portion 1214 is inserted is formed.

Two connection rods 1330 are provided to connect both eccentric parts 1312 formed on the eccentric shaft 1310 and both sides of the screen part 1200, respectively.

The screen driving motor 1320 is connected to the main body 1311 of the eccentric shaft 1310 by a known power transmission device such as belt transmission or chain transmission.

As a result, the screen driver 1300 vibrates the screen unit 1200 back and forth as the connecting rod 1330 reciprocates back and forth by the rotation of the eccentric shaft 1310.

The blower 1400 is installed on the lower side of the screen unit 1200 and blows air from the lower side of the screen unit 1200 toward the upper side.

The blower 1400 is installed so that its discharge port covers the lower surface of the screen unit 1200, so that air can be efficiently sprayed toward the screen unit 1200.

An edge of the exhaust hood 1500 and an edge of the screen unit 1200 are connected to each other by a shielding film 1800 . The shielding film 1800 blocks the space between the exhaust hood 1500 and the screen unit 1200 from the outside, so that air passing through the screen unit 1200 can be discharged only through the exhaust port 1510 of the exhaust hood 1500. let it be

Meanwhile, the exhaust hood 1500 is installed and fixed to the frame 1100 or a separate structure, and the screen unit 1200 is installed to oscillate back and forth. Accordingly, the shielding film 1800 is like a canvas. It is preferable to block air but be made of a material having flexibility.

The discharge part 1600 is formed at the rear end of the screen part 1200 and is for discharging valuable metal that has passed through the screen part 1200 .

The discharge unit 1600 may be formed of a chute mounted on the rear end of the screen unit 1200 .

According to the specific gravity separator P6 configured as described above, it is possible to smoothly separate suspended solids having a low specific gravity and valuable metals such as copper having a high specific gravity from the metal mixture discharged from the first cyclone P5.
