The bridge frame 410 connects the inner frame 100 and the outer frame 400 to each other, A space can be secured so that the conveyor 900 can be installed.

The rotor 200 may be installed to be rotatable with respect to the inner frame 100. More specifically, the transmission unit 200 may be attached to the shaft 210 of the rotor 200, and the transmission unit 200 may be connected to the electric motor 230. That is, the rotor 200 can be rotated by the operation of the electric motor 230.

By the rotation of the rotor 200, the electronic waste can be crushed and crushed. Whereby the electronic waste can be crushed into small sized pieces.

The filter frame 300 may be disposed below the rotor 200 inside the inner frame 100 and may pass a fraction of a certain size or less into the crushed e-waste.

The outer frame 400 may surround the inner frame 100 and be disposed apart from the bottom of the inner frame 100. That is, a space may be formed between the outer frame 400 and the inner frame 100.

Particularly, by securing a space between the inner frame 100 and the outer frame 400, the impact noise generated when the electronic waste is crushed can be drastically reduced, and particularly, the shock noise can be prevented from diffusing to the outside have.

Both ends of the connector frame 500 may be installed in the inner frame 100 and the outer frame 400, respectively. As shown in FIG. 3, the connector frame 500 may have a plurality of disks 510 arranged at unequal intervals, and resonance holes 520 formed in the plurality of disks 510, respectively.

Noise can be understood in the same way as vibration, and vibrational energy has the property of being transmitted or diffused while vibrating the substance, and being reflected when it touches the surface of the substance. By arranging the plurality of disks 510 at unequal intervals, it is possible to expect the effect that the noise energy is dispersed by causing irregular reflection in an arbitrary direction without being concentrated when the noise is reflected, thereby reducing the noise energy.

That is, the impact noise can be remarkably attenuated significantly in the process of passing through the connector frame 500.

Meanwhile, the crushing apparatus for recycling electronic waste according to an embodiment of the present invention may be formed in a position or size when the resonance holes 520 are formed in the plurality of disks 510, respectively.

As a result, when the vibration energy is incident in the form of a wave, some wavelengths pass through and a portion of the vibration energy diffuses to disperse the noise energy, thereby reducing the noise.
