SPECIFIC GRAVITY SEPARATING APPARATUS FOR WET WASTED FISH NET USING SPECIFIC GRAVITY DIFFERENCE

The present invention relates to a specific gravity separating apparatus of a waste fishing net and, more specifically, to a wet specific gravity separating apparatus of a waste fishing net using a specific gravity difference, which separates waste fishing nets into high specific gravity substances and low specific gravity substances by using a specific gravity difference. The wet specific gravity separating apparatus of a waste fishing net using a specific gravity difference according to the present invention comprises: a fishing net input unit (10) that accommodates pulverized and inputted waste fishing nets and moves the same downward while agitating the same; a water tank unit (20) that accommodates a specific gravity liquid and the pulverized waste fishing nets inputted from the fishing net input unit (10) in a body part of a hollow structure with an open upper surface; a first transfer paddle (21) that is installed at an upper end of the water tank unit (20), immerses the inputted waste fishing nets under a water surface, and rotates at the same time to transfer the same in a rotational direction; a second transfer paddle (22) that is provided in a shape of a plurality of wings and transfers a low specific gravity material lighter than the specific gravity liquid and floating in the water tank unit (20) among the waste fishing nets transferred by the first transfer paddle (21); a low specific gravity material discharge unit (30) that recovers the low specific gravity material; an inclined plate (23) that collects a high specific gravity material heavier than the specific gravity liquid among the waste fishing nets settled by the second transfer paddle (22) to a lower part of the water tank unit (20); and a high specific gravity material discharge unit (40) that transfers and recovers the high specific gravity material recovered at the lower part of the water tank unit (20) by the inclined plate (23), wherein the specific gravity liquid is an aqueous sodium chloride solution having a specific gravity of 1.2 g/cm^3 or industrial water having a specific gravity of 1.0 g/cm^3. The apparatus has improved efficiency of wet specific gravity separation. 본 발명은 폐어망 비중 분리 장치에 관한 것으로, 더욱 상세하게는 비중 차이를 이용하여 폐어망을 고비중 물질 및 저비중 물질로 분리하는 비중 차를 이용한 폐어망 습식 비중 분리 장치에 관한 것이다. 본 발명에 따른 비중 차를 이용한 폐어망 습식 비중 분리 장치는, 분쇄되어 투입되는 폐어망을 수용하여 아래로 이동시키면서 교반하는 어망투입부(10); 상부면이 개방된 중공 구조의 몸체부에 비중액과 상기 어망투입부(10)에서 유입되는 분쇄 폐어망을 수용하는 수조부(20); 상기 수조부(20) 상단에 설치되어 회전과 동시에 투입되는 폐어망을 수면 아래로 담가
