[0002] At present, the research on marine waste treatment is also quite popular, but it is mostly focused on how to collect marine waste. The research on the sorting and treatment of marine waste is rarely involved. Only a few documents mention that the collected waste should be crushed and drained to reduce the volume and weight of the waste. However, when there are too many different types of waste, it will also bring inconvenience to the next step of waste treatment. At present, the research on the sorting of domestic waste is also based on vision and manipulators for waste sorting, which is difficult to apply to large-scale production, especially for the sorting of waste on ships.

[0018] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments. Those skilled in the art should know that the following embodiments are not the only limitations on the technical solutions of the present invention, and any equivalent changes or modifications made within the spirit of the technical solutions of the present invention should be deemed to fall within the protection scope of the present invention.

[0019] Tangible garbage on the sea surface mainly includes plastics, foam, glass, ceramics, wood products, etc. Generally speaking, in order to facilitate the collection of the above garbage, the salvaged garbage is crushed and pre-processed in advance. The utility model proposes a marine garbage sorting system, which further classifies and separates the crushed mixed garbage.

[0020] The sorting system proposed by the utility model is made by adopting the principles of electrostatic separation and water separation. By utilizing the electrostatic adsorption characteristics, the electrostatic separation method is mainly used to separate plastics and foams from glass, ceramics, and wooden products; secondly, the plastics and foams are separated by a water separation method by utilizing the different specific gravities and different sedimentation levels in water; for glass, ceramics, and wood, the water separation method is adopted by utilizing the different specific gravities and different sedimentation levels in water to separate them.

[0021] Therefore, if Figure 1 , Figure 2 As shown, the system configuration of the utility model includes: a mixed material electrostatic separation mechanism, a first group of water separation mechanisms, and a second group of water separation mechanisms.

[0022] The mixed material electrostatic separation mechanism comprises a mixed material hopper 1, an auger 2, a motor 3, a mixed material flattening roller 4, a mixed material electrostatic conveyor belt 5, a static generating conveyor belt roller 6, and a static removing brush 7. The mixed material hopper 1, the auger 2, the motor 3, and the mixed material flattening roller 4 are installed on a frame, and are all located above the input end of the mixed material electrostatic conveyor belt 5, wherein the mixed material hopper 1 is located above the auger 2 and directly opposite to the auger feeding port, the auger 2 is driven by the motor 3, and the auger 2 is a bidirectional spiral auger; the mixed material flattening roller 4 is located in front of the auger, and is slightly higher than the upper surface of the mixed material electrostatic conveyor belt 5 by a certain distance. The working principle of the mixture hopper 1, auger 2, motor 3 and mixture flattening roller 4 is: the mixture hopper 1 feeds the auger 2 with materials that are crushed marine garbage mixture, the auger 2 is driven by the motor 3, and the bidirectional spiral blades on the auger push the crushed garbage from the middle to both sides, and then spread it on both sides of the conveyor belt, and then it is unfolded and flattened by the mixture flattening roller 4 and taken away by the mixture electrostatic conveyor belt 5, thereby completing the transportation of the mixture.

[0023] The mixed material electrostatic conveyor belt 5 and the electrostatic generating conveyor belt roller 6 are both made of rubber material that can generate static electricity. The two ends of the mixed material electrostatic conveyor belt 5 are supported by the electrostatic generating conveyor belt roller 6 for operation. The electrostatic generating conveyor belt roller 6 is a roller with an electrostatic generator, which functions to support and drive the conveyor belt and conduct static electricity to the conveyor belt. The electrostatic removal brush 7 is arranged below the mixed material electrostatic conveyor belt 5, and the brush contacts the surface of the conveyor belt. The working principle of electrostatic separation is: after the mixed material electrostatic conveyor belt 5 is charged with static electricity, the plastic and foam flattened on the conveyor belt are adsorbed and taken away, while materials such as broken wood and glass are not adsorbed by static electricity and will fall at the end of the conveyor belt; and the electrostatic removal brush 7 is arranged below the mixed material electrostatic conveyor belt 5. The function of the electrostatic removal brush 7 is to eliminate static electricity and brush off the foam and plastic on the conveyor belt. When the foam and plastic attracted by the conveyor belt run on the conveyor belt to the electrostatic removal brush 7, they fall into the plastic foam separation box below under the combined action of the electrostatic removal brush and gravity, thus completing the first garbage sorting, and separating plastic and foam from glass, ceramics, and wood.

[0024] The first group of water separation mechanisms and the second group of water separation mechanisms are arranged at the end and the bottom of the mixed material electrostatic separation mechanism. The two groups of separation mechanisms respectively complete the separation of different substances. The "first group" and the "second group" are only defined for distinction, and there is no actual distinction in level and order.

[0025] The first set of water separation mechanisms is connected to the conveying end of the mixed material electrostatic conveyor belt 5, the purpose is to further separate the wood chips and glass, including the wood chips and glass collection box 8, the wood chip conveyor belt 9, and the wood chip collection box 10. The wood chips and glass collection box 8 is placed in the front and lower part of the mixed material electrostatic conveyor belt 5, and receives the wood chips and glass that fall from the conveyor belt. The wood chips and glass collection box 8 is filled with water. When the crushed glass and wood chips enter the wood chips and glass collection box 8, the glass chips will sink to the bottom of the water due to their high density and remain in the wood chips and glass collection box 8 for preservation, while the wood chips will float on the water surface. One end of the wood chip conveyor belt 9 is set on the upper layer of water in the wood chips and glass collection box 8, and the other end extends obliquely upward outside the box. The wood chip conveyor belt 9 will bring the wood chips floating on the water surface to the wood chip collection box 10. Furthermore, the wood chip conveyor belt 9 is a metal mesh conveyor belt, which is used for drainage and does not generate static electricity.

[0026] The second set of water separation mechanisms is arranged below the mixed material electrostatic conveyor belt 5 to further separate the foam and plastic, and includes a plastic foam collection box 11, a plastic conveyor belt 12, a foam conveyor belt 13, a plastic collection box 14, and a foam collection box 15.

[0027] The plastic foam collection box 11 is also filled with water and is arranged directly below the mixed material electrostatic conveyor belt 5. The plastic and foam brushed off by the static removal brush 7 fall into the plastic foam collection box 11 below the mixed material electrostatic conveyor belt 5. The foam and plastic cleaned into the plastic foam collection box 11 are also divided into upper and lower layers in the water due to their different densities.

[0028] One end of the plastic conveyor belt 12 is arranged in the plastic foam collection box 11, and the other end extends obliquely upward out of the box. In addition, the plastic conveyor belt 12 is placed in the middle and lower layers of water in the plastic foam collection box and is completely below the mixed material electrostatic conveyor belt 5. It can catch the plastic brushed off the mixed material electrostatic conveyor belt 5 and bring the broken plastic into the plastic collection box 14.

[0029] One end of the foam conveyor belt 13 is also arranged in the plastic foam collection box 11, and the other end also extends obliquely upward out of the box. However, the foam conveyor belt 13 is placed in the middle and upper layers of the water in the plastic foam collection box, and on the outside of the mixed material electrostatic conveyor belt 5. The foam and plastic brushed off from the mixed material electrostatic conveyor belt 5 cannot fall directly on it, and can only take away the foam floating on the water surface. The conveying end of the foam conveyor belt 13 receives the foam collection box 15.

[0030] Furthermore, the plastic conveyor belt 12 and the foam conveyor belt 13 are respectively placed on both sides of the plastic foam collecting box 11 .

[0031] Furthermore, in the plastic foam collection box 11, a foam baffle 16 is installed near the side of the plastic conveyor belt 12, and the foam baffle 16 is used to prevent the foam floating on the water surface from being carried out by the plastic conveyor belt.

[0032] Furthermore, the plastic conveyor belt 12 and the foam conveyor belt 13 are also metal mesh conveyor belts, which are used for draining water and do not generate static electricity.

[0033] The first group of water separation mechanisms and the second group of water separation mechanisms mentioned above both utilize the water separation principle to separate wood chips and glass, and to separate plastics and foam, thereby completing the separation of several major types of garbage at sea.
