[0048] A clean and environmentally friendly tin recovery method, the method comprising the following steps:

[0049] Collecting tin slag: the servo drive mechanism drives the rotating frame 23 to rotate to a position where the heat-conducting sleeve 32 is directly opposite to the slag removal port 11, the telescopic drive member 26 drives the heat-conducting sleeve 32 to move through the slag removal port 11 into the smelting furnace 10, the lifting drive member 25 drives the lifting frame 22 and the heat-conducting sleeve 32 to move downward until the heat-conducting sleeve 32 contacts the slag in the smelting furnace 10, the heat-conducting sleeve 32 absorbs heat to cool and solidify the slag and then adheres to the heat-conducting sleeve 32, the lifting drive member 25 drives the lifting frame 22 and the heat-conducting sleeve 32 to move upward, and the telescopic drive member 26 drives the heat-conducting sleeve 32 to move to the outside of the smelting furnace 10;

[0050] Cutting tin slag: the servo drive mechanism drives the rotating shoulder to rotate to the position where the heat-conducting sleeve 32 and the cutting mechanism are opposite, and the translation drive member 53 drives the movable frame 52 and the cutting mechanism to move toward the heat-conducting sleeve 32, so that the cutting mechanism contacts the tin slag. After the cutting mechanism cuts the tin slag, the tin slag falls onto the guide plate 61, and the tin slag rolls along the guide plate 61 to the first conveyor belt 62;

[0051] Crushing tin slag: The first conveyor belt 62 conveys the tin slag to the crusher 60, and the crusher 60 crushes the tin slag and then conveys it to the second conveyor belt 63;

[0052] Tin recovery: The second conveyor belt 63 conveys the tin slag to the feed port 12 of the smelting furnace 10, and the smelting furnace 10 melts the tin slag.

[0053] This embodiment has the following advantages:

[0054] Tin slag contains molten tin. Since tin will adhere to the tin slag, directly removing the tin slag will cause the tin attached to the tin slag to be removed at the same time. The present invention absorbs the heat of the tin attached to the tin slag after the heat-conducting sleeve 32 contacts the tin slag, so that the tin is cooled and solidified and adheres to the heat-conducting sleeve 32, so that the tin slag can be moved to the outside of the smelting furnace 10 with the heat-conducting sleeve 32, and the function of collecting the tin slag is realized. At this time, the tin slag in the smelting furnace 10 can be reduced, which is conducive to the production of higher quality tin products. After the heat-conducting sleeve 32 moves toward the cutting mechanism, the movable frame 52 drives the cutting mechanism to move, so that the cutting mechanism abuts against the tin slag and cuts off the tin slag from the heat-conducting sleeve 32, and then the tin slag is transported to the crusher 60 through the first conveyor belt 62 for crushing, and then the tin slag is transported to the smelting furnace 10 for re-smelting through the second conveyor belt 63, so as to realize the recovery of tin. In the process of recovering tin, no waste liquid pollution will be generated, the impact on the environment is small, the impact on the environment is small, it is beneficial to environmental protection, and the advantages of clean and environmental protection are achieved.

[0055] The rotation center of the connecting frame 31 is moved to the center position of the smelting furnace 10 , so that the connecting frame 31 can drive the heat-conducting sleeve 32 to rotate 360°, thereby being able to fully collect the tin slag in the smelting furnace 10 .

[0056] When the heat-conducting sleeve 32 contacts the tin slag, the air pump 41 supplies air to the connecting hole 43 through the air supply pipe 42, and the connecting hole 43 injects air into the connecting hole 43 through the semi-lunar air inlet groove 44, and the air in the connecting hole 43 is discharged through the semi-lunar exhaust groove 45, so that the air in the cooling section 47 flows. The air flowing in the cooling section 47 dissipates heat and cools the connecting frame 31 and the heat-conducting sleeve 32, ensuring that the heat-conducting sleeve 32 can continuously absorb the heat of the tin slag, thereby ensuring that the tin slag can be stably bonded to the heat-conducting sleeve 32.

[0057] When the connecting frame 31 rotates, the semi-lunar air inlet groove 44 and the semi-lunar air exhaust groove 45 whose arc center is located on the rotation axis of the connecting frame 31 can maintain a state of communication with the first air hole 48 and the second air hole 49, so as to continuously dissipate heat and cool the connecting frame 31 and the heat conductive sleeve 32.

[0058] When the heat-conducting sleeve 32 contacts with the tin slag, the clamping plate 33 can be inserted into the tin slag. When the heat-conducting sleeve 32 moves with the rotation of the connecting frame 31, the clamping plate 33 encounters greater resistance. Therefore, the clamping plate 33 can rotate due to the resistance of the tin slag. The heat-conducting sleeve 32 is driven to rotate by the clamping plate 33, so that the surfaces of different positions of the heat-conducting sleeve 32 can contact with the tin slag, so that more tin slag can be collected through the heat-conducting sleeve 32.

[0059] The movable frame 52 drives the inserting knife 54 to move toward the heat conducting sleeve 32 , and the inserting knife 54 is inserted between the tin slag and the heat conducting sleeve 32 , so that the tin slag can be cut off from the heat conducting sleeve 32 by the inserting knife 54 , thereby realizing the function of cutting off the tin slag on the heat conducting sleeve 32 by the cutting mechanism.

[0060] When the heat-conducting sleeve 32 moves to above the guide plate 61, the electric heating plate 34 heats the connecting frame 31 and the heat-conducting sleeve 32, so that the tin slag is heated by the heat-conducting sleeve 32. The tin slag melts again after the temperature rises, thereby reducing the resistance encountered by the insert 54 when cutting the tin slag, ensuring that the tin slag can be cut off by the cutting mechanism.

[0061] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the invention.
