[0019] The structure of the utility model is further described below in conjunction with the accompanying drawings.

[0020] Reference Figures 1 to 3 The utility model of the electric precious metal special melting adsorption device includes a base 1, a melting cup 2 arranged on the base and a heating device 3 for heating the melting cup. The base 1 is provided with a bracket 4 and a melting cup seat 5 arranged on the bracket. The melting cup 2 is located in the melting cup seat 5. The melting cup seat is rotatably arranged on the bracket. The bracket is provided with a melting cup seat driving mechanism 6 for driving the melting cup seat to rotate. The two ends of the bracket are rotatably arranged on the base through a bracket rotating shaft 41. The bracket rotating shaft 41 includes a first rotating shaft 411 fixedly arranged on one side of the bracket. The base is provided with an electric driving mechanism 7 for driving the bracket to rotate on the base. The electric driving mechanism 7 includes a first motor 71, a driving gear 72, a transmission gear 73 and a chain 74. The driving gear is fixedly connected to the first motor main shaft, the transmission gear is fixedly arranged on the first rotating shaft, the first rotating shaft and the transmission gear are concentrically arranged, and the driving gear and the transmission gear are synchronously driven through a chain. During operation, the melting cup seat driving mechanism drives the melting cup to rotate while the heating device heats the melting cup, thereby quickly melting the precious metal in the melting cup. When molten metal hangs on the wall of the melting cup, the main shaft of the first motor rotates to drive the driving gear to rotate, and the driving gear synchronously drives the transmission gear to rotate through the chain. The transmission gear drives the first rotating shaft to rotate, thereby driving the bracket to rotate on the base, thereby tilting the melting cup at a certain angle. At this time, the melting cup tilts and rotates, and the metal hanging on the wall is adsorbed together, thereby reducing metal loss.

[0021] In this embodiment, the melting cup seat 5 is made of insulating material, and quartz material can be used to make the melting cup seat, and other insulating materials can also be used. The melting cup is made of conductive material. The heating device 3 is an induction coil wound around the outside of the electromagnetic melting cup seat. After the induction coil is connected to alternating current, an alternating magnetic field is generated inside it, and the conductor melting cup and the precious metal conductive material inside it generate a short-circuit current, thereby heating the melting cup and the precious metal, thereby achieving directional heating with high heating efficiency. In this embodiment, an insulating cup 8 is provided in the melting cup seat 5, and the melting cup is located in the insulating cup, and the insulating cup is a graphite cup. The thermal conductivity of graphite decreases with increasing temperature, and it can have a good insulation effect under high temperature conditions. The insulating cup separates the melting cup from other components to prevent the melting cup from overheating and damaging other adjacent components.

[0022] In this embodiment, an electrode 42 electrically connected to the induction coil is provided in the support shaft 41. The electrode is used to energize the induction coil, and a control panel 9 is provided on the base to control the on and off of the induction coil. The control panel also controls the start of the motor. When the support rotates, the induction coil, the electrode and the support shaft rotate together along the support shaft to prevent the induction coil from being torn off during the rotation. At the same time, the structure is simple and compact, and it is easy to install.

[0023] In this embodiment, the bracket 4 is a box structure, the melting cup seat is located in the box structure, the top of the box structure is provided with a first through hole 43 for the opening of the melting cup seat to be exposed, the bottom of the melting cup seat 5 is provided with a melting cup seat rotating shaft 51, and the bottom of the box structure is provided with a second through hole 44, and the melting cup seat rotating shaft is rotatably connected to the bracket through a bearing 45 provided at the second through hole. Thus, the overall mechanism is simple and compact, and is easy to install and use. In this embodiment, the melting cup seat driving mechanism 6 is a second motor, and the second motor main shaft is connected to the melting cup seat rotating shaft through a pulley 61. The motor drives the melting cup seat rotating shaft to rotate through the pulley, thereby driving the melting cup seat to rotate.

[0024] In this embodiment, a first cavity 11 is provided on the base 1, and the first cavity is open at the top. The bracket shaft 41 also includes a second shaft 412 fixed on the bracket. The first shaft and the second shaft are respectively located on both sides of the bracket. The first sleeve 111 and the second sleeve 112 are respectively provided on the two side walls of the first cavity 11, and at least one of the first sleeve and the second sleeve has a damping sleeve 113 inside. In this embodiment, a damping sleeve is provided in the first sleeve. In specific implementation, a damping sleeve can be provided in both the first sleeve and the second sleeve, or a damping sleeve can be provided in the second sleeve. The damping sleeve can prevent the bracket shaft from shaking when it stops rotating. It can keep the bracket from rotating at a certain angle. The bracket is hollow around to prevent the bracket from colliding with other components when it rotates, and it is also beneficial to the heat dissipation of the bracket. A first heat dissipation hole 46 is provided on the side wall 4 of the bracket. The first heat dissipation hole is beneficial to the heat dissipation of the bracket.

[0025] In this embodiment, a heat sink 8 is further provided in the base 1, and a second heat sink 12 is provided on the side wall of the base 1, and the second heat sink is provided corresponding to the heat sink. The heat sink can be provided as a fan, which is fixed to the side wall of the base by screws, and the control panel controls the opening of the fan. The heat sink can dissipate the heat in the base to prevent the temperature in the base from being too high and damaging the components in the base.

[0026] Although the specific implementation of the utility model is described in detail in conjunction with the drawings, it should not be understood as limiting the protection scope of the utility model. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still belong to the protection scope of the utility model.
