[0030] More specifically:

[0031] like Figures 1-4 As shown:

[0032] In combination with the above content: the lower surface of the insulating plate 3 104 is fixedly mounted with the box 109, and the upper surface of the insulating plate 4 105 is fixedly mounted with the box 2 110;

[0033] A high-frequency magnetic induction coil 107 and a medium-frequency magnetic induction coil 108 are installed on the surface of the copper crucible body 106;

[0034] A water inlet and a water outlet are longitudinally arranged inside the side wall petals on the copper crucible body 106. A long cooling pipe 2 113 is fixedly connected to the side wall petals at the water inlet position, and a short cooling pipe 2 114 is fixedly connected to the side wall petals at the water outlet position. A cooling chamber is provided at the bottom of the copper crucible body 106. The cooling chamber of the copper crucible body 106 is respectively fixedly connected to a long cooling pipe 111 and a short cooling pipe 1 112. One end of multiple groups of long cooling pipe 2 113 and long cooling pipe 1 111 passes through box 1 109 and extends into the interior of box 2 110. One end of multiple groups of short cooling pipe 2 114 and short cooling pipe 1 112 extends into box 1 109.

[0035] The second box 110 is provided with a temperature sensor 117 , and the detection end of the temperature sensor 117 is provided inside the second box 110 ;

[0036] A water pump 119 is provided on one side of the first box 109. A delivery pipe 120 is fixed to the input end of the water pump 119. A delivery pipe 2 121 is fixed to the output end of the water pump 119. The other end of the delivery pipe 120 is fixed to and connected to the first box 109. The other end of the delivery pipe 2 121 is fixed to and connected to the top of the second box 110. A U-shaped frame 118 is fixed between the third insulating plate 104 and the fourth insulating plate 105. The water pump 119 is fixedly mounted on the side wall of the U-shaped frame 118. A control system module is installed on one side of the U-shaped frame 118.

[0037] Multiple sets of heat exchangers 124 are provided on the outside of the second box 110. A cooling fan 125 is provided on one side of the heat exchanger 124. A frame 123 is fixedly mounted on the surface of the second box 110 near the heat exchanger 124. The heat exchanger 124 is fixedly mounted on the surface of the frame 123. The cooling surface of the heat exchanger 124 is in contact with the surface of the second box 110. The cooling fan 125 is fixedly mounted on the surface of the frame 123. The cooling fan 125 corresponds to the heating surface of the heat exchanger 124.

[0038] A connecting pipe 115 is fixedly connected between the box body 109 and the box body 2 110 , and an electromagnetic control valve 116 is installed in the connecting pipe 115 .

[0039] In this embodiment, the magnetic induction coil-based float melting water-cooled copper crucible, when in use, uses the high-frequency magnetic induction coil 107 and the medium-frequency magnetic induction coil 108 to heat the material inside the copper crucible body 106. Two sets of high-frequency magnetic induction coils 107 and medium-frequency magnetic induction coils 108 are provided on the outside of the copper crucible body 106. The high-frequency magnetic induction coils 107 and the medium-frequency magnetic induction coils 108 are provided with different numbers of turns according to the height of the copper crucible body 106.

[0040] For example, a total of 14 turns are provided, including 8 turns of the high-frequency coil and 6 turns of the medium-frequency coil. The frequency of the high-frequency magnetic induction coil 107 is 20kHz-30kHz, and the frequency of the medium-frequency magnetic induction coil 108 is 2kHz-3kHz. The high-frequency magnetic induction coil 107 primarily performs a high-temperature melting function during the magnetic induction melting process, while the medium-frequency magnetic induction coil 108 performs a stirring function during the magnetic induction melting process. The medium-frequency magnetic induction coil 108 is positioned near the bottom wall of the copper crucible body 106. The height of the fourth turn of the medium-frequency magnetic induction coil 108 from top to bottom corresponds to the upper edge of the highest position of the bottom wall of the copper crucible body 106. Therefore, when the bottom wall of the copper crucible body 106 moves to the highest position, at least two turns of the medium-frequency magnetic induction coil 108 are still able to stir the molten material within the melting chamber.

[0041] When the copper crucible body 106 is cooled, the water pump 119 is started, and the water pump 119 extracts the cooling water from the inside of the box 109 through the delivery pipe 120, and delivers it to the inside of the box 2 110 through the delivery pipe 2 121. As the cooling water is continuously delivered to the box 2 110, the cooling water inside the box 2 110 is delivered to the water inlet hole of the side wall flap of the copper crucible body 106 through the long cooling pipe 2 113. Then, the cooling water enters the water outlet hole of the side wall flap through the water inlet hole of the side wall flap and is discharged into the short cooling pipe 2 114. Then, it is discharged to the inside of the box 109 through the short cooling pipe 2 114. Through this operation, the copper crucible body 106 is cooled.

[0042] During this process, the temperature sensor 117 accurately detects the temperature of the cooling water inside the second box 110. The heat exchanger 124 absorbs the heat of the water in the second box 110 through the circulation of the refrigerant, thereby reducing the water temperature. The cooling fan 125 helps the heat exchanger 124 dissipate heat to ensure that the temperature of the heat exchanger 124 does not become too high, thereby maintaining its working efficiency.

[0043] The temperature sensor 117 monitors the temperature of the water in the second box 110 in real time and feeds the data back to the control system module. The control system module sets the required cooling water temperature inside the second box 110. The control system module compares the actual temperature with the target temperature. If the actual temperature is higher than the target temperature, the control system module activates the heat exchanger 124 to start cooling. If the actual temperature is lower than or close to the target temperature, the control system module adjusts or cuts off the current through the heat exchanger 124 to stop or reduce heat absorption and prevent the water temperature from being too low.

[0044] At the same time, the control system module controls the electromagnetic control valve 116 to open. At this time, the cooling water inside the box 109 will enter the box 2 110 through the connecting pipe 115, and neutralize with the cooling water inside the box 2 110 (the cooling water inside the long cooling pipe 111 is higher than the cooling water inside the box 2 110 because it comes out of the copper crucible body 106). The cooling water inside the box 2 110 can be raised to a certain temperature;

[0045] Through this operation, the temperature of the cooling water inside the second box 110 can be adjusted. By accurately controlling the cooling water temperature, the temperature inside the copper crucible body 106 can be kept stable during the smelting process, avoiding rapid temperature changes that may cause thermal shock, and large temperature differences that may cause damage to the copper crucible body 106 material, thereby improving the use effect of this device.

[0046] It should be noted that the long cooling pipe 2 113 and the long cooling pipe 1 111 are sealed and fixed to the connection between the box 1 109 and the box 2 110 respectively. The long cooling pipe 2 113 and the long cooling pipe 1 111 are provided with a heat insulation sleeve at the position of the box 109. When the coolant passes through the box 109, it is not affected by the cooling water temperature inside the box 109.

[0047] The short cooling pipe 2 114 and the short cooling pipe 1 112 are connected to the box body 109 in a sealed and fixed manner.

[0048] Going further;

[0049] In an optional embodiment, a stirring rod 122 for stirring the cooling water is provided inside the second box 110, and a driving mechanism 2 for driving the stirring rod 122 to rotate is installed at the bottom of the second box 110;

[0050] The driving mechanism 2 includes a motor 201 fixed to the lower surface of the second box body 110, a bevel gear 1 202 fixed to the output end of the motor 201, and a bevel gear 2 203 meshingly connected to the surface of the bevel gear 1 202;

[0051] A rotating rod is fixedly installed at the inner center of the second bevel gear 203 by screws, and the stirring rod 122 is fixed to the top end of the rotating rod. The rotating rod is rotatably connected to the second box body 110 through a sealed bearing.

[0052] In this embodiment: when the cooling water inside box body 109 is transported to box body 2 110 through water pump 119, motor 201 is started, thereby driving bevel gear 1 202 to rotate. Since bevel gear 1 202 and bevel gear 2 203 are meshed and connected, bevel gear 2 203 is driven to rotate. Bevel gear 2 203 drives the rotating rod to rotate, and the rotating rod drives the stirring rod 122 to rotate, which can stir the cooling water, thereby making the neutralized cooling water temperature more uniform.

[0053] The working principle and use process of the present invention are as follows: when the floating melting water-cooled copper crucible based on the magnetic induction coil is in use, when the copper crucible body 106 is cooled, the water pump 119 is started, and the water pump 119 extracts the cooling water inside the box body 109 through the delivery pipe 120, and delivers it to the box body 2 110 through the delivery pipe 2 121. As the cooling water is continuously delivered to the box body 2 110, the cooling water inside the box body 2 110 is delivered to the side wall petal water inlet hole of the copper crucible body 106 through the long cooling pipe 2 113, and then the cooling water enters the side wall petal water outlet hole through the side wall petal water inlet hole, and is discharged to the short cooling pipe 2 114, and is discharged through the short cooling pipe 2 The cooling water in the second box 110 is discharged to the interior of the first box 109 by the second cooling pipe 114. Through this operation, the copper crucible body 106 is cooled. In this process, the temperature of the cooling water in the second box 110 is accurately detected by the temperature sensor 117. The heat exchanger 124 absorbs the heat of the water in the second box 110 through the circulation of the refrigerant, thereby reducing the water temperature. The cooling fan 125 helps the heat exchanger 124 to dissipate heat, ensuring that the temperature of the heat exchanger 124 is not too high and maintaining its working efficiency. The temperature sensor 117 monitors the temperature of the water in the second box 110 in real time and feeds back the data to the control system module. The control system module sets the required temperature of the second box 110. 0 internal cooling water temperature, the control system module compares the actual temperature with the target temperature. If the actual temperature is higher than the target temperature, the control system module will activate the heat exchanger and start cooling. If the actual temperature is lower than or close to the target temperature, the control system module will adjust or cut off the current through the heat exchanger 124 to stop or reduce heat absorption to prevent the water temperature from being too low. At the same time, the control system module controls the electromagnetic control valve 116 to open. At this time, the cooling water inside the box 109 will enter the inside of the box 2 110 through the connecting pipe 115 and be neutralized with the cooling water inside the box 2 110 (the cooling water inside the long cooling pipe 111 is cooled by the cooling water from the copper crucible body 106). Out, so that the cooling water inside the long cooling tube 111 is higher than the cooling water temperature inside the box body 2 110), and the cooling water inside the box body 2 110 can be raised to a certain temperature; when the cooling water inside the box body 109 is transported to the box body 2 110 through the water pump 119, the motor 201 is started, which drives the bevel gear 1 202 to rotate. Since the bevel gear 1 202 and the bevel gear 2 203 are engaged and connected, the bevel gear 2 203 is driven to rotate. The rotating rod is driven to rotate by the bevel gear 203, and the rotating rod drives the stirring rod 122 to rotate, which can stir the cooling water, thereby making the neutralized cooling water temperature more uniform.
