Description

TECHNICAL FIELD

[0002] Smelting furnace uses 200-2500Hz intermediate frequency power supply to carry out induction heating, and the power range is 20-2500KW, and it can also be called intermediate frequency electric furnace according to its characteristics, and it is mainly used for the smelting and temperature raising of noble metals such as gold, platinum, silver, copper, iron, stainless steel, aluminum alloy, aluminum and other metals, and the smelting temperature of different metals is different, so the temperature in the smelting furnace needs to be adjusted according to the smelting temperature of different metals by temperature control device.

[0003] The existing temperature control device has the following defects in use process:

[0004] 1. In the application process of the existing temperature control device, the smelting temperature of the smelting furnace is usually adjusted by controlling the heating switch of the smelting furnace. When the temperature is too high, the heating temperature gradually decreases with the rotation of the heating switch, so that the internal temperature of the smelting furnace decreases. However, due to the high temperature of the smelting furnace before adjustment, the internal temperature of the smelting furnace rapidly decreases to the smelting temperature of the metal, so that it takes a long time to restore the smelting furnace temperature to the normal range of the smelting temperature of the metal, which easily causes excessive smelting of the metal and affects the smelting quality of the metal.

[0005] 2. When the temperature of the smelting furnace is too high, the furnace cover is usually opened to make the external gas enter the internal smelting furnace, so as to form air flow, and at the same time, the heating switch is adjusted, so that the temperature of the smelting furnace can be better controlled by combining the two ways of adjusting the heating switch and air flow. However, this method will increase the temperature around the smelting furnace in the application process, which is not conducive to the heat dissipation of the electrical appliances or other equipment around the smelting furnace, and at the same time, it provides a smelting environment with very low comfort for the user, which is not conducive to the user to smelt the metal.

[0036] As shown in Figures 1 to 5 When the temperature inside the smelting furnace body 1 is too high, at this time the temperature sensor 2 transmits a signal to the controller, at this time the controller compares the temperature signal transmitted by the temperature sensor 2 with the initially set threshold range, if the temperature signal transmitted by the temperature sensor 2 is higher than the set threshold range, the controller controls the motor to start, so that the motor starts to work, the output shaft of the motor drives the mounting seat 31 to rotate counterclockwise, the mounting seat 31 drives the three-way valve 33 to rotate counterclockwise when rotating counterclockwise, and the rotating angle is 90 degrees, and the original three-way valve 33 is communicated with the cold pipe 35 to drive the outlet to be communicated with the conveying pipe 36 at this time, and the other outlet in the original closed state is communicated with the cold pipe 35, the cold air in the cold pipe 35 enters the conveying pipe 36 through the three-way valve 33, the cold air enters the pipe 37 from the inside of the conveying pipe 36, and the cold air enters the temperature control cavity 4 from the inside of the pipe 37, so as to cool the inside of the temperature control cavity 4, so that the temperature of the inner wall of the smelting furnace body 1 is reduced through the temperature inside the temperature control cavity 4, and the temperature inside the smelting furnace body 1 is controlled for the first time, and after the cold air enters the temperature control cavity 4, the cold air gradually enters the smelting furnace body 1 with the continuous introduction of the cold air, so that the cold air directly cools the temperature inside the smelting furnace body 1, thereby controlling the temperature inside the smelting furnace body 1 for the second time, so that the surrounding environment of the smelting furnace body 1 is not affected when the temperature inside the smelting furnace body 1 is controlled, which is conducive to the normal operation of other equipment around the smelting furnace body 1, and at the same time, the time for controlling the temperature of the inner wall of the smelting furnace body 1 is shortened, so that the temperature inside the smelting furnace body 1 can quickly reach the range of the smelting temperature of the metal, and the smelting quality of the metal is improved;
