[0023] Example

[0024] See also Figure 1-Figure 4 The utility model provides a temperature control device for the bottom of a silicon-manganese furnace, comprising a bottom plate 100 and a temperature control component 200 .

[0025] Among them, the temperature control component 200 is installed on the surface of the base plate 100. Since the bottom of the induction furnace body 130 is close to the ventilation hole 120, the heat at the bottom of the induction furnace body 130 can be discharged from the ventilation hole 120 along with the cold air through the temperature control component 200, thereby reducing the possibility of the silicon manganese having a high temperature after heat treatment and needing to wait for the silicon manganese to cool naturally.

[0026] See also Figure 1-Figure 3 A support base 110 is installed on the surface of the bottom plate 100 , a ventilation hole 120 is opened on the surface of the support base 110 , and a mineral arc furnace body 130 is installed on the surface of the support base 110 , and a temperature sensor 140 is installed on the surface of the mineral arc furnace body 130 .

[0027] In the present embodiment, a plurality of ventilation holes 120 are provided, and the ventilation holes 120 are interconnected. In a specific implementation, a plurality of ventilation holes 120 are provided here, which is beneficial to improving the cooling effect of the bottom of the ore-heating furnace body 130; dustproof nets 121 are connected to the ventilation holes 120. In a specific implementation, dustproof nets 121 are connected to the ventilation holes 120 here, so as to reduce the possibility that dust from the outside will enter the ventilation holes 120; a heating chamber 150 is provided in the support seat 110, and a heating block 151 is connected to the heating chamber 150. In a specific implementation, by starting the heating block 151, the heat generated will accumulate in the heating chamber 150, which is beneficial to heating the bottom of the ore-heating furnace body 130. The heating block 151 is electrically connected to the temperature sensor 140. When the temperature sensor 140 detects that the temperature at the bottom of the ore-heating furnace body 130 is low, the signal will be transmitted to the heating block 151, so that the heating block 151 works, and the heating chamber 150 is connected to all ventilation holes 120.

[0028] See also Figure 1-Figure 4 The temperature control component 200 includes an air cooler 210 and an air duct group 220. The air cooler 210 is installed on the surface of the base plate 100, and the output end of the air cooler 210 is connected to the air duct group 220. The air duct group 220 is connected to one end of the ventilation hole 120. The temperature sensor 140 is electrically connected to the air cooler 210. In a specific implementation, when the temperature sensor 140 detects that the temperature at the bottom of the ore-heating furnace body 130 is too high, it will transmit a signal to the air cooler 210 to start the air cooler 210. The cold air from the outside will be transported to the ventilation hole 120 of the support seat 110 through the air duct group 220, which can accelerate the gas circulation in the ventilation hole 120, which is beneficial to cooling the bottom of the ore-heating furnace body 130, thereby achieving the effect of temperature control and reducing the possibility that the silicon manganese has a high temperature after heat treatment and needs to wait for the silicon manganese to cool naturally.

[0029] In this embodiment, a protective shell 160 is installed on the surface of the base plate 100, and the air cooler 210 is located in the protective shell 160. A through hole 161 is opened on the surface of the protective shell 160, and a plurality of through holes 161 are provided. In a specific implementation, the air cooler 210 is arranged in the protective shell 160, which is beneficial to protecting the air cooler 210. A plurality of through holes 161 are opened on the surface of the protective shell 160, which is beneficial to the circulation of gases; the air supply pipe group 220 includes a pipe body 221 and a connecting pipe 222, and the pipe body 221 is respectively connected to the output end of the air cooler 210 and the connecting pipe 222, and the connecting pipe 222 is connected to one of the ventilation holes 120.

[0030] A support frame 170 is installed on the surface of the base plate 100, and one end of the support frame 170 is sleeved on the surface of the tube body 221. In a specific implementation, the tube body 221 can be supported by the support frame 170, which is beneficial to the stability of the tube body 221 and the connecting pipe 222 on the device; a control valve 230 is arranged on the surface of the connecting pipe 222, and the control valve 230 is electrically connected to the temperature sensor 140. In a specific implementation, when the temperature sensor 140 detects that the temperature at the bottom of the electric arc furnace body 130 is high, the temperature sensor 140 will transmit a signal to the control valve 230, thereby adjusting the flow of cold air through the connecting pipe 222, so that the cold air enters the ventilation hole 120, which is beneficial to cooling the electric arc furnace body 130, thereby achieving the purpose of temperature control.

[0031] Specifically, the working principle of the temperature control device for the bottom of the silicon-manganese furnace body is as follows: when in use, when the temperature sensor 140 detects that the temperature at the bottom of the ore-heating furnace body 130 is low, it will transmit a signal to the heating block 151, so that the heating block 151 starts to work, and the heat generated will accumulate in the heating chamber 150, which is conducive to heating the ore-heating furnace body 130 and heat-treating the silicon-manganese in the ore-heating furnace body 130. When the temperature sensor 140 detects that the temperature at the bottom of the ore-heating furnace body 130 is high, it will transmit a signal to the heating block 151, so that the heating block 151 starts to work, and the heat generated will accumulate in the heating chamber 150, so as to heat the ore-heating furnace body 130 and heat-treat the silicon-manganese in the ore-heating furnace body 130. The air cooler 210 on the bottom plate 100 is turned on to start working. The air cooler 210 will transport cold air to the ventilation holes 120 of the support seat 110 through the pipe body 221 and the connecting pipe 222, thereby accelerating the circulation of air in the ventilation holes 120, which is beneficial for discharging the heat in the heating chamber 150 through the ventilation holes 120, thereby cooling the electric arc furnace body 130, achieving the effect of temperature control, and reducing the possibility of silicon manganese having a high temperature after heat treatment and needing to wait for natural cooling of silicon manganese.
