[0001] The utility model relates to an auxiliary device, in particular to an auxiliary device for melting lead. Background Art

[0002] Lead, as an important raw material, plays a key role in the manufacture of storage batteries, cables, and other industrial products. In industries such as storage battery manufacturing, cable manufacturing, and machinery manufacturing, the process of heating and melting lead is often involved. However, traditional lead melting auxiliary devices have some obvious limitations, which affect production efficiency and product quality.

[0003] Traditional lead melting auxiliary devices usually heat lead blocks by directly delivering flames to the bottom of the inner tank. This method has the following problems:

[0004] 1. Uneven heating: Due to uneven flame distribution, there is a temperature difference in the heating area at the bottom of the inner tank, which affects the quality of the lead liquid.

[0005] 2. Local overheating: Uneven heating leads to local overheating, increasing the formation of oxidation and impurities, thus affecting the performance of the final product.

[0006] 3. Lack of automatic temperature control: Most traditional devices do not have an automatic temperature control function, and manual monitoring and temperature adjustment are required frequently, which is time-consuming and laborious.

[0007] 4. Large temperature fluctuations: It is difficult to precisely control the temperature manually, easily resulting in excessive temperature fluctuations, which affect the quality and consistency of the lead liquid.

[0008] Based on this, in order to solve the above-mentioned technical defects, a lead melting auxiliary device that can improve heating uniformity and achieve automatic temperature control is proposed. Summary of the Utility Model

[0009] In order to overcome the shortcomings of traditional auxiliary devices, such as uneven flame distribution and the need for manual regulation due to the lack of an automatic temperature control function, which is time-consuming and laborious, the technical problem is: to provide an auxiliary device for melting lead.

[0010] The technical solution is: an auxiliary device for melting lead, including a melting furnace main body, a burner housing, a combustion assembly, a burner outlet pipe, a boiler inner tank, a combustion inner tank, and a ventilation pipe.

The burner housing is provided with a combustion assembly.

[0011] Furthermore, the burner housing forms an angle of 20° with the main body of the smelting furnace.

[0012] Furthermore, the combustion assembly includes a pressure gauge, a pressure reducing valve, a solenoid valve, a gas pipeline, a burner switch, a blower device, a controller, and a burner body. The top of the burner housing is connected to the gas pipeline. The solenoid valve is installed on the upper side of the gas pipeline, the pressure reducing valve is installed on the lower side of the gas pipeline, the pressure gauge is installed at a position near the solenoid valve on the gas pipeline, the burner switch is installed in the right part of the burner housing, the controller is installed on the burner switch, the blower device is installed at the lower left part of the burner housing, and the burner body is installed at the upper left part of the burner housing. The pressure gauge, the pressure reducing valve, the solenoid valve, the burner switch, the blower device, and the burner body are all electrically connected to the controller.

[0013] Furthermore, it further includes a smoke exhaust hood and a chimney. The top of the main body of the smelting furnace is connected to the smoke exhaust hood, and the front side of the top of the main body of the smelting furnace is connected to the chimney.

[0014] Furthermore, it further includes a conveying roller track. A conveying roller track for feeding is arranged on the right side of the top of the main body of the smelting furnace, and the conveying roller track penetrates through the smoke exhaust hood.

[0015] Furthermore, the bottom of the main body of the smelting furnace is provided with feet for adjusting the horizontal state of the main body of the smelting furnace.

[0016] The beneficial effects are as follows: 1. Through the specific angle design formed between the burner housing and the main body of the smelting furnace, the flame forms a cyclone shape in the chamber, which helps to improve the heating uniformity, reduces the quality problems of the lead liquid caused by local overheating, and when the lead in the boiler inner tank reaches the predetermined temperature, the system will automatically adjust the flame size to maintain the temperature of the lead liquid within a constant range, avoiding energy waste and unstable product quality caused by too high or too low temperature.

[0017] 2. Through the settings of the pressure gauge and the pressure reducing valve, the pressure of the natural gas can be monitored to ensure the stable gas pressure entering the burner body.

The burner housing 30 is installed on the right side of the main body 2 of the smelting furnace by bolts, and the burner housing 30 forms an angle of 20° with the main body 2 of the smelting furnace. The left side of the burner housing 30 is connected and communicated with the burner gas outlet pipe 39. The combustion inner liner 7 is connected inside the main body 2 of the smelting furnace, and the boiler inner liner 6 is connected at a position inside the main body 2 of the smelting furnace and on the inner side of the combustion inner liner 7. There is a chamber between the combustion inner liner 7 and the boiler inner liner 6. The right side of the combustion inner liner 7 is connected and communicated with the ventilation pipe 8, and the ventilation pipe 8 is connected with the burner gas outlet pipe 39. A combustion assembly is provided on the burner housing 30.

[0027] As Figures 5-6As shown, the combustion assembly includes a pressure gauge 31, a pressure reducing valve 32, a solenoid valve 33, a gas pipeline 34, a burner switch 35, a blower device 36, a controller 37, and a burner body 38. The top of the burner housing 30 is connected to the gas pipeline 34. The solenoid valve 33 is installed on the upper side of the gas pipeline 34 by bolts. The pressure reducing valve 32 is installed on the lower side of the gas pipeline 34. A pressure gauge 31 for monitoring the natural gas pressure is installed at a position on the gas pipeline 34 near the solenoid valve 33. A burner switch 35 is installed in the right part of the burner housing 30. The controller 37 is installed on the burner switch 35. A blower device 36 is installed at the lower left part of the burner housing 30. The blower device 36 is used to provide sufficient air to support combustion. A burner body 38 for igniting the mixture of natural gas and air is installed at the upper left part of the burner housing 30. The pressure gauge 31, the pressure reducing valve 32, the solenoid valve 33, the burner switch 35, the blower device 36, and the burner body 38 are all electrically connected to the controller 37. The bottom of the melting furnace main body 2 is provided with feet for adjusting the horizontal state of the melting furnace main body 2 and also playing a role in isolating vibration.

[0028] As Figure 1 shown, it further includes a conveying roller path 4, a smoke exhaust hood 1, and a chimney 5. The smoke exhaust hood 1 is welded to the top of the melting furnace main body 2. The chimney 5 is connected to the front side of the top of the melting furnace main body 2. A conveying roller path 4 for feeding is arranged on the right side of the top of the melting furnace main body 2. The conveying roller path 4 penetrates through the smoke exhaust hood 1.

[0029] When heating and melting lead, first convey the lead to the inner boiler liner 6 through the conveying raceway 4. After adding an appropriate amount of lead, connect the end of the gas pipeline 34 to the gas tank, turn on the burner switch 35, and the controller 37 controls the opening of the burner body 38. The system is ready. Adjust the pressure of natural gas through the pressure reducing valve 32 to ensure that the gas pressure entering the burner body 38 is appropriate. Subsequently, open the solenoid valve 33 to allow natural gas to enter the burner body 38 through the gas pipeline 34.

The pressure gauge 31 monitors the pressure of natural gas to ensure stable combustion. The controller 37 automatically adjusts the opening degree of the solenoid valve 33 according to the set temperature to control the flow rate of natural gas, thereby adjusting the flame size. The flame generated by the burner body 38 is conveyed to the ventilation pipe 8 through the burner outlet pipe 39, and then enters the chamber between the combustion inner liner 7 and the inner boiler liner 6. The specific angle formed between the burner housing 30 and the main body of the smelting furnace 2 causes the flame to form a cyclone shape in the chamber to heat the lead in the inner boiler liner 6 and gradually melt the lead. The smoke exhaust hood 1 can effectively capture the flue gas and steam generated during the melting of lead. The function of the chimney 5 is to serve as a passage for discharging the collected flue gas into the atmosphere. The settings of the smoke exhaust hood 1 and the chimney 5 can ensure the effective capture and discharge of flue gas. When the lead in the inner boiler liner 6 reaches the preset temperature, the controller 37 automatically adjusts the flame size to keep the temperature of the lead liquid stable. Then, the worker can use a ladle to take out the lead liquid from the inner boiler liner 6 for pouring operations, or convey the lead liquid to other equipment or molds for use through a pump set. When stopping heating, turn off the power supply of this device.
