Description

Technical Field

[0001] This invention relates to the field of oxygen-enriched smelting technology, specifically to an automatic oxygen supply control device for oxygen-enriched smelting of copper-containing solid waste. Background Technology

[0002] In modern life, many electronic and electrical devices contain a large amount of copper. When these devices are discarded, their internal metal components are difficult to decompose. Therefore, the scientific treatment of these wastes has become a key issue. In existing technologies, oxygen-enriched smelting is generally used to separate the copper metal from copper-containing solid wastes. The copper can then be recycled and reused. This technology makes an important contribution to the beneficial recycling of waste.

[0003] In oxygen-enriched smelting equipment, the oxygen supply device plays a crucial role as an indispensable component. While existing oxygen supply devices in oxygen-enriched smelting equipment are simple in structure and can meet general usage requirements, they still have the following drawbacks in actual use:

[0004] 1. The oxygen supply device in the existing oxygen-enriched smelting equipment has a relatively simple oxygen supply process control, lacks a precise intelligent control part, and the manual control has a certain lag, which is not conducive to the control of the smelting process.

It cannot adjust the position of the outlet in a timely manner according to the amount of molten material and the height of the accumulation point. As a result, the oxygen supply reaches the smelting area slowly under high temperature and the coverage is insufficient. This prolongs the smelting time, increases the oxygen supply, and raises the smelting cost. Summary of the Invention

[0038] Working Principle: During operation, the total mass, stacking height, and stacking area of ​​the molten material in the melting furnace are first determined. The mass can be obtained by weighing, while the stacking height and stacking area can be measured using measuring tools. Based on the calculated data, the total amount of oxygen and air required for melting is determined, and the melting time is estimated. Then, the total amount of exhaust required by the exhaust hole 507 on the right end face of the exhaust plate 505 during the melting process is set. Based on the melting time, the gas flow rate and pressure at the outlet of the exhaust hole 507 are determined. Then, the gas flow rate and pressure in each pipe are calculated, and the adjustment threshold of the valves in each pipe is determined. The specific operation is as follows: Based on the melting point height in the melting furnace, the solenoid valve 509 at the corresponding height position is opened through the control panel 602. And based on the size of the molten material pile in the melting furnace, the regulating valve I 103, regulating valve II 105, air pump 201, and regulating valve III are controlled through the control panel 602. 202 and booster pump 401, thereby realizing the control of oxygen concentration and oxygen pressure in main oxygen supply pipe 102 and branch pipe 104, the control of air pressure in air delivery pipe 203, and the control of mixed gas pressure and oxygen concentration in air intake pipe 504 and air collection chamber 502.

[0039] When the concentration of oxygen supplied needs to be adjusted during the smelting process, the oxygen concentration and gas pressure are monitored in real time by pressure sensor I 106, concentration sensor I 107, pressure sensor II 305, concentration sensor II 306, pressure sensor III 510, and concentration sensor III 511. The main oxygen supply pipe 102 controls regulating valve I 103, regulating valve II 105, air pump 201, regulating valve III 202, and booster pump 401 to ensure that the oxygen concentration and pressure in pressure sensor I 106, concentration sensor I 107, pressure sensor II 305, concentration sensor II 306, pressure sensor III 510, and concentration sensor III 511 reach the set values, thus completing the automatic adjustment of oxygen supply.
