Description

[0002] The copper smelting anode furnace is mainly used for heating and producing copper materials, and is provided with a pure-oxygen burner which burns copper raw materials after mixing with fuel and pure oxygen, so as to quickly melt the copper raw materials and reduce carbon emissions.

[0003] The pure-oxygen burner uses high-purity oxygen to replace part or all of air for combustion, can improve combustion efficiency, reduce fuel consumption, and can promote more sufficient combustion and release more heat due to the high oxygen concentration of pure oxygen.

[0004] In the use process, it is inconvenient to control the stability of the use of the pure-oxygen burner of the copper smelting anode furnace, and the pure-oxygen burner body is prone to unstable positioning, which causes the pure-oxygen burner body to tilt and affects the use safety.

The support protrusions move to one side to drive the transmission rack to move to one side. The transmission rack moves to one side to drive the transmission gear to rotate. The transmission gear rotates to drive the circular sleeve to rotate. Since the sliding block and the circular sleeve are connected through the sliding groove, the circular sleeve rotates to drive the threaded rod to rotate. Since the threaded rod is screw-connected in the support plate, the circular sleeve can drive the threaded rod to rotate at the same time. In this way, the pure-oxygen burner body can be quickly fixed. The structure is simple, the operation is convenient, the time is saved, and the manpower is saved. The vertical support plate is subjected to the elastic force of the torsion spring, so as to drive the torsion spring to reverse, thereby driving the vertical support plate to reverse. The vertical support plate reverses to drive the limiting clamping plate to reverse. At this time, the limiting clamping plate can be clamped into the side of the transmission rack. In this way, the transmission rack can be limited, and the circular sleeve can be further fixed to prevent the circular sleeve from loosening.

[0007] And prior art (Chinese patent with application number CN201820009628.1 and application date 2018-01-04) a copper smelting anode furnace pure oxygen burner, which is provided with a pure oxygen filtering device on the structure, which is nested with the casing cover, the device fine filter screen is embedded and installed in the inside of the sealing element, can filter out some larger impurities in the air, then filter through the screen membrane and the center pipe, absorb pure oxygen, then transmit to the equipment for use, the sealing film seals and protects the connecting port, prevents pure oxygen leakage;
