Specific embodiment
As shown in Figure 1, the automatic oxygen blowing device of smelting furnace, including oxygen lance 5, oxygen lance 5 is interior to be equipped with along its axial direction
Cooling water circulation channel, 5 top of oxygen lance are connected with oxygen feeding tube road 12 and cooling water circulating pipe, the cooling water circulation channel
Interior to be equipped with temperature sensor 57, as shown in figure 3, the oxygen lance 5 is obliquely installed, 5 side of oxygen lance is arranged in parallel with fixed
Guide rail 4 is set with sliding block 6 on guide rail 4, and the lateral surface of sliding block 6 is packed on oxygen lance 5, and the bottom of oxygen lance 5 is close to smelting furnace
1 oxygen blast mouth；The upper surface of sliding block 6 is connected with the driving device for sliding up and down sliding block 6 along guide rail 4, and driving device, temperature pass
Sensor 57, oxygen feeding tube road 12 switched into oxygen and the water inlet switch of cooling water circulating pipe is all connected with controller 13, controller 13
It is equipped with the alarm system matched with temperature sensor 57.Above-mentioned temperature sensor 57 can be reflected in real time by monitoring temperature
The case where cooling water recycles is higher than preset temperature, temperature sensor 57 when cooling water does not recycle or when water shortage, temperature can be higher
Signal is transmitted to controller 13, controller 13 issues alarm system and instructs, and alarm system issues sound-light alarm, reminds operation
Work is found, processing in time in time convenient for operative employee.
As Figure 2-3, the oxygen lance 5 is made of inner tube 51, intermediate tube 52, outer tube 53, the top edge of intermediate tube 52
Outer tube 53 stretches out, and the top of inner tube 51 is stretched out along intermediate tube 52, is into oxygen channel, between inner tube 51 and intermediate tube 52 in inner tube 51
It is exhalant canal between intermediate tube 52 and outer tube 53 for intake tunnel, intake tunnel is connected to the bottom of exhalant canal, is formed cold
But water circulation channel；The top of inner tube 51 is equipped with oxygen feeder 54, and oxygen feeder 54 connects oxygen feeding tube road 12, the tip side of intermediate tube 52
Face is equipped with water inlet 55, and water inlet 55 connects water inlet pipe 8, and 53 top side of outer tube is equipped with water outlet 56, and water outlet 56 connects out
Water pipe 7, water inlet pipe 8 and outlet pipe 7 form cooling water circulating pipe.
Preferably, the driving device includes the cylinder 11 placed vertically, and oil cylinder 10, cylinder 11 are connected with above cylinder 11
Upward with the piston rod of oil cylinder 10, the affixed wirerope 9 of the piston rod of oil cylinder 10, the other end of wirerope 9 is fixed in sliding block 6
Upper surface.Oil cylinder 10 is pushed up using cylinder 11 to control the movement of sliding block 6, this structure is relative to only with oil cylinder control sliding block 6
