Description

Technical Field

[0001] The utility model relates to the technical field of sweeping vehicles, in particular to a high-efficiency converter furnace mouth sweeping vehicle. Background Art

[0002] Currently, a high percentage of steel mills are pursuing low iron consumption strategies. During this low iron consumption scenario, the molten pool temperature is relatively low in the early stages of the smelting process, resulting in severe flocculent furnace openings. Currently, furnace openings are cleaned using equipment such as lances, manual oxygen purging, and furnace dismantling vehicles. Oxygen lances, when used to purge, reflect airflow into the flue, severely damaging the equipment and shortening its service life. Manual oxygen purging in high-temperature environments is labor-intensive and unsafe. Furnace dismantling vehicles also take up time during production processes, impacting efficiency.

[0003] There are three major problems with this process:

[0004] 1. When the oxygen lance is purged for cleaning, excess oxygen is reflected into the flue, burning the flue steel slag, shortening the service life of the flue, and posing a safety hazard of flue leakage.

[0005] 2. The cleaning of the furnace dismantling machine takes up process time, reduces work efficiency, and increases the maintenance cost of the equipment.

[0006] 3. When manually burning the furnace mouth with oxygen behind the furnace, the worker is close to the furnace mouth, which results in high labor intensity. The reflected slag may scald the worker. Summary of the Invention

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figures 1-9 The cam 32 is connected to the upper and lower ends of the cam 32 by the support frame 11, and the support frame 12 is connected to the upper and lower ends of the cam 32 by the support frame 12.

[0032] like Figures 1 to 9 As shown, the high-efficiency converter furnace mouth purge vehicle of the present invention can be used in the following steps:

[0033] 1. First check whether the hydraulic rod 8, oxygen supply assembly, cooling assembly and power mechanism are stably connected to the control cabinet 3.

[0034] 2. Then, according to the height of the converter, the hydraulic rod 8 is turned on through the control cabinet 3. After the hydraulic rod 8 is turned on, the support panel 10 and the various components located on the support panel 10 are lifted to a position with the same height as the converter (the hydraulic rod 8 can be multi-stage, which can reduce the overall height in the retracted state).

[0035] 3. Turn on the power mechanism through the control cabinet 3. After the power mechanism is started, it drives the moving assembly to move. After the moving assembly moves, it can push the sleeve assembly to move inside the moving cavity 32 of the moving box 19 until the front end of the sleeve assembly is inserted into the converter, and then turn off the power mechanism.

[0036] 4. Turn on the oxygen supply component and the cooling component through the control cabinet 3. After the oxygen supply component is started, it will continuously supply oxygen to the inside of the sleeve component. After the cooling component is started, it can continuously cool the sleeve component until the inside of the converter is cleaned and stopped.

[0037] It should be noted that the control cabinet 3 can be intelligently controlled by a PLC controller or remotely controlled by a remote controller, without any specific limitation.

[0038] As a preferred solution of the present invention, the oxygen supply assembly includes an oxygen point valve box 11, a solenoid valve 12, an oxygen flame arrester 13 and an oxygen tube 14. The outer wall of the oxygen point valve box 11 is fixedly connected to the upper surface of the support panel 10, one end of the oxygen point valve box 11 is fixedly connected to one end of the oxygen tube 14, and the other end of the oxygen tube 14 is connected to one end of the sleeve assembly. The solenoid valve 12 and the oxygen flame arrester 13 are both installed on the outside of the oxygen tube 14, and the solenoid valve 12 is located on the side close to the oxygen point valve box 11. The oxygen point valve box 11, the oxygen tube 14 and the sleeve assembly are internally connected.

[0039] More specifically, when oxygen needs to be provided to the inside of the sleeve assembly, it is only necessary to open the solenoid valve 12 through the control cabinet 3. After the solenoid valve 12 is started, the oxygen point valve box 11 can transport external oxygen to the inside of the sleeve assembly through the oxygen pipe 14, and then the inner wall of the converter can be sprayed.

[0040] Special mention should be made here:

[0041] 1. The purpose of the oxygen flame arrester 13 is to prevent backfire inside the converter.

[0042] 2. The oxygen point valve box 11, the electromagnetic valve 12 and the oxygen flame arrester 13 are all prior art, so their internal structures are not described in detail.

[0043] 3. The oxygen tube 14 is merely a pipe for transporting oxygen and is suitable for use as a hose.

[0044] As a preferred solution of the present invention, the cooling assembly includes a cooling box 15 and two coolant pipes 16. The outer wall of the cooling box 15 is fixedly connected to the upper surface of the support panel 10, one side of the cooling box 15 is fixedly connected to one end of the two coolant pipes 16, and the other ends of the two coolant pipes 16 are connected to one end of the sleeve assembly.

[0045] More specifically, when the inside of the sleeve assembly needs to be cooled, it is only necessary to turn on the refrigeration equipment located inside the cooling box 15 to cool the coolant inside the cooling box 15. The cooled coolant is then pumped into one of the coolant pipes 16 by a circulation pump inside the cooling box 15 (this is existing technology and will not be described in detail). After entering the cooling cycle inside the sleeve assembly, it returns to the cooling box 15 from the other coolant pipe 16.

[0046] As a preferred embodiment of the present invention, the sleeve assembly includes an outer tube 26, an inner tube 36, an oxygen connector 28 and two water connectors 27. The lower ends of the two water connectors 27 are fixedly connected to one end of the outer tube 26. The inner wall of the outer tube 26 is connected to the cooling chamber 34. One end of the inner tube 36 is fixedly connected to the inner wall of the cooling chamber 34. The other end of the inner tube 36 passes through the cooling chamber 34. An oxygen chamber 37 is provided on one side of the inner tube 36 passing through the cooling chamber 34. The lower end of the oxygen connector 28 passes through the outer tube 26 and is fixedly connected to one end of the inner tube 36. The upper end of the oxygen connector 28 is fixedly connected to one end of the oxygen tube 14 away from the oxygen point valve box 11. The oxygen tube 14, the oxygen connector 28 and the oxygen chamber 37 are internally connected. The cooling chamber 34, the two water connectors 27 and the two coolant tubes 16 are internally connected.

[0047] More specifically, after the oxygen supply assembly and the cooling assembly are started, oxygen enters the oxygen connector 28 through the oxygen pipe 14, then enters the inner tube 36, and is discharged into the converter from the other end of the oxygen chamber 37 inside the inner tube 36.

[0048] Similarly, the coolant will be pumped into the coolant pipe 16 under the action of the circulation pump, then enter the water connector 27, and enter the cooling chamber 34 from the water connector 27 to cool the inner tube 36, and then return to the cooling box 15 from another coolant pipe 16.

[0049] As a preferred solution of the present invention, a diverter plate 35 is fixedly connected to the inner wall of the cooling chamber 34 , and two water connectors 27 are respectively located on both sides of the diverter plate 35 .

[0050] More specifically, by providing the diverter plate 35 , the two water connectors 27 can be separated, thereby forcing the coolant to circulate once outside the inner tube 36 and then return.

[0051] As a preferred solution of the present invention, one end of the inner tube 36 passing through the cooling cavity 34 is fixedly connected to the nozzle 21 , a plurality of nozzles 22 are opened on the surface of the nozzle 21 , and the oxygen cavity 37 is connected to the interior of the plurality of nozzles 22 .

[0052] More specifically, by providing the nozzle 21 and the nozzle 22 , oxygen can be better sprayed onto the inner wall of the converter.

[0053] As a preferred solution of the present invention, the power mechanism includes a moving motor 18 and a threaded rod 30. The outer wall of the moving motor 18 is fixedly connected to the side wall of one of the support blocks 17. The output shaft of the moving motor 18 is fixedly connected to one end of the threaded rod 30. The other end of the threaded rod 30 passes through the moving assembly and the two support blocks 17, and is rotatably connected to the inner walls of the two support blocks 17.

[0054] More specifically, because different converters may require different insertion depths of the sleeve assembly, the movement of the sleeve assembly can be controlled by a power mechanism, thereby being adaptable to more converters of different depths.

[0055] The specific method is: first, turn on the switch of the mobile motor 18 through the control cabinet 3. After the mobile motor 18 is started, the output shaft can drive the threaded rod 30 to rotate. After the threaded rod 30 rotates, it can drive the mobile component connected to the surface to move, and then the sleeve component can be driven to move through the mobile component.

[0056] As a preferred solution of the present invention, the moving assembly includes a moving block 29 and a threaded block 31. The threaded block 31 is sleeved and threadedly connected to the outer wall of the threaded rod 30. The upper surface of the threaded block 31 passes through the moving port 20 located at the lower end of the moving cavity 32 and is fixedly connected to the bottom surface of the moving block 29. The outer wall of the moving block 29 is slidably connected to the inner wall of the moving cavity 32, and one side of the moving block 29 is fixedly connected to one end of the outer tube 26.

[0057] More specifically, when the threaded rod 30 rotates, the threaded block 31 is driven to move, which in turn drives the moving block 29 located in the moving cavity 32 to move, thereby driving the outer tube 26 to move. Because the moving block 29 and the moving cavity 32 are mutually constrained, when the threaded rod 30 rotates, the threaded block 31 itself does not rotate, but only moves laterally.

[0058] As a preferred solution of the present invention, the four corners of the upper surface of the base plate 1 are fixedly connected with support columns 9, the upper surfaces of the four support columns 9 are provided with sliding cavities 25, the inner walls of the four sliding cavities 25 are slidably connected with anti-slip blocks 24, the upper surfaces of the four anti-slip blocks 24 are fixedly connected with sliding rods 23, the upper ends of the four sliding rods 23 respectively pass through the four sliding cavities 25, and are fixedly connected to the four corners of the bottom surface of the support panel 10.

[0059] More specifically, the provision of support columns 9 and slide bars 23 adds four support points around the hydraulic rod 8, preventing tilting of the support panel 10 due to uneven force or other factors. Furthermore, the provision of anti-dropout blocks 24 prevents the slide bar 23 from falling out of the slide cavity 25 of the support column 9. (Of course, it is also possible to pre-emptively limit the height of the hydraulic rod 8 through PLC control, or to configure the interior of the support column 9 as a conventional multi-section telescopic rod, without further limitation.)

[0060] As a preferred solution of the present invention, the four corners of the upper surface of the base plate 1 are fixedly connected to the steering motor 4, the output shafts of the four steering motors 4 all pass through the base plate 1, and are respectively fixedly connected to the support frame 5, the inner side of the four support frames 5 are fixedly connected to the forward motor 6, the output shafts of the four forward motors 6 all pass through one side of the support frame 5, and are respectively fixedly connected to the moving wheel 7.

[0061] More specifically, by setting up the steering motor 4 and the forward motor 6, when it is necessary to control the movement and steering of the entire cart, unified control can be performed through the control cabinet 3, which is more intelligent and reduces labor.

[0062] The specific method is as follows: the steering motor 4 controls the steering function of the entire cart, and the forward motor 6 can realize the movement of the cart by controlling the rotation of the moving wheels 7.

[0063] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
