Description

Technical Field

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

[0002] At present, a high proportion of steel mills are taking the route of low iron consumption. Under the condition of low iron consumption, the temperature of the molten pool is low in the early stage of the smelting process, and there is a serious flocculent road mouth phenomenon. At present, the furnace mouth is cleaned by equipment such as purging guns, manual purging with oxygen tubes, and furnace dismantling cars. When using oxygen guns for purging, the airflow is reflected to the flue, which seriously damages the equipment body and affects its service life. Manual purging and cleaning with oxygen in a high temperature environment is labor-intensive and unsafe. The cleaning of the furnace dismantling machine takes up production process time and affects production efficiency.

[0020] 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.

[0022] 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: 1. First check whether the hydraulic rod 8, oxygen supply assembly, cooling assembly and power mechanism are stably connected to the control cabinet 3.

[0023] 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 started, the support panel 10 and the various components on the support panel 10 are lifted to the same position as the converter height (the hydraulic rod 8 can be multi-stage, which can reduce the overall height in the retracted state).

[0024] 3. Turn on the power mechanism through the control cabinet 3. After the power mechanism is started, it drives the moving component to move. After the moving component moves, it can push the sleeve component to move inside the moving cavity 32 of the moving box 19 until the front end of the sleeve component is inserted into the converter, and then turn off the power mechanism.

[0025] 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, the sleeve component can be continuously cooled down until the inside of the converter is cleaned and stopped.

[0026] 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.

[0027] As a preferred embodiment 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 pipe 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 pipe 14, and the other end of the oxygen pipe 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 pipe 14, and the solenoid valve 12 is located on a side close to the oxygen point valve box 11. The oxygen point valve box 11, the oxygen pipe 14 and the sleeve assembly are internally connected.

[0028] 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 spray the inner wall of the converter.

[0029] Special mention should be made here: 1. The purpose of the oxygen flame arrester 13 is to prevent internal tempering of the converter.

[0030] 2. The oxygen point valve box 11, the solenoid valve 12 and the oxygen flame arrester 13 are all prior art, so their internal structures are not described in detail.

[0031] 3. The oxygen tube 14 is merely a pipe that can be used to transport oxygen, and is suitable for a hose here.

[0032] 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.

[0033] 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 a prior art and will not be described in detail). After entering the cooling cycle inside the sleeve assembly, it returns to the cooling box 15 from another coolant pipe 16.

[0034] 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 a cooling cavity 34, one end of the inner tube 36 is fixedly connected to the inner wall of the cooling cavity 34, the other end of the inner tube 36 passes through the cooling cavity 34, and an oxygen cavity 37 is provided on one side of the inner tube 36 passing through the cooling cavity 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 cavity 37 are internally connected, and the cooling cavity 34, the two water connectors 27 and the two coolant tubes 16 are internally connected.

[0035] More specifically, after the oxygen supply assembly and the cooling assembly are started, oxygen will enter the oxygen connector 28 through the oxygen pipe 14, then enter the inner tube 36, and be discharged into the converter from the other end of the oxygen chamber 37 inside the inner tube 36.

[0036] 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.

[0037] 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 .

[0038] 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.

[0039] 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 formed on the surface of the nozzle 21 , and the oxygen cavity 37 is connected to the inside of the plurality of nozzles 22 .

[0040] More specifically, by providing the nozzle 21 and the nozzle 22, oxygen can be better sprayed onto the inner wall of the converter.

[0041] 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, and 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] More specifically, when the threaded rod 30 rotates, the threaded block 31 can be driven to move, and then the moving block 29 located in the moving cavity 32 can be driven to move, thereby driving the outer tube 26 connected to the moving cavity 32 to move. And because the moving block 29 and the moving cavity 32 restrict each other, when the threaded rod 30 rotates, the threaded block 31 itself will not rotate, but only move horizontally.

[0046] As a preferred solution of the present invention, support columns 9 are fixedly connected to the four corners of the upper surface of the base plate 1, sliding cavities 25 are opened on the upper surfaces of the four support columns 9, anti-slip blocks 24 are slidably connected to the inner walls of the four sliding cavities 25, and sliding rods 23 are fixedly connected to the upper surfaces of the four anti-slip blocks 24. 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.

[0047] More specifically, by providing the support column 9 and the slide bar 23, four support points can be added around the hydraulic rod 8 to prevent the support panel 10 from tilting due to uneven force or other reasons. By providing the anti-drop block 24, the slide bar 23 can be prevented from falling off from the slide cavity 25 of the support column 9 (of course, the lifting height of the hydraulic rod 8 can be limited in advance through PLC control, or the inside of the support column 9 can also be set as an ordinary multi-section telescopic rod, which is not limited to the specifics).

[0048] As a preferred solution of the present invention, steering motors 4 are fixedly connected to the four corners of the upper surface of the base plate 1, the output shafts of the four steering motors 4 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 motors 6, the output shafts of the four forward motors 6 pass through one side of the support frame 5, and are respectively fixedly connected to the moving wheels 7.

[0049] More specifically, by providing 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.

[0050] The specific method is as follows: the steering motor 4 controls the steering function of the entire cart, and the forward motor 6 can control the rotation of the moving wheel 7 to realize the movement of the cart.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
