DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] See also Figure 1 to Figure 7 , a reverberatory furnace tail flue, comprising: An air inlet flue 1, wherein the end of the air inlet flue 1 is connected to an exhaust flue 11; The anti-blocking component 2 is slidably connected in the air intake flue 1 and the exhaust flue 11, and is used for preliminary cleaning of dust on the inner walls of the air intake flue 1 and the exhaust flue 11; The steering assembly 3 is rotatably connected to the middle of the air inlet flue 1 and the exhaust flue 11, and is connected to the anti-blocking assembly 2, and is used to drive the anti-blocking assembly 2 to turn in the air inlet flue 1 and the exhaust flue 11; The winding assembly 4 is rotatably connected in the steering assembly 3, and the end portion is connected to the anti-blocking assembly 2, and is used to drive the anti-blocking assembly 2 to slide in the air inlet flue 1 and the exhaust flue 11; The cleaning component 5 is rotatably connected in the anti-blocking component 2, and the ends thereof are respectively slidably connected to the inner walls of the air inlet flue 1 and the exhaust flue 11; The rotating assembly 6 is slidably connected to the cleaning assembly 5 and is used to cooperate with the cleaning assembly 5 to achieve re-cleaning of the inner walls of the air intake flue 1 and the exhaust flue 11.

[0027] In an embodiment of the present invention, when it is necessary to clean a small amount of slag on the inner wall of the flue at the tail of the reverberatory furnace, the anti-blocking component 2 is connected to the external air pipe, and the anti-blocking component 2 will expand under the drive of part of the high-pressure gas until the anti-blocking component 2 is tightly attached to the inner wall of the air intake flue 1 or the exhaust flue 11, and the remaining gas will act on the inner wall of the air intake flue 1 or the exhaust flue 11 through the air holes of the anti-blocking component 2, and the anti-blocking component 2 is pulled to slide in the flue at the tail of the reverberatory furnace by the winding component 4, so that the anti-blocking component 2 can scrape the dust on the inner wall of the flue at the tail of the reverberatory furnace. The anti-blocking component 2 can be freely switched in the air intake flue 1 and the exhaust flue 11 by the steering component 3, so as to facilitate the cleaning of the air intake flue 1 and the exhaust flue 11 respectively. The high-pressure gas passing through the anti-clogging component 2 will drive the cleaning component 5 to rotate, and the cleaning component 5 will open under the action of the rotating component 6 until the cleaning component 5 contacts the inner wall of the flue at the tail end of the reverberatory furnace, so that the cleaning component 5 can scrape off the dust adhered to the inner wall of the flue at the tail end of the reverberatory furnace again, thereby improving the cleaning effect of the inner wall of the flue at the tail end of the reverberatory furnace.

[0028] In one embodiment of the present invention, Figure 3 , Figure 5 and Figure 7 As shown, the anti-blocking component 2 includes: The cleaning cylinder 21 is slidably connected inside the air inlet flue 1 and the exhaust flue 11; The elastic ring 22 is installed on the surface of the cleaning cylinder 21. The surface of the cleaning cylinder 21 is provided with at least two groups of through holes 25. The through holes 25 are used to connect the cleaning cylinder 21 and the elastic ring 22. An air inlet nozzle 23 is installed at the end of the cleaning cylinder 21; The exhaust hole 24 is provided at the end of the cleaning tube 21 , and the axis of the exhaust hole 24 is tilted toward the inner wall of the air inlet flue 1 and the exhaust flue 11 .

[0029] In this embodiment, the flue at the tail of the reverberatory furnace is changed from horizontal to vertical, and the direction of the flue gas is also changed accordingly. The flue gas flows from the original horizontal flow to the tail flue at the tail of the furnace to the flow from the top of the tail of the furnace through the air intake flue 1 and the exhaust flue 11 in sequence to the tail flue at the tail of the furnace. The materials carried by the flue gas will return to the reverberatory furnace for smelting, and will not form a blockage. The outlet of the reverberatory furnace will no longer form a blockage. Each shift only needs to use a steel chisel to clean a small amount of slag at the outlet, and the labor intensity of employees is greatly reduced.

[0030] When it is necessary to clean a small amount of slag on the inner wall of the flue at the tail of the reverberatory furnace, first close the reverberatory furnace, connect the air inlet nozzle 23 with the external air pipe, so that the external gas can enter the cleaning tube 21 through the air inlet nozzle 23, and the gas in the cleaning tube 21 can flow into the inside of the elastic ring 22 through the through hole 25, so that the elastic ring 22 can expand. When the surface of the expanded elastic ring 22 contacts the inner wall of the air inlet flue 1 or the exhaust flue 11, the elastic ring 22 will stop expanding, so that the high-pressure gas in the cleaning tube 21 can be discharged through the exhaust hole 24, so that the discharged high-pressure gas can clean the dust inside the air inlet flue 1 and the exhaust flue 11.

[0031] Open the winding assembly 4, and the winding assembly 4 can drive the elastic ring 22 to slide on the inner wall of the air inlet flue 1 or the exhaust flue 11 through the cleaning tube 21, so that the elastic ring 22 can cooperate with the high-pressure gas entering the inner wall of the air inlet flue 1 and the exhaust flue 11 to scrape off the dust and debris on the inner wall of the air inlet flue 1 and the exhaust flue 11, thereby cleaning the flue at the tail of the reverberatory furnace.

[0032] The exhaust holes 24 in the anti-clogging component 2 are distributed in an annular manner at intervals at the end of the cleaning tube 21, so as to facilitate comprehensive cleaning of dust on the inner walls of the air inlet flue 1 and the exhaust flue 11.

[0033] In one embodiment of the present invention, Figure 3 and Figure 5 As shown, the steering assembly 3 includes: The device box 31 is installed at the connection between the air inlet flue 1 and the exhaust flue 11; An arc-shaped groove 32 is provided on the inner wall of the device box 31; The first slide groove 321 is provided on the inner wall of the device box 31 and communicates with one end of the arc groove 32; The second slide groove 322 is formed on the inner wall of the device box 31 and communicates with the other end of the arc groove 32; A rotating shaft 33 is rotatably connected to the inside of the device box 31, and a steering member 34 is installed at the end thereof; The telescopic cylinder 35 is fixed on the steering member 34. A sliding column 36 is fixed on the side of the telescopic cylinder 35. The end of the sliding column 36 is slidably connected to the inner wall of the arc groove 32, the first sliding groove 321, and the second sliding groove 322. The adjusting rod 37 is rotatably connected in the device box 31 , and a rotating slide 38 is mounted on the surface thereof. The surface of the sliding column 36 is slidably connected inside the rotating slide 38 .

[0034] When it is necessary to switch the cleaning cylinder 21 from the inside of the air intake flue 1 to the inside of the exhaust flue 11, the adjusting rod 37 is rotated counterclockwise, and the adjusting rod 37 can drive the rotating slide 38 to rotate. Since the rotating slide 38 and the sliding column 36 are connected by sliding on the surface, the sliding column 36 can slide from the second slide groove 322 to the inside of the arc groove 32 under the push of the rotating slide 38, and slide through the arc groove 32 to the inside of the first slide groove 321. After the sliding column 36 slides to the inside of the first slide groove 321, the sliding column 36 can drive the steering member 34 to rotate through the telescopic cylinder 35, so that the steering member 34 drives the rotating shaft 33 to rotate counterclockwise in the device box 31, so that the end of the telescopic cylinder 35 will drive the cleaning cylinder 21 to rotate to the inside of the exhaust flue 11, so that the cleaning cylinder 21 and the elastic ring 22 can clean the inner wall of the exhaust flue 11.

[0035] The cleaning cylinder 21 can be freely switched between the air intake duct 1 and the exhaust duct 11 through the steering assembly 3, so as to clean the air intake duct 1 and the exhaust duct 11 respectively. The end of the adjusting rod 37 can also be connected to the output end of the motor driving it to rotate, so as to drive the adjusting rod 37 to rotate stably in the device box 31.

[0036] In one embodiment of the present invention, Figure 5 As shown, the winding assembly 4 includes: The reeling rod 41 is rotatably connected to the inside of the telescopic cylinder 35; A steel wire rope 42, one end of which is wound around the surface of the winding rod 41, and the other end of which is connected to the inner wall of the cleaning cylinder 21; The driving member 43 is installed on the side of the telescopic cylinder 35 , and the end of the winding rod 41 is connected to the output end of the driving member 43 .

[0037] In this embodiment, the driving member 43 is turned on, and the output end of the driving member 43 can drive the winding rod 41 to rotate in the telescopic cylinder 35, so that the winding rod 41 can wind up or unwind the wire rope 42, so that the wire rope 42 can pull the cleaning cylinder 21 to slide in the air intake flue 1 or the exhaust flue 11. When the winding rod 41 winds up the wire rope 42, the wire rope 42 can pull the cleaning cylinder 21 to rise in the air intake flue 1 or the exhaust flue 11, and the telescopic cylinder 35 contracts; when the winding rod 41 unwinds the wire rope 42, the wire rope 42 can pull the cleaning cylinder 21 to descend in the air intake flue 1 or the exhaust flue 11, and the telescopic cylinder 35 extends. Thus, the cleaning tube 21 can drive the elastic ring 22 to slide in the air inlet flue 1 or the exhaust flue 11, so that the elastic ring 22 can cooperate with the high-pressure gas discharged from the exhaust hole 24 to clean the dust on the inner wall of the flue at the tail of the reverberatory furnace.

[0038] The driving member 43 can be a driving motor or a driving handle, which can drive the winding rod 41 to rotate in the telescopic cylinder 35. When the winding rod 41 unwinds the wire rope 42, the external high-pressure gas can be closed, and the expansion of the elastic ring 22 can be stopped, so that the elastic ring 22 can slide in the air intake flue 1 or the exhaust flue 11, and a counterweight can be installed at the end of the cleaning cylinder 21, so as to speed up the sliding of the cleaning cylinder 21 in the flue at the tail of the reverberatory furnace.

[0039] In one embodiment of the present invention, Figure 7 As shown, the cleaning component 5 includes: A rotating rod 51 is rotatably connected to the interior of the cleaning cylinder 21; The fan 52 is mounted on the end of the rotating rod 51 close to the cleaning cylinder 21; The cleaning frame 53 is rotatably connected to the end surface of the rotating rod 51 away from the cleaning cylinder 21.

[0040] In this embodiment, when the high-pressure gas in the cleaning cylinder 21 is discharged through the exhaust hole 24, the fan 52 can drive the rotating rod 51 to rotate in the cleaning cylinder 21 under the impetus of the gas, so that the rotating rod 51 can drive the cleaning frame 53 at its end to rotate synchronously, so that the end of the cleaning frame 53 can scrape off the dust on the inner wall of the air inlet flue 1 or the exhaust flue 11, effectively improving the cleaning effect of the flue at the tail of the reverberatory furnace.

[0041] A scraper can also be installed at the end of the cleaning frame 53, and the dust adhering to the inner wall of the flue at the tail of the reverberatory furnace can be scraped off by the scraper.

[0042] In one embodiment of the present invention, Figure 7 As shown, the rotating assembly 6 includes: A sliding member 61 is slidably connected to the surface of the rotating rod 51, and the side surface of the sliding member 61 is hinged to one end of the cleaning frame 53 through a connecting rod 62; The fixing frame 63 is fixed on the surface of the rotating rod 51 , and the fixing frame 63 is connected to the surface of the sliding member 61 through the elastic member 64 .

[0043] In this embodiment, when the rotating rod 51 drives the cleaning frame 53 to rotate in the air inlet flue 1 or the exhaust flue 11, as the rotation speed of the rotating rod 51 gradually increases, the centrifugal force exerted on the cleaning frame 53 will also gradually increase, so that the two groups of cleaning frames 53 will open to each other, so that the two groups of cleaning frames 53 can drive the sliding member 61 to slide on the surface of the rotating rod 51 through the connecting rod 62, so that the sliding member 61 can compress the elastic member 64, and the elastic member 64 can adopt a compression spring, until the ends of the two groups of cleaning frames 53 are in contact with the inside of the air inlet flue 1 or the exhaust flue 11, so that the cleaning frame 53 can scrape the dust on the inner wall of the flue at the tail of the reverberatory furnace during the rotation process.

[0044] With the cooperation of the winding assembly 4, the cleaning rack 53 can slide in the air inlet flue 1 or the exhaust flue 11, so as to completely scrape off the dust adhered to the flue at the tail end of the reverberatory furnace, thereby improving the cleaning effect of the inner wall of the flue at the tail end of the reverberatory furnace.

[0045] In one embodiment of the present invention, Figure 1 As shown, water tanks 10 are respectively installed at the ends of the air inlet flue 1 and the exhaust flue 11. By introducing circulating cooling water into the water tank 10, the water tank 10 can cool down the flue at the tail of the reverberatory furnace, which is convenient for cleaning the inner wall of the flue at the tail of the reverberatory furnace.

[0046] In one embodiment of the present invention, Figure 1 As shown, a protective cover 310 is installed on the surface of the device box 31. The protective cover 310 and the device box 31 can be connected by bolts, so that the protective cover 310 can be disassembled, and then the components in the device box 31 can be repaired. In addition, the cleaning cylinder 21 and the telescopic cylinder 35 can be connected by threads, so that the cleaning cylinder 21 can be disassembled and taken out from the device box 31, thereby reducing the resistance of the exhaust gas at the tail of the reverberatory furnace passing through the device box 31 and improving the exhaust gas emission effect.

[0047] The working principle of the present invention is: when it is necessary to clean a small amount of slag on the inner wall of the flue at the tail of the reverberatory furnace, the reverberatory furnace is closed, and the air inlet nozzle 23 is connected to the external air pipe, so that the external gas can enter the cleaning tube 21 through the air inlet nozzle 23, and the gas in the cleaning tube 21 can flow into the inside of the elastic ring 22 through the through hole 25, so that the elastic ring 22 can expand. When the surface of the expanded elastic ring 22 contacts the inner wall of the air inlet flue 1 or the exhaust flue 11, the elastic ring 22 will stop expanding, so that the high-pressure gas in the cleaning tube 21 can be discharged through the exhaust hole 24, so that the discharged high-pressure gas can clean the dust inside the air inlet flue 1 and the exhaust flue 11.

[0048] The winding assembly 4 is opened, and the winding assembly 4 can drive the elastic ring 22 to slide on the inner wall of the air intake flue 1 or the exhaust flue 11 through the cleaning cylinder 21, so that the elastic ring 22 can cooperate with the high-pressure gas entering the inner wall of the air intake flue 1 and the exhaust flue 11 to scrape away the dust and debris on the inner wall of the air intake flue 1 and the exhaust flue 11, thereby cleaning the flue at the tail of the reverberatory furnace. The cleaning cylinder 21 can be freely switched in the air intake flue 1 and the exhaust flue 11 through the steering assembly 3, so that the air intake flue 1 and the exhaust flue 11 can be cleaned separately.

[0049] When the high-pressure gas in the cleaning cylinder 21 is discharged through the exhaust hole 24, the fan 52 can drive the rotating rod 51 to rotate in the cleaning cylinder 21 under the impetus of the gas, so that the rotating rod 51 can drive the cleaning frame 53 at its end to rotate synchronously. When the rotation speed of the rotating rod 51 gradually increases, the centrifugal force exerted on the cleaning frame 53 will gradually increase, and the two groups of cleaning frames 53 will open to each other, so that the two groups of cleaning frames 53 can drive the sliding member 61 to slide on the surface of the rotating rod 51 through the connecting rod 62 until the ends of the two groups of cleaning frames 53 are in contact with the inside of the air inlet flue 1 or the exhaust flue 11, so the cleaning frame 53 can scrape the dust on the inner wall of the flue at the tail of the reverberatory furnace during the rotation process.
