Description

Technical Field

[0001] This invention relates to the field of reverberatory furnace flue design and modification technology, specifically to a reverberatory furnace tail flue. Background Technology

[0002] The reverberatory furnace process utilizes a self-developed technology to produce copper matte, processing 21,000 tons of copper slag annually, producing 7,000 tons of copper matte and 10,000 tons of crude lead. The reverberatory furnace uses a pure oxygen burner for heat, operating for 8 hours per furnace, with a natural gas consumption of 150 cubic meters per furnace. 3 With an air-fuel ratio of 2.5:1, the production process generates a large volume of flue gas containing a significant amount of sulfur-containing dust. This flue gas is highly corrosive and can easily carry materials from inside the furnace to the tail gas outlet, where it gradually accumulates and causes blockages. Regular shutdowns are required to clean the tail gas outlet, which necessitates using a gas blasting agent at high temperatures. This process is physically demanding for workers. Therefore, a tail gas outlet design for a reverberatory furnace is needed to address these issues. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a reverberatory furnace tail flue to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A reverberatory furnace tail flue includes:

[0007] The anti-clogging component is slidably connected inside the intake and exhaust ducts to perform preliminary cleaning of dust on the inner walls of the intake and exhaust ducts.

[0008] The steering component is rotatably connected to the middle of the intake flue and exhaust flue, and is connected to the anti-clogging component to drive the anti-clogging component to turn within the intake flue and exhaust flue.

[0009] The winding assembly is rotatably connected within the steering assembly, and its end is connected to the anti-clogging assembly, which is used to drive the anti-clogging assembly to slide within the intake flue and exhaust flue.

[0010] The cleaning component is rotatably connected inside the anti-clogging component, and its ends are slidably connected to the inner walls of the air intake duct and the exhaust duct, respectively.

[0011] The rotating component is slidably connected to the cleaning component and is used to cooperate with the cleaning component to achieve re-cleaning of the inner walls of the intake and exhaust flues.

[0012] As a preferred embodiment of the present invention, the anti-clogging component includes: a cleaning cylinder slidably connected inside the air intake duct and the exhaust duct; an elastic ring installed on the surface of the cleaning cylinder, the surface of the cleaning cylinder having at least two sets of through holes for communicating with the cleaning cylinder and the elastic ring; an air inlet nozzle installed at the end of the cleaning cylinder; and an exhaust port opened at the end of the cleaning cylinder, the axis of the exhaust port being inclined towards the inner wall of the air intake duct and the exhaust duct.

[0013] As a preferred embodiment of the present invention, the steering assembly includes: a device housing installed at the connection between the intake flue and the exhaust flue; an arc-shaped groove formed on the inner wall of the device housing; a first sliding groove formed on the inner wall of the device housing and communicating with one end of the arc-shaped groove; a second sliding groove formed on the inner wall of the device housing and communicating with the other end of the arc-shaped groove; a rotating shaft rotatably connected inside the device housing, with a steering component installed at its end; a telescopic cylinder fixed to the steering component, with a sliding column fixed to the side of the telescopic cylinder, and the end of the sliding column slidably connected to the inner walls of the arc-shaped groove, the first sliding groove, and the second sliding groove; and an adjusting rod rotatably connected inside the device housing, with a rotating carriage installed on its surface, and the surface of the sliding column slidably connected to the inside of the rotating carriage.

[0014] As a preferred embodiment of the present invention, the winding assembly includes: a winding rod rotatably connected inside the telescopic drum; a wire rope, one end of which is wound around the surface of the winding rod and the other end of which is connected to the inner wall of the cleaning drum; and a drive unit installed on the side of the telescopic drum, with the end of the winding rod connected to the output end of the drive unit.

[0015] As a preferred embodiment of the present invention, the cleaning assembly includes: a rotating rod rotatably connected inside the cleaning cylinder; a fan installed at the end of the rotating rod near the cleaning cylinder; and a cleaning frame rotatably connected to the end surface of the rotating rod away from the cleaning cylinder.

[0016] As a preferred embodiment of the present invention, the rotating assembly includes: a sliding member slidably connected to the surface of the rotating rod, the side of the sliding member being hinged to one end of the cleaning frame via a connecting rod; and a fixed frame fixed to the surface of the rotating rod, the fixed frame being connected to the surface of the sliding member via an elastic member.

[0017] As a preferred embodiment of the present invention, water tanks are respectively installed at the ends of the air intake flue and the exhaust flue.

[0018] As a preferred embodiment of the present invention, a protective cover is installed on the surface of the device box.

[0019] Compared with the prior art, the embodiments of this invention have the following beneficial effects: This invention connects the anti-clogging component to an external gas pipe. Driven by a portion of the high-pressure gas, the anti-clogging component expands until it tightly adheres to the inner wall of the inlet or outlet flue. The remaining gas acts on the inner wall of the inlet or outlet flue through the vents of the anti-clogging component. A winding component pulls the anti-clogging component to slide within the tail flue of the reverberatory furnace, allowing it to scrape away dust from the inner wall of the tail flue. A steering component allows the anti-clogging component to be freely switched between the inlet and outlet flues, facilitating separate cleaning of each. The high-pressure gas from the anti-clogging component drives the cleaning component to rotate, and the cleaning component opens under the action of the rotating component until it contacts the inner wall of the tail flue, allowing it to scrape away dust adhering to the inner wall again, thus improving the cleaning effect of the tail flue.

[0020] Compared to existing technologies, when cleaning the inner wall of the tail flue of the reverberatory furnace, the anti-clogging component and the winding component work together. The anti-clogging component expands under the action of some high-pressure gas, thereby scraping off the dust adhering to the inner wall of the tail flue of the reverberatory furnace. The anti-clogging component can also discharge the remaining high-pressure gas, thus achieving the cleaning of the inner wall of the tail flue of the reverberatory furnace.

[0021] Through the cooperation of the cleaning component and the rotating component, the cleaning component rotates under the drive of high-pressure gas from the anti-clogging component. As the rotation speed of the cleaning component increases, it opens up under the action of the rotating component, allowing it to scrape off the dust adhering to the inner wall of the reverberatory furnace tail flue again. This achieves the cleaning of the inner wall of the reverberatory furnace tail flue. By setting a steering component, the anti-clogging component can be turned, enabling the cleaning of the inner wall of the reverberatory furnace tail flue with corners. The reverberatory furnace tail flue has the advantages of being less prone to clogging and easy to clean.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0032] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0033] See Figures 1 to 7 A reverberatory furnace tail flue, comprising:

[0034] An air intake flue 1 is provided, and an exhaust flue 11 is connected to one end of the air intake flue 1.

[0035] The anti-clogging component 2 is slidably connected inside the intake flue 1 and the exhaust flue 11, and is used to perform preliminary cleaning of the dust on the inner wall of the intake flue 1 and the exhaust flue 11.

[0036] Steering component 3 is rotatably connected to the middle of intake flue 1 and exhaust flue 11, and connected to anti-clogging component 2, used to drive anti-clogging component 2 to turn within intake flue 1 and exhaust flue 11;

[0037] The winding assembly 4 is rotatably connected to the steering assembly 3, and its end is connected to the anti-clogging assembly 2, which is used to drive the anti-clogging assembly 2 to slide in the intake flue 1 and the exhaust flue 11.

[0038] Cleaning component 5 is rotatably connected inside anti-clogging component 2, and its ends are slidably connected to the inner walls of intake flue 1 and exhaust flue 11, respectively.

[0039] The rotating component 6 is slidably connected to the cleaning component 5 and is used to cooperate with the cleaning component 5 to achieve the re-cleaning of the inner walls of the intake flue 1 and the exhaust flue 11.

[0040] In an embodiment of the present invention, when it is necessary to clean a small amount of slag on the inner wall of the reverberatory furnace tail flue, the anti-clogging component 2 is connected to the external gas pipe. The anti-clogging component 2 expands under the drive of some high-pressure gas until it tightly adheres to the inner wall of the inlet flue 1 or the exhaust flue 11. The remaining gas acts on the inner wall of the inlet flue 1 or the exhaust flue 11 through the vents of the anti-clogging component 2. The winding component 4 pulls the anti-clogging component 2 to slide within the reverberatory furnace tail flue, allowing the anti-clogging component 2 to scrape away the dust on the inner wall of the reverberatory furnace tail flue. The steering component 3 allows the anti-clogging component 2 to be freely switched between the inlet flue 1 and the exhaust flue 11, facilitating the separate cleaning of the inlet flue 1 and the exhaust flue 11. The high-pressure gas from the anti-clogging component 2 drives the cleaning component 5 to rotate, and the cleaning component 5 opens under the action of the rotating component 6 until it contacts the inner wall of the reverberatory furnace tail flue. This allows the cleaning component 5 to scrape off the dust adhering to the inner wall of the reverberatory furnace tail flue again, improving the cleaning effect of the inner wall of the reverberatory furnace tail flue.

[0041] In one embodiment of the present invention, such as Figure 3 , Figure 5 and Figure 7 As shown, the anti-clogging component 2 includes:

[0042] The cleaning cylinder 21 is slidably connected inside the air intake flue 1 and the exhaust flue 11;

[0043] An elastic ring 22 is installed on the surface of a cleaning cylinder 21. At least two sets of through holes 25 are provided on the surface of the cleaning cylinder 21. The through holes 25 are used to connect the cleaning cylinder 21 and the elastic ring 22.

[0044] Air inlet 23 is installed at the end of cleaning cylinder 21;

[0045] An exhaust port 24 is provided at the end of the cleaning cylinder 21, and the axis of the exhaust port 24 is inclined to the inner wall of the intake flue 1 and the exhaust flue 11.

[0046] In this embodiment, the horizontal flue of the reverberatory furnace is changed to a vertical one, and the flue gas flow direction is also changed accordingly. The flue gas no longer flows horizontally to the furnace tail flue, but instead flows from the top of the furnace tail sequentially through the inlet flue 1 and the exhaust flue 11 to the furnace tail flue. The material carried by the flue gas will return to the reverberatory furnace for smelting and will not form blockages. The gas outlet of the reverberatory furnace no longer forms blockages, and only a small amount of slag needs to be cleaned from the gas outlet with a steel rod each shift, which greatly reduces the labor intensity of employees.

[0047] When it is necessary to clean a small amount of slag on the inner wall of the flue gas duct at the tail of the reverberatory furnace, first shut down the reverberatory furnace and connect the air inlet 23 to the external gas pipe. This allows external gas to enter the cleaning cylinder 21 through the air inlet 23, and the gas in the cleaning cylinder 21 can flow into the interior of the elastic ring 22 through the through hole 25, causing the elastic ring 22 to 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. At this time, the high-pressure gas in the cleaning cylinder 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] When the winding assembly 4 is activated, the winding assembly 4 can drive the elastic ring 22 to slide on the inner wall of the inlet flue 1 or the exhaust flue 11 through the cleaning cylinder 21. This allows the elastic ring 22 to cooperate with the high-pressure gas entering the inner wall of the inlet flue 1 or the exhaust flue 11 to scrape off the dust and debris on the inner wall of the inlet flue 1 or the exhaust flue 11, thereby cleaning the tail flue of the reverberatory furnace.

[0049] The exhaust holes 24 in the anti-clogging component 2 are distributed in a ring at intervals at the end of the cleaning cylinder 21, which facilitates the comprehensive cleaning of dust on the inner walls of the intake flue 1 and the exhaust flue 11.

[0050] In one embodiment of the present invention, such as Figure 3 and Figure 5 As shown, the steering component 3 includes:

[0051] Device box 31 is installed at the connection between intake flue 1 and exhaust flue 11;

[0052] An arc-shaped groove 32 is formed on the inner wall of the device box 31;

[0053] The first chute 321 is formed on the inner wall of the device box 31 and is connected to one end of the arc-shaped groove 32;

[0054] The second chute 322 is formed on the inner wall of the device box 31 and is connected to the other end of the arc-shaped groove 32;

[0055] A rotating shaft 33 is rotatably connected inside the device housing 31, and a steering component 34 is installed at its end;

[0056] Telescopic cylinder 35 is fixed on steering component 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 arc groove 32, first sliding groove 321, and second sliding groove 322.

[0057] The adjusting rod 37 is rotatably connected inside the device box 31, and a rotating slide 38 is mounted on its surface. The sliding column 36 is slidably connected to the inside of the rotating slide 38.

[0058] When it is necessary to switch the cleaning cylinder 21 from inside the intake flue 1 to inside the exhaust flue 11, the adjusting rod 37 is rotated counterclockwise. The adjusting rod 37 can drive the rotating slide 38 to rotate. Since the rotating slide 38 and the sliding column 36 are slidably connected, 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 then slide through the arc groove 32 to the inside of the first slide groove 321. After the sliding column 36 slides into the inside of the first slide groove 321, the sliding column 36 can drive the steering component 34 to rotate through the telescopic cylinder 35, so that the steering component 34 drives the rotating shaft 33 to rotate counterclockwise in the device box 31. Therefore, the end of the telescopic cylinder 35 will drive the cleaning cylinder 21 to rotate into the inside of the exhaust flue 11, thereby facilitating the cleaning cylinder 21 and the elastic ring 22 to clean the inner wall of the exhaust flue 11.

[0059] The cleaning cylinder 21 can be freely switched between the intake flue 1 and the exhaust flue 11 by means of the steering component 3, so as to facilitate cleaning of the intake flue 1 and the exhaust flue 11 respectively. The end of the adjusting rod 37 can also be connected to the output end of the motor that drives it to rotate, so as to drive the adjusting rod 37 to rotate stably in the device box 31.

[0060] In one embodiment of the present invention, such as Figure 5 As shown, the winding assembly 4 includes:

[0061] The winding rod 41 is rotatably connected inside the telescopic drum 35;

[0062] One end of the wire rope 42 is wrapped around the surface of the winding rod 41, and the other end is connected to the inner wall of the cleaning cylinder 21;

[0063] The drive unit 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 drive unit 43.

[0064] In this embodiment, when the drive unit 43 is activated, its output end can drive the winding rod 41 to rotate within the telescopic cylinder 35. This allows the winding rod 41 to wind or unwind the wire rope 42, enabling the wire rope 42 to pull the cleaning cylinder 21 to slide within the intake flue 1 or exhaust flue 11. When the winding rod 41 winds the wire rope 42, the wire rope 42 pulls the cleaning cylinder 21 upwards within the intake flue 1 or exhaust flue 11, at which point the telescopic cylinder 35 retracts. When the winding rod 41 unwinds the wire rope 42, the wire rope 42 pulls the cleaning cylinder 21 downwards within the intake flue 1 or exhaust flue 11, at which point the telescopic cylinder 35 extends. Thus, the cleaning cylinder 21 can drive the elastic ring 22 to slide in the 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 tail flue of the reverberatory furnace.

[0065] The drive component 43 can be a drive motor or a drive handle, which can be used to drive the winding rod 41 to rotate inside the telescopic drum 35. When the winding rod 41 unwinds the wire rope 42, the external high-pressure gas can be shut off to stop the expansion of the elastic ring 22, so that the elastic ring 22 can slide in the inlet flue 1 or the exhaust flue 11. A counterweight can be installed at the end of the cleaning drum 21 to accelerate the sliding of the cleaning drum 21 in the tail flue of the reverberatory furnace.

[0066] In one embodiment of the present invention, such as Figure 7 As shown, the cleaning component 5 includes:

[0067] The rotating rod 51 is rotatably connected inside the cleaning cylinder 21;

[0068] The blower 52 is installed at the end of the rotating rod 51 near the cleaning cylinder 21;

[0069] The cleaning frame 53 is rotatably connected to the end surface of the rotating rod 51 away from the cleaning cylinder 21.

[0070] In this embodiment, when the high-pressure gas in the cleaning cylinder 21 is discharged through the exhaust port 24, the blower 52 can drive the rotating rod 51 to rotate inside the cleaning cylinder 21 under the push of the gas. Thus, 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 inlet flue 1 or the exhaust flue 11, effectively improving the cleaning effect of the tail flue of the reverberatory furnace.

[0071] The end of the cleaning rack 53 can also be equipped with a scraper, which can be used to scrape off the dust adhering to the inner wall of the flue at the tail of the reverberatory furnace.

[0072] In one embodiment of the present invention, such as Figure 7As shown, the rotating component 6 includes:

[0073] The sliding member 61 is slidably connected to the surface of the rotating rod 51, and the side of the sliding member 61 is hinged to one end of the cleaning frame 53 via the connecting rod 62;

[0074] A fixing frame 63 is fixed to the surface of the rotating rod 51, and the fixing frame 63 is connected to the surface of the elastic member 64 and the sliding member 61.

[0075] In this embodiment, when the rotating rod 51 drives the cleaning frame 53 to rotate within the intake flue 1 or exhaust flue 11, as the rotational speed of the rotating rod 51 gradually increases, the centrifugal force on the cleaning frame 53 also gradually increases, causing the two sets of cleaning frames 53 to open up to each other. This allows the two sets of cleaning frames 53 to slide on the surface of the rotating rod 51 via the connecting rod 62, thereby compressing the elastic element 64. The elastic element 64 can be a compression spring, until the ends of both sets of cleaning frames 53 contact the interior of the intake flue 1 or exhaust flue 11. Therefore, the cleaning frame 53 can scrape off the dust on the inner wall of the tail flue of the reverberatory furnace during rotation.

[0076] With the cooperation of the winding assembly 4, the cleaning rack 53 can slide inside the inlet flue 1 or the exhaust flue 11, thereby thoroughly scraping off the dust adhering to the tail flue of the reverberatory furnace and improving the cleaning effect of the inner wall of the tail flue of the reverberatory furnace.

[0077] In one embodiment of the present invention, such as Figure 1 As shown, water tanks 10 are installed at the ends of the air intake flue 1 and the exhaust flue 11, respectively. By circulating cooling water into the water tanks 10, the water tanks 10 can cool down the tail flue of the reverberatory furnace, making it easier to clean the inner wall of the tail flue.

[0078] In one embodiment of the present invention, such as Figure 1 As shown, a protective cover 311 is installed on the surface of the device box 31. The protective cover 311 and the device box 31 can be connected by bolts, allowing the protective cover 311 to be disassembled and the components inside the device box 31 to be inspected. Furthermore, the cleaning cylinder 21 and the telescopic cylinder 35 can be connected by threads, allowing the cleaning cylinder 21 to be removed from the device box 31, thereby reducing the resistance of the exhaust gas from the reverberatory furnace through the device box 31 and improving the exhaust gas emission efficiency.

[0079] The working principle of this invention is as follows: When it is necessary to clean a small amount of slag on the inner wall of the flue gas duct at the tail of the reverberatory furnace, the reverberatory furnace is closed, and the air inlet 23 is connected to the external gas pipe. Thus, the external gas can enter the cleaning cylinder 21 through the air inlet 23, and the gas in the cleaning cylinder 21 can flow into the interior 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. Thus, the high-pressure gas in the cleaning cylinder 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.

[0080] The winding assembly 4 is activated. The winding assembly 4, through the cleaning cylinder 21, drives the elastic ring 22 to slide against the inner wall of the inlet flue 1 or the exhaust flue 11. This allows the elastic ring 22 to cooperate with the high-pressure gas entering the inner wall of the inlet flue 1 or the exhaust flue 11, scraping away dust and debris, thus cleaning the tail flue of the reverberatory furnace. The steering assembly 3 allows the cleaning cylinder 21 to be freely switched between the inlet flue 1 and the exhaust flue 11, enabling separate cleaning of each flue.

[0081] When the high-pressure gas in the cleaning cylinder 21 is discharged through the exhaust port 24, the fan 52 can drive the rotating rod 51 to rotate inside the cleaning cylinder 21 under the push of the gas. Thus, the rotating rod 51 can drive the cleaning frame 53 at its end to rotate synchronously. As the rotation speed of the rotating rod 51 gradually increases, the centrifugal force on the cleaning frame 53 will also gradually increase. The two sets of cleaning frames 53 will open up to each other, so that the two sets of cleaning frames 53 can drive the sliding part 61 to slide on the surface of the rotating rod 51 through the connecting rod 62 until the ends of the two sets of cleaning frames 53 contact the inside of the inlet flue 1 or the exhaust flue 11. Therefore, the cleaning frame 53 can scrape off the dust on the inner wall of the tail flue of the reverberatory furnace during the rotation process.
