Description

Technical Field

[0001] This invention relates to the field of sintering machine technology, and more specifically, to a flue gas flow conversion device for a dust collection pipe in a sintering machine. Background Technology

[0002] The sintering machine trolley is equipped with multiple continuous dust collection air boxes at its lower part. Each air box is connected to a dust settling pipe at its lower part, which ultimately connects to the sintering machine's main flue. Cold air passes through the sintering machine and combusts with the sintered ore to generate hot air. The hot air is collected by the dust collection air boxes and then enters the sintering main flue through the dust settling pipes below the air boxes.

[0003] However, when the flue gas enters the flue gas flow conversion device of the existing sintering machine dust pipe, it is easy to cause blockage due to impurities in the flue gas, making it difficult to discharge the flue gas, thus affecting its use to some extent. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a flue gas flow conversion device for the dust collection pipe of a sintering machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flue gas flow conversion device for a dust collection pipe of a sintering machine, comprising:

[0007] The processing tube has a smoke inlet pipe at one end and a smoke outlet pipe at the other end. A partition is fixedly connected inside the processing tube, and the inside of the processing tube is divided into a first channel and a second channel by the partition. A filter screen is fixedly connected inside both the first channel and the second channel. A baffle is movably connected inside the partition.

[0008] The cleaning plate is fixedly connected to the side wall of the baffle. The baffle moves inside the treatment tube, causing the cleaning plate to move and clean the filter screen.

[0009] Preferably, a pneumatic telescopic rod is fixedly connected to the outer wall of the processing tube, a connecting rod is fixedly connected to the moving end of the pneumatic telescopic rod, a moving rod is fixedly connected to the connecting rod, and the moving rod passes through the side wall of the processing tube and is fixedly connected to the stop block.

[0010] Preferably, a liquid container is fixedly connected to the top of the processing tube, a block is provided at the liquid inlet at the top of the liquid container, an inlet is opened on the side wall of the processing tube, the inlet communicates with the liquid container, a baffle is movably connected inside the inlet, and an outlet tube is fixedly connected inside the liquid container.

[0011] Preferably, an elastic element is fixedly connected to the inner wall of the liquid container, and the bottom of the elastic element is fixedly connected to the baffle.

[0012] Preferably, a movable block is fixedly connected to the lower surface of the baffle, a first triangular block is fixedly connected to the movable block, and a second triangular block is fixedly connected to the baffle.

[0013] Preferably, the bottom of the processing tube is connected to a liquid carrier box, and a liquid-blocking block is provided at the drain port of the liquid carrier box.

[0014] Preferably, the smoke inlet pipe is connected to a flexible hose, a control valve is installed on the flexible hose, an air inlet channel is opened on the movable rod, the air inlet channel is connected to the flexible hose, a cavity is opened on the stop block, a connecting plate is fixedly connected to the stop block, an air outlet pipe is fixedly connected to the connecting plate, the air inlet channel is connected to the cavity, and the cavity is connected to the air outlet pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, a first channel and a second channel are formed inside the processing tube by a partition. A filter screen is fixedly connected inside both the first and second channels. Since the flue gas contains impurities, these impurities adhere to the filter screen when the flue gas enters the first or second channel. When cleaning of the filter screen in the first or second channel is required, a pneumatic telescopic rod moves the connecting rod. During this movement, a moving rod moves, and during this movement, a stop block moves. Since the size of the stop block is larger than that of the first channel and the second channel, when the stop block is directly in front of the first channel, the first channel is closed; when the stop block is directly in front of the second channel, the second channel is closed. This allows for the switching between the first and second channels.

[0017] 2. In this invention, by setting a cleaning plate and a liquid outlet pipe, it is convenient to clean the filter screen. The cleaning liquid discharged from the liquid outlet pipe flows onto the filter screen, which facilitates the cleaning of the filter screen. The pneumatic telescopic rod works to move the connecting rod. During the movement of the connecting rod, the moving rod moves. During the movement of the moving rod, the stop moves. During the movement of the stop, the cleaning plate moves. Since one end of the cleaning plate is attached to the side wall of the filter screen, the filter screen is cleaned during the movement of the cleaning plate. Attached Figure Description

[0032] Reference Figures 1 to 8 .

[0033] 5. Example 1 further illustrates the flue gas flow conversion device for the dust collection pipe of a sintering machine proposed in this invention.

[0034] illustrate.

[0035] A flue gas flow conversion device for a dust collection pipe of a sintering machine, comprising:

[0036] Treatment pipe 1, one end of which is connected to smoke inlet pipe 2, and the other end of which is connected to smoke outlet pipe 2.

[0037] A partition 4 is fixedly connected inside the tube 3 and the treatment tube 1. The interior of the treatment tube 1 is divided by the partition 4 into a first channel 5 and a second channel 6. Filters are fixedly connected inside both the first channel 5 and the second channel 6.

[0038] Net 7, partition 4 has a movable connection with a stop 8;

[0039] The cleaning plate 9 is fixedly connected to the side wall of the baffle 8. The baffle 8 moves inside the treatment tube 1, which drives the cleaning plate 9 to move. The moving cleaning plate 9 cleans the filter screen 7.

[0040] A pneumatic telescopic rod 10 is fixedly connected to the outer wall of the treatment pipe 1. A connecting rod 11 is fixedly connected to the moving end of the pneumatic telescopic rod 10. A moving rod 12 is fixedly connected to the connecting rod 11. The moving rod 12 passes through the side wall of the treatment pipe 1 and is fixedly connected to the baffle 8. Since the flue gas contains impurities, when the flue gas enters the interior of the first channel 5 or the second channel 6, the impurities in the flue gas adhere to the filter screen 7. When it is necessary to clean the filter screen 7 of the first channel 5 or the filter screen 7 of the second channel 6, the pneumatic telescopic rod 10 works to move the connecting rod 11. During the movement of the connecting rod 11, the moving rod 12 moves. During the movement of the moving rod 12, the stop block 8 moves. Since the size of the stop block 8 is larger than the size of the first channel 5 and the size of the second channel 6, when the stop block 8 is directly in front of the first channel 5, the first channel 5 is closed by the stop block 8. When the stop block 8 is directly in front of the second channel 6, the second channel 6 is closed by the stop block 8. During the movement of the stop block 8, the cleaning plate 9 is moved. Since one end of the cleaning plate 9 is attached to the side wall of the filter screen 7, the filter screen 7 is cleaned during the movement of the cleaning plate 9, that is, impurities are removed from the filter screen 7.

[0041] A liquid container 13 is fixedly connected to the top of the treatment tube 1. A block 14 is provided at the liquid inlet at the top of the liquid container 13. An inlet 15 is opened on the side wall of the treatment tube 1. The inlet 15 is connected to the liquid container 13. A baffle 16 is movably connected inside the inlet 15. An outlet tube 17 is fixedly connected inside the liquid container 13. When it is necessary to add cleaning fluid inside the liquid container 13, the operator pulls out the block 14 from the liquid inlet at the top of the liquid container 13 and adds cleaning fluid inside the liquid container 13 through the liquid inlet.

[0042] An elastic element 18 is fixedly connected to the inner wall of the liquid container 13. The bottom of the elastic element 18 is fixedly connected to the baffle 16. The elastic element 18 can be a spring.

[0043] A movable block 19 is fixedly connected to the lower surface of the baffle 16. A first triangular block 20 is fixedly connected to the movable block 19, and a second triangular block 21 is fixedly connected to the stop block 8. During the movement of the stop block 8, the second triangular block 21 moves. When the second triangular block 21 interacts with the first triangular block 20, the second triangular block 21 pushes the first triangular block 20 to move upward. During the upward movement of the first triangular block 20, the baffle 16 moves upward through the movable block 19. When the baffle 16 moves from the inlet 15 to the interior of the liquid filling box 13, the elastic element 18 at this time... In the compressed state, the cleaning fluid inside the liquid box 13 flows to the outlet pipe 17 through the inlet 15. Since the outlet pipe 17 is located above the filter screen 7, the cleaning fluid discharged from the outlet pipe 17 flows onto the filter screen 7, facilitating the cleaning of the filter screen 7. The pneumatic telescopic rod 10 operates to move the connecting rod 11. During the movement of the connecting rod 11, the moving rod 12 moves. During the movement of the moving rod 12, the stop block 8 moves. During the movement of the stop block 8, the cleaning plate 9 moves. Since one end of the cleaning plate 9 is attached to the side wall of the filter screen 7, the filter screen 7 is cleaned during the movement of the cleaning plate 9.

[0044] As the stop block 8 continues to move, the second triangular block 21 separates from the first triangular block 20. Due to the elastic reset effect of the elastic element 18, the baffle 16 moves into the inlet 15. The baffle 16 seals the inlet 15, preventing the cleaning fluid inside the liquid box 13 from being discharged through the inlet 15.

[0045] The bottom of the treatment tube 1 is connected to a liquid carrier box 22. A liquid baffle 23 is provided at the drain port of the liquid carrier box 22. The cleaning liquid after cleaning the filter screen 7 flows into the liquid carrier box 22 and is stored in the liquid carrier box 22. When it is necessary to drain the liquid stored in the liquid carrier box 22, the operator pulls the liquid baffle 23 out from the drain port of the liquid carrier box 22, so that the liquid inside the liquid carrier box 22 can be discharged through the drain port.

[0046] Working principle: Due to the impurities in the flue gas, when the flue gas enters the first channel 5 or the second channel 6, the impurities in the flue gas adhere to the filter screen 7. When it is necessary to clean the filter screen 7 of the first channel 5 or the filter screen 7 of the second channel 6, the pneumatic telescopic rod 10 works to move the connecting rod 11. During the movement of the connecting rod 11, the moving rod 12 moves, and during the movement of the moving rod 12, the stop block 8 moves. Since the size of the stop block 8 is larger than the size of the first channel 5 and the size of the second channel 6, when the stop block 8 is directly in front of the first channel 5, the first channel 5 is closed; when the stop block 8 is directly in front of the second channel 6, the second channel 6 is closed. During the movement of the stop block 8, the cleaning plate 9 moves. Since one end of the cleaning plate 9 is attached to the side wall of the filter screen 7, the filter screen 7 is cleaned during the movement of the cleaning plate 9, that is, the impurities on the filter screen 7 are removed.

[0047] During the movement of the stop block 8, the second triangular block 21 moves. When the second triangular block 21 interacts with the first triangular block 20, the second triangular block 21 pushes the first triangular block 20 to move upward. During the upward movement of the first triangular block 20, the baffle 16 moves upward through the moving block 19. When the baffle 16 moves from the inlet 15 to the inside of the liquid box 13, the elastic element 18 is in a compressed state. The cleaning fluid inside the liquid box 13 flows through the inlet 15 to the outlet pipe 17. Since the outlet pipe 17 is located above the filter screen 7, the cleaning fluid discharged from the outlet pipe 17 flows onto the filter screen 7, facilitating the cleaning of the filter screen 7. The pneumatic telescopic rod 10 works to move the connecting rod 11. During the movement of the connecting rod 11, the moving rod 12 moves. During the movement of the moving rod 12, the stop block 8 moves. During the movement of the stop block 8, the cleaning plate 9 moves. Since one end of the cleaning plate 9 is attached to the side wall of the filter screen 7, the filter screen 7 is cleaned during the movement of the cleaning plate 9.

[0048] Example 2

[0049] The following technical features are added based on Embodiment 1:

[0050] A flue gas flow conversion device for a dust collection pipe of a sintering machine includes an inlet pipe 2 connected to a flexible hose 25, a control valve 26 installed on the flexible hose 25, an air inlet channel 27 on a moving rod 12 connected to the flexible hose 25, a cavity 28 on a baffle block 8, a connecting plate 29 fixedly connected to the baffle block 8, and an outlet pipe 30 fixedly connected to the connecting plate 29. The air inlet channel 27 is connected to the cavity 28, and the cavity 28 is connected to the outlet pipe 30. When cleaning impurities attached to the filter screen 7, the operator opens the control valve 26, and the gas inside the inlet pipe 2 enters the air inlet channel 27 through the flexible hose 25. The gas then enters the outlet pipe 30 through the air inlet channel 27 and the cavity 28, and is discharged through the outlet pipe 30. Since the outlet pipe 30 is tilted downwards relative to the filter screen 7, the gas discharged from the outlet pipe 30 blows the cleaning liquid and impurities on the filter screen 7 downwards, facilitating the cleaning of the filter screen 7.

[0051] Working principle: Since the flue gas contains impurities, when the flue gas enters the interior of the first channel 5 or the second channel 6, the impurities in the flue gas adhere to the filter screen 7. When it is necessary to clean the filter screen 7 of the first channel 5 or the filter screen 7 of the second channel 6.

[0052] The pneumatic telescopic rod 10 moves the connecting rod 11, which in turn moves the moving rod 12, which in turn moves the stop block 8. Since the size of the stop block 8 is larger than that of the first channel 5 and the second channel 6, when the stop block 8 is directly in front of the first channel 5, it closes the first channel 5; when the stop block 8 is directly in front of the second channel 6, it closes the second channel 6. During the movement of the stop block 8, the cleaning plate 9 moves. Since one end of the cleaning plate 9 is attached to the side wall of the filter screen 7, the movement of the cleaning plate 9 cleans the filter screen 7, removing impurities from it.

[0053] During the movement of the stop block 8, the second triangular block 21 moves. When the second triangular block 21 interacts with the first triangular block 20, the second triangular block 21 pushes the first triangular block 20 to move upward. During the upward movement of the first triangular block 20, the baffle 16 moves upward through the moving block 19. When the baffle 16 moves from the inlet 15 to the inside of the liquid box 13, the elastic element 18 is in a compressed state. The cleaning fluid inside the liquid box 13 flows through the inlet 15 to the outlet pipe 17. Since the outlet pipe 17 is located above the filter screen 7, the cleaning fluid discharged from the outlet pipe 17 flows onto the filter screen 7, facilitating the cleaning of the filter screen 7. The pneumatic telescopic rod 10 works to move the connecting rod 11. During the movement of the connecting rod 11, the moving rod 12 moves. During the movement of the moving rod 12, the stop block 8 moves. During the movement of the stop block 8, the cleaning plate 9 moves. Since one end of the cleaning plate 9 is attached to the side wall of the filter screen 7, the filter screen 7 is cleaned during the movement of the cleaning plate 9.

[0054] When the operator opens the control valve 26, the gas inside the smoke inlet pipe 2 enters the air inlet channel 27 through the hose 25. The gas then enters the air outlet pipe 30 through the air inlet channel 27 and the cavity 28, and is discharged through the air outlet pipe 30. Since the air outlet pipe 30 is tilted downwards relative to the filter screen 7, the gas discharged from the air outlet pipe 30 blows the cleaning liquid and impurities on the filter screen 7 downwards, making it easier to clean the filter screen 7.

[0055] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
