Description

Technical Field

[0001] This utility model relates to the field of steel sintering, and in particular to a sintering flue ash discharge structure. Background Technology

[0002] During the steel sintering process, a large amount of dust-laden flue gas is generated when raw materials such as iron ore, fuel, and flux are roasted at high temperatures in the sintering machine. This flue gas needs to be transported to a dust collector for purification through a flue. During the flue transport and dust removal process, dust is deposited at the bottom of the flue and in the dust collector ash hopper due to gravity and airflow resistance, forming ash slag that affects flue gas exhaust. To discharge the dust material in the high negative pressure exhaust system while effectively preventing external air from entering the exhaust system, the system often uses double-layer ash discharge valves to discharge the dust material.

[0003] A search of Chinese patents revealed publication number CN220017402U, which discloses an ash removal structure for sintering flues. The structure includes: a central housing with a connector fixedly mounted at its bottom and an ash removal hole at its top, within which a flue ash removal pipe is fixedly mounted; and an ash removal assembly mounted on the connector, comprising a support rod, a disc, a hydraulic cylinder, a connecting rod, a first sealing plug, a first guide component, a vertical rod, a second sealing plug, and a discharge pipe. The support rod is fixedly installed at the bottom of the connector and its bottom end is fixedly connected to the disc. The hydraulic cylinder is fixedly installed at the top of the disc, and its hydraulic rod is fixedly connected to the connecting rod, with the top end of the connecting rod fixedly connected to the first sealing plug. This invention offers the following advantages and effects: compared to switching between upper and lower sealing valves, it is simpler to operate and less prone to errors.

[0004] The existing unloading structure does not have an anti-clogging function. The double-layer ash discharge valve is conical. During ash discharge, the middle of the double-layer ash discharge valve is narrow. During ash discharge, ash and slag accumulate inside the ash discharge valve, which can easily cause blockage and affect normal ash discharge. Tools are needed to clear the blockage, which increases the workload, reduces practicality, and is inconvenient to use. In order to solve the above problems, we propose an ash discharge structure for sintering flue. Utility Model Content

[0005] The purpose of this invention is to provide a sintering flue ash discharge structure, which has the advantage of being anti-clogging.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sintering flue ash removal structure, including a connecting pipe, an ash removal mechanism is provided at the top and bottom of the connecting pipe, a telescopic mechanism is provided at the top of the ash removal mechanism, a dual-axis motor is bolted to the surface of the connecting pipe, a first pulley is fixedly sleeved at the output end of the dual-axis motor, a rotating shaft is rotatably sleeved on the inner wall of the connecting pipe, a rotating rod is bolted to the surface of the rotating shaft, two first eccentric blocks are fixedly sleeved on the surface of the rotating shaft, two second pulleys are fixedly sleeved on the surface of the rotating shaft, and a transmission belt is connected between the surfaces of the first pulleys and the second pulleys.

[0007] By adopting the above technical solution, the rotation of the dual-shaft motor drives the rotating shaft to rotate, which in turn causes the first eccentric block and the rotating rod to rotate. The rotation of the first eccentric block generates vibration, and the rotation of the rotating rod disperses the ash and slag, preventing the ash and slag from accumulating and caking. This method can prevent blockage, ensure smooth ash discharge, reduce workload, and facilitate use.

[0008] The present invention is further configured such that: a second eccentric block is fixedly sleeved at both ends of the rotating shaft; two toothed rings are fixedly sleeved on the surface of the rotating shaft; a toothed plate is slidably connected to the inner wall of the second eccentric block, and the toothed rings and the toothed plate mesh with each other; a fixing bolt is rotatably connected to the top of the toothed plate, and the fixing bolt is threadedly connected to the inner wall of the second eccentric block.

[0009] By adopting the above technical solution, the toothed plate is disengaged from the toothed ring by loosening the nut and rotating the fixing bolt. Then, the second eccentric block is rotated to the required position, and the fixing bolt is tightened to make the toothed plate and toothed ring press and mesh together to fix them. This changes the included angle between the two eccentric blocks, thereby adjusting the vibration amplitude and making it suitable for different situations, ensuring smooth ash unloading.

[0010] The present invention is further configured such that: the ash unloading mechanism includes an ash unloading hopper, the ash unloading hopper is connected to a connecting pipe, a rotating shaft is rotatably sleeved on the inner wall of the ash unloading hopper, a baffle is bolted to the surface of the rotating shaft, a transmission rod is fixedly sleeved on one end of the rotating shaft, a cylinder is hinged to the other end of the transmission rod, and a fixing plate is hinged to the other end of the cylinder, and the fixing plate is bolted to the surface of the ash unloading hopper.

[0011] By adopting the above technical solution and setting up an ash unloading mechanism, ash unloading can be achieved without stopping the machine, which is convenient for ash unloading.

[0012] The present invention is further configured such that: the telescopic mechanism includes two connecting frames, and the bottom connecting block communicates with the top of the top ash hopper; a telescopic cover is bolted between the connecting frames; multiple fixing rods are bolted to the top of the bottom connecting frame; a telescopic rod is slidably sleeved on the inner wall of the fixing rod; and the top of the telescopic rod is bolted to the bottom of the top connecting frame; a spring is provided between the inner wall of the telescopic rod and the fixing rod.

[0013] By adopting the above technical solution and setting up a telescopic mechanism, vibration can be facilitated.

[0014] The present invention is further configured such that: the surface of the connecting pipe is bolted to a protective shell, and the dual-axis motor is located inside the protective shell.

[0015] The above technical solution protects the dual-shaft motor by setting up a protective shell.

[0016] The present invention is further configured such that a nut is threaded onto the surface of the fixing bolt.

[0017] By using the above technical solution, nuts are used to secure the fixing bolts and prevent them from loosening.

[0018] The present invention is further configured such that: two support plates are bolted to the surface of the connecting pipe, and the support plates are rotatably sleeved with the output end of the dual-axis motor.

[0019] By adopting the above technical solution, the output end of the dual-axis motor is fixed by setting a support plate to ensure stability.

[0020] The present invention is further configured such that a sealing ring is embedded in the surface of the baffle.

[0021] By adopting the above technical solution and setting a sealing ring, ash leakage is prevented and airtightness is ensured.

[0022] In summary, this utility model has the following beneficial effects: 1. This utility model uses a dual-shaft motor to drive a rotating shaft to rotate. The rotation of the rotating shaft causes the first eccentric block and the rotating rod to rotate. The rotation of the first eccentric block generates vibration, and the rotation of the rotating rod disperses the ash and slag, preventing the ash and slag from accumulating and caking. This method can prevent blockage, ensure smooth ash discharge, reduce workload, and is convenient to use. 2. This utility model allows the toothed plate to disengage from the toothed ring by loosening the nut and rotating the fixing bolt. Then, the second eccentric block is rotated to the desired position, and the fixing bolt is tightened to press and engage the toothed plate and toothed ring to fix them in place. This changes the included angle between the two eccentric blocks, thereby adjusting the vibration amplitude and making it suitable for different situations, ensuring smooth ash unloading.

Then, the cylinder 19 retracts, driving the transmission rod 18 to rotate the rotating shaft 16 in the opposite direction. The rotation of the rotating shaft 16 in the opposite direction closes the baffle 17. Then, open the bottom cylinder 19 to open the bottom baffle 17 and discharge the ash. After discharge, close the bottom baffle 17 to complete the unloading and achieve ash discharge without stopping the machine. During unloading, the dual-shaft motor 4 is turned on. The rotation of the dual-shaft motor 4 drives the first belt pulley 5 to rotate, which in turn drives the transmission belt 10 to rotate. The transmission belt 10 then drives the second belt pulley 9 to rotate, which in turn drives the rotating rod 7. The first eccentric block 8 and the second eccentric block 11 rotate, generating vibration. This vibration increases the fluidity of the ash and slag. The rotation of the rotating rod 7 disperses the ash and slag, preventing it from accumulating and caking, thereby preventing blockage. Loosen the nut 27, rotate the fixing bolt 14 to disengage the toothed plate 13 from the toothed ring 12, then rotate the second eccentric block 11 to the desired position, and then tighten the fixing bolt 14 to press and engage the toothed plate 13 and the toothed ring 12 to fix them together, thereby changing the included angle between the two eccentric blocks and thus adjusting the vibration amplitude.
