Description

Technical Field

[0001] This invention relates to the field of annular cooler technology, and more specifically, to a water seal groove side plate structure and usage method for a sintering machine annular cooler. Background Technology

[0002] In response to the national call for energy conservation and emission reduction, most industries in the metallurgical sector have adopted new water-sealing technologies to upgrade sintering ring coolers, such as... Figure 1 As shown, the modification significantly improves the efficiency of flue gas waste heat recovery and utilization in the annular cooler. The upper and lower sealing devices of the annular cooler trolley 6 are the key to the sealing technology of the entire annular cooler. Due to the long-term operation of the sintering machine under high temperature and high dust conditions, siltation occurs in the water seal grooves of the upper and lower sealing devices. In particular, the upper water seal groove, due to its integral design and lack of effective drainage outlets, often suffers from severe water accumulation, even affecting production. Currently, the common method is to cut open the side plate of the water seal groove for siltation and then weld it back. This troubleshooting method is time-consuming, labor-intensive, inefficient, and the long maintenance time cannot meet the needs of high-paced production. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a sintering machine annular cooler water seal trough side plate structure and usage method, which greatly improves the efficiency of cleaning the upper water seal trough, reduces the labor intensity of operators, reduces the number of welding personnel required, and lowers labor and auxiliary material costs.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A side plate structure for a water seal trough in a sintering machine ring cooler includes a fixed side plate and a movable side plate. The fixed side plate is the outer side plate of the upper water seal trough of the outer ring. The fixed side plate is provided with a sludge discharge port. The movable side plate is detachably connected to the outer side of the fixed side plate and closes the sludge discharge port.

[0006] In one embodiment, the fixed side plate is provided with a first sealing mounting groove on the side facing the movable side plate. The first sealing mounting groove is distributed along the left and right outer sides and the bottom outer side of the sludge discharge port. The movable side plate is provided with a second sealing mounting groove that is adapted to the first sealing mounting groove. When the fixed side plate is connected to the movable side plate, the first sealing mounting groove and the second sealing mounting groove form a mounting cavity. A sealing strip is provided in the mounting cavity.

[0007] In one embodiment, the fixed side plate and the movable side plate are locked by bolts. The fixed side plate has multiple locking screw holes along the outer side of the sludge discharge port, and the movable side plate has multiple fixing through holes that cooperate with the locking screw holes. The bolts pass through the fixing through holes and connect with the locking screw holes to fix the fixed side plate and the movable side plate.

[0008] In one embodiment, a docking block is provided on the side of the movable side plate facing the sludge discharge port. The shape and size of the docking block are the same as the shape and size of the sludge discharge port. When the fixed side plate is connected to the movable side plate, the docking block is embedded in the sludge discharge port to close it.

[0009] In one embodiment, a pad is provided on the circumferential side of the docking block, and the docking block is interference-fitted with the sludge discharge port.

[0010] In one embodiment, the docking block has a connecting through hole that penetrates the movable side plate and the docking block. The connecting through hole communicates with the water seal groove, and an observation window is sealed inside the connecting through hole in one embodiment.

[0011] In one embodiment, the sludge discharge port is located on the side of the water seal trough at its lowest horizontal position, allowing for direct observation of the sludge accumulation within the water seal trough.

[0012] In one embodiment, a detection baffle and an infrared sensor are also provided in the connecting through hole. The detection baffle is located inside the observation window, and there is a gap of 1-5mm between the detection baffle and the observation window. The infrared sensor is located outside the observation window, and the infrared sensor emits infrared light towards the detection baffle. The infrared light is perpendicular to the observation window.

[0013] The following is a method of using the side plate structure of the water seal groove in the annular cooler of a sintering machine:

[0014] During normal production, the movable side plate covers the sludge discharge port of the fixed side plate, and the movable side plate is fixedly connected to the fixed side plate.

[0015] During maintenance and dredging, close the cooling water valve, drain all the cooling water from the water seal trough, remove the movable side plate to expose the sludge discharge port, discharge the sludge from the water seal trough through the discharge port, clean the mating surfaces of the fixed side plate and the movable side plate and the sealing strip, reinstall the movable side plate, test for leaks, and accept the maintenance results.

[0016] In one embodiment, during normal production, the siltation in the water seal tank is checked through an observation window.

[0017] In summary, the present invention has the following beneficial effects:

[0018] This invention improves upon existing water seal tanks in annular coolers by adding one or more sludge discharge ports, which are then sealed by movable side plates. Since the fixed and movable side plates are detachable, only the movable side plates need to be removed when cleaning sludge. After cleaning, the movable side plates can be reinstalled, and the water seal tank can be reused. This invention significantly improves the efficiency of cleaning the upper water seal tank, reduces the labor intensity of operators, reduces the need for welding personnel, and lowers labor and material costs.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.

[0027] like Figure 1-5 As shown, a side plate structure for a water seal trough of a sintering machine ring cooler includes a fixed side plate 2 and a movable side plate 3. The fixed side plate 2 is the outer side plate of the upper water seal trough 1 of the outer ring. The fixed side plate 2 is provided with a sludge discharge port 7. The movable side plate 3 is detachably connected to the outer side of the fixed side plate 2 and closes the sludge discharge port 7.

[0028] This invention improves upon the existing water seal tank 1 of an annular cooler by adding one or more sludge discharge ports 7, which are then sealed by movable side plates 3. Since the fixed side plates 2 and the movable side plates 3 are detachable, only the movable side plates 3 need to be removed when cleaning sludge. After cleaning, the movable side plates 3 can be reinstalled, and the water seal tank 1 can be reused. This invention greatly improves the efficiency of cleaning operations in the upper water seal tank 1, reduces the labor intensity of operators, reduces the number of welders required, and lowers labor and material costs.

[0029] Furthermore, the fixed side plate 2 is provided with a first sealing mounting groove on the side facing the movable side plate 3. The first sealing mounting groove is distributed along the left, right, and bottom outer sides of the drainage port 7. The movable side plate 3 is provided with a second sealing mounting groove that matches the first sealing mounting groove. When the fixed side plate 2 and the movable side plate 3 are connected, the first sealing mounting groove and the second sealing mounting groove form a mounting cavity. A sealing strip 4 is provided in the mounting cavity. The sealing strip 4 seals the gap between the fixed side plate 2 and the movable side plate 3 to prevent water leakage.

[0030] Furthermore, the fixed side plate 2 and the movable side plate 3 are locked together by bolts 5. The fixed side plate 2 has multiple locking screw holes along the outer side of the sludge discharge port 7, and the movable side plate 3 has multiple fixing through holes that cooperate with the locking screw holes. The bolts 5 pass through the fixing through holes and connect with the locking screw holes to fix the fixed side plate 2 and the movable side plate 3.

[0031] Furthermore, in order to improve the sealing effect of the movable side plate 3 on the sludge discharge port 7, a docking block is provided on the side of the movable side plate 3 facing the sludge discharge port 7. The shape and size of the docking block are the same as the shape and size of the sludge discharge port 7. When the fixed side plate 2 is connected to the movable side plate 3, the docking block is embedded in the sludge discharge port 7, initially sealing the sludge discharge port 7. In conjunction with the sealing strip 4, the sealing degree is improved.

[0032] Furthermore, a padding layer is provided on the circumferential side of the docking block, and the docking block is interference-fitted with the sludge discharge port 7.

[0033] To facilitate observation of the siltation in the water seal trough 1, the connecting block is provided with a through hole 8 that penetrates the movable side plate 3 and the connecting block. The through hole 8 is connected to the inside of the water seal trough 1, and an observation window 9 is sealed inside the through hole 8 to facilitate direct observation of the condition inside the water seal trough 1 from outside the movable side plate 3.

[0034] Furthermore, the sludge discharge port 7 is located on the side of the water seal trough 1 at its lowest horizontal position, allowing for a direct observation of the sludge accumulation within the water seal trough 1.

[0035] Furthermore, a detection baffle 11 and an infrared sensor 10 are also provided inside the connecting through hole 8. The detection baffle 11 is located inside the observation window 9, and there is a gap of 1-5mm between the detection baffle 11 and the observation window 9. The infrared sensor 10 is located outside the observation window 9, and the infrared sensor 10 emits infrared light towards the detection baffle 11. The infrared light is perpendicular to the observation window 9.

[0036] It is easy to understand that the infrared light emitted by the infrared sensor 10 is perpendicular to the observation window 9. Therefore, after the infrared light is reflected by the detection baffle 11, it can return to the infrared sensor 10 along the original path. There is a certain height difference between the infrared sensor 10, the detection baffle 11 and the inner bottom surface of the connecting through hole 8. This height difference is the allowable silt thickness. When the silt thickness exceeds this height difference, the detection baffle 11 will be blocked, the infrared sensor 10 will not be able to detect the signal, and an alarm for excessive silt will be issued.

[0037] Based on the above-described structure of the water seal groove side plate of the sintering machine annular cooler, the present invention also provides its method of use, as follows:

[0038] During normal production, the movable side plate 3 covers the sludge discharge port 7 of the fixed side plate 2, and the movable side plate 3 is fixedly connected to the fixed side plate 2.

[0039] During maintenance and dredging, close the cooling water valve, drain all the cooling water from the water seal trough 1, remove the movable side plate 3 to expose the sludge discharge port 7, discharge the sludge from the water seal trough 1 through the sludge discharge port 7, clean the mating surfaces of the fixed side plate 2 and the movable side plate 3 and the sealing strip 4, and finally reinstall the movable side plate 3, test for leaks, and accept the maintenance results.

[0040] Furthermore, during normal production, the siltation status within the water seal tank 1 is confirmed through observation window 9. The above description is merely a preferred embodiment of the present invention, and 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 principle of the present invention should also be considered within the scope of protection of the present invention.
