Description

Technical Field

[0001] This utility model relates to the technical field of wet coke quenching systems, specifically to the linkage locking protection mechanism of wet coke quenching systems. Background Technology

[0002] In traditional wet quenching, high-temperature coke is ejected from the coke oven and transported by a quenching car to the quenching device for cooling with water spray. During the cooling process, a significant amount of latent heat in the red-hot coke is wasted, causing environmental pollution. Furthermore, the unstable moisture content of the coke affects product quality. Existing wet quenching systems lack interlocking protection mechanisms, often requiring manual operation, which results in the release of large amounts of steam and environmental impact. Therefore, an interlocking protection mechanism for the wet quenching system is designed to address these issues.

[0015] 1. Equipped with an installation cover, coke transport box, and controller, when the wet quenching system needs to be interlocked for protection, after the burning coal is collected inside the coke transport box, it needs to enter the spraying equipment for quenching. The second motor is started, and through the transmission mechanism on the second threaded rod, multiple second threaded rods are driven to move. The second threaded rods drive the coke transport box to enter the protective shell along the path of the guide rod. When the upper right side of the coke transport box contacts the controller, the telescopic rod is activated to retract, causing the installation cover to fall down and cover the upper end of the protective shell, thus realizing the interlocking protection mechanism.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a linkage locking protection mechanism for a wet quenching system, comprising a worktable 1, a protective shell 2, a mounting cover 3, a telescopic rod 4, a nozzle 5, a first threaded rod 6, a first motor 7, a folded corrugated pipe 8, a water tank 9, a first pipe 10, a filter pump 11, a second pipe 12, a liquid collection tank 13, a filter screen frame 14, a spring 15, a locking block 16, a locking groove 17, a fixing bolt 18, a nut 19, a coke transport box 20, a controller 21, a guide rod 22, a second threaded rod 23, and a second motor 24.

[0026] When implementing interlocking protection within the wet quenching system, for example, with... Figure 1 Appendix Figure 2 and attached Figure 3As shown, the upper end of the protective shell 2 is provided with a mounting cover 3. The front and rear ends of the mounting cover 3 are connected to telescopic rods 4. The left and right sides of the mounting cover 3 are provided with sliding grooves. The inside of the sliding grooves of the mounting cover 3 is connected to a nozzle 5. The inside of the protective shell 2 is provided with a coke transport box 20. The front and rear ends of the coke transport box 20 are connected to a guide rod 22 and a second threaded rod 23. The second threaded rod 23 is located behind the guide rod 22. The right end of the second threaded rod 23 is equipped with a second motor 24. After the coke is collected inside the coke transport box 20, it is necessary to transport the coke from the coke transport box 20 to the inside of the protective shell 2. At this time, the second motor 24 is started to drive the second threaded rod 23 to rotate. The outer side of the second threaded rod 23 is connected to the coke transport box 20 by a screw thread. The threads are connected in a spiral pattern. At the same time, the second threaded rod 23 is driven by a toothed belt and pulley, so that multiple second threaded rods 23 move synchronously. The second threaded rod 23 drives the coke box 20 to move to the right through the threads. Finally, the second threaded rod 23 drives the coke box 20 to enter the interior of the protective shell 2 along the path of the guide rod 22. At this time, the upper end of the coke box 20 is in contact with the controller 21 set on the upper left side of the protective shell 2, so that the controller 21 controls the telescopic rod 4 to retract. The telescopic rod 4 then drives the mounting cover 3 to move downward. The mounting cover 3 finally fits against the upper end of the workbench 1, so that the spray device inside the protective shell 2 can protect the coke spray from leakage and prevent it from affecting the external steam leakage.

[0027] When spraying coke inside a wet quenching system, for example, when applying... Figure 1 Appendix Figure 2 Appendix Figure 4 and attached Figure 5As shown, the upper middle part of the nozzle 5 is connected to the first threaded rod 6 by a thread. The rear end of the first threaded rod 6 is equipped with a first motor 7. The right end of the nozzle 5 is connected to a folded corrugated pipe 8, and the lower end of the folded corrugated pipe 8 is connected to a water tank 9. The lower end of the mounting cover 3 is equipped with a filter screen frame 14. The left and right sides of the filter screen frame 14 are equipped with springs 15 and locking blocks 16. The locking blocks 16 are located on the left and right sides of the springs 15 and form a sliding structure inside the left and right ends of the filter screen frame 14. The cross-section of the locking blocks 16 is L-shaped. The upper end of the locking blocks 16 is connected to the locking groove 17 by a locking method. The locking groove 17 is located at the lower end of the inner wall of the mounting cover 3. First, the nozzle 5 is started to absorb and spray water from the water tank 9 through the folded corrugated pipe 8. Then, the first motor 7 is started to drive the first threaded rod 6 to rotate. The outer thread of the first threaded rod 6 drives the nozzle 5 to move back and forth, so that the nozzle 5 moves against the protective shell. 2. The coke stored inside is sprayed evenly, but some water falls downwards during spraying. This water is guided downwards through the grid at the top of the collection tank 13 and collected inside the collection tank 13. At this time, the filter pump 11 is started to absorb and filter the water through the second pipe 12, and then transport it to the water tank 9 through the first pipe 10 for recycling. However, when the nozzle 5 sprays the coke, the steam and dust emitted by the coke will float upwards. At this time, the filter screen frame 14 will filter them to prevent dust from affecting the use of the nozzle 5. Since clogging will occur after long-term filtration, it is necessary to disassemble and clean it. Remove the nut 19 connected to the lower end of the fixing bolt 18, and then slide the locking block 16 to the left and right to squeeze the spring 15, so that the locking block 16 finally disengages from the locking groove 17, thereby realizing the overall disassembly and cleaning of the filter screen frame 14. This is the overall process and structure of the spraying inside the wet quenching system.
