Description

Technical Field

[0001] This utility model belongs to the field of grate cooler duct technology, and in particular relates to a grate cooler duct structure. Background Technology

[0002] The duct structure of a grate cooler typically refers to the pipeline structure used to transport cooling air and other gases in a grate cooler system. It generally consists of the pipeline body, connecting components, supporting structure, and may include regulating valves, pressure measuring devices, etc. Its design purpose is to efficiently deliver cooling air to the designated location in the grate cooler to achieve rapid cooling of high-temperature clinker, while ensuring reasonable distribution and stable flow of air within the system, improving the cooling effect and overall operating efficiency of the grate cooler, and may also possess wear-resistant and high-temperature resistant properties to adapt to harsh working environments.

[0003] In the actual operation of the grate cooler duct, the internal filter block is responsible for filtering impurities and is of great importance. However, the existing duct structure design is poor, the filter block disassembly is difficult, the connection between the filter block and the duct is complicated, and they are mostly embedded or surrounded by multiple components. Once the filter block is damaged, maintenance personnel have to remove many surrounding parts before they can access the filter block. This is not only time-consuming and laborious, but also seriously slows down the replacement progress and greatly reduces the installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a duct structure for a grate cooler, which solves the technical problems mentioned in the background art by providing a connecting mechanism.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a duct structure for a grate cooler, including an upper cooling duct, on which a connecting mechanism and two configuration mechanisms are provided;

[0007] The connecting mechanism includes a filter block slidably connected to the inner wall of the upper cooling duct, a lower cooling duct slidably connected to the outer wall of the filter block, and retaining rings fixedly connected to the outer walls of both the upper and lower cooling ducts. A sealing groove and a sealing ring are fixedly connected to the two retaining rings at their closest points, and the sealing groove and sealing ring are compatible. A semi-hoop ring is provided on the outer wall of the two retaining rings, and a second semi-hoop ring is hinged to the inner wall of the first semi-hoop ring. Both retaining rings are compatible with the first and second semi-hoop rings. A rotating block is rotatably connected to the inner wall of the first semi-hoop ring, and a retaining groove is provided on the second semi-hoop ring. A screw is fixedly connected to the right side of the rotating block.

[0008] Furthermore, the screw is adapted to the slot, and a manual turntable is threaded onto the outer wall of the screw.

[0009] Furthermore, the configuration mechanism includes a connector fixedly connected to the top of the upper cooling duct, the inner wall of the connector having a sealing groove, and the bottom inner wall of the sealing groove having a plurality of strong springs fixedly connected.

[0010] Furthermore, a sealing push ring is fixedly connected to the top of several of the high-strength springs, and a sealing ring II is fixedly connected to the top of the sealing push ring.

[0011] Furthermore, the top of the connector has two notches, both of which communicate with the sealing movable groove, and the top inner wall of the sealing movable groove has two limiting grooves.

[0012] Furthermore, the inner walls of the two limiting grooves are slidably connected to limiting rings, the bottom of the limiting rings is in contact with the sealing push ring, and the inner wall of the limiting rings is provided with sealing grooves.

[0013] Furthermore, the sealing groove and the sealing ring are compatible, and a connecting pipe is fixedly connected to the top of the limiting ring.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the setting of a connecting mechanism, allows for the following operation steps when the filter block needs to be replaced: First, rotate the manual turntable on the outer wall of the screw. This releases the limiting effect of the upper half-hoop ring two on the outer wall of the screw, allowing half-hoop ring two to open with half-hoop ring one. When half-hoop ring one and half-hoop ring two are fully open, the upper and lower cooling air pipes inside can be separated, making it easy to replace the internal filter block. This design simplifies the cumbersome process of filter block installation and disassembly, thereby improving installation efficiency.

[0016] 2. This utility model, through its configuration mechanism, allows for easy installation of the device with a pipeline. First, the limiting ring at the top of the connecting pipe is inserted into the sealing groove through the notch on the connector. During insertion, the limiting ring pushes upwards against the sealing push ring within the sealing groove, simultaneously compressing the powerful spring on the sealing push ring. This allows the powerful spring to accumulate energy, providing power for subsequent reset operations. By continuously pushing the sealing push ring upwards, the limiting ring rotates to the limiting groove position within the connector. Then, the connecting pipe can be released. At this point, multiple powerful springs begin to reset, pushing the sealing push ring closer to the limiting ring on the connecting pipe, thus securing the limiting ring within the two limiting grooves. This completes the fixing of the connecting pipe. This design not only achieves a quick and stable connection between the device and the pipeline but also enhances the sealing performance of the connection point through the synergistic effect of the sealing push ring and powerful springs during the connection process. This effectively avoids potential leakage problems at the pipeline connection point and improves the overall system reliability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5As shown, this utility model is a duct structure for a grate cooler, including an upper cooling duct 1, on which a connecting mechanism 2 and two configuration mechanisms 3 are provided;

[0028] The connecting mechanism 2 includes a filter block 21 slidably connected to the inner wall of the upper cooling duct 1. The outer wall of the filter block 21 is slidably connected to the lower cooling duct 22. The outer walls of both the upper cooling duct 1 and the lower cooling duct 22 are fixedly connected to retaining rings 23. The ends of the two retaining rings 23 that are close to each other are fixedly connected to a sealing groove 24 and a sealing ring 25. The sealing groove 24 and the sealing ring 25 are compatible. The outer walls of the two retaining rings 23 are provided with a half-hoop 26. The inner wall of the half-hoop 26 is hinged with a second half-hoop 27. Both retaining rings 23 are compatible with the first half-hoop 26 and the second half-hoop 27. The inner wall of the half-hoop 26 is rotatably connected to a rotating block 28. The second half-hoop 27 is provided with a slot 29. The right side of the rotating block 28 is fixedly connected to a screw 291. The screw 291 is compatible with the slot 29. The outer wall of the screw 291 is threadedly connected to a manual turntable 292.

[0029] By setting the connecting mechanism 2, when it is necessary to replace the filter block 21, the operation steps are as follows: First, rotate the manual turntable 292 on the outer wall of the screw 291. At this time, the limiting effect of the upper half hoop 27 on the outer wall of the screw 291 can be released, so that the half hoop 27 and the half hoop 1 26 can be opened to each other. When the half hoop 1 26 and the half hoop 27 are fully opened, the upper cold air pipe 1 and the lower cold air pipe 22 inside can be separated. At this time, the filter block 21 inside can be easily replaced. This setting can simplify the cumbersome process of installing and disassembling the filter block 21, thereby improving the installation efficiency.

[0030] The configuration mechanism 3 includes a connector 31 fixedly connected to the top of the upper cooling air duct 1. The inner wall of the connector 31 is provided with a sealing movable groove 32. Several strong springs 33 are fixedly connected to the bottom inner wall of the sealing movable groove 32. A sealing push ring 34 is fixedly connected to the top of the several strong springs 33. A sealing ring 35 is fixedly connected to the top of the sealing push ring 34. Two notches 36 are opened at the top of the connector 31. Both notches 36 communicate with the sealing movable groove 32. Two limiting grooves 37 are opened at the top inner wall of the sealing movable groove 32. Limiting rings 38 are slidably connected to the inner walls of the two limiting grooves 37. The bottom of the limiting rings 38 is in contact with the sealing push ring 34. A sealing groove 39 is opened on the inner wall of the limiting rings 38. The sealing grooves 39 are adapted to the sealing ring 35. A connecting pipe 391 is fixedly connected to the top of the limiting rings 38.

[0031] By setting the configuration mechanism 3, when the device needs to be installed with the pipeline, the limiting ring 38 at the top of the connecting pipe 391 can be inserted into the sealing movable groove 32 through the notch 36 on the connector 31. During the insertion process, the limiting ring 38 will push the sealing push ring 34 in the sealing movable groove 32 upward, and at the same time compress the strong spring 33 on the sealing push ring 34, so that the strong spring 33 accumulates energy to provide power support for the subsequent reset operation. By continuously pushing the sealing push ring 34 upward, the limiting ring 38 can be rotated to the position of the limiting groove 37 in the connector 31. Next, the connecting pipe 391 can be loosened. At this time, multiple strong springs 33 begin to reset and push the sealing push ring 34, causing it to move closer to the limiting ring 38 on the connecting pipe 391, thereby limiting the limiting ring 38 within the two limiting grooves 37. This completes the fixation of the connecting pipe 391. Through this setting, not only is a quick and stable connection between the device and the pipeline achieved, but also the sealing performance at the connection point is enhanced by the synergistic effect of the sealing push ring 34 and the strong springs 33 during the connection process. This effectively avoids possible leakage problems at the pipeline connection point and improves the operational reliability of the entire system.

[0032] A specific application of this embodiment is as follows: When it is necessary to replace the filter block 21, the operation steps are as follows: First, rotate the manual turntable 292 on the outer wall of the screw 291. At this time, the limiting effect of the second half-hoop 27 on the outer wall of the screw 291 can be released, so that the second half-hoop 27 can open with the first half-hoop 26. When the first half-hoop 26 and the second half-hoop 27 are fully opened, the upper cold air pipe 1 and the lower cold air pipe 22 inside can be separated. At this time, the filter block 21 inside can be easily replaced. Through this setting, the cumbersome process of installing and disassembling the filter block 21 can be simplified, thereby improving the installation efficiency. If it is necessary to install the device with the pipeline, the limiting ring 38 at the top of the connecting pipe 391 can be inserted into the sealing movable groove 32 through the notch 36 on the connector 31. During the insertion process, the limiting ring 38 will squeeze the sealing movable groove upward. The sealing push ring 34 in the groove 32 compresses the powerful spring 33 on the sealing push ring 34, allowing the powerful spring 33 to accumulate energy and provide power support for the subsequent reset operation. By continuously pressing the sealing push ring 34 upward, the limiting ring 38 can be rotated to the position of the limiting groove 37 in the connector 31. Then, the connecting pipe 391 can be released. At this time, multiple powerful springs 33 begin to reset and push the sealing push ring 34, making it move closer to the limiting ring 38 on the connecting pipe 391, thereby limiting the limiting ring 38 in the two limiting grooves 37. This completes the fixation of the connecting pipe 391. Through this setting, not only is a fast and stable connection between the device and the pipeline achieved, but also the synergistic effect of the sealing push ring 34 and the powerful spring 33 during the connection process enhances the sealing performance of the connection, effectively avoiding possible leakage problems at the pipeline connection and improving the operational reliability of the entire system.
