Description

Technical Field

[0001] This utility model belongs to the technical field of cement production equipment, specifically relating to a snowman pusher device for a grate cooler. Background Technology

[0002] In the production of cement clinker, cooling devices are required. Currently, grate coolers are the most commonly used in the market. However, grate coolers often encounter the problem that the grates cannot push the clinker away in time, causing it to accumulate higher and higher, resulting in a "snowman" phenomenon. If the "snowman" phenomenon is not addressed promptly, it can have serious consequences for equipment and production.

[0003] When a "snowman" phenomenon forms inside the grate cooler, it is usually cleaned using a snowman-pushing device. Since the pushing box of the snowman-pushing device is outside the grate cooler, while the "snowman" is inside, the grate cooler contains not only high-temperature materials but also high-temperature, high-pressure gas. When the pusher head of the snowman-pushing device moves back and forth through the grate cooler wall, it creates positive pressure inside the grate cooler. If the pusher head and the grate cooler wall are not effectively sealed, the high-temperature materials and gas inside the grate cooler will spray out through the gap between the pusher head and the grate cooler wall. This not only affects the normal operation of the equipment but also poses a safety hazard. Utility Model Content

[0004] This utility model provides a snowman-pushing device for a grate cooler, which at least solves some of the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A snowman-pushing device for a grate cooler includes a pusher frame, a pusher device disposed within the pusher frame, a pusher head slidably disposed within the pusher frame and connected to the pusher device, a sealing mechanism disposed on the pusher frame for sealing the pusher head, and a connecting mechanism disposed on the sealing mechanism and connected to the grate cooler; the pusher head slidably passes through the sealing mechanism and the connecting mechanism.

[0007] Furthermore, the sealing mechanism includes a sealing mounting frame disposed on the pusher frame and connected to the connecting mechanism, a plurality of graphite blocks disposed within the sealing mounting frame and distributed around the pusher head, and a pressing mechanism rotatably disposed on the sealing mounting frame and connected to the graphite blocks.

[0008] Furthermore, the clamping mechanism includes a clamping stud rotatably mounted on the sealing mounting bracket, and several clamping plates rotatably mounted on the clamping stud and connected to the graphite block.

[0009] Furthermore, the clamping plate is provided with a connecting block, and the clamping plate is rotatably mounted on the clamping stud through the connecting block.

[0010] Furthermore, the sealed mounting bracket is provided with a graphite mounting groove that is compatible with the graphite block, and the graphite block is installed in the graphite mounting groove.

[0011] Furthermore, the pushing device includes a hydraulic mounting base on the pushing frame, a hydraulic cylinder on the hydraulic mounting base, and a connecting plate on the output end of the hydraulic cylinder and connected to the push head.

[0012] Furthermore, the push frame is provided with a relief groove that is adapted to the output end of the hydraulic cylinder, and the output end of the hydraulic cylinder passes through the relief groove and connects to the connecting plate.

[0013] Furthermore, the inner walls on both sides of the pusher are provided with sliding grooves that are compatible with the pusher head. The pusher head is slidably installed between the two sliding grooves and slides along the length of the sliding grooves.

[0014] Furthermore, the connecting mechanism includes a connecting seat welded to the grate cooler, a first sealing flange disposed on the connecting seat, and a second sealing flange disposed on the sealing mechanism and adapted to the first sealing flange, wherein the second sealing flange and the first sealing flange are connected by bolts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model features a simple structure, scientific and reasonable design, and convenient use. The pusher frame facilitates the installation of the pusher device, pusher head, and sealing mechanism. The pusher device moves the pusher head within the pusher frame, allowing it to pass through the sealing mechanism and connecting mechanism and enter the grate cooler to push away the "snowman." After cleaning the "snowman," the pusher device returns the pusher head to its initial position. During the pusher head's movement, the sealing mechanism seals it, preventing high-temperature materials and gases from escaping through the gap between the pusher head and the pusher frame when positive pressure is applied, thus preventing safety hazards. The connecting mechanism connects the sealing mechanism to the outer wall of the grate cooler at one end and seals it at the other, facilitating the connection between the sealing mechanism and the outer wall of the grate cooler. This also prevents high-temperature materials and gases from escaping through the gap between the sealing mechanism and the outer wall of the grate cooler. Attached Figure Description

[0031] Example 1.

[0032] like Figure 1-8 As shown, the present invention provides a snowman pushing device for a grate cooler, including a pusher frame 1, a pusher device disposed within the pusher frame 1, a pusher head 2 slidably disposed within the pusher frame 1 and connected to the pusher device, a sealing mechanism disposed on the pusher frame 1 for sealing the pusher head 2, and a connecting mechanism disposed on the sealing mechanism and connected to the grate cooler 19; the pusher head 2 slidably passes through the sealing mechanism and the connecting mechanism.

[0033] In this invention, the pusher frame 1 facilitates the installation of the pusher device, pusher head 2, and sealing mechanism. The pusher device moves the pusher head 2 within the pusher frame 1, allowing it to pass through the sealing mechanism and connecting mechanism and enter the grate cooler 19 to push away the "snowman." After cleaning the "snowman," the pusher device returns the pusher head 2 to its initial position. During the movement of the pusher head 2, the sealing mechanism seals it, preventing high-temperature materials and gases from escaping through the gap between the pusher head 2 and the pusher frame 1 when positive pressure is applied, thus preventing safety hazards. One end of the connecting mechanism is connected to the grate cooler 19, and the other end is sealed to the sealing mechanism. The connecting mechanism facilitates the connection between the sealing mechanism and the outer wall of the grate cooler 19, and also seals the space between them, preventing high-temperature materials and gases from escaping through the gap between the sealing mechanism and the outer wall of the grate cooler 19.

[0034] The outer wall of the grate cooler 19 of this utility model is provided with a cleaning clearance groove (not shown in the figure) that is adapted to the pusher 2, and the pusher 2 is slidably disposed in the cleaning clearance groove.

[0035] Example 2.

[0036] like Figure 1-8As shown, the present invention provides a snowman pushing device for a grate cooler, including a pusher frame 1, a pusher device disposed within the pusher frame 1, a pusher head 2 slidably disposed within the pusher frame 1 and connected to the pusher device, a sealing mechanism disposed on the pusher frame 1 for sealing the pusher head 2, and a connecting mechanism disposed on the sealing mechanism and connected to the grate cooler 19; the pusher head 2 slidably passes through the sealing mechanism and the connecting mechanism.

[0037] The sealing mechanism includes a sealing mounting frame 3 mounted on the pusher frame 1 and connected to the connecting mechanism, a plurality of graphite blocks 4 disposed within the sealing mounting frame 3 and distributed around the pusher head 2, and a pressing mechanism rotatably mounted on the sealing mounting frame 3 and connected to the graphite blocks 4.

[0038] In this embodiment 2, one end of the sealing mounting frame 3 is fixedly connected to the push frame 1, and the other end is connected to the connecting mechanism. Graphite blocks 4 are placed inside the sealing mounting frame 3. The sealing mounting frame 3 also facilitates the installation of graphite blocks 4. The graphite blocks 4 are distributed around the push head 2, thus sealing the gap between the push frame 1 and the push head 2, preventing high-temperature materials and gases from being ejected from the gap when the snowplow device experiences positive pressure. The pressing mechanism presses the graphite blocks 4 firmly onto the push head 2 during use, ensuring a tight fit between the graphite blocks 4 and the push head 2. The push head 2 of this invention has a rectangular structure, as shown... Figure 4 As shown, the graphite blocks 4 of this utility model are preferably four, and the four graphite blocks 4 are distributed in a rectangular structure on the outside of the pusher head 2. When in use, the graphite blocks 4 are tightly attached to the outer wall of the pusher head 2, thereby playing a role in sealing and lubrication.

[0039] Example 3.

[0042] The clamping mechanism includes a clamping stud 5 rotatably mounted on the sealing mounting bracket 3, and several clamping plates 6 rotatably mounted on the clamping stud 5 and connected to the graphite block 4.

[0043] In this embodiment 3, the clamping stud 5 is threadedly connected to the sealing mounting bracket 3. The clamping plate 6 is rotatably mounted on the clamping stud 5 and connected to the graphite block 4. During use, the clamping stud 5 is manually rotated, causing it to push the clamping plate 6 within the sealing mounting bracket 3. The clamping plate 6 then pushes the graphite block 4, bringing it into contact with the pusher head 2. During operation, the graphite block 4 directly contacts the outer wall of the pusher head 2, thus providing sealing and lubrication. Simultaneously, the clamping plate 6, under the action of the clamping stud 5, presses the graphite block 4 tightly, ensuring close contact between the graphite block 4 and the outer wall of the pusher head 2. Because the clamping plate 6 and the clamping stud 5 are rotatably connected, the clamping plate 6 will not rotate with the clamping stud 5.

[0044] The sealing mounting bracket 3 of this utility model has several threaded holes that are compatible with the clamping studs 5, and the clamping studs 5 are threadedly connected to the threaded holes.

[0073] like Figure 7 As shown, a graphite packing 18 is filled between the first sealing flange 15 and the second sealing flange 16 of this utility model. Specifically, the first sealing flange 15 is provided with a boss, and the second sealing flange 16 is provided with an insert groove adapted to the boss. The graphite packing 18 is installed in the insert groove. When the first sealing flange 15 and the second sealing flange 16 are connected, the boss is located in the insert groove and squeezes the graphite packing 18, so that the graphite packing 18 can be fixed between the first sealing flange 15 and the second sealing flange 16. Since the graphite packing 18 is in close contact with the outer wall of the pusher 2 during operation, it plays a role in sealing and lubrication.

[0074] Example 10.

[0075] like Figure 1-8 As shown, the present invention provides a snowman pushing device for a grate cooler, including a pusher frame 1, a pusher device disposed within the pusher frame 1, a pusher head 2 slidably disposed within the pusher frame 1 and connected to the pusher device, a sealing mechanism disposed on the pusher frame 1 for sealing the pusher head 2, and a connecting mechanism disposed on the sealing mechanism and connected to the grate cooler 19; the pusher head 2 slidably passes through the sealing mechanism and the connecting mechanism.

[0077] The connecting seat 14 is provided with a push head relief groove 17 that is adapted to the push head 2.

[0078] In this embodiment 10, the connecting seat 14 is provided with a push head relief groove 17 that is adapted to the push head 2. The push head relief groove 17 can facilitate the push head to make way, thereby facilitating the push head 2 to remove the "snowman".

[0079] In this invention, the graphite block 4 is preferably made of graphite packing.

[0080] like Figure 8 As shown, the push frame 1 of this utility model includes a base plate 20, a support column 21 disposed on the base plate 20, and a push head mounting seat 23 disposed on the support column 21. Specifically, a hydraulic mounting seat 9 is mounted on the base plate 20, and a clearance groove 12 and a sliding groove 13 are disposed on the push head mounting seat 23. In this embodiment, the push head mounting seat 23 has a U-shaped structure, and the sliding groove 13 is disposed on the inner walls of both sides of the push frame 1. The push head 2 is slidably mounted between the two sliding grooves 13 and slides along the length direction of the sliding groove 13. The sliding groove 13 can facilitate the limiting and guiding of the push head 2.

[0081] Working principle

[0082] In use, one end of the connecting seat 14 is welded to the outer wall of the grate cooler 19, and the pusher clearance groove 17 is aligned with the cleaning clearance groove. At the same time, the sealing mounting frame 3 and the connecting seat 14 are connected by the second sealing flange 16 and the first sealing flange 15. Since the graphite block 4 is installed in the sealing mounting frame 3, when the graphite block 4 is working, it contacts the outer wall of the pusher 2, which plays a sealing and lubricating role. At the same time, by manually rotating the clamping stud 5, the clamping stud 5 pushes the clamping plate 6 to move within the sealing mounting frame 3. The clamping plate 6 pushes the graphite block 4 to move, so that the graphite block 4 is pressed between the clamping plate 6 and the pusher 2, thereby ensuring that the graphite block 4 and the clamping plate 6 are in close contact. In this way, when the pusher 5 moves back and forth under the drive of the hydraulic cylinder 10, it can prevent the leakage of high-temperature materials and high-temperature gases inside the grate cooler 19.

[0083] The hydraulic cylinder 10 and hydraulic station used in this utility model are existing technologies and can be purchased and used directly on the market. Therefore, the structure, principle and circuit of the hydraulic cylinder 10 and hydraulic station will not be described in detail here.
