Description

Technical Field

[0001] This utility model relates to the field of grate cooler technology, and more specifically, to a grate plate for a grate cooler with anti-clogging function. Background Technology

[0002] The grate cooler is a crucial main piece of equipment in the clinker calcination system of a cement plant. Its primary function is to cool and transport cement clinker, while also providing hot air for the rotary kiln and precalciner. It is a key component of the calcination system's heat recovery. The grate plate is the main part of the grate cooler, and it is mostly a one-piece molded structure. The grate plate has slots for high-pressure cold air to pass through and cool the cement. A certain thickness of pebbles is typically laid on the grate plate. The injected cold air passes through the grate slots and pebbles, rapidly cooling the clinker.

[0003] However, the movement of the grate during operation inevitably causes pebbles and clinker to mix and get stuck in the grate gaps. The one-piece molded grate makes it difficult to remove the pebbles and clinker stuck in the grate gaps, affecting the cooling of the clinker.

[0004] Therefore, we have made improvements and proposed a grate plate for a grate cooler with anti-clogging function. Utility Model Content

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Please refer to Figure 1 and Figure 2 A grate plate for a grate cooler with anti-clogging function includes a grate plate 1. The inner wall of the grate plate 1 is slidably connected with grate bars 7 arranged at equal intervals. Both sides of the grate bars 7 are arc-shaped. Both sides of the grate bars 7 are rotatably connected with conveying rods 8. The surface of the conveying rods 8 is provided with spiral grooves 24. Through the setting of the spiral grooves 24, the rotation of the conveying rods 8 and the spiral grooves 24 can push the pebbles and clinker stuck between the two grate bars 7 and the two conveying rods 8, thereby pushing out the pebbles and clinker, avoiding the pebbles and clinker from getting stuck in the grate gaps and affecting the cooling of the conveyed material.

[0030] For further details, please refer to... Figure 1 and Figure 2 One end of the conveying rod 8 is fixedly connected to a fixing block 9, and the inner wall of the grate 1 is fixedly connected to an installation rod 10. The installation rod 10 passes through the surface of the fixing block 9 and slides inside the fixing block 9 to guide the movement of the conveying rod 8. At the same time, the installation rod 10 provides an installation point for the other end of the grate 7, while avoiding obstruction of the discharge of pebbles and clinker, thus ensuring the smooth operation of the device.

[0031] For further details, please refer to... Figure 3 A first connecting plate 5 and a second connecting plate 6 are fixedly connected to both sides of the grate 1. The cross-section of both the first connecting plate 5 and the second connecting plate 6 is U-shaped. The second connecting plate 6 can be inserted into the first connecting plate 5, thereby sealing and shielding the gap between the two grate plates 1 to prevent clinker and pebbles from falling through the gap between the two grate plates 1. A cleaning mechanism is provided inside the grate plate 1. The cleaning mechanism includes mounting shells 15 arranged at equal intervals. The surface of the mounting shells 15 is slidably connected to the inside of the grate plate 1. One end of the grate bar 7 is rotatably connected to a connecting shaft. 17. The connecting shaft 17 passes through the interior of the mounting housing 15 and is rotatably connected to the interior of the mounting housing 15. One end of each of the two conveying rods 8 is fixedly connected to a drive shaft 19, which also passes through the interior of the mounting housing 15 and is rotatably connected to the interior of the mounting housing 15. A second gear 16 is fixedly connected to the surface of the connecting shaft 17, and a third gear 18 is fixedly connected to the surface of each of the two drive shafts 19. Both third gears 18 are meshed with the second gear 16, so that when the connecting shaft 17 rotates, it can synchronously drive the conveying rods 8 on both sides to rotate.

[0032] The grate plate 1 is rotatably connected to a rotating shaft 3 that passes through the surface of the grate plate 1. The rotating shaft 3 passes through the surface of the mounting shell 15 and slides against the interior of the mounting shell 15. The inner wall of the mounting shell 15 is rotatably connected to a mounting sleeve 12. The rotating shaft 3 passes through the surface of the mounting sleeve 12 and slides against the interior of the mounting sleeve 12. The mounting sleeve 12 and the rotating shaft 3 are connected by a spline, so that when the rotating shaft 3 rotates, it can synchronously drive the mounting sleeve 12 to rotate without affecting the sliding between the rotating shaft 3 and the mounting sleeve 12, thus ensuring the smooth operation of the device.

[0033] The surface of the mounting sleeve 12 is fixedly connected to the first bevel gear 13, and the surface of the connecting shaft 17 is fixedly connected to the second bevel gear 14. The surface of the second bevel gear 14 meshes with the surface of the first bevel gear 13. The mounting sleeve 12 and the first bevel gear 13 in the two adjacent mounting shells 15 are arranged in opposite directions in the two mounting shells 15, so that the two conveying rods 8 on both sides of the grate rotate in opposite directions. This allows the conveying rods 8 to smoothly discharge the pebbles and clinker stuck in the grate when they rotate, ensuring the smooth operation of the device.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, a first gear 4 is fixedly connected to one end of the rotating shaft 3 located outside the grate plate 1, and a rack 11 is fixedly connected to the bottom of the second docking plate 6. The surface of the rack 11 meshes with the surface of the first gear 4. Thus, through the arrangement of the rack 11 and the first gear 4, when two adjacent grates 1 move relative to each other, the rotating shaft 3 can be smoothly driven to rotate through the meshing of the rack 11 and the first gear 4, thereby driving the conveying rod 8 to rotate and realizing the smooth conveying and transportation of pebbles and clinker.

[0035] Furthermore, such as Figure 4 As shown, a movable plate 20 is slidably connected inside the grate 1. An extrusion rod 23 is fixedly connected to the side of the movable plate 20 near the mounting shell 15. An extrusion groove 22 is opened on the surface of the mounting shell 15. The middle extrusion groove 22 is vertical, and the two side extrusion grooves 22 are inclined to each other. The surface of the extrusion rod 23 slides against the inner wall of the extrusion groove 22. A threaded rod 21 is rotatably connected inside the grate 1, penetrating the surface of the grate 1. The threaded rod 21 penetrates the surface of the movable plate 20 and is threadedly connected to the inside of the movable plate 20 to drive the movable plate 20 to slide in the grate 1. A baffle plate 2 is provided on the surface of the grate 1. The baffle plate 2 is installed on the grate 1 by screws and can close the end of the threaded rod 21 that protrudes from the surface of the grate 1, thereby preventing the threaded rod 21 from being accidentally touched and protecting the threaded rod 21.

[0036] The grate plate for the anti-clogging grate cooler provided by this utility model is used as follows: When two adjacent grate plates 1 move relative to each other, the rack 11 meshes with the first gear 4, causing the rotating shaft 3 to rotate, which in turn drives the mounting sleeve 12 to rotate. Through the meshing connection of the first bevel gear 13 and the second bevel gear 14, the connecting shaft 17 is driven to rotate, thereby driving the second gear 16 to rotate. Through the meshing of the second gear 16 with the two third gears 18, the two transmission shafts 19 and the conveying rods 8 are driven to rotate. At the same time, since the first bevel gear 13 and the mounting sleeve 12 in the two adjacent mounting shells 15 are arranged oppositely, the two conveying rods 8 on both sides of the grate slot rotate in opposite directions, thereby driving the spiral groove 24 to rotate. The spiral groove 24 conveys pebbles and clinker, allowing the pebbles and clinker to be discharged between the two adjacent fixed blocks 9. Large pebbles and clinker do not come into contact with the inner wall of the spiral groove 24, thus preventing the discharge of large pebbles and clinker and ensuring the effectiveness of the device.

[0037] When the size of the grate opening needs to be adjusted, the operator can remove the baffle plate 2, then rotate the threaded rod 21 to drive the moving plate 20 to slide in the grate plate 1, thereby driving the extrusion rod 23 to move. This causes the extrusion rod 23 to extrude and push against the inner wall of the extrusion groove 22, thereby driving the mounting shell 15 to slide in the grate plate 1. This, in turn, changes the position of the conveying rod 8 and the grate bars 7, thus achieving the adjustment of the grate opening size. This allows the device to adjust the size of the grate opening according to the actual situation.
