Description

Technical Field

[0001] This application relates to the field of grate cooler technology, and more specifically, to an air intake structure for a grate cooler. Background Technology

[0002] A grate cooler is a key piece of equipment used in cement production, mainly for cooling clinker. After the clinker enters the grate cooler from the kiln, it is laid in a layer of a certain thickness on the grate. Cold air is blown in and passes through the moving material layer on the grate in a direction perpendicular to each other, so that the clinker can be rapidly cooled from 1300-1400℃ to below 100℃.

[0003] However, the existing grate coolers have a fixed distance between the cold air spraying components and the grate, which cannot be adjusted according to the size of the clinker volume. This results in reduced cooling efficiency of the clinker and insufficient design practicality. Utility Model Content

[0004] The purpose of this application is to provide an air intake structure for a grate cooler, which adjusts the distance between the spray assembly and the clinker on the grate plate according to the size of the clinker volume, thereby improving the cooling efficiency of the clinker.

[0005] This application provides an air intake structure for a grate cooler, employing the following technical solution:

[0006] An air intake structure for a grate cooler includes a body, a support plate, a jetting assembly, a conveying pipe, and an adjusting assembly. The jetting assembly is disposed on the support plate, one end of the conveying pipe is connected to the jetting assembly, and the other end of the conveying pipe extends out of the body.

[0007] The adjustment assembly includes a motor, a rotating tube, a support tube, a first gear, a second gear, a threaded rod, and a limiting rod. The motor, the rotating tube, and the support tube are all disposed on the inner wall of the machine body. The motor drives the first gear to rotate, and the first gear meshes with the second gear. The second gear is disposed on the rotating tube. The rotating tube is threaded onto the threaded rod. One end of the threaded rod away from the rotating tube is connected to the support plate. One end of the limiting rod is connected to the support plate, and the other end of the limiting rod is slidably installed inside the support tube.

[0008] Preferably, the blowing assembly includes a blowing shroud and a plurality of nozzles, the blowing shroud being disposed on the support plate, the nozzles being disposed on the blowing shroud, and the delivery pipe being used to supply air to the interior of the blowing shroud.

[0009] Preferably, the nozzles are arranged in a matrix.

[0010] Preferably, the nozzle is a conical nozzle.

[0011] Preferably, the delivery pipe is disposed on the support plate.

[0012] Preferably, both the first gear and the second gear are bevel gears.

[0013] Preferably, the adjusting component further includes a limiting block, which is disposed on the limiting rod and located inside the support tube.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] This application, by setting an adjustment mechanism, adjusts the position of the spraying assembly according to the different clinker volumes. When adjustment is needed, the motor is started, and the motor drives the first gear to rotate forward. With the cooperation of the first and second gears, the rotating tube and the threaded rod rotate relative to each other, causing the threaded rod to push the support plate to move away from the rotating tube. The motor then drives the first gear to rotate in reverse, and with the cooperation of the first and second gears, the rotating tube and the threaded rod rotate relative to each other, causing the threaded rod to move the support plate closer to the rotating tube. This achieves the adjustment of the distance between the spraying assembly and the clinker on the grate. Attached Figure Description

[0026] Example

[0027] like Figure 1 and Figure 2 As shown in the embodiment of this application, the air intake structure of the grate cooler includes a body 1, a support plate 2, a jetting assembly 3, a conveying pipe 4, and an adjusting assembly 5. The jetting assembly 3 is mounted on the support plate 2. One end of the conveying pipe 4 is connected to the jetting assembly 3, and the other end of the conveying pipe 4 extends out of the body 1. A blower 16 and a positioning plate 17 are mounted on the outside of the body 1. The blower 16 is connected to the conveying pipe 4, and the positioning plate 17 is mounted on the outer wall of the body 1 to fix the conveying pipe 4. The adjusting assembly 5 includes a motor 6, a rotating pipe 7, a support pipe 8, a first gear 9, a second gear 10, and a threaded rod. 11 and limit rod 12, motor 6, rotating tube 7 and support tube 8 are all set on the inner wall of the machine body 1. Among them, motor 6 and machine body 1 and support tube 8 are fixedly connected, and rotating tube 7 and machine body 1 are rotatably connected. Motor 6 drives the first gear 9 to rotate. The first gear 9 meshes with the second gear 10. The second gear 10 is set on the rotating tube 7. The rotating tube 7 is threaded onto the threaded rod 11. The end of the threaded rod 11 away from the rotating tube 7 is connected to the support plate 2. One end of the limit rod 12 is connected to the support plate 2. The other end of the limit rod 12 is slidably installed inside the support tube 8.

[0028] In use, the blower 16 is started, blowing cold air into the conveying pipe 4. The conveying pipe 4 then sends the cold air into the spray assembly 3, which in turn blows the cold air onto the clinker to cool it. Depending on the size of the clinker, when the position of the spray assembly 3 needs to be adjusted, the motor 6 is started. The motor 6 drives the first gear 9 to rotate forward. With the cooperation of the first gear 9 and the second gear 10, the rotating tube 7 and the threaded rod 11 rotate relative to each other, causing the threaded rod 11 to push the support plate 2 to move away from the rotating tube 7. The motor 6 drives the first gear 9 to rotate in reverse. With the cooperation of the first gear 9 and the second gear 10, the rotating tube 7 and the threaded rod 11 rotate relative to each other, causing the threaded rod 11 to drive the support plate 2 to move closer to the rotating tube 7, thereby adjusting the distance between the spray assembly 3 and the clinker on the grate.

[0029] In this embodiment, the blowing assembly 3 includes a blowing hood 13 and a plurality of nozzles 14. The blowing hood 13 is disposed on the support plate 2, and the nozzles 14 are disposed on the blowing hood 13. The conveying pipe 4 is used to supply air to the interior of the blowing hood 13, and the nozzles 14 blow cold air toward the clinker to achieve cooling of the clinker.

[0030] In this embodiment, the nozzles 14 are arranged in a matrix. The matrix arrangement of the nozzles 14 can increase the spray range of the cold air and improve the cooling effect of the clinker.

[0031] In this embodiment, the nozzle 14 is a conical nozzle 14. The conical nozzle 14 guides the fluid from a larger inlet end to a smaller outlet end. The conical structure can accelerate the fluid and form a specific jet pattern.

[0032] In this embodiment, the conveying pipe 4 is disposed on the support plate 2. The conveying pipe 4 is a flexible pipe, and the part of the conveying pipe 4 located between the support plate 2 and the body 1 is a disc-shaped structure. The disc-shaped conveying pipe 4 can adapt to the deformation requirements when the position of the support plate 2 changes.

[0033] In this embodiment, both the first gear 9 and the second gear 10 are bevel gears.

[0034] In this embodiment, the adjustment component 5 also includes a limiting block 15, which is disposed on the limiting rod 12 and located inside the support tube 8. The limiting block 15 limits the limiting rod 12 to prevent it from detaching from the support tube 8.

[0035] The working principle of the air intake structure of a grate cooler according to an embodiment of this application is as follows:

[0036] Start the blower 16, which blows cold air into the conveying pipe 4. The conveying pipe 4 then sends the cold air into the interior of the blower hood 13. The nozzle 14 blows the cold air onto the clinker to cool it. Depending on the size of the clinker, when the position of the spraying assembly 3 needs to be adjusted, start the motor 6. The motor 6 drives the first gear 9 to rotate forward. With the cooperation of the first gear 9 and the second gear 10, the rotating pipe 7 and the threaded rod 11 rotate relative to each other, causing the threaded rod 11 to push the support plate 2 to move away from the rotating pipe 7. The motor 6 drives the first gear 9 to rotate in reverse. With the cooperation of the first gear 9 and the second gear 10, the rotating pipe 7 and the threaded rod 11 rotate relative to each other, causing the threaded rod 11 to drive the support plate 2 to move closer to the rotating pipe 7, thereby adjusting the distance between the spraying assembly 3 and the clinker on the grate.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
