Technical Field
[0001] The utility model relates to the technical field of grate cooler equipment, and particularly relates to a feeding device for a grate cooler. Background Art
[0002] A grate cooler is an important main equipment in the clinker burning system of a cement plant. Its main functions are to cool and convey cement clinker. During the transportation and cooling of the clinker, grate plates are required. The movement of the grate plates enables the transportation of the clinker. At the same time, the cooling air output by the cooling fan passes through pipelines, grate chambers, and directly contacts the clinker through the grate gaps of the grate plates to reduce the temperature of the clinker, thereby achieving the purpose of cooling and conveying the clinker.
[0003] However, when the existing grate cooler discharges the clinker, most of them directly discharge the clinker into the conveyor through a single feeding pipeline, which will cause the clinker to fall on the conveyor and collide with it, and it is also easy for the conveyed materials falling on the conveyor to splash outside, affecting the transportation of the clinker. Therefore, those skilled in the art provide a feeding device for a grate cooler to solve the problems raised in the above background art. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a feeding device for a grate cooler to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A feeding device for a grate cooler includes: a conical hopper installed at the bottom of the feeding pipe of the grate cooler. A storage cavity is provided inside the conical hopper. Both ends of the top of the conical hopper are provided with L-shaped mounting plates, and one end of the L-shaped mounting plate extends into the storage cavity. An inclined plate is provided at the end of the L-shaped mounting plate located inside the storage cavity. The inclined plate fits against the inner wall of the storage cavity. A buffer plate is rotatably installed inside the L-shaped mounting plate. A shock-absorbing rod is rotatably installed between the end of the buffer plate away from the L-shaped mounting plate and the inclined plate. The shock-absorbing rod includes two sleeves and a sliding rod. Among them, the two sleeves are respectively rotatably installed on the end faces of the inclined plate and the buffer plate. The sliding rod is arranged between the two sleeves. A cavity is provided inside the sleeve. Both ends of the sliding rod penetrate through the sleeve and are slidably installed inside the cavity. An annular limiting plate for limiting its position is provided at the end of the sliding rod located inside the cavity. A buffer spring is provided between the end of the annular limiting plate away from the sliding rod and the inner wall of the cavity.
[0007] Preferably, two symmetrically distributed lugs are provided on the lower end face of the buffer plate. At positions corresponding to the two lugs on the inner side wall of the L-shaped mounting plate, two symmetrically distributed first support plates are provided. One end of the lug away from the buffer plate is inserted between the two L-shaped mounting plates. Moreover, first rotating shafts are provided on the inner walls of the two first support plates, and the other ends of the first rotating shafts are rotatably mounted on the outer walls of the lugs.
[0008] Preferably, two symmetrically distributed second support plates are provided at both ends of the inner side wall of the inclined plate. One sleeve close to the inclined plate is inserted between the two second support plates and rotates inside them.
[0009] Preferably, two symmetrically distributed third support plates are provided at one end of the buffer plate away from the L-shaped mounting plate. One sleeve close to the buffer plate is inserted between the two third support plates and rotates inside them.
[0010] Preferably, second rotating shafts are provided at the mutually remote ends of the outer walls of the two sleeves. The two sleeves are respectively rotatably mounted between the two second support plates and the two third support plates through the second rotating shafts.
[0011] Preferably, through holes communicating with the cavity are provided at the mutually close ends of the two sleeves. The sliding rod is inserted into the cavity through the through hole and slides inside it, and the end face area of the annular limiting plate is larger than the opening area of the through hole.
[0012] Preferably, a plurality of fixing bolts are evenly provided on the top of the L-shaped mounting plate. The fixing bolts penetrate through the L-shaped mounting plate and are threadedly mounted on the top of the conical hopper.
[0013] Compared with the prior art, the advantages of the present utility model are as follows:
[0014] By providing the conical hopper, when discharging the clinker in the grate cooler, the clinker can fall from the discharge pipe of the grate cooler into the storage cavity in the conical hopper. The buffer plate contacts the clinker. The buffer plate after being collided rotates inside the L-shaped mounting plate and presses the shock-absorbing rod. Then, the two buffer springs inside the shock-absorbing rod buffer the collision force of the clinker received by the buffer plate, preventing the clinker from splashing on the buffer plate. Then, the clinker falling on the two buffer plates slides downward along their end faces and falls from the empty slots between the two buffer plates. The clinker falls from the discharge port of the conical hopper onto the conveyor for transportation, thus completing the discharging work of the clinker. The buffer plate can bear the clinker, preventing the clinker from directly falling onto the conveyor. This not only avoids the damage of the conveyor caused by the direct collision of the clinker falling onto it, but also avoids the trouble of the clinker splashing outside the conveyor when directly falling onto it, improving the conveying efficiency and effect of the clinker.

[0023] Combined with Figures 1-6As shown in the figure, a charging device for a grate cooler includes: a conical hopper 1 installed at the bottom of the charging pipe of the grate cooler. A storage cavity 101 is provided inside the conical hopper 1. L-shaped mounting plates 11 are arranged at both ends of the top of the conical hopper 1. Moreover, one end of the L-shaped mounting plate 11 extends into the storage cavity 101. An inclined plate 12 is arranged at the end of the L-shaped mounting plate 11 inside the storage cavity 101. The inclined plate 12 is attached to the inner wall of the storage cavity 101. And a buffer plate 13 is rotatably installed inside the L-shaped mounting plate 11. A shock-absorbing rod 2 is rotatably installed between the end of the buffer plate 13 away from the L-shaped mounting plate 11 and the inclined plate 12. The shock-absorbing rod 2 includes two sleeves 21 and a sliding rod 22. Among them, the two sleeves 21 are respectively rotatably installed on the end faces of the inclined plate 12 and the buffer plate 13. The sliding rod 22 is arranged between the two sleeves 21. And a cavity 211 is provided inside the sleeve 21. Both ends of the sliding rod 22 penetrate through the sleeve 21 and are slidably installed inside the cavity 211. And an annular limiting plate 221 for limiting its position is arranged at the end of the sliding rod 22 inside the cavity 211. A buffer spring 23 is arranged between the end of the annular limiting plate 221 away from the sliding rod 22 and the inner wall of the cavity 211.
[0024] In one embodiment, when the buffer plate 13 is installed in the conical hopper 1 for use, the inclined plate 12 can be first inserted into the conical hopper 1, so that the inclined plate 12 is attached to the inner wall of the storage cavity 101, and the L-shaped mounting plate 11 is clamped on the top of the conical hopper 1. Then, the fixing bolt 14 is screwed and installed on the top of the conical hopper 1 to complete the installation of the L-shaped mounting plate 11. It can make the buffer plate 13 rotatably installed inside the L-shaped mounting plate 11 tilt in the storage cavity 101 under the thrust of the shock-absorbing rod 2 to hold up the clinker, preventing the clinker from directly falling into the conical hopper 1 and colliding with it, thus realizing the protection of the conical hopper 1.
[0025] In one embodiment, when the clinker in the grate cooler falls into the conical hopper 1, the buffer plate 13 can contact the clinker. And the buffer plate 13 after being collided rotates inside the L-shaped mounting plate 11 and presses the shock-absorbing rod 2. Then, the two buffer springs 23 inside the shock-absorbing rod 2 buffer the collision force of the clinker received by the buffer plate 13 to prevent the clinker from splashing on the buffer plate 13. Then, the clinker falling on the two buffer plates 13 slides downward along their end faces and falls from the empty slot between the two buffer plates 13, and the clinker falls from the discharge port of the conical hopper 1 onto the conveyor for transportation. In this way, the discharging work of the clinker is completed. The buffer plate 13 can bear the clinker to prevent the clinker from directly falling onto the conveyor, not only avoiding the damage caused by the direct collision of the clinker with the conveyor when it falls onto the conveyor, but also avoiding the trouble of the clinker splashing outside the conveyor when it directly falls onto the conveyor, improving the conveying efficiency and effect of the clinker.
[0026] In one embodiment, when the buffer plate 13 is collided by the clinker, the collided buffer plate 13 can be inclined downward inside the L-shaped mounting plate 11 in cooperation with the first support plate 111 and the first rotating shaft 112 through the lugs 131 mounted thereon, so that the flipping buffer plate 13 will not interfere with the L-shaped mounting plate 11. Then, the inclined buffer plate 13 presses the shock-absorbing rod 2, and the two sleeves 21 slide on the outer wall of the sliding rod 22 through the through holes 212 and squeeze the buffer spring 23, thereby achieving the effect of buffering the collision force received by the buffer plate 13. Moreover, since the two sleeves 21 are respectively rotatably mounted between the two second support plates 121 and the two third support plates 132 through the second rotating shafts 213, the two ends of the shock-absorbing rod 2 can rotate on the end faces of the inclined plate 12 and the buffer plate 13 respectively, and the shock-absorbing rod 2 will not interfere with the displacement of the buffer plate 13, ensuring the use of the buffer plate 13.
[0027] In one embodiment, since the end face area of the annular limiting plate 221 is larger than the opening area of the through hole 212, when the buffer plate 13 is not in use, the annular limiting plate 221 can limit the two sleeves 21 on the outer wall of the sliding rod 22 to prevent the sleeves 21 from disengaging from the sliding rod 22 under the elastic force of the buffer spring 23, avoiding the situation that the sleeves 21 cannot buffer the buffer plate 13 due to disengaging from the sliding rod 22, and ensuring the use effect of the buffer plate 13.
[0028] The working principle of the present utility model is as follows: when discharging the clinker in the grate cooler, the clinker can fall from the discharging pipe of the grate cooler into the storage cavity 101 in the conical hopper 1, contact with the buffer plate 13, and the collided buffer plate 13 rotates inside the L-shaped mounting plate 11 and presses the shock-absorbing rod 2. Then, the two buffer springs 23 inside the shock-absorbing rod 2 buffer the collision force of the clinker received by the buffer plate 13 to prevent the clinker from splashing on the buffer plate 13. Then, the clinker falling on the two buffer plates 13 slides downward along their end faces and falls from the empty slot between the two buffer plates 13, and the clinker falls from the discharging port of the conical hopper 1 onto the conveyor for transportation, thus completing the discharging work of the clinker. The buffer plate 13 can bear the clinker to prevent the clinker from directly falling onto the conveyor, not only avoiding the damage of the conveyor caused by the direct collision of the clinker falling onto it, but also avoiding the trouble of the clinker splashing outside the conveyor when directly falling onto it, improving the conveying efficiency and effect of the clinker.
[0029] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
