DETAILED DESCRIPTION
[0017] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.
[0018] See Figure 1-2As shown, the utility model is an ash conveying elbow that is easy to clear blockage, comprising an ash conveying elbow body 1, an inclined inspection channel 3 is provided at the lower outer side of the ash conveying elbow body 1, an inspection blind plate 4 is provided on the inspection channel 3, an inspection hole 10 is opened on the inspection blind plate 4, and a cleaning tool for cleaning dust is provided on the inspection hole 10, and the cleaning tool comprises a wire rope 5, a cleaning head 7 and a rotating handle 6. One end of the wire rope 5 is connected to the cleaning head 7 after passing through the inspection hole 10, and the other end of the wire rope 5 is connected to the rotating handle 6. A storage device 2 for storing the cleaning tool is provided on the ash conveying elbow body 1 above the inspection channel 3. When the ash conveying elbow body 1 is blocked by dust accumulation, the wire rope 5 is released from the storage device 2, and the wire rope 5 is extended inward by rotating the rotating handle 6. The operator then pokes it in with force, rotating the wire rope 5 while poking, so that the conical knife 8 on the cleaning head 7 can better clean the harder scaling. After the cleaning is completed, the wire rope 5 can be swung so that the brush 9 on the cleaning head 7 can clean the dust remaining on the ash conveying elbow, and the cleaning effect is better. After the cleaning is completed, the cleaning head 7 is pulled back into the inspection channel 3 for storage. The wire rope 5 is wound around the bottom rod 23, and the pressure rod 22 is rotated to tighten the wire rope 5. The pressure rod 22 is fixed by the locking bolt so that the wire rope 5 can be stored in the storage device 2, avoiding clutter on site and making the overall appearance more beautiful. This ash conveying elbow is integrated with a cleaning tool and has a cleaning function. It can quickly clean the blocked dust and effectively ensure the continuity of production.
[0019] Specifically, the storage device 2 includes a bottom rod 23, a column 24, a pressure rod 22 and a connecting rod 21. One end of the bottom rod 23 is connected to the ash conveying elbow body 1, and the other end is connected to the column 24. One end of the pressure rod 22 is rotatably connected to the column 24, and the other end is connected to the connecting rod 21. The connecting rod 21 is connected to the bottom rod 23 by a bolt. The wire rope 5 is arranged between the pressure rod 22 and the bottom rod 23 after being wound. The pressure rod 22 presses the wire rope 5 so that the wire rope 5 will not loosen after being wound, saving placement space and storing the wire rope 5.
[0020] Preferably, a plurality of conical knives 8 are provided at the front end of the cleaning head 7, and the conical knives 8 are arranged in a circular manner. The circular arrangement of the conical knives 8 allows for better peeling of harder scale during rotation, thereby improving the cleaning effect.
[0021] Furthermore, a brush 9 is provided on the outer surface of the cleaning head 7. The brush 9 on the cleaning head 7 can clean the dust remaining on the ash conveying elbow, and the cleaning effect is better.
[0022] Furthermore, a silicone sleeve 11 is provided between the steel wire rope 5 and the inspection hole 10. Since the silicone sleeve 11 is soft, it can perform a sealing function while not hindering the stirring of the steel wire rope 5.
[0023] Furthermore, the inspection channel 3 is tilted downward, and the angle between the inspection channel 3 and the ash conveying elbow body 1 is 30° to 45°, so that the wire rope 5 can better penetrate into the ash conveying elbow body 1 to clean its blocked position.
[0024] The cleaning brush 7 of this embodiment can be used to clean the dust in the dust collecting box 2, and the dust collecting box 2 can be cleaned by the cleaning brush 7. The utility model discloses an ash conveying elbow pipe which is easy to clear blockage, has the advantages of simple and effective operation, short processing time, no influence on production, and is suitable for areas with high explosion-proof requirements.
