Description

Technical Field

[0001] The utility model relates to the technical field of three-way baffles, in particular to a novel three-way baffle for a bucket elevator. Background Art

[0002] Bucket elevator is a continuous conveying machine used to lift materials in a vertical or nearly vertical direction. It is mainly composed of a hopper, storage box, drive device, top and bottom rollers, guide chain, tensioning device and casing. The hopper scoops up the material from the storage box below and lifts it to the top with the conveyor belt or chain. When the material reaches the top, it bypasses the top wheel and flips downward to pour the material into the receiving trough. The empty hopper continues to move downward to the bottom and enters the next cycle.

[0003] Bucket elevators can adjust the conveying speed according to the conveying volume and select the appropriate lifting height. It is suitable for lifting from low to high places, and is often used in industrial places such as storage warehouses, cement plants, stone factories, mines, etc. that need to convey materials vertically, especially for conveying powder, granular and bulk materials. In order to ensure the continuity of production, bucket elevators are often set up with two groups, that is, one for use and one for backup. When the bucket elevator in use has problems or needs maintenance, it is necessary to switch to the backup bucket elevator. When switching to the backup bucket elevator, a three-way baffle is required.

[0004] The interior of the three-way baffle is provided with a guide plate, through which the falling direction of the material can be changed so that the material falls from one bucket elevator to another. When the existing three-way baffle is in use, the boiler slag falls and passes through the guide plate in the three-way baffle. The slag impacts the guide plate for a long time, which will cause sand holes to appear on the surface of the guide plate. The slag can enter the hopper and storage box of the standby bucket elevator through the sand holes on the guide plate. When the standby bucket elevator is not used for a long time, the slag in the standby bucket elevator will become compacted, making it difficult to start the bucket elevator. Therefore, it is necessary to start the slag removal regularly, which is inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0021] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figure 1-7As shown, a novel three-way baffle for bucket elevator comprises a material guide box 1, wherein an inlet 2 is arranged at the upper end of the material guide box 1, and two outlets 3 are arranged at the lower end of the material guide box 1. An adjusting mechanism for changing the falling direction of materials is arranged inside the material guide box 1, and the adjusting mechanism comprises an internal hollow shell 4, and air holes 5 are evenly opened on the outer surfaces of both sides of the shell 4. A partition 6 for closing the air holes 5 on the outer surface of one side of the shell 4 is arranged inside the shell 4, and a guide rod 7 is arranged inside the shell 4, and the partition 6 is slidably connected to the guide rod 7. A fixed shaft 8 is arranged at one end of the outer surface of the material guide box 1, and the fixed shaft 8 is rotatably connected to the material guide box 1, and further comprises a fixing mechanism for fixing the fixed shaft 8. The fixed axis 8 is a power unit for rotating, and the power unit includes an electric telescopic device 9. The outer surface of the material guide box 1 is provided with a first clamping plate 10 and a second clamping plate 11. The electric telescopic device 9 is located between the first clamping plate 10 and the second clamping plate 11 and is rotatably connected with the first clamping plate 10 and the second clamping plate 11. A fixed plate 12 is provided on the fixed axis 8, and a card slot 13 is provided on the fixed plate 12. The output end of the electric telescopic device 9 is rotatably connected with the card slot 13. An air intake pipe 14 is provided at the other end of the outer surface of the material guide box 1. The air intake pipe 14 is connected with the shell 4. A gate valve 15 is provided at one end of the air intake pipe 14, and it also includes a branch pipe 16 connected with the gate valve 15.

[0023] When the device is in use, it is necessary to convey air into the branch pipe 16. Since the boiler needs to be supplied with air by the fan when in use, it is only necessary to separate a portion of the air sent to the boiler by the fan and feed it into the branch pipe 16. The air in the branch pipe 16 is conveyed to the interior of the shell 4 through the gate valve 15 and the air inlet pipe 14, and then discharged to the outside of the shell 4 through the air hole 5 on the shell 4. The amount of air conveyed into the shell 4 can be controlled by the gate valve 15. When the gate valve 15 is opened widely, the amount of air entering the shell 4 is large, and when the gate valve 15 is opened slightly, the amount of air entering the shell 4 is small.

[0024] After the boiler ash enters the interior of the guide box 1 through the inlet 2 of the guide box 1, it is necessary to control the direction of the ash so that the ash can enter the storage box through the corresponding outlet 3. Specifically, Figure 1As shown, by controlling the output end of the electric telescopic device 9 to extend or retract, the card slot 13 and the fixed plate 12 can be driven to swing, and the fixed shaft 8 can be driven to rotate by the swing of the fixed plate 12. After the fixed shaft 8 rotates, the shell 4 inside the guide box 1 can be driven to rotate. After the shell 4 rotates to the specified position, it can cover one of the ash channels, so that all the ash is discharged outward through the other discharge port 3. The adjustment of the position of the shell 4 needs to be completed before the ash falls. When the shell 4 is adjusted, the shell 4 is in an inclined state. Under the action of gravity, the shell The partition plate 6 inside the housing 4 will slide along the guide rod 7 to the relatively lower side of the housing 4 and cover the air holes 5 on the housing 4 on that side. When the wind transported by the fan is transported to the housing 4 through the branch pipe 16, the gate valve 15 and the air inlet pipe 14, the wind in the housing 4 will be ejected to the outside from the air holes 5 not covered by the partition plate 6 due to the restriction of the partition plate 6. When the ash falls from top to bottom, the high-speed gas ejected through the air holes 5 enables most of the ash to change its moving trajectory without contacting the housing 4, thereby reducing the wear on the housing 4 and facilitating the protection of the housing 4.

[0025] The inner diameter of the air hole 5 should not be too large to ensure that the gas in the shell 4 has sufficient strength to change the falling trajectory of the ash when it is ejected outward through the air hole 5.

[0026] The fixing plate 12 and the housing 4 are placed in the same position, so the position of the housing 4 can be quickly determined by observing the position of the fixing plate 12 .

[0027] Furthermore, both ends of the shell 4 are arranged to be arc-shaped, and a first sealing portion 17 matching the arc shape of one end of the shell 4 is arranged inside the shell 4 and between the two discharge ports 3, and second sealing portions 18 matching the arc shape of the other end of the shell 4 are arranged on both sides of the inside of the feed port 2. Both the first sealing portion 17 and the second sealing portion 18 are arc-shaped to improve the sealing with the shell 4.

[0028] Furthermore, limit blocks 19 are provided on the inner sides of the first sealing portion 17 and the second sealing portion 18. After the position of the shell 4 is adjusted, when the upper surface of the shell 4 is impacted by ash, the shell 4 can be supported by the limit blocks 19, which is beneficial to maintaining the stability of the shell 4 in the material guide box 1.

[0029] Furthermore, a one-way valve 20 is provided inside the air hole 5, and the one-way valve 20 is made of silicone. The wind in the shell 4 is blown out to the outside of the shell 4 through the one-way valve 20. When there is no wind in the shell 4, smaller ash from the outside will not be able to enter the shell 4 through the air hole 5, ensuring that the partition 6 in the shell 4 can be used normally.

[0030] Furthermore, a sliding hole is opened on the partition 6, and a fixing ring 21 is installed inside the sliding hole. The thickness of the fixing ring 21 is less than the thickness of the partition 6. The guide rod 7 is slidably connected with the fixing ring 21. The fixing ring 21 is made of a low-friction plastic material, which can be nylon material. The fixing ring 21 can reduce the friction between the guide rod 7 and the fixing ring 21. When the shell 4 is adjusted, the partition 6 can be quickly adjusted in position.

[0031] The device can change the moving trajectory of the falling ash by conveying air into the shell 4 and spraying it to the outside of the shell 4 through the air holes 5, so that most of the ash can be discharged from the designated discharge port 3 without contacting the shell 4, thereby reducing the wear of the shell 4 by the ash, effectively protecting the shell 4, greatly reducing the ash compaction in the spare bucket elevator, and greatly extending the interval time for regular start-up of the bucket elevator to remove slag, which is easy to use.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
