Description

Technical Field

[0001] The utility model relates to the field of sludge drying equipment, in particular to sludge drying equipment with convenient feeding. Background Art

[0002] The sludge dryer is an indirect heating low-speed stirring dryer. There are usually two or four hollow rotating shafts inside the equipment. Fan-shaped wedge-shaped hollow blades are densely arranged in parallel on the hollow shafts. The structural design is particularly ingenious.

[0003] The feed port of the existing horizontal sludge dryer is generally located at one end of the dryer. After the sludge is put into the dryer from the feed port, the rotation of the dryer roller uses the blades on the inner wall of the roller to push the sludge along the axial direction of the roller, gradually making the sludge evenly spread into the roller, and then the hot air drying work begins.

[0004] With regard to the above-mentioned related technologies, the existing sludge generally undergoes a dehydration process before drying to reduce the water content in the sludge to reduce drying energy consumption. The dehydrated sludge has poor fluidity and a certain viscosity. The rotation of the blades on the inner wall of the drum makes it difficult to efficiently and quickly distribute the sludge evenly along the axial direction of the drum, affecting the efficiency of sludge drying. Therefore, the existing horizontal sludge drying equipment has the problem that the sludge is not easy to quickly and evenly enter the drum. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a sludge drying device with convenient feeding, so as to solve the technical problem that the sludge of the existing horizontal sludge drying device is not convenient to enter the drum quickly and evenly.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sludge drying equipment with convenient feeding, comprising a bracket, one end of the bracket is connected to a fixed end cover, and the other end is connected to a movable end cover, a rotating drum is rotatably connected between the movable end cover and the fixed end cover, a plurality of feeding ports are arranged at intervals along the length direction of the side wall of the rotating drum, a sealing step is arranged at a position close to the inside of the rotating drum, a sealing plate with the same curvature as the rotating drum is connected to the feeding port, the sealing step is used to limit the movement of the sealing plate toward the inside of the rotating drum, and the sealing plate is connected to the feeding port by multiple sets of bolts.

[0007] By adopting the above technical solution, a plurality of feeding ports for adding sludge are arranged at intervals along the length direction on the wall of the drum. When it is necessary to add sludge to be dried into the drum, it is only necessary to open the sealing cover at the feeding port to evenly and efficiently add sludge to various places in the drum, so that the sludge can be quickly and evenly distributed in the drum along the length direction.

[0008] The utility model is further configured such that one end of the bracket close to the fixed end cover is lower than the other end close to the movable end cover, and the inner wall of the rotating drum is connected with a spiral stirring blade.

[0009] By adopting the above technical solution, the drum is tilted. After the sludge is added into the drum, it is pushed by the stirring blades on the inner wall of the rotating drum to move toward the movable end cover, but slides downward due to its own gravity, resulting in the effect of tumbling the sludge in the drum, thereby effectively improving the sludge drying efficiency.

[0010] The utility model is further configured that a baffle with a conical structure is connected to one end of the rotating drum close to the fixed end cover, the baffle is arranged along the length direction of the rotating drum toward one end of the movable end cover, and a through opening is arranged in the middle.

[0011] By adopting the above technical solution, the baffle can effectively prevent the sludge from sliding into the fixed end cover due to its own gravity and being unable to be discharged, and the opening provided in the middle of the baffle can allow hot air to pass through, thereby performing hot air drying on the sludge in the drum.

[0012] The utility model is further configured such that a driving motor is fixedly arranged on one side of the bracket, a ring gear is fixedly connected to the outer wall of the rotating drum at a position close to the driving motor, and a toothed belt is connected between the output end of the driving motor and the ring gear.

[0013] By adopting the above technical solution, the power of the driving motor is used to transmit the power through the toothed belt, so that the drum can rotate on the roller frame with its own axis as the axis, so as to achieve the purpose of mixing the sludge in the drum.

[0014] The utility model is further configured that a slide rail is arranged at one end of the bracket close to the movable end cover, and sliding brackets are fixedly connected to both sides of the movable end cover, and the sliding brackets are slidably connected in the slide rails.

[0015] By adopting the above technical solution, after the sludge in the drum is dried, when the sludge in the drum needs to be discharged, the movable end cover needs to be slid in a direction away from the drum to provide a sufficient discharge port for discharging the sludge in the drum.

[0016] The utility model is further configured that the slide rail is provided with a latch at one end facing the rotating drum, and the bottom end of the sliding bracket is provided with a hole for matching the latch.

[0017] By adopting the above technical solution, the pin set at the end of the slide rail can effectively limit the sliding of the sliding bracket. After the movable end cover and the rotating drum are rotated and connected, the pin plays a role in limiting the movement of the sliding bracket, thereby enabling the movable end cover to be stably connected to the rotating drum.

[0018] The utility model is further configured that the bottom end of the bracket is provided with roller frames for supporting the rotating drum on both sides of the rotating drum.

[0019] By adopting the above technical solution, the roller frame is used to support the rotating drum, and while supporting the rotating drum, the rotating drum can also be kept rotating under the drive of the driving structure.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. The utility model arranges a plurality of feeding ports for adding sludge at intervals along the length direction on the drum wall. When the sludge to be dried needs to be added to the drum, it is only necessary to open the sealing cover at the feeding port to evenly add the sludge to various places in the drum, so that the sludge is quickly and evenly distributed in the drum along the length direction.

[0022] 2. The utility model uses a support structure to support the inclined rotating drum, and a conical baffle is arranged at the bottom of the rotating drum. Under the premise of not affecting the flow of hot air, the sludge in the rotating drum can be turned over better during the drying process, which is conducive to the rapid drying of the sludge.

[0023] 3. The utility model provides a slide rail structure at the higher end of the bracket, and slides the end cover structure at one end of the drum. When the dried sludge in the drum needs to be discharged, it is only necessary to release the limiting structure of the end cover and then move the end cover, which effectively improves the speed of discharging the dried sludge from the drum and is also convenient for the sludge collection vehicle to receive the sludge at the position where the sludge is discharged below the bracket.

[0034] See also Figure 1-3 The slide rail 10 is provided with a latch 12 at one end facing the drum 4, and the bottom end of the sliding bracket 11 is provided with a hole for matching the latch 12. The latch 12 arranged at the end of the slide rail 10 can well limit the sliding of the sliding bracket 11. After the movable end cover 3 and the drum 4 are rotated and connected, the latch 12 plays a role in limiting the movement of the sliding bracket 11, so that the movable end cover 3 can be stably connected to the drum 4. The bottom end of the bracket 1 is provided with roller frames 6 for supporting the drum 4 on both sides of the drum 4. The roller frames 6 are used to support the drum 4, and while supporting the drum 4, the drum 4 can also be driven by the driving structure to keep rotating.

[0035] See also Figure 1-4A driving motor 7 is fixedly arranged on one side of the bracket 1, and a ring gear 8 is fixedly connected to the outer wall of the drum 4 at a position close to the driving motor 7. A toothed belt 9 is connected between the output end of the driving motor 7 and the ring gear 8. The power of the driving motor 7 is transmitted through the toothed belt 9, so that the drum 4 rotates on the roller frame 6 with its own axis as the axis to achieve the purpose of mixing the sludge in the drum. A slide rail 10 is arranged on one end of the bracket 1 close to the movable end cover 3, and sliding brackets 11 are fixedly connected to the two sides of the movable end cover 3. The sliding bracket 11 is slidably connected to the slide rail 10. After the sludge in the drum 4 is dried, when the sludge in the drum 4 needs to be discharged, the movable end cover 3 needs to be slid in the direction away from the drum 4 to provide a sufficient discharge port for the discharge of the sludge in the drum 4. The transfer vehicle or the transmission belt for receiving the dried sludge can extend to the bottom of the highest point of the drum 4.

After the sludge is added into the drum 4, it is pushed by the stirring blade 16 on the inner wall of the rotating drum 4 to move toward the movable end cover 3, but slides downward due to its own gravity, resulting in the effect of tumbling the sludge in the drum 4, thereby effectively improving the sludge drying efficiency. A baffle 15 with a conical structure is connected to the end of the drum 4 close to the fixed end cover 2. The baffle 15 is arranged along the length direction of the drum 4 toward one end of the movable end cover 3, and a through opening is arranged in the middle. The baffle 15 can effectively prevent the sludge from sliding into the fixed end cover 2 due to its own gravity and being unable to be discharged, and the through opening arranged in the middle of the baffle 15 can allow hot air to pass through, thereby performing hot air drying on the sludge in the drum 4.

[0038] The working principle of the utility model is as follows: after unscrewing the bolts connecting the sealing plate 13 and the feeding port 5, the sealing plate 13 can be removed to conveniently add sludge into the drum 4 through the feeding port 5; after the sludge is added, the sealing plate 13 is closed, the driving motor 7 is started, and the hot air duct is connected to the vents of the fixed end cover 2 and the movable end cover 3; the sludge inside the drum 4 is turned over in the drum 4, and the hot air flow efficiently dries the sludge in the drum 4; after the sludge in the drum 4 is dried, the locking of the sliding bracket 11 by the latch 12 is released, and then the movable end cover 3 is pushed in the direction away from the drum 4; at this time, the drum 4 rotates, and the dried sludge in the drum 4 is discharged and falls from one end of the drum 4 close to the movable end cover 3, thereby completing the drying of the sludge.
