Description

Technical Field

[0001] The utility model relates to the technical field of sludge processing, in particular to a paddle-type sludge dryer. Background Art

[0002] In recent years, a large number of urban sewage treatment plants have been built to maintain the urban water environment and prevent urban water pollution, which has gradually alleviated the problem of urban sewage pollution. However, how to deal with the sludge in urban sewage treatment is a problem that we are facing now. If it is not handled properly, it will cause serious secondary pollution. Therefore, it is necessary to dry the sludge.

[0003] However, when the existing paddle-type sludge dryer is put into use, the staff needs to add the sludge to be dried into the working shell through the feeding port, and then the sludge is crushed by the paddle rotating rod. However, since the sludge is relatively wet and sticky, the sludge is in a block shape. The paddle rotating rod cannot crush the sludge in the first time during processing, which easily leads to sludge blockage at the feeding port, slowing down the working speed of the dryer.

[0004] At the same time, most of the paddle-type sludge dryers collect the dried sludge manually. The staff needs to tilt the collection tube to the surface of the discharge port, and then straighten the collection tube for collection. It is easy for the collection tube to collide with the discharge port, causing damage to the discharge port. In addition, more dry sludge is collected at one time, and it is inconvenient for the staff to replace the collection tube, which increases the workload of the staff. Utility Model Content

Under the action of the discharging port 4, the dried sludge can be discharged, enabling the staff to collect it. On one side of the working shell 2, there is a bolted stepping motor 5. The stepping motor 5 can drive the drying component 16 to rotate inside the working shell 2. On one side of the working shell 2, there is a reciprocating mechanism 6. Inside the working shell 2, there is a sliding connection with a scraper 7. With the cooperation of the stepping motor 5 and the reciprocating mechanism 6, the scraper 7 can reciprocate inside the working shell 2, capable of moving the material entering from the feeding port 3, effectively reducing the blockage of the material added from the feeding port 3, accelerating the working rate of the dryer, thereby increasing the practicality of the dryer. One end of the scraper 7 is bolted with a guide block 8. Inside the guide block 8, there is a sliding connection with a guide rod 9. Both sides of the guide rod 9 are bolted to the inside of the working shell 2. Under the action of the reciprocating mechanism 6, the scraper 7 can drive the guide block 8 to move on the surface of the guide rod 9, effectively preventing the scraper 7 from shifting in position during operation, increasing the stability of the scraper 7, and thus increasing the stability of the dryer. On one side of the support frame 1, there is a hydraulic rod 10. The output shaft of the hydraulic rod 10 is bolted with a connection shell 11. Under the action of the hydraulic rod 10, the connection shell 11 can move up and down at the bottom of the support frame 1. The number of hydraulic rods 10 is four and they are symmetrically designed with the central axis of the connection shell 11, effectively preventing the connection shell 11 from shifting in position during operation, increasing the stability of the connection shell 11. On one side of the connection shell 11, there is a moving mechanism 12. On the top of the connection shell 11, there is a sliding connection with a connecting plate 13. Under the action of the moving mechanism 12, the connecting plate 13 can move on the top of the connection shell 11. On the top of the connecting plate 13, there is a bolted limit shell 14. Inside the limit shell 14, there is a movable connection with a collecting cylinder 15. The collecting cylinder 15 can collect the dried sludge, facilitating the staff to collect it, reducing the labor intensity of the staff, and under the action of the limit shell 14, effectively preventing the collecting cylinder 15 from tilting when moving with the connecting plate 13, increasing the stability of the collecting cylinder 15. At the same time, with the cooperation of the number of collecting cylinders 15, it is convenient for the staff to collect the dried sludge, reducing the labor intensity of the staff, thereby increasing the practicality of the dryer.

[0023] The reciprocating mechanism 6 includes a rotating rod 61. The surface of the rotating rod 61 is rotatably connected to one side of the working shell 2.

The other side of the rotating rod 61 is fixed with a reciprocating threaded rod 62. The other end of the reciprocating threaded rod 62 is rotatably connected to the inner cavity of the working shell 2. A sleeve 63 is threadedly connected to the surface of the reciprocating threaded rod 62. One side of the sleeve 63 is bolted to one side of the scraper 7. The central axis of the rotating rod 61 and the central axis of the reciprocating threaded rod 62 are on the same straight line. Under the action of the stepping motor 5, the rotating rod 61 can drive the sleeve 63 to move through the reciprocating threaded rod 62, and the sleeve 63 drives the scraper 7 to reciprocate in the inner cavity of the working shell 2, effectively preventing the materials added at the feeding port 3 from accumulating, thereby increasing the working rate of this dryer.

[0024] The moving mechanism 12 includes a servo motor 121. One side of the servo motor 121 is bolted to one side of the connecting shell 11. The output shaft of the servo motor 121 is fixed with a lead screw 122. The other end of the lead screw 122 is rotatably connected to the inner cavity of the connecting shell 11. A moving block 123 is threadedly connected to the surface of the lead screw 122. The top of the moving block 123 is bolted to the bottom of the connecting plate 13. With the cooperation of the servo motor 121 and the lead screw 122, the moving block 123 can drive the collection barrel 15 to move through the connecting plate 13, and with the cooperation of the hydraulic rod 10, the collection barrel 15 without added materials can be moved to the bottom of the discharge port 4, and then the discharge port 4 can be moved into the interior of the collection barrel 15, facilitating the staff to collect the dried sludge and reducing the labor intensity of the staff.

[0025] Working principle: First, the staff adds the sludge to be dried into the interior of the working shell 2 through the feeding port 3. Subsequently, under the action of the stepping motor 5, the drying component 16 can crush the sludge. At the same time, the stepping motor 5 drives the rotating rod 61 to rotate through two belt pulleys and a timing belt. The rotating rod 61 drives the sleeve 63 to drive the scraper 7 to move reciprocally through the reciprocating threaded rod 62, enabling the materials at the bottom of the feeding port 3 to be distributed on the top of the drying component 16, reducing the accumulation of sludge at the position of the feeding port 3. At the same time, the scraper 7 drives the guiding block 8 to move reciprocally on the surface of the guiding rod 9, making the movement of the scraper 7 more stable. When the dried sludge is discharged into the interior of the collection cylinder 15 through the discharge port 4 and the collection in the collection cylinder 15 is completed, under the action of the hydraulic rod 10, the inner wall of the collection cylinder 15 is separated from the surface of the discharge port 4. And under the cooperation of the servo motor 121 and the lead screw 122, the moving block 123 can drive the collection cylinder 15 to move through the connecting plate 13, enabling the collection cylinder 15 without added materials to move to the bottom of the discharge port 4. Subsequently, the hydraulic rod 10 drives the collection cylinder 15 to move upward, making the inner wall of the collection cylinder 15 correspond to the surface of the discharge port 4. Then the staff can take out the collection cylinder 15 filled with sludge through the handle.
