Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a sludge removal device for sewage treatment. Background Art

[0002] With the rapid development of industrialization and urbanization, the sewage discharge is increasing day by day, and sewage treatment has become a global environmental problem. In common sewage treatment, it is necessary to carry out sludge removal treatment on sewage to filter out the sediment in the sewage for subsequent treatment. During the sewage treatment process of traditional sludge removal devices, the sediment in the sewage is filtered out through a filter screen. After long-term filtration, a large amount of sediment will accumulate on the filter frame, which is not convenient to clean. This requires operators to frequently replace the filter frame to ensure the sewage filtration quality, resulting in a low sewage filtration efficiency. Summary of the Utility Model

[0003] In view of this, the utility model provides a sludge removal device for sewage treatment, in which the filter frame will be automatically replaced after filtering sewage, and the sediment on the filter frame can be better dumped, so as to improve the sewage sludge removal efficiency.

[0004] The technical solution of the utility model is: a sludge removal device for sewage treatment, including a base, an outer shell is placed on the base, a feeding frame is fixedly connected inside the outer shell, a discharging frame is fixedly connected inside the outer shell, the discharging frame is located below the feeding frame, a filtering mechanism and a flapping mechanism are arranged inside the outer shell, the filtering mechanism is used for filtering sediment, and the flapping mechanism is used for removing the sediment on the filtering mechanism, so that the filtering mechanism can better filter sediment and improve the filtering efficiency.

[0005] In one embodiment, the filtering mechanism includes a bracket, the bracket is fixedly connected to the bottom inside the outer shell, a rotating shaft is rotatably connected to the bracket, an overrunning clutch is fixedly connected to the bottom of the rotating shaft, and a column gear is fixedly connected to the overrunning clutch.

[0006] In one embodiment, the filtering mechanism further includes a rotating block, two rotating blocks are rotatably connected to the rotating shaft, the two rotating blocks are symmetrically arranged, rotating gears are fixedly connected to both the two rotating blocks, a toothed rod is fixedly connected to the bracket, the toothed rod meshes with one of the rotating gears, torsion springs I are connected between both the two rotating gears and the rotating shaft, filter frames are fixedly connected to both the two rotating blocks, the filter frame and the rotating gear on the same side are in a group, and one of the filter frames is located between the feeding frame and the discharging frame.

[0007] In one embodiment, the filtering mechanism further includes a motor, the motor is fixedly connected to the bottom inside the outer shell, a transmission gear is fixedly connected to the output shaft of the motor, and the transmission gear meshes with the column gear.

[0008] In one embodiment, the flapping mechanism includes a turntable fixedly connected to the transmission gear. A flapping rod is rotatably connected to the bracket, and a second torsion spring is connected between the flapping rod and the bracket.

[0009] The beneficial effects of the present utility model are as follows: 1. The filter frame between the feeding frame and the discharging frame is far below the feeding frame. Subsequently, the rotating gear in the same group as this filter frame meshes with the rack, causing the rotating gear to rotate 90 degrees. One of the first torsion springs is twisted. The rotation of the rotating gear drives the filter frame to rotate 90 degrees, and the filter frame rotates 90 degrees to dump the sediment. When one of the filter frames continues to rotate, it will disengage from the rack, and one of the first torsion springs resets to drive one of the filter frames to reset. The filter frame rotates 90 degrees to maintain a horizontal position and then rotates between the feeding frame and the discharging frame. Then, the operator shuts down the motor. In this way, after the filter frame filters the sewage, it will be automatically replaced, which can improve the efficiency of sewage de-sludging.

[0010] 2. During the reverse rotation of the turntable, it will hit the flapping rod, causing the flapping rod to swing, and the second torsion spring is twisted. When the turntable and the flapping rod disengage, the second torsion spring drives the flapping rod to reset, causing the flapping rod to strike the filter frame. In this way, the sediment on the filter frame can be slapped off, enabling the sediment on the filter frame to be dumped better and further improving the efficiency of sewage de-sludging.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present utility model will be further described below with reference to the embodiments shown in the drawings.

[0017] Embodiment 1: A sludge removal device for sewage treatment, as Figures 1-4As shown in the figure, it includes a base 1, on which a housing 2 is placed. Inside the housing 2, a feeding frame 3 is fixedly connected, and a discharging frame 4 is also fixedly connected inside the housing 2. The discharging frame 4 is located below the feeding frame 3. Inside the housing 2, a filtering mechanism and a flapping mechanism are provided. The filtering mechanism is used to filter sediment, and the flapping mechanism is used to remove the sediment on the filtering mechanism, so that the filtering mechanism can filter sediment better and improve the filtering efficiency.

[0018] The filtering mechanism includes a bracket 5. The bracket 5 is fixedly connected to the inner bottom of the housing 2. A rotating shaft 6 is rotatably connected to the bracket 5. A overrunning clutch 7 is fixedly connected to the bottom of the rotating shaft 6. A spur gear 8 is fixedly connected to the overrunning clutch 7.

[0019] The filtering mechanism further includes a rotating block 9. Two rotating blocks 9 are rotatably connected to the rotating shaft 6. The two rotating blocks 9 are symmetrically arranged. Rotating gears 10 are fixedly connected to both of the rotating blocks 9. A toothed rod 101 is fixedly connected to the bracket 5. The toothed rod 101 meshes with one of the rotating gears 10. Torsion springs I 11 are connected between the two rotating gears 10 and the rotating shaft 6 respectively. Filter frames 12 are fixedly connected to both of the rotating blocks 9. The filter frames 12 and the rotating gears 10 on the same side are in a group. One of the filter frames 12 is located between the feeding frame 3 and the discharging frame 4.

[0020] The filtering mechanism further includes a motor 13. The motor 13 is fixedly connected to the inner bottom of the housing 2. A transmission gear 14 is fixedly connected to the output shaft of the motor 13. The transmission gear 14 meshes with the spur gear 8.

[0021] At first, the rack 101 meshes with one of the rotating gears 10. One of the filter frames 12 away from the feeding frame 3 is perpendicular to the horizontal plane and remains vertical. One of the torsion springs 11 is twisted. Then the operator first pours the sewage to be dewatered into the feeding frame 3. The sewage passes through the other filter frame 12, and the other filter frame 12 filters out the sediment in the sewage. The sewage is discharged through the discharge frame 4. After filtering for a period of time, the operator stops pouring sewage into the feeding frame 3. The operator starts the motor 13. The output shaft of the motor 13 drives the transmission gear 14 to rotate. The rotation of the transmission gear 14 drives the column gear 8 to rotate. The column gear 8 drives the rotating shaft 6 to rotate 180 degrees through the overrunning clutch 7. During the rotation of the rotating shaft 6, the rotating shaft 6 drives the two rotating blocks 9 and the two filter frames 12 to rotate. The filter frame 12 between the feeding frame 3 and the discharge frame 4 moves away from below the feeding frame 3. Subsequently, the rotating gear 10 in the same group as this filter frame 12 meshes with the rack 101, causing the rotating gear 10 to rotate 90 degrees. One of the torsion springs 11 is twisted. The rotation of the rotating gear 10 drives the filter frame 12 to rotate 90 degrees. The rotation of the filter frame 12 by 90 degrees dumps the sediment. When one of the filter frames 12 continues to rotate, it will disengage from the rack 101. One of the torsion springs 11 resets to drive one of the filter frames 12 to reset. The filter frame 12 rotates 90 degrees to be horizontal and then rotates to between the feeding frame 3 and the discharge frame 4. Then the operator shuts down the motor 13. After the filter frame 12 filters the sewage in this way, it will be automatically replaced, which can improve the efficiency of sewage de-sludging.

[0022] Embodiment 2: On the basis of Embodiment 1, as Figures 2-4 shown, the flapping mechanism includes a turntable 15. The turntable 15 is fixedly connected to the transmission gear 14. A flapping rod 16 is rotatably connected to the bracket 5. A torsion spring 17 is connected between the flapping rod 16 and the bracket 5. The rotation of the turntable 15 will drive the flapping rod 16 to swing. The swing of the flapping rod 16 will flap the filter frame 12, so that the sediment on the filter frame 12 can be dumped better, further improving the efficiency of sewage de-sludging.

[0023] After the filter frame 12 that has filtered the sewage rotates 180 degrees to maintain a vertical state, the operator starts the motor 13 to rotate in the reverse direction. The output shaft of the motor 13 rotates in the reverse direction to drive the turntable 15 to rotate in the reverse direction. Due to the one-way rotation of the overrunning clutch 7, the rotating gear 10 idles. During the reverse rotation of the turntable 15, it will hit the flapping rod 16, causing the flapping rod 16 to swing. The torsion spring 17 is twisted. When the turntable 15 and the flapping rod 16 disengage, the torsion spring 17 drives the flapping rod 16 to reset, causing the flapping rod 16 to strike the filter frame 12. In this way, the sediment on the filter frame 12 can be slapped off, so that the sediment on the filter frame 12 can be dumped better, further improving the efficiency of sewage de-sludging.
