Domestic wastewater refers to the washing water discharged by residents in their daily lives. In fact, only a small part of the wastewater has been treated. Most of it is directly discharged into rivers without treatment, which will cause serious pollution to the environment. Sewage treatment needs to pass through a filtration device;

[0003] When using a current sewage treatment filter device, sewage is passed into the filter device, and the internal filter screen filters the residue in the water to treat the sewage. When a lot of residue is stuck inside the filter screen, a cleaning brush is used to clean the residue inside the filter screen to prevent the residue from clogging the filter screen and affecting the sewage treatment efficiency.

The replacement of the cleaning brush is cumbersome, thereby reducing the sewage treatment efficiency of the filter.

[0022] In view of this, the utility model provides a filtering device for sewage treatment, which filters out the residue in the sewage through the filtering device. After the filter screen is flipped, the water inlet pipe allows clean water to enter the filter cylinder to backwash the filter screen. This cleaning method does not require the use of a cleaning brush to clean the filter screen, and does not require regular replacement of the cleaning brush. The main body of the filtering device is more convenient to use, thereby improving the sewage treatment efficiency of the filtering device.

[0024] In the specific implementation process, it is worth noting that the model of the first servo motor 24 is SM80-D601930. When the first servo motor 24 is working, it drives the stirring rod 23 to stir the sewage through the rotating rod 22;

[0025] Specifically, when the sewage treatment filter device is used, the first servo motor 24 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the stirring rod 23 to rotate to stir the sewage. When the stirring rod 23 rotates, it can clean the inner wall of the filter device body 1.

[0026] Example 2: By Figure 1 、 2As can be seen from Figure 3, the inner wall of the filter body 1 is provided with a control feeding device 3, which includes: a storage box 31, which is mounted on the inner wall of the filter body 1; a T-shaped plate 32, which is movably connected to the inner wall of the storage box 31; a spring 33, which is sleeved on the outer wall of the T-shaped plate 32 and fixedly connected to the outer wall of the storage box 31; a cam 34, which fits the outer wall of the T-shaped plate 32; a bevel gear set 35, which is mounted on the outer wall of the cam 34; a connecting portion 36, which is mounted on the outer wall of the bevel gear set 35 and is rotatably connected to the inner wall of the filter body 1 through a bearing, and the connecting portion 36 is rotatably connected to the outer wall of the rotating rod 22; wherein, after the connecting portion 36 is connected to the rotating rod 22, when the connecting portion 36 rotates, the cam 34 is driven to rotate through the bevel gear set 35, and the cam 34 squeezes the T-shaped plate 32 to compress the spring 33;

[0027] In the specific implementation process, it is worth noting that the bevel gear set 35 is composed of two meshing bevel gears, and the connecting portion 36 connects the bevel gear set 35 and the rotating rod 22 together. The rotating rod 22 drives the cam 34 to squeeze the T-shaped plate 32 to move through the bevel gear set 35, and the T-shaped plate 32 compresses the spring 33;

[0028] Specifically, on the basis of the above-mentioned embodiment 1, the disinfectant is added to the inside of the storage box 31, the connecting part 36 connects the bevel gear set 35 and the rotating rod 22 together, the rotating rod 22 drives the cam 34 to rotate through the bevel gear set 35, and the cam 34 squeezes the T-shaped plate 32 to move, and the T-shaped plate 32 compresses the spring 33, and the T-shaped plate 32 blocks the bottom of the storage box 31, thereby controlling the disinfectant inside the storage box 31 to fall into the inside of the filter device body 1 at a uniform speed.

[0029] Example 3: By Figure 1 、 2 As can be seen from Figures 3 and 4, the connecting portion 36 includes: a rotating drum 361, which is rotatably connected to the inner wall of the filter device body 1 via a bearing and is fixedly connected to the outer wall of the bevel gear set 35. The inner wall of the rotating drum 361 is rotatably connected to the outer wall of the rotating rod 22; a bolt 362, which is threadedly connected to the inner wall of the rotating drum 361 and plugged into the outer wall of the rotating rod 22. When the bolt 362 rotates, it inserts into the inner wall of the rotating rod 22. When the rotating rod 22 rotates, the bevel gear set 35 is driven to rotate via the rotating drum 361.

[0030] In the specific implementation process, it is worth noting that the torsion bolt 362 is inserted into the interior of the rotating rod 22, and when the rotating rod 22 rotates, the bevel gear set 35 is driven to rotate through the rotating cylinder 361;

[0031] Furthermore, a filter cartridge 4 is installed on the top of the filter device body 1, a water inlet pipe 6 is installed on the inner wall of the filter cartridge 4, a sewage pipe 7 is installed on the inner wall of the filter cartridge 4, a connecting pipe 8 is installed on the bottom of the filter cartridge 4 and is fixedly connected to the inner wall of the filter device body 1, a sewage pipe 9 is installed on the outer wall of the connecting pipe 8, and a drain pipe 10 is installed on the outer wall of the filter device body 1;

[0032] In the specific implementation process, it is worth noting that clean water enters the filter cartridge 4 from the water inlet pipe 6, and sewage enters the filter cartridge 4 from the sewage pipe 7. The connecting pipe 8 discharges the water inside the filter cartridge 4 into the filter device body 1. The sewage pipe 9 discharges the cleaned residue to the outside. The drain pipe 10 facilitates the discharge of the cleaned sewage to the outside.

[0033] Specifically, based on the above-mentioned embodiment 1, the staff twists the bolt 362 to rotate, and the bolt 362 is inserted into the inner wall of the rotating rod 22. The bolt 362 fixes the rotating cylinder 361 and the rotating rod 22 together, and the rotating rod 22 drives the bevel gear set 35 to rotate through the rotating cylinder 361. Clean water enters the filter cylinder 4 from the water inlet pipe 6, and the sewage pipe 7 discharges the sewage into the filter cylinder 4. The water inside the filter cylinder 4 is discharged into the inside of the filter device body 1 through the connecting pipe 8. The cleaned residue is discharged from the sewage pipe 9, and the drain pipe 10 facilitates the discharge of cleaned sewage.

[0034] Example 4: By Figure 1 、 2 As shown in Figures 4 and 5, a filtering device 5 is provided on the inner wall of the filter cartridge 4. The filtering device 5 includes: a filter screen 51, which is rotatably connected to the inner wall of the filter cartridge 4 through a sealed bearing; a gear 52, which is mounted on one side of the filter screen 51; a rack 53, which is engaged with the outer wall of the gear 52; and an electric push rod 54, which is detachably mounted on the top of the rack 53 and is detachably connected to the outer wall of the filter cartridge 4; wherein the electric push rod 54 drives the filter screen 51 on one side of the gear 52 to rotate through the rack 53.

[0035] In the specific implementation process, it is worth noting that the model of the electric push rod 54 is TG-700. The electric push rod 54 drives the filter screen 51 on one side of the gear 52 to rotate through the rack 53. The mesh size of the filter screen 51 is not specifically limited and can meet the use requirements. Those skilled in the art should understand it in a broad sense to meet the technical characteristics of this case.

[0036] Specifically, based on the above-mentioned embodiment 1, when the electric push rod 54 is working, it drives the rack 53 to move, the rack 53 drives the gear 52 to rotate, and the gear 52 drives the filter screen 51 to rotate. The filter screen 51 rotates one hundred and eighty degrees. After the sewage pipe 9 is closed, clean water enters the inside of the filter cartridge 4 from the water inlet pipe 6 to backwash the filter screen 51. At the same time, the solenoid valve on the outer wall of the connecting pipe 8 works to connect the sewage pipe 9 with the filter cartridge 4, so that the clean water is discharged together with the residue. The solenoid valve is a prior art and those skilled in the art should understand it in a broad sense to meet the technical characteristics of this case.
