[0067] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0068] like Figure 1 and Figure 2 As shown, the utility model provides a sewage treatment pool, including a pool body 1, a bridge frame 2, a rotating assembly 3 and a slag skimming assembly 4, the bridge frame 2 is connected to the pool body 1; the rotating assembly 3 includes a rotating member 31 and a driving member 32, the rotating member 31 is rotatably connected to the bridge frame 2, the driving member 32 is connected to the bridge frame 2 and the rotating member 31, and is used to drive the rotating member 31 to rotate; the slag skimming assembly 4 includes a slag discharge trough 41, an elastic member 42 and a slag skimming member 43, the slag discharge trough 41 is slidably connected to the pool body 1 along the vertical direction, the elastic member 42 connects the slag discharge trough 41 and the pool body 1, and is used to provide elastic force for the sliding slag discharge trough 41 to reset; the slag skimming member 43 is connected to the rotating member 31, and is used to rotate and skim the floating slag into the slag discharge trough 41.

[0069] Specifically, the bridge frame 2 is connected to the pool body 1 to provide support for the rotating component 3 and the skimming member 43. The rotating member 31 is driven to rotate by the driving member 32. The rotating rotating member 31 drives the skimming member 43 to rotate. The skimming member 43 drives the slag on the water surface to rotate. When it rotates close to the slag discharge groove 41, it pushes the slag discharge groove 41 to slide downward. When the slag pushed by the skimming member 43 moves to the top of the slag discharge groove 41, the slag enters the slag discharge groove 41 and is discharged through the slag discharge groove 41, thereby realizing automatic skimming and reducing manual labor intensity. When the slag discharge groove 41 slides downward, the elastic member 42 is compressed to accumulate reset elastic force. When the skimming plate 432 slides over the slag discharge groove 41, the slag discharge groove 41 slides and resets under the elastic force of the elastic member 42.

[0070] By slidingly connecting the slag discharge chute 41 to the pool body 1, the slag discharge chute 41 can slide downward under the abutment of the slag skimmer 43, so that the slag can be moved to the slag discharge chute 41 without or slightly out of the water surface, thereby reducing the problem of slag overflowing from both ends of the slag skimmer 43 due to the slag being out of the water surface.

[0071] It should be understood that the driving member 32 may be a direct drive motor, a combination of a motor and a reducer, or a combination of a motor and a belt transmission mechanism or a gear transmission mechanism.

[0072] It should be understood that the elastic member 42 can be a spring, an elastic strip, an elastic block, etc.

[0073] It should be understood that the rotating member 31 can be a rotating bracket, a rotating rod, etc. The bottom of the rotating member 31 can be rotatably connected to the bottom inner wall of the pool body 1, or can be spaced apart from the bottom inner wall of the pool body 1.

[0074] It should be understood that the slag discharge chute 41 can be slidably connected to the tank body 1 by means of a slider, a slide groove, etc.

[0075] like Figure 5 and Figure 6 As shown, in one of the embodiments, the skimming assembly 4 also includes a connecting member 44, and the connecting member 44 includes a connecting bracket 441 and a sliding bracket 442. One side of the connecting bracket 441 is connected to the inner wall of the pool body 1, and the other side is provided with a slide groove in the vertical direction. The sliding bracket 442 can be slidably inserted in the slide groove and connected to the slag discharge trough 41. The elastic member 42 connects the connecting bracket 441 and the slag discharge trough 41, and is connected to the pool body 1 via the connecting bracket 441.

[0076] The slag discharge chute 41 is slidably connected to the tank body 1 by connecting the bracket 441 and the sliding bracket 442 .

[0077] like Fig. 9 and Fig.10 As shown, in one embodiment, the skimming member 43 includes a connecting rod 431 and a skimming plate 432 . The connecting rod 431 is connected to the rotating member 31 and is arranged along the radial direction of the pool body 1 ; the skimming plate 432 is connected to the connecting rod 431 .

[0078] Specifically, when the driving member 32 drives the rotating member 31 to rotate, the connecting rod 431 rotates along with the rotating member 31, and the skimming plate 432 is connected to the connecting rod 431. As the connecting rod 431 rotates, the skimming plate 432 performs a circular motion in the pool body 1; during the movement, the skimming plate 432 pushes the scum on the water surface toward the slag discharge trough 41, causing it to fall into the slag discharge trough 41.

[0079] It should be understood that the skimming plate 432 can be rotatably connected to the connecting rod 431 or can be fixedly connected to the connecting rod 431.

[0080] like Fig. 9 and Fig.10 As shown, in one of the embodiments, the skimming plate 432 is rotatable around the axis of the connecting rod 431 and connected to the connecting rod 431; the skimming member 43 also includes an elastic portion 433, which connects the skimming plate 432 and the connecting rod 431, and the elastic portion 433 is used to provide a restoring elastic force to the rotating skimming plate 432, so that the skimming plate 432 can rotate and also push the slag discharge chute 41 to slide downward.

[0081] Specifically, when the skimming plate 432 pushes the slag to abut the slag discharge trough 41, the skimming plate 432 can rotate slightly relative to the slag discharge trough 41, and while rotating, pushes the slag discharge trough 41 to descend until it slides to the top of the slag discharge trough 41. At this time, the skimming plate 432 stops rotating relative to the connecting rod 431. Through the above-mentioned arrangement, the slag can be slightly separated from the water surface while reducing the sliding distance of the slag discharge trough 41, thereby preventing the slag discharge trough 41 from descending to the water surface and preventing water from directly entering the slag discharge trough 41 from the top of the slag discharge trough 41.

[0082] It should be understood that the elastic portion 433 may be a torsion spring, an elastic strip, an elastic block, etc.

[0083] like Figure 4 and Figure 7 As shown, in one of the embodiments, a slag inlet channel is opened at the top of the slag discharge trough 41; the slag skimming assembly 4 also includes a plurality of support bars 45, and the plurality of support bars 45 are arranged along the length direction of the slag discharge trough 41, the support bars 45 are connected to the slag discharge trough 41, and the top of the support bars 45 is flush with the top of the slag discharge trough 41.

[0084] By opening a slag inlet channel at the top of the slag discharge trough 41, the floating slag can enter the slag discharge trough 41 from the slag discharge channel at the top of the slag discharge trough 41. By setting a plurality of support bars 45, when the slag skimming plate 432 slides over the top of the slag discharge trough 41, in order to prevent the slag skimming plate 432 from sliding into the slag discharge trough 41, a plurality of support bars 45 are set. The support bars 45 are flush with the top of the slag discharge trough 41, which can prevent the sliding slag skimming plate 432 from sliding into the slag discharge trough 41.

[0085] like Figure 7 As shown, in order to allow the slag entering the slag discharge trough 41 to be discharged smoothly from the slag discharge trough 41, in one embodiment, a notch 41a is provided on one side of the slag discharge trough 41, and the notch 41a is used to supply water to enter the slag discharge trough 41 when the slag discharge trough 41 descends to a preset height.

[0086] When the skimming plate 432 pushes the slag discharge trough 41 to slide downward, the floating slag enters the slag discharge trough 41. The gap 41a is located below the water surface, and water can enter the slag discharge trough 41 through the gap 41a. The water entering the slag discharge trough 41 can drive the floating slag to flow out of the slag discharge trough 41. Moreover, by controlling the size of the gap 41a, a limited and small amount of water can enter the slag discharge trough 41 through the gap 41a.

[0087] like Figure 4 and Figure 8As shown, in one of the embodiments, a slag discharge port 41b connected to the slag inlet channel is opened at the bottom of the slag discharge trough 41; the slag skimming assembly 4 also includes a slag discharge part 46, the slag discharge part 46 includes a first slag discharge pipe 461, a telescopic pipe 462 and a second slag discharge pipe 463, one end of the first slag discharge pipe 461 is connected to the slag discharge port 41b, one end of the telescopic pipe 462 is connected to the first slag discharge pipe 461, and the second slag discharge pipe 463 is fixed to the pool body 1, and one end is connected to the other end of the telescopic pipe 462.

[0088] After the slag skimming plate 432 pushes the slag into the slag discharge trough 41, the slag enters the first slag discharge pipe 461 through the slag discharge port 41b, one end of the contraction pipe is connected to the first slag discharge pipe 461, and the other end is connected to the second slag discharge pipe 463. The telescopic pipe 462 can automatically expand and contract according to the height change of the slag discharge trough 41 to keep the slag discharge pipe unobstructed, and the second slag discharge pipe 463 is fixed to the tank body 1 to discharge the slag from the tank body 1 to a designated location for treatment.

[0089] It should be understood that the telescopic tube 462 may be a bellows, two tubes connected in a sliding manner, or the like.

[0090] like Figure 4 As shown, in one embodiment, the bottom inner wall of the tank body 1 is inclined downward in a direction close to the slag discharge port 41b.

[0091] Specifically, after the skimming plate 432 pushes the slag into the slag discharge trough 41, the slag enters the first slag discharge pipe 461 through the slag discharge port 41b; because the inner wall of the bottom of the tank body 1 is inclined downward in the direction close to the slag discharge port 41b, the slag is more likely to slide down to the slag discharge port 41b along the inclined inner wall under the action of gravity, thereby improving the slag discharge efficiency; the inclined inner wall helps to reduce the deposition of slag at the bottom of the slag discharge trough 41, reducing the difficulty of cleaning. Figure 1 and Figure 2 As shown, in one embodiment, the slag skimming assembly 4 also includes an inner retaining ring 47 and an outer retaining ring 48. The inner retaining ring 47 is connected to the connecting rod 431 and is arranged between the center of the pool body 1 and the slag discharge groove 41; the outer retaining ring 48 is sleeved on the slag discharge groove 41 and is coaxially arranged with the pool body 1.

[0092] Specifically, the inner retaining ring 47 is located between the center of the tank body 1 and the slag discharge groove 41, and is used to prevent the floating slag from spreading to the center of the tank body 1 and guide the floating slag to move to the slag discharge groove 41; the outer retaining ring 48 is sleeved on the slag discharge groove 41 and is coaxially arranged with the tank body 1, and is used to prevent the floating slag from overflowing from the edge of the slag discharge groove 41, and ensure that the floating slag smoothly enters the slag discharge groove 41. When the slag skimming plate 432 pushes the floating slag into the slag discharge groove 41, the inner retaining ring 47 and the outer retaining ring 48 work together to make the floating slag flow to the slag discharge groove 41 in a concentrated manner, thereby improving the slag skimming effect.

[0093] It should be understood that the inner retaining ring 47 can be connected to the connecting rod 431 through bolts, screws and brackets, and the outer retaining ring 48 can be connected to the inner wall of the cell body 1 through a bracket. The above connection can also be achieved through other connection structures.

[0094] like Figure 4 As shown, in one embodiment, the slag skimming assembly 4 further includes a guide plate 49 , which is connected to the slag discharge chute 41 , and the guide plate 49 has a guide slope, which gradually rises toward the direction approaching the slag discharge chute 41 .

[0095] When the slag skimming plate 432 pushes the slag into the slag discharge trough 41, the slag and the slag skimming plate 432 move upward along the guide slope of the guide plate 49; because the guide slope gradually rises toward the direction close to the slag discharge trough 41, the slag is subjected to an upward force on the guide slope, making it easier for it to climb over the guide plate 49 and enter the slag discharge trough 41. After climbing over the guide plate 49, the slag slides along the slag discharge trough 41 to the slag discharge port 41b, and is finally discharged from the tank body 1 through the slag discharge member 46.

[0096] like Figure 1 and Figure 3 As shown, it should be understood that the sewage treatment pool in the utility model is provided with an overflow port for water supply overflow at the top, a mud discharge port at the bottom, and a scraper plate 5 connected to the rotating part 31 at the bottom. This is the existing technology and will not be elaborated in this application.

[0097] The utility model also relates to a water outlet filtering device, comprising the above-mentioned sewage treatment pool.

[0098] It should be understood that the effluent filtration device may also include an anaerobic tank (not shown in the figure), a secondary sedimentation tank (not shown in the figure), a biochemical tank (not shown in the figure) and a regulating tank (not shown in the figure).

[0099] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
