[0020] The present application is provided with the following description with reference to the accompanying drawings to help comprehensively understand various embodiments of the present application as defined in the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as just exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present application.

[0021] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0023] An embodiment of this utility model provides a disturbance-resistant sedimentation tank, such as... Figures 1-3 As shown, it includes: a pool body 1, an inlet pipe 2, an anti-disturbance device 301 installed at the end of the inlet pipe 2, and an outlet 102. The anti-disturbance device 301 includes a first outlet pipe 302 connected to the end of the inlet pipe 2 and a second outlet pipe 303 sleeved outside the first outlet pipe 302. A slow-flow space 304 is formed between the first outlet pipe 302 and the second outlet pipe 303. The first outlet pipe 302 is provided with a first outlet hole 305 for discharging the liquid in the inlet pipe 2 into the slow-flow space 304, and the second outlet pipe 303 is provided with a second outlet hole 306 for discharging the liquid in the slow-flow space 304 into the pool body 1.

[0024] The liquid first enters the first outlet pipe 302 through the inlet pipe 2, then enters the slow-flow space 304 through the first outlet hole 305, and subsequently enters the tank body 1 through the second outlet hole 306. Finally, it overflows through the outlet 102 to be discharged. This process gradually reduces the inlet water flow velocity, minimizing direct impact on the bottom or sidewalls of the tank body 1, reducing water flow disturbance, and making the water in the sedimentation tank more stable. This is beneficial for the settling of solid particles, improves sedimentation efficiency, and reduces the resuspension of sediment caused by water flow disturbance. The first outlet hole 305 of the first outlet pipe 302 can be located on the sidewall or bottom of the first outlet pipe 302; the second outlet hole 306 of the second outlet pipe 303 can be located on the sidewall, top, or bottom of the second outlet pipe 303. This anti-disturbance device 301 mainly consists of the first outlet pipe 302 and the second outlet pipe 303. It has a simple structure, low cost, and good anti-disturbance effect.

[0025] In some embodiments, such as Figure 3 As shown, the first water outlet 305 includes a plurality of first side holes 307 disposed around the first water outlet pipe 302.

[0026] In this embodiment, the first side hole 307 is disposed on the side wall of the first water outlet pipe 302, which makes the water outlet more uniform and further reduces the flow rate.

[0027] Further, as shown in Figure 3 The second water outlet hole 306 comprises a plurality of second side holes 308 arranged on the side of the second water outlet pipe 303.

[0028] The second side holes 308 can be arranged on the side wall of the upper, middle or lower part of the second water outlet pipe 303. The arrangement position of the second side holes 308 depends on the length of the second water outlet pipe 303 and the assembly relationship between the second water outlet pipe 303 and the first water outlet pipe 302. In some embodiments, the bottom of the first water outlet pipe 302 and the second water outlet pipe 303 are assembled together, the first side holes 307 of the first water outlet pipe 302 are arranged at the bottom, and the second side holes 308 are arranged as Figure 1 In some embodiments, the anti-disturbance effect is better when the second side holes 308 are arranged at the middle or upper part of the second water outlet pipe 303; the first side holes 307 are arranged at the middle or upper part, and the second side holes 308 are arranged as Figure 2 In another embodiment, the second side holes 308 are preferably arranged at the lower part of the second water outlet pipe 303.

[0029] Further, as shown in Figures 1-2 The first water outlet pipe 302 and the second water outlet pipe 303 are provided with an exhaust pressure relief structure 6 above.

[0030] Because the first water outlet pipe 302 is affected by the water pressure from the water pump in the inlet pipe 2, the water pressure is large, and the exhaust pressure relief structure 6 is arranged to realize external pressure relief of the first water outlet pipe 302, without affecting the pressure in the second water outlet pipe 303, further realizing the effect of preventing disturbance of water flow.

[0031] In some embodiments, as shown in Figures 1-3 The bottom of the pool body 1 has a sediment layer 4, and the water outlet 102 and the sediment layer 4 are provided with an anti-disturbance layer 501.

[0032] When the liquid enters the sediment tank, the particles with a density greater than water will gradually sink due to gravity, and the sediment layer 4 is the area where these sinking solid particles gradually accumulate at the bottom of the sediment tank. The anti-disturbance layer 501 is arranged at different positions according to different water outlet conditions, which can Figure 1 An embodiment shown further reduces the influence of incoming water on the sediments in the sediment layer 4, thereby reducing the influence on the water outlet effect; and can also Figure 3 Another embodiment shown prevents the sediments in the sediment layer 4 from rising to the water outlet, and the sediment layer 4 further slows down the disturbance of water flow to the water outlet.

[0033] Further, as shown in Figure 1 The second water outlet hole 306 is arranged below the first water outlet hole 305, and the anti-disturbance layer 501 is arranged above the second water outlet hole 306.

[0034] As shown in Figure 3In the embodiment, the second water outlet hole 306 is arranged at the lower part of the second water outlet pipe 303, the water flow flows from the first water outlet hole 305 at the middle or upper part of the first water outlet pipe 302 into the slow flow space 304, and then falls to the side of the second water outlet hole 306 below the first water outlet hole 305 to be slowly discharged into the pool body 1, which is matched with the anti-disturbance layer 501 arranged above the second water outlet hole 306, so that the anti-disturbance effect is good, the sediment flow is further organized to the water outlet 102, and the sedimentation effect is improved.

[0035] Further, as shown in Figures 2-3 , the second water outlet hole 306 is arranged above the first water outlet hole 305, and the anti-disturbance layer 501 is arranged below the second water outlet hole 306.

[0036] In the embodiment, the second water outlet hole 306 is arranged at the upper part of the second water outlet pipe 303, the water flow flows from the first water outlet hole 305 at the bottom of the first water outlet pipe 302 into the slow flow space 304, and then rises to the side of the second water outlet hole 306 above the first water outlet hole 305 to be discharged into the pool body 1, which occupies a small space, and is matched with the anti-disturbance layer 501 arranged below the second water outlet hole 306, so that the anti-disturbance effect on the sedimentation layer 4 is good.

[0037] Further, as shown in Figure 2 , the sleeve 311 is arranged outside the second water outlet pipe 303, and the bottom side of the sleeve 311 abuts against the anti-disturbance layer 501.

[0038] In practice, since the carbon powder structure is heavy, the anti-disturbance device 301 is arranged at a certain distance from the water outlet, and the water inflow that has not been subjected to sedimentation treatment has little effect on the water that has completed sedimentation at the water outlet. However, the arrangement of the sleeve 311 can further isolate the water flow on the water inflow side and the water outflow side, so that the anti-disturbance device 301 has wider applicability and does not affect the water outflow while preventing disturbance.

[0039] Further, as shown in Figures 1-2 , the anti-disturbance layer 501 includes a support frame 502 arranged above the sedimentation layer 4 and an anti-disturbance filler rolled up or stacked in multiple layers arranged on the support frame 502.

[0040] The support frame 502 is used to fix the anti-disturbance filler, and the anti-disturbance filler such as the porous PVC plastic filler is arranged below the second water outlet hole 306 in the form of rolling up or stacking in multiple layers, which can effectively reduce the water flow speed, reduce the impact of the water flow on the sedimentation layer 4, and effectively reduce the water inflow fluctuation.

[0041] In some embodiments, as shown in Figures 1-2 , the first water outlet pipe 302 and the second water outlet pipe 303 are connected through the connecting structure 309.

[0042] The first outlet pipe 302 and the second outlet pipe 303 are connected integrally and fixed relative to the pool body 1 on one side or by other fixing means, and the connection manner prevents disturbance of the device 301 and is good in integrity, and the position of the device in the pool body 1 can be changed at will. Further, as shown in Figure 1 , 3 The connecting structure 309 comprises a fastener arranged at the bottom of the first outlet pipe 302 and connected with the bottom of the second outlet pipe 303. The first outlet pipe 302 and the second outlet pipe 303 are connected by the fastener such as a screw and a nut, which is simple in structure, does not affect water flow, is convenient to connect and low in cost.
