[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0040] The following is combined Figures 1-6 The water distribution device of the present invention is described.

[0041] like Figure 1 As shown, the water distribution device disclosed in this embodiment of the invention is installed in the water distribution channel of the sedimentation tank, including a guide cylinder assembly 1 and a water distribution assembly 2. The guide cylinder assembly 1 penetrates the bottom of the water distribution channel, that is, the top of the guide cylinder assembly 1 is located above the bottom of the water distribution channel, and the bottom is located below the bottom of the water distribution channel. The water distribution assembly 2 is located at the bottom of the guide cylinder assembly 1, and the bottom end of the water distribution assembly 2 extends along the extension direction of the water distribution channel. A guide plate 3 is provided in the middle of the bottom end of the water distribution assembly 2.

[0042] The water distribution device provided by the application can realize uniform water distribution by guiding the mixed liquid to be precipitated along the water distribution wing through the water distribution assembly 2 due to the extension of the bottom end of the water distribution assembly 2 along the extension direction of the water distribution channel and the arrangement of the flow guide plate.

[0043] Specifically, as shown in Figure 2 and Figure 3 , the guide cylinder assembly 1 comprises a fixed lug 11, a water distribution guide cylinder 12 and a connecting inner cylinder 13. The fixed lug 11 is arranged on the top of the bottom of the water distribution channel and can be fixed in the water distribution channel through a fixing screw 4. The fixed lug 11 is perpendicular to the axis of the water distribution guide cylinder 12 and is symmetrical on both sides of the water distribution guide cylinder 12. The shape of the fixed lug 11 can be circular, rectangular or polygonal. The fixed lug 11 is provided with bolt holes on both sides. The fixed lug 11 can be fixed on the bottom of the water distribution channel through the fixing screw 4. The fixed lug 11 is arranged on the top of the water distribution guide cylinder 12. The upper end of the water distribution guide cylinder 12 is open, and the lower end is open. The water distribution guide cylinder 12 is a hollow cylindrical body. The connecting inner cylinder 13 is arranged at the bottom of the water distribution guide cylinder 12, and the connecting inner cylinder 13 is coaxial with the water distribution guide cylinder 12. The inner diameter of the connecting inner cylinder 13 is the same as the inner diameter of the water distribution guide cylinder 12, and the outer diameter is 3-5mm smaller than the outer diameter of the water distribution guide cylinder 12, so that the outer part of the guide cylinder assembly 1 forms a circular truncated cone, which can provide installation limiting conditions for the installation of the water distribution assembly 2.

[0044] Specifically, the inner diameter of the water distribution guide cylinder 12 can be 50-100mm, or any other size according to actual use needs.

[0045] Further, as shown in Figure 4 and Figure 5 , the water distribution assembly 2 comprises a connecting outer cylinder 21 and a water distribution wing 22. The connecting outer cylinder 21 is sleeved outside the connecting inner cylinder 13. The water distribution wing 22 is arranged at the bottom of the connecting outer cylinder 21 and extends along the extension direction of the water distribution channel. The bottom end of the water distribution wing 22 is provided with a flow guide plate 3 corresponding to the water outlet of the connecting outer cylinder 21. The connecting outer cylinder 21 is arranged at the top of the water distribution wing 22 and is centrally arranged. The water distribution wing 22 is arranged symmetrically along the axis of the connecting outer cylinder 21. The flow guide plate 3 guides the mixed liquid to be precipitated in the precipitation tank and realizes uniform water distribution along the water distribution wing 22.

[0046] The bottom surface of the water distribution wing 22 is open, and the top surface and the side surface are closed structures. Specifically, the water distribution wing 22 comprises a top plate 221, a long side plate 222 and a short side plate 223. The top plate 221 is connected with the connecting outer cylinder 21, and the cross-sectional shape of the top plate 221 can be a circular arc or a triangle. The width and height of the top plate from the center to the end are gradually reduced, and the angle formed by the size reduction is 3°-8°. The long side plate 222 has a pair, and the pair of long side plates 222 are correspondingly arranged at the bottom of the two long side edges of the top plate. The short side plate 223 has a pair, and the pair of short side plates 223 are correspondingly arranged at the bottom of the two short side edges of the top plate 221. The two ends of the flow guide plate 3 are connected with the two long side plates 222, thereby realizing the flow guiding effect of the mixed liquid. The length of the water distribution wing 22 is 500-800 mm.

[0047] Further, the cross-sectional shape of the flow guide plate 3 can be an arch shape, and the diameter of the arch shape is greater than the diameter of the connecting outer cylinder 21. The cross-sectional shape of the flow guide plate 3 can also be a triangle, and the length of the base of the triangle is not less than the diameter of the connecting inner cylinder 13, so as to ensure that the mixed liquid flowing down from the connecting inner cylinder 13 can smoothly distribute water along the flow guide plate 3.

[0048] In the embodiment of the present application, a plurality of partitions 5 are arranged in the interior of the water distribution wing 22. The side edges of the partitions 5 are connected with the top plate 221 and the long side plate 222, and the partitions 5 extend from the center to the two ends of the water distribution wing 22. The arrangement of the partitions 5 divides the interior space of the water distribution wing 22 into a plurality of flow channels 6, thereby realizing uniform water distribution.

[0049] As shown in the drawings, Figure 6 In the embodiment of the present application, when the mixed liquid to be precipitated needs to have the need to intercept large garbage, the water distribution device further comprises a grid cap 7. The grid cap 7 is arranged at the water inlet of the water distribution guide cylinder 12. The grid cap 7 can be arranged in a spherical or spherical crown shape to increase the surface area of filtration. The grid gap of the grid cap 7 can be 5-40 mm, or can be arranged in any other size according to actual use needs. The bottom of the grid cap 7 is provided with a threaded connection joint, and the top of the water distribution guide cylinder 12 is provided with a thread, so that the grid cap 7 and the water distribution guide cylinder 12 are threadedly connected.

[0050] As shown in the drawings, Figure 7 The shape of the grid cap 7 can also be cylindrical, which can increase the surface area of filtration.

[0051] Another aspect of the embodiment of the present application is to provide a side-in and side-out sedimentation tank, which can be a rectangular side-in and side-out sedimentation tank or a circular side-in and side-out sedimentation tank. The water distribution device described above can realize uniform water distribution of the mixed liquid.
