[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] See Figure 1An environmentally friendly sedimentation tank includes an inlet pipe 31, a sedimentation tank body 1 with an outlet 11 at the top, a guide cylinder 2 disposed within the sedimentation tank body 1, and an inlet cylinder 3 disposed within the guide cylinder 2. A hopper 10 is located at the bottom of the sedimentation tank body 1, and the guide cylinder 2 is positioned above the hopper 10. The guide cylinder 2 is fixedly connected to the sedimentation tank body 1 via a first connecting member 20. The inlet cylinder 3 is fixedly connected to the guide cylinder 2 via a second connecting member. One end of the inlet pipe 31 is connected to the inlet cylinder 3. The other end of the inlet pipe 31 passes through the guide tube 2 and the sedimentation tank body 1 in sequence to form an inlet. The guide tube 2 has a guide port 21 on its side near the bottom. The sedimentation chamber 13 between the sedimentation tank body 1 and the guide tube 2 is provided with a honeycomb inclined tube packing 4. That is, the honeycomb inclined tube packing 4 fills the annular area between the guide tube 2 and the sedimentation tank body 1 to further settle the particulate matter. The honeycomb inclined tube packing 4 is located above the guide port 21 and does not obstruct the liquid from flowing out of the guide port 21.

[0023] See Figure 3 The sedimentation chamber 13 is provided with a packing support layer, which is located above the guide port 21. The packing support layer includes several packing support bars 5 fixedly connected to the sedimentation tank body 1. The packing support bars 5 can be channel steel. Several fixing rings 6 are fixedly connected to the upper side of the packing support layer and arranged around the guide cylinder 2. The fixing rings 6 can be threaded steel that has been bent into a ring shape. The honeycomb inclined tube packing 4 is fixed in the sedimentation chamber 13 through the fixing rings 6. The honeycomb inclined tube packing 4 is fixed to the fixing rings 6 by cable ties to prevent the honeycomb inclined tube packing 4 from shifting. The liquid can pass through the packing support layer and the fixing rings 6 and be filtered by the honeycomb inclined tube packing 4.

[0024] For another configuration of the filler support layer, please refer to [the relevant documentation]. Figure 4 The packing support layer includes at least six packing support bars 5 fixed between the sedimentation tank body 1 and the guide cylinder 2. The support bars 5 are evenly arranged, and a plurality of fixing rings 6 are fixedly connected to the upper side of the packing support layer, surrounding the guide cylinder 2. Compared with Figure 3 The filler support layer shown, Figure 4 The packing support layer shown makes the force on the fixing ring 6 more uniform, thereby enhancing the fixing effect of the honeycomb inclined tube packing 4.

[0025] See Figure 1 The longitudinal section of the liquid inlet cylinder 3 is smaller at the bottom and larger at the top. When the liquid flows to the top, the flow rate can be reduced and the residence time can be extended.

[0026] See Figure 1The sedimentation tank body 1 is coaxially arranged with the guide cylinder 2, and the guide cylinder 2 is coaxially arranged with the liquid inlet cylinder 3. This coaxial arrangement improves the overall structural stability of the equipment.

[0027] See also Figure 1 and Figure 2 The sedimentation tank 1 has an outlet trough 12 at the top, and the outlet trough 12 is arranged around the sedimentation tank 1 at least once. (See reference...) Figure 2 The water outlet trough 12 can be in the form of a triangular toothed structure. In other embodiments, the water outlet trough can also be in the form of a rectangular, trapezoidal or arc-shaped toothed structure.

[0028] See Figure 1 The bottom of the guide tube 2 is provided with a conical guide section 22, which can guide the liquid to flow out from the guide port 21 and prevent particulate matter from accumulating at the bottom of the guide tube 2.

[0029] See Figure 1 The hopper 10 is provided with a drain outlet 101 near the bottom.

[0030] See Figure 1 The first connector 20 includes a plurality of first support plates, which are arranged circumferentially around the guide tube 2 at intervals to enhance the firmness of the connection between the guide tube 2 and the sedimentation tank body 1.

[0031] Specifically, the second connector includes a plurality of second support plates.

[0032] The process and principle of raw liquid purification are as follows: First, the raw liquid enters from the inlet of the inlet pipe 31, passes through the inlet cylinder 3 and the guide cylinder 2, and enters the sedimentation tank 1. In the sedimentation tank 1, the raw liquid undergoes further sedimentation through the honeycomb inclined tube packing 4. The particles settle along the inclined tube and are deposited at the bottom of the sedimentation tank 1. The design of this application has multiple deflections, which greatly extends the residence time and improves the sedimentation filtration effect.

[0033] The raw materials include river water, industrial wastewater, and domestic sewage.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0035] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of this application and its equivalents, this application also intends to include such modifications and variations.
