Detailed implementation manners

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Such as Figures 1-4As shown in the figure, a multi-directional circulating sewage treatment device 100 in an embodiment of the present utility model includes a tank body 10, an aeration structure 20 and a baffle structure. An inlet 11, an outlet 12 and a sludge outlet 13 are respectively formed on the tank body 10. Sewage flows into the tank body 10 through the inlet 11, the supernatant after treatment and filtration flows out from the outlet 12, and the generated sludge is discharged from the sludge outlet 13. The baffle structure includes a first baffle 31 and a plurality of second baffles 32. The first baffle 31 is arranged inside the tank body 10 and extends along the axial direction of the tank body 10. It divides the interior of the tank body 10 into two parts, and a channel for sewage to flow through is formed between both ends of the first baffle 31 and the tank body 10, that is, there is a gap between both ends of the first baffle 31 and the inner wall of the tank body 10. A plurality of second baffles 32 are respectively arranged on both sides of the first baffle 31, and adjacent second baffles 32 are arranged up and down in a staggered manner, that is, one of the second baffles 32 is connected to the bottom of the tank body 10, leaving a space for sewage to flow above, and its adjacent second baffle 32 is connected to the top of the tank body 10, leaving a space for sewage to flow below. The aeration structure 20 extends into the tank body 10 and is used to convey gas to the sewage in the tank body 10.

[0027] Since the first baffle 31 divides the internal space of the tank body 10 into two parts, sewage flows from one end of the tank body 10 to the other end and then turns back, and so on. Moreover, when sewage flows between the second baffles 32 arranged up and down in a staggered manner, it will flow back and forth between the bottom and the top of the tank body 10. Therefore, when sewage flows in the tank body 10, horizontal and vertical movements are generated simultaneously, which can promote the water flow effect, prevent sludge accumulation, increase the water flow path, extend the reaction time, and improve the sewage treatment effect. At the same time, the aeration structure 20 is used to aerate the water body, so that the sludge in the water body is always in a moving state and will not accumulate, and finally is discharged through the sludge outlet 13.

[0028] Furthermore, third baffles 33 are respectively fixed at both ends of the first baffle 31. A gap is left between each third baffle 33 and the end of the tank body 10 on the same side. Notches 331 and windows 332 for communicating both sides of the first baffle 31 are respectively formed on each third baffle 33. Sewage flows at both ends of the third baffle 33 through the notches 331 and windows 332. After sewage moves along the axial direction of the tank body 10 on one side of the first baffle 31, it flows through the window 332 to the gap between the third baffle 33 and the end of the tank body 10 on the same side, and is blocked by the end of the tank body 10 to complete a turn, and then flows back to the other side of the first baffle 31 through the notch 331.

[0029] In one embodiment, the water inlet 11 is opened at one end of one side of the tank body 10, and the installation height of the water inlet 11 is lower than the top height of the third baffle 33 on this side. Therefore, when the sewage flows into the tank body 10, it is blocked by the third baffle 33 on this side. The sewage first flows into the space between the third baffle 33 on this side and the end of the tank body 10, and then flows into the area between the two second baffles 32 through the notch 331 on the third baffle 33 on this side.

[0030] It is easy to think that the notch 331 and the window 332 on the same third baffle 33 are respectively arranged on both sides of the first baffle 31, and the notches 331 and the windows 332 on the two second baffles 32 are arranged on the same side of the first baffle 31. Therefore, in the same flow direction of the water body flow, the notch 331 and the window 332 serve as the inlet and outlet of the water body flow respectively.

[0031] Furthermore, the notch 331 and the window 332 are respectively arranged at the bottom and top positions of the third baffle 33, so that the water body flows from above into the space between the third baffle 33 and the end of the tank body 10, and flows from below into the middle area between the two second baffles 32, prompting the water body to generate a vertical flow while flowing horizontally, improving the water body flow effect and preventing sludge accumulation.

[0032] In one embodiment, the multi-directional circulation sewage treatment device 100 discharges sludge through an air-lift pipe (not shown in the figure), and the air-lift pipe sinks into the water and is connected to the sludge outlet 13. Of course, other devices such as a submersible sewage pump can also be used, and this embodiment is not limited.

[0033] As Figure 2 and 3 shown, a filter tank 14 is arranged on one side of the first baffle 31, and it is connected to the water outlet 12 to discharge the supernatant. Specifically, the filter tank 14 is arranged at a position closer to the upper part inside the tank body 10, and serrated partitions are respectively arranged on both sides of the filter tank 14 to reduce the flow rate of the supernatant flowing into the filter tank 14 per unit time and prevent the filter tank 14 from being submerged. After the supernatant flows into the filter tank 14 through the serrated partitions, it flows out of the tank body 10 through the water outlet 12.

[0034] Preferably, the above filter tanks 14 are arranged on both sides of the first baffle 31, and correspondingly, two water outlets 12 are arranged on the tank body 10 to improve the water outlet speed.

[0035] Furthermore, the two filter tanks 14 are correspondingly arranged at the same positions on both sides of the first baffle 31, and at the same time, a through hole communicating both sides is opened on the first baffle 31, and the two filter tanks 14 are communicated through this through hole.

[0036] To improve the effect of preventing mud from flowing out during water discharge and prevent sludge from flowing into the filter tank 14 and then flowing out, a plurality of inclined mud baffles 15 are respectively arranged below each filter tank 14. When the water body moves upward, the sludge is blocked by the mud baffles 15, and part of the sludge falls after being blocked, thereby improving the water quality flowing out of the tank body 10.

[0037] In one embodiment, the aeration structure 20 includes an aerobic pipe 21 and an intermittent pipe 22 that respectively extend between two second baffles 32. The former is used to perform continuous aerobic aeration on the water body in the tank body 10, and the latter performs intermittent aeration. The aeration operation can inject sufficient oxygen into the water body, ensure the biological reaction, improve the sewage treatment effect, and prevent sludge deposition. It is easy to think that control valves are arranged on the aerobic pipe 21 and the intermittent pipe 22 to control the on-off of the pipes.

[0038] Preferably, the aerobic pipe 21 is provided with a plurality of air outlets extending to the bottom inside the tank body 10 to increase the aeration points in the water body, improve the sewage treatment effect, and prevent sludge accumulation. For example, air outlets can be arranged in the space between every two third baffles 33.

[0039] In one embodiment, an aerator 221 is arranged at the bottom of the intermittent pipe 22 to increase the aeration area.

[0040] As Figure 1 shown, the main body of the tank body 10 is a horizontally lying cylinder, and a box-shaped control part 16 protrudes therefrom. The sewage flows inside the cylindrical part of the tank body 10. For the convenience of operation, part of the aerobic pipe 21 and the intermittent pipe 22 extend into the operation part 16, and the control valves on the pipes are arranged in the operation part 16. The top of the operation part 16 can be opened, and the staff can open the top of the operation part 16 to operate the valves on the aerobic pipe 21 and the intermittent pipe 22. Correspondingly, the water inlet 11, the water outlet 12, the sludge outlet 13, etc. are all arranged on the operation part 16.

[0041] Preferably, a support base 17 is further arranged at the bottom of the tank body 10 to facilitate the fixation of the multi-directional circulation sewage treatment device at a predetermined position. Since the built-in support base 17 is used as a support, there is no need to configure an additional support structure for it. At the same time, the overall volume of the multi-directional circulation sewage treatment device 100 can be set according to needs (such as the local sewage volume, the spatial information of the placement location, etc.), and this embodiment does not limit.

[0042] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
