Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, as Figures 1-7As shown in the figure, a sewage treatment device includes a water storage tank 1 and a sedimentation tank 12. The output end of the water storage tank 1 is communicated with one end of a water pipe 3, and the other end of the water pipe 3 is communicated with the input end of a power box 2. A valve 23 is communicated and arranged on the water pipe 3. The output end of the power box 2 is communicated with one end of a first stirring pipe 8, and the other end of the first stirring pipe 8 is communicated with a liquid inlet 241 at one end of a pressurizing pipe 24. The other end of the pressurizing pipe 24, i.e., a liquid outlet 242, is communicated with one end of a second stirring pipe 13. A plurality of spiral pipes 14 are communicated and arranged on the second stirring pipe 13. The other end of the second stirring pipe 13 is communicated with a tail pipe 17. A plurality of water outlet pipes 18 are communicated and arranged on the tail pipe 17. One end of each water outlet pipe 18 is communicated with a U-shaped pipe 19. The tail pipe 17 is arranged above the sedimentation tank 12 in a matching manner. A mixing mechanism for facilitating the uniform mixing of sewage and chemicals is arranged inside the first stirring pipe 8. Through the mixing mechanism, the sewage and chemicals inside the first stirring pipe 8 can be uniformly mixed;

[0026] The mixing mechanism includes a crankshaft 10. Rotating shafts at both ends of the crankshaft 10 are rotatably provided with support plates 9, and the support plates 9 are fixedly arranged on the first stirring pipe 8. A plurality of lifting plates 11 are rotatably arranged on the crankshaft 10. The lifting plates 11 are slidably arranged in rectangular through holes on the first stirring pipe 8. The two lifting plates 11 are always at different heights. A driving component for facilitating the rotation of the crankshaft 10 is arranged on the rotating shaft at one end of the crankshaft 10. During use, the driving component drives the crankshaft 10 to rotate. When the crankshaft 10 rotates, it drives a plurality of lifting plates 11 to alternately intercept and then release the sewage. When the lifting plates 11 strike the sewage, a water hammer effect will be generated. Under the action of the water hammer effect, the intercepted water will vibrate, thereby being able to shake the chemicals and sewage in the water, and thus achieving the technical effect of mixing and stirring.

[0027] The driving component includes a horizontal water tank plate 4. A water tank is arranged at the upper end of the horizontal water tank plate 4. A horizontal shaft 5 is fixedly arranged on the horizontal water tank plate 4. The horizontal shaft 5 is rotatably arranged in an installation hole inside the power box 2. A water retaining plate 6 is fixedly arranged at the bottom end of the water tank. The cross-section of the water retaining plate 6 is an isosceles triangle. The top end of the water retaining plate 6 is arranged in the water pipe 3 in a matching manner. The water retaining plate 6 divides the water tank at the upper end of the horizontal water tank plate 4 into a left tank 401 and a right tank 402. A rocker 7 is fixedly arranged on one end of the horizontal shaft 5. One end of the rocker 7 is hinged with a transmission disc 25, and the transmission disc 25 is fixedly arranged on the rotating shaft at one end of the crankshaft 10. During use, when sewage enters the power box 2 through the water pipe 3, the sewage falls into the left tank 401 or the right tank 402. When the left tank 401 or the right tank 402 is filled with sewage, the horizontal water tank plate 4 tilts towards one end. Subsequently, the horizontal water tank plate 4 drives the rocker 7 to rotate through the horizontal shaft 5. When the rocker 7 rotates, it drives the crankshaft 10 to rotate through the transmission disc 25.

[0028] A liquid throwing plate 243 is fixedly arranged inside the pressure increasing pipe 24. The liquid throwing plate 243 is inclined relative to the liquid inlet 241. During use, sewage enters the pressure increasing pipe 24 through the liquid inlet 241. Since the liquid throwing plate 243 is inclined relative to the liquid inlet 241, there is an included angle between the liquid throwing plate 243 and the liquid inlet 241. The liquid throwing plate 243 can throw the sewage upward. After being thrown, the sewage will freely fall to the bottom of the pressure increasing pipe 24, and under the action of gravity, the pressure and flow rate of the liquid can be increased.

[0029] The spiral pipe 14 is in a ring shape. A plurality of stirring rods 15 are fixedly arranged inside the spiral pipe 14. The plurality of stirring rods 15 are evenly arranged on the inner side of the spiral pipe 14. A top bead 16 is fixedly arranged at one end of the stirring rod 15. During use, when sewage flows into the spiral pipe 14, the stirring rods 15 and the top beads 16 can stir the sewage and chemical substances, facilitating the uniform mixing of the sewage and the chemical substances.

[0030] The U-shaped pipe 19 is in a U shape. Water outlets are arranged at both ends of the U-shaped pipe 19. The upper end of the sedimentation tank 12 is open. During use, it is convenient to prevent the liquid in the sedimentation tank 12 from becoming turbid due to the impact of the tail pipe 17 discharging water into the sedimentation tank 12.

[0031] A silt discharge door 20 is rotatably arranged at one end of the tail pipe 17. A threaded hole is arranged at the upper end of the silt discharge door 20. A limiting hole is arranged at the position corresponding to the threaded hole at the upper end of the tail pipe 17. A bolt 21 is fitted in the threaded hole. During use, it is convenient to clean the silt or sediment accumulated inside the tail pipe 17.

[0032] One side of the water pipe 3 is communicated with a feeding hopper 22. During use, it is convenient to add chemical substances into the power box 2 through the feeding hopper 22 when treating sewage.

[0033] The above embodiments disclose a sewage treatment device. When sewage needs to be treated, the feeding hopper 22 is opened, and the sewage enters the interior of the power box 2 through the water pipe 3. When the sewage enters the interior of the power box 2, it falls into the left tank 401 or the right tank 402. When the left tank 401 or the right tank 402 is filled with sewage, the horizontal water tank plate 4 tilts towards one end. Subsequently, the horizontal water tank plate 4 drives the rocker 7 to rotate through the horizontal shaft 5. When the rocker 7 rotates, it drives the crankshaft 10 to rotate through the transmission disc 25. When the crankshaft 10 rotates, it drives a plurality of lifting plates 11 to alternately intercept and then release the sewage. When the lifting plates 11 strike the sewage, a water hammer effect will be generated. Under the action of the water hammer effect, the intercepted water will vibrate, and thus the chemical substances and sewage in the water can be shaken evenly, thereby achieving the technical effect of mixing and stirring. Subsequently, the sewage enters the interior of the pressure increasing pipe 24, and at the same time, chemical substances are added into the power box 2 through the feeding hopper 22. Since the liquid throwing plate 243 is inclined relative to the liquid inlet 241, there is an included angle between the liquid throwing plate 243 and the liquid inlet 241. The liquid throwing plate 243 can throw the sewage upward, and after being thrown, the sewage will freely fall to the bottom of the pressure increasing pipe 24. Under the action of gravity, the pressure and flow rate of the liquid can be increased. The sewage enters the interior of the tail pipe 17 after passing through a plurality of spiral pipes 14, and the tail pipe 17 discharges the sewage into the sedimentation tank 12 through a plurality of water outlet pipes 18 and U-shaped pipes 19 for sedimentation.

[0034] As described above, the above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
