[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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.

[0025] As Figure 1 shown, an environment-friendly drainage device for buildings includes: a coarse filtration mechanism 1, and building wastewater first passes through the coarse filtration mechanism 1; a shunt pipe 2, the main pipe 21 of the shunt pipe 2 is communicated with the coarse filtration mechanism 1; a sedimentation tank 3, the branch pipe 22 of the shunt pipe 2 is communicated with the sedimentation tank 3, and an equipment platform 31 is provided at the top of the sedimentation tank 3; a sedimentation mechanism 4, the sedimentation mechanism 4 is arranged in the sedimentation tank 3, and the sedimentation mechanism 4 includes a rotatable sedimentation tray 41 and a scraper 42 for cleaning the sedimentation tray 41; a shunt plate 5, the shunt plate 5 is rotatably connected to the front end of the sedimentation mechanism 4; a purification mechanism 6, the purification mechanism 6 is arranged in front of the shunt plate 5; and an electronic descaling instrument 7, the electronic descaling instrument 7 is communicated with the water outlet pipe of the sedimentation tank 3.

[0026] The coarse filtration mechanism 1 includes a water tank 11 and a grille plate 12. The grille plate 12 is L-shaped, and a slideway is provided on the inner wall of the water tank 11. The grille plate 12 is slidably connected to the slideway. An inlet is provided at the top of the water tank 11, and the grille plate 12 surrounds the inlet. When building sewage enters the water tank 11, it first passes through the grille plate 12, and the grille plate 12 intercepts large pieces of garbage in the building sewage for preliminary filtration. When the garbage intercepted by the grille plate 12 is relatively large, the grille plate 12 is lifted upward along the slideway to clean the garbage on the grille plate 12.

[0027] The sewage flowing out of the water tank 11 enters the shunt pipe 2. The shunt pipe 2 is provided with two branch pipes 22 in total. The branch pipes 22 are provided with solenoid valves 23. The solenoid valves 23 control the water flow paths of the branch pipes 22. The two branch pipes 22 are respectively connected to different sedimentation mechanisms 4.

[0028] As Figure 2 shown, there are two groups of sedimentation mechanisms 4 in total. The two sedimentation mechanisms 4 are separated by a partition plate 34. The sedimentation mechanism 4 further includes a winding shaft 43, a first motor 44, a threaded rod 45, a limiting track 46, a second motor 47 and a water baffle 48.

[0029] A groove is provided in the middle of the sedimentation plate 41. The water in the branch pipe 22 enters above the sedimentation plate 41 and stands still. The sediment settles into the sedimentation plate 41 under the action of gravity. A baffle is provided at the front end of the sedimentation plate 41 to prevent the settled sediment from being washed away by the water flow.

[0030] The bottom of the sedimentation plate 41 is arranged on a slope. The end of the slope close to the branch pipe 22 is higher than the end far from the branch pipe 22. One end of the sedimentation plate 41 is rotatably connected to one end of the sedimentation tank 3 close to the branch pipe 22. The winding shaft 43 is arranged on the equipment platform 31. The first motor 44 drives the winding shaft 43. A traction wire is provided on the winding shaft 43. The first motor 44 drives the winding shaft 43 to wind and unwind the traction wire. The traction wire is connected to the other end of the sedimentation plate 41. After the sediment in the sedimentation plate 41 is settled, the water is discharged forward, and then the traction rope is received to make the sedimentation plate 41 rotate upward, facilitating the cleaning of the sediment in the sedimentation plate 41.

[0031] Under the pulling of the traction rope, the sedimentation plate 41 rotates to a position flush with the scraping plate 42. One end of the threaded rod 45 is fixedly connected to the second motor 47. The other end of the threaded rod 45 is rotatably connected to the partition plate 34. The scraping plate 42 is screwed on the threaded rod 45. Both sides of the scraping plate 42 are slidably connected to the limiting track 46. The second motor 47 is started to drive the threaded rod 45 to rotate, further causing the scraping plate 42 to move along the direction of the threaded rod 45. The limiting track 46 prevents the scraping plate 42 from rotating. The scraping plate 42 pushes and scrapes the sediment in the sedimentation plate 41 during the movement.

[0032] Discharge ports 32 are provided on both sides of the sedimentation tank 3. A garbage pool 33 is provided outside the discharge ports 32. The water baffle 48 is fixedly connected to the sedimentation plate 41. When the sedimentation plate 41 is at the bottom, the water baffle 48 blocks the discharge ports 32. When the water baffle 48 blocks the discharge ports 32, the water in the sediment cannot flow out from the discharge ports 32. When the sedimentation plate 41 rotates upward, the water baffle 48 also rotates together. At this time, the discharge ports 32 are communicated with the outside. The discharge ports 32 and the bottom of the scraping plate 42 are at the same height. The movement of the scraping plate 42 causes the sediment in the sedimentation plate 41 to flow out from the discharge ports 32 and enter the garbage pool 33.

[0033] The flow dividing plate 5 controls the water storage and discharge conditions of the sedimentation mechanism 4. As Figure 3As shown, the flow splitter plate 5 is L-shaped. The length of one side of the flow splitter plate 5 is equal to the distance between the partition plate 34 and the sedimentation tank 3. A third motor 51 is provided at the top of the flow splitter plate 5. The third motor 51 controls the rotation of the flow splitter plate 5. When one end of the flow splitter plate 5 is in contact with the side wall of the sedimentation tank 3, the sedimentation mechanism 4 on the contacting side is in the state of storing water for sedimentation, and the other side is in the state of discharging water. The solenoid valve 23 in the state of storing water for sedimentation is opened to allow sewage to enter this side. After the sedimentation of the sediment is completed, the flow splitter plate 5 is rotated to allow the clear water on the upper side to enter the purification mechanism 6, and then the sediment on the sedimentation plate 41 is cleaned. At the same time, the sedimentation mechanism 4 on the other side enters the state of storing water for sedimentation, thereby ensuring that there is always sewage flowing for treatment and improving the use efficiency of other treatment mechanisms.

[0034] As Figure 4 shown, the purification mechanism 6 includes a push plate 61, a telescopic rod 62 and a filter plate 63. The push plate 61 is L-shaped. The bottom of the push plate 61 is perpendicular to the bottom surface of the sedimentation tank 3, and the top of the push plate 61 is parallel to the top surface of the sedimentation tank 3. The top of the push plate 61 is slidably connected to the top of the sedimentation tank 3. The telescopic rod 62 is provided on the equipment platform 31, and the extended end of the telescopic rod 62 is connected to the push plate 61. The push plate 61 is driven to move back and forth along the direction of the sedimentation tank 3 by the telescopic movement of the telescopic rod 62. The filter plate 63 is provided in front of the push plate 61. A one-way door 611 is provided inside the push plate 61. The one-way door 611 can only open towards the filter plate 63. After the water in the sedimentation mechanism 4 is discharged, it enters between the push plate 61 and the filter plate 63 through the one-way door 611. Then the push plate 61 moves forward to squeeze the sewage through the filter plate 63, and the filter plate 63 cleans the impurities in the filtered water. After each discharge of water from the sedimentation mechanism 4, the push plate 61 extends and retracts several times successively.

[0035] The water flowing out from the filter plate 63 flows through the electronic descaling device 7, making the outflowing water not easy to form scale.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
