[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Please refer to the appendix. Figures 1-4The present invention provides a sedimentation device for the recycling and treatment of construction wastewater, comprising a sedimentation tank 1, a wastewater inlet pipe 2 fixedly connected to the bottom side of the sedimentation tank 1, a sand discharge pipe 3 fixedly connected to the bottom of the sedimentation tank 1, a first shut-off valve 4 fixedly fixed to the body of the sand discharge pipe 3 for discharging the sedimented sludge, a drain pipe 5 fixedly connected to the lower side of the sedimentation tank 1, a second shut-off valve 6 fixedly fixed to the body of the drain pipe 5 for discharging the treated wastewater, a glass window 7 fixedly fixed to the lower front end of the sedimentation tank 1, the glass window 7 being located below the horizontal plane of the drain pipe 5 for convenient observation by operators of the stratification of the sediment at the bottom of the sedimentation tank and the wastewater at the top, a stirring assembly fixedly fixed inside the sedimentation tank 1, a scraping assembly and a first anti-clogging assembly fixedly fixed on the stirring assembly, a pre-filtration assembly for removing stones from the construction wastewater fixedly fixed to the side of the sedimentation tank 1, the pre-filtration assembly being fixedly connected to the wastewater inlet pipe 2, a second anti-clogging assembly fixedly fixed on the pre-filtration assembly, and a suspended solids treatment assembly fixedly fixed on the sedimentation tank 1;

[0028] The mixing assembly includes a motor bracket 8, the bottom of which is fixed to the middle of the top of the settling tank 1. A mixing motor 9 is vertically fixed on the motor bracket 8. A connecting shaft 10 is fixed to the bottom of the output shaft of the mixing motor 9. The bottom of the connecting shaft 10 vertically passes through the center of the top of the settling tank 1, and a mixing paddle 11 is fixed to the bottom of the connecting shaft 10. Specifically, when the mixing motor 9 is running, it can drive the mixing paddle 11 to rotate inside the settling tank 1 through the connecting shaft 10.

[0029] The scraping assembly includes a connecting plate 12, which is symmetrically fixed to both ends of the mixing paddle 11. Rubber scrapers 13 are fixed to the surface of the connecting plate 12, and the surfaces of the rubber scrapers 13 abut against the inner surface of the sedimentation tank 1. Specifically, when the mixing motor 9 runs and drives the mixing paddle 11 to rotate inside the sedimentation tank 1, the connecting plate 12 can drive the rubber scrapers 13 to rotate synchronously, thereby enabling the rubber scrapers 13 to perform scraping operations on the inner surface of the sedimentation tank 1, thus effectively preventing the silt in the construction sewage from adhering to the inner surface of the sedimentation tank 1.

[0030] The first anti-clogging component includes a vertically arranged threaded conveyor rod 14. The top end of the threaded conveyor rod 14 is fixed to the bottom end of the agitator 11, and the bottom end of the threaded conveyor rod 14 extends to the inside of the sand discharge pipe 3. Specifically, when the agitator motor 9 runs and drives the agitator 11 to rotate inside the sand settling tank 1, it can also drive the threaded conveyor rod 14 to rotate synchronously. Therefore, when the operator opens the first shut-off valve 4 and discharges the settled mud and sand through the sand discharge pipe 3, the agitator motor 9 can be controlled to run, so that the threaded conveyor rod 14 can rotate. The rotating threaded conveyor rod 14 can apply a downward pushing force to the mud and sand settled at the bottom inside the sand settling tank 1, thereby effectively preventing the settled mud and sand from clogging when discharged.

[0031] The pre-filtration assembly includes a bracket 15, which is fixed to the side of the settling tank 1. A pretreatment tank 16 is fixedly fixed through the bracket 15. The end of the sewage inlet pipe 2 is fixedly connected to the upper side of the pretreatment tank 16. A filter plate 17 is fixedly fixed inside the upper part of the pretreatment tank 16. Several filter holes 18 are evenly opened on the filter plate 17. A sewage filling pipe 19 is fixedly connected to the side of the pretreatment tank 16. It should be noted that the sewage filling pipe 19 is connected to a sewage pump (not shown in the figure) through a pipe. Specifically, the construction sewage can first be pumped into the pretreatment tank 16 through the sewage filling pipe 19, and then filtered through the several filter holes 18 on the filter plate 17 to remove stones before entering the settling tank 1 through the sewage inlet pipe 2 for settling treatment. That is, the settling tank has the function of settling and recycling construction sewage, and can also effectively pre-filter large impurities such as stones in the construction sewage.

[0032] The pre-filtration assembly also includes a slag discharge pipe 20. The top end of the slag discharge pipe 20 is fixedly connected to the bottom of the pretreatment tank 16. A third shut-off valve 21 is fixed to the body of the slag discharge pipe 20. Specifically, when the third shut-off valve 21 is opened, large impurities such as stones that have been filtered out can be discharged through the slag discharge pipe 20.

[0033] The second anti-clogging component includes a vertically arranged electric push rod 22. The bottom end of the electric push rod 22 is fixed at the center of the top of the pretreatment tank 16. A pressure plate 23 is fixed at the bottom end of the output shaft of the electric push rod 22. Several unblocking short rods 24 are evenly fixed at the bottom of the pressure plate 23. The several unblocking short rods 24 correspond one-to-one with several filter holes 18. The unblocking short rods 24 are located directly above the corresponding filter holes 18 and can pass through the corresponding filter holes 18. Specifically, when the electric push rod 22 is running, it can drive the pressure plate 23 to rise and fall, thereby driving the several unblocking short rods 24 to rise and fall. The unblocking short rods 24 can then move down to unblock the corresponding filter holes 18, thus effectively preventing the filter holes 18 from becoming clogged.

[0034] The second anti-clogging component also includes a vertically installed unblocking rod 25. The top of the unblocking rod 25 is fixed at the bottom center of the pressure plate 23, and the bottom of the unblocking rod 25 passes through the center of the filter plate 17 and extends to the lower part of the pretreatment tank 16. Specifically, when the electric push rod 22 drives the pressure plate 23 to rise and fall, it can also drive the unblocking rod 25 to rise and fall synchronously. Therefore, when the third shut-off valve 21 is opened, when the filtered stones and other large impurities are discharged through the slag discharge pipe 20, the operator can control the unblocking rod 25 to rise and fall through the electric push rod 22, thereby applying a downward pushing force to the stones and other impurities, which can effectively prevent blockage when the stones and other impurities are discharged.

[0035] The suspended solids treatment assembly includes a flocculant storage tank 26, the bottom of which is fixed to one side of the top of the settling tank 1. A flocculant feed pipe 27 is fixedly connected to the bottom of the flocculant storage tank 26. A fourth shut-off valve 28 is fixedly attached to the body of the flocculant feed pipe 27. A flocculant delivery bend 29 is fixedly connected to the bottom of the flocculant feed pipe 27. The bottom of the flocculant delivery bend 29 penetrates the top of the settling tank 1 and is fixedly connected to an annular distributor 30. An agitator 11 passes vertically through the annular distributor 30. The bottom of the annular diverter 30 is evenly provided with several flocculant addition ports 31. Specifically, when the fourth shut-off valve 28 is opened, the flocculant stored in the flocculant storage tank 26 can be transported to the annular diverter 30 through the flocculant feeding pipe 27 and the flocculant conveying bend 29, and then evenly added to the construction wastewater in the sedimentation tank 1 through several flocculant addition ports 31. With the stirring action of the agitator 11, the suspended solids in the construction wastewater can be effectively precipitated, thereby effectively improving the recycling and treatment effect of construction wastewater.

[0036] It should be noted that this utility model is electrically connected to an external main controller and 220V AC mains power, and the main controller can be an existing technology device such as a computer for control.

[0037] The usage process of this utility model is as follows: Construction sewage can first be pumped into the pretreatment tank 16 through the sewage filling pipe 19, and then filtered through several filter holes 18 on the filter plate 17 to remove stones before entering the sedimentation tank 1 through the sewage inlet pipe 2 for sedimentation treatment. When the filter holes 18 are blocked, the operator controls the electric push rod 22 to run. When the electric push rod 22 runs, it can drive the pressure plate 23 to rise and fall, thereby driving several unblocking short rods 24 to rise and fall. The unblocking short rods 24 can be moved down to unblock the corresponding filter holes 18. After the construction sewage has been filtered and pretreated, it enters the sedimentation tank 1. The operator then opens the third shut-off valve 21. When the third shut-off valve 21 is opened, the filtered stones and other large impurities can be discharged through the slag discharge pipe 20. The operator can control the unblocking long rod 25 to rise and fall through the electric push rod 22, thereby applying a downward pushing force to the stones and other impurities, which can effectively prevent blockage when the stones and other impurities are discharged.

[0038] After the construction wastewater, which has been filtered to remove large impurities such as stones, is discharged into the settling tank 1 through the wastewater inlet pipe 2, the operator turns on the stirring motor 9 and the fourth shut-off valve 28. When the stirring motor 9 is running, it can drive the stirring paddle 11 to rotate inside the settling tank 1 through the connecting shaft 10. When the fourth shut-off valve 28 is opened, the flocculant stored in the flocculant storage tank 26 can be transported to the annular diverter 30 through the flocculant feeding pipe 27 and the flocculant conveying bend 29. Then, it is evenly added to the construction wastewater in the settling tank 1 through several flocculant addition ports 31. With the stirring action of the stirring paddle 11, the suspended solids in the construction wastewater can be effectively settled, thereby effectively improving the recycling and treatment effect of the construction wastewater. When the stirring motor 9 runs and drives the stirring paddle 11 to rotate inside the settling tank 1, it can drive the rubber scraper 13 to rotate synchronously through the connecting plate 12. This allows the rubber scraper 13 to scrape the inner surface of the settling tank 1, thereby effectively preventing the mud and sand in the construction wastewater from adhering to the inner surface of the settling tank 1.

[0039] After mixing, the operator turns off the mixing motor 9, allowing the construction wastewater mixed with flocculant to settle in the sedimentation tank 1. Under the action of gravity, sedimentation is carried out. After sedimentation, the operator first opens the second shut-off valve 6 to discharge the upper layer of wastewater through the drain pipe 5, and then opens the first shut-off valve 4 and the mixing motor 9 to discharge the sediment through the sand discharge pipe 3. When the mixing motor 9 is running, the threaded conveyor rod 14 can also rotate. The rotating threaded conveyor rod 14 can exert a downward pushing force on the sediment at the bottom of the sedimentation tank 1, thereby effectively preventing the sediment from clogging when it is discharged.

[0040] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
