[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A device for removing heavy metal ions from polluted water comprises a heavy metal ion removal device body 1, the heavy metal ion removal device body 1 comprises three reagent mixer bodies 2 and a sedimentation tank 3, the three reagent mixer bodies 2 are placed in sequence at equal distances, and a sedimentation tank 3 is arranged on one side of the three reagent mixer bodies 2, a first cavity 3-1, a second cavity 3-2, and a third cavity 3-3 are arranged in sequence at equal distances on the top of the sedimentation tank 3, and a mixer is arranged on the top of the first cavity 3-1, the second cavity 3-2, and the third cavity 3-3 Structure 31, and sedimentation bins 32 are installed at the bottom of the sedimentation tank 3 and below the corresponding first cavity 3-1, second cavity 3-2, and third cavity 3-3, and the three chemical mixer bodies 2 are all existing structures and technologies, and chemical agents and sewage that can remove heavy metal ions are respectively placed in the three chemical mixer bodies 2, and the three chemical mixer bodies 2 inject the mixed liquid after stirring into the sedimentation tank 3, wherein the heavy metal ions inside the sewage are preliminarily removed by the three chemical mixer bodies 2.

[0023] Through holes are provided in the sedimentation tank 3 below the first cavity 3-1 and the second cavity 3-2 and below the second cavity 3-2 and the third cavity 3-3, and blocking and filtering mechanisms are provided in the through holes.

[0024] At the same time, the stirring mechanism 31 includes a fixed placement plate 311, which is placed on the top of the sedimentation tank 3, and a driving motor 313 is vertically arranged in the middle of the top of the fixed placement plate 311. It is worth mentioning that the driving motor 313 is an existing structure and technology, so this technical solution will not be elaborated.

[0025] In addition, the output end of the driving motor 313 is connected to the stirring shaft 314 through the fixed placement plate 311, and the outer wall of the stirring shaft 314 is equidistantly installed with stirring rods, and the top of the fixed placement plate 311 is symmetrically installed with feed ports 312 on both sides of the driving motor 313. The feed ports 312 are used to facilitate the injection of the precipitant into the sedimentation tank 3, and the precipitant is a precipitant that can remove heavy metal ions. At the same time, the precipitant is a prior art, so it is not elaborated in detail.

[0026] In addition, the blocking and filtering mechanism includes a limiting baffle 34 and a filter plate 33. The filter plate 33 is slidably installed in the middle of the through hole, and connecting rods 331 are installed on both sides of the top of the filter plate 33. One end of the connecting rod 331 passes through the sedimentation tank 3 and is connected to the limiting plate 332. The bottom of the through hole is located on both sides of the filter plate 33 with inclined surfaces. The limiting plate 332 and the connecting rod 331 facilitate the removal and cleaning of the filter plate 33 after it has been used for a period of time.

[0027] At the same time, a slide groove is opened on one side of the filter plate 33 in the sedimentation tank 3, and a slider is slidably installed in the slide groove. The bottom of the slider passes through the slide groove and is connected to the limit baffle 34, and the bottom of the limit baffle 34 is in contact with the inclined surface of the through hole. It is worth mentioning that the limit baffle 34 of the through hole between the first cavity 3-1 and the second cavity 3-2 is located on the side close to the first cavity 3-1, and the limit baffle 34 of the through hole between the second cavity 3-2 and the third cavity 3-3 is located on the side close to the second cavity 3-2.

[0028] In addition, a sewage outlet is installed at the bottom of one side of the sedimentation bin 32, and the sewage outlet is equipped with a sewage valve, and a drainage outlet is installed at the bottom of one side of the third cavity 3-3, and the drainage outlet is equipped with a drainage valve.

[0029] In this embodiment, chemical agents capable of removing heavy metal ions and sewage are placed in three chemical mixer bodies 2 respectively, and the three chemical mixer bodies 2 inject the mixed liquid after stirring into the sedimentation tank 3, wherein the three chemical mixer bodies 2 perform preliminary removal of heavy metal ions in the sewage.

[0030] Next, the precipitant is injected into the first cavity 3-1 of the sedimentation bin 32 through the feed port 312, and the precipitant and its sewage are stirred by the stirring mechanism 31, thereby helping to accelerate the reaction between the heavy metal ions and the precipitant and improving the efficiency of removing heavy metal ions in the sewage. After the stirring is completed, the stirring mechanism 31 is stationary for a period of time, and then the electric telescopic rod 341 is closed, thereby driving the limit baffle 34 to move into the chute and causing the water in the first cavity 3-1 of the sedimentation bin 32, after the heavy metal ions are initially removed, to flow into the second cavity 3-2 of the sedimentation bin 32. During the flow, the filter plate 33 filters the larger precipitates attached to it. At the same time, during the static process, the precipitate produced by the reaction of the precipitant in the first cavity 3-1 of the sedimentation bin 32 with the heavy metal ions in the sewage is located in the corresponding sedimentation bin 32.

[0031] Then, the precipitant is injected into the second cavity 3-2 of the sedimentation bin 32 through the feed port 312, and the precipitant and its sewage are stirred by the stirring mechanism 31, thereby helping to accelerate the reaction between the heavy metal ions and the precipitant and improving the efficiency of removing heavy metal ions in the sewage. After the stirring is completed, the stirring mechanism 31 is stationary for a period of time, and then the electric telescopic rod 341 is closed, thereby driving the limit baffle 34 to move into the slide chute and causing the water in the third cavity 3-3 of the sedimentation bin 32, after the heavy metal ions are initially removed, to flow into the second cavity 3-2 of the sedimentation bin 32. During the flow, the filter plate 33 filters the larger precipitates attached to it. At the same time, during the static process, the precipitate produced by the reaction of the precipitant in the second cavity 3-2 of the sedimentation bin 32 with the heavy metal ions in its sewage is located in the corresponding sedimentation bin 32.

[0032] Then, the precipitant is injected into the third cavity 3-3 of the sedimentation bin 32 through the feed port 312, and the injected precipitant and its sewage are stirred by the stirring mechanism 31, thereby helping to accelerate the reaction between the heavy metal ions and the precipitant and improving the efficiency of removing heavy metal ions in the sewage. After the stirring mechanism 31 completes the stirring, it remains stationary for a period of time, and then the water after the heavy metal ions are effectively removed is discharged through the drain port 35. At the same time, during the stationary process, the precipitate produced by the reaction of the precipitant in the third cavity 3-3 of the sedimentation bin 32 with the heavy metal ions in the sewage is located in the corresponding sedimentation bin 32.

[0033] Furthermore, the precipitate produced by the reaction of the precipitant settled in the precipitation bin 32 with the heavy metal ions in the sewage is discharged through the sewage outlet 35 .

[0034] In the utility model, the heavy metal ions in the sewage are removed step by step through the first cavity 3-1, the second cavity 3-2 and the third cavity 3-3 of the sedimentation bin 32, so that the heavy metal ions in the sewage can be effectively removed, and in the process of removing the heavy metal ions, the input precipitant and the sewage are stirred by the stirring mechanism 31, thereby helping to accelerate the reaction between the heavy metal ions and the precipitant and improving the efficiency of removing the heavy metal ions in the sewage.
