Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4As shown, an environmental protection device for treating heavy metal wastewater includes an installation tank 1, which is a circular tank. A fixed cylinder 10 is fixedly installed on the bottom side of the installation tank 1, and a sedimentation tank 2 is fixedly installed on the upper end of the fixed cylinder 10. A top cover 18 is snapped onto the upper end of the sedimentation tank 2. A movable filter screen 3 is installed inside the installation tank 1, and a rotating structure that drives a connecting rod 9 to rotate is also provided inside the installation tank 1. A connecting cylinder 4 is fixedly installed on the upper end of the filter screen 3, and a movable cylinder 5 is movably installed on the upper end of the connecting cylinder 4. A driving structure that drives the movable cylinder 5 to move upwards is provided on the upper end of the top cover 18. A groove 19 is provided on the upper side of the sedimentation tank 2. A cleaning structure is provided above the installation tank 1. The connecting cylinder 4 is an outer... The connecting cylinder 5 is a cylindrical shape with a circular inner side and a rectangular inner side. An movable cavity 811 is formed inside the movable cylinder 5, with a cross-section of an inverted "L"-shaped annular cavity. A movable block 812 is fixedly installed at the upper end of the connecting cylinder 4, and the movable block 812 is movably installed inside the movable cavity 811. The movable cylinder 5 rotates above the connecting cylinder 4. When the movable cylinder 5 moves upward, it can drive the connecting cylinder 4 to move upward. The movable block 812 has an inverted "L"-shaped annular cross-section, and rotating cavities 813 are equidistantly formed on its side. Rotating balls 814 are installed inside the rotating cavities 813. When the connecting cylinder 4 rotates, friction occurs between the rotating balls 814 and the movable cylinder 5, thereby reducing friction between the connecting cylinder 4 and the movable cylinder 5. The friction between the cylinders 5 is used when the filter screen 3 is at the bottom of the sedimentation tank 2, and the heavy metal wastewater is inside the sedimentation tank 2. Flocculant is added into the sedimentation tank 2 to cause the heavy metal wastewater inside the sedimentation tank 2 to react. At this time, the connecting cylinder 4 is started to rotate by the rotating structure. The connecting cylinder 4 drives the filter screen 3 inside the sedimentation tank 2 to rotate. The filter screen 3 drives the liquid and flocculant inside the sedimentation tank 2 to mix evenly. When the internal reaction is completed, the flocculent objects will float in the liquid. The driving structure drives the movable cylinder 5 upward, and the movable cylinder 5 drives the connecting cylinder 4 and the filter screen 3 upward. When the filter screen 3 moves upward, it carries the floating flocculent objects upward. The filter screen 3 moves to the groove. At position 19, the rotating structure drives the filter screen 3 to rotate. After the filter screen 3 rotates, the flocculent material on the filter screen 3 moves out through the filter screen 3 to treat the flocculent material. A guide block 20 is fixedly installed on the outside of the fixed cylinder 10. The guide block 20 is a hollow frustum shape. A guide pipe 21 is fixedly installed on the side of the mounting cylinder 1. The flocculent material that is thrown out is discharged through the guide pipe 21. The driving structure includes a guide wheel 7 movably installed on the upper end of the cover 18. A winch 6 is fixedly set on the side of the guide wheel 7 at the upper end of the cover 18. A connecting rod 9 is fixedly installed inside the movable cylinder 5. One end of the rope is fixed to the connecting rod 9 and the other end is fixed to the winch 6. The rope is turned through the guide wheel 7.

[0025] The rotating structure includes a rotating motor 11 fixedly installed inside the fixed cylinder 10 on the bottom side of the installation tank 1. An installation cavity 13 is opened on the bottom side of the sedimentation tank 2. A rotating bearing 14 is rotatably connected inside the installation cavity 13. The output end of the rotating motor 11 is fixedly installed to the lower end of the rotating bearing 14. A rotating rod 12 is fixedly installed to the upper end of the rotating bearing 14. The rotating rod 12 extends upward through the filter screen 3 and into the interior of the connecting cylinder 4. The rotating rod 12 is a rectangular rod adapted to the inner side of the connecting cylinder 4. The rotating motor 11 drives the rotating bearing 14 to rotate, and the rotating bearing 14 drives the rotating rod 12 to rotate. 2 drives the filter screen 3 and the connecting cylinder 4 to rotate. The cleaning structure includes a connecting pipe 15 fixedly installed on the upper end of the installation tank 1. The connecting pipe 15 is a hollow circular pipe. The side of the connecting pipe 15 is provided with liquid outlet chambers 16 at equal intervals corresponding to the inner side of the installation tank 1. A fixed liquid inlet pipe 17 is provided on the outer side of the connecting pipe 15. The liquid inlet pipe 17 is connected to the inside of the connecting pipe 15. The liquid inlet pipe 17 pours water into the inside of the connecting pipe 15. The water inside the connecting pipe 15 flushes the inner wall of the installation tank 1 through the liquid outlet chambers 16. The flocculent falls into the inner bottom of the installation tank 1 to clean the flocculent on the wall of the installation tank 1.

[0026] The working principle of this utility model:

[0027] During use, filter screen 3 is positioned at the bottom of sedimentation tank 2, with heavy metal wastewater inside. Flocculant is added to sedimentation tank 2 to induce a reaction in the wastewater. Simultaneously, a rotating mechanism activates the connecting cylinder 4, which in turn rotates the filter screen 3 inside the sedimentation tank 2. The filter screen 3 causes the liquid and flocculant inside the sedimentation tank 2 to mix evenly. Once the reaction is complete, the flocculated material floats within the liquid. A drive mechanism then moves the movable cylinder 5 upwards, which in turn moves the connecting cylinder 4 and filter screen 3 upwards. As the filter screen 3 moves upwards, it carries the floating flocculated material. When the filter screen 3 reaches the groove 19, the rotating mechanism rotates it, allowing the flocculated material on the filter screen 3 to pass through and be released, thus achieving flocculation. The material is processed. The movable cylinder 5 rotates above the connecting cylinder 4. When the movable cylinder 5 moves upward, it can drive the connecting cylinder 4 to move upward. When the connecting cylinder 4 rotates, it rubs against the movable cylinder 5 through the rotating ball 814, thereby reducing the friction between the connecting cylinder 4 and the movable cylinder 5. The flung-out flocculent is discharged through the guide pipe 21. The rotary motor 11 drives the rotary bearing 14 to rotate, the rotary bearing 14 drives the rotary rod 12 to rotate, and the rotary rod 12 drives the filter screen 3 and the connecting cylinder 4 to rotate. The liquid inlet pipe 17 fills the inside of the connecting pipe 15 with water. The water inside the connecting pipe 15 flushes the inner wall of the installation tank 1 through the liquid outlet chamber 16. The flocculent falls into the bottom of the inside of the installation tank 1 to clean the flocculent on the wall of the installation tank 1. One end of the rope is fixed to the connecting rod 9, and the other end is fixed to the winch 6. The rope is turned by the guide wheel 7.
