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

[0020] Please see Figure 1-4 This utility model provides the following technical solution: a surface water heavy metal detoxification device, including a working plate 1, a working box 2 fixedly installed on both sides inside the working plate 1, a water pump 13 fixedly installed on one side of the top of the working box 2, a first water pipe 12 provided at the output end of the water pump 13, a second motor 4 fixedly installed on one side of the working plate 1, a threaded rod 11 provided at the output end of the second motor 4, a connecting box 16 threadedly connected to the surface of the threaded rod 11, a filter box 21 snapped into both sides inside the connecting box 16, a second handle 20 fixedly installed on both sides of the top of the filter box 21, a second connecting pipe 19 fixedly connected to both sides of the bottom of the connecting box 16, a support plate 5 fixedly installed around the bottom of the working plate 1, a limit frame 8 fixedly installed on the inner wall of the support plate 5, a water tank 7 provided on the inner wall of the limit frame 8, a feed hopper 15 fixedly connected to the top of the water tank 7, and a first handle 6 fixedly installed on one side of the water tank 7.

[0021] In a specific embodiment of this utility model, wastewater containing heavy metals is placed inside the working tank 2, and lime is placed inside the working tank 2 to cause the heavy metal ions in the wastewater to precipitate as insoluble hydroxides, thus detoxifying the wastewater. Then, flocculant is added to the working tank 2 to accelerate sedimentation. The water pump 13 operates to pump the upper layer of clear water inside the working tank 2 through the first water pipe 12 to the filter tank 21. The activated carbon inside the filter tank 21 filters the water to remove residual dissolved heavy metals, organic pollutants, and unsettled fine particles, improving the detoxification quality of the equipment. The filtered water is collected in the water tank 7 through the second connecting pipe 19 and the feed hopper 15. The water pumps 13 on both sides operate to alternate the operation of the two working tanks 2, reducing the waiting time for detoxification. The second motor 4 operates to rotate the threaded rod 11, which moves the connecting box 16 to move and replace the filter tank 21, greatly improving work efficiency.

[0022] In this embodiment: the first motor 3 is set to work, causing the rotating shaft 18 to drive the stirring rod 17 to rotate, so as to stir the inside of the working box 2 evenly, accelerate the reaction speed of sewage, lime and flocculant inside the working box 2, and shorten the reaction time.

[0023] In this embodiment: After the work is completed, the spiral centrifugal pump 9 is used to move the sediment inside the working box 2 out through the bottom of the first connecting pipe 10. The operation is simple and the work difficulty is reduced.

[0024] The working principle and usage process of this utility model are as follows: After installation, wastewater containing heavy metals is placed inside the working tank 2. Lime is then placed inside the working tank 2 to cause the heavy metal ions in the wastewater to precipitate as insoluble hydroxides, thus achieving detoxification. Next, flocculant is added to the working tank 2. The first motor 3 operates, causing the rotating shaft 18 to drive the stirring rod 17 to rotate, uniformly stirring the contents of the working tank 2 and accelerating the sedimentation of the wastewater, lime, and flocculant, thus shortening the reaction time. A water pump 13 on one side operates, pumping the upper layer of clear water from the working tank 2 through the first water pipe 12 to the filter tank 21. The water is filtered by the activated carbon inside the filter tank 21 to remove residual dissolved heavy metals, organic pollutants, and unsettled fine particles, improving the detoxification quality of the equipment. The filtered water is collected through the second connecting pipe 19 and the feed hopper 15. Inside the water tank 7, the second motor 4 rotates the threaded rod 11, moving the connecting box 16 and the filter box 21 for replacement. The operator holds the second handle 20 to pull the used filter box 21 out of the connecting box 16 for cleaning. The water pump 13 on the other side pumps the upper layer of clean water from the working box 2 through the first water pipe 12 into the filter box 21. The activated carbon inside the filter box 21 filters the water, removing residual dissolved heavy metals, organic pollutants, and unsettled fine particles. The filtered water is then collected back into the water tank 7 through the second connecting pipe 19 and the feed hopper 15. The water pumps 13 on both sides work alternately to alternate the operation of the working boxes 2 on both sides, reducing the waiting time for detoxification. All electrical equipment in this device is powered by an external power source, and the motors, electric push rods, etc., in this device are controlled by a PLC controller system.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
