There are multiple groups of handles 7, which are adapted to each other. There are two groups of handles 7, and four groups of fixing blocks 13 and drain pipes 14. The water sample is introduced into the cleaning tank 1. In this process, the filter frame 4 plays a key role. The activated carbon filter plate 6 fixed to the inner side of the filter frame 4 can effectively absorb impurities and odor substances in the water sample, thereby improving the purity of the water sample. At the same time, the card block 5 fixed to one side of the filter frame 4 is adapted to the card slot 8 opened on the top of the cleaning tank 1, so that the filter frame 4 can be firmly installed in the cleaning tank 1. The setting of the handle 7 facilitates the taking and placing operation of the filter frame 4. Inside the cleaning tank 1, after the water sample is initially filtered, it will further flow into the processing barrel 2 below through the funnel 9. The drain port 10 opened on one side of the funnel 9 ensures that the water sample can flow smoothly into the processing barrel 2.

[0021] Reference Figures 2 to 4 The treatment barrel 2 is fixedly connected below the downpipe 14, a medicine-applying port 16 is fixedly connected above the treatment barrel 2, a rotating rod 17 is provided above the treatment barrel 2, a stirring blade 18 is fixedly connected to one side of the rotating rod 17, and the stirring blade 18 is provided in multiple groups. A servo motor 12 is provided inside the motor compartment 11 below the funnel 9, and the motor can be started and shut down through the control panel 19 to control the stirring speed and time of the water sample in the treatment barrel 2. The treatment barrel 2 is one of the core components of the pretreatment device, and the medicine-applying port 16 fixedly connected above it can conveniently add various chemical reagents into the barrel for more in-depth chemical treatment. At the same time, the rotating rod 17 provided above the treatment barrel 2 and the stirring blade 18 fixedly connected to one side thereof can fully stir the water sample under the drive of the servo motor 12 to ensure that the chemical reagent and the water sample can be evenly mixed, thereby improving the pretreatment effect.

[0022] Reference Figure 1 to Figure 2 A control panel 19 is electrically connected to one side of the detection base 3, and the pre-treated water sample will flow into the detection base 3 through the downpipe 14 fixed below the fixed block 13 for subsequent water quality analysis.

[0023] The working principle of the utility model is as follows: first, the water sample is introduced into the cleaning box 1. In this process, the filter frame 4 plays a key role. The activated carbon filter plate 6 fixed to the inner side of the filter frame 4 can effectively absorb impurities and odor substances in the water sample, thereby improving the purity of the water sample. At the same time, the card block 5 fixed to one side of the filter frame 4 and the card slot 8 opened on the top of the cleaning box 1 are adapted to each other, so that the filter frame 4 can be firmly installed in the cleaning box 1. The setting of the handle 7 facilitates the operation of taking and placing the filter frame 4. Inside the cleaning box 1, the water sample will pass through the cleaning box 1 after preliminary filtration. The water sample flows into the treatment barrel 2 below through the funnel 9. The drain port 10 opened on one side of the funnel 9 ensures that the water sample can flow smoothly into the treatment barrel 2 without being blocked. At the same time, a servo motor 12 is provided inside the motor compartment 11 below the funnel 9. The motor can be started and shut down through the control panel 19 to control the stirring speed and time of the water sample in the treatment barrel 2. The treatment barrel 2 is one of the core components of the pretreatment device. The medicine inlet 16 fixed on the top of it can easily add various chemical reagents to the barrel for more in-depth chemical treatment. At the same time, the rotating rod 17 provided on the top of the treatment barrel 2 and the stirring blade 18 fixed on one side can fully stir the water sample under the drive of the servo motor 12 to ensure that the chemical reagent and the water sample can be evenly mixed, thereby improving the pretreatment effect. Finally, the pretreated water sample will flow into the detection base 3 through the drain pipe 14 fixed under the fixed block 13 for subsequent water quality analysis.

[0024] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
