[0023] like Figure 1-4 As shown, the filtration device for removing impurities from polyaluminum chloride liquid in this embodiment includes a housing 1. An inlet pipe 2 is connected to the left end of the upper surface of the housing 1. A filtration mechanism is installed above the inlet pipe 2. The polyaluminum chloride liquid requiring impurity removal flows through the filtration mechanism into the inlet pipe 2, thus entering the housing 1. A moving mechanism connected to the upper surface of the housing 1 is installed on the right side of the inlet pipe 2. This moving mechanism controls the movement of the filtration mechanism, allowing it to deviate from the inlet pipe 2 for easier discharge of filtered impurities. Multiple mounting plates 13 are connected inside the housing 1, and adjacent to each other... The mounting plates 13 are fixedly connected by rods. An activated carbon layer is filled between adjacent mounting plates 13 to adsorb and filter organic impurities in the polyaluminum chloride liquid. A sedimentation mechanism is provided on the right side of the mounting plate 13 to precipitate heavy metal impurities in the polyaluminum chloride liquid. A second filter screen 14 is provided on the right side of the sedimentation mechanism, and both the upper and lower ends of the second filter screen 14 are connected to the inner wall of the box 1. The second filter screen 14 can filter the precipitated heavy metal impurities when the liquid is discharged. A drain pipe 18 is connected to the bottom of the right end surface of the box 1.

[0024] Specifically, the filtration mechanism includes a first outer shell 3, a liquid inlet 4, an arc-shaped plate 5, a first filter screen 6, and a through hole 7. The first outer shell 3 is located above the liquid inlet pipe 2, and an opening is provided on the lower surface of the first outer shell 3. The liquid inlet 4 is provided on the upper surface of the first outer shell 3. An arc-shaped plate 5 is attached to the inner wall of the first outer shell 3. Multiple first filter screens 6 are arranged at equal intervals inside the arc-shaped plate 5, and a through hole 7 is provided in the middle position of the lower surface of the arc-shaped plate 5. Polyaluminum chloride liquid enters the interior of the first outer shell 3 through the liquid inlet 4. At this time, it is filtered by the first filter screen 6 to remove particulate impurities. After filtration, the liquid flows out through the through hole 7 and enters the interior of the liquid inlet pipe 2. When it is necessary to remove the impurities filtered out inside, by connecting the motor output end of the front surface of the first outer shell 3 to the first filter screen 6 in the middle position and controlling it to rotate together with the arc-shaped plate 5, the impurities can be poured out through the bottom opening of the first outer shell 3. Three first filter screens 6 are arranged sequentially from top to bottom on the arc-shaped plate 5, and their filter hole diameters decrease sequentially.

[0025] Furthermore, the moving mechanism includes a connecting rod 8, a connecting block 9, a lead screw 10, and a guide rod 11. The connecting rod 8 is connected to the right end surface of the first housing 3, and the bottom end of the connecting rod 8 is connected to the connecting block 9. The lead screw 10 and the guide rod 11 are respectively inserted into the front and rear ends of the connecting block 9. By controlling the rotation of the lead screw 10 by the motor installed on the upper surface of the housing 1, the connecting block 9 can be made to slide to the left, thereby causing the first housing 3 to deviate from the liquid inlet pipe 2, which facilitates the discharge of internal impurities.

[0026] Furthermore, a collection box 12 is provided on the lower left side of the first outer shell 3. The right end surface of the collection box 12 is connected to the box body 1, and a door 19 is installed on the front end surface of the box body 1. The collection box 12 is used to collect impurities discharged from the inside of the first outer shell 3. By opening the door 19, it is convenient to replace and repair the internal structure of the box body 1.

[0027] Furthermore, the sedimentation mechanism includes a stirring block 15 and a liquid outlet 17. The stirring block 15 is connected to the inner wall of the rear end of the tank 1. The outer side of the stirring block 15 is provided with a liquid outlet 17, which is also opened on the inner wall of the rear end of the tank 1. The liquid outlet 17 discharges a solution used to adjust and control the internal pH of the polyaluminum chloride liquid. By rotating the stirring block 15, the solution is ensured to be fully mixed with the polyaluminum chloride liquid.

[0028] Furthermore, multiple outlets 17 are evenly arranged on the inner wall of the rear end of the housing 1. The rear ends of the multiple outlets 17 are all connected to the second outer shell 16. Different outlets 17 are used to discharge water, alkaline solution and acid solution respectively. The interior of the second outer shell 16 is divided into three spaces, which are respectively filled with different liquids.

[0029] Furthermore, the upper surfaces of multiple mounting plates 13 are tightly fitted to the top inner wall of the housing 1, and the bottom ends of the mounting plates 13 are snapped into the housing 1, which facilitates the disassembly and replacement of the mounting plates 13.

[0030] The method of use in this embodiment is as follows: The polyaluminum chloride liquid that needs to be purified flows into the inlet pipe 2 through the filtration mechanism and then enters the tank 1. During this process, the liquid is filtered by the first filter screen 6 to remove particulate impurities. After the liquid enters the tank 1, it comes into contact with the activated carbon layer on the mounting plate 13 to remove internal organic impurities. Then, water, alkaline solution or acid solution is added through the outlet 17 to adjust the pH of the liquid, so that heavy metal impurities precipitate. Finally, the liquid is filtered and discharged through the second filter screen 14. When it is necessary to clean the inside of the first outer shell 3, it is pushed to the top of the collection box 12 by the moving mechanism. Then, by rotating the control arc plate 5, the impurities can be poured out through the bottom opening of the first outer shell 3.

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are 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.
