[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Example 1:

[0026] This embodiment addresses the problem that existing processing devices struggle to effectively remove suspended solids, particulate matter, and other impurities, and that it is difficult to properly classify impurities during the processing to reduce waste and environmental pollution.

[0027] Please see Figures 1-5 As shown, this embodiment is a multi-stage waste liquid treatment device based on the acesulfame continuous neutralization process, including a treatment tank 1. A conveying pipe 3 is connected to one side of the top of the treatment tank 1, and a conveying pipe 5 is connected to one side of the bottom of the treatment tank 1. The end of the conveying pipe 5 away from the treatment tank 1 is connected to the treatment tank 2. The bottom of the treatment tank 1 and the treatment tank 2 are respectively provided with a discharge port 4 and a discharge port 9. Valves are provided at the discharge port 4 and the discharge port 9. A feeding port 7 is opened on the upper surface of the treatment tank 2.

[0028] A filter assembly is installed inside the treatment tank 1. The filter assembly includes a filter box 11 located inside the treatment tank 1. The filter box 11 is rotatably connected to the inner wall of the treatment tank 1. The filter assembly uses acesulfame potassium to continuously neutralize suspended solids, particulate matter and other impurities in the waste liquid for preliminary treatment. The through holes on the surface of the filter box 11 perform preliminary filtration of the waste liquid. The filtered waste liquid is transported to the treatment tank 2 through the conveying pipe 25 for further neutralization of acidic substances in the waste liquid.

[0029] A filter assembly 2 is installed on one side of the bottom of the second processing tank 2. The filter assembly 2 includes a processing box 8 connected to the discharge port 2 9. A frame 16 is slidably connected to the inner wall of the processing box 8. A filter screen 19 is embedded in the inner wall of the frame 16. Discharge ports 3 are provided at both ends of the processing box 8. The filtered residue and liquid can be discharged separately through the discharge ports 3. The waste liquid may contain inorganic acids such as sulfuric acid. The inorganic acids are neutralized again according to the composition of different processes to reduce solvent waste and environmental pollution. The recovered solvent can be reused in production or other treatments, and then discharged into the processing box 8 through the discharge port 2 9 on one side of the bottom of the second processing tank 2, so as to achieve reasonable recycling and full utilization.

[0030] The filter box 11 is fixedly connected to two sides with a rotating shaft that passes through the treatment tank 1. A motor 2 10 is fixedly installed on one side of the outer wall of the treatment tank 1. The output end of the motor 2 10 is fixedly connected to the rotating shaft of the filter box 11. When the motor 2 10 is started, the output end of the motor 2 10 drives the rotating shaft of the filter box 11 to rotate, thereby causing the filter box 11 inside the treatment tank 1 to rotate and flip the state of the filter box 11, so as to facilitate the washing of suspended solids, particulate matter and other impurities in the filter box 11. The control valve located at the bottom of the discharge port 4 is opened to facilitate the washing of the residue on the filter box 11 and the centralized collection and discharge.

[0031] Two symmetrically arranged limiting rods 20 are fixedly connected to the inner wall of the treatment tank 8. The two limiting rods 20 pass through the frame 16 and are slidably connected to the frame 16. By setting the limiting rods 20, the frame 16 is limited, ensuring that the frame 16 can move stably in the horizontal direction. The frame 16 further filters the waste liquid flowing into the treatment tank 8. As the frame 16 moves, it pushes the residual filter residue in the treatment tank 8 to move, making it easier to discharge.

[0032] A mounting base 15 is fixedly installed on the upper surface of the processing box 8. A screw 18 is rotatably connected to the mounting base 15. The screw 18 passes through and screws onto a filter plate 17. The filter plate 17 is fixedly connected to the frame 16. A through slot is opened on the upper surface of the processing box 8 for the filter plate 17 to pass through. A motor 3 is fixedly installed on one side of the mounting base 15. The motor 3 drives the screw 18 to rotate, which can move the filter plate 17 screwed to the screw 18. This causes the frame 16 fixedly connected to the filter plate 17 to move within the screw 18. The movement of the frame 16 within the processing box 8 pushes the residue on one side of the frame 16, causing it to be discharged through the discharge port 3.

[0033] A transfer pump 12 is fixedly installed on one side of the bottom wall of treatment tank 1. The output end of the transfer pump 12 is connected to the inside of treatment tank 1. The output end of the transfer pump 12 is connected to the transfer pipe 2 5. A control valve is set at the connection between the output end of the transfer pump 12 and treatment tank 1. When the control valve is opened, the waste liquid in treatment tank 1 can be transferred to treatment tank 2 through the transfer pipe 2 5 by the transfer pump 12, thereby performing multiple filtration treatments on the waste liquid continuously neutralized by acesulfame.

[0034] Example 2:

[0035] This embodiment is used to address the problem of how to improve the efficiency of waste liquid treatment.

[0036] Please see Figures 1-5 As shown in the figure, the multi-stage waste liquid treatment device based on the acesulfame K continuous neutralization process in this embodiment has a motor 6 fixedly installed on the upper surface of the treatment tank 1. The output end of the motor 6 is fixedly connected to a stirring shaft 13 located inside the treatment tank 2. Vertically spaced stirring rods 14 are fixedly connected to the outer contour of the stirring shaft 13. When the motor 6 is started, the output end of the motor 6 drives the stirring shaft 13 to rotate. The stirring rods 14 fixedly connected to the stirring shaft 13 stir the waste liquid in the treatment tank 2, which can neutralize the waste liquid again and mix it thoroughly.

[0037] Combining Example 1 and Example 2

[0038] By setting up a filter assembly 1 to perform preliminary filtration of the waste liquid, impurities such as suspended solids and particulate matter are effectively removed, providing cleaner waste liquid for subsequent neutralization treatment. Filter assembly 2 filters the waste liquid again. Through multi-stage filtration and neutralization treatment, solvent waste and environmental pollution are effectively reduced. The product quality of the acesulfame K continuous neutralization process is not affected by impurities in the waste liquid, improving the purity and stability of the product. Stirring rod 14 rotates in treatment tank 2 to fully stir the waste liquid, ensuring that the neutralizing agent and acidic substances in the waste liquid can fully contact and react, thereby accelerating the neutralization speed and improving the treatment efficiency.
