[0002] When conducting chemical experiments, chemical waste liquid is often generated during the experimental process. Most of such waste liquid has strong acidity or alkalinity. If directly discharged, it will not only damage the pipeline, but also pollute the environment.

[0003] The patent with publication number CN220502788U discloses a chemical waste liquid treatment device, including a carrier plate. Two installation openings are formed in the upper surface of the carrier plate. An acid waste liquid tank and an alkali waste liquid tank are respectively fixed in the two installation openings. Acid and alkali resistant valves are installed at the bottoms of the acid waste liquid tank and the alkali waste liquid tank. Acid and alkali resistant hoses are installed at the lower ends of the acid and alkali resistant valves. The lower ends of the acid and alkali resistant hoses are communicated with a neutralization reaction chamber. A suspension rod is fixedly connected to the middle position of the outer surface of the neutralization reaction chamber. The upper end of the suspension rod is rotatably connected to the lower surface of the carrier plate. A drain valve is installed at the lower position of the outer surface of the neutralization reaction chamber.

[0004] This device pours acid and alkali waste liquid into the interior of the reaction chamber for reaction. The waste liquid after reaction is directly discharged into the collection container on the upper side of the support plate. Since there may be some solid particles in the chemical waste liquid, direct discharge will cause pipeline blockage, and there may be harmful gases during the reaction process. The open discharge environment will cause gas leakage and harm to experimental personnel.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] The present utility model provides a chemical waste liquid treatment device as shown in Figures 1 to 4 which includes a recovery box body 1. Two groups of recovery tanks 11 are fixedly connected to the upper surface of the recovery box body 1. A filter cartridge 14 is clamped inside the recovery tank 11. Two groups of card slots 13 are opened at the upper end of the side wall of the recovery tank 11. A card block 15 is opened on the side surface of the filter cartridge 14. The card block 15 is clamped inside the card slot 13. A sealing cover 12 is clamped at the upper end of the recovery tank 11. A reaction box body 2 is fixedly connected to the inner bottom wall of the recovery box body 1. An observation window 17 is opened on the side surface of the recovery box body 1. A support frame 4 is fixedly connected to the lower end of the recovery box body 1. A collection box 41 is arranged inside the support frame 4. A liquid inlet hole 42 is opened on the upper surface of the collection box 41. A sealing baffle 43 is fixedly connected to the front side of the collection box 41. A suction pump 3 is fixedly installed at the rear side of the support frame 4. A suction pipeline 31 is fixedly connected to the upper end of the suction pump 3. The upper end of the suction pipeline 31 penetrates through the side wall of the recovery box body 1 and extends into the inside of the recovery box body 1. Two groups of suction heads 32 are fixedly connected to the end of the suction pipeline 31 far away from the suction pump 3. The lower end of the suction head 32 penetrates through the inner bottom wall of the recovery box body 1 and extends to the inside of the support frame 4.

[0033] Among them, the collection box 41 is placed inside the support frame 4 to collect the waste liquid. At this time, the sealing baffle 43 seals the side of the support frame 4. During use, the sealing cover 12 is lifted upward, and the waste liquid generated by the chemical experiment is poured into the two recovery tanks 11 respectively. At this time, the filter cartridge 14 inside the recovery tank 11 filters the poured waste liquid to prevent the waste residue inside the waste liquid from entering the recovery tank 11. At this time, the chemical waste liquid will slide into the reaction box body 2 through the recovery tank 11. At this time, the acid-base solution reacts and neutralizes inside the reaction box body 2, and then is discharged into the collection box 41 below. The waste gas generated during the discharge process will be blocked by the sealing baffle 43 inside the support frame 4. At this time, the suction machine 3 cooperates with the suction pipeline 31 and the suction head 32 to suck the waste gas inside the support frame 4 to prevent the waste gas from diffusing outward.

[0034] Refer to Figures 4 to 6 , two connecting blocks 21 are fixedly connected to the upper surface of the reaction box body 2. The lower ends of the two recovery tanks 11 are both fixedly connected with infusion pipelines 16. The lower ends of the infusion pipelines 16 are respectively fixedly connected with the two connecting blocks 21. Inclined guide plates 22 are fixedly connected to the left and right inner walls of the reaction box body 2. The front and rear ends of the two guide plates 22 are respectively fixedly connected to the front and rear inner walls of the reaction box body 2. A support plate is fixedly connected between the two guide plates 22. A spiral mixing hopper 23 is fixedly connected to the middle of the support plate. The lower end of the spiral mixing hopper 23 is fixedly connected with a drainage pipeline 24. The lower end of the drainage pipeline 24 penetrates through the inner bottom wall of the recovery box body 1 and extends to the inside of the support frame 4. The upper end of the drainage pipeline 24 is rotatably connected with a propeller blade 25.

[0035] In addition, during the reaction of the waste liquid, the valve at the lower end of the recovery tank 11 is opened through the observation frame 17, so that the waste liquid inside the recovery tank 11 is discharged into the reaction box body 2. The waste liquid sliding into the reaction box body 2 quickly slides into the spiral mixing hopper 23 through the inclined guide plate 22. Since the inner wall of the spiral mixing hopper 23 is in a funnel shape and is provided with threaded grooves, the waste liquid flowing in under the action of the threaded grooves will rotate inside the spiral mixing hopper 23, thereby enabling the acid-base solution to carry out a mixing reaction. Then, when the waste liquid passes through the propeller blade 25, it will drive the propeller blade 25 to rotate and accelerate the rotation speed of the waste liquid, enabling the waste liquid to be accelerated and fused, improving the waste liquid fusion speed, and the fused waste liquid is directly discharged into the collection box 41.

[0036] The working principle of the present utility model: The filter cartridge 14 filters the poured waste liquid to prevent the waste residue in the waste liquid from blocking the pipeline. At the same time, the acid-base waste liquid slides into the reaction box body 2 for mixing reaction, and then the mixed waste liquid is discharged into the collection box 41. At this time, the sealing baffle 43 blocks the front side of the support frame 4 to prevent the waste gas from drifting outward, and the waste gas is sucked by the suction machine 3 to improve the safety of waste liquid treatment.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the descriptions in the specification are only preferred examples of the present utility model, which are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
