Description

Technical Field

[0001] This utility model relates to the field of battery waste liquid treatment technology, specifically a battery waste liquid treatment filtration device. Background Technology

[0002] Waste batteries come in many varieties, and the wastewater generated during recycling is complex, with high concentrations of toxic pollutants. The wastewater contains a large amount of pollutants and harmful heavy metals, and the non-ferrous metals in the batteries can pollute the environment, making wastewater recycling and treatment essential. According to a lithium-ion battery waste liquid filtration treatment device described in patent publication number CN214115126U, a reagent from an inlet tank is transported to a treatment tank through an inlet pipe. Simultaneously, a motor, rotating shaft, and stirring rod are used to stir and mix the waste liquid and reagent in the treatment tank, ensuring uniform mixing and improving the treatment effect. However, the reaction between the battery waste liquid and the reagent requires time. In this device, the waste liquid is filtered while reacting, which results in some waste liquid being filtered before it has had a chance to react with the reagent. Furthermore, after complete filtration, it is inconvenient to remove the precipitate.

[0003] Based on this, a battery waste liquid treatment filtration device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] In one embodiment, such as Figures 1-3 As shown, a battery waste liquid treatment and filtration device includes a treatment tank 100. Several support frames 101 are installed at the lower end of the treatment tank 100 to support it. An inlet 102 is installed at the upper end of the treatment tank 100, through which battery waste liquid is injected into the treatment tank 100. A reagent inlet 103 is provided at the upper end of the treatment tank 100, through which reagents are placed into the treatment tank 100. The interior of the treatment tank 100 is equipped with a mixing mechanism for fully mixing the waste liquid and the reagents. The upper end of the treatment tank 100 is equipped with an isolation mechanism for isolating unreacted waste liquid. The interior of the treatment tank 100 is equipped with a filtration mechanism for filtering the reacted liquid. The lower end of the treatment tank 100 is equipped with a collection mechanism for collecting precipitates.

[0024] In one embodiment, such as Figures 1-2 As shown, the mixing mechanism includes a rotating shaft 200, which is located at the bottom of the processing tank 100. The rotating shaft 200 drives the stirring plate 202 to rotate. The upper end of the rotating shaft 200 is connected to the output end of the motor 201, which is located at the upper end of the processing tank 100. The motor 201 drives the rotating shaft to rotate. Several stirring plates 202 are installed on the rotating shaft 200. The stirring plates 202 mix and stir the battery waste liquid and the reagent.

[0025] In one embodiment, such as Figures 1-2 As shown, the isolation mechanism includes an electric push rod 303, which is located at the upper end of the processing box 100. The electric push rod 303 drives the baffle 300 to move. The output end of the electric push rod 303 is connected to the baffle 300. The baffle 300 is slidably connected to the inside of the processing box 100. The baffle 300 isolates the battery waste liquid from the filter plate 400. A scraper 301 is installed on the upper part of the inside of the processing box 100 near the baffle 300. When the baffle 300 moves upward, the scraper 301 scrapes off the battery waste liquid on the baffle 300 to prevent the waste liquid from being carried out and polluting the environment.

[0026] In one embodiment, such as Figures 1-2 As shown, the filtration mechanism includes a filter plate 400, which is located inside the processing tank 100. The filter plate 400 is located on the side of the baffle 300 away from the stirring plate 202. The filter plate 400 filters the battery waste liquid after the reaction, allowing harmful substances to flow down and the treated waste liquid to be discharged.

[0027] In one embodiment, such as Figures 1-2 As shown, the collection mechanism includes a scraper 302, which is located at the bottom of the baffle 300 near the filter plate 400. The scraper 302 scrapes off the residual sediment on the filter plate 400. A collection chamber 500 is provided below the scraper 302 to collect the filtered sediment.

[0028] In one embodiment, such as Figures 1-3 As shown, a drain pipe 401 is installed at the end of the processing box 100 away from the rotating shaft 200, through which the processed battery waste liquid is discharged.

[0029] Example 2

[0030] In one embodiment, such as Figures 1-2 As shown, sealing strips are installed on both sides where the baffle 300 connects to the inner wall of the treatment box 100 to prevent battery waste liquid from flowing out through the connection between the baffle 300 and the treatment box 100.

[0031] In one embodiment, such as Figures 1-2 As shown, scraper 1 301 and scraper 2 302 are both made of rubber, which makes the scraper work better and has a longer service life.

[0032] Working principle: During use, battery waste liquid is injected into the treatment tank 100 through the liquid inlet 102, and the reagent is poured in through the reagent inlet 103. The motor 201 is started, which causes the rotating shaft 200 to drive the stirring plate 202 to rotate, so that the waste liquid and the reagent can react fully. After the reaction, the electric push rod 303 drives the baffle 300 to move upward. The scraper 1 301 scrapes the liquid on the baffle 300 to prevent the liquid from polluting the environment. The liquid is discharged through the filter plate 400 to the drain pipe. The filtered material will fall into the collection chamber 500. After filtration is completed, the electric push rod 303 drives the baffle 300 to move downward. The scraper 2 302 scrapes the residual material on the filter plate 400 and it falls into the collection chamber 500. The sediment can be removed by opening the bottom of the collection chamber 500.
