Description

Technical Field

[0001] The present invention relates to a lithium battery production waste liquid treatment device, and specifically relates to the field of lithium battery production waste liquid treatment. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Lithium batteries produce a large amount of waste liquid during production. The waste liquid has a complex composition and generally contains biotoxic and bio-resistant substances, so it needs to be treated before it can be discharged.

[0003] At present, the chemical oxidation decomposition method is generally used to treat the waste liquid produced by lithium batteries. The battery waste liquid is injected into a sedimentation tank and a flocculant is injected. The toxic substances in the waste liquid are precipitated at the bottom of the sedimentation tank by the flocculant. Then the waste liquid treated with sediment is injected into the reaction tank and the Fenton reagent is injected. The waste liquid is subjected to secondary treatment by the Fenton reagent. The existing sedimentation tank and the reaction tank are generally connected by pipes and are installed separately without being connected together. This occupies a large area. When the waste liquid in the sedimentation tank is injected into the reaction tank, the sediment is easily entered into the reaction tank along with the waste liquid. This will affect the effect of the Fenton reagent on the waste liquid treatment, resulting in an unsatisfactory treatment effect. In addition, the existing sedimentation tank has a relatively simple structure and does not have the function of automatically cleaning the sediment. The sediment at the bottom of the sedimentation tank needs to be cleaned manually. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 2 The present invention provides a technical solution: a lithium battery production waste liquid treatment device, comprising a workbench 1, the top of the workbench 1 is fixedly connected to a workbench bracket 2, the top of the workbench bracket 2 is fixedly connected to a filtering device 3, the bottom of the filtering device 3 is fixedly connected to a stirring device 4, the side of the stirring device 4 is fixedly connected to a medicine delivery device 5 through a bracket, the bottom of the stirring device 4 is fixedly connected to a separation device 6, one side of the separation device 6 is fixedly connected to a collecting device 7, and the side of the separation device 6 away from the collecting device 7 is fixedly connected to an exhaust device 8.

[0021] When in use, the waste liquid is poured into the filtering device. After preliminary filtration by the filtering device 3, the waste liquid enters the stirring device 4 and cooperates with the medicine feeding device 5 to mix the medicine with the waste liquid, so that the waste liquid forms flocculent precipitation. The mixed waste liquid enters the separation device 6 to separate the clear liquid from the flocculent precipitation. The separated flocculent precipitation is collected by the collecting device 7. The exhaust device 8 arranged on the side of the stirring device 4 exhausts the inside of the stirring device 4 and forms a negative pressure inside it, thereby accelerating the processing speed, realizing the vertical assembly line processing of the waste liquid treatment, and reducing the floor space.

[0022] The floor space occupied by the waste liquid treatment system has been reduced. The entire waste liquid treatment process has been optimized into a vertical assembly line operation, making the treatment process more efficient and space-saving. Through the above technical improvements and equipment optimization, the modern waste liquid treatment system can significantly reduce operating costs and environmental impacts while ensuring the treatment effect, providing a reliable solution for waste liquid treatment in industrial production.

[0023] See also Figure 1-Figure 5 The filtering device 3 includes a filtering base 31, the filtering device 3 includes a filtering base 31, an electric telescopic rod 32 is fixedly connected to the top of the filtering base 31, a plurality of electric telescopic rods 32 are arranged, and the plurality of electric telescopic rods 32 are evenly distributed on the top of the filtering base 31, a filtering baffle 33 is fixedly connected to the top of the filtering base 31, a filtering bracket 34 is fixedly connected to the top of the electric telescopic rod 32, a filtering pool 35 is fixedly connected to one end of the filtering bracket 34 away from the electric telescopic rod 32, a first filtering opening 36 is provided at the bottom of the filtering pool 35, a first filtering opening 36 is fixedly connected to a first filter membrane 37, a second filtering opening 38 is provided at the top of the filtering base 31, and a second filter membrane 39 is fixedly connected to the second filtering opening 38.

[0024] When in use, the waste liquid is directly poured into the filter tank 35, and the waste liquid begins to be filtered and pre-treated under the action of gravity. The waste liquid is filtered through the first filter membrane 37 for the first step, and the filtered liquid is filtered for the second time through the second filter membrane 39 to preliminarily separate the liquid and solid. After the amount of solid impurities on the inner wall of the filter tank 35 accumulates to a certain extent, the electric telescopic rod 32 begins to rise, and the rise of the electric telescopic rod 32 drives the filter tank 35 to move upward, so that the filter tank 35 is separated from the filter base 31, which is convenient for cleaning impurities and replacing filter membranes. After cleaning and replacement, the electric telescopic rod 32 moves downward, driving the filter tank 35 to move downward, and returns to the original position to continue the filtering operation.

[0025] The automation of waste liquid pretreatment is realized, and the solids and liquids in the waste liquid are effectively separated in the vertical direction. The treated liquid can directly enter the next processing stage without manual intervention, thereby improving the processing efficiency and the consistency of the process. At the same time, the solid particles separated by the filtration device are also easier to clean and further separate, making the entire waste liquid treatment system more environmentally friendly and cost-effective. This automated pretreatment technology not only improves the efficiency and accuracy of waste liquid treatment, but also reduces the workload of operators. It is an indispensable and important link in modern industrial production.

A driven stirring tube 411 is fixedly connected to the end of the driven gear 410 away from the limiting seat 47, and stirring blades 43 are fixedly connected to the sides of the active stirring tube 42 and the driven stirring tube 411. A medicine release hole 412 is opened on the side of the driven stirring tube 411, and a rotating hydraulic joint 413 is connected to the end of the driven stirring tube 411 away from the driven gear 410.

A gear base 416 is fixedly connected to the bottom of the transmission gear 46, and a downward pressure blade 417 is fixedly connected to the side of the gear base 416. The bottom of the gear base 416 is rotatably connected to the center position of the bottom of the stirring pool 41, and the active stirring tube 42 is connected to an external power supply device through a belt transmission mechanism.

[0027] When in use, the active stirring tube 42 starts to rotate under the action of the servo motor, and the rotation of the active stirring tube 42 drives the stirring blade 43 fixed on the side of the active stirring tube 42 to rotate, and the stirring blade 43 starts to stir the waste liquid, and the rotation of the stirring blade 43 drives the driving gear 44 to rotate, and the rotation of the driving gear 44 drives the transmission gear 46 to rotate, and the rotation of the transmission gear 46 drives the driven gear 410 to rotate, and the rotation of the driven gear 410 drives the driven stirring tube 411 to rotate, and the first limiting shaft 45 is rotatably connected to the bearing on the limiting sleeve 48 to prevent the stirring tube from shifting during the stirring process, and the medicine is injected into the driven stirring tube 411 through the rotating hydraulic joint 413, and is mixed with the filtered waste liquid through the medicine release hole 412, and the rotation of the transmission gear 46 drives the gear base 416 to rotate, and the gear base 416 drives the downward pressing blade 417 to rotate, so as to promote the waste liquid after mixing to enter the next processing stage through the guide pipe 415.

[0028] The reagent and the waste liquid to be treated are fully mixed. Through the design of the system, the reagent and the waste liquid to be treated can be fully mixed, which greatly accelerates the mixing process and significantly improves the processing efficiency. In particular, while the stirring tube is rotating, the reagent and the waste liquid are mixed more thoroughly, which promotes the effective combination of harmful substances in the waste liquid and the reagent. This design not only makes the waste liquid treatment process faster, but also ensures the full utilization of the reagent, thereby reducing the cost of waste liquid treatment and improving the treatment effect.

[0029] See also Figure 1-Figure 11 The medicine delivery device 5 includes a medicine box 51, a medicine screw 52 passes through and is rotatably connected to the side of the medicine box 51, a medicine bracket 53 is fixedly connected to the other side of the medicine box 51 relative to the medicine screw 52, ​​a plurality of medicine brackets 53 are arranged, and the plurality of medicine brackets 53 are evenly arranged on the side of the medicine box 51, the medicine screw 52 passes through and is rotatably connected to a medicine push plate 54, an injection check valve 55 passes through and is connected to the top of the medicine box 51, an output check valve 56 is connected to the other side of the medicine box 51 relative to the medicine screw 52, ​​the output check valve 56 is connected to a medicine conduit 57 at one end away from the medicine box 51, a medicine injection pipe 58 is connected to the side of the medicine conduit 57, a plurality of medicine injection pipes 58 are arranged, and the plurality of medicine injection pipes 58 are evenly distributed on the side of the medicine conduit 57.

[0030] During use, the medicine is injected into the medicine box 51 through the injection check valve 55, and the medicine screw 52 starts to rotate under the action of the servo motor. The rotation of the medicine screw 52 drives the medicine push plate 54 to move, and the medicine push plate 54 moves to squeeze the medicine. The medicine is transported out from the output check valve 56 and enters the medicine conduit 57. The medicine is transported to the medicine injection pipe 58 through the medicine conduit 57 and enters the stirring device to mix with the waste liquid. The selection of the injection check valve 55 allows the medicine to pass through unidirectionally, avoiding overflow from the injection check valve 55 during drug delivery. The selection of the output check valve 56 effectively avoids the waste liquid from flowing back into the medicine box 51 during stirring. The selection of the medicine screw 52 realizes the precise use of the drug dosage during the stirring process.

[0031] The reagent is mixed into the waste liquid while stirring, and the dosage of the reagent can be controlled synchronously during the stirring process, providing different dosages of the reagent to mix with the waste liquid at different stirring stages. This technological innovation enables the dosage of the reagent to be controlled in real time during the mixing process, ensuring that the reagent can be accurately added to the waste liquid while the waste liquid is stirred. The system can automatically adjust the amount of reagent input according to different stirring stages and waste liquid characteristics to achieve the best treatment effect. This method of synchronously controlling the dosage of the reagent not only improves the accuracy and efficiency of waste liquid treatment, but also ensures that the harmful components in the waste liquid are fully mixed with the reagent, thereby effectively reducing the content of pollutants and improving the quality of the treated waste liquid. By optimizing the reagent input process, the system not only reduces the treatment cost, but also makes the waste liquid treatment process more environmentally friendly and sustainable.

[0032] See also Figure 1-Figure 14 The separation device 6 includes a separation shell 61, and the side of the separation shell 61 is connected with a guide pipe 62. The guide pipe 62 is arranged in multiple groups, and the multiple groups of guide pipes 62 are evenly arranged on the side of the separation shell 61.

[0033] When in use, the waste liquid that has been stirred enters through the separation inlet 64, and the separation screw 67 is driven to rotate under the action of the servo motor. The rotation of the separation screw 67 drives the separation push plate 68 to move, and the separation push plate 68 moves to squeeze the incoming waste liquid, so as to separate the waste liquid into flocculent sediment and clear liquid. At the same time, during the movement of the separation push plate 68, the horizontal plate arranged on the separation push plate 68 blocks the separation inlet 64 to prevent the waste liquid to be separated and the separated clear liquid from mixing. The separated clear liquid is transported out from the clear liquid outlet 69 and is completely discharged when the separation push plate 68 returns, thereby realizing the automatic separation of flocculent sediment and clear liquid of the waste liquid that has been stirred and the automatic transportation of the flocculent sediment and clear liquid. Compared with the traditional natural sedimentation process, the sedimentation process is accelerated and the automated separation operation is realized.
