[0002] "Lithium battery" is a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. The lithium metal battery was first proposed and studied by Gilbert N. Lewis in 1912. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. During the treatment process of existing lithium battery wastewater, it is necessary to filter the wastewater.

[0003] For example, in a lithium battery wastewater treatment system with the Chinese authorized patent publication number CN215352449U, it is proposed that during the treatment process of existing lithium battery wastewater, it is necessary to filter the wastewater. The traditional treatment method is to filter and separate through a filter screen. However, as the filtered debris increases, it is easy to cause the filter holes of the filter screen to become blocked, reducing the treatment effect of lithium battery wastewater. It includes a treatment tank, and a support plate is fixed between the inner walls on both sides of the treatment tank. A first channel is vertically opened on the top side wall of the support plate; in the utility model, through the set turning plate and filter screen, chemical precipitation and impurity filtration treatment can be carried out on lithium battery wastewater, integrating precipitation and filtration, reducing the treatment cost of lithium battery wastewater. Through the cooperation of the set cam and slide plate, the impurities on the surface of the filter screen can be shaken and separated, reducing the blockage degree of the filter screen and improving the practicability.

[0004] However, the above treatment system is provided with a filter screen, and the filter screen is still prone to blockage after long-term filtration, resulting in an imperfect slag filtering effect of the filter screen and reducing the filtration efficiency of lithium battery wastewater.

[0030] Embodiment

[0031] Referring to Figures 1-7 As shown, a lithium battery wastewater treatment system includes a box body 1. A partition board 211 is fixed at the middle position of the box body 1. The partition board 211 and the inside of the box body 1 enclose a closed filtration tank 212 and a sedimentation tank 213. The sedimentation tank 213 can perform filtration, and the filtered wastewater is precipitated through the inside of the sedimentation tank 213. The inner wall of the filtration tank 212 is slidably connected with an inclined filter plate 214. A sliding block 215 is fixed on the outer wall of the filter plate 214. A sliding groove 216 matching with the sliding block 215 is opened on the inner wall of the filtration tank 212. The filter plate 214 can filter impurities in the wastewater. A slag cleaning port 217 is opened on the outer side wall of the filtration tank 212. A chamber 218 communicating with the slag cleaning port 217 is opened on the inner wall of the box body 1. A closing plate 219 is inserted into the chamber 218. When the filter plate 214 moves downward to correspond to the slag cleaning port 217, the closing plate 219 can be pulled downward, so as to open the slag cleaning port 217, which is convenient for cleaning the impurities on the filter plate 214 and discharging them through the slag cleaning port 217. A fixing block 221 is fixed on the outer wall of the closing plate 219. A groove 220 slidably matched with the fixing block 221 is opened on the outer wall of the box body 1. The outer wall of the fixing block 221 is connected to the outer wall of the box body 1 through a limiting mechanism. After moving the fixing block 221 up and down, it can slide along the inner wall of the groove 220 and drive the closing plate 219 to slide up and down for opening or closing the slag cleaning port 217.

[0032] The limiting mechanism includes a spring 222, a clamping block 223, a fixing plate 224 and a clamping groove 225.

[0033] A water pump 311 is installed on the right side of the partition plate 211. The input end of the water pump 311 is connected with a water outlet pipe 312 located inside the filter tank 212, and the output end is connected with a water inlet pipe 313 located inside the sedimentation tank 213. By starting the water pump 311, the wastewater in the filter tank 212 can enter the sedimentation tank 213 for sedimentation.

When the hanging plate 318 is moved, the sealing plate 319 is separated from the discharge port 314, facilitating the discharge of the sediment inside the box body 1 through the discharge port 314.

[0035] The inner wall of the sedimentation tank 213 is rotatably connected with two groups of screw rods 316 distributed in parallel. The outer walls of the two groups of screw rods 316 are threadedly connected with thread sleeves 317 fixed to the top of the hanging plate 318. The front ends of the two groups of screw rods 316 extend outside the sedimentation tank 213 and are connected through a transmission mechanism. A second motor 315 is installed at the rear end of the box body 1, and the output end of the second motor 315 is connected to any one of the screw rods 316.

Under the action of the thread, the thread sleeve 317, the hanging plate 318 and the sealing plate 319 are driven to move back and forth, achieving the effect of further cleaning the sediment. A sleeve block 321 is fixed to the top of the thread sleeve 317, and a fixing rod 320 penetrating the sleeve block 321 is fixed to the inner wall of the sedimentation tank 213.

[0036] Working principle: When in use, the lithium battery wastewater is added into the filtering tank 212. At this time, filtration can be carried out through the filter plate 214. After the filtration is completed, the first motor 229 is started to drive the rotating gear 230 to rotate and drive the rack plate 231 and the filter plate 214 to move downward, and the filter plate 214 is moved to correspond to the slag cleaning port 217. By pressing the two movable plates 227, the clamping blocks 223 are driven to be embedded into the fixed blocks 221. At this time, the spring 222 will be compressed, and the clamping blocks 223 are disengaged from the clamping grooves 225. The fixed block 221 is pulled downward to drive the closing plate 219 to descend and be received into the chamber 218. Subsequently, the staff can clean the surface of the filter plate 214 with a brush. At this time, the impurities on the filter plate 214 can be discharged through the slag cleaning port 217, achieving the purpose of efficient cleaning.

[0037] Subsequently, the water pump 311 is started to make the wastewater in the filtering tank 212 be added into the sedimentation tank 213 through the water outlet pipe 312 and the water inlet pipe 313, and sedimentation is carried out inside the sedimentation tank 213.

[0038] When the inside of the sedimentation tank 213 needs to be cleaned, the second motor 315 is started to drive the screw rod 316 to rotate, and the belt pulley 323 and the belt 324 are rotated, driving the other group of screw rods 316 to rotate. Under the action of the thread, the thread sleeve 317, the hanging plate 318 and the sealing plate 319 are driven to move forward, opening the discharge port 314, enabling the sediment to be discharged through the discharge port 314. And after the inside of the sedimentation tank 213 is filled with clean water, the second motor 315 is used to drive the hanging plate 318 and the sealing plate 319 to move back and forth, achieving the purpose of scraping the remaining sediment on the inner wall of the sedimentation tank 213 and achieving the cleaning effect.
