[0033] See also Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments:

[0034] Example 1:

[0035] In an embodiment of the present invention, a lead-acid battery recycling wastewater treatment device includes a body 1, a waste liquid delivery pipe 2 is fixedly installed on the top of the body 1, and is used to introduce battery wastewater into the interior of the body 1. A filter frame 6 is provided inside the body 1, and a side collection ring frame 7 is fixedly installed on the outside of the filter frame 6. The side collection ring frame 7 is fixedly installed inside the body 1. The filter frame 6 is used to perform preliminary filtration on the transported battery wastewater;

[0036] In the embodiment of the present invention, when treating battery wastewater, the battery wastewater is first introduced into the interior of the body 1 through the waste liquid delivery pipe 2. At this time, the battery wastewater can be preliminarily filtered through the filter frame 6 to remove impurities contained in the battery wastewater;

[0037] A liquid inlet pipe 101 is fixedly installed on the outside of the body 1. The liquid inlet pipe 101 is used to introduce chemicals into the body 1 so that the battery waste water reacts with the chemicals.

[0038] The chemical agent is an existing agent used to react with the battery wastewater to form a precipitate, so it will not be described in detail here;

[0039] In the embodiment of the present invention, an annular frame 9 is fixedly installed inside the body 1, a feed pipe 10 is fixedly installed at the bottom of the annular frame 9, a filter cartridge 11 is fixedly installed at the end of the feed pipe 10, and a drive frame 12 is fixedly installed at the end of the filter cartridge 11. The filter cartridge 11 is used to filter the precipitate generated by the reaction of battery wastewater and chemical agents;

[0040] In the embodiment of the present invention, the annular frame 9 and the body 1 are sealed. After the battery wastewater is initially filtered by the filter frame 6, it can flow into the annular frame 9. Then, by injecting chemicals into the body 1, the chemicals can enter the annular frame 9 and react with the battery wastewater. The reacted battery wastewater is then discharged through the discharge pipe 10.

[0041] When the battery wastewater after the reaction is discharged through the discharge pipe 10, it can enter the interior of the filter cartridge 11. At this time, the sediment in the battery wastewater can be filtered out through the filter cartridge 11, and the battery wastewater can pass through the filter cartridge 11 to be discharged;

[0042] In the embodiment of the present invention, a control valve 1001 is fixedly installed inside the feed pipe 10, a filter baffle 15 is fixedly installed on the inner bottom of the body 1, and the filter baffle 15 is fixedly installed on the bottom of the annular frame 9, which is used to perform secondary filtration on the waste liquid filtered by the filter cartridge 11. A drain pipe 102 is fixedly installed on the side of the body 1, and the drain pipe 102 is used to discharge the filtered waste liquid;

[0043] In the embodiment of the present invention, the control valve 1001 is an existing device and will not be described in detail here;

[0044] In the embodiment of the present invention, the filter baffle 15 is used to perform secondary filtration on the battery wastewater after the reaction until the battery wastewater is discharged through the drain pipe 102;

[0045] A cleaning shaft 1101 is rotatably mounted inside the filter cartridge 11 and the drive frame 12. A spiral cleaning sheet 1102 is fixedly mounted on the outside of the cleaning shaft 1101.

[0046] By cooperating with the filter frame 6 and the annular frame 9, the filter frame 6 can be used to perform preliminary filtration during the transportation of the battery wastewater. Then, after the chemical agent is introduced into the body 1 and fully reacts with the battery wastewater, the battery wastewater is discharged through the discharge pipe 10. During the discharge process, the filter cartridge 11 can be used to automatically clean and collect the sediment. Compared with traditional wastewater treatment equipment, the treatment effect of the battery wastewater can be further improved, and the maintenance convenience of the equipment is improved.

[0047] In the embodiment of the present invention, the servo motor 1201 is an existing device, which is used to drive the cleaning shaft 1101 to rotate. The spiral cleaning blade 1102 is used to complete the transportation of sediment and to clean the filter cartridge 11 at the same time.

[0051] A cleaning scraper 501 is slidably mounted inside the side collecting ring frame 7. A positioning ring 5 is fixedly sleeved on the outside of the mixing shaft 4, and a cleaning scraper 501 is fixedly mounted on the outside of the positioning ring 5. The cleaning scraper 501 is in contact with the top of the filter frame 6 and the end thereof extends into the inside of the side collecting ring frame 7. A plurality of drainage holes 702 are provided at the bottom of the side collecting ring frame 7.

[0052] In the embodiment of the present invention, the side collecting ring frame 7 is used to collect impurities filtered out by the filter frame 6. When the positioning ring 5 rotates with the mixing shaft 4 and drives the cleaning scraper 501 to run, the cleaning scraper 501 can move along the top of the filter frame 6, and push the impurities attached to the surface of the filter frame 6 into the inside of the side collecting ring frame 7. The cleaning scraper 501 slides inside the side collecting ring frame 7, and can push the impurities to the discharge port 701, and then the waste discharge frame 8 completes the cleaning of the filter frame 6 and the conveying of impurities.

[0058] Example 2: Based on Example 1, a method for treating wastewater from lead-acid battery recycling, based on the above-mentioned wastewater treatment device, specifically includes the following steps:

[0059] S1. First, the battery wastewater to be treated is introduced into the waste liquid delivery rack 3 through the waste liquid delivery pipe 2, so that the battery wastewater can flow downward through the multiple through holes 301 until it completes preliminary filtration through the filter rack 6 and enters the annular rack 9. At this time, the chemical agent is introduced into the body 1 through the liquid inlet pipe 101, and then the mixing shaft 4 drives the multiple mixing plates 401 to rotate, stirring the battery wastewater so that it mixes and reacts with the chemical agent. Then, as the control valve 1001 is opened, the battery wastewater and sediment can be discharged through the discharge pipe 10, and the battery wastewater can flow out through the filter cartridge 11. Then, after completing secondary filtration through the filter baffle 15, it is discharged through the drain pipe 102;

[0060] S2. The filter cartridge 11 can filter the sediment generated by the mixed reaction of battery wastewater and chemical agents. As the cleaning shaft 1101 runs, it can drive the spiral cleaning sheet 1102 to rotate inside the filter cartridge 11 to achieve the cleaning and transportation operation of the sediment.

[0061] S3. When the filter rack 6 completes the preliminary filtration of the battery waste liquid, the rotation of the mixing shaft 4 can drive the cleaning scraper 501 to run through the positioning ring 5, thereby cleaning the outer surface of the filter rack 6. As the end of the cleaning scraper 501 extends to the inside of the side collection ring rack 7, the impurities inside the side collection ring rack 7 can be pushed until the impurities are discharged through the discharge port 701.
