[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-6As shown, a ceramic membrane filter for treating waste acid from lead-acid batteries includes a filter body, a filter chamber 101, a filter mechanism inside the filter chamber 101, and a tubular ceramic membrane 203. A lower support tube 205 is fixedly connected to the lower end of the tubular ceramic membrane 203. An indicator mechanism is located below the filter mechanism, and a drive mechanism is located below the filter chamber 101 to drive the tubular ceramic membrane 203 to rotate. The indicator mechanism includes a rotating tube 401, a prism tube 402 fixedly connected to the top of the rotating tube 401, and the prism tube 402 is slidably connected to the lower support tube 205. A fixed connection is established between the lower support tube 205 and the rotating tube 401. A spring 404 is rotatably connected to an indicator rod 403 at the lower end of the lower support tube 205. One end of the indicator rod 403 extends to the outside of the filter chamber 101, and the indicator rod 403 is slidably connected to the filter chamber 101. A scale line is provided on the filter chamber 101 near the indicator rod 403. When unfilterable materials accumulate on the tubular ceramic membrane 203, the weight of the tubular ceramic membrane 203 will inevitably increase. Under the action of gravity, the tubular ceramic membrane 203 presses the lower support tube 205 downward, and the lower support tube 205 drives the indicator rod 403 to descend. At this time, the spring 404 is compressed. The staff can judge whether the tubular ceramic membrane 203 needs to be cleaned according to the position of the indicator rod 403.

[0029] A liquid outlet chamber 102 is fixedly connected to the top of the filter chamber 101. A concentrate drain pipe 105 is fixedly connected to one side of the liquid outlet chamber 102. A filtrate drain pipe 104 is fixedly connected to the top of the liquid outlet chamber 102. The lower end of the filtrate drain pipe 104 extends into the filter chamber 101. An inlet chamber 103 is fixedly connected to the bottom of the filter chamber 101. A raw liquid inlet pipe 107 is fixedly connected below the inlet chamber 103. A base bracket 106 is fixedly connected to the lower end of the filter chamber 101. Waste acid raw liquid enters the inlet chamber 103 through the raw liquid inlet pipe 107. After the waste acid raw liquid is driven by the power mechanism to rotate the tubular ceramic membrane 203, it enters the filter chamber 101. The waste acid raw liquid enters the filtration mechanism. The filtrate leaves the filter through the filtrate drain pipe 104. The concentrate passes through the filtration mechanism and enters the liquid outlet chamber 102. Then, it leaves the filter through the concentrate drain pipe 105 and enters the next cycle.

[0030] A top partition 201 is fixedly connected to the upper end of the inner wall of the filter chamber 101. Several circumferentially evenly arranged upper support tubes 202 are rotatably connected to the top partition 201. The lower end of the upper support tubes 202 is fixedly connected to the top of the tubular ceramic membrane 203. A lower partition 204 is fixedly connected to the lower end of the inner wall of the filter chamber 101. Lower support tubes 205 are circumferentially evenly arranged on the lower partition 204. The lower support tubes 205 are rotatably connected to the lower partition 204. Waste acid raw liquid enters the tubular ceramic membrane 203 from the lower support tube 205. The cross-flow filtration of the tubular ceramic membrane 203 discharges small molecules in the waste acid from the side wall of the tubular ceramic membrane 203. Large molecules that cannot pass through the tubular ceramic membrane 203 are carried away from the tubular ceramic membrane 203 by the subsequent pressurized liquid. This liquid is a concentrate. Under the action of the circulation pump, the concentrate enters the filter from the raw liquid inlet pipe 107 for the next filtration.

[0031] The drive mechanism includes a power partition 306 fixedly connected to the top of the liquid inlet chamber 103. A drive shaft 302 is rotatably connected to the middle of the power partition 306. Several evenly arranged rotating blades 301 are fixedly connected to the lower end of the drive shaft 302. A drive gear 303 is fixedly connected to the top of the drive shaft 302. Several evenly arranged driven gear rings 304 are meshed on the side of the drive gear 303. The driven gear rings 304 are fixedly connected to the rotating pipe 401 and rotatably connected to the top of the power partition 306. A liquid inlet support 305 is fixedly connected to the lower end of the power partition 306. The lower end of the liquid inlet support 305 abuts against the inner wall of the liquid inlet chamber 103. The liquid inlet support 305 is located directly above the raw liquid inlet pipe 107. 301 is fitted inside the liquid inlet support 305. The lower end of the rotating tube 401 is connected to the liquid inlet chamber 103, and the upper end of the rotating tube 401 is connected to the lower support tube 205 through the prismatic tube 402. Waste acid raw liquid with a certain pressure enters the liquid inlet chamber 103 from the raw liquid inlet pipe 107. The waste acid raw liquid drives the rotating blade 301 to rotate. The rotating blade 301 drives the transmission shaft 302 to rotate. The transmission shaft 302 drives the drive gear 303 to rotate. The drive gear 303 drives the driven gear ring 304 to rotate. The driven gear ring 304 drives the rotating tube 401 to rotate. The rotating tube 401 drives the prismatic tube 402 to rotate. The prismatic tube 402 drives the lower support tube 205 to rotate. The lower support tube 205 drives the tubular ceramic membrane 203 to rotate.

[0032] Working Principle: Waste acid stock solution enters the inlet chamber 103 through the stock solution inlet pipe 107. The waste acid stock solution is driven by the rotating blade 301, which in turn drives the transmission shaft 302. The transmission shaft 302 drives the drive gear 303, which in turn drives the driven gear ring 304. The driven gear ring 304 drives the rotating tube 401, which in turn drives the prismatic tube 402. The prismatic tube 402 drives the lower support tube 205, which in turn drives the tubular ceramic membrane 203. The waste acid enters the filter chamber 101 through the rotating tube 401, and the waste acid stock solution enters the filtration mechanism. The waste acid stock solution then enters the tubular ceramic membrane 203 through the lower support tube 205. The cross-flow filtration of the tubular ceramic membrane 203 removes small molecules from the side wall of the membrane. Large molecules that cannot pass through the tubular ceramic membrane 203 are carried away by the subsequent pressurized liquid. This liquid is a concentrate. Under the action of the circulation pump, the concentrate enters the filter from the raw liquid inlet pipe 107 for the next filtration. The filtrate leaves the filter from the filtrate outlet pipe 104. The concentrate passes through the filtration mechanism and enters the outlet chamber 102. Then, it leaves the filter from the concentrate outlet pipe 105 to enter the next cycle. As unfilterable substances accumulate on the tubular ceramic membrane 203, the weight of the tubular ceramic membrane 203 will inevitably increase. Under the action of gravity, the tubular ceramic membrane 203 compresses the support pipe 205 and moves it downward. The lower support pipe 205 drives the indicator rod 403 to descend. At this time, the spring 404 is compressed. The staff can judge whether the tubular ceramic membrane 203 needs to be cleaned based on the position of the indicator rod 403.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
