[0019] Preferably, the lower end of the A-shaft 52 is also provided with an A-driven wheel 53, and the two sets of A-driven wheels 53 are respectively located at both ends of the driven bevel gear 51; the lower A-driven wheel 53 is connected to a C-driven wheel 56 via a belt drive, and a C-shaft 57 is fixedly connected to the C-driven wheel 56.

[0020] Preferably, the stirring assembly 6 includes multiple sets of stirring bodies 61 arranged in a circumferential array. Each stirring body 61 includes at least two horizontal bars 62 arranged symmetrically at the top and bottom. Each horizontal bar 62 has a vertical bar 63 at both ends.

[0024] Preferably, the tank body is provided with a viewing window 8, and a scale line is provided next to the viewing window 8.

[0025] Preferably, the lower part of the neutralization tank 30 is provided with a drain pipe 1-2.

[0026] As a specific embodiment of this utility model: Acidic waste liquid enters acidic waste liquid tank 10 through inlet 18, and alkaline waste liquid enters alkaline waste liquid tank 20 through inlet 18. The acidic and alkaline waste liquids enter neutralization tank 30 through connecting pipe 1-1 for neutralization, and the neutralized waste liquid is discharged through drain pipe. Acidic waste liquid tank 10, alkaline waste liquid tank 20, and neutralization tank 30 are all equipped with viewing windows and scale lines for easy observation of their internal volumes.

[0027] When acidic waste liquid enters acidic waste liquid tank 10 through inlet 18 or alkaline waste liquid enters alkaline waste liquid tank 20 through inlet 18, the waste liquid first passes through filter dish 3. Impurities in the waste liquid are filtered by filter dish 3, which traps the impurities on the filter dish 3, facilitating subsequent neutralization of the waste liquid and improving the treatment quality. The filtered liquid then flows into storage section 2 for later use. The liquids in acidic waste liquid tank 10 and alkaline waste liquid tank 20 are stirred by stirring components 6 to prevent sedimentation from forming in the tanks over time, which would affect waste liquid discharge. When the acidic and alkaline waste liquids enter neutralization tank 30, the waste liquids are stirred by two symmetrically arranged stirring components 6, accelerating the mixing of acid and alkaline waste liquids and improving the neutralization reaction rate and efficiency.

[0028] The vertical rod 63 and horizontal rod 62 of the stirring assembly 6 are designed to facilitate large-scale stirring of waste liquid, providing stirring in both horizontal and vertical directions. The through hole 64 on the vertical rod 63 allows the liquid to pass back and forth through the through hole 64 during rotation, further improving the stirring efficiency.

[0029] Over time, filter dish 3 may become clogged. In this case, press down on the pressure column 17. The springs 16 at both ends of the pressure plate 11 are compressed, causing the pressure column 17, pressure plate 11, and unclogging tip 12 to move downwards, allowing the unclogging tip 12 to pass through the filter holes in filter dish 3 from top to bottom, thus clearing the filter holes. After releasing the pressure, the pressure column 17, pressure plate 11, and unclogging tip 12 move upwards back to their initial state under the action of the springs 16. The distribution of the unclogging tip 12 on the base plate corresponds one-to-one with the distribution of the filter holes on filter dish 3, and the unclogging tip 12 can pass through the filter holes. The unclogging section 1 and the liquid storage section 2 can be detachably connected using screws and nuts. The unclogging section 1 can be removed, the filter dish 3 taken out, the filter residue poured out, or the filter dish 3 cleaned, improving the efficiency of waste liquid filtration. Filter dish 3 can also be replaced, making it highly practical.

[0030] Drive transmission relationship of motor 4: When motor 4 is started, the drive shaft of motor 4 rotates, which drives the drive bevel gear 42 to rotate. The drive bevel gear 42 meshes with the driven bevel gear 51, causing shaft A 52 to rotate. The rotation of shaft A 52 drives the stirring components 6 at its upper and lower ends to rotate, and at the same time drives the two sets of driven wheels A 53 to rotate. Driven wheels A 53 drive shaft B 55 and shaft C 57 to rotate through belt transmission, causing the stirring components 6 on shaft B 55 and shaft C 57 to rotate.
