[0002] In polymerization production, the main sources of wastewater include polymerizer wall washing water, condensate from slurry stripping tower, drainage from VCM (vinyl chloride monomer) storage tank, and drainage from vacuum pump working water of stripping tower. These wastewaters are collected in wastewater storage tanks. During the treatment process, adjusting the pH value of wastewater is an important link, which can affect the solubility of pollutants in wastewater, the activity of microorganisms, and the effect of subsequent treatment processes.

[0003] However, after the waste liquid is discharged into the neutralization tank, in order to speed up the neutralization efficiency of the waste liquid and the acidic and alkaline substances, the waste liquid and the acidic and alkaline substances need to be mixed by a stirring component. The existing stirring component usually stirs the liquid in the middle part of the tank body, and the liquid on both sides of the tank body cannot be mixed evenly with the acidic and alkaline substances, which is not conducive to improving the neutralization speed of the waste liquid and the acidic and alkaline substances.

When the fixing rods 701 drive the mixing rod 702 to rotate, the mixing rod 702 can be used to stir the waste liquid in the middle of the pool body 202.

[0026] As a technical optimization solution of the utility model, the two groups of connecting rods 703 are symmetrically arranged about the rotating shaft 5, and the stirring rod 705 is inclined.

The long rod 6 is located at one end of the connecting rod 703, so that the connecting rod 703 can stir the waste liquid on both sides of the pool body 202.

[0028] As a technical optimization solution of the utility model, the rotating shaft 5 and the long rod 6 are both rotatably connected to the cover plate 1, and the two long rods 6 are symmetrically arranged about the rotating shaft 5. When the long rod 6 rotates, it can drive the connecting rod 703 to rotate.

[0029] As a technical optimization scheme of the utility model, the driving mechanism 4 includes a guide wheel 402 and a belt 403. The guide wheel 402 is fixedly installed on the rotating shaft 5 and the long rod 6. Several guide wheels 402 are sleeved with belts 403. The cover plate 1 is fixedly installed with a motor 401. The output end of the motor 401 is fixedly connected to the rotating shaft 5 through a coupling. When the motor 401 is started, the rotating shaft 5 can drive the guide wheel 402 to rotate, thereby rotating the belt 403.

[0030] As a technical optimization solution of the utility model, the motor 401 is located at the center of the top of the cover plate 1, and the plurality of guide wheels 402 are equidistantly arranged. When the guide wheels 402 rotate, the driving long rod 6 can rotate inside the cover plate 1.

[0031] As a technical optimization solution of the utility model, the feeding mechanism 3 includes a feeding hopper 301 and a sealing plate 302. The feeding hopper 301 is fixedly installed on the cover plate 1. The sealing plate 302 is snap-fitted onto the feeding hopper 301. A through groove 304 is provided on the cover plate 1. A handle 303 is fixedly installed on the feeding hopper 301. The sealing plate 302 can be taken out from the feeding hopper 301 by means of the handle 303.

[0032] As a technical optimization solution of the utility model, the two upper hoppers 301 and the through groove 304 are symmetrically arranged, and the portion of the cover plate 1 close to the through groove 304 is arranged in an inclined structure. When acidic and alkaline substances are poured into the upper hopper 301, they can be discharged into the pool body 202 through the through groove 304, and then mixed with the waste liquid.

[0033] As a technical optimization solution of the utility model, the main body structure 2 includes a base plate 201 and a pool body 202.

[0034] When the utility model is in use, first, the operator can discharge the waste liquid into the pool body 202 through the water inlet 203, then pick up the handle 303, which can drive the sealing plate 302 to separate from the upper hopper 301 fixed on the cover plate 1, and the operator adds the acid and alkaline substances needed to treat the waste liquid into the upper hopper 301. Since the through groove 304 provided on the cover plate 1 is connected with the upper hopper 301 and the pool body 202, the acid and alkaline substances are discharged into the pool body 202 through the through groove 304, and then turn on the control switch of the motor 401. The motor 401 is installed at the top of the cover plate 1. When the motor 401 drives the rotating shaft 5 fixed at the output end to rotate, the rotating shaft 5 can drive a guide wheel 402 fixed on the side wall to rotate, and the other two guide wheels 402 are fixed on the side walls of the long rod 6. And a belt 403 is wound around several guide wheels 402. When the guide wheel 402 fixed on the rotating shaft 5 rotates, the belt 403 can drive the other two guide wheels 402 to rotate, and then the guide wheel 402 drives the two long rods 6 to rotate inside the pool body 202. When the rotating shaft 5 rotates, several groups of fixed rods 701 equidistantly fixed on the side wall can drive the mixing rod 702 to rotate, and then the mixing rod 702 can stir the waste liquid in the middle part of the main body 2; when the long rod 6 rotates, the connecting rod 703 can drive the stirring rod 705 installed on the sleeve rod 704 to rotate. The two groups of stirring rods 705 are located on both sides of the main body 2, and then the stirring rod 705 can mix the waste liquid and acidic and alkaline substances in the main body 2 evenly, which is beneficial to improve the treatment effect of the waste liquid.
