[0034] Please refer to Figures 1-5 , as a supplementary implementation manner of a chemical wastewater treatment device for the stable stirring mechanism, liquid adding mechanism and adding auxiliary mechanism: A cover 20 is fitted to the top open end of the treatment tank 1. The cover 20 is respectively provided with a wastewater pipe 21 and a treatment liquid pipe 22 in a penetrating manner. A guide groove 23 is formed on the inner wall of the flow tube 9. A guide block 24 is installed on the side surface of the threaded push tube 16, and the guide block 24 can extend into the guide groove 23 for guiding cooperation. A connecting plate 25 is installed at the bottom of the outer wall of the flow tube 9, and the connecting plate 25 is fixedly installed on the top end surface of the cover 20. And the two flow tubes 9 are respectively connected in a penetrating manner with the wastewater pipe 21 and the treatment liquid pipe 22.

A discharge pipe 29 is provided in a penetrating manner at the bottom of the treatment tank 1, and a discharge valve 30 is installed on the discharge pipe 29.

[0035] More specifically, the wastewater enters the flow tube 9 through the wastewater pipe 21, and the treatment liquid enters the flow tube 9 through the treatment liquid pipe 22. The adding auxiliary mechanism controls the amount of liquid added, which is achieved through the movement of the push block 12 and the triangular sealing plate 11. The stable stirring mechanism is started, and the spiral blade 6 rotates. The wastewater and the treatment liquid are fully mixed in the treatment tank 1. The mixed wastewater undergoes a chemical reaction in the treatment tank 1 to remove harmful substances. The treated wastewater passes through the discharge pipe 29 at the bottom, and the discharge is controlled by the discharge valve 30. During the whole process, the stirring intensity and the liquid addition amount can be adjusted through components such as the telescopic cylinder 2 and the threaded push tube 16 to optimize the treatment effect.

[0036] In summary, when the overall equipment is in use or operation: When the stable stirring mechanism needs to operate, first drive the telescopic cylinder 2. One end of the telescopic cylinder 2 extends into and is connected to the push rod 4. The push rod 4 is in threaded cooperation with the rotating frame 3. When the push rod 4 moves, the rotating frame 3 also moves accordingly. The rotating block 7 is installed on the rotating frame 3 and can slide in the rotating groove 5 on the inner wall of the treatment tank 1 to achieve rotational guidance. The spiral blade 6 on the mounting sleeve 8 starts to rotate as the rotating block 7 moves, stirring the wastewater in the treatment tank 1. Through the rotation of the spiral blade 6, the wastewater and the added chemical treatment liquid are fully mixed to promote the reaction.

[0037] When the operation of the liquid adding mechanism is required, the pushing block 12 slides in the movement groove 13 on the slope block 10, and its movement is controlled by the adding auxiliary mechanism. The movement of the pushing block 12 causes multiple groups of triangular sealing plates 11 to gradually close, controls the liquid flow in the circulation pipe 9, controls the closing degree of the triangular sealing plates 11, and controls the treatment liquid or wastewater to flow into the treatment tank 1 through the circulation pipe 9.

[0038] When the operation of the adding auxiliary mechanism is required, the rotating pipe 14 and the inner rotating pipe 15 are connected through linkage and rotate on the side wall and inner wall of the circulation pipe 9. Multiple groups of spring ejecting pins 17 are on the inner wall of the rotating pipe 14. Through the rotating pipe, the spring ejecting pins 17 are gradually inserted into the deep groove holes 19 of the rotating groove 18 to achieve locking. The inner wall of the inner rotating pipe 15 is in threaded cooperation with the outer wall of the threaded pushing pipe 16. By rotating the inner rotating pipe 15, the threaded pushing pipe 16 pushes the pushing block 12 to move. By controlling the rotation of the rotating pipe 14 and the inner rotating pipe 15, the flow rate of the liquid can be accurately controlled.

[0039] The wastewater enters the circulation pipe 9 through the wastewater pipe 21, and the treatment liquid enters the circulation pipe 9 through the treatment liquid pipe 22. The adding auxiliary mechanism controls the amount of liquid added, which is achieved through the movement of the pushing block 12 and the triangular sealing plates 11.
