The extrusion block 29 will periodically extrude the baffle 28 in the process of rotation. When the extrusion block 29 extrudes the baffle 28, the baffle 28 drives the toothed plate 27 to move downward. When the extrusion block 29 no longer extrudes the baffle 28, the baffle 28 is automatically reset under the action of the first elastic member 214, thereby driving the toothed plate 27 to move upward. Such a cycle makes the toothed plate 27 continuously move up and down. In this process, the arc-shaped mesh cylinder 11 is always in a swinging state and cannot be turned over.

[0034] Please refer to Figure 2 and Figure 6The neutralizing mechanism 3 comprises a branch pipe 31 penetrating through the side wall of the treatment box 1, and the bottom of the branch pipe 31 is provided with a liquid outlet hole 32. An installation rack is arranged on the outer wall of the treatment box 1, and a liquid injection cylinder 33 penetrates through the installation rack. The liquid injection cylinder 33 is detachably connected with the installation rack, and the liquid injection end of the liquid injection cylinder 33 is inserted into the inside of the branch pipe 31. A liquid injection assembly is arranged in the inside of the liquid injection cylinder 33, and the liquid injection assembly is used for injecting the acidic solution in the inside of the liquid injection cylinder 33 into the inside of the branch pipe 31. When the sodium methoxide wastewater is treated, the sodium methoxide wastewater is input into the inside of the treatment box 1 through the water inlet pipe 4, and the acidic solution in the inside of the liquid injection cylinder 33 is injected into the inside of the branch pipe 31 through the liquid injection assembly. The acidic solution enters into the inside of the branch pipe 31 and is discharged from the liquid outlet hole 32 at the bottom of the branch pipe 31, and finally reacts with the sodium methoxide wastewater, so as to achieve the treatment purpose of the sodium methoxide wastewater. The detachable connection between the liquid injection cylinder 33 and the installation rack facilitates the installation of the liquid injection cylinder 33. When the acidic solution in the inside of the liquid injection cylinder 33 is used up, the liquid injection cylinder 33 is directly taken off from the limiting rack 34, and then the external acidic solution can be extracted again.

[0035] Please refer to Figure 6 and Figure 7 The liquid injection assembly comprises a piston 39 arranged in the inside of the liquid injection cylinder 33, and the piston 39 is slidably connected with the inner wall of the liquid injection cylinder 33. A threaded sleeve 38 is fixed at the end of the piston 39. A threaded rod 37 is threadedly connected with the end of the threaded sleeve 38 away from the piston 39. The threaded rod 37 penetrates through the end of the liquid injection cylinder 33 and is rotatably connected with the end of the liquid injection cylinder 33. A third gear 35 is fixed at the end of the threaded rod 37. The end of the rotating rod 10 is fixed with an incomplete gear 36 capable of engaging with the third gear 35. When the sodium methoxide wastewater is treated, the motor 6 is started to drive the rotating rod 10 to rotate, and the rotating rod 10 drives the stirring rod 9 to rotate, so as to stir the sodium methoxide wastewater through the stirring rod 9, thereby improving the contact area between the sodium methoxide wastewater and the reaction liquid, and further ensuring the neutralization effect of the sodium methoxide wastewater. When the rotating rod 10 rotates, the incomplete gear 36 also rotates. When the incomplete gear 36 rotates to a certain extent, the incomplete gear 36 engages with the third gear 35 to drive the threaded rod 37 to rotate by a certain angle. When the threaded rod 37 rotates, the piston 39 moves in the inside of the liquid injection cylinder 33 through the threaded connection with the threaded sleeve 38. The piston 39 extrudes the acidic solution in the inside of the liquid injection cylinder 33, so that the acidic solution can be intermittently injected into the inside of the branch pipe 31. In combination with the continuous mixing of the stirring rod 9, the uniform and efficient acid-base reaction can be ensured, the waste of acidic reagent can be reduced, and the stability and economy of the neutralization process can be improved.

[0036] Please refer to Figure 7A slider 311 is fixed to the outside of the threaded sleeve 38, and a slide groove 310 adapted to the slider 311 is provided on the inner wall of the liquid injection cylinder 33. The end of the slider 311 is located inside the slide groove 310 and is slidably connected to the slide groove 310; When the threaded sleeve 38 moves, it drives the slider 311 to move inside the slide groove 310. The slide groove 310 limits the threaded sleeve 38 through the slider 311, avoiding the phenomenon that the threaded sleeve 38 is driven by the rotation of the threaded rod 37, thereby ensuring the stability of the threaded sleeve 38 when moving.

[0037] Working principle: when the device is used for treating sodium methoxide wastewater, the sodium methoxide wastewater is input into the treatment box 1 through the water inlet pipe 4, the motor 6 is started, the rotating rod 10 is driven to rotate by the motor 6, the stirring rod 9 is driven to rotate by the rotating rod 10, and the sodium methoxide wastewater is stirred by the stirring rod 9. The rotating rod 10 also drives the incomplete gear 36 to rotate at the same time, when the incomplete gear 36 rotates to a certain extent, the incomplete gear 36 meshes with the third gear 35 to drive the threaded rod 37 to rotate to a certain angle. The threaded rod 37 rotates at the same time and drives the piston 39 to move in the liquid injection cylinder 33 through the threaded connection with the threaded sleeve 38. The piston 39 extrudes the acidic solution in the liquid injection cylinder 33, so that the acidic solution can enter the branch pipe 31 intermittently. The acidic solution enters the branch pipe 31 and is discharged from the liquid outlet hole 32 at the bottom of the branch pipe 31. Finally, it reacts with the sodium methoxide wastewater, and cooperates with the continuous mixing of the stirring rod 9, which can not only ensure the uniform and efficient acid-base reaction, but also reduce the waste of acidic reagent, improve the stability and economy of the neutralization process. In addition, the rotating rod 10 also drives the extrusion block 29 to rotate during rotation. The extrusion block 29 rotates and periodically extrudes the baffle 28. When the extrusion block 29 extrudes the baffle 28, the baffle 28 drives the tooth plate 27 to move downward. When the extrusion block 29 no longer extrudes the baffle 28, the baffle 28 automatically resets, thereby driving the tooth plate 27 to move upward. This cycle makes the tooth plate 27 move up and down continuously. The tooth plate 27 moves up and down and drives the transmission rod 25 to rotate reciprocally through the meshing with the second gear 26. The transmission rod 25 reciprocally rotates and drives the first gear 23 to reciprocally rotate. The first gear 23 drives the first rotating disc 7 to swing reciprocally through the meshing with the gear ring 22. The first rotating disc 7 drives the arc-shaped mesh cylinder 11 to swing reciprocally, thereby preventing salt from accumulating at the bottom of the arc-shaped mesh cylinder 11, ensuring smooth flow of wastewater, and ensuring the treatment efficiency of the sodium methoxide wastewater. When the sodium methoxide wastewater treatment is completed, the baffle 28 is pressed downward by manual operation, the baffle 28 drives the tooth plate 27 to move downward continuously, the tooth plate 27 meshes with the second gear 26 to drive the transmission rod 25 to rotate, the transmission rod 25 drives the first gear 23 to rotate, the first gear 23 meshes with the gear ring 22 to drive the first rotating disc 7 to rotate, until the arc-shaped mesh cylinder 11 is turned over 180°, that is, the opening at the top of the arc-shaped mesh cylinder 11 faces downward. Then the staff can inject clean water into the treatment box 1 through the water inlet pipe 4. Under the scouring of the clean water, the salt impurities adsorbed at the bottom of the arc-shaped mesh cylinder 11 automatically fall to the bottom of the treatment box 1, thereby cleaning the arc-shaped mesh cylinder 11. When the arc-shaped mesh cylinder 11 is turned over 180°, the end of the pin rod 213 automatically enters the pin slot 212 on the side wall of the slide rod 210. The pin rod 213 fixes the slide rod 210 through the pin slot 212, effectively ensuring the stability of the baffle 28, thereby improving the stability of the arc-shaped mesh cylinder 11 during the washing process.

[0038] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
