[0028] The top of the stirring tank 1 is connected to the reaction tank 6 through a connecting pipe 5, a liquid adding device 7 is installed inside the connecting pipe 5, a pH detector 8 is installed on the right side of the liquid adding device 7 at the top of the connecting pipe 5, the liquid adding device 7 includes a paddle 71, the inner limit rotation of the connecting pipe 5 is connected to the paddle 71, the right end of the paddle 71 is connected to a turntable 72, the outer periphery of the turntable 72 is elastically connected to a contact block 73, a feed barrel 74 is fixedly installed above the turntable 72 at the top of the connecting pipe 5, and the feed barrel 74 is fixedly installed above the turntable 72 at the top of the connecting pipe 5. The bottom of the inner part of the feeding cylinder 74 is elastically slidably connected to the flow limiting rod 75, and the top of the flow limiting rod 75 is fixedly connected to the conical head 76. The top of the feeding cylinder 74 is slidably connected to the drop hopper 77. The bottom of the drop hopper 77 is provided with a round mouth, and the top of the conical head 76 extends to the inside of the drop hopper 77. The tip of the conical head 76 faces downward, and the diameter of the top is larger than the diameter of the round mouth at the bottom of the drop hopper 77. The top of the feeding cylinder 74 is connected to the neutralizing agent connecting pipe 9, so that the conical head 76 can be used to connect the neutralizing agent to the feed hopper 77. The round mouth is used to adjust the passing area at the bottom of the drop hopper 77. Metal blocks 78 are fixedly installed on the left and right ends of the drop hopper 77.

[0029] During use, the wastewater required and tested is passed into the mixing tank 1, and then the motor 3 is started, so that the motor 3 drives the suction cylinder 21 to rotate, and then drives the stirring blade 4 to rotate at the same time. During the rotation of the stirring blade 4, the wastewater inside the mixing tank 1 can be driven to swirl, so as to achieve stirring and mixing, and the flocculent and solid impurities inside the wastewater can be concentrated and moved to the center of the mixing tank 1 under the action of centripetal force, and then enter the suction cylinder 21 through the inlet 22 for accumulation, and then be collected and cleaned through the timed suction of the sewage outlet 27. Since the suction cylinder 21 is clamped with the sleeve 23, the sleeve 23 and the support rod 24 can also be driven to rotate. During the rotation, the design of the water inlet 25 on the rotationally symmetrical side of the support rod 24 can be used to collect wastewater from multiple places inside the mixing tank 1, and through suction The tube 26 converges into the top of the sleeve 23 and enters the reaction tank 6 through the connecting pipe 5. When the wastewater flows in the connecting pipe 5, the pH detector 8 installed on the top of the connecting pipe 5 can measure the pH value of the wastewater, and at the same time, it can drive the paddle 71 to rotate, and then drive the turntable 72 to rotate. During the rotation of the turntable 72, the contact block 73 on the outer periphery of the turntable 72 will move outward under the action of centrifugal force, and then touch the flow limiting rod 75 on the top, and intermittently push the flow limiting rod 75 to move upward. During the upward movement of the flow limiting rod 75, it can drive the conical head 76 to open the circular mouth at the bottom of the drop hopper 77, so that the agent inside the neutralizing agent connecting pipe 9 can flow downward through the drop hopper 77, and then enter the inside of the connecting pipe 5, and follow the wastewater into the inside of the reaction tank 6 for neutralization treatment;

[0030] According to the different wastewater flow rates inside the connecting pipe 5, the speeds at which the paddle 71 and the turntable 72 rotate will also be different. When the water flow rate is accelerated, the rotation speeds of the paddle 71 and the turntable 72 will also be accelerated, so that the contact block 73 is moved outward more by the centrifugal force, and the flow limiting rod 75 and the conical head 76 are pushed upward more, thereby increasing the passing area between the conical head 76 and the bottom of the hopper 77, thereby increasing the addition of the medicine. On the contrary, when the wastewater flow rate is reduced, the addition of the medicine will be reduced, thereby achieving The self-regulation of the reagent according to the wastewater flow rate is realized. At the same time, through the electrical connection between the pH detector 8 and the power supply circuit of the energized coil 79, the current inside the energized coil 79 can be adjusted according to the detection result of the pH detector 8, thereby changing the attraction of the metal block 78 to the magnetic force generated at the upper and lower ends of the energized coil 79 after power is turned on. The metal block 78 drives the drop hopper 77 to move up and down to change the passing area between the conical head 76 and the bottom of the drop hopper 77, thereby realizing the self-regulation of the reagent dosage according to the pH value.
