For ordinary skilled persons in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.
[0020] As Figure 1 shown, the utility model provides a screw speed regulating type pipeline mixer, including mixer body 3, mixer body 3 is installed between inlet pipe 1 and outlet pipe 2, and inlet pipe 1 and outlet pipe 2 are all installed through flange plate 9 and other components of pipeline, and the mixer still includes mixing assembly, dosing assembly and power assembly, and the dosing assembly is connected with automatic control box, and the output end of automatic control box is connected with power assembly.
[0021] The mixing assembly includes turbine 4 arranged inside the mixer body 3, the turbine 4 is arranged perpendicularly to the inner side wall of the mixer body 1, the diameter of the turbine 4 is slightly smaller than the inner diameter of the mixer body 1, a rotating shaft is arranged in the center of the mixer body 1, the center of the turbine 4 is sleeved on the rotating shaft, the water thrust generated by the input water flow forms a vortex to drive the impeller turbine 4 to rotate, which makes up the expected water head loss caused by the turbine 4 and the bearing and reduces energy consumption, and the mixing assembly further includes spiral blade 10, which is arranged inside the outlet pipe 2 and plays a role in dividing, rotating and converting fluid to promote fluid mixing.
[0022] The dosing assembly includes coagulant dosing pipe 301 and detection device, the coagulant dosing pipe 301 is perpendicular to the rotating direction of the turbine 4, the detection device includes flowmeter 6 and temperature transmitter 7, the flowmeter 6 is arranged at the junction of the inlet pipe 1 and the mixer body 3, and the temperature transmitter 7 is arranged in the inlet pipe 1, and the flowmeter 6 and the temperature transmitter 7 are connected with the automatic control box.
[0023] The power assembly includes motor 5 and electric control valve 8, the output end of the motor 5 is connected with the rotating shaft in the center of the turbine 4, and the electric control valve 8 is arranged in the coagulant dosing pipe 301 ， The motor 5 and the electric control valve 8 are connected with the automatic control box.
[0024] AsFigure 2 The flow meter 6 and the temperature transmitter 7 are connected to the automatic control box, and the measured water inflow and water temperature data are transmitted to the automatic control box. The output end of the automatic control box is connected to the motor 5 and the electric control valve 8. The rotation speed of the turbine 4 is controlled by the motor 5, and the opening angle of the electric control valve 8 controls the amount of coagulant, so as to improve the coagulation effect.
[0025] In normal operation, the raw water enters the mixer through the water inlet pipe 1. The water temperature is measured by the temperature transmitter 7, and the water inflow is measured by the flow meter 6. The measured data is transmitted to the automatic control box. According to the engineering consideration, the mixing process is to stir the water body to generate vortex or water flow velocity difference. Generally, the G value is controlled at 700-1000 s -1 , because G = (γh / μT) ^ 0.5. The water temperature directly affects the dynamic viscosity of water. By adjusting the residence time of water flow in the mixer, that is, by adjusting the rotation speed of the turbine 4, the velocity gradient is controlled to make the coagulation effect best. According to the flow measured by the flow meter 6, the opening angle of the electric control valve 8 on the coagulant feeding pipe 301 is adjusted, so as to control the amount of coagulant, so as to make the coagulation effect best. The spiral blade 10 which can be twisted left and right is arranged in the water outlet pipe 2. The spiral blade 10 plays a role of dividing, rotating and converting the fluid, and promotes the mixing of the fluid.
[0026] In order to make the impurity particles or the impurities and the coagulant flocculate, one necessary condition is the mutual collision of particles. The driving force for promoting the mutual collision of particles in water mainly comes from "heterogeneous flocculation" and "homogeneous flocculation". The water temperature directly affects the dynamic viscosity of water. When the water temperature rises, the dynamic viscosity of water will decrease. When the water temperature decreases, the dynamic viscosity will increase. This is because there is hydrogen bond and other interaction forces between water molecules. At low temperature, the thermal motion of water molecules is weak, and the hydrogen bond and other interaction forces between molecules dominate, making the relative motion between water molecules difficult. When the water temperature rises, the water molecules obtain more energy, and the thermal motion intensifies, so that part of the interaction force between molecules can be overcome, and the relative motion between molecules becomes easy. Therefore, the "heterogeneous flocculation" caused by Brownian motion is proportional to the water temperature. The "homogeneous flocculation" caused by the collision of particles in water body movement is mainly affected by the velocity gradient G. The stirring intensity is calculated according to the velocity gradient. The output power of the motor is changed by adjusting the frequency converter of the motor. The rotation speed of the motor is proportional to the frequency of the power supply. When the frequency of the power supply increases, the rotation speed of the magnetic field of the motor increases, and the rotation speed of the motor rotor also increases, so that the rotation speed of the turbine increases. When the water temperature decreases, the output power of the motor is increased, the rotation speed of the motor is increased, the collision of particles is increased, the coagulant is uniformly dispersed in water, the coagulant is quickly hydrolyzed, mixed and the particles are destabilized. When the water temperature rises, the output power of the motor is reduced, the rotation speed of the motor is reduced, and the waste of energy is avoided.
[0027] The water molecules pass through the residence time of the water flow in the mixer, i.e. by adjusting the rotating speed of the turbine 4, the velocity gradient is controlled, according to the flow measured by the flow meter 6, the opening angle of the electric control valve 8 on the coagulant feeding pipe 301 is adjusted, thus the coagulant feeding quantity is controlled, the coagulation effect is best, the spiral blade 10 which can be twisted left and right is arranged in the outlet pipe 2, the spiral blade 10 plays the role of dividing, rotating and converting to the fluid, the fluid mixing is promoted, at the same time the particles entering the outlet pipe enter the flocculation stage, the stirring of the spiral blade is beneficial to the collision and gathering of the particles.

Any equivalent change and improvement made according to the application range of the utility model should still belong to the patent coverage range of the utility model.
