Description

Technical Field

[0001] The utility model relates to the technical field of drug dosing for sewage treatment, and more specifically, to a drug dosing device for sewage treatment. Background Art

[0002] In the existing technology, the dosing device for sewage treatment often needs to use a large amount of chemicals to treat pollutants in the sewage during operation. Due to the large amount of liquid medicine added, if the liquid medicine is added continuously for a long time without effective mixing, it may cause the liquid medicine to form a sedimentation layer or chromatography in the container. This phenomenon will not only reduce the mixing effect of the liquid medicine, but also may cause the agent to fail to fully react with the pollutants in the sewage, thereby affecting the overall effect and efficiency of sewage treatment.

[0003] The occurrence of sedimentation layers or chromatography will cause the active ingredients of the agent to be not evenly distributed throughout the sewage system, resulting in excessive concentrations in some areas and too low concentrations in other areas. This uneven distribution of agents will reduce the effect of sewage treatment and may result in the failure to effectively remove certain pollutants, affecting the quality of sewage treatment.

[0030] In this embodiment, the medicine liquid is first introduced into the outer shell 1 through the filling pipe 10. When it needs to be circulated and mixed after being placed for a long time, the water pump 4 is started to transport the medicine liquid at the lower end to the upper end to complete the mixing process. When it is necessary to adjust the fixed mixing flow resistance according to different situations, first, by rotating the synchronous sleeve 11, since the two threaded disks 7 are respectively connected to the synchronous sleeve 11 by reverse threads, and the two ends of the synchronous sleeve 11 are respectively attached to the fixed disk 13, the two threaded disks 7 can be driven to move in opposite directions, move away from or approach synchronously, and the compensation tube 6 compensates for its expansion and contraction.

The elastic strip 9 is in a state of being attached to the inner wall of the compensation tube 6, thereby completing the resistance adjustment.

[0032] More specifically, after the mixing of the medicine liquid is completed, the wastewater is passed into the discharge water through the feed pipe 22, and then the spiral blade 21 is driven to rotate by the action of the motor 19, and then the medicine liquid and the wastewater are stirred and mixed synchronously along the discharge pipe 18, and then discharged into the next equipment, thereby completing the dosing process.

[0033] In summary, when the overall equipment is in use or running: first, the medicine liquid is introduced into the outer shell 1 through the filling pipe 10. When it needs to be circulated and mixed after being placed for a long time, the water pump 4 is started to transport the medicine liquid at the lower end to the upper end to complete the mixing process.

Multiple elastic strips 9 will move accordingly. When the elastic strip 9 is stretched, the elastic strip 9 will move toward the direction of the axis, thereby increasing the flow resistance and then reducing the flow rate. When the flow resistance needs to be reduced, the two are close to make the elastic strip 9 rebound, and the elastic strip 9 is in a state of being attached to the inner wall of the compensation tube 6, thereby completing the resistance adjustment.
