Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a water treatment agent dosing device. Background Art

[0002] When treating sewage, flocculants are usually used to aggregate impurity particles and natural colloid particles in the sewage into large flocs for precipitation or floating, thereby purifying the sewage. During the drug delivery process, the dosage of the drug needs to be adjusted according to the water quality and flow rate of the sewage. Too much dosage may lead to drug waste or secondary pollution, while too little dosage will not achieve the expected effect. However, when using existing drug delivery equipment, it is difficult to achieve precise control of the dosage of the drug, resulting in untimely and inaccurate regulation of the drug delivery process, affecting the effective treatment of sewage. In addition, the drug delivery position of the existing drug delivery equipment is fixed, which cannot make the drug diffuse quickly and evenly in the sewage, and the dissolution rate is slow.

The umbrella-shaped diverter, the reaction tank and the turntable are coaxially arranged, and an annular water diversion chamber is coaxially provided at the upper end of the outer wall of the reaction tank. A water diversion hole is provided between the reaction tank and the annular water diversion chamber, and the water diversion holes are distributed in a circular array around the reaction tank, and the annular water diversion chamber is connected to the water supply pipe.

[0005] Among them, the self-adjusting medicine delivery equipment includes a medicine storage chamber, a rotating chamber, a medicine dosing turntable and a medicine dosing shaft. The medicine storage chamber is arranged at the upper end of the rotating chamber. The rotating chamber is cylindrical. The medicine dosing shaft rotates coaxially and passes through the rotating chamber. The medicine dosing shaft is connected to the hydraulic drive component. The medicine dosing turntable is rotated in the rotating chamber. The circumferential side wall of the medicine dosing turntable slides and fits with the inner wall of the rotating chamber. The medicine dosing turntable is coaxially fixed to the medicine dosing shaft. The side wall of the medicine dosing turntable is radially provided with a medicine dosing groove. The medicine dosing groove is distributed in a circular array around the axis of the medicine dosing turntable. The medicine dosing hole is provided on the bottom wall of the rotating chamber. A strip-shaped medicine leakage hole is provided between the rotating chamber and the medicine storage chamber.

[0006] When sewage flows through the hydraulic drive component, it drives the dosing shaft to rotate, and the dosing shaft drives the dosing turntable to rotate. When the dosing turntable rotates, it drives multiple dosing troughs to rotate in sequence to the bottom of the strip leakage hole. The medicine in the medicine storage chamber falls into the dosing trough through the strip leakage hole. When the dosing trough rotates from under the strip leakage hole, the inner wall of the rotating cavity blocks the dosing trough to prevent the medicine inside the dosing trough from leaking. When the dosing trough rotates to the dosing hole, the medicine inside the dosing trough automatically falls into the reaction tank under the action of gravity. The greater the sewage flow rate, the faster the flow rate, and then the faster the hydraulic drive component drives the dosing shaft to rotate, the faster the dosing turntable rotates, and the faster the medicine dosing acceleration.

[0007] As a further improvement of this solution, an adjusting piston is slidingly provided in the medicine dosing trough, a spring is provided between the adjusting piston and the medicine dosing trough, a fixed magnet is provided in the adjusting piston, and an electromagnet ring is provided on the central axis of the medicine dosing turntable.

The reciprocating screw is fixed, so that the threaded slider slides back and forth along the reciprocating screw. The threaded slider drives the sliding shaft to slide back and forth along the central axis and the support column.

[0010] Furthermore, an auxiliary blade is slidably provided on the stirring blade, and the auxiliary blade is slidably arranged along the length direction of the stirring blade. Push-pull hinge rods are distributed in a circular array on the side wall of the turntable, one end of the push-pull hinge rod is hingedly connected to the turntable, and the other end of the push-pull hinge rod is hingedly connected to the auxiliary blade.

[0011] When the sliding shaft drives the stirring blade to move up and down, the stirring blade drives the auxiliary blade to move up and down closer to or away from the turntable, thereby pushing and pulling the hinge rod to push the auxiliary blade to slide back and forth along the length direction of the stirring blade. The horizontal reciprocating motion of the auxiliary blade generates pulsed shear force and disturbance, and the medicine is periodically squeezed and stretched in the horizontal direction. Combined with the rotation and up and down movement of the stirring blade, multi-directional mixing and stirring is achieved.

[0022] 1. When sewage flows through the hydraulic drive component, it drives the dosing shaft to rotate, driving the automatic dosing of the medicine. The amount of medicine added is automatically adjusted according to the flow rate of sewage.

By adjusting the dosage speed and the single dosage, the dosage of the agent is precisely controlled, and the dosage of the agent is adjusted in a timely and accurate manner during the dosing process.

[0024] 3.

[0026] 5. When the sliding shaft drives the stirring blade to move up and down, the stirring blade drives the auxiliary blade to move up and down closer to or away from the turntable, thereby pushing and pulling the hinge rod to push the auxiliary blade to slide back and forth along the length direction of the stirring blade. The horizontal reciprocating motion of the auxiliary blade generates pulsed shear force and disturbance, and the agent is periodically squeezed and stretched in the horizontal direction.

[0049] The water inlet pipe 38 is connected to a water pump 43, and a liquid level sensor 44 is provided in the reaction tank 1.

The liquid level sensor 44, the water pump 43, and the solenoid valve 45 are electrically connected to the controller 35 respectively.

[0050] like Figure 1 、 Figure 2 、 Figure 6-Figure 9 As shown, the multi-directional stirring mechanism 8 includes a central shaft 25, a reciprocating screw 26, a sliding shaft 27 and a stirring blade 28. The central shaft 25 is fixedly installed on the central axis portion of the bottom wall of the reaction tank 1, and the support column 11 is distributed in a circular array around the central shaft 25. The reciprocating screw 26 is fixedly installed on the upper end of the support column 11. The reciprocating screw 26 is engaged with a threaded slider 29.

[0051] An auxiliary blade 32 is slidingly provided on the stirring blade 28, and the auxiliary blade 32 is slidingly provided along the length direction of the stirring blade 28.

[0052] When in use, the medicine is stored in the medicine storage chamber 15, the water pump 43 and the drive motor 39 are started, and the sewage is sent into the hydraulic drive chamber 36 through the water inlet pipe 38 by the water pump 43, and then sent into the annular water distribution chamber 13 through the water supply pipe 4, and the sewage drives the water wheel 37 to rotate, the water wheel 37 drives the medicine dosing shaft 18 to rotate, and the medicine dosing shaft 18 drives the medicine dosing turntable 17 to rotate. When the medicine dosing turntable 17 rotates, it drives multiple medicine dosing troughs 19 to rotate to the bottom of the strip medicine leakage hole 20 in turn. The medicine in the medicine storage chamber 15 falls into the medicine dosing trough 19 through the strip medicine leakage hole 20. When the medicine dosing trough 19 is turned away from the bottom of the strip medicine leakage hole 20, the inner wall of the rotating chamber 16 blocks the medicine dosing trough 19 to prevent the medicine inside the medicine dosing trough 19 from leaking. When the medicine dosing trough 19 rotates to the medicine dosing hole 6, the medicine dosing trough The medicine inside 19 automatically falls into the reaction tank 1 under the action of gravity. The greater the sewage flow, the faster the flow rate, and then the faster the hydraulic drive component 3 drives the dosing shaft 18 to rotate, the faster the dosing turntable 17 rotates, the faster the medicine dosing acceleration, and the more medicine is dosed. During the water delivery process, the water quality detection sensor module monitors the sewage water quality and feeds back to the controller 35. The controller 35 adjusts the magnetic force of the electromagnet ring 24 according to the water quality of the sewage. The worse the sewage water quality, the greater the magnetic force of the electromagnet ring 24, and the greater the magnetic attraction of the electromagnet ring 24 to the fixed magnet 23. The fixed magnet 23 drives the regulating piston 21 to overcome the elastic force of the spring 22 and slide more toward the inside of the dosing slot 19, so that the dosing space becomes larger and the single dosing amount increases. Through the dosing speed and single dosing The amount of medicine can be adjusted to achieve precise control of the dosage, and the dosage of the medicine can be adjusted in time and accurately during the dosage process. The driving motor 39 drives the driving shaft 40 to rotate, and the driving shaft 40 drives the driven bevel gear 42 to rotate through the active bevel gear 41. The driven bevel gear 42 drives the umbrella-shaped diverter 10 and the turntable 12 to rotate synchronously through multiple support columns 11. The medicine falls to the surface of the umbrella-shaped diverter 10 through the dosing hole 6, and at the same time, the sewage is sprayed to the surface of the umbrella-shaped diverter 10 through the water diversion hole 14. The sprayed sewage and the medicine are pre-mixed on the surface of the umbrella-shaped diverter 10. At the same time, the rotating umbrella-shaped diverter 10 evenly disperses the pre-mixed sewage and medicine into the reaction tank 1. When the multiple support columns 11 rotate, the sliding shaft 27 is driven to rotate synchronously around the central axis 25. The sliding shaft 27 rotates When the mixing blade 28 is moved up and down, the mixing blade 28 drives the auxiliary blade 32 to move up and down, close to or away from the turntable 12, thereby pushing and pulling the hinge rod 33 to push the auxiliary blade 32 to slide back and forth along the length direction of the mixing blade 28, thereby achieving multi-directional mixing. The mixing blade 28 not only provides a shear force in the circumferential direction to cause the material to diffuse radially, but also moves up and down to introduce axial convection, forming a spiral mixing trajectory.The reagent undergoes radial dispersion, axial circulation, and circumferential shearing in the container simultaneously. The horizontal reciprocating motion of the auxiliary blade 32 generates pulsed shear force and disturbance. The reagent is periodically squeezed and stretched in the horizontal direction. In conjunction with the rotation and up and down motion of the stirring blade 28, multi-directional mixing and stirring are achieved, making the stirring more complete and efficient. The liquid level sensor 44 monitors the liquid level in the reaction tank 1 in real time. When the sewage in the reaction tank 1 reaches the preset liquid level, the liquid level sensor 44 sends a signal to the controller 35. The controller 35 controls the water pump 43 to stop pumping sewage. The drive motor 39 drives the premixing mechanism 7 and the multi-directional stirring mechanism 8 to rotate for a period of time and then stops, allowing the sewage and the reagent to fully react and precipitate. After a period of time, the drain valve 48 is opened to discharge the reacted sewage from the reaction tank 1 for filtration. After the discharge is completed, the drain valve 48 is closed again and the above operation is repeated.
