Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a wastewater treatment dosing system. Background Technology
[0002] In industrial wastewater treatment, chemical dosing systems are commonly used to add chemicals to adjust water quality parameters (such as pH, turbidity, and conductivity) and inhibit corrosion and scaling. Traditional dosing systems often employ fixed filtration structures and static mixing methods, which suffer from problems such as uneven chemical mixing, easy pipe clogging, and inconvenient filtration cleaning. Especially in the treatment of high-temperature or high-turbidity wastewater, insufficient chemical dissolution and impurity accumulation can affect treatment efficiency and even damage equipment. Furthermore, existing systems often lack the ability to monitor and control multiple parameters in real time, making it difficult to achieve precise dosing and system operation optimization.

[0017] like Figure 1 This is a schematic diagram of the structure of this utility model, a wastewater treatment dosing system, including a water storage tank 1, a heat exchanger 2, a circulating pump 3, a dosing tank 4, a first pipeline 5, a second pipeline 6, a third pipeline 7, and a fourth pipeline 8. The first pipeline 5, second pipeline 6, third pipeline 7, and fourth pipeline 8 are all used for liquid circulation. The output end of the water storage tank 1 is connected to the input end of the circulating pump 3 through the first pipeline 5. The output end of the circulating pump 3 is connected to the input end of the heat exchanger 2 through the second pipeline 6. The output end of the heat exchanger 2 is connected to the input end of the water storage tank 1 through the third pipeline 7. The third pipeline 7 and the second pipeline 6 are connected through the fourth pipeline 8. The fourth pipeline 8 is connected to the dosing tank 4 through a syringe 9. This system integrates circulating heating and dosing, improving treatment efficiency and system integration. The heat exchanger 2 and the circulating pump 3 work together to maintain stable water temperature and avoid affecting the treatment effect due to temperature fluctuations.
[0018] like Figure 1 As shown, the fourth pipeline 8 is sequentially equipped with a fouling thermal resistance probe 81, a corrosion test probe 82, a pH probe 83, a turbidity probe 84, an ORP probe 85, a conductivity probe 86, a sampling valve 87, and a Y-type filter 88.

The Y-type filter 88 and the drain pipe 71 further ensure the smooth flow of the pipeline. The precipitates are discharged in time through the drain pipe 71 to maintain the stable operation of the system.
[0020] The dosing tank 4 includes a lid 41, a body 42, a stirring mechanism 43, a centrifugal transmission mechanism 44, and a filtration mechanism 45.

The stirring mechanism 43 includes a stirring shaft 431. The bottom of the body 42 has a drug outlet. The lid 41 has at least one dosing port and at least one replenishment port. Both the dosing port and the replenishment port are connected to the mixing chamber 421. like Figure 2As shown, the filtration mechanism 45 includes a fixed base 451, a filter screen 452, and a sliding seat 453. The fixed base 451 is fixedly connected to the barrel 42. The filter screen 452 has a frustum-shaped structure.

The sliding seat 453 is slidably connected to the stirring shaft 431 and can slide up and down along the axial direction of the stirring shaft 431. The sliding seat 453 of the filtration mechanism 45 is connected to the stirring shaft 431 of the stirring mechanism 43 via a centrifugal transmission mechanism 44. The linkage design between the filtration mechanism 45 and the stirring mechanism 43 reduces the frequency of manual cleaning, realizes dynamic filtration and automatic impurity removal, reduces the risk of clogging, and facilitates cleaning. When the stirring shaft 431 is stationary, the sliding seat 453 is located above the fixed seat 451; When the stirring shaft 431 rotates, the sliding seat 453 is located below the fixed seat 451.

The motor 432 is fixedly connected to the barrel 42, and the motor 432 is located outside the barrel 42. The output end of the motor 432 is connected to the stirring shaft 431 through a coupling. The stirring blade 433 is fixedly connected to the stirring shaft 431. The stirring blade 433 is located in the mixing chamber 421 of the barrel 42, and the stirring blade 433 is located below the centrifugal transmission mechanism 44. The stirring and filtration are linked by direct drive of the motor 432, thereby improving the mixing and filtration efficiency.
[0022] like Figure 2 As shown, the centrifugal transmission mechanism 44 includes a return spring 441, a first connecting rod 442, and a second connecting rod 443. The return spring 441 is located above the sliding seat 453. One end of the return spring 441 is connected to the stirring shaft 431, and the other end is connected to the sliding seat 453. The first end of the first connecting rod 442 is rotatably connected to the sliding seat 453, the tail end of the first connecting rod 442 is rotatably connected to the first end of the second connecting rod 443, and the middle part of the second connecting rod 443 is rotatably connected to the stirring shaft 431. By adopting the linkage structure of the return spring 441, the first connecting rod 442, and the second connecting rod 443, the mechanical linkage and automatic reset of stirring and filtering can be realized. The rotational connection of the centrifugal transmission mechanism 44 can be a pin connection.
[0023] like Figure 2 As shown, a stirring rod 444 is arranged at the tail end of the second connecting rod 443. The dynamic structure of the stirring rod 444 helps to form turbulence. Through the linkage between the stirring mechanism 43 and the centrifugal transmission mechanism 44, the agent can be fully dissolved and uniformly mixed, avoiding local concentrations that are too high or too low.
[0024] like Figure 2As shown, a groove is provided on the fixing seat 451, and the groove of the fixing seat 451 and the barrel wall enclose a miscellaneous storage cavity 4511. The barrel 42 has a through hole 422 that communicates with the storage cavity 4511. A sealing seat 423 connected to the barrel 42 is arranged in the through hole 422. Through the structure of the storage cavity 4511 and the openable through hole 422, centralized cleaning and sealing protection can be achieved.
[0025] The connection method in this application may be threaded connection, welding, bonding, etc.
[0026] Working process: Wastewater is pumped from storage tank 1 into heat exchanger 2 via circulation pump 3 for temperature regulation; the regulated wastewater is partially returned to storage tank via third pipeline 7, and partially enters the dosing circuit via fourth pipeline 8; on the fourth pipeline, multiple sensors monitor water quality parameters in real time, and the control unit adjusts the dosing amount based on the data; the reagent in dosing tank 4 is injected into the fourth pipeline via syringe 9, mixes with the wastewater, and then enters the main circulation; inside the dosing tank, motor 432 drives stirring shaft 431 to rotate, driving stirring blade 433 to mix the reagent; during stirring, centrifugal transmission mechanism 44 pushes sliding seat 453 downward, and filter screen 452 forms an inverted cone structure, which traps impurities; when stirring stops, return spring 441 pushes sliding seat 453 back to its original position, and filter screen 452 forms a positive cone structure (e.g., ...). Figure 2 As shown, under the elastic vibration, impurities fall into the impurity storage chamber 4511, automatically removing impurities and increasing the service life of the filter screen 452; the accumulated impurities in the impurity storage chamber are periodically cleaned through the through hole 422 to maintain the filtration effect.
