Technical Field

[0001] This utility model relates to the field of wastewater treatment dosing technology, specifically to an integrated wastewater treatment dosing device. Background Technology

[0002] In vast villages and scattered areas, there are no connected sewage treatment plants, and the sewage generated is dispersed, with relatively small overall volume, large fluctuations in water quality, and unstable discharge. Using traditional pipe networks would involve large-scale engineering projects, high investment, and difficulty in meeting the corresponding sewage treatment needs. In cities, sewage is mainly transported to sewage treatment plants through sewage pipelines for treatment. With social development and widespread urbanization...

[0003] The specification of an integrated wastewater treatment device in the prior art (publication number CN216236572U) mentions that it "includes an anaerobic reaction tank, an anoxic reaction tank, an aerobic reaction tank, a sedimentation reaction tank, a biological filter tank, and a disinfection tank connected in sequence. The anaerobic reaction tank is equipped with an anaerobic packing support frame and a first aeration pipe located below the anaerobic packing support frame. The anoxic reaction tank is equipped with a facultative anaerobic packing support frame and a second aeration pipe located below the facultative anaerobic packing support frame. The aerobic reaction tank is equipped with an aerobic packing support frame and a third aeration pipe located below the aerobic packing support frame. The sedimentation reaction tank is equipped with a sludge settling mechanism and a fourth aeration pipe located below the sludge settling mechanism. The biological filter tank is equipped with a biological filter media support frame and a fifth aeration pipe located below the biological filter media support frame." However, the existing wastewater treatment device contains particulate matter such as chemical residues, resulting in uneven mixing of the chemical solution and affecting its effectiveness, making it inefficient and impractical. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, an integrated wastewater treatment dosing device is provided to solve the problem that existing wastewater treatment devices contain particulate matter such as dregs, which leads to uneven mixing of the solution and affects the effectiveness of the solution, making them inefficient and impractical.

[0005] To achieve the above objectives, an integrated wastewater treatment dosing device is provided, comprising a dosing cylinder, a motor, and a filter structure. The upper part of the dosing cylinder is provided with a dosing chamber, and the motor is installed at the center of the upper end of the dosing chamber. The lower end of the motor is provided with a rotating shaft, and the middle rod of the rotating shaft passes through the center of the filter structure. The lower part of the dosing cylinder is provided with a lower output hopper, and the lower left and right sides of the lower output hopper are connected to side conveying pipes. The lower end of the lower output hopper is provided with a discharge pipe.

[0006] Furthermore, a first hopper and a second hopper are respectively provided on the left and right sides of the upper end face of the dosing chamber, and a return pipe is connected to the left side of the dosing chamber, and a water pump is installed on the upper part of the return pipe.

[0007] Furthermore, a middle connecting pipe and an upper connecting pipe are connected to the left side of the middle part of the dosing cylinder, and electromagnetic control valves are installed on the middle connecting pipe, the upper connecting pipe and the return pipe.

[0008] Furthermore, a first electromagnetic control valve is installed on the discharge pipe, and multiple sets of dosing diversion pipes are connected to the side delivery pipe, with a second electromagnetic control valve installed on each dosing diversion pipe.

[0009] Furthermore, an agitator is installed on the upper part of the rotating shaft, and the agitator is located in the upper space inside the dosing cylinder. Three sets of scrapers are installed in the middle of the rotating shaft, and the scrapers are located in the middle space inside the dosing cylinder.

[0012] 1. The side conveying pipes and dosing diversion pipes set on the left and right sides of the lower output hopper of this utility model can convey chemicals to the integrated sewage treatment structure separately. With multiple dosing diversion pipes, it is more convenient and practical to do chemicals separately.

[0013] 2. This utility model utilizes a motor to rotate a shaft, which drives a stirring paddle to stir the liquid medicine in the upper space of the dosing cylinder, making the medicine more evenly mixed. Then, three sets of scrapers scrape up the filter residue from each layer of the filter screen in the filter structure, facilitating continuous filtration of the residue and making the filtered liquid medicine finer. Finally, the liquid medicine is transported downwards by a spiral conveyor paddle, which is faster and more convenient.

[0014] 3. The filter structure of this utility model facilitates multi-layer filtration of the mixed medicine solution, filtering out medicine residue and other substances. Then, the remaining medicine residue and medicine solution are returned for further processing through the return pipe, middle connecting pipe, upper connecting pipe and water pump, making the medicine solution more uniform and delicate, and the medicine addition is also smooth and convenient.
