Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a drug-dosing sewage treatment device. Background Art

[0002] With environmental protection receiving increasing attention, sewage treatment has become a crucial task. Sewage treatment is the process of removing harmful substances from sewage through various physical, chemical, and biological methods to ensure that it meets discharge standards or water quality requirements for reuse.

[0003] Dosing is a common treatment method in sewage treatment. By adding specific chemicals to sewage, reactions such as precipitation, oxidation, and reduction of harmful substances can be accelerated, improving the efficiency and effectiveness of sewage treatment. For example, flocculants can agglomerate suspended matter into larger particles, facilitating their removal. Disinfectants can kill bacteria and viruses in sewage, preventing the spread of disease.

[0004] However, traditional sewage treatment dosing equipment has numerous drawbacks. When it comes to uniform dispersion of chemicals, traditional equipment often struggles to achieve uniform distribution of the chemicals within the wastewater. Some equipment simply injects the chemicals directly into the sewage treatment tank, which can lead to localized accumulation and inadequate mixing with the wastewater, resulting in uneven dosing. This not only impacts the efficiency and quality of sewage treatment but can also result in chemical waste. Utility Model Content

[0005] (1) Technical issues

[0006] The purpose of the utility model is to provide a sewage treatment device with a dosing device, so as to solve the problem that traditional sewage treatment dosing equipment has deficiencies in terms of uniform dosing and dispersion.

The mounting plate is L-shaped and the upper end extends above the sewage treatment tank. A medicine storage box is fixedly provided on the upper end surface of the mounting plate, and a metering pump is connected to the bottom outlet of the storage medicine box. A rotating shaft is rotatably provided at the bottom of the mounting plate, and a centrifugal disk is fixedly provided at the bottom of the rotating shaft.

[0013] (3) Technical effects

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. This utility model utilizes a centrifugal disc and a horizontally movable mounting plate to evenly distribute the reagent into the sewage treatment tank. A metering pump delivers the reagent to the gap between the rotating shaft and the casing. Centrifugal force then ejects the reagent from the centrifugal disc. As the mounting plate moves horizontally, the reagent is evenly distributed across the sewage, preventing localized accumulation of the reagent.

[0016] 2. The storage tank is equipped with a stirring mechanism. Motor 3 drives shaft 2 and the threaded blades to rotate, which can prevent the precipitation and agglomeration of the medicine, ensuring the uniformity and effectiveness of the medicine. During the dosing process, high-quality medicine is always provided, further improving the dosing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment, as a preferred technical solution, a slide groove 10 is provided at the upper end of the sewage treatment tank 1, and the bottom of the mounting plate 2 is slidably matched with the slide groove 10. The driving mechanism is arranged inside the slide groove 10. The driving mechanism includes a screw rod 11 that is rotated inside the slide groove 10, and also includes a motor 12 fixed on the side of the sewage treatment tank 1 for driving the screw rod 11 to rotate. The screw rod 11 passes through the bottom of the mounting plate 2 and is threadedly connected to the mounting plate 2.

[0029] In this embodiment, as a preferred technical solution, the stirring mechanism includes a motor three 13 fixed to the upper end of the medicine storage box 3, and a driving shaft of the motor three 13 extends into the storage medicine box 3.

[0030] The working principle of the drug-dosing sewage treatment device of the present invention is as follows: the drug-dosing sewage treatment device mainly realizes the uniform addition of drugs in the sewage treatment tank 1 through the cooperation of components such as the drug storage box 3, the metering pump 4, the centrifugal disc 6 and the movable mounting plate 2. The drugs in the drug storage box 3 are quantitatively transported to the gap between the rotating shaft 5 and the sleeve 7 by the metering pump 4, and then thrown out from the centrifugal disc 6 under the action of centrifugal force. Since the upper end surface of the centrifugal disc 6 is provided with a downward slope from the center to the edge, the drugs can diffuse outward more smoothly. At the same time, the mounting plate 2 moves horizontally under the action of the driving mechanism, so that the drugs can be evenly distributed to different positions in the sewage treatment tank 1. The stirring mechanism in the drug storage box 3 ensures the uniformity of the drugs and prevents precipitation and agglomeration.

[0031] The working process of the utility model of a dosing sewage treatment device is as follows:

[0032] 1. Preparation: Check whether the medicine in the medicine storage box 3 is sufficient, start the stirring mechanism, and the motor 3 13 drives the rotating shaft 2 14 and the threaded blade 15 to rotate to stir the medicine to prevent precipitation.

[0033] 2. Dosing start: Start metering pump 4 to quantitatively deliver the medicine in storage tank 3 to pipe 9, and then into the gap between shaft 5 and sleeve 7. At the same time, start motor 8, driving shaft 5 and centrifugal disc 6 to rotate at high speed. Under the action of centrifugal force, the medicine is thrown out of centrifugal disc 6 and enters sewage treatment tank 1.

[0034] 3. Horizontal Dosing: Start motor 2 12, which drives screw 11 to rotate, causing mounting plate 2 to move horizontally within chute 10 at the upper end of sewage treatment tank 1. As mounting plate 2 moves, centrifugal disc 6 continuously and evenly disperses the agent to different locations in sewage treatment tank 1, achieving comprehensive dosing.

[0035] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto.
