Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a dosing device for wastewater treatment that can quickly mix chemicals. Background Technology

[0002] In wastewater treatment, adding appropriate chemicals is a key step in achieving effective purification. Traditional methods of chemical dosing in wastewater treatment mostly rely on manual spreading. However, this method has several insurmountable drawbacks. Firstly, manual operation makes it difficult to ensure the uniformity of chemical distribution. During spreading, individual differences among operators and unavoidable human error can easily lead to uneven distribution of chemicals in the wastewater. Some areas may have excessively high concentrations, potentially triggering unnecessary chemical reactions, resulting in resource waste and new pollution risks. Conversely, some areas may have insufficient concentrations, failing to fully utilize the treatment effect and significantly reducing the quality of wastewater treatment. Secondly, manual spreading is extremely inefficient. Operators need to expend a significant amount of time and energy to complete the dosing work. Especially when treating large-scale wastewater, this inefficient method severely restricts the overall progress of wastewater treatment and increases costs. Therefore, a dosing device that facilitates rapid mixing and stirring is designed to improve the uniformity of the added materials and simultaneously enable rapid mixing, thereby increasing work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater treatment dosing device that can quickly mix materials, improve the uniformity of the added materials, and at the same time, quickly stir and mix them, thereby improving work efficiency.

[0021] like Figures 1-4 As shown, a rapid mixing dosing device for wastewater treatment includes a water tank 1, a sliding support 4, and a feeding mechanism 6. The sliding support 4 is connected to the sliding strip 3 and rack 2 on the side of the water tank 1 via sliding grooves 7 on both sides and a driving mechanism 5, respectively. The feeding mechanism 6 is provided on the upper part of the sliding support 4.

In these steps, the traditional method is to use manual methods. However, manual operation is relatively cumbersome, requiring the addition of agents and stirring and mixing. Based on this situation, a device that is easy to add agents and can quickly stir and mix has been designed.

Under the drive of the drive mechanism 5, it can move back and forth on the upper part of the water tank 1, thereby moving the upper feeding mechanism 6 to realize movable drug feeding and improve the uniformity of drug feeding. Furthermore, with the setting of the feeding mechanism 6, the drug can be pre-stored inside the feeding hopper 602, and the feeding hopper 602 is connected to the lower feeder 609 through the rotating tube 603. The material can fall by its own weight and overflow through the discharge port 608, and then the drug is introduced into the lower water tank 1 through the guide groove on the feeder 609.

[0024] It should be further explained that the lower part of the rotating tube 603 is provided with a stirring support 610, which can rotate based on the drive mechanism 5 to achieve stirring during the feeding process and improve the mixing efficiency.

[0026] It should be noted that the control valve 614 is designed to control the intermittent feeding of the rotating tube 603, opening it when necessary.

[0027] It should be further explained that, in order for the rotating tube 603 to rotate, bearings are provided at the connection points between the rotating tube 603 and the first fixed bracket 601 and the second fixed bracket 612.

The second drive motor and the second rotating shaft are provided on the other side of the sliding bracket 4. The first sprocket is provided on the upper part of the second rotating shaft, and the first sprocket is connected to the second sprocket 509 on the rotating tube 603 through the transmission chain 508 to form a transmission structure.

[0029] It should be noted that the drive mechanism 5 is provided with two drive groups, both located on both sides of the first fixed bracket 601, which can be driven simultaneously. The first rotating shaft 503 and the second rotating shaft can be connected to the side of the sliding bracket 4 through the bearing seat 504. The upper part of the first rotating shaft 503 is connected to the third gear 505 on the output shaft of the first drive motor 501 through the second gear 502 to form the first transmission structure. The other end of the first rotating shaft 503 is provided with a first gear 506, which passes through the rectangular opening of the first fixed bracket 601 and is connected to the rack 2. Driven by the first drive motor, the sliding bracket 4 can be moved, thereby realizing the movement of the entire device.
