Description

Technical Field

[0001] This utility model relates to the technical field of water purification systems, and specifically to a chemical dosing device for a water purification system. Background Technology

[0002] The core of a waterworks is the water purification system, which transforms natural water sources (such as surface water and groundwater) into drinking water that meets the needs of daily life and production. The treated tap water is then transported to various areas of the city through a pipeline system to meet the water needs of different users, including residents, businesses, and industries. Some waterworks also undertake the task of treating sewage from surrounding areas, treating domestic sewage and industrial wastewater to meet discharge standards before being released, in order to protect the environment and water resources. During water treatment in the water purification system, chemicals need to be added to the purification tank at regular intervals and in measured quantities through a dosing device to achieve water purification.

[0003] Most existing water purification system dosing devices (such as Chinese patents CN213977022U and CN221906913U) can only dosing of chemicals for a single purification tank and cannot be used for multiple purification tanks, resulting in low treatment efficiency. At the same time, most of these dosing devices do not have a stirring mechanism, making it difficult to stir the chemical solution in the tank, which can easily lead to chemical adhesion and blockage of the dosing pipes.

[0033] In this embodiment, the water purification system dosing device also includes a support frame 80, which includes a lower plate 81, an upper plate 82, and a vertical plate 83. The lower plate 81 is connected to the inner surface of the annular purification tank group 2, the upper plate 82 is arranged parallel above the lower plate 81, the vertical plate 83 is supported between the upper plate 82 and the lower plate 81, the lower end of the medicine tank 10 abuts against the upper plate 82, the external gear ring 41 is rotatably mounted on the upper plate 82 through a bearing, and the drive motor 71 is mounted on the lower plate 81.

[0034] To facilitate the extraction of medicine from the inner tube 21, in this embodiment, the lower end of the inner tube 21 is provided with a medicine extraction head 214. Both the inner tube 21 and the medicine extraction head 214 are fixed on the bottom wall of the medicine box 10. The medicine extraction head 214 is provided with a lateral medicine extraction port 215 that communicates with the inner tube 21.

[0035] To prevent foreign objects from falling into the purification tank 1, in this embodiment, all purification tanks 1 are equipped with a tank cover plate 3. The middle part of the tank cover plate 3 is equipped with a medicine receiving pipe 4 that is connected to the purification tank 1. The upper end of the medicine receiving pipe 4 is equipped with a funnel-shaped opening 5 that opens upward and outward. The lower end of the medicine adding pipe 40 is bent vertically downward and aligned with the funnel-shaped opening 5.

[0036] In this embodiment, the annular purification pool group 2 is an annular groove. Several partitions are provided in the annular groove, and the space between adjacent partitions forms a single arc-shaped purification pool 1. At the same time, the outer surface of the annular groove is also connected to the support legs for supporting the annular purification pool group 2 on the ground.

[0037] It should be noted that, in order to facilitate the control of the rotation angle of the outer gear ring 41, when it stops, the dosing tank 50 can be aligned with the outer tube 22, and / or the dosing tube 40 can be aligned with the horn mouth 5. The drive motor 71 can be a servo motor to monitor the rotation angle. Detection marks can be set on the drive gear 72 or the outer gear ring 41, and detection can be performed by means of position sensors, etc., to achieve angle control.

[0038] The specific working process of this utility model is described below.

[0039] In use, first start the drive motor to rotate the outer gear ring until the dosing tank is aligned with the lower opening of the outer tube, and close the dosing control valve. Then, turn on the suction pump and suction control valve to discharge the liquid medicine in the tank into the dosing tank. When the liquid level sensor in the dosing tank is triggered, turn off the suction pump and suction control valve, and start the drive motor again to rotate the outer gear ring until the lower end of the dosing tube is aligned with the flared opening of the dosing tube of one of the purification tanks. Then, turn on the dosing control valve to discharge the liquid medicine in the dosing tank into that purification tank, thus achieving dosing for a single purification tank. After the dosing for that purification tank is completed, repeat the above actions. By controlling the rotation angle of the outer gear ring, dosing can be achieved for multiple purification tanks, ultimately completing the dosing operation for the entire annular purification tank group. At the same time, during the rotation of the outer gear ring, the auxiliary rod and stirring rod can be driven to rotate synchronously, thereby agitating the liquid medicine in the tank and preventing the liquid medicine from sticking together.

[0040] It should be noted that the above-mentioned drug dispensing and administration can be controlled by time (e.g., by setting a time relay), and the position of the liquid level sensor should be set according to the volume required for a single drug administration.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
