Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a water treatment agent slow-release device. Background Technology

[0002] Wastewater treatment refers to the process of removing pollutants from water using physical, chemical, or biological methods. These pollutants include suspended solids, dissolved solids, grease, heavy metals, and pathogens, enabling the wastewater to meet prescribed discharge standards or reuse requirements. In wastewater treatment, chemical methods often require the addition of specific agents to remove pollutants. Commonly used chemical agents include coagulants, flocculants, precipitants, oxidants, and reducing agents.

[0003] Chinese Patent Application No. 202223419873.5 and Publication No. CN219174230U discloses a wastewater treatment agent dosing device, including a treatment tank, a hydraulic rod arranged along the axis of the treatment tank, a dosing box arranged on the hydraulic rod, the dosing box including a liquid storage tank and a solid tank; a stirring mechanism, the stirring mechanism including a first motor arranged at the center of the hydraulic rod, the output shaft of the first motor being fixedly connected to a placement block, a cylinder arranged inside the placement block, the cylinder being arranged perpendicular to the first motor, the output shaft of the cylinder being fixedly connected to a discharge rod, the end of the discharge rod being provided with a discharge block; a discharge pipe, the discharge pipe including a first discharge pipe and a second discharge pipe, the first discharge pipe connecting the liquid storage tank and the discharge block; a cutting mechanism, the cutting mechanism being located below the solid tank and communicating with the solid tank, the second discharge pipe connecting the cutting mechanism and the discharge block.

[0004] In summary, most existing wastewater treatment chemical dosing devices are single-use and lack a slow-release function, leading to rapid chemical consumption, waste, and increased wastewater treatment costs. Furthermore, chemicals added to wastewater in a single application may cause environmental pollution due to excessive concentrations. Therefore, this application proposes a slow-release device for water treatment chemicals. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. Example

[0019] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a water treatment agent slow-release device, including a treatment tank 1, a feeding pipe 3 passing through the top cover of the treatment tank 1, specifically, the feeding pipe 3 is fixedly connected to the top cover of the treatment tank 1, an agent tank 2 is located above the feeding pipe 3, and a discharge pipe 4 is located on the bottom surface of the agent tank 2, specifically, the discharge pipe 4 is connected to the agent tank 2 and is fixedly connected, a connecting pipe 5 is connected to the top of the feeding pipe 3, specifically, the connecting pipe 5 is connected to the feeding pipe 3 and is fixedly connected, the connecting pipe 5 extends into the interior of the discharge pipe 4 and is connected to the discharge pipe 4. The pipe 4 is slidably connected. The inner wall of the discharge pipe 4 is provided with several elastic sealing plates 6 above the connecting pipe 5. One end of the elastic sealing plate 6 located on the central axis of the discharge pipe 4 is in a free state. The end of the elastic sealing plate 6 is fixedly connected to the inner wall of the discharge pipe 4. The several elastic sealing plates 6 cooperate with each other to seal the discharge pipe 4. The bottom surface of the medicine tank 2 and the top surface of the treatment tank 1 are symmetrically provided with electric telescopic rods 7. Specifically, the two ends of the electric telescopic rod 7 are fixedly connected to the bottom surface of the medicine tank 2 and the top surface of the treatment tank 1, respectively, and the electric telescopic rod 7 drives the medicine tank 2.

[0020] In this embodiment, the medicine is placed in the medicine tank 2 in advance. At this time, several elastic sealing plates 6 cooperate with each other to seal the discharge pipe 4. When the medicine needs to be added, the electric telescopic rod 7 is activated to drive the medicine tank 2 to move downward, which in turn moves the discharge pipe 4 downward. This causes the connecting pipe 5 to push open the elastic sealing plates 6 and connect with the medicine tank 2. The medicine enters the feeding pipe 3 through the connecting pipe 5 and is then added to the treatment tank 1. After a certain amount of medicine is added, the electric telescopic rod 7 is activated in reverse to drive the medicine tank 2 to move upward. The elastic sealing plates 6 reseal the discharge pipe 4, thereby realizing intermittent medicine addition and thus achieving slow release of the medicine.

[0021] Furthermore, the top cover of the treatment tank 1 is provided with an inlet pipe, and the side wall of the treatment tank 1 is provided with an outlet pipe.

Specifically, the spiral blade 13 slides along the inner wall of the feeding pipe 3. A rotation drive assembly is connected to the bottom of the rotating shaft 11. Specifically, the rotation drive assembly can drive the rotating shaft 11 to rotate.

[0024] In this embodiment, the rotating drive assembly drives the rotating shaft 11 to rotate, causing the spiral blade 13 to rotate circumferentially along the inner wall of the feeding pipe 3, thereby realizing the spiral feeding of the agent and further slowing down the release of the agent.

[0025] Furthermore, the rotation drive assembly includes a gear ring 10, which is sleeved on the bottom outer side of the rotating shaft 11. A connecting rod 12 is symmetrically arranged between the side wall of the rotating shaft 11 and the inner wall of the gear ring 10.

Specifically, the output shaft of the motor 8 is slidably connected to the top cover of the processing tank 1 and fixedly connected to the gear 9.

[0026] In this embodiment, by starting the motor 8, the gear 9 is driven to rotate, which in turn drives the gear ring 10 to rotate, thereby realizing the rotation of the shaft 11 and the spiral blade 13.

[0027] Furthermore, the bottom surface of the toothed ring 10 is provided with an annular plate 14, which is connected to the inner wall of the treatment tank 1. Specifically, the annular plate 14 is fixedly connected to the inner wall of the treatment tank 1, and the bottom surface of the toothed ring 10 is slidably connected to the top surface of the annular plate 14.

[0028] In this embodiment, an annular plate 14 is provided to limit the toothed ring 10.

[0029] Furthermore, an annular limiting block 15 is provided on the top surface of the annular plate 14 inside the toothed ring 10. Specifically, the annular limiting block 15 is fixedly connected to the annular plate 14, and the annular limiting block 15 is located below the connecting rod 12. The inner wall of the toothed ring 10 is slidably connected to the annular limiting block 15.

[0030] In this embodiment, an annular limiting block 15 is provided to further limit the toothed ring 10 and prevent the toothed ring 10 from deviating.
