Description

Technical Field

[0001] This utility model relates to the field of water treatment dosing technology, specifically a dosing device for water treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. There are many methods for treating wastewater, which can generally be categorized into physical methods, chemical methods, and biological methods. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. When using chemical methods to treat wastewater, a dosing device is needed to add reaction solutions to the wastewater.

[0003] Chinese Patent CN217051735U discloses an underwater dosing device for water pollution treatment. The device includes a box with an open top, containing a stirring chamber and an operating chamber. The stirring chamber is located above the operating chamber. A cover plate is fixedly installed on the top of the box, and two guide pipes are fixedly installed on the cover plate, both communicating with the stirring chamber. A cylinder is located above the box, containing two storage chambers. Two discharge ports are located at the bottom of the cylinder, each communicating with a corresponding storage chamber. A support frame is fixedly installed on the top of the box. This underwater dosing device for water pollution treatment provides the advantages of accelerating the diffusion rate of the chemical powder, ensuring uniform mixing between clean water and the chemical powder, and improving the mixing degree between the chemical solution and wastewater.

[0004] However, in the above-mentioned technical solutions, during the mixing process of the liquid medicine, various precipitates or impurities may be mixed in the liquid medicine. When the liquid medicine is sprayed out from the branch pipe, these precipitates or impurities are easy to adhere to the nozzle. Over time, this can easily cause the nozzle to become clogged and reduce the dosing efficiency of the entire device. Therefore, this utility model proposes a dosing device for water treatment to solve the above problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a dosing device for water treatment, the dosing device for water treatment includes: a support frame 1, a limiting ring 2 provided on the surface of the support frame 1, a mixing cylinder 3 placed on the surface of the support frame 1, a support rod 4 provided inside the mixing cylinder 3, a stirring plate 5 provided on the side of the support rod 4, a drive motor 6 provided on the upper surface of the mixing cylinder 3, a discharge pipe 7 provided at the bottom of the support frame 1, and a filter frame 8 provided inside the discharge pipe 7;

[0024] A support plate 9 is provided with a water pump 10 on its surface. A hose 11 is provided at the output end of the water pump 10. A nozzle 12 is provided at one end of the hose 11. A water delivery pipe 13 is provided at the input end of the water pump 10.

[0025] First, pour various powdered medicines into the mixing drum 3. Then, start the drive motor 6 to rotate the stirring plate 5, which will stir and mix the powdered medicines in the water evenly. Then, open the valve body and use the water pump 10 in conjunction with the nozzle 12 to put the medicine into the water for treatment. The feed pipe 7 is equipped with a filter frame 8 to filter out larger particles in the medicine, preventing them from entering the nozzle 12 and causing blockage. It is also relatively inconvenient to remove blockages from the nozzle 12.

[0026] Example 2: Based on Example 1, a support rod 4 is provided to facilitate uniform mixing of the powder and water. A limiting ring 2 is fixedly connected to the surface of the support frame 1. A sealing gasket 14 is provided at the bottom of the mixing cylinder 3. An installation plate is provided on the side of the mixing cylinder 3. A positioning bolt 15 is screwed into the installation plate. A threaded hole is opened on the surface of the limiting ring 2. The positioning bolt 15 can be screwed into the threaded hole. A through hole is opened on the upper surface of the mixing cylinder 3. A sealing bearing 16 is provided in the through hole. The support rod 4 is fixedly connected to the inner ring surface of the sealing bearing 16. The transmission end of the drive motor 6 is fixedly connected to the end face of the support rod 4.

[0027] During use, the drive motor 6, in conjunction with the sealed bearing 16, drives the support rod 4 to rotate, thereby causing the stirring plate 5 to stir. This facilitates the mixing of the powder in the water, eliminating the need for manual stirring. Subsequently, the powder can be easily added using the water pump 10 and the nozzle 12. When it is necessary to remove the mixing cylinder 3 for internal cleaning, the positioning bolt 15 can be rotated to remove it from the limiting ring 2, allowing the mixing cylinder 3 to be directly removed from the limiting ring 2 for cleaning. The sealing gasket 14 increases the sealing between the mixing cylinder 3 and the surface of the support frame 1, preventing leakage.

[0028] Example 3: Based on Example 2, a filter frame 8 is provided to avoid clogging of the nozzle 12. The support plate 9 is fixedly connected to the bottom of the support frame 1. The water pump 10 is fixedly connected to the surface of the support plate 9 by bolts. One end of the water supply pipe 13 is connected to the input end of the water pump 10, and the other end of the water supply pipe 13 is connected to the inside of the discharge pipe 7. A valve body is provided inside the discharge pipe 7. The inner ring surface of the discharge pipe 7 is threaded, and a sealing bolt 17 is screwed onto the thread. A threaded groove 18 is provided on the surface of the sealing bolt 17. A positioning rod 19 is screwed into the threaded groove 18. The filter frame 8 is fixedly connected to the end face of the positioning rod 19.

[0029] During use, the liquid medicine in the mixing drum 3 can be discharged by opening the valve body set in the discharge pipe 7. After being contained, the liquid medicine can be filtered by the filter frame 8 set in the discharge pipe 7. When it is necessary to clean the inside of the filter frame 8, the valve body in the discharge pipe 7 can be closed. Then, while the liquid medicine is being stirred in the mixing drum 3, the sealing bolt 17 can be screwed out from the discharge pipe 7. Then the filter frame 8 can be cleaned. Alternatively, the positioning rod 19 can be screwed out from the threaded groove 18 to separate the filter frame 8 from the sealing bolt 17 for storage.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
