Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a scale inhibitor dosing device for water treatment. Background Technology

[0002] In water treatment, scale inhibitors, as important chemical additives, effectively suppress scaling on the inner walls of equipment and pipelines, ensuring stable system operation. In practical applications, the dosing of scale inhibitors requires precise control through specialized equipment to ensure uniform mixing of the agent and water. Traditional dosing devices typically deliver the agent through fixed pipelines or static mixing methods, with the core objective of simplifying the operation process and improving dosing efficiency.

[0003] Existing dosing systems still have many shortcomings in practical use. For example, fixed dosing pipelines can easily lead to excessively high local concentrations or uneven dispersion of the chemicals, affecting the scale inhibition effect; in static mixing mode, the contact area between the chemicals and water is limited, resulting in low mixing efficiency and potentially causing chemical deposition or agglomeration. Utility Model Content

[0004] This invention provides a scale inhibitor dosing device for water treatment to solve the problems of uneven agent dispersion and low mixing efficiency in existing dosing devices.

[0005] The technical solution adopted by this utility model is as follows: a scale inhibitor dosing device for water treatment, comprising a cylinder, a plurality of support legs fixedly connected to the bottom of the cylinder, a dosing pipe rotatably connected to the top wall of the cylinder, the bottom end of the dosing pipe extending to the bottom of the cylinder and the top end extending to the top of the cylinder, a dosing port fixedly connected to the top end of the dosing pipe, a water inlet fixedly connected to one side of the cylinder, a water outlet fixedly connected to the bottom end of the cylinder and a drain valve provided on the water outlet, a first gear fixedly sleeved on the outside of the dosing pipe, a motor fixedly connected to the top of the cylinder, and the output shaft of the motor passing through the top wall of the cylinder and fixedly connected to a second gear meshing with the first gear.

[0006] As a further improvement of this utility model, the number of supporting legs is not less than three and they are evenly distributed at the bottom of the cylinder.

[0007] As a further improvement of this utility model, the dosing pipe is rotatably connected to the top wall of the cylinder via a bearing.

[0008] As a further improvement of this utility model, multiple hollow tubes are fixedly connected to the outside of the dosing tube.

[0009] As a further improvement of this utility model, the hollow tubes are arranged in a ring array on the outside of the dosing tube, and the end of the hollow tube away from the dosing tube is provided with a dispensing hole.

[0010] The beneficial effects of this invention are as follows: This invention uses a motor-driven gear set to rotate the dosing pipe and hollow tube, causing the scale inhibitor to dynamically diffuse within the cylinder, significantly increasing the contact area and mixing uniformity between the agent and water. The annular array of hollow tubes, combined with the dosing port design, enables multi-directional, dispersed dosing, effectively avoiding problems such as excessively high local concentrations or agent deposition. Furthermore, this invention has a simple and compact structure, high operational stability, and reduces energy consumption and maintenance costs. Attached Figure Description

[0016] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0017] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] This utility model provides the following: Figure 1-4 The scale inhibitor dosing device for water treatment shown includes a cylinder 1. Multiple support legs 2 are fixedly connected to the bottom of the cylinder 1. A dosing pipe 3 is rotatably connected to the top wall of the cylinder 1. The bottom end of the dosing pipe 3 extends to the bottom of the cylinder 1 and the top end of the dosing pipe 3 extends to the top of the cylinder 1. A dosing port 4 is fixedly connected to the top end of the dosing pipe 3. A water inlet 5 is fixedly connected to one side of the cylinder 1. A water outlet 6 is fixedly connected to the bottom end of the cylinder 1 and a drain valve 7 is provided on the water outlet 6. A first gear 8 is fixedly sleeved on the outside of the dosing pipe 3. A motor 9 is fixedly connected to the top of the cylinder 1. The output shaft of the motor 9 passes through the top wall of the cylinder 1 and is fixedly connected to a second gear 10 that meshes with the first gear 8.

[0020] like Figure 1 As shown, in this utility model, the number of support legs 2 is not less than three and they are evenly distributed at the bottom of the cylinder 1, which can provide stable support for the cylinder 1 and ensure that the device will not tip over due to instability of the center of gravity during operation, thus effectively ensuring the safety of equipment operation.

[0021] like Figure 2 and Figure 3 As shown, in this utility model, the dosing tube 3 is rotatably connected to the top wall of the cylinder 1 through the bearing 11, which greatly reduces the friction when the dosing tube 3 rotates, making the motor 9 drive the dosing tube 3 to rotate more smoothly. At the same time, it also reduces the noise and wear during equipment operation and extends the service life of the dosing tube 3 and the entire device.

[0022] like Figure 2-4 As shown, in this utility model, multiple hollow tubes 12 are fixedly connected to the outside of the dosing tube 3. The hollow tubes 12 are arranged in a ring array on the outside of the dosing tube 3, and a drug outlet is provided at the end of the hollow tube 12 away from the dosing tube 3.

[0023] Working Principle: In practical implementation, this invention first injects an appropriate amount of water into the cylinder 1 through the water inlet 5. Then, the scale inhibitor is poured into the dosing pipe 3 through the dosing port 4. The motor 9 is started, and the output shaft of the motor 9 drives the second gear 10 to rotate. The second gear 10 meshes with the first gear 8, thereby driving the dosing pipe 3 to rotate. Simultaneously, the hollow pipe 12 rotates, and the scale inhibitor is dispersed and ejected through the outlet holes on the hollow pipe 12, forming dynamic diffusion within the cylinder and fully mixing with the water inside. The uniformly mixed solution is discharged from the water outlet 6. The drain valve 7 controls the discharge speed and flow rate of the solution to meet the needs of different water treatment scenarios. Throughout the dosing process, the mixing efficiency of the agent and water is significantly improved, avoiding problems such as excessively high local concentrations of the agent or sedimentation and clumping, achieving efficient and precise scale inhibitor dosing operation.

[0024] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
