Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment agent dosing device. Background Technology

[0002] Wastewater treatment is a process of purifying wastewater to meet the water quality standards for discharge into specific water bodies or for reuse. This process typically involves adding chemicals to separate pollutants from the wastewater. However, these chemicals must first be mixed with water for dilution, and there are many types and forms of chemicals, including powders and liquids. Powdered chemicals, in particular, tend to adhere to and remain on the inner walls of the mixing tank after being added. This not only prevents the powdered chemicals from dispersing evenly in the water during subsequent mixing and dilution, thus affecting effective mixing and reaction, but may also reduce the efficiency and quality of wastewater treatment due to chemical residue. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater treatment agent dosing device, aiming to solve the problem that in the prior art, powdered agents, after being added to the mixing tank, often tend to be adsorbed and remain on the inner wall of the mixing tank. This not only prevents the powdered agent from being evenly dispersed in the water during subsequent stirring and dilution processes, thus affecting the effective mixing and reaction of the agent, but may also reduce the efficiency and quality of wastewater treatment due to agent residue.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment agent dosing device, comprising a mounting frame, a dosing and mixing tank, and a control mechanism. The dosing and mixing tank is equipped with a stirring mechanism, which consists of a servo motor and a stirring rod. The top surface of the dosing and mixing tank is connected to a dosing port, and a scraper is installed at the end of the stirring rod near the inner wall of the dosing and mixing tank.

[0005] In a preferred embodiment of the wastewater treatment agent dosing device of this utility model, the scraper is attached to the inner wall of the dosing and mixing tank via a stirring rod.

[0006] In a preferred embodiment of the wastewater treatment agent dosing device of this utility model, the scraper is rotatably connected to the dosing and mixing tank via a stirring mechanism.

[0007] As a preferred embodiment of the wastewater treatment agent dosing device of this utility model, the mounting frame is internally connected to the bottom of the mixing tank with a bidirectional threaded rod. One end of the bidirectional threaded rod is equipped with a handle, and the other end of the bidirectional threaded rod is equipped with a bearing seat, which is fixedly connected to the side wall of the mounting frame.

[0008] In a preferred embodiment of the wastewater treatment agent dosing device of this utility model, the opposing threads on the surface of the bidirectional threaded rod are symmetrical, and a threaded sleeve is threadedly connected to the surface of the bidirectional threaded rod. The threaded sleeve forms a threaded movement between the bidirectional threaded rod and the mounting frame.

[0009] As a preferred embodiment of the wastewater treatment agent dosing device of this utility model, the threaded sleeve is adapted to the size of the internal groove of the mounting frame, and a clamping plate is integrally connected to the top of the threaded sleeve.

[0010] As a preferred embodiment of the wastewater treatment agent dosing device of this utility model, a fixing pin is provided through the outer wall of the handle, and the fixing pin forms a detachable threaded connection between the handle and the mounting bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention effectively removes residual powder from the inner wall of the mixing tank through a rotating connection design between the scraper and the stirring mechanism. This design ensures that the powder is fully mixed with water, avoiding uneven mixing caused by powder adhering to the inner wall of the mixing tank, thus guaranteeing the quality of the mixture and further improving the efficiency and quality of wastewater treatment. Furthermore, the mixing tank is securely fixed through a tight fit between the bidirectional threaded rod and the clamping plate, effectively preventing instability caused by centrifugal force generated during the mixing process. This improvement further enhances the stability of the mixing tank during use, ensuring the smooth progress of the mixing process. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: a wastewater treatment agent dosing device, including a mounting frame 1, a dosing and mixing tank 2 and a control mechanism 3. The dosing and mixing tank 2 is equipped with a stirring mechanism 4, which is composed of a servo motor 41 and a stirring rod 42. The top surface of the dosing and mixing tank 2 is connected to a dosing port 5, and a scraper 6 is installed at the end of the stirring rod 42 near the inner wall of the dosing and mixing tank 2.

[0022] In a preferred embodiment: the scraper 6 is attached to the inner wall of the mixing tank 2 via the stirring rod 42.

[0023] In a preferred embodiment: the scraper 6 is rotatably connected to the mixing tank 2 via the stirring mechanism 4.

[0024] In this embodiment, the agent dispensing device consists of a mounting frame 1, a dispensing and mixing tank 2, and a control mechanism 3. It is a mature existing technology and is model JY-500 single-tank fully automatic dosing device. It has the function of quantitatively dispensing agents. When using the agent dispensing device, it needs to be connected to the sewage treatment equipment to facilitate the delivery of the diluted and mixed agents into the sewage treatment equipment. Therefore, the specific usage and working principle will not be described in detail in this article.

[0025] When the powdered medicine is fed into the mixing tank 2 through the dosing port 5 and mixed and diluted with water to form a medicine, the powder tends to adhere to the inner wall of the mixing tank 2. To solve this problem, when the stirring mechanism 4 is working, the servo motor 41 is activated through the control mechanism 3, driving the stirring rod 42 to rotate. At the same time, the stirring rod 42 also drives the scraper 6 to rotate, making the scraper 6 fit tightly against the inner wall of the mixing tank 2. In the rotating state, the scraper 6 can scrape off the powder adsorbed on the inner wall of the mixing tank 2 and let it flow into the water. This design ensures that the powder can be fully mixed with water, avoiding the problem of uneven mixing caused by adsorption, thereby ensuring the quality of the medicine formed by the powder and water, and further improving the efficiency and quality of wastewater treatment.

[0026] Example 2

[0027] Please see Figure 1-4 The mounting frame 1 is connected to the bottom of the mixing tank 2 by a double-threaded rod 7. One end of the double-threaded rod 7 is equipped with a handle 11, and the other end of the double-threaded rod 7 is equipped with a bearing seat 8. The bearing seat 8 is fixedly connected to the side wall of the mounting frame 1.

[0028] In a preferred embodiment: the opposite threads on the surface of the bidirectional threaded rod 7 are symmetrical, and the surface of the bidirectional threaded rod 7 is threadedly connected to a threaded sleeve 9. The threaded sleeve 9 forms a threaded movement between the bidirectional threaded rod 7 and the mounting bracket 1.

[0029] In a preferred embodiment: the threaded sleeve 9 is adapted to the size of the internal groove of the mounting bracket 1, and the top of the threaded sleeve 9 is integrally connected to the clamping plate 10.

[0030] In a preferred embodiment: a fixing pin 12 is provided through the outer wall of the handle 11, and the fixing pin 12 passes through the handle 11 and the mounting bracket 1 to form a detachable threaded connection.

[0031] In this embodiment, as described in Embodiment 1, during the process of mixing the powder and water in the mixing tank 2 to form the medicine, the rotation of the stirring mechanism 4 generates centrifugal force, which may cause the mixing tank 2 to be unstable. To solve this problem, the operator needs to manually rotate the fixing pin 12, thereby driving the bidirectional threaded rod 7 to rotate. The bidirectional threaded rod 7 then rotates along the inner ring of the bearing assembled inside the bearing seat 8. At this time, the opposite threads on its surface cause the threaded sleeves 9 to move closer together. As the threaded sleeves 9 move closer, they respectively drive the clamping plates 10 to move towards the outer wall of the mixing tank 2, forming an effective clamping and fixing of the mixing tank 2. This improvement significantly enhances the stability of the mixing tank 2 during use, ensuring the smooth progress of the medicine mixing process. The mixed medicine is then sent to the sewage treatment equipment for sewage treatment.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
