[0001] The utility model relates to the technical field of water treatment, in particular to a raw water dosing and stirring device. Background Art

[0002] In the process of tap water treatment, various chemical agents need to be added to the water for disinfection, algae removal, flocculation, etc. to achieve the purpose of purifying water. The agents need to be added to the raw water according to the ratio and evenly during the dosing process. In the existing raw water dosing process, water and agents are often added at the top of the equipment, and the raw water is stirred by a separate stirring device.

[0003] For example, a water treatment dosing device disclosed in Chinese Patent No. CN220283647U has a discharge pipe connected to the bottom of the mixing tank. A fixed plate is fixedly connected to the top of the mixing tank. Support rods are fixedly connected to the four sides of the mixing tank. A plurality of round holes are formed in the interior of the fixed plate. A plurality of dosing pipes are fixedly connected to the top of the fixed plate. When in use, the servo motor is started, and the second stirring blade can be used to stir the materials. At the same time, the engagement of the first gear and the second gear can drive the second stirring blade to stir, improving the stirring efficiency.

[0004] In this application, the second stirring blade is driven by a servo motor to stir the materials, and the agents are added through a plurality of round holes to promote the uniform distribution of the agents. However, in the process of water treatment, the form of stirring driven by a servo motor has a high energy consumption.

[0005] Therefore, the present application provides a raw water dosing and stirring device to improve the mixing effect of raw water and agents and solve the problem of high energy consumption of the existing dosing and stirring device. Summary of the Utility Model

[0006] To solve the above problems, the utility model provides a raw water dosing and stirring device.

[0007] The technical solution adopted by the utility model to solve its technical problems is: a raw water dosing and stirring device, including a raw water treatment tank. A partition is arranged on the upper inner side of the raw water treatment tank. A water inlet pipe is connected to the lower part of the raw water treatment tank. The upper end of the water inlet pipe passes through the partition along the axial direction of the raw water treatment tank and is arranged in the upper part of the raw water treatment tank. The upper end of the water inlet pipe is rotatably connected with a distribution head. A spiral paddle is arranged inside the distribution head. A plurality of stirring plates are connected to the outside of the distribution head.

[0008] As an optimization, the middle part of the partition sinks to form a stirring tank. The stirring plates are located in the stirring tank. A plurality of water leakage holes are evenly and densely arranged at the bottom of the stirring tank.

[0009] As an optimization, the partition plate divides the raw water treatment tank into a chemical dosing chamber and a sedimentation chamber, and the sedimentation chamber is located below the chemical dosing chamber.

[0010] As an optimization, an annular distribution box is provided at the inner top of the chemical dosing chamber. A chemical dosing pipe is connected to the top of the distribution box, and distribution holes are uniformly and densely arranged on the bottom surface of the distribution box.

[0011] As an optimization, the lower end of the distribution head is rotatably connected to the upper end of the water inlet pipe, and a plurality of water outlet holes are uniformly formed in the upper part of the distribution head.

[0012] As an optimization, a drain pipe is connected to the upper part of the sedimentation chamber, and a sewage discharge pipe is connected to the lower part of the sedimentation chamber. Valves are connected to both the drain pipe and the sewage discharge pipe.

[0013] The raw water chemical dosing and stirring device of this solution has the following advantages:

[0014] An inlet pipe is arranged inside the raw water treatment tank of this application. The kinetic energy of the inlet water drives the distribution head to rotate, so that the stirring plates outside the distribution head stir and mix the raw water and the chemical agent, ensuring the mixing effect of the raw water and the chemical agent and reducing the energy consumption of the equipment;

[0015] The partition plate divides the raw water treatment tank into a chemical dosing chamber and a sedimentation chamber, so that the water sprayed out by the distribution head is efficiently mixed with the chemical agent inside the chemical dosing chamber, improving the mixing effect and reducing the floor area of the equipment.

[0022] Such as Figures 1-5As shown in the figure, a raw water dosing and stirring device includes a raw water treatment tank 1. Inside the upper part of the raw water treatment tank 1, there is a partition plate 2. The lower part of the raw water treatment tank 1 is connected with a water inlet pipe 3. The upper end of the water inlet pipe 3 passes upward through the partition plate 2 along the axial direction of the raw water treatment tank 1 and is arranged in the upper part of the raw water treatment tank 1. The upper end of the water inlet pipe 3 is rotatably connected with a distribution head 4. Inside the distribution head 4, there is a spiral impeller 5. The outside of the distribution head 4 is connected with a number of stirring plates 6.

[0023] The rotation of the distribution head 4 is driven by the water flow in the water inlet pipe 3. Correspondingly, the water inlet pipe 3 can also be arranged from top to bottom.

[0024] The stirring plates 6 are arranged obliquely. The number of the stirring plates 6 is not less than 2. A plurality of stirring plates 6 are arranged in a circumferential array along the axial direction of the vertical section of the water inlet pipe 3 to ensure the force balance of the distribution head 4.

[0025] As Figure 3 and Figure 4 shown in the figure, in the middle of the partition plate 2, there is a sunken stirring tank 7. The stirring plates 6 are located in the stirring tank 7. The bottom of the stirring tank 7 is evenly and densely provided with a number of water leakage holes 8.

[0032] The raw water enters the distribution head 4 through the water inlet pipe 3, and the water flow drives the distribution head 4 to rotate;

[0033] The water flows through the water outlet holes 13 on the distribution head 4 and is distributed inside the chemical addition chamber 9;

[0034] The chemical agent is added into the chemical addition chamber 9 through the chemical addition pipe 12 and the distribution box 11, so that the chemical agent is evenly distributed inside the chemical addition chamber 9 along the distribution box 11;

[0035] Meanwhile, the distribution head 4 drives the stirring plate 6 to rotate, and stirs the raw water and the chemical agent inside the stirring tank 7 and the chemical addition chamber 9;

[0036] After the chemical agent is evenly mixed with the raw water, it flows into the inside of the sedimentation chamber 10 through the water leakage holes 8 on the partition plate 2 for sedimentation;
