Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a novel mixing device for wastewater treatment. Background Technology

[0002] Wastewater treatment utilizes physical, chemical, and biological methods to purify wastewater, reduce pollution, and achieve wastewater recycling and reuse, thus fully utilizing water resources. Commonly used agents in wastewater treatment include flocculants, coagulants, and conditioners. These agents need to be mixed with the wastewater during treatment. However, since wastewater and agents are usually added to the mixing tank separately through their respective pipelines, the uniformity of agent distribution within the mixing tank is poor, making it difficult for the agents to mix thoroughly with the wastewater. This results in a long mixing time, affecting wastewater treatment efficiency. Based on this, this invention designs a novel mixing device for wastewater treatment to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a new type of mixing device for wastewater treatment to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel mixing device for wastewater treatment includes a base, a mixing tank, a wastewater pipe, and a liquid guide cover. The mixing tank is fixedly installed on the upper end of the base. A premixing pipe is fixedly connected to the middle of the upper end of the mixing tank. The wastewater pipe is fixedly connected to the side of the premixing pipe. A reagent pipe is fixedly connected to the upper end of the liquid guide cover. A cap is provided at the upper end of the premixing pipe. Four distributing pipes are fixedly connected at equal intervals in an annular pattern between the bottom of the liquid guide cover and the top of the cap. A motor is fixedly installed at the bottom of the mixing tank, inside the base. A drive shaft extending into the mixing tank is fixedly connected to the drive end of the motor. Several stirring rods are fixedly connected at intervals to the side of the drive shaft. A flow guide seat is fixedly connected to the end of the drive shaft, directly below the premixing pipe. Four sets of drainage holes are opened at equal intervals in an annular pattern on the surface of the flow guide seat. Liquid-carrying protrusions are fixedly connected to the surface of the flow guide seat between adjacent drainage hole sets.

[0006] As a preferred embodiment of this utility model, the upper end of the wastewater pipe is fixedly connected to a first connector, and the upper end of the reagent pipe is fixedly connected to a second connector.

[0007] As a preferred embodiment of the present invention, the drainage hole group includes a plurality of drainage holes, which are distributed at equal intervals.

[0008] As a preferred embodiment of this utility model, the guide seat is tapered, and the axis of the guide seat coincides with the axis of the transmission shaft.

[0009] As a preferred embodiment of this utility model, a stirring blade is fixedly connected between the longitudinally adjacent stirring rods, and a liquid inlet is provided on the side of the stirring blade.

[0010] As a preferred embodiment of this utility model, the bottom side of the mixing tank is fixedly connected to an outlet pipe, and an on / off valve is provided on the outlet pipe.

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

[0012] This invention allows wastewater to enter a premixing pipe through a wastewater pipe, and chemicals to enter a liquid guide hood through a chemical guide pipe. The chemicals in the liquid guide hood can then be dispersed into the premixing pipe through various distribution pipes, ensuring effective pre-mixing of the wastewater and chemicals during feeding. A motor drives the transmission shaft to rotate, and the guide seat effectively diffuses the liquid discharged from the premixing pipe. A portion of the liquid on the guide seat is directly discharged into the mixing tank through various drain holes. The liquid-laden strips further disperse the remaining liquid on the guide seat into the mixing tank, improving the uniformity of the chemical distribution within the mixing tank. This facilitates rapid and thorough mixing of the chemicals and wastewater, reducing the required mixing time and improving wastewater treatment efficiency. Attached Figure Description

[0019] like Figures 1 to 4 As shown, this utility model provides a novel mixing device for wastewater treatment, including a base 1, a mixing tank 2, a wastewater pipe 4, and a liquid guide shroud 5. The mixing tank 2 is fixedly installed on the upper end of the base 1. A premixing pipe 3 is fixedly connected to the middle of the upper end of the mixing tank 2. The wastewater pipe 4 is fixedly connected to the side of the premixing pipe 3, and wastewater enters the premixing pipe 3 through the wastewater pipe 4. A reagent pipe 6 is fixedly connected to the upper end of the liquid guide shroud 5, and the reagent enters the liquid guide shroud 5 through the reagent pipe 6. A cap 301 is provided at the upper end of the premixing pipe 3. Four distributing pipes 501 are fixedly connected in an annular, equidistant manner between the bottom of the liquid guide shroud 5 and the top of the cap 301. The reagent in the liquid guide shroud 5 can be... The wastewater enters the premixing tube 3 in a dispersed manner through each distributing pipe 501, so that the wastewater and the reagent premixing tube 3 are effectively premixed during feeding. The bottom of the mixing tank 2 is fixedly installed on the inner side of the base 1. The drive end of the motor 7 is fixedly connected to a drive shaft 701 extending into the mixing tank 2. Several stirring rods 702 are fixedly connected at intervals on the side of the drive shaft 701. The end of the drive shaft 701 is fixedly connected to a guide seat 8 directly below the premixing tube 3. The surface of the guide seat 8 is provided with four sets of drainage holes 801 at equal intervals in an annular shape. Liquid-carrying protrusions 802 are fixedly connected between adjacent drainage hole sets 801 on the surface of the guide seat 8.

[0020] Among them, such as Figure 1 and Figure 2 As shown, the upper end of the wastewater pipe 4 is fixedly connected to a first connector 401, and the upper end of the chemical pipe 6 is fixedly connected to a second connector 601, so that the wastewater pipe 4 and the chemical pipe 6 can be connected to the corresponding pipeline.

[0021] Among them, such as Figure 4 As shown, the drain hole group 801 includes several drain holes, which are distributed at equal intervals, so that some liquid on the guide seat 8 can be directly discharged into the mixing tank 2 through each drain hole.

[0022] Among them, such as Figure 3 As shown, the guide seat 8 is conical in shape, and the axis of the guide seat 8 coincides with the axis of the drive shaft 701, so that the guide seat 8 can have a good diffusion effect on the liquid material discharged from the premixing pipe 3.

[0023] Among them, such as Figure 3As shown, a stirring plate 703 is fixedly connected between longitudinally adjacent stirring rods 702. A liquid inlet 704 is provided on the side of the stirring plate 703, so that the stirring rods 702 and the stirring plate 703 can cooperate to achieve a good stirring effect on the liquid in the mixing tank 2.

[0024] Among them, such as Figure 3 As shown, the bottom side of the mixing tank 2 is fixedly connected to the liquid outlet pipe 201, and the liquid outlet pipe 201 is equipped with a switch valve 202. After the wastewater and the reagent in the mixing tank 2 have been mixed and treated, the switch valve 202 can be opened to discharge the liquid in the mixing tank 2 through the liquid outlet pipe 201.

[0025] The working principle of this utility model:

[0026] During use, wastewater enters the premixing pipe 3 through the wastewater pipe 4, and the reagent enters the liquid guide hood 5 through the reagent pipe 6. The reagent in the liquid guide hood 5 can be dispersed into the premixing pipe 3 through each liquid distribution pipe 501, so that the wastewater and the reagent in the premixing pipe 3 are effectively premixed during feeding. The drive shaft 701 is driven by the motor 7 to rotate. The guide seat 8 can play a good diffusion effect on the liquid discharged from the premixing pipe 3. A part of the liquid on the guide seat 8 is directly discharged into the mixing tank 2 through each drain hole. The other part of the liquid on the guide seat 8 is dispersed into the mixing tank 2 by the driving action of the liquid-carrying protrusion 802, thereby improving the uniformity of the reagent distribution in the mixing tank 2, so as to facilitate the rapid and thorough mixing of the reagent and the wastewater. After the mixing treatment of wastewater and reagent in the mixing tank 2 is completed, the switch valve 202 is opened to discharge the liquid in the mixing tank 2 through the liquid outlet pipe 201.
