Description

Technical Field

[0001] This utility model relates to an enhanced mixing and stirring device. Background Technology

[0002] High-efficiency sedimentation tanks are important devices for solid-liquid separation. Through physical sedimentation, they effectively remove suspended solids, particulate matter, and other impurities from wastewater, thereby improving water quality and protecting the environment. The working principle of a high-efficiency sedimentation tank is mainly based on two processes: gravity settling and particle collision and coagulation. As wastewater flows through the sedimentation tank, suspended solids gradually settle under gravity, forming a sludge layer, while clear water flows out from the top, achieving solid-liquid separation.

[0003] The particle collision and coagulation process mainly takes place in the tank where flocculants are added. Coagulation and agitation are used to induce collisions and coagulation between suspended particles, forming larger flocs to accelerate the settling process. However, existing coagulation and agitation devices in tanks where flocculants are added mainly consist of a guide tube and a stirring blade. The inner wall of the guide tube is smooth, limiting the collision effect between suspended particles during the upward pumping of liquid, and the coagulation and agitation effect needs further improvement. For example, the guide tube and flocculation agitator disclosed in a high-efficiency sedimentation tank (patent publication number CN208327611U) are examples. Therefore, a more advanced mixing and agitation device is needed. Utility Model Content

Detailed Implementation

[0016] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0017] refer to Figure 1 and Figure 2 An enhanced mixing device includes a flow guide cylinder 10 mounted in the middle of a tank 1 via a fixed frame. A vertical rotating shaft 20, driven by a drive mechanism, is installed inside the flow guide cylinder. A paddle 21, designed to direct liquid upwards within the flow guide cylinder, is mounted at the lower end of the shaft. The paddle has reinforcing ribs to improve its strength. Vertical flow guide baffles 11 are fixed at intervals along the circumferential direction on the inner wall of the flow guide cylinder. Several radially protruding baffles 12 are positioned between the upper parts of adjacent vertical flow guide baffles. The vertical flow guide baffles divide the water flow entering the flow guide cylinder, and the baffles further alter the water flow direction, thereby improving the mixing effect.

[0018] In this embodiment, in order to fix the guide tube in the pool, the fixing frame includes a horizontal fixing rod 31. Several horizontal fixing rods are welded at intervals along the circumferential direction on the upper and lower parts of the outer wall of the guide tube. The outer ends of the horizontal fixing rods are fixedly connected to the side wall of the pool. Several vertical rods 32 are welded at intervals along the circumferential direction on the lower end of the guide tube. The lower ends of the vertical rods are fixed to the bottom plate of the pool, thereby fixing the guide tube.

[0019] In this embodiment, in order to better fix the transverse fixing rod to the side wall of the pool, the other end of the transverse fixing rod is welded and fixed to the expansion screw 33 pre-embedded in the side wall of the pool.

[0020] In this embodiment, in order to drive the vertical rotating shaft to rotate, the driving mechanism includes a mounting frame 41 fixed to the upper end of the pool body. The mounting frame is equipped with a drive motor 42, and the output end of the drive motor is connected to the upper end of the vertical rotating shaft via a coupling.

[0021] In this embodiment, in order to ensure the stability of the vertical rotating shaft during rotation, a pair of bushings 43 are fitted on the upper side of the guide tube on the vertical rotating shaft, and a connecting rod 44 fixed to the side wall of the pool is fixed on the outer wall of the bushing.

[0022] In this embodiment, in order to better divide the space within the flow guide tube, the vertical flow guide baffle protrudes radially by 4-6 cm. Specifically, the vertical flow guide baffle may protrude radially by 5 cm.

[0023] In this embodiment, at least two layers of baffles are arranged from bottom to top between the upper parts of two adjacent vertical guide baffles, with the baffles arranged at intervals along the arc direction of the inner wall of the guide tube. The baffles between the upper and lower adjacent layers are staggered, thereby better changing the water flow direction, forming turbulence, and promoting better collision and coagulation between suspended particles.

[0024] In this embodiment, the baffle is triangular and has a rounded corner at the end facing the vertical rotating shaft, and the baffle protrudes radially by 3-5 cm. Specifically, the baffle protrudes by 4 cm, and the bottom edge of the baffle connected to the guide tube is 4-5 cm wide.

[0025] In this embodiment, a flared opening can be provided at the lower end of the guide tube to allow water to enter the guide tube more effectively.

[0026] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0027] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0028] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.
