Description

Technical Field

[0001] This utility model relates to the field of wastewater purification, and in particular to a vertical circulating mixer for wastewater treatment. Background Technology

[0002] Vertical circulating mixers are suitable for use in wastewater treatment plants and industrial processes, for mixing liquids containing suspended solids; mixing and homogenizing sewage, wastewater, and sludge water; thickening processes; sludge dewatering processes; heat transfer; cleaning sewage tanks; preventing particle coagulation and sedimentation on tank walls and bottoms; removing suspended solids; and creating water flow. For example, Nanjing Aotelan Environmental Equipment Co., Ltd. sells vertical circulating mixers with floats, which include a floating body that floats on the sewage, a mixing mechanism submerged in the sewage, and a connecting mechanism connecting the floating body and the sewage mixing mechanism. The floating body has a U-shaped concave side, and the floating body is circular, with the bottom of the U-shaped concave part located at the center of the floating body. The floating body is a floating bucket. The connecting mechanism includes two parallel upper rods, two parallel lower rods, and a vertical rod. The lower rods are welded to the bottom of the upper rods and are located in the U-shaped recess. The two ends of the upper rods are connected by rods, which are fixed to the floating bucket by a first bolt. Mounting rings are provided at both ends of the rods, and these rings are fixed to the shore by a rope. The bottom of the vertical rod is connected to the stirring mechanism, and the top of the vertical rod is provided with a mounting plate, which is connected to the lower rods by a second bolt. However, in use, the stirring mechanism cannot be directly installed onto the floating bucket using the mounting plate, resulting in poor installation stability and inability to be secured by a rope. Furthermore, installation requires the installation of the rods, the upper and lower rods, and the mounting plate and lower rod, making the structure complex, slow to assemble and disassemble, and inefficient. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a vertical circulating mixer for wastewater treatment, which features robust installation, good stability, simple structure, fast assembly and disassembly, and high efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vertical circulating mixer for sewage treatment, comprising a floating body floating in sewage, a mixing mechanism submerged in sewage, and a connecting mechanism connecting the floating body and the sewage mixing mechanism. The connecting mechanism includes a vertical rod and a mounting plate connected to the top of the vertical rod. The side of the floating body is concave to form a U-shaped recess, and a U-shaped slide rail is provided inside the recess. The lower surface of the mounting plate is provided with a protrusion that can slide along the U-shaped slide rail to the bottom of the U-shaped recess. The U-shaped slide rail is provided with a mounting hole at the bottom of the U-shaped recess. The mounting plate is provided with a mounting rod that passes through the protrusion and connects to the mounting hole. The mounting plate has a supporting outer edge that fits tightly against the upper surface of the floating body. During installation, the vertical rod moves along the U-shaped recess, which in turn moves the protrusion along the U-shaped slide rail to the bottom of the U-shaped recess. Then, it is fixed through the mounting holes and mounting rod, thus achieving quick assembly and disassembly. The structure is simple. Moreover, the mounting plate is directly supported on the upper surface of the float by the outer support and is also supported by the protrusion on the U-shaped slide rail, achieving double support from the float to the mounting plate, ensuring the firmness and stability of the mounting plate installation.

[0005] Furthermore, mounting rings are distributed around the outer surface of the support. This allows the pull rope to be fixed via the mounting plate, eliminating the need for a support bar and further simplifying the structure.

[0006] Furthermore, there are four mounting rings.

[0007] Furthermore, the floating body is circular, and the bottom of the U-shaped recess is located at the center of the floating body.

[0008] Furthermore, the floating body is a floating barrel.

[0009] In summary, the beneficial effects of this utility model are as follows: the outer edge of the mounting plate of this product is directly supported on the floating body, the protrusion is supported on the U-shaped slide rail, and then it is fixed by the mounting rod. The stirring mechanism can be installed on the floating tank by the mounting plate. The installation is firm and stable, the structure is simple, the disassembly and assembly are convenient, fast and efficient. Attached Figure Description

[0017] like Figure 1-5 As shown, a vertical circulating mixer for wastewater treatment includes a floating body 1, a mixing mechanism 2, and a connecting mechanism 3. The floating body 1 floats on the surface of the wastewater and is circular, serving as a floating bucket. The mixing mechanism 2 is submerged in the wastewater. The connecting mechanism 3 connects the floating body 1 and the wastewater mixing mechanism 2. The side of the floating body 1 is concave, forming a U-shaped recess 4, with the bottom of the U-shaped recess 4 located at the center of the floating body 1. The mixing mechanism 2 includes a mixing motor, a mixing rod, and mixing blades. The bottom of the mixing motor is connected to the mixing rod, and mixing blades are provided around the periphery of the mixing rod. The connecting mechanism 3 includes a vertical rod 31 and a mounting plate 32. The mounting plate 32 is connected to the top of the vertical rod 31, and the bottom end of the vertical rod 31 is connected to the mixing motor via a flange. These structures are the same as those of existing vertical circulating mixers and will not be described in detail here.

[0018] The improvement of this product lies in the fact that a U-shaped slide rail 41 is provided on the inner side of the recess 4. The mounting plate 32 is circular, and a cylindrical protrusion 33 is provided on the lower surface of the mounting plate 32. The protrusion 33 can slide along the U-shaped slide rail 41 to the bottom of the U-shaped recess 4. The U-shaped slide rail 41 has three evenly distributed mounting holes 42 at the bottom of the U-shaped recess 4. The mounting plate 32 is provided with a mounting rod 43.

[0019] A plurality of mounting rings 5 ​​are evenly distributed around the outer surface of the support outer edge 321. Preferably, there are four mounting rings 5, which are vertically welded to the upper surface of the support outer edge 321.

[0020] In use, move the vertical rod 31 along the U-shaped recess 4 towards the center of the float 1. At this time, the protrusion 33 moves along the U-shaped slide rail 41, and the outer support 321 moves along the top surface of the float 1 to the center of the float 1. The protrusion 33 then reaches the bottom of the U-shaped recess 4. Next, pass the bottom end of the mounting rod 43 through the mounting plate 32 and the protrusion 33, and insert it into the mounting hole 42. Rotate the mounting rod 43 clockwise until it is threaded into the mounting hole 42. Then, tie one end of the rope to the mounting ring 5 and place the product into the sewage tank. Tie the other end of the rope to the side of the sewage tank for fixation.
