Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated flocculation and air flotation device for the characteristics of seaweed blanching wastewater. Background Technology

[0002] Seaweed blanching wastewater is a key byproduct in the processing of seaweed (such as kelp and wakame). It mainly comes from the cooling process after fresh kelp is blanched in hot water at 80-90℃. This type of wastewater is characterized by high organic matter concentration, high salinity, and high suspended solids. If discharged directly, it will cause eutrophication of marine waters (leading to ecological problems such as red tides). Therefore, it needs to be treated before being discharged. In the treatment process, the flocculation and flotation process is required.

[0003] Among them, announcement number CN117945493B discloses a rapid flocculation flotation device, which includes a box body; four partitions are fixedly connected inside the box body; the four partitions divide the box body into five chambers, namely: a coagulation chamber, a flocculation chamber, a flotation chamber, a slag removal chamber, and a waste chamber; a notch is opened on the surface of the partition between the coagulation chamber and the flocculation chamber; a notch is opened on the surface of the partition between the flocculation chamber and the flotation chamber; a driving assembly is installed on the top of the flotation box; a pair of guide tubes are arranged inside the flotation chamber, and the driving assembly drives the guide tubes to move in the flotation chamber, so that the air bubbles sprayed from the guide tubes can be more evenly dispersed into the flotation chamber, making it easier for the flocculent waste residue in the wastewater to be adsorbed by the air bubbles and float to the surface, thereby accelerating the separation speed between the waste residue and the wastewater, and thus improving the purification efficiency of the wastewater.

[0004] However, in actual use, the device uses multiple chambers for flocculation and flotation, which results in a large equipment size, high site requirements, and a limited range of applicability. Furthermore, the separate operation of different processes leads to low wastewater treatment efficiency.

[0005] Therefore, it is necessary to invent an integrated flocculation and flotation device that addresses the characteristics of seaweed blanching wastewater to solve the above problems. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 5 The device shown is an integrated flocculation and flotation device for the characteristics of seaweed blanching wastewater. It includes a flocculation tank 1, a stirring motor 11 is fixedly installed at the lower end of the flocculation tank 1, and a spiral guide plate 12 is fixedly connected to the output end of the stirring motor 11. The spiral guide plate 12 is located at the center of the bottom wall of the flocculation tank 1. A mounting frame 2 is fixedly installed at the upper end of the flocculation tank 1. A flocculation and flotation component is provided on the surface of the mounting frame 2. The flocculation and flotation component includes a dosing tank 21, a rotating shaft 22, a rotating motor 25, a mounting plate 3, a cleaning net 32, an air guide pipe 4, a rotary joint 41, an air inlet pipe 42, a diverter pipe 43, and an air jet hole 44. The dosing tank 21 is fixedly installed on the left side of the upper surface of the mounting frame 2.

[0026] During its rotation, the spiral guide plate 12 generates a gradient shear force, which allows the reagent to react fully with the wastewater. At the same time, the dosing tank 21 can automatically dispense the reagent.

[0027] During use, wastewater is discharged into the flocculation tank 1 through the inlet pipe on the front side of the flocculation tank 1. Then, the dosing tank 21 adds the reagent into the wastewater. During the dosing process, the stirring motor 11 is started. The stirring motor 11 and the spiral guide plate 12 work together to stir the wastewater, so that the reagent and wastewater can be quickly mixed to form floc particles.

[0028] At the same time, the compressor compresses the air and sprays it out through the air inlet pipe 42, air guide pipe 4, diversion pipe 43 and multiple sets of jet holes 44, forming tiny bubbles inside the wastewater. The rotating motor 25 drives the air guide pipe 4 and diversion pipe 43 to rotate, dispersing the bubbles evenly inside the wastewater, so that the flocculation and bubbles can be fully combined, thereby improving the flocculation and flotation speed.

[0029] In addition, during the rotation of the rotating shaft 22, the cleaning net 32 ​​is driven to rotate close to the water surface, which quickly collects the flocculated particles after air flotation, so that the flocculation, air flotation and collection processes can be completed at the same time, further improving the equipment's wastewater treatment efficiency.

[0030] See Figures 2 to 4 The rotating shaft 22 is rotatably connected to the middle of the mounting bracket 2. A first bevel gear 23 is fixedly connected to the surface of the rotating shaft 22. The rotating motor 25 is fixedly installed on the right side of the upper surface of the mounting bracket 2. A second bevel gear 24 is fixedly connected to the output end of the rotating motor 25. The second bevel gear 24 meshes with the first bevel gear 23. The middle part of the air guide pipe 4 is coaxially fixedly connected to the inside of the rotating shaft 22. Multiple sets of "L"-shaped diverter pipes 43 are fixedly connected to the lower end of the air guide pipe 4. Multiple sets of jet holes 44 are opened on the surface of the lower half of the air guide pipe 4 and the surface of the diverter pipes 43. The rotary joint 41 is fixedly connected to the upper end of the air guide pipe 4. The lower end of the air inlet pipe 42 is rotatably connected to the rotary joint 41. A fixing bracket 26 is fixedly connected to the upper surface of the mounting bracket 2 at the left side of the rotating shaft 22. The air guide pipe 4 is rotatably connected to the upper end of the fixing bracket 26.

[0031] Specifically, the output end of the rotary motor 25 drives the second bevel gear 24 to rotate, the second bevel gear 24 drives the rotating shaft 22 to rotate through the first bevel gear 23, the rotating shaft 22 drives the air guide pipe 4 to rotate, and the air guide pipe 4 drives the multi-component flow pipe 43 to rotate together, thereby evenly dispersing the sprayed bubbles inside the wastewater. At the same time, during the rotation of the air guide pipe 4, it will rotate around the lower end of the air inlet pipe 42 through the rotary joint 41 to achieve uninterrupted air supply.

[0032] See Figure 3 and Figure 5 The lower end of the rotating shaft 22 is fixedly connected to two sets of mounting plates 3 on the left and right. Multiple sets of mounting grooves 31 are opened on the lower surface of the mounting plates 3. The mesh opening end of the cleaning net bag 32 is fixedly connected to a fixed frame 33. Multiple sets of mounting blocks 34 are fixedly connected to the upper end of the fixed frame 33. The mounting blocks 34 are engaged and fixed with the mounting grooves 31.

[0033] At the same time, as the rotating shaft 22 rotates, it will drive the mounting plates 3 on both sides to rotate together. The mounting plates 3 will drive the cleaning net 32 ​​on the lower side to rotate, and clean the flocculated particles floating on the surface of the wastewater.

[0034] In addition, the cleaning net 32 ​​and the mounting plate 3 can be quickly disassembled and assembled by the mounting clip 34 and the mounting slot 31, which facilitates the quick cleaning of the condensed flocculation inside the cleaning net 32.

[0035] The working principle of this utility model is as follows: The flocculant is added to the flocculant tank 1 through the dosing tank 21. The wastewater is stirred by the spiral guide plate 12, increasing the flocculant speed. Simultaneously, the air inlet pipe 42, air guide pipe 4, and diversion pipe 43 work together to spray high-pressure airflow outward through the jet nozzle 44, causing the flocculants to undergo air flotation. This integrates flocculant and air flotation, effectively reducing equipment size, improving equipment adaptability, and enhancing the convenience of installation and transportation. Furthermore, the rotary motor 25 drives the rotating shaft 22, air guide pipe 4, and diversion pipe 43 to rotate, evenly dispersing air bubbles into the wastewater, further increasing the flocculant and air flotation speed. The rotating shaft 22 also drives the cleaning nets 32 on both sides to rotate, quickly collecting the floating flocculants, further improving the equipment's integration. This allows the flocculant, air flotation, and collection processes to be completed simultaneously, further improving the equipment's wastewater treatment efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
