Description

Technical Field

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

[0002] In water treatment, flocculants are generally used to treat particulate matter in the water, causing a large number of particles to combine and settle. In order for the flocculant to work efficiently, a mixing device is needed to stir the water and flocculant in the sedimentation tank to increase the contact between the flocculant and the substances in the water.

[0003] Most common mixing devices have simple structures, simply using a drive unit to rotate the mixing blades to achieve a mixing effect. However, these common mixing structures are generally fixed in position, meaning they can only operate at a single location, leading to uneven mixing. While the mixing effect is high at the point of contact with the mixing structure, the surrounding water, further away from it, experiences limited mixing. Furthermore, when adding flocculants, the pre-mixed flocculant is usually added directly, often at a single location. This results in uneven flocculant distribution, requiring time for diffusion, or manual control involving moving the equipment to multiple locations, placing significant demands on workers and making the flocculant's effectiveness inconvenient. Additionally, during mixing, the agitation of the water's interior, combined with the reaction of the flocculant with the water, easily generates numerous air bubbles. These bubbles rise to the surface, affecting the sedimentation of precipitates and impacting water treatment efficiency. Utility Model Content

[0030] Please see Figure 1-5 A flocculant mixing device for water treatment includes a sedimentation tank 1, a support frame 2 at the upper end of the sedimentation tank 1, a support plate 3 on the support frame 2, multiple sets of support plates 3 and slidingly cooperating with the support frame 2, a stirrer 4 on the support plate 3, a drive motor 5 at one end of the support frame 2, an eccentric wheel 6 at the output end of the drive motor 5, a drive rod 7 rotatably connected to the eccentric wheel 6, a moving rod 8 rotatably connected to one end of the drive rod 7, and the moving rod 8 fixedly connected to the support plate 3.

[0031] The sedimentation tank 1 is equipped with a feeding box 9 at one end, and a feeding pump 10 at the other end. The support frame 2 is equipped with a diversion pipe 11, and a feeding pipe 12 is provided on the diversion pipe 11. Multiple sets of feeding pipes 12 are provided and evenly distributed on the diversion pipe 11. The feeding pump 10 is coordinated with the diversion pipe 11.

[0032] In this embodiment, the sedimentation tank 1 provides space for wastewater sedimentation. With the support of the support frame 2, the support plate 3 supports the agitator 4. The drive motor 5 is started, which controls the eccentric wheel 6 to rotate. The eccentric wheel 6 moves the drive rod 7, which in turn moves the moving rod 8 repeatedly. This causes the support plate 3 to move the agitator 4 repeatedly. Through the cooperation of multiple moving agitators 4, efficient stirring is carried out.

[0033] More specifically, an appropriate amount of flocculant and water are added to the feeding tank 9 to mix the flocculant and water. Then, the feeding pump 10 is activated to make the flocculant solution flow to the diversion pipe 11. The solution is then diverted through the diversion pipe 11, allowing it to flow out from multiple feeding pipes 12 and be evenly added into the sedimentation tank 1 from multiple locations for mixing.

[0034] Please see Figure 3 As one method of foam cleaning: the support plate 3 is provided with lower extension rods 13 at both ends, the lower end of the lower extension rods 13 is provided with contact plates 14, and the contact plates 14 are provided with defoaming puncture 15.

[0035] Specifically, when the support plate 3 moves, it moves along with the contact plate 14 through the connection and support of the lower extension rod 13, so that the contact plate 14 moves on the water surface. When the contact plate 14 moves, it will contact the air bubbles on the water surface through the defoamer 15, puncture the air bubbles, reduce the floating of foam on the water surface, and improve the sedimentation effect.

[0036] Please see Figure 3 As a further implementation of foam cleaning: the support plate 3 is provided with sliding frames 16 at both ends, the lower extension rod 13 is slidably engaged with the sliding frame 16, the sliding frame 16 is provided with positioning bolts 17, and the positioning bolts 17 are threadedly engaged with the sliding frame 16.

[0037] Specifically, during water treatment, the lower extension rod 13 is adjusted according to the water level. The positioning bolt 17 is loosened, and the lower extension rod 13 is controlled to slide along the sliding frame 16 so that the contact plate 14 moves to a suitable height. Then, the positioning bolt 17 is tightened to fix the lower extension rod 13.

[0038] Please see Figure 2 and Figure 3 As a further embodiment of the support plate: the support plate 3 is provided with support pulleys 18 at both ends, and the support frame 2 is provided with support grooves 19 at both ends. The support plate 3 cooperates with the support grooves 19 through the support pulleys 18.

[0039] Specifically, the two ends of the support plate 3 are located in the support groove 19, and the support pulley 18 contacts the support groove 19 to provide support, so that the support plate 3 remains stable on the support frame 2, and the support pulley 18 rotates when the support plate 3 moves, so that the movement of the support plate 3 remains smooth.

[0040] Please see Figure 2 and Figure 3 As a further embodiment of the support plate: the support frame 2 is provided with a guide rod 20, and the support plate 3 is provided with a guide groove 21, which slides with the guide rod 20.

[0041] Specifically, when the support plate 3 moves, the guide groove 21 cooperates with the guide rod 20, and under the guidance and restriction of the guide rod 20, the groove of the guide rod 20 slides along the guide rod 20, ensuring the stability of the support plate 3.

[0042] Please see Figure 2As a further embodiment of the stirrer: the stirrer 4 includes a stirring motor 22, a stirring screw 23 and stirring blades 24. The stirring motor 22 is mounted on the upper end of the support plate 3. The stirring screw 23 is rotatably engaged with the support plate 3 and is engaged with the drive end of the stirring motor 22. Multiple sets of stirring blades 24 are provided and are evenly arranged on the stirring screw 23.

[0043] Specifically, the stirring motor 22 provides power, causing the stirring screw 23 to rotate with the stirring blades 24, providing a stirring effect and enabling the flocculant to dissolve efficiently in the water.

[0044] Please see Figure 5 As a further embodiment of the feeding box: the feeding box 9 is equipped with a mixing motor 25, and the feeding box 9 is equipped with a mixing rod 26. The mixing motor 25 cooperates with the mixing rod 26, and the mixing rod 26 is equipped with mixing blades 27.

[0045] Specifically, by controlling the operation of the mixing motor, the mixing motor drives the mixing rod 26 to rotate, thereby causing the mixing rod 26 to rotate with the mixing blades 27, which stirs the flocculant and water, so that the flocculant is more evenly mixed into the water.

[0046] Please see Figure 4 As a further embodiment of the sedimentation tank: an additional motor 28 is provided at the outer end of the sedimentation tank 1, and an agitator impeller 29 is provided inside the sedimentation tank 1, with the agitator impeller 29 cooperating with the additional motor 28.

[0047] Specifically, an additional motor 28 provides power to rotate the impeller 29, which agitates the water in the sedimentation tank 1, causing the water to flow towards the center, providing a richer flow direction and improving the agitation effect.

[0048] In summary, during the use or operation of the overall equipment:

[0049] When using the equipment, connect it to an external power source. The sedimentation tank 1 provides space for wastewater sedimentation. Add an appropriate amount of flocculant and clean water to the feeding tank 9. Control the mixing motor to drive the mixing rod 26 to rotate, which in turn rotates the mixing blades 27 to stir the flocculant and clean water, making the flocculant more evenly mixed into the clean water. Then, the feed pump 10 operates to make the flocculant solution flow to the diversion pipe 11. Guided by the diversion pipe 11, the flocculant solution is diverted and flows out from multiple feeding pipes 12, and is evenly added into the sedimentation tank 1 from multiple locations for stirring and mixing of the flocculant.

[0050] During mixing, the support plate 3 supports the stirrer 4 under the support of the support frame 2. The drive motor 5 is started, controlling the eccentric wheel 6 to rotate. The eccentric wheel 6 moves the drive rod 7, which in turn moves the moving rod 8 repeatedly. This causes the support plate 3 to move repeatedly along with the stirrer 4. Both ends of the support plate 3 are located in the support groove 19, and the support pulley 18 contacts the support groove 19, providing support and ensuring the support plate 3 remains stable on the support frame 2. The support pulley 18 rotates as the support plate 3 moves, ensuring smooth movement. During movement, the guide groove 21 cooperates with the guide rod 20, allowing the guide rod 20 to slide along its groove, ensuring the stability of the support plate 3. Multiple moving stirrers 4 work together, and the stirring motor 22 provides power to drive the stirring screw 23. The stirring blades 24 rotate to perform efficient stirring, allowing the flocculant to dissolve efficiently in the water. Furthermore, an additional motor 28 powers the stirring impeller 29 to agitate the water in the sedimentation tank 1, causing it to flow towards the center and providing a more varied flow direction, thus improving the stirring effect. Additionally, as the support plate 3 moves, the lower extension rod 13 connects and supports it, moving the contact plate 14 along with it. As the contact plate 14 moves, it contacts and breaks bubbles on the water surface via the defoamer 15, reducing foam floating on the water surface and improving subsequent sedimentation. Loosening the positioning bolts 17 allows adjustment of the lower extension rod 13 according to the water level, controlling its sliding along the sliding frame 16 to move the contact plate 14 to a suitable height. Finally, tightening the positioning bolts 17 fixes the lower extension rod 13, adapting to different water volumes.

[0051] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
