Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sludge and flocculant mixing device that improves stirring intensity. Background Technology

[0002] In the process of treating sludge in wastewater, it is usually necessary to mix it with flocculants. The main function is to improve the floc structure of the sludge, increase its settling and dewatering performance. Specifically, flocculants interact with colloids in the sludge, causing sludge particles to aggregate into larger flocs. These flocs are not only easier to separate from the water, but also increase the settling speed of the sludge, thus facilitating rapid settling. In addition, flocculants can also increase the adsorption effect of the sludge, enabling it to adsorb more suspended solids and impurities during the settling process, further improving the water purification effect.

[0003] Currently, a single stirring rod is typically used to mix sludge and flocculant during the mixing process. However, due to the limited mixing range of a single stirring rod, the flocculant cannot be fully mixed with the sludge in a short time, resulting in a longer mixing time and affecting the efficiency of the treatment process. Utility Model Content

[0004] The purpose of this invention is to provide a sludge and flocculant mixing device that improves the mixing strength, effectively enhancing the mixing effect between sludge and flocculant, ensuring rapid separation of sludge and water, and thus improving the efficiency of the treatment operation.

[0013] 1. This utility model, through the configuration of a drive motor, a rotating shaft, and stirring blades, enables the mixing of flocculant and sludge inside the treatment tank. Under the action of the flocculant, the mud and water in the sludge are quickly separated. Furthermore, through the coordinated action of the rotating shaft, first pulley, belt, second pulley, rotating rod, rotating disk, and arc-shaped blades, the flocculant and sludge are further agitated and mixed at different positions at the bottom of the treatment tank. This effectively improves the mixing effect between the flocculant and sludge, ensuring that the mud and water in the sludge can be fully flocculated and separated in a short time, thereby greatly improving the efficiency of the treatment operation.

A rotating shaft 10 is fixedly installed at the output end of the drive motor 8.

An arc-shaped blade 18 is fixedly connected to the top of the rotating disk 19.

[0025] In this technical solution, the combination of drive motor 8, rotating shaft 10, and stirring blades 17 enables the mixing of flocculant and sludge inside treatment tank 1. Under the action of flocculant, the mud and water in the sludge are quickly separated. Furthermore, the combined action of rotating shaft 10, first pulley 11, belt 16, second pulley 12, rotating rod 21, rotating disk 19, and arc-shaped blades 18 further agitates and mixes the flocculant and sludge at different locations at the bottom of treatment tank 1. This effectively improves the mixing effect between flocculant and sludge, ensuring that the mud and water in the sludge can be fully flocculated and separated in a short time, thereby greatly improving the efficiency of the treatment operation.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 1 As shown, a medicine tank 7 is fixedly connected to the top of the outer surface of the fixture 9 and behind the drive motor 8. A filling pipe is fixedly connected to the top of the medicine tank 7. A delivery pump 6 is fixedly installed on the right side of the medicine tank 7 through a pipe. A drug delivery nozzle 5 is fixedly installed between the output end of the delivery pump 6 and the top of the inner cavity of the fixture 9 through a pipe.

[0028] In this technical solution, the flocculant required for purification treatment can be stored in the reagent tank 7. The flocculant inside the reagent tank 7 can be extracted and transported into the treatment tank 1 during the treatment process by the delivery pump 6 and the dosing nozzle 5, thereby achieving the effect of automatic flocculant feeding and bringing great convenience to the work of personnel.

[0029] Example 3:

[0030] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, support shafts 15 are fixedly connected to both ends of the bottom of the outer surface of the treatment tank 1. The surface of the support shafts 15 is movably connected to guide wheels 14 via bearings. The surface of the belt 16 is connected to the middle end of the guide wheels 14. Support blocks 2 are fixedly connected to all four sides of the bottom of the outer surface of the treatment tank 1. A protective frame 13 is fixedly connected to the bottom of the outer surface of the treatment tank 1. An input pipe 4 is fixedly connected to the upper right side of the treatment tank 1. A first control valve is fixedly connected to the surface of the input pipe 4. A discharge pipe 3 is fixedly connected to the lower end of the front surface of the treatment tank 1. A second control valve is fixedly installed on the surface of the discharge pipe 3. A second rubber ring 22 is fixedly connected to the middle end of the bottom of the treatment tank 1. The lower end of the rotating shaft 10 is movably connected to the surface of the second rubber ring 22. A first rubber ring 20 is fixedly connected to the bottom of the treatment tank 1. There are three first rubber rings 20. The middle end of the rotating rod 21 is movably connected to the surface of the first rubber ring 20. The stirring blade 17 is inclined at an angle of 75 degrees.

[0031] In this technical solution, the support shaft 15 and guide wheel 14 guide the belt 16 while increasing the wrap angle between the belt 16 and the first pulley 11, preventing slippage due to the small wrap angle. The support block 2 supports the bottom of the treatment tank 1. The protective frame 13 protects the belt 16. The inlet pipe 4, the first control valve, the outlet pipe 3, and the second control valve facilitate the input and discharge of sludge into and out of the treatment tank 1. The first rubber ring 20 and the second rubber ring 22 improve the sealing effect between the rotating rod 21 and the treatment tank 1, and between the rotating shaft 10 and the treatment tank 1, respectively.

[0032] The working principle of this utility model is as follows: The treatment tank 1 holds the sludge to be treated. After the flocculant is added, the drive motor 8 is started, which drives the rotating shaft 10 and the stirring blades 17 to rotate. The rapid rotation of the stirring blades 17 stirs the sludge and the added flocculant inside the treatment tank 1, allowing them to mix. Under the action of the flocculant, the mud and water in the sludge are quickly separated. During the rotation of the rotating shaft 10, the first pulley 11 rotates. The rotation of the first pulley 11, via the belt 16, simultaneously drives three sets of second pulleys 12, the rotating rod 21, the rotating disk 19, and the arc-shaped blades 18 to rotate rapidly. The rotating disk 19 and the arc-shaped blades 18, under the action of rotation, agitate and mix the flocculant and sludge at different positions at the bottom of the treatment tank 1, effectively improving the mixing effect between the flocculant and sludge. This ensures that the mud and water in the sludge can be fully flocculated and separated in a short time, thus greatly improving the efficiency of the treatment operation.
