[0002] In the process of sludge treatment, the use of purifying agents is an indispensable link. However, there are many problems in the preparation of traditional sludge purifying agents.

[0038] For a further optimized solution, the stirring assembly includes two stirring paddles. Each stirring paddle includes a rotating shaft 14. At the top and bottom of the rotating shaft 14, a first stirring disc 15 and a second stirring disc 16 are respectively sleeved and fixedly connected. Between the first stirring disc 15 and the second stirring disc 16, there are several layers of movable stirring members. The stirring members include grid blades 17. A number of grid blades 17 are provided and are equidistantly arranged on the side surface of the rotating shaft 14. Adjacent grid blades 17 are staggered up and down.

[0039] For a further optimized solution, the first driving assembly includes a driving rod 21. On the opposite side surfaces at one end of the driving rod 21, a through oblong sliding hole 22 is provided. A sliding column 23 is penetrated and slidably connected in the sliding hole 22. At both ends of the sliding column 23, fixing blocks are respectively fixedly connected. The fixing blocks are fixedly connected to the top surface of the cross beam 18, realizing the transmission connection between the driving rod 21 and the cross beam 18. The other end of the driving rod 21 penetrates through the stirring cylinder 1 and is hinged to a telescopic member 24. The middle part of the driving rod 21 is hinged to the stirring cylinder 1.

[0041] To further optimize the solution, two hinge holes 25 are provided on the side of the mixing drum 1, and the hinge holes 25 are hinged to the middle part of the driving rod 21; an elastic rubber strip 26 is fixedly connected in the hinge hole 25; the rubber strip 26 covers the hinge hole 25, and the hinge hole 25 provides running space for the driving rod 21 during the swinging process.

The vibrator 27 is arranged between two adjacent stirring components, which can not only make up for the stirring dead angle of the stirring component, but also improve the water solubility of polyacrylamide through the action of ultrasonic waves.

[0043] Furthermore, the connection block 28 can be used to connect the vibrator 27 to an external power supply, and to fix the vibrator 27 to the mixing drum 1 .

[0044] To further optimize the solution, the stirring members of the two stirring assemblies are set in opposite flipping directions. By setting the flipping directions of the two stirring assemblies in opposite directions, the two stirring members can continuously stir the mixture to impact each other, further improving the contact between water and polyacrylamide in the mixture, and under the action of dimethyldiallylammonium chloride, the polyacrylamide is dissolved in the water to the maximum extent and the undissolved polyacrylamide forms a hydrate with the saturated polyacrylamide aqueous solution, thereby enhancing the water treatment effect per unit volume of the purifier.

[0045] An embodiment of the present invention:

[0046] A concentrated sludge purifier includes polyacrylamide, water and dimethyldiallyl ammonium chloride; the ratio is: the mass percentage of polyacrylamide is 0.1%-0.3%; the mass percentage of water is 99.7%-99.85%; the mass percentage of dimethyldiallyl ammonium chloride is 0.05%-0.15%. The polyacrylamide is a cationic polyacrylamide; and the dimethyldiallyl ammonium chloride is a dimethyldiallyl ammonium chloride polymer. The product of the above formula after being processed by the stirring processing device of the present application can be further added with polyacrylamide powder with a volume ratio of 20%-80%, and then stirred. The speed of the stirring paddle is set to 0.5-10RPM. The stirring can be used to gradually supersaturate the polyacrylamide powder into the purifier and evenly disperse it throughout the purifier to achieve the concentration of the purifier. Improve the purifying power of the purifier per unit volume.

[0047] The working process of this embodiment is as follows:

[0048] First, the powder mixed with polyacrylamide and dimethyldiallyl ammonium chloride according to the ratio is first put into the material ring 7. At this time, the mesh holes of the first screen 5 and the second screen 6 are not aligned at all, and the mixed powder can be completely placed in the inner cavity of the material ring 7. Then, water is injected into the mixing drum 1 through the water inlet pipe 2 using the water source, and the water flow is sprayed into the mixing drum 1 through the water spray hole. At this time, the second motor 9 is started, and the second motor 9 drives the gear 10 to drive the material ring 7 to rotate. The material ring 7 drives the first screen 5 and the second screen 6 to rotate relative to each other. Because the bottom surface of the first screen 5 and the top surface of the second screen 6 fit and slide, the mesh holes of the two will be intermittently aligned and staggered, and the powder placed in the material ring 7 will continuously leak into the mixing drum 1. During the process, the spring 11 fixedly connected to the output shaft of the second motor 9 rotates, and the rotation of the spring 11 drives the vibration ball 12 to knock the driving column 8 to achieve the vibration of the material ring 7, so as to prevent the accumulation of powder in the material ring 7 and the difficulty of feeding.

[0049] At this time, the powder is impacted by the water flow during its falling process, and gradually fills the inner cavity of the mixing drum 1. At this time, the telescopic member 24 is started, and the telescopic member 24 drives the driving rod 21 to swing around the fulcrum as the axis. One end of the driving rod 21 is tilted, and the sliding column 23 is pulled to pull up the beam 18. The telescopic member 24 of the other stirring component synchronously pulls the beam 18 in the opposite direction, thereby realizing the reverse movement of the rotating shafts 14 of the two stirring components, which drives the grating blades 17 and the rotating shaft 14 to deflect, drives the mixture to impact and shear each other, and improves the dissolution efficiency of water and powder.

[0050] The first stirring disc 15 and the second stirring disc 16 located at the top and bottom of the rotating shaft 14 stir the materials at the top and bottom of the mixture respectively to prevent the mixture from settling in a dead corner, resulting in uneven mixing of the materials.

[0051] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
