Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a PDMDAAC stirring device. Background Technology

[0002] PDMDAAC, short for "polydimethyldiallyl ammonium chloride", is a colorless to pale yellow viscous liquid. It is used as a cationic coagulant in wastewater treatment, mining, and mineral processing. It has the characteristics of strong coagulation, good hydrolytic stability, and non-gelling. It can be stirred during the production process of PDMDAAC.

[0003] There are some existing stirring devices. For example, the utility model patent document with authorization announcement number "CN212680974U" and patent name "A magnetic coagulant production reactor" discloses a PDMDAAC stirring device, which includes a reactor, a mixer, a mixer blade and a discharge pipe.

[0004] When it is necessary to stir the coagulant in the reactor, the operator drives the agitator blades to rotate and stir, and then the coagulant is discharged from the discharge pipe. However, some existing coagulant stirring devices only rely on the rotation of the agitator blades, resulting in poor stirring effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a PDMDAAC mixing device to solve the technical problem mentioned in the background art where some existing coagulant mixing devices only rely on the rotation of the mixer blades for mixing, resulting in poor mixing effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PDMDAAC stirring device includes a workbench with a reaction vessel fixed on it. The reaction vessel has a feed inlet at its top. Inside the reaction vessel, from top to bottom, there are a stirring frame, two stirring blades, and a dispersing roller. A rotating assembly connects the stirring frame, the two stirring blades, and the dispersing roller. The dispersing roller has multiple spiral blades. The bottom of the reaction vessel has a discharge pipe extending through the bottom of the workbench. The discharge pipe has a valve. A conveying assembly is located below the workbench. Multiple material buckets can be placed on the conveying assembly, and the multiple material buckets slide sequentially through the outlet of the discharge pipe along with the conveying assembly.

[0008] Working principle:

[0009] First, the operator rotates the stirring frame, two stirring blades, and dispersing roller by rotating the component, thereby stirring the PDMDAAC liquid in the reactor. Then, the conveying component moves the material tank on it. When the material tank moves to below the outlet pipe, the valve is opened to discharge the PDMDAAC liquid in the reactor into the material tank.

[0010] The beneficial effects of this utility model are as follows:

[0011] During use, the operator stirs the PDMDAAC liquid through the stirring frame, two stirring blades and the dispersing roller, which improves the dispersion and mixing effect of the PDMDAAC liquid. At the same time, the conveying component moves the material bucket, avoiding the operator from repeatedly picking up the material bucket and reducing the operator's workload. The valve also facilitates the control of the discharge pipe. Attached Figure Description

Detailed Implementation

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, a PDMDAAC stirring device includes a workbench 1, a reaction vessel 2 fixed on the workbench 1, a feed inlet 3 at the top of the reaction vessel 2, a stirring frame 4, two stirring blades 5 and a dispersing roller 6 arranged sequentially from top to bottom inside the reaction vessel 2, a rotating assembly connected between the stirring frame 4, the two stirring blades 5 and the dispersing roller 6, multiple spiral blades on the dispersing roller 6, a discharge pipe 7 extending through the bottom of the workbench 1 at the bottom of the reaction vessel 2, a valve 8 on the discharge pipe 7, a conveying assembly below the workbench 1, multiple material buckets 9 can be placed on the conveying assembly, and the multiple material buckets 9 slide sequentially through the opening of the discharge pipe 7 with the conveying assembly.

[0016] During the use of this utility model, the operator stirs the PDMDAAC liquid through the stirring frame 4, two stirring blades 5 and the dispersing roller 6, so that the PDMDAAC liquid is better dispersed and mixed. At the same time, the conveying component drives the material bucket 9 to move, avoiding the operator from repeatedly picking up the material bucket 9 and reducing the operator's workload. Meanwhile, the valve 8 facilitates the control of the discharge pipe 7.

[0017] like Figure 1 As shown, the rotating assembly includes a first motor 10, a rotating rod 11, and a third bevel gear 12. The first motor 10 is located at the top of the reactor 2, and a bent positioning component 13 is fixed between the first motor 10 and the reactor 2. A vertically downward rotating shaft 14 is fixed to the output end of the first motor 10 and rotates into the reactor 2. The bottom end of the rotating shaft 14 is located above the stirring blades 5. A stirring frame 4 is fixed to the rotating shaft 14, and multiple stirring rods 15 are fixed to the stirring frame 4. Multiple stirring blades 16 located inside the stirring frame 4 are fixed to the rotating shaft 14. A first pulley 17 located at the top outside the reactor 2 is fixed to the rotating shaft 14. The rotating rod 11 is rotatably located inside the reactor 2, and the rotating rod 11 is perpendicular to the rotating shaft 14. Two stirring blades 16 are fixed to the rotating shaft 14. A stirring blade 5 is fixed to a rotating rod 11. One end of the rotating rod 11 rotatably passes through the reactor 2. A first bevel gear 18 is fixed to one end of the rotating rod 11 that passes through the reactor 2. A second bevel gear 19 meshes with the first bevel gear 18. A vertical connecting rod 20 is fixed to the second bevel gear 19. A second pulley 21 is fixed to the top of the connecting rod 20. A first belt 22 is wound between the second pulley 21 and the first pulley 17. One end of a dispersing roller 6 rotatably passes through the reactor 2. A third bevel gear 12 is fixed to one end of the dispersing roller 6 that rotatably passes through the reactor 2. A fourth bevel gear 23 is fixed to the bottom end of the connecting rod 20. The third bevel gear 12 meshes with the fourth bevel gear 23. Figure 1 As shown, a positioning block 32 is fixedly mounted on the reactor 2, and a bearing 33 is fixedly mounted inside the positioning block 32. The connecting rod 20 passes vertically through the central hole of the bearing 33 and the two are fixedly connected. First, the operator starts the first motor 10. The output end of the first motor 10 drives the first pulley 17, the stirring frame 4, multiple stirring rods 15 and multiple stirring blades 16 to rotate through the rotating shaft 14. The first pulley 17 drives the second pulley 21 to rotate through the first belt 22, and then drives the second bevel gear 19 and the fourth bevel gear 23 to rotate through the connecting rod 20. During this process, the connecting rod 20 rotates within the bearing 33. The second bevel gear 19 drives the rotating rod 11 and the two stirring blades 5 to rotate through the first bevel gear 18 meshing with it. The fourth bevel gear 23 drives the dispersing roller 6 to rotate through the third bevel gear 12 meshing with it. This design has good linkage, and multiple mixing and stirring of PDMDAAC liquid in the reactor 2 can be achieved with only one first motor 10, resulting in better stirring effect and saving the use of a drive device.

[0018] like Figure 1 As shown, the conveying assembly includes two positioning plates 24 and a second motor 25. The two positioning plates 24 are positioned opposite each other below the workbench 1. A first rotating roller 26 and a second rotating roller 27 are rotatably arranged between the two positioning plates 24, and the first rotating roller 26 and the second rotating roller 27 are positioned opposite each other at both ends of the positioning plates 24. Multiple third rotating rollers 28 are also rotatably arranged between the two positioning plates 24, and the multiple third rotating rollers 28 are located between the first rotating roller 26 and the second rotating roller 27. The second motor 25 is located on the ground, and the output ends of the first rotating roller 26 and the second rotating roller 25 are fixedly connected. A conveyor belt 29 is wound between the first rotating roller 26 and the second rotating roller 27. The multiple third rotating rollers 28 are used to support the lower surface of the conveyor belt 29 that carries the material bucket 9. The material bucket 9 is placed on the conveyor belt 29 and moves with the rotation of the first rotating roller 26, the multiple third rotating rollers 28, and the second rotating roller 27. Figure 1 As shown, a cylinder 30 with a vertically downward-pointing telescopic end is fixed at the bottom of the workbench 1. A hanging scale 31 is fixed on the telescopic end of the cylinder 30, which is used to lift the material bucket 9 for weighing and receiving the material. When it is necessary to collect the mixed PDMDAAC liquid, the operator places the material bucket 9 on the conveyor belt 29 and starts the second motor 25. The output end of the second motor 25 drives the first rotating roller 26 to rotate. The first rotating roller 26 drives the second rotating roller 27 to rotate through the conveyor belt 29. During this process, the conveyor belt 29 moves the material bucket 9 on it. When the material bucket 9 moves to below the outlet pipe 7, the operator hangs the material bucket 9 on the hanging scale 31 and starts the cylinder 30. The telescopic end of the cylinder 30 drives the material bucket 9 to rise and separate from the conveyor belt 29 through the hanging scale 31. At this time, the valve 8 is opened to allow the PDMDAAC liquid to be discharged from the outlet pipe 7 and collected in the material bucket 9. When the crane scale 31 displays that the collected PDMDAAC liquid in the hopper 9 has reached the corresponding value, the valve 8 is closed and the hopper 9, which has completed the collection, is removed and placed back on the conveyor belt 29. This design facilitates quantitative collection of the hopper 9 and has a simple structure with good results.

[0019] like Figure 1 As shown, each positioning plate 24 is fixed with two mounting plates 34. Each mounting plate 34 has a support block 35 fixed at its bottom that abuts against the ground, and a support leg 36 fixed at its top that is connected to the workbench 1. This design facilitates the installation and support of the conveyor belt 29 and the workbench 1, allowing the material bucket 9 to move smoothly on the conveyor belt 29 to receive materials.

[0020] Working principle:

[0021] First, the operator starts the first motor 10 and pours the PDMDAAC liquid into the reactor 2 through the feed port 3.

[0022] During operation, the output of the first motor 10 drives the first pulley 17, the stirring frame 4, the multiple stirring rods 15 and the multiple stirring blades 16 to rotate via the rotating shaft 14. The first pulley 17 drives the second pulley 21 to rotate via the first belt 22, and then drives the second bevel gear 19 and the fourth bevel gear 23 to rotate via the connecting rod 20. During this process, the connecting rod 20 is rotated within the bearing 33. The second bevel gear 19 drives the rotating rod 11 and the two stirring blades 5 to rotate via the first bevel gear 18 meshing with it. The fourth bevel gear 23 drives the dispersing roller 6 to rotate via the third bevel gear 12 meshing with it.

[0023] Next, the operator places the material bucket 9 on the conveyor belt 29 and starts the second motor 25. The output end of the second motor 25 drives the first rotating roller 26 to rotate. The first rotating roller 26 drives the second rotating roller 27 to rotate through the conveyor belt 29. During this process, the conveyor belt 29 moves the material bucket 9 on it.

[0024] When the material bucket 9 moves to below the outlet of the discharge pipe 7, the operator hangs the material bucket 9 on the crane scale 31 and starts the cylinder 30. The extension end of the cylinder 30 drives the material bucket 9 to rise and separate from the conveyor belt 29 through the crane scale 31. At this time, the valve 8 is opened to allow the PDMDAAC liquid to be discharged from the discharge pipe 7 and collected in the material bucket 9.

[0025] When the crane scale 31 displays that the PDMDAAC liquid collected in the hopper 9 has reached the corresponding value, the valve 8 is closed and the hopper 9, which has completed the collection, is removed and placed back on the conveyor belt 29.
