Description

Technical Field

[0001] The utility model relates to the technical field of flocculant processing, in particular to a flocculant mixing device for research and development. Background Art

[0002] Flocculants are chemical agents used in water and sewage treatment processes. They promote the aggregation of suspended particles and other impurities in water into larger flocs (i.e., "flocculation"). Once these flocs settle or are filtered, they effectively remove pollutants such as suspended matter, colloids, and color from the water, achieving the goal of water purification or sewage treatment.

[0003] In order to improve the performance of the flocculant, multiple additives are added in appropriate proportions for mixing during the research and development stage and during the production of the flocculant. The existing utility model patent with publication number CN218654047U, entitled "A Flocculant Mixing System", includes a stirring box, a stirring assembly and a mounting bracket. A water inlet is provided on the side of the stirring box, an opening and closing assembly is provided in the stirring box, and the opening and closing assembly is fixedly connected to a part of the stirring assembly. The opening and closing assembly includes a driven turntable, a calibration hole is provided on the driven turntable, and a plurality of inclined baffles are fixed to the side of the driven turntable, one end of the inclined baffle is abutted against the inner wall of the stirring box, and a drainage gap is formed between two adjacent inclined baffles.

[0004] The above-mentioned device has excellent production capacity in mass production, but it takes up a lot of space when used in the research and development stage or in the laboratory. In addition, a large amount of raw materials need to be added when using this device to achieve a good mixing effect, which is not conducive to research and development experiments. Most of the existing common laboratories use manual stirring for mixing, but this mixing method is inefficient and has poor fusion. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a flocculant mixing device for research and development, which is used to solve the technical problems in the background technology that the existing mixing device is not used in the research and development stage, and the existing mixing method has low efficiency and poor fusion effect.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A flocculant mixing device for research and development includes a workbench, a hollow support column is provided on the workbench, the support column extends vertically upward, a mixing disk is fixedly provided on the top of the support column, a connecting shell is rotatably provided at the axis above the mixing disk, a driving assembly for driving the connecting shell to rotate is provided on the workbench, a scraper is provided on the connecting shell for slidingly abutting against the side wall of the mixing disk, and a mixing piece for mixing and stirring is provided at the bottom of the connecting shell.

[0008] Working principle:

[0009] This device is a flocculant mixing device for research and development, which is mainly used to mix and stir the flocculants during research and development experiments.

[0010] When in use, just place the well-proportioned flocculant raw materials and the mixed liquid into the mixing tray at the same time, and then drive the connecting shell to rotate through the driving component. When the connecting shell rotates, it will also drive the mixing piece at the bottom of the connecting shell to rotate and stir the material in the mixing tray. When the connecting shell rotates, it will also drive the scraper fixedly connected to the connecting shell to slide along the inner wall of the mixing tray to scrape off the material adhering to the inner wall of the mixing tray.

[0011] Beneficial effects obtained:

[0012] First, a driving assembly is provided, which can effectively drive the connecting shell and the mixing piece to rotate through the driving assembly, thereby facilitating the mixing of materials in the mixing tray, saving the setting of different power sources, reducing the occupied space of the device, and facilitating the device to carry out small batch research and development mixing.

[0013] Secondly, a scraper is provided, which can effectively drive the scraper to rotate along the inner wall of the mixing disk through the rotation of the connecting shell, and the scraper can effectively scrape off the material on the inner wall of the scraper through the sliding contact with the inner wall of the mixing disk. This not only improves the mixing efficiency of the materials, but also makes it easier for subsequent personnel to clean the mixing disk. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] Reference Figure 1 and Figure 2 This device is a flocculant mixing device for research and development, comprising a workbench 1, on which is provided a hollow support column 2 extending vertically upward. A mixing tray 3 with an open top is fixed to the top of the support column 2. The mixing tray 3 is made of a transparent material, making it easy for the operator to observe. A discharge hole 18 is provided at the bottom of the mixing tray 3, and a filter 19 is provided in the discharge hole 18. A valve 20 connected to the discharge hole 18 is provided at the bottom of the mixing tray 3. A measuring cup placement rack 21 is provided on the workbench 1 and below the discharge hole 18. A hose is provided at the bottom of the valve 20, which can be used to extend into the measuring cup to collect the mixed material.

[0022] like Figure 2 As shown, a connecting shell 4 is rotatably provided at the axis center above the mixing disk 3, and a driving assembly is provided on the workbench 1 for driving the connecting shell 4 to rotate along the axis center of the mixing disk 3. The driving assembly includes a fixed frame 6, a driving motor 7, and a driving rod 8. The fixed frame 6 is fixedly mounted on the workbench 1, the driving motor 7 is fixedly mounted on the top of the fixed frame 6, and the driving rod 8 is fixedly mounted on the output end of the driving motor 7. The other end of the driving rod 8 passes vertically downward through the fixed frame 6 and is fixedly connected to the top of the connecting shell 4. This arrangement can effectively drive the driving rod 8 to rotate through the rotation of the driving motor 7, and drive the connecting shell 4 connected to the driving rod 8 to rotate. A scraper 5 is provided on the connecting shell 4 for sliding against the side wall of the mixing disk 3. When the connecting shell 4 rotates, it further drives the connected scraper 5 to rotate, thereby scraping the material on the side wall of the mixing disk 3.

[0023] like Figure 2 and Figure 4 As shown, the bottom of the connecting shell 4 is provided with a mixing piece for mixing and stirring, the support column 2 is fixed with a support rod 9, the support rod 9 extends vertically upward, the top of the support rod 9 is provided with a support block 10, the support block 10 is fixedly sleeved with a first gear 11, the bottom of the connecting shell 4 is fixed with a gear plate 12 that is coaxial with the first gear 11 and has teeth on the inside, the first gear 11 and the gear plate 12 are meshed with a second gear 13, and the mixing piece is fixedly connected to the second gear 13. Figure 2 and Figure 3As shown, the mixing element includes a connecting rod 14 and a plurality of stirring rods 15. The connecting rod 14 is coaxial with the second gear 13 and is fixedly connected to the second gear 13. The plurality of stirring rods 15 are fixedly mounted on the side wall of the connecting rod 14. This arrangement can effectively drive the second gear 13 to revolve around the first gear 11 through the rotation of the connecting shell 4. Because the first gear 11 is fixed, the second gear 13 rotates while revolving. At the same time, the connecting rod 14 drives the plurality of stirring rods 15 at the bottom to rotate and stir, thereby improving the stirring efficiency of the stirring rods 15. A protective shell 16 is provided on the outer wall of the support rod 9. An avoidance hole 17 for the passage of the mixing element is formed between the connecting shell 4 and the protective shell 16.

[0024] Working principle:

[0025] When in use, it is only necessary to place the well-proportioned flocculant raw materials and the mixed liquid into the mixing disk 3 at the same time, and then the driving rod 8 is driven to rotate by the rotation of the driving motor 7, and the connecting shell 4 connected to the driving rod 8 is driven to rotate. The rotation of the connecting shell 4 drives the second gear 13 to revolve around the first gear 11 as the axis. Because the first gear 11 is fixed, the second gear 13 rotates while revolving. At the same time, the connecting rod 14 drives the several stirring rods 15 at the bottom to rotate and stir. When the connecting shell 4 rotates, it will also drive the scraper 5 fixedly connected to the connecting shell 4 to slide along the inner wall of the mixing disk 3 to scrape off the material adhering to the inner wall of the mixing disk 3.
