[0001] This utility model relates to the field of laboratory wastewater treatment, and in particular to a laboratory wastewater purification device that is easy to install. Background Technology

[0002] In the field of laboratory wastewater treatment, traditional purification equipment generally suffers from technical bottlenecks such as complex installation, low mixing efficiency, and incomplete solid-liquid separation. Conventional stirring devices mostly use unidirectional rotating blades, which have limited mixing effects, and are prone to incomplete reactions, especially for wastewater with high viscosity or suspended solids.

[0003] To address the aforementioned issues, this patent proposes a wastewater purification device that enables rapid installation and deployment, three-dimensional stirring to enhance the reaction, and integrated operation of dynamic centrifugal separation and filtration. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides a conveniently installed laboratory wastewater purification device, including a purification tank 1. A support leg 2 is connected to the outer side of the lower end of the purification tank 1. Inlet pipes 3 are connected to both the front and rear sides of the upper end of the purification tank 1, and threads are provided on the outer wall of the openings of both inlet pipes 3. A stirring motor 4 is located at the center of the lower end of the purification tank 1. Multiple stirring blades 5 are installed inside the purification tank 1. A water outlet pipe 6 is connected to the front side of the lower end of the purification tank 1, and a filter 7 is connected to the other end of the water outlet pipe 6. Threads are provided on the outer wall of the opening at the front end of the filter 7. During the purification of laboratory wastewater, the purification tank 1 is supported at the bottom by the support leg 2. Wastewater pipes, treatment liquid pipes, and outlet water pipes are connected through the threads on the outer wall of the openings of the two inlet pipes 3 and the filter 7. The purification equipment is quickly installed via pipelines. Wastewater is introduced into the purification tank 1 through the wastewater pipeline and inlet pipe 3, while the treatment liquid is introduced into the purification tank 1 through the treatment liquid pipeline and another inlet pipe 3. At this time, the stirring motor 4 is electrically connected to an external power source via wiring harness and is turned on. The stirring motor 4 drives multiple stirring blades 5 to rotate inside the purification tank 1, mixing the wastewater and treatment liquid evenly and generating a reaction. This neutralizes harmful substances in the wastewater and causes the reaction products to aggregate. The aggregated reaction products are thrown to the outside of the purification tank 1 by the centrifugal force of the mixture, thereby separating the reaction products from the treated water. The separated treated water is introduced into the filter 7 through the water outlet pipe 6 for filtration and then discharged through the drainage pipe.

[0027] Preferably, the purification tank 1 is provided with a separation baffle 8, which is fixedly connected to the inner walls of the upper and lower ends of the purification tank 1 and forms a collection chamber between the separation baffle 8 and the purification tank 1. The separation baffle 8 has multiple separation holes 9, which are connected between the separation baffle 8 and the collection chamber. The lower left side of the collection chamber is connected to a sewage discharge pipe 10, which is connected to the lower left side outer wall of the purification tank 1. The sewage discharge pipe 10 has threads on the outer wall of the opening. During the separation of the collected reaction products and the treated water, the reaction products are thrown to the outside of the purification tank 1 and adhere to the inner wall of the separation baffle 8. They are then introduced into the collection chamber between the separation baffle 8 and the purification tank 1 through the multiple separation holes 9 for collection, thereby separating the reaction products and the treated water. Finally, the water is discharged through the sewage discharge pipe 10. The sewage discharge pipe 10 can be connected to a sewage pipe through the threads on the outer wall of the opening, and the collected reaction products can be discharged through the sewage pipe.

[0028] Preferably, the upper end of the stirring motor 4 is fixedly connected to a rotating bushing 11 via a transmission shaft. The rotating bushing 11 is rotatably connected inside the purification tank 1 and located between multiple stirring blades 5. The upper end of the rotating bushing 11 is inserted into a fixed shaft 12, and the upper end of the fixed shaft 12 is connected to the center of the upper inner wall of the purification tank 1. Multiple linkage connectors 13 are rotatably connected inside the cylindrical outer wall of the rotating bushing 11. The linkage connectors 13 are connected to the center of one end of the stirring blade 5 near the rotating bushing 11, and the stirring blade 5 is rotatably connected to the rotating bushing 11 via the linkage connectors 13. During the stirring of the mixture, the stirring motor 4 drives the multiple linkage connectors 13 to rotate via the rotating bushing 11, and drives the multiple stirring blades 5 to rotate inside the purification tank 1 via the multiple linkage connectors 13. This allows the multiple stirring blades 5 to stir the mixture inside the purification tank 1 in a horizontal direction, improving the mixing efficiency of wastewater and treatment liquid and improving the reaction efficiency.

[0029] Preferably, the end of the linkage connector 13 furthest from the stirring blade 5 is connected to a helical gear 14, which is rotatably connected inside the purification tank 1. Multiple toothed grooves 15 are formed on the outer wall of the cylindrical fixed shaft 12, and the multiple helical gears 14 are rotatably connected inside these grooves. Helical tooth surfaces 16 are provided on the lower inner walls of the multiple toothed grooves 15, and the multiple helical gears 14 mesh with the multiple helical tooth surfaces 16. While the linkage connector 13 drives the stirring blade 5 to rotate around the rotating sleeve 11, the linkage connector 13 also drives the helical gears 14 inside the rotating sleeve 11. Rotating around the axis of the fixed shaft 12, since the fixed shaft 12 is fixedly connected to the inner wall of the upper end of the purification tank 1, and the helical gear 14 meshes with the helical tooth surface 16 on the inner wall of the lower end of the tooth groove 15, the helical gear 14 will roll on the upper end of the helical tooth surface 16 while rotating around the axis of the fixed shaft 12, so that the helical gear 14 rotates axially, and drives the stirring blade 5 to rotate axially through the linkage connector 13, so that the stirring blade 5 can perform local axial stirring of the mixture, further improving the mixing efficiency of wastewater and treatment liquid, and improving the wastewater purification efficiency.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
