Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, and in particular to a wastewater purification device for biological research and development. Background Technology

[0002] Biological research and development, or biotechnology research and development, refers to the technological approach that uses modern life sciences as a foundation, combines the scientific principles of other basic sciences, and employs advanced scientific and technological means to modify organisms or process biological raw materials according to a pre-designed plan in order to produce products needed by humans or achieve certain purposes. In addition, a certain amount of wastewater will be generated during the research and development process, and improper wastewater treatment can easily cause environmental pollution.

[0003] Therefore, a wastewater purification device for biological research and development, with publication number CN214360456U, involves moving the base plate and U-shaped support to a designated position, closing the drain valve and sewage valve, adding wastewater to be treated into one conical cylinder, and adding flocculation and sedimentation agent into another conical cylinder. The motor drives the spiral shaft to rotate synchronously, which in turn drives the spiral blades and scraper to rotate synchronously, and simultaneously drives the rotating shaft and stirring blades to rotate synchronously, starting the flocculation, mixing and stirring of the wastewater. After stirring is completed, the lifting plate rises, causing the limiting hole to slide along the limiting rod, and causing the rotating shaft to rise along the rotating shaft hole. The circular column disengages from the circular groove, and the square column disengages from the square groove, and is left to stand for several tens of minutes. The drain valve is opened, and the upper wastewater is discharged through the drain pipe to the sewage tank for secondary sewage treatment. After the upper wastewater is discharged, the drain valve is closed, and the motor drives the spiral shaft to rotate synchronously, which in turn drives the spiral blades and scraper to rotate synchronously. The scraper hangs the sediment on the inner wall of the conical cylinder into the fine cylinder. The sewage valve is opened, and the sediment at the bottom of the fine cylinder is discharged through the sewage pipe.

[0004] However, the flocculent material formed after mixing and stirring tends to stick to the stirring blades when it settles downwards. Therefore, when discharging wastewater later, the interference from the stirring blades can prevent some of the flocculent material from being discharged and collected. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the wastewater purification device for biological research and development provided by this utility model includes components such as a reaction tank, stirring blades and a quadrangular prism, so that the flocculent material hanging on the surface of the stirring blade can automatically detach from the stirring blade.

Figure 3As shown, each set of stirring blades 4 is evenly distributed from top to bottom. The rotation of the quadrangular prism 5 can cause the stirring blades 4 to move synchronously, thereby realizing the full stirring and mixing of wastewater and flocculant in the reaction tank 1. A rotating shaft 16 is rotatably connected to one side of the socket 9.

An inclined rack 11 is inserted into the surface of the rotating shaft 16, and the inclined rack 11 is meshed with the inclined gear 10. An electric telescopic rod 15 is provided between the inclined rack 11 and the rotating shaft 16. During the stirring process, the extension and retraction of the electric telescopic rod 15 can be used to raise and lower the inclined rack 11.

The swing gear 8 can simultaneously drive the rotating shaft 16 and the inclined rack 11 and inclined gear 10 on its surface to swing up and down. This design can realize the up and down swing of the stirring blade 4.
