3results about How to "Short mixing time" patented technology

This invention relates to the field of wastewater treatment technology, and more particularly to a wastewater treatment device based on an algae-bacteria symbiotic photobioreactor, comprising: a mounting frame and a treatment tank fixed inside the mounting frame. The treatment tank contains a reaction assembly, which includes a drive rod and a reaction spiral blade. The drive rod is vertically positioned inside the treatment tank, and the reaction spiral blade is fitted onto the drive rod. The reaction spiral blade has reaction holes and contains a biological reaction layer. A collection hood, shaped like an inverted frustum, is located at the bottom of the treatment tank. Two symmetrical outlets are located at the bottom of the collection hood. A collection assembly, comprising a sealing ring, a guide ring, a movable rod, and a collection box, is located below the collection hood. The sealing ring is fixedly connected to the bottom side of the collection hood. This invention causes the generated sediment to converge centripetally at the bottom of the treatment tank, avoiding the formation of eddy current dead zones.

The invention discloses a metal powder mixing device, and relates to the technical field of metal powder mixing, the metal powder mixing device comprises a mechanism cylinder, a plurality of annularly distributed storage cavities are formed in the edge of the upper side of the mechanism cylinder, auger conveying mechanisms are arranged on the inner sides of the storage cavities, a mixing mechanism is arranged on the inner side of the mechanism cylinder, and the mixing mechanism is arranged on the inner side of the mechanism cylinder. A heat dissipation mechanism is arranged on the lower side of the mechanism cylinder, the material mixing mechanism comprises a spreading assembly and a first stirring frame which are distributed up and down, the spreading assembly and the first stirring frame are located on the inner side of the mechanism cylinder, the bottom wall of the mechanism cylinder is conical, and a first airflow mixing mechanism is arranged on the bottom wall of the mechanism cylinder. According to the metal powder mixing device, through the arrangement of the spreading assembly, the mixing speed of metal powder is increased in a small-batch, pneumatic mixing and physical stirring mode, the problem of long mixing time is avoided, and the problems of high-strength mixing of easily-broken powder and deformed particles through mechanical stirring are also avoided.

The utility model discloses a nano material stirring device for a composite board, and relates to the technical field of nano material processing. The stirring device comprises two leg frames, the opposite sides of the two leg frames are fixedly connected with a stirring barrel, the back face of the stirring barrel is fixedly connected with a feeding port, a stirring assembly is arranged above the stirring barrel and comprises a protective shell, and the left side and the right side of the protective shell are both fixedly connected with installation blocks. The stirring assembly is arranged, specifically, a rotating shaft drives a top bevel gear to rotate, the top bevel gear drives a middle bevel gear to rotate, the middle bevel gear drives a bottom bevel gear to rotate, the bottom bevel gear drives a lantern ring to rotate, and the lantern ring drives a plurality of outer stirring rings to rotate; and meanwhile, the rotating shaft drives the plurality of inner stirring rings to rotate to form bidirectional stirring, so that compared with a traditional stirring device, the required stirring time is shorter, and not only is the stirring uniformity improved, but also the production efficiency is improved.
