5results 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 liquid fertilizer fine quantitative proportioning alternate irrigation and fertilization equipment and a use method thereof, and belongs to the technical field of fertilization equipment. The invention discloses liquid fertilizer refined quantitative proportioning alternate irrigation and fertilization equipment which comprises a rack, a control panel and a soil nutrient detection instrument electrically connected with the control panel are arranged on the rack, and the equipment further comprises a walking assembly fixedly arranged on the lower side of the rack and used for driving the rack to walk; the support is fixedly arranged on the upper side of the rack, charging barrels of the same structure are arranged on the support, one charging barrel is used for storing irrigation water, and the other charging barrel is used for storing liquid fertilizer; a mixing mechanism; when the walking assembly drives the machine frame to conduct fertilization and irrigation along crops, quantitative and small amount of irrigation water and liquid fertilizer are mixed in proportion, the diluted liquid fertilizer is suitable for fertilization work of soil with different nutrients, the mixing time is short, mixing is uniform, and the fertilization and irrigation effect and the fertilization and irrigation efficiency are guaranteed.

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.
