4results about How to "Solving Segregation Problems" patented technology

The invention relates to asphalt stirring equipment, and relates to the field of asphalt stirring processing devices. The device comprises a supporting piece, a stirring piece, a preheating piece and a mixing piece, the supporting piece comprises a supporting frame, a first rotating frame and a second rotating frame, the first rotating frame and the second rotating frame are symmetrically arranged above the supporting frame, the stirring piece comprises a stirring barrel, and the stirring barrel is horizontally arranged above the supporting frame; and the stirring barrel is horizontally and rotatably connected into the first rotating frame and the second rotating frame, the feeding end of the stirring barrel communicates with and is fixedly provided with a preheating part, and the preheating part is used for preheating the asphalt material. Through the distributed arrangement and reverse rotation design of the stirring ring pieces, the stirring strength is uniformly distributed in the radial direction, the linear speed of the stirring ring pieces and the linear speed of the annular stirring racks form difference value complementation, the shearing force deviation of materials at any radial position is achieved, the asphalt emulsification phenomenon is effectively avoided, and the pavement problem caused by uneven mixing is solved.

This invention discloses a stepped mixing device and process for highly homogenized and anti-segregation dry mortar, belonging to the field of dry mortar production technology. The device includes a shell with feet at the bottom. Inside the shell, from top to bottom, a primary mixing component, a suction component, and a secondary mixing component are sequentially connected, forming a three-stage stepped mixing structure. A rotating component driving the secondary mixing component is located on the outside of the shell. This invention effectively solves the segregation problem caused by density and particle size differences in multi-component materials in dry mortar through three-stage stepped mixing of "pre-dispersion, pneumatic homogenization, and deep shearing," significantly improving mortar homogeneity and batch stability, shortening mixing time, and increasing production efficiency. It is suitable for the large-scale production of various types of dry mortar.

The application discloses a synergistically enhanced potassium-magnesium sulfate type compound fertilizer and a preparation method thereof, and belongs to the technical field of potassium-magnesium sulfate type compound fertilizers. The synergistically enhanced potassium-magnesium sulfate type compound fertilizer is composed of the following components in parts by weight: 200-250 parts of potassium-magnesium sulfate, 600-700 parts of powdered potassium sulfate, 40-60 parts of ammonium polyphosphate modified magnesium oxide, 10-20 parts of potassium fulvate, and 80-120 parts of a magnesium chloride-citric acid compound solution. The ammonium polyphosphate modified magnesium oxide is introduced, the unique polyphosphate long-chain structure of the ammonium polyphosphate is used as an ion lock, magnesium ions are captured and chelated in situ at a fertilizer dissolving micro-interface, and a complex with strong anti-interference capability is formed; the magnesium in this form can effectively avoid the competitive inhibition of high-concentration potassium ions on root absorption channels.
