This utility model discloses a nozzle device for a centrifuge containing blast furnace molten slag, including a centrifuge roller, a rubber ring, multiple nozzles, and an air ring. The rubber ring is configured to be extended to cover the cotton-like area under the centrifuge roller. An adjustable nozzle angle mechanism is provided between the rubber ring and the air ring. This mechanism includes multiple adjustable supports, one end of which is fixed to the rubber ring, and the other end is connected to the nozzle. This utility model, by extending the rubber ring, increasing the number of nozzles to at least 12, and combining the adjustable nozzle angle mechanism with an anti-clogging device, clears the blind spots of glue coverage in the cotton-like area under the centrifuge roller, reducing the waste cotton rate. Simultaneously, combined with the air ring groove interlocking structure and auxiliary air duct system, it improves the uniformity of cotton dispersion, reduces nozzle maintenance frequency, increases daily output per line, saves glue costs and waste disposal fees, improves the stability of continuous production line operation and resource utilization efficiency, and meets the requirements of efficient utilization and high-cleanliness production of blast furnace molten slag in the metallurgical industry.

The invention relates to the field of microorganisms, and discloses recombinant escherichia coli, a construction method and application thereof and a method for producing L-leucine. The recombinant escherichia coli simultaneously contains a coding gene of an overexpressed pyruvic acid transport protein, a coding gene of an overexpressed glucose transport protein and a coding gene of an overexpressed 6-phosphofructokinase, and does not contain a coding gene of fructose-1, 6-diphosphatase. The recombinant Escherichia coli provided by the invention can significantly improve the utilization rate of the raw material glucose, improve the yield of L-leucine and inhibit the generation of byproducts. In a preferred embodiment of the invention, when the recombinant escherichia coli is fermented for 20 hours in a 5L fermentation tank, the yield of L-leucine reaches 70 g / L, the saccharic acid conversion rate reaches 36%, the daily yield is remarkably increased, and the production cost is greatly saved.

This utility model belongs to the field of wood processing technology, specifically disclosing a high-efficiency adhesive dispensing and splicing system. It includes an adhesive dispensing mechanism for applying adhesive to wood veneers. A first conveying device is located at the front of the dispensing mechanism for conveying the (N+1)th veneer, with the feeding direction from front to back. A first cutting device for aligning the ends of the veneers is located at the rear of the dispensing mechanism. A second conveying device is located at the rear of the dispensing mechanism for conveying the Nth veneer. A second cutting device for aligning the ends of the veneers is located at the rear of the dispensing mechanism. The second cutting device can precisely align the ends of the veneers to ensure the veneer length meets splicing requirements, improving the accuracy and quality of splicing. A cold pressing device is located at the front of the dispensing mechanism for pressing and splicing the (N+1)th and Nth veneers. Its pressing process is stable and reliable, effectively reducing splicing defects. Its special arrangement reduces bonding waiting time and improves splicing efficiency.

This invention relates to a method for improving the crystal quality of large-size thick-film silicon epitaxial wafers. By comprehensively designing parameters such as the radial temperature gradient difference of the silicon substrate placement area, the silicon epitaxial layer growth temperature, the evacuation time before silicon epitaxial layer growth, the silicon epitaxial layer growth rate, the flatness of the graphite substrate, and the rotation speed of the graphite substrate during silicon epitaxial layer growth, the crystal quality of large-size thick-film silicon epitaxial wafers is improved with simple process and batch reproducibility. It avoids problems such as edge chipping, cracking, and fragmentation of silicon epitaxial wafers. It can be applied to the industrial mass production of large-size thick-film silicon epitaxial wafers with diameters of 150~200mm and silicon epitaxial layer thicknesses greater than 100μm.

This invention discloses a dynamic decision-based longwall fully mechanized coal mining technology using two mining machines, belonging to the field of coal mine monitoring and control technology. The technology includes: a first mining machine and a second mining machine simultaneously starting coal mining from both ends of the working face; at the start of mining, the central control system determines an initial convergence point based on first and second initial state data; during mining, a first sensor and a second sensor collect first and second motion state data in real time, and the central control system determines a dynamic convergence point based on these data; the central control system adjusts the working states of the first and second mining machines in real time based on changes in the dynamic convergence point. This invention provides a dynamic decision-based longwall fully mechanized coal mining technology using two mining machines, generating a dynamic convergence point through dynamic real-time decision-making, thereby minimizing waiting time and achieving seamless coordination.
