3results about How to "Increase unit capacity" patented technology

The application provides a pickling unit automatic speed control method and system based on multi-factor constraints, and relates to the technical field of cold-rolled strip steel production. In view of the defects that the existing control relies on manual operation or primary automation and is difficult to cope with multiple constraints and instantaneous working conditions, the method comprises the following steps: constructing a multi-factor constraint model covering process, equipment, logistics, acid liquid and instantaneous working conditions; collecting corresponding data in real time; dynamically calculating a global optimal speed setting value through multi-layer decision logic, calculating a basic speed first and then superimposing an instantaneous working condition constraint, and directly triggering emergency disposal through high-priority alarm; issuing an instruction for execution and closed-loop feedback, and combining machine learning for self-learning optimization. The application realizes automatic intelligent control of the unit speed, guarantees quality and equipment safety, improves production efficiency and continuity, and reduces energy consumption cost.

This invention discloses a hot melt adhesive for high-temperature protective clothing and its preparation method, comprising the following raw materials: Fischer-Tropsch wax, styrene-isoprene-styrene block copolymer with 0% diblock content, styrene-isoprene-styrene block copolymer with 20-30% diblock content, styrene-isoprene-styrene block copolymer with 40-50% diblock content, rosin resin, petroleum resin, ethylene-vinyl acetate copolymer, and antioxidant. This hot melt adhesive requires no toxic solvents, possesses both heat resistance and water resistance, and is suitable for high-temperature protective clothing. The preparation method of this hot melt adhesive involves heating and mixing polymer materials without adding any solvents or toxic substances during the preparation process, reducing the risk of toluene poisoning, completely solving the problems of solvent evaporation and recovery, and, more importantly, eliminating safety hazards in the storage and use of organic chemicals, achieving environmentally friendly, safe, and efficient production.

The utility model relates to the technical field of fermented bean curd, specifically relates to a multilayer fermented bean curd fermentation frame, including multigroup vertical interval arrangement's through -and -through tray, the inside lower side wall fixed limit strip for supporting embedded hole -like board of tray, the both sides of hole -like board are equipped with pull rope and is convenient for to extract, the rotating plate of rotating groove is fixed in the middle of tray one end, the rotating bearing installed in the groove is arranged on the outside of support column and forms the rotating pivot, need to operate when horizontally pulling tray, rotating bearing rotates along the support column and makes the layer to slide outward, through pull rope to take out hole -like board and its carried bean curd blank, complete detection or replacement operation in open space, after reset, hole -like board returns to limit strip fixed, multilayer tray keeps vertical ventilation state, the structure will traditional longitudinal operation change into horizontal operation, eliminate the need of interlayer reserved arm operating space, make interlayer distance need only satisfy the thickness of bean curd blank and bearing structure, significantly improve the stacking density and capacity in the same space.
