The invention discloses a high-water-content lignite moisture accurate regulation and control method and device, and relates to the technical field of lignite treatment device.The high-water-content lignite moisture accurate regulation and control device comprises a rack and further comprises a crushing mechanism connected to the rack, and the input end of the crushing mechanism communicates with a feeding port; the input end of the vacuum dehydration system is communicated with the output end of the crushing mechanism; the input end of the feeding mechanism is communicated with the output end of the vacuum dehydration system; and the input end of the upgrading mechanism communicates with the output end of the feeding mechanism. High-water-content lignite is crushed through the crushing mechanism, water and pulverized coal are separated and collected through the vacuum dehydration system, and ash which affects heat production and pollutes the environment in the pulverized coal is removed through the quality improving mechanism, so that the combustion quality of the lignite powder is improved, and emission of pollutants is reduced; and conveying of the pulverized coal and adding of the corresponding water content are continuously performed through the scraper conveying belt, so that the influence of water and ash in the lignite with the high water content is reduced, and the water in the lignite is accurately regulated and controlled.

This utility model relates to the field of crushing equipment and discloses a high-efficiency straw crushing device, including a crushing box. The top of the crushing box has a feed hole, and a feed hopper is installed inside the crushing box. Two crushing rollers for straw crushing are rotatably installed inside the crushing box, and a discharge hole is opened on one inner wall of the crushing box. A conveying shell for feeding straw is fixedly installed on the top of the crushing box. A conveying mechanism for conveying straw is provided inside the conveying shell, and a discharge hole is opened on the bottom inner wall of the conveying shell, located directly above the feed hole. A housing is fixedly installed on the top of the conveying shell, and a lifting seat is slidably installed inside the housing. This utility model has the following advantages and effects: it achieves efficient straw feeding through the conveying mechanism, continuously cuts the straw using a cutting blade, and efficiently crushes the straw with the help of the crushing rollers, significantly improving the straw processing efficiency and effect.
