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.

The utility model discloses a carton crushing and compressing device, which relates to the technical field of carton crushing and processing equipment, and comprises a base and a crushing box, the bottom of the crushing box is fixedly connected with a plurality of supporting legs, the bottoms of the supporting legs are fixedly connected with the top of the base, and the top of the crushing box is provided with a feed hopper. A discharging groove is formed in the position, close to the bottom, of one side of the smashing box, double smashing mechanisms are fixedly installed inside, outside and at the bottom of the smashing box, a compression box is fixedly installed at the top of the base, the top of the compression box is designed to be open, the compression box is located below the discharging groove, and a compression mechanism is fixedly installed on one side of the outer portion of the smashing box. The compression mechanism is located over the compression box. The paper box crushing and compressing device can effectively solve the problems that in the prior art, the continuity of crushing and compressing processing of paper boxes is poor, and consequently the overall working efficiency of crushing and compressing of the paper boxes is low.

The invention discloses a pretreatment device for vegetable pesticide residue detection. The pretreatment device comprises a treatment table, a treatment pipeline, a movable plate, a rolling gear, a first rotating shaft, a second rotating shaft, a sleeve, a sleeve rod and a matching wheel, the two grinding gears which do circular motion are matched with the sleeve rod, so that the crushed vegetables are stacked; the matching assembly is used for enabling the matching wheel to tightly abut against the rolling gear; the detected vegetables are put into the processing pipeline, the vegetables enter the rolling gears, the motor drives the first rotating shaft to rotate in the original position, one corresponding rolling gear rotates, the other rolling gear rotates, the first rotating shaft rotates, the first rotating shaft rotates, the first rotating shaft rotates, the second rotating shaft rotates, and the adsorption assembly is used for conveying the vegetables located at the bottom of the processing pipeline again to the position above the meshing position of the two rolling gears. The two rolling gears are meshed all the time, so that the two rolling gears rotate, the first rotating shaft and the second rotating shaft are located on the edges of the two rolling gears respectively, the two rolling gears rotate while doing circular motion, and the vegetable crushing efficiency is improved.

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.
