In the current context of rising global oil prices and energy crisis, how to find a plant that can convert and make biodiesel or gasoline has become a social focus. Right now, in the 50-mu experimental site in the Xuanmen second phase reclamation area, Yuhuan Greenfield Technology Co., Ltd. has successfully introduced an energy plant called “Jerusalem†through the Chinese Academy of Sciences for transformation and biodiesel or gasoline production.
Jerusalem artichoke, the common name of Jerusalem artichoke, ground ring, ginger is not spicy, resistant to barren, drought, cold, planting advice, extensive management, for a one-time sowing many harvested crops. Jerusalem artichoke tubers edible, but also through deep processing into starch, inulin, alcohol, health products and other important products. Of course, it is more valuable for development and use because it can be used as raw material for biodiesel or gasoline. “Now the Chinese Academy of Sciences has always recognized that Jerusalem artichoke is the best raw material for bio-energy extraction. First, its ethanol content is relatively high. The second one will not compete with the food crops that humans eat, so it is recognized by the Chinese Academy of Sciences for a period of time. As a substitute for bio-energy extraction, said Wang Enfeng, Yuhuan Greenfield Technology Co., Ltd.
According to reports, the scientists of the Chinese Academy of Sciences have been engaged in the research of Jerusalem artichoke for many years and have already achieved results in order to find ways to replace the plant that can replace corn and convert it into biodiesel or gasoline to solve the problem of large amounts of farmland being occupied. It is a series of polyfructose-inulin extracted from tubers of Jerusalem artichoke. After a complicated chemical process, it can be converted into fructooligosaccharides. The high fructooligosaccharides contained in fructooligosaccharides are added to E. coli and then acted as cell factories. Can be converted to biodiesel.
"The benefits of Jerusalem artichoke are very good. We can now achieve a maximum output of 150,000 kilograms per mu. If the minimum price is calculated in terms of two cents, there are also 30,000 yuan in benefits, so this thing is very impressive and worth promoting." said Wang Enfeng At present, the core of scientists' work lies in finding more economical, convenient, and simple conversion processes and methods, so as to minimize the cost, ultimately realize commercialization and industrialization, and allow motor vehicles to truly bid farewell to natural diesel or gasoline. Humans are free from the threat of energy crisis. It is because of such a great function that the planting benefits of Jerusalem artichoke are naturally good.
Plate rolling is a process of continuous three-point bending of sheet metal using a plate rolling machine. The equipment puts the sheet material between the upper and lower work rolls when rolling. The upper roller is raised and lowered vertically, and the two lower rollers rotate and move horizontally relative to the axis of the upper roller. When the upper roll descends, the plate is plastically deformed and bent between the upper and lower work rolls. The continuous rotation of the bottom roller drives the steel plate to advance and retreat through the friction between the plate and the roller to complete the coiling.
1. Pre-bending. When the plate is rolled, there is a length at both ends of the plate that does not bend because it does not touch the upper roller. It is called the remaining straight edge. In the process, the minimum force arm at which the plate starts to bend is called the theoretical remaining straight edge. The bending form (symmetrical bending, asymmetrical bending) is related.
2. Centering. The purpose of centering is to make the generatrix of the workpiece parallel to the roller axis to prevent skew.
3. Roll round. Rolling is the main process of product forming, which is divided into two types: one-time feed and multiple feeds. Multiple feeds are commonly used for rolling thick plates. The number of feeds depends on the technological constraints (such as the maximum allowable deformation during cold rolling) and equipment constraints (such as non-slip conditions and power conditions). When the rebound of the cold coil is significant, a certain amount of overcoiling must be added.
4. Straightening round. The purpose of rounding is to make the curvature of the entire circle as uniform as possible to ensure product quality. The general rounding process is divided into three steps:
(1) Load: According to experience or calculation, adjust the work roll to the position of the required maximum correction curvature.
(2) Rounding: Roll the roller 1 to 2 turns under the corrected curvature to make the entire curling rate uniform.
(3) Unloading: gradually unload the load, so that the workpiece is rolled several times under the gradually reduced correction load.
