2results about How to "The method is simple and practical" patented technology

This patent relates to a double-layer hollow metal plate and its combined structure, particularly to a double-layer hollow metal plate with inwardly welded openings and its combined structure, comprising a proximal metal plate (1), multiple inwardly welded components (2), and a distal metal plate (3). The distance between the proximal metal plate (1) and the distal metal plate (3) is greater than 20 mm and less than 150 mm. The proximal metal plate (1) has multiple through holes (11). One end of each inwardly welded component (2) passes through a through hole (11) and is welded to the distal metal plate (3). The inwardly welded component (2) is also welded to the proximal metal plate (1). This patent transforms the disadvantages of small cavities into advantages. The method used is simple and practical. By opening holes in the proximal metal plate as positioning points for the connectors, the difficulty of matching or precisely fitting multiple connectors is reduced. The cost is low and the practicality is high.

The invention discloses a screening method of an ardealite flotation collecting agent, which comprises the following steps: providing a molecular structure of the collecting agent, and obtaining components of impurities in ardealite; respectively constructing a molecular model of the collecting agent and a unit cell model of the impurities, and carrying out geometric optimization to obtain an optimized molecular model of the collecting agent and an optimized unit cell model of the impurities; constructing a unit cell box of the impurities; on the basis of the optimized collecting agent molecular model and the impurity unit cell box, an adsorption model between the collecting agent and the impurities is built; performing molecular dynamics simulation calculation on the adsorption model to obtain adsorption energy between the collecting agent and the impurities; and sorting is conducted according to the size of the adsorption energy, and the collecting agent with the good collecting effect is screened out.
