Product Description
Leaching refers to the process of extracting a soluble substance from a solid with a chemical solvent, also known as leaching.The chemical solvent used for leaching is called leaching agent.The solution obtained after leaching is called the leaching solution, and the remaining solids are called residue.The leaching effect is expressed as the leaching rate, that is, the percentage of the soluble substance in the solid dissolved into the leaching solution.The solids leached in hydrometallurgy are intermediate metallurgical products such as ore, concentrate, calcine or copper matte, smoke dust and anode mud.The commonly used industrial leaching agents are water, acid, alkali and brine solutions.The leaching of low grade raw materials consumes a large amount of solvent and the leaching agent must be cheap and economical to regenerate.
The extractor is the core equipment of the oil leaching process, and its quality is directly related to the economic and technical indexes of the leaching production.Therefore, the reasonable selection of leaching extractor is of great significance to improve the efficiency of leaching production, reduce production cost and improve the economic benefit of the leaching oil plant.
Commonly used extractors
1. Tank group type extractor
The extractor is a cylindrical vessel with a saucer head.There is a false bottom in the bottom of the cylindrical tank body, which is composed of two layers of sieve diameter of 8mm sieve plate, sandwiced with sacks or brown fiber and so on.The false bottom is mounted on a lower lattice iron frame to support the weight of a tank of billets and the leaching solvent, as well as the steam pressure during the "down" operation (generally around 98kPa).After the false bottom is installed, it can only be mixed with liquid such as oil and solvent, and solid particles such as meal can not be passed.The feed pipe is provided on the top cover, the pulp outlet is provided on the tank body, and the shell is provided with a variety of related operations.
The characteristics of tank group leaching are simple equipment, less investment, small consumption of solvent and energy, strong adaptability of oil, suitable for small production enterprises with many varieties and small batches.
2. Flat turn extractor
Domestic oil processing plant, the use of continuous leacher was main activities turn flat leacher, whe s ring drag chain leacher gradually step by experimental people use phase, activity and flat bottom flat spin leacher because of its simple structure, easy manufacturing, low power consumption, spraying and soaking, leaching effect is good, the combination of mixing machine oil filter through internal tent after less powder and the characteristics of the mixed oil concentration is high, and widely make leacher also gradually moved from the activity at the end of development by the end of fixed shape.
3. Box chain extractor
Box chain type leach in the push box structure, the use of a similar box format and transfer leach box design, so that the material on the bed is divided into several independent units;The soaking area is formed in each material grid to obtain better soaking effect.Moreover, it can effectively prevent the mixed oil at all levels from streaming on the material layer and ensure the concentration gradient between each section of spraying.In the moving parts, the use of similar ring and drag chain type extractor movement principle, the use of dual-axis hydraulic motor drive, balanced force, reliable operation, less maintenance costs, while the speed of the hydraulic motor can be adjusted freely, so as to adapt to a variety of different oil.In the structure of the box, the split design of the annular extractor is adopted, which greatly facilitates transportation and installation, and can better meet the needs of large-scale modern factories.
The whole box chain type leach is composed of a box body, a pushing box part, a driving mechanism, a box-type grid, a mixing oil circulation and a spraying section, and a feeding choke, etc.
