Technical Field

The invention relates to an extraction device, in particular to equipment and an extraction method capable of performing dust-free extraction on medicinal materials of traditional Chinese veterinary medicines.

Background

Veterinary drugs are emerging industries in recent years. In brief, the theory of traditional Chinese medicine is applied to animals. Veterinary drug residues have become an important obstacle affecting the development of animal husbandry. Experts have considered that veterinary drugs will gradually replace chemicals to a great extent because they do not pose a threat to food safety.

For planting and collecting some Chinese medicinal materials, extraction of effective components is one of key links. Extracting the effective components of the effective monomers, and further separating and purifying the effective components to obtain the effective monomers is an important content in the research field of traditional Chinese medicines. A common device for extracting medicinal materials is an extraction tank, in which medicinal materials and a solvent are generally placed in the tank, and an extraction solution of the medicinal materials can be obtained by different methods such as soaking, heating, stirring, standing and the like.

However, in the actual operation process, environmental pollution is often generated in the process of filling the medicinal materials into the extraction tank, and particularly for some medicinal materials in the states of dust and powder, the emitted medicinal materials can affect the workshop environment and the physical health of operators, and can also affect the normal production of other processes. In addition, in the process of discharging the medicinal material extracting solution, due to overhigh temperature or sputtering, the liquid below the extracting tank easily has serious influence on the surrounding environment, and personnel in the surrounding environment are more harmed to health.
