Description

Technical Field

[0001] This utility model relates to the field of veterinary drug production extraction technology, and more specifically, to a veterinary drug production liquid extraction device. Background Technology

[0002] Veterinary drug solutions refer to liquid veterinary drugs made from Chinese medicinal herbs, chemical raw materials, or bioactive substances through processes such as extraction, purification, and formulation. They are used for oral, injection, or external administration. Veterinary drug solution extraction is a key technology for extracting effective components from raw materials such as animals and plants and making them into drug solutions. It generally adopts high-temperature extraction. The specific steps are to mix the raw materials of medicinal materials with solvents and dissolve the effective components in the medicinal materials by heating and stirring the solvent.

[0003] However, in the existing veterinary drug extraction process, the solvent and medicinal materials are mixed by stirring alone, resulting in a low dissolution efficiency of the effective components in the medicinal materials. Furthermore, after the extraction of the medicinal materials is completed, a portion of the extract is retained in the residue, making it impossible to fully filter and collect the extract containing the effective components of the medicinal materials.

Furthermore, after the extraction of the medicinal materials is completed, a portion of the extract is absorbed and retained in the residue, making it impossible to fully filter and collect the extract containing the effective components of the medicinal materials.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention utilizes a lifting and rotating mechanism to drive the second filter screen to move up and down reciprocally, compressing and expanding the movable space of the medicinal materials. During the compression process, the stirring shaft drives the grinding roller to rotate synchronously, and together with the first and second filter screens, the accumulated medicinal materials are ground, which helps to break down the medicinal material cells, expose the effective components to the solvent, and fully extract the effective components from the medicinal materials. During the expansion process, the grinding roller fully stirs the medicinal materials, allowing the medicinal materials to fully contact the solvent and improve the extraction efficiency. Similarly, when filtering the extract, the residue is further ground, which helps to fully squeeze out the extract and filter and collect it.

[0012] This invention uses a drive motor to drive a threaded rod to rotate. The threaded rod, through its threaded transmission, can lift or lower the lid. The T-shaped slide bar acts as a limiter. Before and after extraction, the lid can be automatically lifted to remove the second filter from the extraction tank, facilitating the addition of medicinal materials or the removal of dregs.
