Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine, and particularly to a filtering device and method for traditional Chinese medicine residues in traditional Chinese medicine production. Background Art

[0002] Traditional Chinese medicine is a medicine that is guided by traditional Chinese medicine theory for collection, processing, preparation, explaining the mechanism of action, and guiding clinical application. Traditional Chinese medicine mainly comes from natural medicines and their processed products, including plant medicines, animal medicines, mineral medicines, and some chemical and biological product medicines. Since traditional Chinese medicine mainly consists of plant medicines, there is a saying that "all medicines are based on herbs". When traditional Chinese medicine is processed, traditional Chinese medicine residues will be generated, and filtration is required when removing the traditional Chinese medicine residues.

The filtering tank is fixed on the bracket. At least two sliding grooves are oppositely arranged on the inner wall of the filtering tank, and the sliding grooves are vertically arranged. Both the extrusion plate and the filtering plate are provided with sliders that are slidably matched with the sliding grooves. The extrusion plate is located above the filtering plate. The cover body covers the feeding port of the filtering tank. A limiting groove for preventing the cover body from rotating is vertically arranged on the cover body. A limiting slider that is matched with the limiting groove is arranged at the upper end of the filtering tank. The extrusion bolt is threadedly connected to the cover body.
