The invention relates to a lithium ion battery silicon-based negative material and a preparation method thereof, which belong to the technical field of lithium ion battery negative materials. The lithium ion battery silicon-based negative material is prepared from silicon monoxide; the macroscopic particle diameter of the negative material is 10-25 micrometers; according to a microstructure, the negative material is composed of nanometer silicon particles covered with silica; the internal silicon particle diameter of the negative material is 20-30 nanometers; and at 0.1C discharge rate, the first discharge capacity of the negative material reaches 2010-2640 mAh / g, and is 420-790 mAh / g after 50 cycles. The negative materials with the structure characteristic combines the dispersion and the reduction of silicon particles; and on one hand, the silicon particles can be dispersed by a pore channel structure of silica so as to provide a space for the expansion of silicon in charge and discharge processes, on the other hand, the particle diameter of silicon can be reduced, and therefore, a volume effect of silicon in the charge and discharge processes can be weakened.

The invention provides a filter device for high-concentration herb residues and / or fruit residues. The device comprises a feeding component, a filter screen cartridge (2), a connecting shaft (6), a liquid receiving component (3), a power component (4), a transmission component (5) and a stand column (8). Under the rotation of the filter screen cartridge (2), herb residues and / or fruit residues, which are extracted by a solvent, are gathered into clusters in the screen cartridge and roll along with the rotation of the screen cartridge; herb residue clusters and / or fruit residue clusters form cracks in the rolling process and then are clustered again. The filter device has an effect of promoting the seepage of liquid in the herb residues and / or fruit residues, therefore an extracting solution or original juice are fully removed, and the solid-liquid separation effect is realized. The filter device is suitable for the berry or fruit kind of fruit residue treatment and is also suitable for filtering the extracted residues of other plants such as maca, kelp, abelmoschus esculentus, abelmoschus manihot, cistanche and cynomorium songaricum.
