Centrifugal equipment for solid-liquid separation

Abstract

The invention discloses centrifugal equipment for solid-liquid separation. The centrifugal equipment comprises a rack, a centrifuge shell body and a light-liquid discharge pipe, a rotating drum, a rotating shaft, a feeding pipe and a washing pipe, a drainage plate, a suction filter and a speed adjusting motor; and the suction filter comprises vacuum equipment, a liquid outlet pipe, a casing, a filter screen bracket and a nanoscale filter screen. According to the technical scheme, mixed raw liquid can be centrifugally stratified under the high speed rotation of the rotating drum, graphene formsmodified graphene as an amphiphilic nano-material under the centrifugal action, and the modified graphene is washed into a sewage outlet by the washing pipe under the low-speed rotation of the rotating drum and resides on the nano-scale filter screen after removing water and alcohol under the action of the suction filter at the same time; and moreover, the suction filter can greatly improve the flow rate of the water and the alcohol, so that the production efficiency of products is effectively improved.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation equipment, in particular to a centrifugal equipment for solid-liquid separation. Background technique [0002] Amphiphilic graphene is a new type of modified graphene material, which has the characteristics of one side being lipophilic and the other side being hydrophilic, which can promote the detachment of crude oil from the wall of oil mines during oil extraction, greatly improving the difficulty and efficiency of mining. However, amphiphilic graphene needs to be separated from a mixed solution of amphiphilic graphene, kerosene, alcohol, and water, which is difficult. [0003] Refer to the Chinese patent "High-speed centrifuge" with the patent number CN201810239624, which discloses a high-speed centrifuge, including a flat plate with a base, a motor, a centrifuge casing, a transmission bracket, a main shaft, a drum, a washing pipe, and a feeding pipe , the centrifuge shell and ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patents can separate heavy oil and petroleum in a rational way, but for the mixed solution composed of graphene, kerosene, alcohol and water, it is still impossible to achieve separation. The more traditional method is to first carry out solid-liquid separation, the Graphene is centrifuged in a high-speed centrifuge and adhered to the wall. After the equipment is dismantled, the modified graphene material is manually scraped off by a scraper. This method is extremely inconvenient and the production efficiency is very low.
