The invention discloses a filter device for extractive liquid with high viscosity, which comprises a funnel-shaped outer shell, a filter screen with hard surface material around and at the bottom of the shell, a vertical rod at the bottom center of the filter screen, and a connecting rod with a rotating component; at least one slender strip-shaped scraper is arranged between the shell and the filter screen, and the length of the scraper is arranged. Equal to the distance between the upper edge of the filter screen and the center of the bottom of the filter screen, the scraper matches the surrounding and bottom of the filter screen; the vertical rod passes through the bottom of the filter screen, and the scraper is connected with the vertical rod at one end of the bottom of the filter screen, and the rotating component drives the vertical rod and the scraper to rotate relative to the filter screen. The device can effectively scrape the filtrate adhering to the surface of the filter hole with a slow flow rate through a rotating scraper, which can make the filtrate flow into streams quickly and improve the filtering speed and efficiency. The scraper speed can be accurately controlled by the chip, and the rotational speed can be changed for different viscous liquids.
【技术实现步骤摘要】
一种高粘稠度萃取液过滤装置
本专利技术属于液体过滤设备领域,特别是一种高粘稠度萃取液过滤装置。
技术介绍
目前,在食品药品等领域中,对原料中有效成分的提取往往采用萃取的方式,并在萃取后进行过滤处理,以去除液体中的杂质,使有效成分粘稠度更高。在试验或生产中,漏斗形的容器是最常见的过滤装置,且容器底部设有过滤网等部件,萃取液从上方倒入,经过过滤网完成过滤。现有技术中,例如专利号为“201810088384.5”的专利“一种萃取液过滤装置”,在漏斗内的过滤网的底壁中心可拆卸连接有竖杆,并设有液位传感器和浓度传感器,竖杆可以带动滤网相对于漏斗转动,通过离心力甩掉部分过滤网吸附的杂质,直至完成装置内萃取液的过滤工作。当需要过滤的液体粘稠度很高时,由于液体具有很高的粘滞阻力,同时滤网的滤孔非常小,液体从滤孔滤过后会粘滞在滤孔附近缓慢流动下落,造成滤液从滤网上留下的速率过慢,从而严重影响高粘稠度液体的过滤效率。
