Abstract
Description
技术领域 technical field
本发明涉及一种液体分离装置,具体涉及一种实验室用的过滤装置。 The invention relates to a liquid separation device, in particular to a laboratory filter device.
背景技术 Background technique
漏斗过滤法广泛应用于化学分析领域,在许多化学分析项目中是必经的步骤。传统的漏斗过滤法是将圆形滤纸对折成漏斗状后放入玻璃漏斗中进行过滤,通过玻璃棒向漏斗状的滤纸内注入待过滤的液体,依靠液体本身的重力作为动力进行渗透过滤。 The funnel filtration method is widely used in the field of chemical analysis and is a necessary step in many chemical analysis projects. The traditional funnel filtration method is to fold the circular filter paper into a funnel shape and then put it into a glass funnel for filtration, inject the liquid to be filtered into the funnel-shaped filter paper through a glass rod, and rely on the gravity of the liquid itself as the driving force for permeation filtration.
上述漏斗过滤法存在如下缺点:1)有效过滤面积只占过滤纸的一小部分,滤纸利用率低,过滤效率低下;2)漏斗状滤纸内的液体越来越少时,动力随即减小,过滤速度会越来越慢;3)当采用负压加速过滤时,纸状漏斗顶端容易因受力过度而渗穿;4)由于采用折成漏斗状的滤纸过滤,其过滤容积受滤纸尺寸的限制,一般不能一次性倾倒全部的待过滤液体。 The above-mentioned funnel filtration method has the following disadvantages: 1) The effective filtration area only accounts for a small part of the filter paper, the utilization rate of the filter paper is low, and the filtration efficiency is low; 2) When the liquid in the funnel-shaped filter paper decreases, the power decreases immediately, The filtration speed will become slower and slower; 3) When negative pressure is used to accelerate the filtration, the top of the paper funnel is easy to penetrate due to excessive force; 4) Since the filter paper folded into a funnel shape is used for filtration, its filtration volume is limited by the size of the filter paper Generally, it is not possible to dump all the liquid to be filtered at one time.
