A Solid-Liquid Separator for Chemistry Teaching Experiments Convenient for Controlling Liquid Extraction

Abstract

The invention discloses a solid-liquid separator for chemical teaching experiments which is convenient for controlling the amount of liquid extraction. There is a lower fixed pipe, an upper fixed pipe is arranged above the lower fixed pipe, and an upper support rod is installed above the upper fixed pipe, and an installation frame is fixed on the inner side of the upper fixed pipe and the lower fixed pipe, and the upper fixed pipe The outer sides of the pipe and the lower fixed pipe are all equipped with fastening bolts. The solid-liquid separator for chemical teaching experiments that is convenient for controlling the amount of liquid extraction is provided with a first housing and a second housing, and the surroundings and bottoms of the first housing and the second housing are mesh-like structures , thereby facilitating the simultaneous filtration of the solid-liquid mixture at different heights, so that the liquids at different positions flow out through the first placement housing and the second placement housing, thereby improving filtration efficiency and saving filtration time.

Description

technical field [0001] The invention relates to the technical field of education and teaching, in particular to a solid-liquid separator for chemical teaching experiments which is convenient for controlling the amount of liquid extraction. Background technique [0002] Education and teaching refers to the general term for a series of activities that teach knowledge and skills in various fields. Education and teaching include the teaching of mathematics, Chinese, English, chemistry, biology and other subjects that are common in our lives. In learning chemistry, we generally need to pass experiments. Conduct teaching so that students can better understand the theoretical knowledge in books through experiments. Our most common chemical experiments are solid-liquid separation experiments, which are usually separated by filtration or precipitation. Our most commonly used method is filtration. Although there are various types of solid-liquid separators on the market, there are sti...
