Solid and liquid separator capable of controlling liquid extracting amount conveniently for chemical teaching experiment

Abstract

The invention discloses a solid and liquid separator capable of controlling the liquid extracting amount conveniently for a chemical teaching experiment. The separator comprises a supporting base anda worm. The left and right sides of the upper portion of the supporting base are each provided with a lower supporting rod, a lower fixing pipe is arranged above the lower supporting rods, an upper fixing pipe is arranged above the lower fixing pipe, an upper supporting rod is installed above the upper fixing pipe, the inner sides of the upper fixing pipe and the lower fixing pipe are each fixedlyprovided with an installing frame, and the outer sides of the upper fixing pipe and the lower fixing pipe are each provided with a fastening bolt. The solid and liquid separator capable of controlling the liquid extracting amount conveniently for the chemical teaching experiment is provided with a first placement shell and a second placement shell, the peripheries and the bottoms of the first placement shell and the second placement shell are each provided with a mesh-shaped structure, solid-liquid mixtures can be filtered at the same time at different heights, liquid at different positions flows out through the first placement shell and the second placement shell, the filter efficiency is improved, and the filter time is shortened.

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...
