Filtration experimental apparatus for chemical experiment

Abstract

The invention discloses a filtration experimental apparatus for a chemical experiment. The filtration experimental apparatus comprises a bottom plate and an experimental apparatus, wherein the experimental apparatus comprises a lifting device, a supporting rod, a connecting plate, a fixing ring, an adjusting device, a funnel, a beaker, a fixing seat, a limiting device and a sliding device, wherein the bottom of the lifting device is vertically fixed on the top of one end of the bottom plate; the supporting rod is arranged at one side of the lifting device; the connecting plate is fixed at one end, which is far away from the lifting device, of the supporting rod; a through hole is formed in the connecting plate; a threaded hole matched with the connecting plate is formed in the fixing ring; the fixing ring is fixedly connected with the connecting plate through a screw; the adjusting device is fixed on an inner ring of the fixing ring; and the funnel is arranged on the inner side of the fixing ring. According to the filtration experimental apparatus for the chemical experiment disclosed by the invention, the limiting device is fixed at the inner side of the fixing seat, and due to the limiting device, beakers of different sizes can be conveniently fixed, so that the application range is widened.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a filtering experimental device for chemical experiments. Background technique [0002] Chemistry is a natural science that studies the nature, composition, structure, change, use, preparation method and law of changes of substances. Chemistry is closely related to industry, agriculture, daily life, medicine, materials, etc. [0003] The filter device is often used in the teaching of chemistry, and the existing filter is filtered through the funnel, and the fixed position of the funnel is adjusted manually, and the size of the fixing ring for fixing the funnel is fixed. Thereby it is not suitable for fixing smaller funnels, and the beakers are all placed on the table top, so they are easy to shake. Contents of the invention [0004] The object of the present invention is to provide a kind of filtration experimental device for chemical experiments, to solve the ...
