Chemical solid-liquid reaction experiment demonstration device

Abstract

The invention relates to an experiment demonstration device, and especially relates to a chemical solid-liquid reaction experiment demonstration device. The technical problem to be solved is to provide a chemical solid-liquid reaction experiment demonstration device which is high in automation degree, good in safety and simple in experiment process. In order to solve the above technical problem, the invention provides a chemical solid-liquid reaction experiment demonstration device comprising a base plate, a first support bar, bearing pedestals, a nut, a screw, a second support bar, a first motor, a slide rail, a guide block, a third support bar, an alcohol burner, a heating net, a beaker, a casing, a top board, an electric push rod, a rotating motor, a stirring bar, stirring vanes, a funnel, an electric controllable valve, a second motor, a thumb cylinder, a measuring cylinder and a travel switch. The bearing pedestals are symmetrically arranged on the central part of the top of the base plate, the screw is arranged on the two bearing pedestals, and the nut is arranged on the screw. The chemical solid-liquid reaction experiment demonstration device is high in automation degree, good in safety and simple in experiment process.

Description

technical field [0001] The invention relates to an experimental demonstration device, in particular to a chemical solid-liquid reaction experimental demonstration device. Background technique [0002] Chemistry in the 20th century is a science based on experiments. Experiments and theory have always been two aspects that are mutually dependent and mutually reinforcing in chemical research. After entering the 20th century, due to the influence of the development of other disciplines of natural science and the extensive application of contemporary scientific theories, techniques and methods, chemistry has made great progress in understanding the composition, structure, synthesis and testing of substances, etc. Moreover, many important achievements have been made in theory. On the basis of the four major branches of inorganic chemistry, analytical chemistry, organic chemistry and physical chemistry, a new branch of chemistry has emerged. [0003] Demonstration devices used fo...
