Chemical instrument with dustproof device

Abstract

The invention provides a chemical instrument with a dustproof device, and belongs to the technical field of chemical instrument dust prevention. The chemical instrument with the dustproof device comprises a dustproof box, a protection box, two connecting blocks and an instrument body, wherein the protection box is fixed at the upper end of the dustproof box; the two connecting blocks are positioned on the front side of the protection box; the instrument body is fixed on the lower inner wall of the dustproof box; dustproof plates are movably hinged to the front ends of the dustproof box and theprotection box through hinges; dustproof glass is arranged at the front end of each dustproof plate; the dustproof glass is positioned on the front side of the instrument body; an instrument inner disc is arranged on the inner side of the instrument body; the front end of the instrument inner disc is rotatably connected with a pointer; and a slideway is formed in the front end of each dustproof plate. The chemical instrument with the dustproof device aims to solve the problems that a chemical instrument is generally exposed out of chemical equipment, dust in air is prone to being attached tothe chemical instrument, internal numerical values of the chemical instrument are not easy to see clearly and the quality of chemical products in the production process in the prior art is affected.

Description

technical field [0001] The invention belongs to the technical field of dustproofing of chemical instruments, and in particular relates to a chemical instrument with a dustproof device. Background technique [0002] In the prior art, instruments are the general term for instruments that display numerical values, including pressure instruments, flow instruments, and various analytical instruments. Chemical industry is the abbreviation of "chemical process", "chemical industry", and "chemical engineering". Any technology that uses chemical methods to change the composition and structure of substances or to synthesize new substances belongs to chemical production technology, that is, chemical technology. The resulting products are called chemicals or chemical products. Chemical instruments are used to detect and control the process parameters of chemical processes Advanced automation technology tools can accurately and timely detect changes in various process parameters.
