Thermostatic type dual-layer overturn oscillator

Abstract

The invention discloses a thermostatic type dual-layer overturn oscillator, and relates to the technical field of analysis and detection equipment in a lab. The thermostatic type dual-layer overturn oscillator comprises a work case (1), a frame (16) in the work case, an upper layer overturning device, an upper layer overturning transmission system, a lower layer overturning device, a lower layer overturning transmission system, and an electric cabinet (6), and also comprises a thermostatic system composed of an air conditioner (2) and a heating assembly. The air conditioner (2) is arranged onthe upper part of the right outer surface of the work case (1). The air conditioner (2) is communicated with the inner cavity of the work case (1) through an air returning hole (20) in the upper partof the air conditioner (2) and an air blowing hole (31) arranged in the lower part of the air conditioner (2) and forms air circulation in the work case (1). The heating assembly comprises at least two heating plates (17), which are arranged on the middle-lower positions of the rear inner surface of the work case (1). The oscillator has the characteristics of controllable temperature, lightness, small volume, and low production cost, and is suitable for sample extraction in labs of following industries: tobacco, food, medicines, chemical engineering, and the like.

Description

technical field [0001] The invention relates to the technical field of laboratory analysis and detection equipment, in particular to a constant temperature type double-layer inversion oscillator. Background technique [0002] In the laboratory, the chemical analysis of various substances or the extraction test of harmful substances requires the samples to be put into test bottles, sealed and shaken before analysis or extraction. There are mainly two types of oscillators: horizontal type and flip type. Most of the existing flip type oscillators adopt an open method, so that the extraction temperature cannot be controlled. At the same time, most of the jigs used for clamping the test bottles are made of solid materials. These solid parts have large processing capacity, relatively heavy weight and high production costs. [0003] The Chinese Patent (Patent Application No. 201220399301.2) discloses "a flipped oscillator with uniform temperature and double-sided clamping", which ...

Problems solved by technology

There are mainly two types of oscillators: horizontal and flipped. Most of the existing flipped oscillators are open, so that the extraction temperature cannot be controlled.

At the same time, most of the fixtures used to clamp the test bottle are made of solid materials. These solid parts have large processing volume, heavy weight and high production cost.
