Description

Double-box oven for laboratory Technical Field The utility model relates to the technical field of laboratory ovens, in particular to the technical field of a double-box oven for a laboratory. Background The laboratory oven is a test device commonly used in a laboratory and mainly comprises a temperature control device, a heating device, a box body, a placing tray and the like, and is mainly used for drying various washed test instruments or some test products. Most ovens used in the laboratory at present are provided with only one oven body, and the oven of one oven body has the problems of small volume, low drying efficiency and the like, so that the working efficiency is greatly influenced. For solving the problem that proposes among the above-mentioned technique, for example, application number CN201721095827.0 discloses a special box of experimental double-box oven, including the special box of big volumetric flask thing, the special box center of big volumetric flask thing is equipped with carries bottle rack, the special box inner wall of big volumetric flask thing is equipped with the impeller air outlet, the special box of big volumetric flask thing openly is equipped with amortization noise reduction door, amortization noise reduction door surface mounting has anti-skidding handle, the special box upper surface of big volumetric flask thing is equipped with the air regulation gas vent, and the double-box oven for this kind of experiments adopts double-box structure, can satisfy scientific research in-process, once only is equipped with two bottle racks to the demand of drying of big batch container bottle, and the left side of this double-box oven is provided with three bottle racks, and the right side can classify the stoving to the bottle, and the bottle that highly is higher is placed in right side box, and the bottle that highly is lower is placed in left side box to utilize the oven space, and this double-box is all set up at the impeller air outlet of three face air outlet of oven for the uniform circulation bottle. However, the ventilation opening of the oven in the above patent is not provided with a device for filtering the gas in the oven, and some toxic and harmful gas can be generated during the drying of the experimental product, meanwhile, the accumulated dust can not be cleaned after the ventilation opening is used for a long time, and the ventilation opening has potential threat to environmental sanitation and the health of experimental personnel.
