The present invention relates to the technical field of calcium oxide preservation appliances, and discloses a calcium oxide waterproof and deteriorating preservation device for testing, which includes a preservation bottle. Rotary column, the outer side of the second rotating column is connected with a connecting rod, the connecting rod is connected with a plugging leaf, the upper end of the sliding bottom plate is provided with an expansion strip, the middle part of the outlet pipe is provided with a groove, and the lower part of the outlet pipe is provided with a sliding groove. There is a fastening device connected to the outer side of the upper part of the tube. Water droplets enter the inside of the outlet tube and slide down along its inner wall. The expansion strip expands and pushes the sliding bottom plate to slide downward in the sliding groove. The sliding bottom plate drives the support column through the second bearing to push the turntable to Moving down, the turntable drives the connecting rod to move through the second rotating column on it, and the connecting rod drives the sealing leaf to rotate around the first rotating column, and the sealing leaf is closed. This structure solves the problem that the existing ordinary calcium oxide bottle is not waterproof. The problem of splash deterioration.
Description
technical field [0001] The invention relates to the technical field of calcium oxide preservation appliances, in particular to a calcium oxide anti-splash and deterioration preservation device for testing. Background technique [0002] Calcium oxide, also known as quicklime, has the chemical formula CaO and is a common inorganic compound. The usual method is to calcinate natural rocks whose main component is calcium carbonate at high temperature to decompose into carbon dioxide and calcium oxide. All natural rocks with calcium carbonate as the main component, such as limestone, chalk, dolomitic limestone, etc., can be used to produce lime. Quicklime is a common desiccant used to remove water vapor by chemical absorption. When used as an analytical reagent, it is used as an absorbent for carbon dioxide and sulfur dioxide in gas analysis, as a spectral analysis reagent, and as a high-purity reagent for epitaxy and diffusion in semiconductor production. Laboratory ammonia dry...
