Description

Multi-layer dryer

Technical Field

The utility model relates to a container or household utensils field that the laboratory was used, more specifically relate to a multilayer desicator.

Background

The dryer is a sealed container commonly used in laboratories and is mainly used for drying aqueous samples and holding supersaturated solutions of salts to maintain a certain relative humidity. Before use, the supersaturated solution of desiccant or salt is placed in a dryer, and vaseline is applied to the gap to ensure the interior of the container to be sealed. Sometimes, the cover is lifted up by the expansion of air when the hot object is placed in the dryer, for example, when ash content is tested, the burned crucible is placed in the dryer to be cooled to room temperature. In addition, negative pressure is easily generated in the dryer due to expansion with heat and contraction with cold or adsorption of the drying agent, and the cover is not easy to open. In order to avoid the above-mentioned situation, it is necessary to ventilate the dryer by opening the lid during or after the experiment to balance the pressure in the dryer, so that the use of the dryer is very inconvenient.

Chinese patent specification CN205919631U discloses a glass dryer comprising a plurality of layers of baffles arranged within the dryer, the baffles comprising a recessed tray structure forming a cavity and a perforated plate overlying the tray structure. The dryer increases the capacity by arranging a plurality of layers of partition plates, and improves the drying efficiency by arranging a disc body structure at each layer of partition plate. Although the dryer can be ventilated by opening the cover, the opening of the cover is large, so that when the experimental sample needs to be kept in a certain relative humidity environment, the stable environment in the dryer is easy to damage. In addition, the cover is not easily opened when negative pressure is formed in the dryer. Therefore, it is necessary to provide the dryer with an exhaust port to achieve pressure equalization in the dryer. However, even if the dryer has an exhaust port, the air is blocked by the tray structures disposed on the respective layers, and cannot smoothly circulate between the partition plates on the respective layers, so that the air in the dryer cannot be sufficiently released or the negative pressure cannot be sufficiently balanced.
