Abstract
A seal device for a distillation flask belongs to the technical field of chemical apparatus equipment and comprises the distillation flash, a seal cover installed on the distillation flask and a connection pipe. The lower end of the connection pipe penetrates through the seal cover to extend into an inner cavity of the distillation flask, a filtering layer enabling gas to pass through is filled in an inner cavity of the connection pipe, and soda lime particles are arranged in the filtering layer. The connection pipe is added and is communicated with the inner cavity of the distillation flask, and the filtering layer is arranged in the inner cavity of the connection pipe, the soda lime particles are arranged in the filtering layer, and therefore, distilled water obtained by the inner cavity of the distillation flask through distillation can exchange heat with the outside air to enable cooling speed to be accelerated. Due to the fact that carbon dioxide gas reacts with the soda lime particles when entering the connection pipe, the carbon dioxide gas cannot enter the distilled water so as to ensure purity of the distilled water. The seal device for the distillation flask is simple in structure and simple in operation step.
Description
Technical field
The utility model relates to the chemical apparatuses equipment technical field, refers to a kind of distilling flask sealing device especially.
Background technology
Prepared in laboratory distilled water requires in the distilled water not carbonated.Present operating procedure is to be positioned in the closed container through the distilled water that high temperature distillation obtains, and lets hyperthermal distilled water slowly cool off, this operating procedure trouble, and distilled water is long cool time.
The utility model content
The purpose of the utility model is to provide a kind of distilling flask sealing device, and it is simple in structure, it is guaranteeing that carbon dioxide does not get under the prerequisite of distilled water, and the cooling velocity of distilled water is fast, and operating procedure is simple.
To achieve these goals; The technical solution of the utility model is: a kind of distilling flask sealing device; Comprise distilling flask and be installed on the seal cover on the distilling flask that wherein also comprise tube connector, the inner chamber that stretches into distilling flask behind the said seal cover is passed in the lower end of said tube connector; The inner chamber of said tube connector is filled with the filter course that gas can pass through, and is placed with the soda lime particle in the said filter course.
The utility model distilling flask sealing device; Wherein said tube connector is by vertically constituting to first pipe that is provided with and the funnel-form second pipe one that is positioned at the first pipe lower end; The lower end cross-sectional area of said second pipe is less than the upper end cross-sectional area, and the inner chamber that stretches into distilling flask behind the said seal cover is passed in the lower end of said second pipe.
The utility model distilling flask sealing device, wherein said filter course are cotton layer.
After adopting such scheme, the utility model distilling flask sealing device makes tube connector be communicated with the distilling flask inner chamber through on existing distilling flask seal cover, connecting tube connector; In the filter course that this tube connector inner chamber placement gas possibly crossed; The distilled water that the distilling flask inner chamber is obtained can carry out heat exchange with outside air, make the cooling velocity quickening of distilled water, and extraneous carbon dioxide is owing to the reaction of the soda lime particle in elder generation and the filter course in getting into tube connector; Carbon dioxide can not get in the distilled water; Guaranteed the pure of distilled water, this apparatus structure is simple, and operating procedure is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model distilling flask sealing device.
Below in conjunction with accompanying drawing, the utility model is done further explanation through embodiment;
The specific embodiment
See also shown in Figure 1ly, the utility model distilling flask sealing device comprises distilling flask 1, is installed on seal cover 2 and tube connector 3 on the distilling flask 1.Tube connector 3 is by vertically constituting to first pipe 6 that is provided with and funnel-form second pipe 7 one that are positioned at first pipe, 6 lower ends.The lower end cross-sectional area of second pipe 7 is less than the upper end cross-sectional area.The inner chamber that stretches into distilling flask 1 behind the seal cover 2 is passed in second pipe, 7 lower end.The inner chamber of tube connector 3 is filled with the filter course 4 that gas can pass through, and filter course 4 is a cotton layer.Be placed with the soda lime particle in the filter course 4.
In the use, distilling flask 1 inner chamber can carry out heat exchange with outside air through the distilled water that distillation obtains, and has accelerated the cooling velocity of distilled water; And extraneous carbon dioxide is owing in getting into tube connector 3 time, react with the soda lime particle earlier, and the soda lime particle is with the carbon dioxide gas bulk absorption; Make carbon dioxide can not get in the distilled water; Guaranteed the pure of distilled water, this apparatus structure is simple, and operating procedure is simple.
The above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
