Abstract
The utility model provides a sandwiched round-bottom flask. The sandwiched round-bottom flask comprises a round bottom part and a flask opening part of a flask. The sandwiched round-bottom flask is characterized in that the round bottom part comprises a round wall at the inner layer and a round wall at the outer layer; a hollow cavity body is arranged between the two layers of round walls; the round wall at the outer layer is provided with a water inlet and a water outlet which are communicated with the hollow cavity body. According to the utility model, an existing round-bottom flask is improved, the round-bottom part is arranged into a hollow structure with the round walls at the inner layer and the outer layer, and the outer wall is provided with the water inlet and the water outlet, so that after the reaction in the sandwiched round-bottom flask is completed, products in the flask can be cooled down rapidly by introducing water or other media from the water inlet. The sandwiched round-bottom flask provided by the utility model is safe and convenient, is easy to implement, and has very high practicability.
Description
Technical field
The utility model relates to the chemical experimental instrument field, specifically refers to a kind of interlayer round-bottomed flask.
Background technology
Round-bottomed flask generally is used as under the heating condition, and the reaction vessel of liquid participation is arranged, and is widely used in the various chemical experiments such as extraction of chemical reaction, natural products.At present, laboratory its round bottom of round-bottomed flask commonly used partly is single layer structure.And the experiment reaction temperature when using round-bottomed flask is when higher, when after reaction finishes, needing mobile round-bottomed flask, during the shift experiment sample or other laboratory sample requirement fast coolings and when cooling off, then can bring many inconvenience and unnecessary security incident.
Summary of the invention
The purpose of this utility model is to provide a kind of interlayer round-bottomed flask according to above-mentioned deficiency, and this interlayer round-bottomed flask can make laboratory sample fast cooling in round-bottomed flask and the flask after reaction finishes.
The utility model is achieved by the following technical solution:
A kind of interlayer round-bottomed flask, it comprises flask round bottom part and bottleneck portion, it is characterized in that described round bottom partly is inside and outside two-layer round wall, is hollow cavity between two-layer round wall, outer circle wall is provided with water inlet and the delivery port that communicates with hollow cavity.
Preferred described water inlet and delivery port are symmetrically distributed on the skin circle wall of bottleneck both sides.
The utility model improves existing round-bottomed flask, partly be set to the inside and outside two-layer round wall construction of hollow at round bottom, and be provided with water inlet and delivery port at outer wall, after making the reaction end in the interlayer round-bottomed flask, can from water inlet, feed water or other media to the product fast cooling in the flask.The utility model safe ready implements to have very strong practicality easily.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
1. bottleneck portion, 2. water inlet, 3. delivery port, 4. outer wall, 5. inwall, 6. hollow cavity.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model interlayer round-bottomed flask comprises flask round bottom part and bottleneck portion 1, and described round bottom is that inwall 5 and outer circle wall are outer wall 4 for internal layer circle wall partly, and 5 of outer wall 4 and inwalls are hollow cavity 6.On the outer wall 4 of bottleneck portion 1 both sides, symmetry be provided with water inlet 2 and the delivery port 3 that communicates with hollow cavity 6.
When using interlayer round-bottomed flask of the present utility model to carry out heating and refluxing extraction or other heating experiment, owing to use the experimental temperature of round-bottomed flask higher, and require mobile round-bottomed flask afterwards, shift experiment sample or laboratory sample require fast cooling and cooling, then condensed water can be inserted water inlet 2, condensed water progressively spreads in hollow cavity 6 to whole cavity, carry out heat exchange by the laboratory sample in inwall 5 and the round-bottomed flask, condensed water behind the absorption heat flows out from delivery port 3, can cool off by being connected to refrigerating plant, feed again again carry out in the water inlet 2 recycling.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. interlayer round-bottomed flask, it comprises flask round bottom part and bottleneck portion, it is characterized in that described round bottom partly be inside and outside two-layer round wall, be hollow cavity between two-layer round wall, skin is justified wall and is provided with water inlet and the delivery port that communicates with hollow cavity.
2. according to the described interlayer round-bottomed flask of claim 1, it is characterized in that: described water inlet and delivery port are symmetrically distributed on the skin circle wall of bottleneck both sides.
