Flask with cooling structure for chemical laboratory

Abstract

The invention discloses a flask with a cooling structure for a chemical laboratory. The flask with the cooling structure for the chemical laboratory comprises a flask body, a flask mouth and a flask base. The flask with the cooling structure for the chemical laboratory is provided the flask base, so that a round-bottom flask can be effectively prevented from dumping and then the flask can be placed more stably, furthermore, the heating bottom of the flask body is flush with the bottom of a support frame, thereby not affecting the heating for the flask; in addition, a flask outer bottle is fixedly arranged on the contact surface of the inner part of the flask base and the flask body, a water-cooled tube is fixed on the outer wall of the flask outer bottle, when the flask is heated, coolingliquid is not injected into the water-cooled tube, so that the heating temperature is not affected, and when the flask requires to be cooled, the cooling liquid is injected to the water-cooled tube, to take away the heat of the flask outer bottle so as to lower the temperature of the flask body, and then cold water is effectively prevented from directly contacting with the flask to prevent explosion of the flask. A cooling fan is controlled, thereby being capable of accelerating the cooling of the heating bottom of the flask with higher temperature.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a flask with a cooling structure used in a chemical laboratory. Background technique [0002] The flask is unobstructed and has the appearance of a round belly and a thin neck. It is divided into single-necked flasks and multi-necked flasks. Among the multi-necked flasks, three-necked flasks and four-necked flasks are more commonly used. Three-necked flasks and four-necked flasks can add multiple reactants at the same time, or Add condenser. When the solution needs to react for a long time or heat to reflux, generally all can choose to use the flask as the container. At present, chemical laboratories in schools or scientific research units often use flasks for small reaction tests. When heating flasks, glass products generally need to be covered with asbestos mesh on the flame to make the heating even and prevent the flask from being heated during the heating pr...

AI Technical Summary

Problems solved by technology

At present, chemical laboratories in schools or scientific research units often use flasks for small reaction tests. When heating flasks, glass products generally need to be covered with asbestos mesh on the flame to make the heating even and prevent the flask from being heated during the heating process. Uneven and burst. When the flask is cooled, it is usually air-cooled. It cannot be directly placed in cold water to cool it. In the experiment, because the students were impatient, they directly cooled with cold water to cause the flask to crack.

Air-cooled flasks, for a flask with a capacity of 1000ml, simple stirring + air cooling generally takes one hour, and the cooling time in summer is longer, which seriously affects the efficiency of the experiment. It is necessary to design a chemical laboratory with a flask with a cooling structure to solve these problems
