Slowly heating water bath heating equipment

Abstract

The invention discloses slowly heating water bath heating equipment, which comprises an outer shell and an inner shell. The inner shell is sleevedly arranged in the outer shell. The outer shell is in a cylindrical shape. A connection cover is arranged between the upper end face of the inner shell and the upper end face of the outer shell. The connection cover is provided with a liquid inlet and a gas outlet, and the gas outlet is in a tapered shape. The inner shell comprises an outer sleeve pipe and an inner sleeve pipe. The lower end of the inner sleeve pipe is sleevedly connected to the interior of the outer sleeve pipe. The upper end of the outer sleeve pipe is provided with a water outlet. The lower end of the outer sleeve pipe is provided with a water inlet. The included angle between the water outlet and the lateral wall of the outer sleeve pipe is 45 degrees. The included angle between the water inlet and the lateral wall of the outer sleeve pipe is 45 degrees. The opening directions of water inlet and water outlet are opposite. The lower end face of the outer shell is in a semi-spherical shape. The provided water bath heating equipment can overcome the shortages of prior art, and moreover, the structural design is reasonable and novel.

Description

technical field [0001] The invention relates to a slowly heating water bath heating equipment, which belongs to the field of teaching equipment. Background technique [0002] Fill a large container with water first, then place the container to be heated into the container where the water was added. Heating a large container of water is achieved by heating the water in the large container and then transferring heat (heat transfer) through the water to the container that needs to be heated to achieve the purpose of heating. Because at one standard atmospheric pressure and water without any impurities, the condition for water to reach the boiling point is 100 degrees Celsius, but it needs to absorb more heat to change from liquid to gas. In the water bath method, the water in the beaker can only have a temperature of 100 degrees Celsius before it turns into water vapor, which cannot provide more heat for the water in the test tube, so the liquid in the test tube cannot boil. ...

AI Technical Summary

Problems solved by technology

But sometimes, when heating some dangerous items, if the heating speed is too fast, there will be dangers such as explosion due to rapid expansion or a large amount of gas emission, so slow heating is required

However, the existing water bath heating equipment, especially the simple equipment for classroom demonstration, cannot achieve the purpose of adjusting the heating speed, which affects the progress of the experiment
