Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a multifunctional evaporator for experimental detection. Background Technique

[0002] The evaporator is a very important component among the four major components of refrigeration. It is a closed heat exchange device. The evaporator mainly consists of a heating chamber and an evaporation chamber. The heating chamber provides the heat required for the liquid to evaporate, promoting the liquid to boil and vaporize; the evaporation chamber completely separates the gas-liquid two-phase.

[0003] According to the utility model patent with the publication number CN215464528U, a multifunctional evaporator for experimental detection, one end of a cross bar is attached to a first condenser tube. One side of the first condenser tube is attached to one side of a groove on the front surface of a cross plate. The first condenser tube is connected to a second condenser tube through a rubber tube above it. The utility model relates to the technical field of evaporation. Through the cooperation among the cross bar, the cross plate and a first handle, when a user installs the first condenser tube, first pull the first handle to drive the cross bar to move, and then connect the first condenser tube to a distillation flask. A spring is used to replace the conventional bolt fixing method, solving the problem that in the existing device, when working, bolts are used to fix the condenser tube. The disadvantage is that if the force is not well controlled, it is very easy to cause damage to the condenser tube, and the bolts are exposed in a place with a lot of water vapor for a long time, which will accelerate the rusting speed and cannot work normally, improving the practicability.

[0004] Through the above structures such as the cross bar, the cross plate and the first handle, the situation that it is very easy to cause damage to the condenser tube due to poor force control is prevented. However, after the first condenser tube is fixed through structures such as the cross plate, the height of the condenser tube and the distillation flask is inconvenient to adjust, and the heater is in an unsealed state, and the generated heat is easily dissipated to the outside, reducing the utilization rate of resources.

Since the sealing cover 202 covers the top end of the heater 201, the heat generated by heating is not easily dissipated to the outside. At the same time, start the blower 204, and draw the hot air generated by the evaporation of water into the heating box 205 through the air inlet pipe 203, and then discharge it through the air outlet plate 207 after secondary heating by the heating rod 206, so as to realize the recycling of the heat of evaporation and improve the utilization rate of resources.
