Thermostatic water bath kettle sealed and insulated by floats and application method thereof

Abstract

The invention discloses a thermostatic water bath kettle sealed and insulated by floats. The thermostatic water bath kettle comprises a water tank and floats disposed in the water tank. The floats are 2-30mm in diameter. At least two layers of floats are horizontally placed on the maximum-section plane of the water tank, forming a seal insulating layer for the water tank. The invention further discloses an application method of the thermostatic water bath kettle. The seal insulating layer formed by the floats replaces the existing insulation partition cover plate and is better than the prior insulation partition cover plate in tightness and insulation; neither the insulation partition cover plate nor a reducing ring needs to be used when a test vessel is placed in the water tank; any type of test vessel can be placed in the water tank directly; more test vessels compared to the prior art can be placed in the water tank once; the effective heating space of the water tank of the thermostatic water bath kettle can be given to full play.

Description

technical field [0001] The invention relates to a water bath used for constant temperature heating of test vessels in a laboratory, in particular to a constant temperature water bath. Background technique [0002] The constant temperature water bath is mainly used for distillation, drying, concentration, and warming of chemicals or biological products in the laboratory. It can also be used for constant temperature heating and other temperature tests. An essential tool for laboratories, analysis rooms, education and scientific research. Existing constant temperature water bath comprises water tank 1 and insulation separation cover plate 8, as Figure 2~3 As shown, the insulation partition cover plate is installed on the upper mouth of the water tank 1, and several partition holes with different apertures are opened on the insulation partition cover plate 8, so as to adapt to the separation and placement requirements of various specifications of test vessels to be heated.

AI Technical Summary

Problems solved by technology

But there are many variable collars 9 that need to be equipped, and the test vessels that are simultaneously put into the water tank 1 are limited, so the effective heating space of the constant temperature water bath can not be fully utilized, and the operation is very inconvenient. It is not ideal, the thermal insulation performance is not high, the temperature at the bottom is high, and the temperature at the top is low, which has a great impact on the accuracy, stability and coincidence of the test
