Isothermal self-compensating type liquid level adjusting water bath kettle

Abstract

The invention relates to an isothermal self-compensating type liquid level adjusting water bath kettle which comprises a water bath kettle body, a first temperature controller for controlling the temperature of a water bath area of the water bath kettle, and a water supplementing tank, a first liquid level controller (1), a second liquid level controller (2) and a second temperature controller, wherein the water bath kettle body is arranged in the water supplementing tank, a liquid level water supplementing area (7) is arranged between the inner wall of the water supplementing tank and the outer wall of the water bath kettle body, the first liquid level controller (1) is arranged at a lower part of the water bath kettle body and is used for control water input when the liquid level of a water bath kettle water bath area (6) is too low, the second liquid level controller (2) is arranged at an upper part of the water supplementing tank and is used for control water input when the liquid level of the liquid level water supplementing area (7) is too low, and the second temperature controller is used for controlling the temperature of the liquid level water supplementing area (7) to keep consistent with the temperature of the water bath kettle water bath area (6). The isothermal self-compensating type liquid level adjusting water bath kettle can realize the function of unmanned water self-compensation (water at the same temperature).

Description

Technical field: [0001] The invention belongs to the field of small laboratory equipment and relates to an automatic compensation function for the liquid level of a water bath. Background technique: [0002] The water bath is a small equipment often used in the laboratory. It can provide a uniform and stable temperature, so many chemical reactions need to be carried out in the water bath. It 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, education and scientific research. In the experiment, the chemical substance is usually placed in a container first, and then the container is put into the water in the water bath. It is required to completely immerse the part containing the chemical substance in the water to obtain a uniform and stable temperature for the chemical reaction to occur....

AI Technical Summary

Problems solved by technology

However, the current water bath only has the function of automatic temperature adjustment, and there is no automatic compensation function of liquid level, which is its main defect

Because with the evaporation of water in the pot, the liquid level will inevitably drop, which makes the chemical reaction substances put into it cannot be immersed in the water bath environment all the time, which has a great impact on the chemical reaction and makes the chemical reaction incomplete. Seriously affect scientific research results

Therefore, in the process of use, sometimes it is necessary to add water artificially, but the temperature of the added water is often inconsistent with the water temperature in the water bath, which will cause the suspension of the chemical reaction or other side reactions.
