A large-capacity high-precision liquid constant temperature bath

Abstract

The invention belongs to the technical field of liquid thermostatic equipment, and relates to a large-volume high-precision liquid thermostatic bath. The large-volume high-precision liquid thermostatic bath comprises a thermostatic bath body, a top cover, stirrers, a metal partition with holes, heaters, and observation windows, wherein the top cover is arranged on the upper surface of the thermostatic bath body; the stirrers, the metal partition with the holes, the heaters and a liquid are all arranged in an inner chamber formed by the thermostatic bath body; heat-insulating materials are arranged outside the thermostatic bath body and on the inner wall of the top cover. The large-volume high-precision liquid thermostatic bath is characterized in that a plurality of holes are formed in the top cover, three layers of stirring blades are mounted on each stirrer, and the stirring blades are inserted in the liquid in the thermostatic bath body; the heaters are inserted in the liquid in the thermostatic bath body; the metal partition with the holes divides the thermostatic bath body into a working area and a temperature control area; the stirrers and the heaters are all arranged in the temperature control area. The large-volume high-precision liquid thermostatic bath with the observation windows provided by the invention can meet the requirements for the working volume, temperature range, temperature control precision and observability of a thermostatic environment.

Description

technical field [0001] The invention relates to the technical field of liquid constant temperature equipment, in particular to a large-capacity and high-precision liquid constant-temperature tank, which is suitable for use occasions requiring a large-capacity constant-temperature environment. Background technique [0002] The constant temperature bath is a tank that can provide a constant temperature environment. It is widely used in various fields such as medicine and health, petrochemistry, biology, and food industry. It is an essential equipment for temperature measurement and scientific research. [0003] In recent years, with the rapid development of key technologies in related fields, higher requirements have been put forward for the constant temperature environment, not only requiring high temperature control accuracy and wide temperature range, but also requiring the ability to provide a large capacity constant temperature environment with an observation window It is...

AI Technical Summary

Problems solved by technology

It can be seen from the table that the temperature control accuracy of the domestically produced thermostatic bath is relatively low and the working volume and height are limited; the thermostatic bath produced by the famous foreign thermostatic bath manufacturer Fluke has a high temperature control accuracy, but either the working volume is limited, such as 6022 The working volume of the type constant temperature bath is only 27L, or the temperature range is limited, such as the maximum temperature of the 7009 type resistance constant temperature bath is only 50°C, and there is no observation window

To sum up, none of the existing constant temperature baths can meet the requirements of temperature control accuracy, temperature zone range, working volume and observability at the same time.
