Water bath kettle with clamping device

Abstract

The invention discloses a water bath kettle with a clamping device. The water bath kettle comprises a tank body, a water channel and a control cabinet, wherein an air pump is arranged in the control cabinet and is connected with a gas piping, and the gas piping penetrates in from the top of the water channel and out from the bottom of the water channel; a storage plate horizontally arranged is arranged in the water channel, a plurality of clamping devices are arranged on the storage plate, each clamping device comprises a containing hole formed in the storage plate, a plurality of elastic elements are arranged on the containing hole, all the elastic elements are connected with clamping assemblies, and the adjacent clamping assemblies can be matched with each other and connected. Different shapes of containers in the water channel can be stabilized, an automatic water supply device is arranged, the tank body is heat-insulating and energy-saving, and the water bath kettle has the advantages of being short in heating time, uniform in water temperature, high in accuracy of experiment results, wide in application range, good in scale-preventive performance, high in safety performance and the like, and is good in usability and worthy of wide popularization.

Description

technical field [0001] The invention relates to the technical field of laboratory equipment, in particular to a water bath with a clamping device. Background technique [0002] The water bath is mainly used for distilling, drying, concentrating and warming chemicals or biological products in the laboratory. It can also be used for constant temperature heating and other temperature tests. It is an essential tool for laboratories in the fields of food, biology, aquatic products, environmental protection, and medicine. . A stainless steel tubular heater is placed horizontally in the constant temperature water bath, and an aluminum shelf with holes is placed inside the water tank. The upper cover is equipped with combined ferrules of different calibers, which can be adapted to flasks of different calibers. There is a water discharge pipe on the left side of the water bath, and the electric box is on the right side of the constant temperature water bath. The temperature control...

Problems solved by technology

But still there are following defects: one, when the water bath is heated in a water bath, the water in it produces a buoyancy effect, which often makes the reaction vessel float and fix unstable. However, its fixation effect is not good, which causes troubles to the experimental process and also affects the experimental results; secondly, with the heating of the water bath, the water evaporates and the liquid level drops, and the water bath does not have an automatic liquid level compensation device, so that The chemical reaction substances put in it cannot be immersed in the water bath environment all the time, which will affect the chemical reaction and then affect the experimental results. At the same time, it is very easy to cause safety accidents in the water bath pot. Made of good materials, such as aluminum and copper, when heated, due to the heat transfer of the box wall, a large amount of heat is wasted, and the heat utilization rate cannot be used in the case of high temperature accuracy requirements, and the heating time is long and the efficiency is low.
