Description
Technical Field
[0001] The utility model belongs to the technical field of chemical experimental devices and relates to an oil heater. Background Art
[0002] In the process of chemical experiments, the problem of oil stratification often occurs due to long-term storage. The existing preheating methods often have high labor costs and are difficult to preheat the oil. However, during the preheating process, the sample is easily exposed to air, resulting in oxidation. Oxidation products will reduce the quality of the oil, leading to increased viscosity, increased acid value, darker color, etc.; they will also affect the performance and life of the oil. If there are too many oxidation products in the oil heating device, the oil will be heated unevenly and local overheating will occur. This may cause safety accidents such as fire and explosion.

The silicone rubber oil drum with heating and heat preservation functions is provided with a heat preservation layer and a heater. The setting of the heat preservation layer and the heater can continuously heat the silicone rubber liquid, and can also be heat-insulated after heating to prevent the silicone rubber liquid from solidifying after cooling, and finally affecting the later processing. The above-mentioned heating device only considers the heating and heat preservation problems, and does not consider the problem of oxidation and generation of oxidation products when the oil comes into contact with air during the preheating process.
