Problems solved by technology

The glass liner of the ordinary thermos bottle must be smashed to take out the sample after the reaction is completed, which is very easy to hurt people and cause a lot of waste; the mouth of the ordinary thermos bottle is not easy to seal, and there is air leakage that affects the constant temperature effect. Chemical synthesis reaction is extremely unfavorable

Abstract

The invention discloses an electric heat constant-temperature chemical reaction pot relating to a laboratory reaction pot which can keep the temperature of heat energy in chemical reaction constant and is formed by utilizing a vacuum heat insulation and partially electric heating technology. The Electric heat constant-temperature chemical reaction pot comprises a stainless steel vacuum heat insulation pot body, an upper stainless steel vacuum cover, a rubber plug, a thermometer, an air intake pipe, an exhaust pipe and an external heating device, wherein a rubber plug mounting hole is formed at the middle part of the upper stainless steel vacuum cover and is provided with the rubber plug, the upper stainless steel vacuum cover is mounted at the upper part of the stainless steel vacuum heat insulation pot body, a rubber seal ring is arranged between the upper stainless steel vacuum cover and the stainless steel vacuum heat insulation pot body, and the external heating device is arranged on the upper stainless steel vacuum cover; and the rubber plug is provided with an air vent, a feeding hole and a thermometer pocket which are respectively provided with a vent pipe, a feeding pipe and the thermometer. The external heating device is provided with an electric heating element, a temperature control element, a heating indicating device, a timing device and a time display device.

Description

technical field [0001] The electric heating constant temperature chemical reaction tank of the present invention relates to a laboratory reaction tank for maintaining constant temperature of thermal energy in chemical reaction formed by utilizing vacuum heat preservation and local electric heating technology. Background technique [0002] In petroleum, petrochemical, textile, papermaking, daily chemical and other extensive chemical and chemical fields, there are certain requirements on temperature in chemical synthesis reaction tests. At present, the chemical reaction devices suitable for this type of chemical reaction that can be sealed and kept constant in the laboratory are mainly small reaction kettles. This type of equipment generally uses double-layer glass circulating liquid heating to maintain the test temperature in the chemical reaction. There are problems such as complex equipment structure, high price, cumbersome circulating liquid heating operation, etc., and it...
