Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to an extraction and distillation device with a protective function. Background Art

[0002] In the chemical industry, for some solutions with very small differences in boiling points (volatility) of various components, extraction distillation is usually used to separate different components. In the prior art extraction distillation process, it is necessary to use a condenser to collect the components after separating each group of components. For example, a patent with patent announcement number CN211963135U records an extraction distillation safety protection device, in which the scheme recorded is: the arc plate moves on the side wall of the shell, and the arc plate blocks the shell to avoid damage to the condenser by external collision. The condenser is conveniently disassembled and fixed by the clamping mechanism, and the connection and disassembly of the extraction distillation device is realized by the connecting sleeves on the upper and lower sides of the condenser; the existing problems are: the condenser shrinks due to cold during the condensation extraction process, which loosens the clamping mechanism to fix the condenser, and the device can only be used to fix condensers of one diameter, and the scope of application is small.

[0003] Based on this, an extraction distillation device with a protective function is now provided to eliminate the disadvantages of the existing device. Utility Model Content

[0004] The utility model aims to provide an extraction and distillation device with a protective function to solve the problems in the background technology.
