Abstract

A liquid concentrating apparatus comprises a temperature control water-bath system and a negative pressure tank; the temperature control water-bath system comprises a water bath, the water bath is provided with a water injection hole, and a temperature measurement probe and a heating device are arranged in the water bath; and the upper end of the negative pressure tank is provided with a liquid adding port, the liquid adding port is provided with a tank cover, the bottom of the negative pressure tank is tapered in shape and is immersed in water in the water bath, the top of the tank cover is provided with an air discharging valve, one side of the tank cover is provided with an air exhaust hole, the bottom of the negative pressure tank is provided with a liquid discharging tube, the liquid discharging tube is provided with a first branch tube and a second branch tube, the first branch tube is used for discharging a concentrated liquid, the second branch tube is connected with the inlet end of an electric spray pump, the outlet end of the electric spray pump is connected with a jet tube, and the other end of the jet tube extends into the tank cover and is provided with a spray head. The apparatus has the advantages of continuous working, large throughput every time and high efficiency, and can completely meet liquid concentration and evaporation and solvent recovery requirements of general laboratories.

Description

technical field [0001] The invention relates to a liquid concentration evaporation device, in particular to a liquid concentration device. Background technique [0002] Concentrators are widely used in laboratories. For example, rotary evaporators are widely used in test occasions such as liquid concentration and solvent recovery. However, in some experiments, the sample processing volume is relatively large, and the processing volume and processing efficiency of the general rotary evaporator are small, which cannot meet the experimental requirements. [0003] The concentration of the solution and the evaporation and recovery of the solvent are mainly heated within a certain range to increase the internal energy of the liquid, so that the solvent molecules have higher molecular kinetic energy so as to escape the bondage of the surface tension of the liquid and volatilize. However, in order to protect some of the material components in the solution, it is impossible for us ...
