Dismountable semi-automatic water-bath vibrating evaporating device

Abstract

The invention discloses a dismountable semi-automatic water-bath vibrating evaporating device. The device comprises a support and a storing bottle, wherein the storing bottle comprises a connecting end and an air outlet end; a cross bar is arranged at the upper end of the support; a thick spring is arranged on the cross bar; one free end of the thick spring is connected to the cross bar while theother end of the thick spring is fixedly connected to a vibrating part; a vibrating motor is arranged in the vibrating part and is provided with a rate regulating switch. With the adoption of the device, an evaporating bottle can be automatically vibrated during experiment, and the motor rate adjustment fits the spring elasticity adjustment, so that the vibrating frequency and amplitude comprehensive adjustment of the vibrating bottle is realized; an experiment product in the storing bottle is driven to vibrated at different degrees, thus the heating area and the evaporating area of the experiment product are increased, and the evaporating efficiency is improved; and the dismountable storing bottle is easily conveniently washed after experiment.

Description

technical field [0001] The invention relates to a detachable semi-automatic water bath vibration evaporator. Background technique [0002] The evaporator is an ideal necessary basic instrument for the physical and chemical industry, the pharmaceutical research and development industry, colleges and universities and scientific research laboratories for the concentration, drying and recovery of the manufacturing and analysis experiments. It puts the liquid or solid in the evaporating flask, fixes it with a bracket, and directly heats it in a water bath to achieve the purposes of concentration, drying, extraction, and recovery. Current evaporators all adopt rotary evaporators, and the rotating mechanism drives the evaporating flask (flask) to rotate to achieve uniform heating. The principle is to heat at a constant temperature under vacuum conditions to make the rotary bottle rotate at a constant speed, and the material forms a large-area film on the bottle wall and evaporates...

AI Technical Summary

Problems solved by technology

[0004] 1. When the evaporating bottle rotates, the liquid in the evaporating bottle will not rotate with the evaporating bottle under the action of gravity. Only a layer of liquid in contact with the bottle body can be adsorbed on the inner wall of the evaporating bottle. Therefore, even if the evaporating bottle rotates, large Part of the liquid remains at the bottom of the evaporating flask, which cannot make the liquid flow, resulting in low evaporation efficiency and long heating time

[0005] The liquid in the evaporating flask has a fixed contact surface with the heating source, and the liquid in the evaporating flask will not circulate, so that only the edge of the evaporating flask is fully heated from the beginning to the end, so that only a small part of the liquid can reach a certain temperature. Evaporation effect, while the rest of the experimental products can only get more heat after the edge part evaporates or the heat is transferred to other parts of the experimental product. Such a heating mode makes the evaporation efficiency of the experimental product not high, and the heating time also greatly lengthened

[0006] 2. The current evaporating flask has only one mouth. When cleaning the evaporating flask after the experiment is completed, the cleaning solution can only be poured into the evaporating flask again and again, and rinsed repeatedly. The evaporated and dried substances need to be soaked for a long time to be rinsed , causing a lot of inconvenience and wasting time

[0007] In the actual experiment process, if rapid heating and evaporation are required, the existing evaporating flasks cannot achieve good results, and the evaporating flasks can only be slightly shaken by manual assistance, so that the liquid can get more contact parts and increase the temperature. Evaporation efficiency, but this will cause a certain waste of personnel and time, and there are certain safety risks
