Description

TECHNICAL FIELD

[0001] The utility model provides a kind of compatible four sides visual and automatic response open and close multi-position vacuum concentration device, belong to vacuum concentration device technical field. BACKGROUND

[0002] Concentration is a commonly used sample pretreatment technique, and vacuum parallel concentration instrument is a widely used concentration pretreatment equipment. It can concentrate large volume samples in large quantities at the same time, and can completely replace multi-position rotary evaporator. Therefore, vacuum parallel concentration instrument is increasingly popular. Its principle is to reduce the pressure of the environment at a constant temperature to make liquid substances reach boiling point to evaporate, and then convert the steam into liquid by condensation to realize the concentration process. The concentration rate of vacuum parallel concentration instrument is related to water bath temperature, vacuum degree, oscillation frequency and condensation temperature. Most vacuum parallel concentration instruments use water bath heating, are integrally sealed, and have fixed embedded control terminal design. The sample bottle is integrally sealed. The operation is simple and convenient when concentrating and taking out batch samples. Most of the integrally sealed designs are nut type manual tightening, which can ensure the effective sealing of batch sample bottles. The water bath part has a water bath observation window, which is mostly three-sided visible. The water bath oscillation structure requires stable oscillation, which affects the parallelism of batch sample concentration. It is the key design of the water bath structure of vacuum parallel concentration instrument.

[0003] At present, most vacuum parallel concentration instrument water baths use three-sided visible design, which can easily cause the observation line of the blocked side to be blocked, resulting in excessive concentration of the sample. The batch sample integrally sealed method is very convenient when concentrating and taking out the sample. However, when new samples need to be added or concentrated samples need to be taken out, the instrument must be depressurized, and then re-evacuated to restart the experiment. This process slows down the concentration progress and reduces the experimental efficiency. The steam grooves on the integrally sealed cover plate are interconnected, and the condensation and dripping of steam after the experiment is completed can easily cause cross contamination between different samples. At the same time, the sample bottle sealing and taking out require manual disassembly and tightening operation of the nut by the user, which is very inconvenient. The amplitude and speed of the water bath oscillation structure affect the parallelism of batch sample concentration. As a rotating structure that needs to be used for a long time, its stability and durability are the key to the service life of vacuum parallel concentration instrument. Especially when improving the batch processing capacity of the instrument, higher performance is required for the structure. UTILITY MODEL CONTENTS
