Description
Technical field
The utility model relates to vacuum drying chamber, relates in particular to a kind of temperature-sensitive material to be concentrated crystallization and dry vacuum drying chamber.
Technical background
At present, finish for concentrating of solvent Rotary Evaporators commonly used in the laboratory, but after being concentrated to saturation state, solvent promptly have crystallization to occur, as continue to concentrate then crystallizing and drying fully, at this moment the crystallization of drag will all be taken out just very difficult, and solvent can not reclaim and absorb fully, and part can enter atmosphere by vavuum pump.If after nearly saturation state, be put into common vacuum drying chamber inner drying in solution concentration, can't release when a large amount of solvent vapo(u)rs in the drying box are another, the solvent of releasing can not fully reclaim and absorb again, thereby cause the waste of solvent and, also can cause infringement sometimes vavuum pump to the pollution of environment.
Summary of the invention
A purpose of the present utility model is to overcome above-mentioned deficiency, provides a kind of temperature-sensitive material concentrated crystallization and dry vacuum drying chamber.
The utility model is realized by following scheme: vacuum drying chamber is mainly by vacuum chamber, chamber door, vacuum breaker, vacuum meter and heated at constant temperature circuit, the vacuum switch valve, condenser for solvent, condenser pipe, solvent collection bottle, the molecular sieve absorber, vavuum pump is formed, and vacuum meter and heated at constant temperature circuit are installed on the vacuum chamber, open a chamber door on the vacuum chamber, vacuum breaker is installed in a side of vacuum chamber, the opposite side of vacuum chamber connects the vacuum switch valve, and the other end of vacuum switch valve is the entrance point that the port of export connects condenser for solvent, the built-in condenser pipe of condenser for solvent, the condenser for solvent below has a condensate liquid to collect a mouthful connection solvent collection bottle, the molecular sieve absorber is installed in bleeding of the port of export of condenser for solvent and vavuum pump between the end, be used to absorb remaining solvent vapo(u)r, connects with the vacuum rubber pipe between each port.
The molecular sieve absorber is detachable the installation.
The built-in condenser pipe of condenser is the sieve type, and condenser and condenser pipe are made by glass.
The vacuum drying chamber that the utility model provides has following characteristics: drying box is a door structure, can place the big mouthpart ware that fills solvent easily, and suitably heating, carries out vacuum drying, obtains crystallization.Behind the crystallizing and drying, owing to be big mouthpart ware, crystallization is taken out easily.A large amount of solvent vapo(u)rs both can be imported a certain amount of air by vacuum breaker in the vacuum chamber, also can import drying nitrogen, experiment is carried out under anaerobic condition, along with solvent vapo(u)r is constantly released by vavuum pump together, by condenser for solvent the time, because in the sieve type glass condenser pipe in the condenser for solvent mobile cooling liquid is arranged, solvent vapo(u)r promptly is condensed into liquid by steam, and in the solvent collection bottle below the inflow of taking advantage of a situation.The molecular sieve absorber can absorb remaining solvent vapo(u)r, and solvent vapo(u)r can not be entered in the atmosphere by vavuum pump.The utility model both can have been finished drying, crystallization, the recovery of solvent, can reach the purpose of protection atmospheric environment again.The utility model is suitable for teaching, scientific research, and medicine, chemical industry, food, fields such as environmental protection concentrate crystallization and drying to some temperature-sensitive materials.
