Description
Technical field
The utility model relates to solvent dehydration purification devices.
Background technology
Laboratory chemistry organic synthesis research often need to be used highly purified anhydrous solvent, and its main method for making is to the aqueous solvent purification of dewatering.Existing dewatering has the heating way of distillation, desiccant dehydration method and membrane separation process.These methods have certain advantage, but also respectively have the shortcoming that cannot avoid.Such as the way of distillation easily causes fire and blast, desiccant dehydration method subsequent treatment is cumbersome, membrane separation process non-refractory, perishable.The device that adopts said method to make anhydrous solvent exists that cost is high, complicated operation and the low shortcoming of security.
Summary of the invention
The purpose of this utility model is to provide low, the simple to operate and safe high use for laboratory solvent dehydration purification devices of a kind of cost.
Technical solution of the present utility model is: it is by feed pipe, storage tank, blow-down pipe, platform balance, carrier pipe, measuring pump, tube connector, the first Filter column, filter post is taken over, the second Filter column, discharge nozzle, feed pipe ball valve and blow-down pipe ball valve form, feed pipe passes in storage tank downwards by the top of storage tank, and the mouth of pipe of feed pipe is positioned at tank bottom, blow-down pipe is connected to tank top, storage tank is positioned on platform balance, carrier pipe one end is connected on tank bottom sidewall, one end is connected on the input of measuring pump, tube connector one end is connected on the output of measuring pump, one end is connected on one end of the first Filter column, filter post is connected between the first Filter column and the second Filter column, the other end and the discharge nozzle of the second Filter column join, feed pipe ball valve and blow-down pipe ball valve are connected on respectively on feed pipe and blow-down pipe.Described the first Filter column is identical with the second Filter column structure, and it is comprised of housing, molecular sieve and filter screen, and molecular sieve and filter screen are positioned at housing, and filter screen is positioned at molecular sieve two ends.
Technology of the present utility model solves effect: low, the simple to operate and safe advantage of its tool cost.
