Abstract

The utility model relates to a new type rotary evaporator, which comprises an electric motor, a condensation tube, an evaporation bottle, a receiving bottle and a bear frame. The utility model is characterized in that the electric motor and a rotary mechanism connected between the condensation tube and the evaporation bottle are separated structures, and the connection way of the transmission shaft of the electric motor and the rotary mechanism is a dischargeable transmission locking type connection. An air heating device is arranged in the evaporation bottle.

Description

A kind of novel rotary evaporator
Technical field
The utility model relates to a kind of rotary evaporator, this evaporimeter pulls into liquid film with liquid after making the container rotation by transmission device, be heated and the state of negative pressure under evaporation rapidly, through behind the condenser pipe again condensation get off, thereby reach concentrated product, reclaim purposes such as solvent.Be widely used in fields such as food, biology, medicine, chemical industry.
Background technology
At present, known Rotary Evaporators structure is to be combined by support, motor, speed regulator, the rotatable portion of band sealing ring, condenser pipe, receiving bottle.The flask that will fill the article that need to concentrate during use connects thereon, need adjust highly to make it suitable with the liquid level position in the water-bath, opens water pump and condensed water, adjusting rotating speed and water temperature.Its structure more complicated, cost of manufacture is very high, because motor and rotary part connect as one, so just be difficult to maintenance and replacing in case long-time use back motor is damaged, severe patient causes scrapping of whole instrument.The more important thing is that existing Rotary Evaporators all wants the hydrous water bath to use, certainly high-grade product water-bath is the part of himself, so just some problems have inevitably been brought: at first, to regulate the relative altitude of liquid level during use, the way that solves is to regulate the height of water-bath or the height of rotating mechanism, the former generally is to use the water-bath of adjustment height to realize, and the latter generally improves in the design of support, adopt electric up-down as expensive goods, but these improvement all fail fundamentally to address this problem, and the liquid of water-bath heats up needs the long time, secondly, can't be warming up to more than 100 ℃, though can adopt oil bath to bring inconvenience to use, and operate miss, or contingency all easily causes revolving bottle to fall into the water as having a power failure etc.
The utility model content
The technical problems to be solved in the utility model is how a kind of novel rotary evaporator is provided, and this evaporimeter can overcome above-mentioned shortcoming, and simple in structure, operation, easy to maintenance, and highly versatile, production cost is low.
The technical problem that proposes of the present utility model is to solve like this: a kind of novel rotary evaporator is provided, comprises motor, condenser pipe, evaporative flask, receiving bottle and support, it is characterized in that:
A. described motor and be connected condenser pipe and evaporative flask between rotating mechanism be split-type structural, the power transmission shaft of described motor and the connected mode of rotating mechanism are detachable transmission clamping;
B. described evaporative flask is provided with gas-heating apparatus.
According to novel rotary evaporator provided by the utility model, it is characterized in that, described gas-heating apparatus is the hot air circulate heater, mainly constitute by cloche and box sealing, be provided with motor and fan in the end of casing, the inside of casing is provided with the hot-air transfer tube that is connected with fan.
According to novel rotary evaporator provided by the utility model, it is characterized in that, be provided with hot water radiation wire and attemperating unit in the described hot-air transfer tube, described attemperating unit comprises parts such as temperature measuring equipment and register, and described temperature measuring equipment can be a temperature sensor.
According to novel rotary evaporator provided by the utility model, it is characterized in that described gas-heating apparatus can be the blowing-type drying box.
According to novel rotary evaporator provided by the utility model, it is characterized in that, be provided with semicircle thin slice in the described evaporative flask, can enlarge the evaporation of liquid face, improve evaporation effect.
According to novel rotary evaporator provided by the utility model, it is characterized in that the junction of described receiving bottle and condenser pipe is provided with the wide tee valve, in use the installing/dismounting receiving bottle.
Novel rotary evaporator provided by the utility model has following advantage:
Since motor be connected condenser pipe and evaporative flask between rotating mechanism be split-type structural, when wherein a when damage part or when needing repairing, can not influence other parts, simple in structure, easy to maintenance;
2. owing to adopted special heater (changing gas-heating apparatus into), can avoid incidental problem in the prior art by liquid heating, and homogeneous heating, easy to operate.
