Title:
ROTARY EVAPORATOR CAPABLE OF AUTOMATICALLY CONTROLLING CONTINUOUS FEEDING AND DISCHARGING
Document Type and Number:
WIPO Patent Application WO/2019/153679
Kind Code:
A1
Abstract:
Disclosed is a rotary evaporator capable of automatically controlling continuous feeding and discharging, comprising a bracket (1), wherein a detachable distilling flask (2) and a condenser (3) are fixed to the bracket (1), a receiving flask (4) is connected to the bottom of the condenser (3), a ventilation channel (5) is formed inside the condenser (3), the ventilation channel (5) is in communication with the distilling flask (2) and forms a ventilation tube (6) at a side wall of the condenser (3), and a ventilation valve (7) is provided at an atmosphere entry (30) of the ventilation tube (6) to control the communication of the interior of a distilling system with the atmosphere; the ventilation channel (5) is further internally provided with a feeding channel (8) and a discharging channel (9), and the feeding channel (8) and the discharging channel (9) are in respective communication with a feeding port (10) and a discharging port (11) formed at the ventilation tube (6) and are controlled by a feeding valve (12) and a discharging valve (13); and the feeding port (10) and the discharging port (11) are each connected to a power device, thereby realizing automatic feeding and discharging during the use of the rotary evaporator, and avoiding frequent manual operations.
