Problems solved by technology
However, in the actual receiving process, because the temperature of the inner wall at the bottom of the condenser is affected by the external ambient temperature, it is higher than the actual temperature in the condenser, so the liquefied organic solvent may be volatilized again, thereby damaging the freeze-drying system

Embodiment Construction
[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] see Figure 1 to Figure 3 , the present invention is an organic solvent receiving device for a condenser of a lyophilizer, the condenser includes a drum-shaped casing 5 arranged horizontally, and a drain pipe 6 is provided at the lowest front end of the casing 5, The receiving device includes a receiving tray 1 arranged in the lower part of the housing 5 and two arcuate baffles 2 respectively arranged at the front and rear ends of the receiving tray 1, wherein,
[0017] The receiving tray 1 is an arc-shaped plate, and the outer surface of the receiving tray 1 is axially spaced with several pairs of arc-shaped reinforcing rings 3 distributed in axisymmetric form, so that the gap between the housing 5 and the receiving tray 1 The isolation distance is h, and h is 10mm, thus effectively ensuring the consistency of the temperature of the r...

The invention relates to an organic solvent receiving device used for a condenser of a freeze dryer. The condenser comprises a lying round barrel-shaped shell, wherein a drain pipe is arranged at the lowest position of the front end surface of the shell; the receiving device comprises a receiving disk arranged on the lower part in the shell and two arched baffles respectively arranged at the front and back ends of the receiving disk; the receiving disk is a cambered plate, a plurality of cambered reinforced rings which are distributed in an axisymmetrical mode are axially arranged on the outer surface of the receiving disk at intervals, and the isolation distance between the shell and the receiving disk is h; and the surface of the baffle at the front end of the receiving disk is provided with an outlet inserting in the drain pipe. By means of the organic solvent receiving device in the invention, the consistence of the temperature of the receiving device and the practical temperature can be effectively ensured, and the organic solvent collected in the receiving device is avoided from volatiliziing again, so that the solvent is more thoroughly recovered.
Description
technical field [0001] The invention relates to a pharmaceutical machine, in particular to an organic solvent receiving device for a freeze dryer condenser. Background technique [0002] Some freeze-dried products must use organic solvents as solvents, and during the freeze-drying process, organic solvents pose a great threat to the freeze-drying system and the environment, that is, organic solvents may also emulsify the vacuum pump while affecting the frosting of the cold trap. Oil and aged vacuum seals, thereby damaging the freeze-drying system. Therefore, in order to avoid the influence of the organic solvent, the organic solvent must be collected in the condenser. [0003] Under normal circumstances, the organic solvent volatilized from the product first liquefies into a liquid state in a specific environment, drips at the bottom of the condenser, and then flows into the organic solvent recovery device for recovery. However, in the actual receiving process, because the...
