Description

Technical Field

[0001] The utility model belongs to the technical field of drying ovens, and particularly relates to an anti-backflow partition device for a drying oven. Background Art

[0002] A drying oven is an experimental device used for drying, curing, baking and other materials, and is widely used in industries such as chemical industry, electronic communication, plastics, cables, electroplating, hardware, automobiles, optoelectronics, rubber products, molds, spraying, printing, medical treatment, aerospace and institutions of higher learning. The anti-backflow partition device for a drying oven (especially a vacuum freeze dryer, hereinafter referred to as a freeze dryer) is a specially designed device, aiming to prevent the backflow phenomenon of the drain pipe caused by the pressure difference inside and outside the box during the processes such as cleaning and steam sterilization, that is, the water from the floor drain or other external water sources is sucked into the pipe and enters the drying oven. The principle of this device is mainly based on the control of air pressure and fluid mechanics to ensure that water does not flow back into the drying oven when the pressure changes. Usually, a special anti-backflow partition device is equipped for a vacuum freeze dryer (freeze dryer) to cope with the backflow phenomenon caused by the pressure difference inside and outside the box during the processes such as cleaning and steam sterilization.
