Pass box special for clean room of pharmaceutical factory

Abstract

The invention discloses a pass box special for a clean room of a pharmaceutical factory. The pass box comprises a box body, wherein a fan box body, an efficient filter, an air supply orifice plate and an article delivery cavity are arranged in the box body in sequence from the top down; the fan box body is used for accommodating a fans; the efficient filter is used for purifying air; the air supply orifice plate is used for transmitting airflows; the article delivery cavity is used for delivering articles; gas tight doors, which are used for picking and placing articles and can be locked by each other, are respectively arranged on two opposite outer side surfaces, corresponding to the article delivery cavity, on the box body; perspective double-layered windows are respectively arranged in the middles of the two gas tight doors; an air return passage is arranged between the outer side surface of the article delivery cavity and the inner side surface of the box body, wherein the outer side surface of the article delivery cavity is perpendicular to the gas tight doors; the upper end of the air return passage is communicated with the air inlet of the fan; an air return orifice plate is arranged below the side surface, corresponding to the air return passage, of the article delivery cavity, so as to enable the article delivery cavity to in airflow communication with the air return passage. According to the pass box, the structure of the airflow box body is more reasonable in design; online leak detection can be easily performed; the pressure difference of the efficient filter can be monitored in real time.

Description

technical field [0001] The invention relates to a special transfer window for the clean room of a pharmaceutical factory conforming to the new version of GMP, which is mainly used for transferring articles between the clean area and the non-clean area of ​​the production workshop of the pharmaceutical manufacturing enterprise. Background technique [0002] There are many shortcomings in the transfer window used in the medical clean room in the existing market, mainly as follows: 1. The airflow of the shower items in the box may have turbulent flow, which cannot take away the particles that may exist on the surface of the object or cause the box to The body cannot reach Class 100 cleanliness, which does not meet the requirements of GMP; 2. The high-efficiency filter cannot perform effective on-site leak detection, and the aerosol detection device and structure are not designed, which does not meet the requirements of GMP; 3. There is no design for differential pressure detecti...
