The invention provides an isolating device adopting closed discharging. The isolating device comprises an operation cavity and a functional cavity fixedly connected with the operation cavity, a sealing door and a door frame are arranged in the operation cavity, the operation cavity is divided into a first cavity body and a second cavity body by the sealing door and the door frame, a first fan, a second fan and a controller are arranged in the functional cavity, a control switch of the first fan and a control switch of the second fan are both electrically connected with the controller, a firstair outlet pipe of the first fan communicates with the first cavity body, a second air outlet pipe of the second fan communicates with the second cavity body, a first filter is arranged in a first airinlet pipe of the first fan, a second filter is arranged in the first air outlet pipe of the first fan, a third filter is arranged in a second air inlet pipe of the second fan, and a fourth filter isarranged in a second air outlet pipe of the second fan. The air speed and the gas intake and exhaust amount of the first fan and the second fan are controlled through the controller to realize the change of the pressure difference of a box body so as to realize a suitable and stable gas pressure environment of the box body, and meanwhile a gas medium can be discharged differently according to different requirements to be suitable for different materials.
Description
technical field [0001] The invention belongs to the technical field of isolation boxes, in particular to an isolation device for airtight discharge. Background technique [0002] When current domestic raw material pharmaceutical factories are performing operations such as small-batch testing, experimentation, sub-packaging, weighing, crushing, freeze-drying or drying, etc., they often use fume hoods and operators wear special protective clothing to carry out part-time inspection of operators. Protection, its protective effect is poor and has great limitations on the performance of materials, such as lighter materials, strong odor, poisonous, and highly diffusive materials are very difficult to operate. [0003] In order to avoid the limitations of the existing protective fume hoods and protective clothing, the present invention adopts the form of a closed shell, and performs a series of corresponding operations on the materials through gloves. The system is used to control ...
