Problems solved by technology

Due to the uncertainty of the test bench and the test, the variety of experimental operations is caused. The common form of clean exhaust cannot collect and remove all the polluted air in a timely manner, causing personal safety hazards to the test personnel.
At present, the existing technical methods can meet the overall negative pressure and cleanliness requirements of the laboratory, but cannot meet the special cleanliness requirements of the local area, especially without the lifting function, and the polluted air caused by the experiment cannot be collected and purified in a timely manner and removed from the outside. Security risks

Abstract

The invention discloses a scanning type efficient purifying and return air collecting device, and relates to the technical field of air filters. According to the structure of the scanning type efficient purifying and return air collecting device, a biological safety valve is installed at the top of an air port box body, and a centrifugal fan is fixed to the bottom of the biological safety valve; the left side of a negative pressure meter monitor is provided with a pipeline A and a pipeline B, the pipeline A is connected with the centrifugal fan, and the pipeline B is connected with an air filter; the air filter is installed at an indoor scanning air port; a scanning mechanism conducts regular leakage detection on the air filter through a scanning driving motor; and an air collecting coveris installed on the periphery of the air filter through sealing pressing plates and subjected to height adjusting through an air collecting cover lifting mechanism. The scanning type efficient purifying and return air collecting device has the beneficial effects that scattering of infectious matter aerosol generated in the class A infectious germ freeze-drying experiment process is effectively reduced, the infection risk of experimenters in the freeze-drying process is reduced, the problem that experimenters cannot do infectious experiment activity in a biological safety cabinet is solved, andthe life safety of the experimenters is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to a scanning type high-efficiency purification return air collection device. Background technique [0002] When conducting high-level biological tests in biosafety laboratories and biochemical laboratories, it should be possible to set up a high-level safe high-efficiency filtration system at the test bench position, which meets the requirements of GB19489 "General Requirements for Laboratory Biosafety" that "should be able to in situ exhaust high-efficiency air filter for disinfection and leak detection" requirements. Due to the uncertainty of the test bench and the test, the experiment operation is diverse, and the common form of clean exhaust cannot collect and remove all the polluted air in a timely manner, causing personal safety hazards to the experimenters. At present, the existing technical methods can meet the overall negative pressure and cleanliness requirements of ...
