Abstract

The invention discloses a filter, which comprises: a filter body, which is embedded on a wall, and the filter body includes an air inlet box section, a primary filter box section, an aerosol injection section, The secondary filter box section and the air outlet box section, the aerosol injection section is equipped with a first aerosol dust-generating pipe for injecting aerosol particles; the air outlet box section is provided with an air outlet, and on the air outlet A sealing valve plate device is installed, and the sealing valve plate device is used to seal or open the air outlet; a filter element module is installed in the first-stage filter box section and the second-stage filter box section, and is used to compress the air outlet. The pressing mechanism of the filter element module and the point-by-point scanning leak detection mechanism located downstream of the filter element module, the point-by-point scanning leak detection mechanism is used to scan and detect the aerosol particles injected into the upstream of the filter element modules respectively. The filter has multiple functions, high safety level, double filtering function, and reliable airtightness.

Description

technical field

[0001] The present invention relates to the technical field of filtering equipment, in particular to a filter. Background technique

[0002] The filter is a box-type air purification negative pressure safety device that can prevent some dangerous or unknown biological particles from escaping aerosols during the experimental operation. It is widely used in scientific research, teaching, clinical inspection and production in the fields of microbiology, biomedicine, genetic engineering, biological products, etc. It is the most basic safety protection equipment in the first-level protective barrier of laboratory biosafety.

[0003] At present, the existing wall-mounted filter has a single function and only has a first-level filtration function, and cannot perform operations such as in-situ disinfection and air tightness detection on the filter, and there is a risk of leakage caused by improper installation. If it fails to meet the requirements, it cannot meet th...
