Embodiment Construction

[0079] A preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0080] refer to Figure 1 to Figure 3 , The present invention provides a filter, comprising: a filter body 1 embedded in a wall 2 . The front end of the filter body 1 is fully welded with a door frame 15, the door frame 15 has a baffle plate 1501 extending outwards around the four sides, and some adjustable fasteners 16 are installed on the left and right sides of the filter body 1. The piece 16 is located at the rear side of the wall body 2 . During installation, make the baffle plate 1501 of the door frame 15 lean against the front side of the body of wall 2, and clamp the both sides of the body of wall 2 by adjusting the fastener 16 to cooperate with the baffle plate 1501, so that the door frame 15 and the body of wall 2 can fit better ( Such as image 3 shown), to ensure the airtightness of the room.

Abstract

The invention discloses a filter which comprises a filter body embedded in a wall, the filter body comprises an air inlet box section, a first-stage filter box section, an aerosol injection section, a second-stage filter box section and an air outlet box section which are sequentially connected from bottom to top, and the aerosol injection section is provided with a first aerosol dust generating pipe used for injecting aerosol particles; the air outlet box section is provided with an air outlet, and a sealing valve plate device is installed on the air outlet and used for sealing or opening the air outlet; a filter element module, a pressing mechanism for pressing the filter element module and a point-by-point scanning leak detection mechanism positioned at the downstream of the filter element module are mounted in each of the first-stage filter box section and the second-stage filter box section; and the point-by-point scanning leak detection mechanism is used for performing point-by-point scanning detection on aerosol particles injected into the upstream of the respective filter element module. The filter has the advantages of multiple functions, high safety level, double filtering effect and reliable air tightness.

Description

technical field [0001] The 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 certain dangerous or unknown biological particles from aerosol dissipation during the experimental operation process. It is widely used in scientific research, teaching, clinical testing and production in the fields of microbiology, biomedicine, genetic engineering, and biological products. 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 filtering effect. It is impossible to perform operations such as in-situ disinfection and air-tightness testing on the filter, and there is still a risk of leakage caused by improper installation. Its safety level It does not meet the requir...
