Biosafety cabinet provided with easily-assembled and disassembled filters

Abstract

The invention relates to a biosafety cabinet provided with easily-assembled and disassembled filters, belonging to the field of bioexperiment technology. The biosafety cabinet comprises an upper fan cover (2), a lower fan cover (4), the air exhaust filter (1) and the descending filter (5), wherein the upper fan cover (2) is fixedly connected with the lower fan cover (4); the air exhaust filter (1) is pressed at an air exhaust hole in the upper fan cover (2) by n air exhaust filter fixing rods; the descending filter (5) is pressed in the lower fan cover (4) by m descending filter fixing rods; and m and n are integers which are more than or equal to 2. According to the biosafety cabinet provided by the invention, the filters are very convenient to assemble and disassemble, so that maintenance personnel can work safely and reliably.

Description

technical field [0001] The invention relates to a biological safety cabinet with a filter that can be easily disassembled, in particular to a biological safety cabinet with an exhaust filter and a down filter that can be easily installed and disassembled, and belongs to the technical field of biological experiments. Background technique [0002] During the working process of the biological safety cabinet, it is necessary to protect the staff and experimental samples, which requires a complete air filtration system. Protection of staff: The work of the biological safety cabinet is divided into air inflow and exhaust. The air inflow is the environmental laboratory air that enters the cabinet through the glass door opening window, and the air that is discharged is the air circulated inside the biological safety cabinet, which is filtered through the exhaust air. The device filters out harmful substances and then discharges them to the environmental laboratory or outdoors. What ...

AI Technical Summary

Problems solved by technology

[0005] At present, the traditional biological safety cabinet has the following defects in the installation and disassembly: the filter is pressed by the screw pressure frame on the installation, which is troublesome to install, and the operating space of the wind hood is relatively small, which increases the difficulty of the installation work , which reduces the work efficiency; when replacing and disassembling the filter, it is first necessary to remove the front cover of the cabinet and the front cover of the windshield. Both the front cover of the cabinet and the front cover of the windshield have more fixing screws and are heavier. , need two maintenance personnel to cooperate to complete, it is time-consuming and laborious, and then disassemble the filter, because the filter installation adopts the method of screw pressure frame compression, and the operation space is relatively small, so it is difficult to disassemble and display. During the whole disassembly process, maintenance personnel are completely exposed to the front of the entire windshield, and there are a lot of harmful substances in the filter and windshield, which greatly increases the possibility of maintenance personnel being harmed
