Clean bench capable of monitoring leakage in real time

Abstract

The invention relates to a clean bench capable of monitoring leakage in real time. The clean bench comprises a box body, a detection structure, a movement unit and a scanning probe, wherein the box body is of a structure with an opening in one side, and a working area is formed inside the box body; the detection structure is arranged in the box body and is positioned at the upper part of the working area; the detection structure comprises a scanning movement platform which is arranged in the box body and is positioned at the upper part of the working area; the movement unit is arranged in the scanning movement platform; and the scanning probe is arranged on the movement unit. According to the clean bench capable of monitoring the leakage in real time, the detection structure is arranged in the working area, the probe for detecting the cleanliness is fixed on one movement track in the detection structure and can move in the track, the probe for detecting the cleanliness can gradually scan along the track when the clean bench is in actual use and the leakage detection is realized; when the leakage occurs, a signal can be output in real time, and equipment can give a sound-light alarm signal timely to prompt operating personnel to check and maintain timely.

Description

technical field [0001] The invention mainly relates to the field of biological safety purification, in particular to a clean workbench for real-time monitoring of leakage. Background technique [0002] Clean benches are widely used in medical, pharmaceutical, food, electronics, instrumentation, and bioengineering industries. The purpose is to provide a local sterile and dust-free space to prevent external microbial contamination. The clean workbench is powered by a motor, and the air is blown out through a high-efficiency filter to form a continuous laminar flow of dust-free and sterile ultra-clean air, the so-called "high-efficiency clean air", which removes more than 0.3 μm or even 0.12μm dust, fungi and bacterial spores, etc. The flow rate of the ultra-clean air is enough to prevent the pollution caused by the possible disturbance of the nearby air. The staff operates under such sterile conditions to keep the sterile materials free from contamination during the transfer ...

AI Technical Summary

Problems solved by technology

Traditional clean benches can only be inspected during the initial installation, and the integrity of the filter cannot be guaranteed during subsequent use

If leakage occurs, it will not be able to provide a safe and clean environment for the sample, and there will be safety risks in continued use, and the clean area of ​​the working area may be polluted by the outside air so that it loses the role of a clean bench
