Dust detection and purification device

Abstract

The invention belongs to the field of detection equipment, and specifically discloses a dust detection and purification device, which includes a frame on which a driving roller and a driven roller are rotatably connected. It is set opposite to the driven roller; the driven roller is covered with a first bump and a second bump, and a belt for transmission is also provided between the driving roller and the driven roller, and the belt is located between the first bump and the second bump. There is a magnetic block between the bumps and on the belt; fiber filter cloth is provided in the cavity of the driving roller on the side of the piston away from the piston rod, and a filter cloth is provided on the driven roller to match the feed port and communicate with the cavity. A through hole, the driven roller is also provided with a through hole that matches the discharge port and communicates with the cavity; the cavity of the driving roller is provided with a detection unit on the side close to the small diameter end of the driving roller. By adopting the solution of the present invention, the requirement that the dust can be purified in time after the dust detection is completed is met.

Description

technical field [0001] The invention belongs to the field of detection instruments, and in particular relates to a dust detection and purification device. Background technique [0002] Dust refers to solid particles suspended in the air. Dust is also called dust, dust, smoke, mine dust, sand dust, powder, etc. These terms have no obvious boundaries. The International Organization for Standardization stipulates that suspended solids with a particle size of less than 75 μm are defined as dust. In life and work, productive dust is the natural enemy of human health and the main cause of various diseases. Among them, the dust formed related to the production process is called productive dust. [0003] When a new home is decorated, a lot of decoration dust will be produced. These decoration dusts are a kind of productive dust. Before moving to a new home, it is necessary to check whether the dust content in the home exceeds the standard. The dust detector in the prior art genera...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned device has the following problems: 1. In the case of a larger overall space and less dust, the refraction of light is weak, and the change of the light signal is small. It is likely that the alarm cannot be triggered, and the dust cannot be purified in time. When there are old people or children with weak resistance, even a small amount of dust is very harmful; 2. When there are people with disabilities at home, after the alarm is issued, it may not be possible to open the windows in time for ventilation. Purify the dust in time, and there is a lot of dust at this time, which may cause great harm
