Dust detection and purification device

Abstract

The invention belongs to the field of detectors, and specifically discloses a dust detection and purification device including a rack; the rack is rotatingly connected with an active roller and a driven roller; the active roller and the driven roller each have a shape of a circular truncated cone and have consistent size, and the active roller and the driven roller are reversely arranged; the driven roller is sleeved with a first convex block and a second convex block, and a belt for transmission is also arranged between the active roller and the driven roller; the belt is located between thefirst convex block and the second convex block, and a magnetic block is arranged on the belt; fiber filter cloth is arranged in a cavity of the active roller and located at one side, away from a piston rod, of a piston; the driven roller is provided with a through hole matched with a feed inlet and communicating with the cavity; the driven roller is provided with a through hole matched with a discharge inlet and communicating with the cavity; a detection unit is arranged in one side, close to a small-diameter end of the active roller, in the cavity of the active roller. With adopting of the dust detection and purification device, the requirement of timely purification after dust detection can be 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
