Full-automatic dust generating device

Abstract

The invention provides a full-automatic dust generating device which is characterized in that a hopper is mounted on a rack, and an electromechanical control box and a feeding mechanism are mounted inthe rack; the hopper is filled with powder, and a stirring material level sensing mechanism and a gate plate mechanism are arranged between the hopper and the feeding mechanism. The stirring materiallevel sensing mechanism is installed at the bottom of the hopper and used for scattering powder in the hopper and detecting the height of the material level of the powder in the hopper, and the stirring material level sensing mechanism scatters the powder so that the powder can enter the feeding mechanism conveniently. The flashboard mechanism is arranged below the stirring material level sensingmechanism and is used for adjusting the opening degree of the flashboard according to the dust generation concentration condition of the device, so that full-automatic dust generation is realized, the operation is simple and convenient, the labor intensity is reduced, remote control is realized, the experiment difficulty in a polluted environment is avoided, and the body health of workers is guaranteed.

Description

technical field [0001] The invention relates to the field of safety and environmental protection tests, in particular to a fully automatic dust generating device for simulating a dust environment. Background technique [0002] The hazards of dust are obvious to all, and one of its faults is to pollute the atmosphere and endanger human health. Dust floating in the atmosphere often contains many toxic components, such as chromium, manganese, cadmium, lead, mercury, arsenic and so on. When the human body inhales dust, particles smaller than 5 μm can easily penetrate into the lungs, causing toxic pneumonia or silicosis, and sometimes lung cancer. Once the pollutants deposited in the lungs are dissolved, they will directly invade the blood, causing blood poisoning, and the undissolved pollutants may also be absorbed by the cells, resulting in the destruction of the cell structure. [0003] In addition, the dust can contaminate buildings and corrode valuable ancient structures. ...

AI Technical Summary

Problems solved by technology

The original dust generator has a single type of dust, the dust concentration is not easy to adjust and control, and the continuous dust generation time is short. Frequent input of samples is required. Manual operation is required on the dust generation device to adjust the dust generation concentration or switch feeding. Under the action, the experimental environment around the device is often polluted by dust. Due to the unsafe working environment on site, it is not suitable for long-term on-site experiments. The on-site operation will affect the health of the staff. People need a remote automatic control dust generating device
