Dust detection device

Abstract

The invention relates to the field of detection and in particular discloses a dust detection device. The dust detection device comprises a rack, a detection mechanism and a cleaning mechanism, whereinthe detection mechanism comprises an air homogenization machine, an air inlet channel, an air outlet channel, a detection filtering screen and a switching assembly; the air inlet channel is obliquelyarranged; the switching assembly comprises a baffle plate and a switch; a torsion spring is arranged between the baffle plate and an inner wall of the air outlet channel; the baffle plate can press the switch; the cleaning mechanism comprises an air pump, a water storage tank, a water groove and a cleaning pipe; when the switch is pressed, the air pump is powered off; an air outlet pipe is fixedat an air outlet end of the air pump; the air outlet pipe is communicated with the water storage tank; the cleaning pipe is internally provided with a cleaning spring and a sliding block; two ends ofthe cleaning spring are fixed on the sliding block and the inner wall of the cleaning pipe respectively; the water groove is located below one end, far away from a draught fan, of the air inlet channel. The dust detection device provided by the invention can be used for automatically cleaning deposited dust.

Description

technical field [0001] The invention relates to the field of detection, in particular to the field of dust detection. Background technique [0002] During the production process of the factory, due to cutting, crushing and other processes, there will often be a large amount of dust in the workshop. The dust falling on the equipment will easily cause short-circuit damage to the equipment, and it will also cause damage to the health of the workers after being inhaled by the workers. Therefore, in the factory It is necessary to install a dust detection device to detect the dust in the air of the workshop. When there is too much dust in the air of the workshop, it is necessary to evacuate the workers and clean up the dust in the air. [0003] Current dust detection devices usually use the principle of light scattering to irradiate air particles with laser or infrared rays, collect reflected light signals, and use statistical principles to calculate the number or concentration of...

AI Technical Summary

Problems solved by technology

Although this detection device has high detection accuracy, it needs to introduce the air containing particles into the air flow channel through the blower, and more dust is easily deposited in the air flow channel, which eventually reduces the accuracy of the dust sensor and shortens the service life of the detection device
