Dust capturing device

Abstract

The invention discloses a dust capturing device, relating to air detection equipment. The dust capturing device comprises a shell, a cylinder and a motor, wherein a cavity and only one upper opening are formed in the shell, a plurality of wind holes are formed in the bottom of the shell, a plurality of side holes are formed in the side wall of the shell, and a plurality of heating plates are further arranged in the shell; a plurality of small holes are formed in the bottom of the cylinder, and a filter net is distributed on the inner wall of the cylinder; and the motor is fixed in the cavity in the shell, a main gear is connected to an output end of the motor, the cylinder is sleeved with an auxiliary gear, the cylinder is mounted on the inner wall of the shell through a rotating shaft, and the main gear and the auxiliary gear are mutually meshed. The motor is started to drive the cylinder to rotate around the rotating shaft, and then the dust falling to the bottom of the cylinder is thrown to the side wall of the cylinder through a centrifugal force, so that the filter net at the bottom of the cylinder is unlikely to be blocked; and meanwhile, the heating plate is started to heata space in the shell, air and dust which enter the cylinder are heated during the rotation of the cylinder, moisture in the air and the dust are evaporated into water vapor, and the water vapor is thrown out of the cylinder through the side holes.

Description

technical field [0001] The invention relates to air detection equipment, in particular to a device for collecting dust. Background technique [0002] Dust sampler refers to a portable device for collecting dust samples in dusty air. It is widely used in disease prevention, environmental monitoring, labor protection, safety supervision, military, scientific research and teaching, metallurgy, petrochemical, railway, building materials and other departments. Hygienic monitoring and evaluation, specially used to determine the average concentration of dust in the air in the workplace of production teams. In the dust sampler, the pre-collector is a separation device of the dust sampler, which is used to collect dust and conduct relevant data analysis on the dust collected through the internal filter of the pre-collector. However, during the working process of the pre-collector in the current dust sampler, the dust collected by the filter screen in the pre-collector is easy to acc...

AI Technical Summary

Problems solved by technology

However, during the working process of the pre-collector in the current dust sampler, the dust collected by the filter screen in the pre-collector is easy to accumulate on the filter screen, which will cause the filter screen to be blocked. Drying is required, and the drying process will increase the overall man-hour
