Convenient-to-mount mine dust sampler

Abstract

The invention discloses a convenient-to-mount mine dust sampler, which comprises a shell, an air let, an air outlet and a suction pump, the air inlet is arranged on the side of the shell, the air outlet is arranged on the side, which is far from the air inlet, of the shell, the suction pump is arranged inside the shell, the suction pump is arranged between the air inlet and the air outlet, and a collector is arranged between the air inlet and the suction pump. The convenient-to-mount mine dust sampler further comprises a cleaning tube, a filter membrane is arranged inside the collecting orifice of the cleaning tube, a cleaning pump is connected to the cleaning tube, a blowing tube is connected to the cleaning pump, and the blowing tube is connected to the collector. The convenient-to-mountmine dust sampler further comprises supporting rods, a bearing plate and a turning shaft, one end, which is far from the bearing plate, of the turning shaft is provided with a fastener, and the fastener is connected to the lower surface of the shell. Wind is blown into the collector via the blowing tube to clean off dust remaining in the collector; and the convenient-to-mount mine dust sampler can be rapidly adjusted in a vertical direction and a horizontal direction.

Description

technical field [0001] The invention relates to a mine dust sampler, in particular to a mine dust sampler which is easy to install. Background technique [0002] Dust refers to solid particles suspended in the air. It is customary to have many names for dust, such as 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. The presence of dust in the atmosphere is one of the main reasons for maintaining the temperature of the earth. Too much or too little dust in the atmosphere will have a catastrophic effect on the environment. But in life and work, productive dust is the natural enemy of human health and the main cause of various diseases. [0003] Dust sampler refers to a portable device for collecting dust samples in dusty air. It is widely used in health monitoring and evaluation of dise...

Problems solved by technology

[0005] The invention solves the problem that the mine dust sampler in the prior art will have residual dust in the collector after the work is completed, which is not conducive to the next collection work of the mine dust sampler and affects the detection of dust concentration; the mine dust sampler It is inconvenient to adjust the collection location and collection orientation during use. The height of the mine dust sampler from the ground is too low during use. Due to environmental reasons, sludge enters the mine dust sampler and affects the detection of dust concentration. To solve the problem of accuracy, we provide a mine dust sampler that is easy to install. When it is used, it can clean the collector of the mine dust sampler, so that the collector is always in a clean state, ensuring that the next time the mine dust sampler is used The accuracy of the measured data; it can be adjusted in the vertical and horizontal directions without moving the mine dust sampler, which is convenient for the staff to operate
