Embodiment Construction
[0025] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0026] refer to Figure 1 to Figure 3 As shown, the direct-reading dust measuring instrument of the present invention includes a rectangular housing 2, which is provided with a sampling device 12, an eddy current meter 3 whose model is AMW5140V, and a GJ6401αβγ end-window halogen G-M counter tube whose model is Quality testing device 5, electric air pump 9 of model 28YSK-6V, main board 16 and battery pack 10. Wherein, the sampling device 12 is fixedly installed on the upper part of the left side wall of the housing 2, and its sampling head 11 protrudes from the left side wall. The air inlet of the meter 3 is sealed and connected, and the air outlet of the vortex meter is sealed and connected with an elbow pipe 4, and the other end of the elbow pipe 4 is connected with the air inlet of the electric air pump 9 through a silicon rubber tube 7. The qua...

The invention discloses a direct reading dust gauge, which comprises a housing, and the inside of the housing is provided with a sampling device, a turbulence gauge and an electronic air pump which are connected in a sealed manner in sequence. The direct reading dust gauge also comprises a mass detecting device, a mainboard and a battery pack which are arranged inside the housing. When the direct reading dust gauge is used, the mass of blank filter membranes in a filter membrane nipper is measured by the mass detecting device, and then the filter membrane nipper is inserted into a sampling head; during sampling, the air containing dust flows through the sampling head, the sampling device, the turbulence gauge and the electronic air pump in sequence under the action of the negative pressure caused by the electronic air pump, and then is discharged from an outlet of the electronic air pump; the filter membrane on the filter membrane nipper gathers dust in the air containing dust, and the flow of the gas flowing through the turbulence gauge is calculated by the turbulence gauge; after sampling, the mass of the filter membrane after the dust is eliminated can be measured by inserting the filter membrane nipper into the mass detecting device; and finally, the data is processed by a CPU of the mainboard, and the concentration of the dust can be calculated. Thus, the concentration of dust can be measured accurately in time, and the direct reading dust gauge has the advantages of simple operation and higher efficiency.
Description
technical field [0001] The invention relates to a dust measuring instrument, in particular to a mine direct-reading dust measuring instrument. Background technique [0002] The current known dust measurement is composed of a dust sampler, an electric air pump, etc., wherein a filter membrane clip is placed in the sampling head of the dust sampler, and a filter membrane is clamped on the filter membrane clip. When sampling in mines, the electric air pump works to generate negative pressure to suck the dusty air into the dust sampler, forming a certain air flow movement, and the mobile dust is captured by the filter membrane, and then remove the filter membrane clip to remove the dust sampler. The dust filter membrane is taken to the mine and weighed with a balance. Finally, according to the dust mass on the filter membrane and the sampling volume of the dust sampler, the dust concentration is calculated by dividing the two. However, this dust sampler cannot measure the obtai...
