Description
Technical field
The utility model relates to a kind of powder concentration measurement device, particularly relates to a kind of portable powder concentration measurement device.
Background technology
Dust refers to the aerial solia particle that suspends, elegant dust is in an atmosphere often containing many toxic ingredients, as chromium and manganese, after human body sucks dust, toxic pneumonitis or silicosis can be caused, sometimes also can cause lung cancer, the collection of dust and monitoring are the piths of environmental protection, existing powder concentration measurement device is generally not easy to carry, and there is complicated operation and the inconvenient problem of maintenance, and not easily discharges due to the gas of external and internal pressure official post exhausr port.
Utility model content
The purpose of this utility model is just to provide a kind of portable powder concentration measurement device to solve the problem.
In order to achieve the above object, the utility model have employed following technical scheme:
A kind of portable powder concentration measurement device, comprise housing, collection head, filter membrane and exhausr port, the portable powder concentration measurement device of described one also comprises exsiccator, vasculum, pre-captured device, aspiration pump and flowmeter, described collection head is arranged on one end of described housing, described filter membrane and described exsiccator are all arranged in described housing, described filter membrane is arranged on described collection head side, the other end of described housing is connected with the seizure head of described pre-captured device, the tail end of described pre-captured device is connected with the flow collection end of described flowmeter by pipeline, described flowmeter and described aspiration pump are all arranged in described vasculum, described flowmeter is connected by the air entry of pipeline with described aspiration pump, the exhausr port of described aspiration pump is connected with pipeline, the outlet of described pipeline is arranged on the sidewall of described vasculum, said structure, makes the utility model be easy to carry, operates and overhaul.
Particularly, the outlet of described pipeline is provided with spiral case; Spiral case can ensure that the gas of exhausr port is discharged smoothly; The top of described vasculum is provided with handle; Described filter membrane is made up of vinyl chloride fibers.
The beneficial effects of the utility model are:
Flowmeter and aspiration pump are all arranged in a vasculum by the utility model, other devices are arranged on the side of vasculum, make the utility model by carrying vasculum, and take away the utility model, feature the utility model being had be easy to carry and overhaul, the utility model only need open pre-captured device and aspiration pump just can make the utility model start working, therefore the utility model has the feature of convenient operation, and the spiral case in the utility model can ensure that the gas of exhausr port is discharged smoothly.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of portable powder concentration measurement device of the utility model.
In figure: 1-collection head, 2-exsiccator, 3-handle, 4-vasculum, 5-exhausr port, 6-spiral case, 7-aspiration pump, 8-flowmeter, 9-pre-captured device, 10-filter membrane, 11-housing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of portable powder concentration measurement device of the utility model, comprise housing 11, collection head 4, filter membrane 10 and exhausr port 5, a kind of portable powder concentration measurement device also comprises exsiccator 2, vasculum 4, pre-captured device 9, aspiration pump 7 and flowmeter 8, collection head 4 is arranged on one end of housing 11, filter membrane 10 and exsiccator 2 are all arranged in housing 11, filter membrane 10 is arranged on collection head 4 side, the other end of housing 11 is connected with the seizure head of pre-captured device 9, the tail end of pre-captured device 9 is connected with the flow collection end of flowmeter 8 by pipeline, flowmeter and aspiration pump 7 are all arranged in vasculum 4, flowmeter 8 is connected by the air entry of pipeline with aspiration pump 7, the exhausr port 5 of aspiration pump 7 is connected with pipeline, the outlet of pipeline is arranged on the sidewall of vasculum 4, the outlet of pipeline is provided with spiral case 6, the top of vasculum 4 is provided with handle 3, filter membrane 10 is made up of vinyl chloride fibers.
The utility model principle is as follows:
During utility model works, by aspiration pump 7 air-breathing, the dust that swims making air heavy is worked as on filter membrane 10, again according to quality and the collection dust time used of dust on filter membrane 10, calculate the concentration of dust, exsiccator is used for dried dust, and reduce the final error measuring structure, dust concentration calculates formula: C=(W
2-W
1)/Qt wherein, C: dust concentration; W
2: the quality of filter membrane after sampling; W
1: the quality of sampling front filter; T: sampling time.
