Abstract
The utility model discloses a kind of pick-up unit of powder airborne dust.This device is by funnel, and funnel stand, powder splendid attire cup, airborne dust receiving vessel and non-airborne dust receiving vessel form.Funnel stand fixed funnel is at a certain fixing height and position, and airborne dust receiving vessel is contained in non-airborne dust receiving vessel, and funnel, airborne dust receiving vessel, non-airborne dust receiving vessel three center are point-blank; Funnel bottom is 350mm apart from non-airborne dust receiving vessel bottom vertical distance.The utility model device devises the hydrostatic column receiving non-airborne dust part and airborne dust part cleverly, is received the mass ratio of particle, indirectly reflect the ratio of airborne dust in test powder by test airborne dust part.This utility model apparatus structure is simple, cheap, easy to use, is suitable for very much the airborne dust content measuring of various powder body material.
Description
Technical field
The utility model relates to a kind of easy device of testing powder airborne dust.
Background technology
Along with the development of science and technology and the requirement of people to quality of the life more and more higher, the attention rate of people to living environment air quality is more and more higher.Industrial powder industry easily produces airborne dust in process of manufacture, part airborne dust is due to containing speciality chemical composition, to factory indoor air ambient, even larger impact is all produced on factory's ambient air environmental quality, this is for the employee living in factory, and the resident near factory will be a serious health threat.Along with the development of science and technology, scientists and engineers start to take various technological means to go to control airborne dust technology in industrial powder, as there has been special commercialized product in Germany for controlling the dustfall agent of dry powder and mortar, domestic also have document to adopt interpolation speciality chemical for silo grain depositing dust etc.Airborne dust content in air can be tested by PM2.5 tester very well, and in powder, how the data of airborne dust test, and but do not have the method for special instrument and standard to evaluate.If can invent a kind of easy powder airborne dust proving installation, and set up unified method of testing, the powder dustfall agent product for development of new has great directive significance.
Summary of the invention
For above problem, the utility model discloses a kind of pick-up unit of powder airborne dust.Main contents of the present utility model are as follows:
A pick-up unit for powder airborne dust, described device detects airborne dust content in powder according to weighing principle; Described device by funnel, funnel stand, powder splendid attire cup, airborne dust receiving vessel and non-airborne dust receiving vessel composition; Described funnel stand fixed funnel is at a certain fixing height and position, and airborne dust receiving vessel is contained in non-airborne dust receiving vessel, and funnel, airborne dust receiving vessel, non-airborne dust receiving vessel three center are point-blank; Funnel bottom is 350mm apart from non-airborne dust receiving vessel bottom vertical distance.
Preferably, described funnel specification is, inlet diameter is 80mm, outlet spout of funnel diameter 20mm, the long 25mm of mouth; Described funnel material can select glass, plastics or quality of rubber materials.
Preferably, described non-airborne dust receiving vessel and described airborne dust receiving vessel are cylindrical, and wherein non-airborne dust receiving vessel diameter is 115mm, is highly 80mm, and airborne dust receiving vessel diameter is 350mm, is highly 370mm; The material of described non-airborne dust receiving vessel and described airborne dust receiving vessel can select glass, plastics or quality of rubber materials.
Preferably, described funnel material is plastic material; The material of described non-airborne dust receiving vessel and described airborne dust receiving vessel is glass material.
Accompanying drawing explanation
The structural representation of the pick-up unit of a kind of powder airborne dust of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to instructions word to make those skilled in the art.
As shown in Figure 1, the utility model provides a kind of pick-up unit of powder airborne dust, comprising:
1 funnel, funnel inlet end diameter 80mm, endpiece diameter 20mm, endpiece length 25mm, funnel material is plastics;
2 funnel stands, support ring diameter is good between 30-60mm, fixed, or supporting seat fixes by iron stand;
3 powder splendid attire cups, specification does not limit, and be good with energy splendid attire 30-200g powder material gauge lattice;
4 airborne dust receiving vessels, diameter is 350mm, is highly 370mm, and material is glass;
5 non-airborne dust receiving vessels, diameter is 115mm, is highly 80mm, and material is glass;
Wherein, funnel stand fixed funnel is at a certain fixing height and position, and airborne dust receiving vessel is contained in non-airborne dust receiving vessel, and funnel, airborne dust receiving vessel, non-airborne dust receiving vessel three center are point-blank; Funnel bottom is 350mm apart from non-airborne dust receiving vessel bottom vertical distance.
In order to this covering device and using method thereof are more intuitively described, we adopt commercially available different plate cement A, B, C to carry out airborne dust test.Concrete testing procedure is: fix device, gets 50g cement, in 1 minute, pour funnel into powder splendid attire cup, and cement nature is flowed out from hopper outlet.Take the quality of cement in airborne dust receiving vessel and non-airborne dust receiving vessel, be designated as m1 and m2 respectively, calculate airborne dust content value w in powder according to formula w=m1/ (m1+m2) * 100%.Concrete data are as shown in the table:
The airborne dust data of table 1 three kinds of commercially available cement
By the data of above table 1, obviously can find out that the airborne dust content in three kinds of commercially available cement is followed successively by from small to large: C < B < A.By these data, enterprise in charge of construction is just targeted when selecting cement.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in instructions and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
