The sample thief include air inlet, gas outlet and be located the air inlet and the gas outlet between the aspiration pump, still including being located the trap between air inlet and the aspiration pump, the chamber is acceptd to the first second of acceping the chamber and being located the body opposite side that the trap includes the body, be located body one side, this internal filtration membrane that installs, the second is acceptd the chamber and is provided with a plurality of recesses, be provided with splendid attire filtration membrane's box in the recess. The utility model discloses a sample thief simple structure conveniently carries, and first accept the chamber and the chamber is acceptd to the second through setting up, can detect a plurality of samples in succession, need not to wait for, the dust that drops owing to preserve for a long time can be gone up by splendid attire filtration membrane to the box to the guarantee of weight is unchangeable, improves the degree of accuracy that detects.
Description
Technical field
The utility model relates to a kind of dust sampler, particularly relates to a kind of Portable mining dust sampler, belongs to environment and occupational health monitoring technical field.
Background technology
Dust refers to the aerial solia particle that suspends.Have many titles to dust traditionally, as dust, dust, flue dust, mine dust, sand dust, powder etc., these nouns do not have obvious boundary.ISO, the solid suspension that particle diameter is less than 75 μm is defined as dust.Dust too much or very few in air will produce disastrous effect to environment.But in live and work, industrial dust is the natural enemy of human health, it is the main cause of bringing out various diseases.
It is of poor quality that mine air quality compares atmospheric air, therefore needs various kinds of sensors to detect air quality, and wherein mining dust concentration detection sensor is then one wherein.When the detection of current mining dust concentration sensor adopts filter to touch meter heavy method, can not continuous coverage, and also very inconvenient when needing continuous test sample.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Portable mining dust sampler.
The utility model is achieved through the following technical solutions:
Portable mining dust sampler, comprise air intake opening, gas outlet and the aspiration pump between air intake opening and gas outlet, also comprise the drip catcher between air intake opening and aspiration pump, described drip catcher comprises body, be positioned at the first host cavity of body side and be positioned at the second host cavity of body opposite side, in described body, filtering membrane is installed, described second host cavity is provided with multiple groove, is provided with the box of splendid attire filtering membrane in described groove.
Described Portable mining dust sampler, described body interior is provided with the draw-in groove of engaging filtering membrane.
Described Portable mining dust sampler, described body has outlet, and described outlet can be closed by an openable door, and the center line of described outlet overlaps with draw-in groove center line.
Described Portable mining dust sampler, is provided with multiple dividing plate in described first container cavity.
Described Portable mining dust sampler, described first host cavity is connected with body with the second host cavity is dismountable.
Described Portable mining dust sampler, is also provided with flowmeter between described drip catcher and aspiration pump.
The beneficial effect that the utility model reaches:
Sampler structure of the present utility model is simple, is convenient for carrying, by arranging the first host cavity and the second host cavity, can the multiple sample of continuous detecting, without the need to waiting for; The dust that box can splendid attire filtering membrane drop owing to preserving for a long time, thus ensure that weight is constant, improve the accuracy detected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of the utility model drip catcher.
In figure: 1, air intake opening, 2, gas outlet, 3, aspiration pump, 4, drip catcher, 41, body, the 42, first host cavity, the 43, second host cavity, 5, filtering membrane, 6, groove, 7, box, 8, draw-in groove, 10, door, 11, dividing plate, 12, flowmeter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in the figure, Portable mining dust sampler of the present utility model, comprise air intake opening 1, gas outlet 2 and the aspiration pump between air intake opening 1 and gas outlet 23, also comprise the drip catcher 4 between air intake opening 1 and aspiration pump 3, described drip catcher 4 comprises body 41, be positioned at the first host cavity 42 of body 41 side and be positioned at the second host cavity 43 of body 41 opposite side, in described body, 41 are provided with filtering membrane 5, described second host cavity 43 is provided with multiple groove 6, is provided with the box 7 of splendid attire filtering membrane 5 in described groove 6.
Described body 41 inside is provided with the draw-in groove 8 of engaging filtering membrane 5.Described body 41 has outlet, and described outlet can be closed by an openable door 10, and the center line of described outlet overlaps with draw-in groove 8 center line.Multiple dividing plate 11 is provided with in described first container cavity 42.Described first host cavity 42 is connected with body 41 with the second host cavity 43 is dismountable.Flowmeter 12 is also provided with between described drip catcher 4 and aspiration pump 3.
Draw-in groove 8 can engage filtering membrane 6, ensures filtering membrane 6 stablizing in body 1; Outlet can be used to pick and place filtering membrane 5 easily; First container cavity is divided into multiple compartment by multiple dividing plate 11, can holding multiple pieces filtering membrane 5, and every block filtering membrane 5 can separately be deposited; First host cavity 42 is connected with body 41 with the second host cavity 43 is dismountable, under the state not needing the first host cavity 42 and the second host cavity 43, they can be taken off.Flowmeter 12 directly can demonstrate the apparent value flow of sampling thief.
Portable mining dust sampler of the present utility model in use, before detection, box 7 is weighed, record data, untapped filtering membrane 5 is placed in the first host cavity 42, during detection, filtering membrane 5 is mounted in body 41, aspiration pump 3 works, air enters drip catcher 4 from air intake opening 1, then go out from gas outlet 2, and the dust in air is filtered film 5 tackles, stay on filtering membrane 5, after detection completes, take out filtering membrane 5, be placed in box 7, be placed in the second host cavity 43, can detect next time, after treating that all check points detect, disposable box 7 to be taken out, weigh successively, front and back weight subtracts each other the amount that can obtain increasing weight, by air mass flow and sampling time, the concentration of contained dust in collected air can be calculated.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
