Abstract
The utility model relates to the field of environmental monitoring, in particular to a measuring device for filterable residues in atmospheric suspended matters. A filtration device for measuring the filterable residues in the atmospheric suspended matters comprises a filter, a vacuum pump and a filter flask, wherein the filter is provided with a plurality of sample bottles, a bottleneck of the filter flask is sealed by a plug, the lower side face of the filter flask is provided with an outlet, an outlet of the filter is connected with a pipeline which is inserted into the plug of the filter flask to enter into the filter flask, and the vacuum pump is communicated with an inner cavity of the filter flask through a connecting pipeline. Under the condition that the device is not disassembled, the filtration device can finish multiple filtration operation, and the operation time is greatly reduced.
Description
Technical field
The utility model relates to the environmental monitoring field, but relates in particular to the determinator of filtration residue in a kind of aerosol.
Background technology
But the assay method for the filtration residue of suspension in the atmosphere is: must be placed on and claim evaporate to dryness to the evaporating dish of constant weight filtering the back water sample in the mensuration of the residue filtered of 103 ℃ ~ 105 ℃ of oven dry, dry to constant weight at 103 ℃ ~ 105 ℃ then, the amount of increase is can filter residue.The operation of present suspension suction filtration device is carried out suction filtration by volume of water sample a 500 ~ 1000ml, water tank must be removed from the suction filtration device after analyzing three to four samples, can carry out the next round analysis so that filtered water in the jar poured out.This operation is consuming time, and the frequent dismounting of hold-up vessel influences the device sealing, causes suction filtration efficient to reduce, and shorten device lifetime.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, but filtration residue mensuration suction filtration device in a kind of aerosol is provided.Under the situation of the utility model without detaching device, can finish repeatedly the suction filtration operation, shorten the running time greatly.
For addressing the above problem, but filtration residue is measured and is used the suction filtration device in a kind of aerosol of the utility model, it comprises nutsch filter and the vacuum pump that a plurality of sample bottles are installed, it comprises that also a bottleneck has the bottle,suction of outlet with plug seal, lower side, described nutsch filter outlet is connected with an insertion bottle,suction stopper and enters the interior pipeline of bottle,suction, and described vacuum pump is communicated with the bottle,suction inner chamber by a connecting pipe.
But filtration residue is measured and is used the suction filtration device in the described aerosol, and the outlet of described bottle,suction lower side is provided with sealing-plug.
The negative pressure that the utility model utilizes suction filtration to produce all sucks the water in the suspension device in the water storage device, the waste water that suction filtration goes out enters in the special tap bottle, one dismountable sealing-plug is arranged at the tap bottle bottom, can discharge unnecessary waste water at any time, and need not dismantle single unit system.With relatively having the following advantages of prior art:
1. stock is the decaliter storage capacity, can bear the water yield of dozens of sample.
2. when reaching on the water storage in limited time, only need open the sealing-plug of bottom, just can carry out draining, need not to remove with the suction filtration device between be connected simple and feasible.
Description of drawings
Below, further specify the utility model in conjunction with the accompanying drawings:
Fig. 1 is a synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, but filtration residue is measured and is used the suction filtration device in a kind of aerosol, it comprises nutsch filter 1 and the vacuum pump 3 that a plurality of sample bottles are installed, it comprises that also a bottleneck has the bottle,suction 2 of outlet with plug seal, lower side, described nutsch filter 1 outlet is connected with insertion bottle,suction 2 stoppers and enters the interior pipeline 5 of bottle,suction, and described vacuum pump 3 is communicated with the bottle,suction inner chambers by a connecting pipe 6.
But filtration residue is measured and is used the suction filtration device in the described aerosol, and the outlet of described bottle,suction 2 lower side is provided with sealing-plug 4.
Claims (2)
1. but filtration residue is measured and is used the suction filtration device in the aerosol, it comprises nutsch filter and the vacuum pump that a plurality of sample bottles are installed, it is characterized in that, it comprises that also a bottleneck has the bottle,suction of outlet with plug seal, lower side, described nutsch filter outlet is connected with an insertion bottle,suction stopper and enters the interior pipeline of bottle,suction, and described vacuum pump is communicated with the bottle,suction inner chamber by a connecting pipe.
2. but filtration residue is measured and is used the suction filtration device in the aerosol according to claim 1, it is characterized in that the outlet of described bottle,suction lower side is provided with sealing-plug.
