Description

Surrounding air sampler

Technical field

The utility model is related to a kind of surrounding air samplers.

Background technology

At present, general gas flow sampling apparatus is sampled using SUMMA tanks or gas sampling bag.Such as Gas sampling SUMMA tanks disclosed in US5691487 are after being first pumped into negative pressure inside it, to be placed in sampled point, unscrew switch, profit Gaseous sample is collected in tank with its internal negative pressure.Gaseous sample sample mode is straight by pumping disclosed in US0269350 Connect acquisition air.

Above-mentioned gas sampling apparatus has as follows not when volatile organic contaminant is analyzed in gathering surrounding air Foot：Soviet Union's agate tank is generally used for the acquisition of light concentration gas, because its Bottle structure is spherical flat and with vacuum pressure valve, institute Cause sample copy bottom higher with not easy cleaning, next sampled measurements can be given to cause error.Gas sampling bag be usually it is square, Since square bag dead volume is big, every time after experiment, residual gas is difficult to empty completely in bag, and measurement result is caused to be deposited with actual value In deviation.

The content of the invention

It is easy to use and carry the technical problem to be solved by the utility model is to provide a kind of simple in structure, it is economical into This is low, easy to clean, the surrounding air sampler that the ambient air conditions gathered are stablized.

The utility model is achieved through the following technical solutions：A kind of surrounding air sampler, including tube body, is opened Pass, accumulator and motor, the tube body upper and lower side are open, and a pipe, pipe are threadedly coupled in the opening of tube body upper and lower side Upper and lower side is open, and pipe one end may be contained within the external world, and pipe is equipped with more than one on outer ring face one section extraneous Through hole, the through hole positioned at upper end are air admission hole, and the through hole positioned at lower end is gas vent, and pipe is located at fixed in extraneous opening The cover board of one sealed opening is installed, the diameter of cover board is identical with the diameter of tube body.

Preferably, a fixed block is fixedly mounted on the bottom surface of upper end cover board, the rounded structure setting of fixed block, Gu Determine in block lower end insertion pipe, the bottom surface of fixed block is equipped with an accumulator mounting groove, and the opening of accumulator mounting groove is equipped with The sealing cover of one opening or sealed cell mounting groove, accumulator are installed in accumulator mounting groove, and motor is fixedly installed in On the bottom surface of sealing cover, the shaft of motor is vertically set, and a fan is fixedly mounted, and switch is fixedly installed in upper end cover board Surface on, connected between switch, accumulator and motor by electric wire.

Preferably, being equipped with a circular hole positioned at the centre of lower end cover board, the rubber of a sealing circular hole is fixedly mounted in circular hole Layer.

Preferably, tube body, pipe and cover board are made of metal material.

The beneficial effects of the utility model are：The utility model is simple in structure, easy to use and carry, and financial cost is low, Easy to clean, the ambient air conditions gathered are stablized.

Description of the drawings

Fig. 1 is the overall structure diagram of the utility model.

Coding is respectively in figure：1 is rubber layer, and 2 be cover board, and 3 be gas vent, and 4 be pipe, and 5 be tube body, and 6 be air admission hole, 8 be fixed block, and 9 be switch, and 10 be accumulator mounting groove, and 11 be accumulator, and 12 be sealing cover, and 13 be motor, and 14 be fan.

Specific embodiment

As shown in Figure 1, this surrounding air sampler, including tube body 5, switch 9, accumulator 11 and motor 13, the pipe 5 upper and lower side of body is open, and a pipe 4 is threadedly coupled in the opening of 5 upper and lower side of tube body, and 4 upper and lower side of pipe is open, pipe 4 One end may be contained within the external world, and pipe 4, which is located on outer ring face one section extraneous, is equipped with more than one through hole, positioned at the logical of upper end Hole is air admission hole 6, and the through hole positioned at lower end is gas vent 3, and pipe 4, which is located in extraneous opening, is fixedly mounted a sealed opening Cover board 2, the diameter of cover board 2 is identical with the diameter of tube body 5.

A fixed block 8,8 rounded structure setting of fixed block, fixed block 8 are fixedly mounted on the bottom surface of upper end cover board 2 In lower end insertion pipe 4, the bottom surface of fixed block 8 is equipped with an accumulator mounting groove 10, is set in the opening of accumulator mounting groove 10 There is the sealing cover 12 of an opening or sealed cell mounting groove 10, accumulator 11 is installed in accumulator mounting groove 10, motor 13 are fixedly installed on the bottom surface of sealing cover 12, and the shaft of motor 13 is vertically set, and a fan 14 is fixedly mounted, switch 9 are fixedly installed on the surface of upper end cover board 2, are connected between switch 9, accumulator 11 and motor 13 by electric wire.

A circular hole is equipped with positioned at the centre of lower end cover board 2, the rubber layer 1 of a sealing circular hole is fixedly mounted in circular hole；Tube body 5th, pipe 4 and cover board 2 are made of metal material, and add fastness and service life.

Operation principle：First the pipe of both sides is back-outed from tube body, as shown in Figure 1, at this moment, which is placed on tested The place of survey, and switch is opened, the opening of switch makes electrical power, and the rotation of motor has driven fan, can be effective by fan The air that script is located to tubular body blown out along gas vent from tubular body, while also make extraneous air along air inlet Hole enters in tube body, after continuing for some time, turns off the switch so that motor powers off, and a period of time is stood after power-off, makes pipeline Internal air precipitation, then, inwardly rotates the pipe of both sides, until the port of cover board and tube body is made to offset, so as to effective Air admission hole and gas vent are all screwed into tube body, by the aeroseal of tubular body, wherein, it can pass through rubber layer will by syringe The air extraction of tubular body, facilitates detection, wherein, since pipe is threadedly coupled with tube body so that can be by pipe from tube body Middle taking-up facilitates the cleaning to tube body.
