Abstract
The utility model relates to a gas sample sampling instrument, which is particularly suitable for the sampling of the chemical industry production and facility repair. The gas sample sampling instrument is a vacuum gas sampling apparatus using a miniature motor to drive a blade wheel to work and using the centrifugal manner to generate the negative pressure state at the point of a sampling port to suck the sample gas into a sample storing ball bladder. The gas sample sampling instrument is suitable for the collection of various gas samples with the temperature not higher than 60 DEG C. and the negative pressure smaller than 490 Pa.
Description
The utility model relates to a kind of safe collection equipment of gaseous sample, is specially adapted to the sampling of Chemical Manufacture and repair apparatus and uses.
The collection of gaseous sample is an important link for assay, should accomplish accurate, safety, timely, what each chemical enterprise generally adopted at present is the bulbs,double sampling thief, in use, and repeatedly by squeezing the power ball, gaseous sample is sucked in the air bag, and output is used for analytical test again.Chinese patent 86210944 has been introduced a kind of safe bulbs,double, on the air inlet port of its power ball, a safety that is made of one with its air inlet check (non-return) valve is installed connects mouth, connect the thin sebific duct that connects different length on the mouth respectively at this on demand again, so that can in container, take out the gas sample easily.
Prior art is that the restorability by means of the rubber sphere of extruding produces negative pressure, gaseous sample is sucked and passes to air bag, finishes sampling process.Owing to be manual squeezing power ball, reciprocal time is long, makes people's fatigue easily, and labour intensity is big, and sample rate is slow.Limited because of the recuperability of power ball, sampling is not easy very much to the sample under the negative pressure (98Pa).Bulbs,double is a rubber in addition, through a period of time with after chemical gases contacts, aging corrosion phenomenon easily takes place, influence the sealing effectiveness of each coupling part, the accuracy of sampling is difficult to guarantee.
The purpose of this utility model, be to change the operating process of manual compression bulbs,double, a kind of micro-machine impeller work that utilizes is provided, produce the negative pressure state at thief hatch place with centrifugation, draw sample gas and enter vacuum type gas sampler in the sample storing sphere bladder, so that reach laborsaving, quick, gather all gases sample accurately, safely.
Formation of the present utility model is: adopting axial seal formula motor is power source, can be equipped with battery, also can directly connect power supply, motor (7) places seal box (8) fixing with screw (5) and impeller casing (2), control by switch, after connecting with the mains by power lead (9), starter motor (7) impeller (4) rotation, finish the isolation of sample and motor (7) by O-ring seal (6), suction inlet (1) is connected with impeller casing (2) (also can directly make one) with the silk mouth with the joint of sending mouthful (3), suction inlet (1) and send mouthful (3) and be thread a mouth or a corrugated form.
Fig. 1 is the structure dissection synoptic diagram.
In conjunction with the accompanying drawings and embodiments, the invention will be further described.
For easy to use and raising intake capacity, select for use micro-machine and impeller and the safety power supply to be complementary, motor is the sealingly secure voltage-type, and impeller will have certain intensity, heatproof is indeformable more than 60 ℃, availablely etch-proofly moulds firmly, nylon, organic glass or lightweight metal material make.Power supply be can output safety voltage small articles, can power continuously more than 2 hours, and be easy to assembling and carry.
Contact with motor for fear of flammable, chemical gases sample, motor (7) is placed closed state, and the certain excessively space of two square tubes about impeller blade is connected, guarantee that with this motor is not corroded, and can prevent that spark that the brush of once-through type motor uses aging back to produce from not contacting with inflammable gas and cause danger.Suction inlet (1) selects the silk shape of the mouth as one speaks or ripple type to guarantee to be connected with the effective of connecting pipe with the joint of sending mouthful (3), impeller casing (2) and joint are selected for use firmly and are moulded, nylon, organic glass or lightweight metal material processing and fabricating, are configurable handle easy to carry or braces.
Because the utility model has changed the operating process of manual compression bulbs,double, a kind of vacuum type gas sampler is provided, the sample man is reduced labor intensity greatly, sample rate improves more than 2 times, can gather all gases sample below 60 ℃, because negative suction can reach 830Pa, so generally can adopt flue gas and all gases sample under the negative pressure 490Pa situation, reaching laborsaving, quick, gather the effect of gaseous sample accurately, safely, is a kind of collection equipment of desirable gaseous sample.
Claims (3)
1, a kind of vacuum type gas sampler, it is characterized in that: motor (7) places seal box (8) fixing with screw (5) and impeller casing (2), through switch control power lead (9), connect with the mains, starter motor (7) impeller (4) rotation, finish the isolation of gaseous sample and motor (7) by O-ring seal (6), suction inlet (1) is connected with impeller casing (2) (also can directly make one) with the silk mouth with the joint of sending mouthful (3), suction inlet (1) and send mouthful (3) and be thread a mouth or a corrugated form.
2, vacuum type gas sampler according to claim 1 is characterized in that: motor (7) adopts the motor of axial seal formula, safe voltage type.
3, vacuum type gas sampler according to claim 2 is characterized in that: impeller (4) wants heatproof indeformable more than 60 ℃, by etch-proofly mould firmly, nylon, organic glass or lightweight metal material make.
