Embodiment
Embodiment, is shown in shown in Fig. 1 and Fig. 2: the sampling probe with self-cleaning function, comprises and connects block 10. This connection block 10 is provided with the air flue 11 of the upper and lower end face of this connection block 10 through, the lower port portion of this air flue 11 is connected with inlet pipe 20, upper end oral area is connected with air outlet adapter 30, this air outlet adapter 30 is connected with sampling tracheae 31, and this air outlet adapter 30 is furnished with filter core 40 prepared by stainless material. Obviously, this filter core 40 is for filtering dust, moisture and particle.
Concretely:
The left side being positioned at this air flue 11 in this connection block 10 is also provided with Venturi tube 12. That is, this Venturi tube 12 comprise under be arranged in order entrance section 121, bundle mouth section 122, larynx road 123 and expansion section 124. The spacing of the admission piece 50 being inserted with a doline in this entrance section 121, the opening portion outer rim of this admission piece 50 and the sidewall in this larynx road 123 is c. Certainly, best mode is, this admission piece 50 is positioned at the center position in this larynx road 123. Such as, this larynx road 123 is also circular. This admission piece 50 upper end is connected with cleaning compressed air source or compression source nitrogen 70. The bottom of this expansion section 124 is connected with waste pipe 60.
The upper left-hand face of this air flue 11 is provided with the baffle plate 111 extended to the right, has gap 112 between the right-hand member of this baffle plate 111 and the face, right side of this air flue 11, and the width in this gap 112 is a. Obviously, in order to guarantee the stable of gap 112 width, this air flue 11 passage that preferably cross section is square. The top being positioned at this baffle plate 111 in the left-hand face of this air flue 11 is provided with communicating aperture 113, and the height of this communicating aperture 113 is b.
The right side of this entrance section 121 is connected this communicating aperture 113. Meanwhile, the pass of the spacing c of the sidewall in the height b of the width a in this gap 112, this communicating aperture 113, the opening portion outer rim of this admission piece 50 and this larynx road 123 is: a��b��c.
Like this; gas in pneumatic tube enters this air flue 11 via this inlet pipe 20; afterwards; flow out from this sampling tracheae 31 via this filter core 40; macrobead dust wherein and steam are blown by the negative-pressure air-flow restrainting mouth section 122 place to be washed; then discharge through this waste pipe 60, greatly extend the work-ing life of this filter core 40. When the pressure in pneumatic tube is greatly about 50Kpa to 200kpa, the speed of sample gas can become slowly relative to the speed of the air-flow in pneumatic tube. Now, sample gas rising in the process of pneumatic tube top, macrobead and a large amount of dust, steam can because self gravitation reasons and be pulled to sample flow of air direction under Venturi principle effect, thus macrobead, a large amount of dust and steam in elementary removal sample gas. Remaining small-particle and little dust rise to this baffle plate 111 place on continuing, because the stopping cause of this baffle plate 111 stops in the lower section of this baffle plate 111, remaining sample gas enters into the top of this baffle plate 111 by this baffle plate 111 marginal gap 112, and a part by this filter core 40 enter sampling tracheae 31 for detecting, another part enters this bundle mouth section 122 place, and is expelled in original gas pipe line by this waste pipe 60 or other suitable safety zones.
Optimize:
The internal diameter of this inlet pipe 20 is 12 ~ 20mm, the internal diameter of tracheae 31 of sampling is 4 ~ 6mm, the internal diameter of waste pipe 60 is 8 ~ 20mm. Like this, it is ensured that this filter core 40 is had and suitable washes away dynamics.
Tubaeform big in outer end of this inlet pipe 20, the length of this inlet pipe 20 is at least 100mm. Like this, it is convenient to dock with pneumatic tube. Certainly, the inlet pipe 20 of flared structure and aforesaid sampling tracheae 31 itself also define the dust fall passage that has Venturi siphon function.
The foregoing is only preferred embodiment of the present utility model; not thereby patent scope of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all it is included in scope of patent protection of the present utility model with reason.
