The anti-adhesion sampling head has a simple structure, and is convenient to detach and use.
Description
Technical field
The present invention relates to a kind of sample devices that is used for the heat power plant boiler flue dust, particularly a kind of smoke dust sampling head of smoke dust sampling gun.
Background technology
Smoke dust sampling is the important step of boiler and performance of precipitator test and environment protection and monitoring test; at boiler smoke; in fume emission test and the environment protection and monitoring; smoke dust sampling will be sampled under the different position of boiler flue stops as required; because boiler smoke high temperature contains wet; and sampling head present position condition is changeable; the smoke dust sampling filter cylinder is made moist contain wet; stick together with the sampling head that compresses back and smoke dust sampling gun fastening; after causing sampling work to finish; win sampling filter cylinder difficulty; and make non-sampling impurity adhere on the sampling filter cylinder or make filter cylinder adhesion breakage, cause the sample of filter cylinder can not be true; reflect actual conditions and result exactly.
Summary of the invention
The sampling head that the anti sampling head of a kind of smoke dust sampling gun provided by the invention has solved existing sampling filter cylinder and smoke dust sampling gun sticks together, after causing sampling work to finish, win sampling filter cylinder difficulty, and make non-sampling impurity adhere to the sampling filter cylinder on or make filter cylinder adhesion breakage, the sample that causes sampling can not reflect actual conditions and result truly, exactly.
The present invention solves above technical matters by the following technical programs:
A kind of anti sampling head of smoke dust sampling gun, comprise tubular smoke dust sampling head main body, the tubular filter cylinder frame that has square hole on the wall, flue dust inlet end set collar and sampling head inlet end lid, described tubular filter cylinder frame is movably arranged in the tubular smoke dust sampling head main body, the annular that the porch of tubular filter cylinder frame is provided with prominent along with movable cooperation of ring groove that on the porch of the inwall of tubular smoke dust sampling head main body, is provided with, sampling head inlet end lid links together by the inlet of flue dust inlet end set collar and tubular smoke dust sampling head main body, the porch madial wall of tubular filter cylinder frame is provided with the semicircle antiseized line of concavity of netted arrangement, the capping plug of sampling head inlet end lid is provided with annular groove, and the capping plug that has the sampling head inlet end lid of annular groove is plugged on the inboard activity of the inlet of the tubular filter cylinder frame of the semicircle antiseized line of the concavity that has netted arrangement; On the inside and outside sidewall of tubular filter cylinder frame, all scribble the Te Folong anti-stick coating, on the capping plug of sampling head inlet end lid, scribble the Te Folong anti-stick coating.
In described tubular filter cylinder frame, be placed with glass fibre sampling filter cylinder; Described flue dust inlet end set collar and tubular smoke dust sampling head main body link together by threaded engagement.
The present invention is simple in structure, easy disassembly, solved existing flue dust (gas) sample devices and given birth to adhesion at long-time sampling post-sampling filter cylinder and smoke dust sampling hair, on adhesion such as iron rust slag point and the sampling filter cylinder or make filter cylinder adhesion breakage, to making sampling filter cylinder weight that improper change cause sampling failure or influence the technical matters of sampled result take place, improve sampling quality, be suitable for various smoke dust sampling equipment.
