Abstract
The utility model discloses a fixing device of a fly ash constant speed sampling gun, and the technical problem that because an existing fixing device of the fly ash constant speed sampling gun is instable, fly ash is not representative is solved. The fixing device comprises an upper end hole (3) and a lower end hole (2) which are communicated and arranged in a cylindrical sleeve (1), a sampling pipe (4) is connected in the lower end hole (2) of the cylindrical sleeve (1) in a sleeved mode, and a sampling gun (9) is arranged in the cylindrical sleeve (1) and the sampling pipe (4). A pair of sampling pipe fixing screw holes (5) is symmetrically formed in the outer side pipe wall of the lower end hole (2) of the cylindrical sleeve (1), sampling pipe fixing jackscrews are (6) are arranged in the sampling pipe fixing screw holes (5), a sampling gun fixing screw hole (7) is formed in the outer side pipe wall of the upper end hole (3) of the cylindrical sleeve (1), and a sampling gun fixing jackscrew (8) is arranged in the sampling gun fixing screw hole (7). The fixing device of the fly ash constant speed sampling gun is convenient to disassemble and carry, and suitable for meeting performance test requirements of boilers of different types.
Description
Technical field
The utility model relates to a kind of fixing device of smoke dust sampling gun, particularly a kind of fixing device of fly ash constant speed smoke dust sampling gun.
Background technique
At present, when the station boiler performance test is carried out the fly ash constant speed sampling, because the sampling rifle reaches about 4 meters, and material is stainless steel, and component is heavier, and the sampling rifle rocks easily in the sampling process, make sampling hole and flow of flue gas direction produce deviation, the flying dust that causes sampling to obtain is not representative.
Summary of the invention
The utility model provides a kind of fly ash constant speed sampling rifle fixing device, and the fixing device shakiness that has solved existing fly ash constant speed sampling rifle causes the not representative technical problem of flying dust.
The utility model is to solve above technical problem by the following technical programs:
A kind of fly ash constant speed sampling rifle fixing device, be included in the sampling pipe that arranges in the station boiler thieff hatch and the cylinder-shaped sleeve of being with T shape step, in cylinder-shaped sleeve, be provided with upper end hole and the following stomidium of connection, sampling pipe is socketed in the following stomidium of cylinder-shaped sleeve, the sampling rifle is arranged in cylinder-shaped sleeve and the sampling pipe, on the outside tube wall of the following stomidium of cylinder-shaped sleeve, be provided with a pair of sampling pipe fixing threaded hole symmetrically, in the sampling pipe fixing threaded hole, be provided with fixedly jackscrew of sampling pipe, the outside tube wall of the upper end hole of cylinder-shaped sleeve is provided with sampling rifle fixing threaded hole, is provided with fixedly jackscrew of sampling rifle in sampling rifle fixing threaded hole.
The sampling head of sampling rifle arranges over against the flue gas flow path direction.
The utility model is convenient to dismounting, is carried, and is applicable to dissimilar boiler performance test demands, uses the utility model can make the flying dust sample that samples have higher representativeness, has reduced sample collector's labor intensity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
