Offering connecting hole on pulverized coal channel, described seal sleeve is placed on described connecting hole, and described center-pole inserts in described seal sleeve
In, described center-pole and described connecting hole compress described seal sleeve jointly.
Further, the sleeve that described seal sleeve is made up of rubber, described sleeve has and is inserted into described connecting hole
Interior cylindrical portion encloses flange with the one of the outer wall being close to described pulverized coal channel.
Further, described cylindrical portion is cylindrical pipeline section shape, and the difference of its internal diameter and external diameter is 0.8-5 centimetre, institute
It is ring-type for stating flange, and the thickness of described flange is 0.5-3 centimetre, and the difference of the external diameter of described flange and the external diameter of described cylindrical portion is
1-6 centimetre.
Further, the internal diameter of described cylindrical portion and the difference of external diameter are 1.5 centimetres.
Further, the thickness of described flange is 1.5 centimetres.
Further, the difference of the external diameter of the external diameter of described flange and described cylindrical portion is 2 centimetres.
By such scheme, this utility model at least has the advantage that microwave method coal powder density of the present utility model exists
Line is measured the mounting structure of sensor and is mainly socketed in the connecting hole of pulverized coal channel by seal sleeve, then by sensor grafting
In seal sleeve, it is achieved sensor is connected with the splicing type of pulverized coal channel, coal dust free is revealed, it is easy to the installation of sensor, dimension
Repair and change, pulverized coal channel and sensor, more emat sensor will not be destroyed without shutting down.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
