Description
Technical field
The present invention relates to a kind of optic probe anti-fouler measured for Geldart-D particle powder parameters.
Background technology
Geldart-D particle is a kind of effective ways utilizing air-flow conveying granular solid in the duct, and be widely used in the powder conveying of various industrial sector, such as, in thermal powerplant, solid fuel is as the Cemented filling of coal dust etc.Such as the accurate on-line measurement of granularity, speed etc. of Geldart-D particle powder parameters has great importance to ensureing production safety and enhancing productivity.In Geldart-D particle powder parameters is measured, existing method of measurement comprises sieve method, acoustic method, electrostatic method and optical method etc.Compared to other method of measurement, optical method has intuitive measurement results, subsequent treatment is simple, survey precision is high advantage.But, also there is a significant problem---when being with powder to run, fine powder particle easily pollutes optic probe, thus making optic probe be difficult to obtain actv. measurement signal, this becomes a bottleneck problem of the technical application of restriction Geldart-D particle powder parameters measuring method.At present, after fine powder particle contamination optic probe, generally directly change optic probe or dismantle optic probe and carry out manual finishing.This scheme cost is higher, and is unfavorable for the continuous on-line measurement realizing powder parameters.
For solving the problem of subparticle pollution optic probe in ubiquitous pipeline in Geldart-D particle powder parameters optical measurement process, the present invention proposes a kind of optic probe anti-fouler measured for Geldart-D particle powder parameters, when being with powder to run, still can effectively carry out antifouling to optic probe flexibly, thus each optic probe can be made when being with powder to run to keep clean, thus the technical application of Geldart-D particle powder parameters measuring method is made to become possibility.
Summary of the invention
The object of the present invention is to provide a kind of optic probe anti-fouler measured for Geldart-D particle powder parameters.For realizing object of the present invention, the present invention by the following technical solutions.
A kind of optic probe anti-fouler for the measurement of Geldart-D particle powder parameters comprises pedestal, optic probe, probe head wall, pipeline, compression indicator and electrically-powered actuator, it is characterized in that: described probe head wall is provided with induction opening, be provided with auto door in described pedestal, described auto door can horizontally slip under the drive of electrically-powered actuator in pedestal.
Described induction opening is connected with external pressurized air, and induction opening is uniformly distributed along probe head wall, to ensure even air inlet, thus forms uniform air conservation layer on optic probe surface, prevents subparticle from polluting optic probe.
Be provided with sealing arrangement between described auto door and pedestal, to ensure the leak tightness of optic probe anti-fouler, thus prevent powder in pipeline by gap leakage to outside pipeline.Described auto door is square, and its length of side is greater than the diameter of optic probe.
Described pedestal, auto door are made by high-abrasive material, with the wear resisting property of intensifier.
Described pedestal is divided into upper and lower two parts, is connected by screw between upper and lower two parts, for being flexibly connected, to reach the object dismantling and be convenient for changing parts flexibly.
Beneficial effect of the present invention: 1) can carry out antifouling to optic probe when being with powder to run, thus ensure that the real-time that powder parameters is measured and accuracy.2) adopt pressurized air and auto door double protection, enhance the reliability of protection.
