Description
Technical field
The utility model 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 utility model 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 purpose of this utility model is to provide a kind of optic probe anti-fouler measured for Geldart-D particle powder parameters.For realizing the purpose of this utility model, the utility model 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.
The beneficial effects of the utility model: 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.

Detailed description of the invention
Fig. 1 is theory structure schematic diagram of the present utility model.As shown in Figure 1, this optic probe anti-fouler comprises pedestal 1, optic probe 2, probe head wall 3, pipeline 4, compression indicator 5 and electrically-powered actuator 6, it is characterized in that: described probe head wall 3 is provided with induction opening 7, be provided with auto door 8 in described pedestal 1, described auto door 8 can horizontally slip under the drive of electrically-powered actuator 6 in pedestal 1.Described induction opening 7 is connected with external pressurized air, and described induction opening 7 is uniformly distributed along probe head wall 3, to ensure even air inlet, thus forms uniform air conservation layer on optic probe surface.
Part sectional view when Fig. 2 and Fig. 3 is the opening and closing of the utility model auto door.When compression indicator records the pressure that external compressed air pressure is greater than in pipeline, auto door in the drive lower slider of electrically-powered actuator to the low order end of pedestal, now auto door is in opening, can be measured by optic probe to the powder parameters in pipeline.Now external pressurized air is by the even air inlet of induction opening, forms uniform air conservation layer on optic probe surface, prevents powder granule from polluting optic probe.When compression indicator records the pressure that external compressed air pressure is less than in pipeline, auto door slides into rapidly the high order end of pedestal under the drive of electrically-powered actuator, and now auto door is in closed condition, prevents the powder granule in pipeline from polluting optic probe.Sealing arrangement is provided with, to prevent in pipeline subparticle by gap leakage to pipeline external between described auto door and pedestal.
Fig. 4 is the utility model auto door schematic shapes, and described auto door is square, and its length of side is greater than the diameter of optic probe, to reach the effect of available protecting optic probe.
Preferably, 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.
Preferably, described pedestal and auto door are made by wear-resistant steel material, to strengthen the wear resisting property of optic probe anti-fouler, thus extend its service life.
By reference to the accompanying drawings detailed description has been done to embodiment of the present utility model above, but the utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, many variations can also be made to it.But these changes, do not make the essence of appropriate technical solution depart from the spirit and scope of the utility model embodiment technical scheme.Protection domain of the present utility model is worked as the scope limited depending on proposed claim and is as the criterion.
