Description
Technical field
The utility model relates to a kind of electric power subsidiary engine, the latent arm-type fixedly coal fines sampling apparatus of coal dust sampling on the particularly a kind of wind powder feeding pipes that is used for pressurized direct pulverizing coal system.
Background technology
Fixing coal fines sampling apparatus is the regular specialized equipment of sampling on a kind of wind coal pipe that is used for the coal-fired power station boiler unit pulverized-coal system.This equipment adopts pressurized air suction principle, and sample rate is adjustable, and sampling accurately; And the coal dust free leakage problem produces, and pollution-free, the advantage that labour intensity is little is widely used.But there is a shortcoming in this sampler, is exactly that sampling pipe directly is in the pulverized coal channel, even stopple coupon does not also stop when not working like this is washed away by breeze airflow, thereby has shortened serviceable life.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provide a kind of simple to operate, improve stopple coupon life-span, safe and practical latent arm-type fixedly coal fines sampling apparatus.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of latent arm-type fixedly coal fines sampling apparatus, comprise the stopple coupon, coal powder collection pipe and the compressed air hose that are provided with sample tap, be provided with blow down valve, air ejector, compressed air regulating valve, compressed air control valve on the described compressed air hose successively, described coal powder collection pipe is provided with sample valve, cyclone separator, the cyclone separator below is connected with sampling jar, the outlet of cyclone separator connects air ejector by pipeline, and the coal powder collection pipe is connected with stopple coupon; Be characterized in: on stopple coupon, be connected with operating grip; It also is provided with the cover cap that covers stopple coupon, and described cover cap is fixed on the pulverized coal channel of supporting sampling, and the pulverized coal channel that is positioned at cover cap is provided with the sampling passage that passes in and out for stopple coupon, is connected with the operating grip steady arm on the cover cap; Compressed air hose is connected with cover cap.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Latent arm-type fixedly coal fines sampling apparatus is characterized in: described steady arm is the location handwheel.
When needing sampling, pull operating grip, the stopple coupon that is placed in the cover cap produces rotation, and enters in the pulverized coal channel by the sampling passage on the pulverized coal channel, make sample tap face toward breeze airflow to, open all valves then and begin sampling.After sampling finishes, pull operating grip with in the stopple coupon cycle cover cap.Compared with prior art, the utility model is simple to operate, and is safe and practical, effectively avoided breeze airflow to the washing away of stopple coupon when not taking a sample, thereby improved the stopple coupon life-span.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
