Abstract
A coal dust sampling device comprises a coal dust pipeline. The coal dust sampling pipeline is connected with a sampling pipe which is arranged inside an air-emitting pipe through a ball valve and a lead screw. The inner side of the sampling pipe is connected with a hand wheel. The outer end of the sampling pipe is communicated with a separator. A collecting bottle is arranged on the lower portion of the separator. A gate valve is opened to sweep the sampling pipe with compressed air, the gate valve is closed, the hand wheel is swung to enable the sampling pipe to enter the center of the coal dust pipeline through the ball valve, and coal dust is flown into the collecting bottle through the sampling pipe and the separator. The coal dust sampling device has the advantages of being simple in structure, simple to operate, and good in seal performance.
Description
Technical field
The present invention relates to a kind of coal fines sampling apparatus.
Background technology
The fineness of pulverized coal analysis is indispensable analysis project in boiler operatiopn monitoring and pulverized coal preparation system experiment, existing coal fines sampling apparatus is fixed sampler, because stopple coupon is fixed in pulverized coal channel, be provided with opening on pulverized coal channel, coal dust constantly emits outward by opening, can cause blast pipe to stop up.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of coal fines sampling apparatus, have simple in structure, the characteristics of simple to operate and good airproof performance.
To achieve these goals, the technical solution used in the present invention is: a kind of coal fines sampling apparatus, include pulverized coal channel, pulverized coal channel is connected with stopple coupon in being located at blast pipe by ball valve and leading screw, the inner of stopple coupon is connected with handwheel, the outer end of stopple coupon is connected with separation vessel, and the bottom of separation vessel is provided with receiving flask.
Described separation vessel top also is provided with injector, and injector communicates with compressed air piping by gate valve.
Described blast pipe and ball valve junction employing packing_seal device.
Compared with prior art, the present invention adopts leading screw to advance, and can make stopple coupon go deep into the coal pipe sampling core, and distinctive packing_seal device guarantees that coal dust does not emit outward, have simple in structure, the characteristics of simple to operate and good airproof performance.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Referring to accompanying drawing, a kind of coal fines sampling apparatus includes pulverized coal channel 1, pulverized coal channel 1 is connected by ball valve 2 and the leading screw stopple coupon 4 interior with being located at blast pipe 3, the inner of stopple coupon 4 is connected with handwheel 5, and the outer end of stopple coupon 4 is connected with separation vessel 6, and the bottom of separation vessel 6 is provided with receiving flask 7.
Described separation vessel 6 tops also are provided with injector 8, and injector 8 communicates with compressed air piping by gate valve 9.
Described blast pipe 3 and ball valve junction employing packing_seal device.
Principle of work of the present invention is:
During use, after opening gate valve and with pressurized air, stopple coupon being purged, closing gate valve shakes handwheel and makes stopple coupon enter the pulverized coal channel center by ball valve, and coal dust flows into receiving flask through stopple coupon, separation vessel.
