Abstract
A pulverized coal sampling device comprises a pulverized coal pipe; the pulverized coal pipe is connected with a sampling pipe in an exhaust pipe through a ball valve and a lead screw; an inner end of the sampling pipe is connected with a handwheel; an outer end of the sampling pipe is communicated with a separator; a collecting bottle is arranged at the lower part of the separator; and after a gate valve is opened and the sampling pipe is swept by compressed air, the gate valve is closed, the handwheel is shaken to enable the sampling pipe to enter the center of the pulverized coal pipe through the ball valve, and pulverized coal passes through the sampling pipe and the separator and flows into the collecting bottle. The pulverized coal sampling device has the characteristics of simple structure, simplicity in operation and good air tightness.
Description
Technical field
The utility model relates to a kind of coal fines sampling apparatus.
Background technology
The fineness of pulverized coal analysis is an indispensable analysis project in boiler operatiopn monitoring and the pulverized coal preparation system experiment; Existing coal fines sampling apparatus is fixed sampler; Because stopple coupon is fixed in the pulverized coal channel; On pulverized coal channel, be provided with opening, coal dust constantly emits through opening outward, can cause blast pipe to stop up.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of the utility model 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 scheme that the utility model adopts is: a kind of coal fines sampling apparatus; Include pulverized coal channel, pulverized coal channel links to each other with stopple coupon in being located at blast pipe through ball valve and leading screw, and the inner of stopple coupon links to each other 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 through gate valve.
The packing_seal device is adopted in described blast pipe and ball valve junction.
Compared with prior art, the utility model 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 the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Referring to accompanying drawing, a kind of coal fines sampling apparatus includes pulverized coal channel 1; Pulverized coal channel 1 links to each other with stopple coupons 4 in being located at blast pipe 3 through ball valve 2 and leading screw; The inner of stopple coupon 4 links to each other 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 through gate valve 9.
Described blast pipe 3 adopts the packing_seal device with the ball valve junction.
The principle of work of the utility model is:
During use, after opening gate valve and with pressurized air stopple coupon being purged, closing gate valve shakes handwheel and makes stopple coupon pass through ball valve to get into the pulverized coal channel center, and coal dust flows into receiving flask through stopple coupon, separation vessel.
