Description
Technical field
The present invention relates to the dredgers in a kind of material transportation process, more particularly to a kind of material for making hopper
Convey unobstructed device.
Background technique
Raw coal bucket is the important component of coal-fired plant boiler coal handling system, generally uses the structures such as steel construction or steel reinforced concrete,
Circular upper part is square or cylinder, and lower part is leaned on certainly from top to bottom in circular cone or square cone, big upper and lower small mouth, raw coal particle
Density current is dynamic.Since section gradually tapers up, raw coal particle more flows downward, and extruding force is bigger, when raw coal is moist or blending coal slime
It easily causes coal dust to glue wall, knot arch, blocking, disconnected coal is caused, so that the stable operation of boiler is seriously affected, especially in plum rain season
It is even more serious.Currently, to solve the problems, such as run coal bin chute blockage, domestic and international power industry generally uses artificial tap dredge, install sky additional
Gas big gun, dither etc., can alleviate chute blockage phenomenon to a certain extent, but it is undesirable to dredge effect, especially to wet coal,
Tough coal etc. is even more to seem helpless, to bring very big inconvenience to production.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art to provide the dried shrimp song that a kind of structure is simple, dredging is high-efficient
The anti-blocking block clearing coal scuttle of line.
The present invention removes 5-8 meters above run coal bin lower section to feeder and changes dried shrimp curve coal scuttle into, and the dried shrimp is bent
Line coal scuttle lower part connects insertion plate door, plug-type sealed expansion joint is arranged between the insertion plate door and feeder, run coal bin is fallen
Coal pipeline section is inserted directly into feeder；2-8 silo wall vibrating air hammer, the dried shrimp are installed additional outside the dried shrimp curve coal scuttle
Manhole door, peep hole is arranged in curve coal scuttle headwall；The silo wall vibrating air hammer connects automatic filtering drainage device, in feeder
It is interior that disconnected coal signal pickup assembly is set；It is characterized by: being opened on dried shrimp curve coal scuttle headwall between insertion plate door and feeder
Dredger is arranged in hole, and the dredger includes decelerating motor, dredging bar, floating rule；The motor shaft of decelerating motor protrudes into hole
Interior, several floating rules are arranged on dredging bar in the end connection dredging bar of motor shaft；The decelerating motor, disconnected coal signal acquisition
Device connects electric cabinet.
The dredger be it is multiple, be arranged symmetrically on dried shrimp curve coal scuttle.
The floating rule is the triangular pelvis or straight-bar that end sets an inclined-plane, is more advantageous to and blows over material up and down.
The floating rule be right-angle triangle made of steel plate or iron plate, bevel edge be processed into cutting edge shape scrape pawl.
As shown from the above technical solution, the present invention changes in application, 5-8 meters of dismountings above run coal bin lower section to feeder
Cost apparatus.The dried shrimp curve coal scuttle of setting can reduce the drag and frictional force of the displacement of raw coal whereabouts, prevent chute blockage；What is be arranged inserts
Plate door is not easy chute blockage, and coal stream can be truncated, convenient to overhaul；The plug-type sealed expansion joint of setting can be relieved raw coal bucket due to
It expands with heat and contract with cold caused by climate change, and coal will not be hidden；The floating rule of motor shaft end connection is driven using the rotation of decelerating motor
It is rotated up and down, so that the material in coal scuttle is stirred up and down, avoids bonding, realize the unimpeded of material；Disconnected coal signal pickup assembly
Disconnected coal signal can be transmitted to electric cabinet automatically when detecting disconnected coal, by the operating of electric cabinet control decelerating motor, low energy consumption, object
Start automatically when material blocking, when material proper flow does not consume energy；The running fluffy coal of raw coal bucket, chute blockage phenomenon are efficiently solved,
It is mainly used for solving thermal power plant to be energy-saving and largely mix that the blocking of run coal bin caused by burning coal slime, lower coal are unsmooth etc. a series of to ask
Topic is also applied for the feed bin of other industry conveying materials.
