Description
Technical field
The utility model belongs to a kind of coal scuttle raw coal blanking device more particularly to a kind of coal scuttle multistage blockage-clearing device.
Background technology
There are long-term existence chute blockage problems more than half in domestic thermal power plant, greatly threatens the normal fortune of power plant
Battalion, reduces generated energy, while having directly influenced the economic benefit of power plant.It is maintained most in a manner of oil firing after run coal bin chute blockage
Underload or maintenance heat supply are power plant's widespread practices.After chute blockage, some power plant crew sets out, and be on duty reply day and night, strikes
Coal scuttle, crooked chisel bucket coal, but efficiency is low, and effect is poor.The process production that manual cleaning run coal bin blocks pollutes ring at great dust
Border, has also threatened the health of personnel, and fuel oil then causes the excessive loss of the energy.In conclusion in order to reduce pollution,
Develop safe efficient, energy-saving and environmental protection electric utilities, solves the problems, such as that thermal power plant chute blockage is very urgent.
The common chute blockage region of run coal bin, typically occurs in from run coal bin lower part cone bucket to the position between feeder entrance
Set, within the scope of this, due to run coal bin be static side cone, inverted cone, hyperbola, irregular multiaspect joint body structure or
The reasons such as washiness in raw coal, viscosity is larger, cause no matter raw coal occurs to bond and accumulation at any one position, can all cause
At this raw coal internal friction increase, then radially with it is axially extending, ultimately form blocking.
It is typically all to install the local dredging devices of more sets in bulkhead that power plant, which handles run coal bin blockage problem, dredging device without
When method is dredged, it must just be dredged using artificial percussion mode.Run coal bin cone bucket partially due to long-term percussion energetically is deformed,
Keep surface more and more coarse.Coarse surface increases raw coal and blocks probability, forms vicious circle.Part run coal bin due to the use of
Older, long-term corrosion and abrasion, the skin-friction coefficient being more the increase in coal bunker inside headwall make in raw coal dropping process
By larger frictional resistance, and moist sticky larger coal is easier to be adhered on the bigger run coal bin inner wall of frictional force,
Make the accumulation situation aggravation of part coal bunker inner surface, increases the frictional resistance of raw coal whereabouts, cause stopping state increasingly severe.

The operation principle of the utility model is：
This coal scuttle multistage blockage-clearing device is that I improves at company according to domestic automatic control level, in conjunction with domestic thermal power generation electricity
Chute blockage situation present in all kinds of run coal bin actual motions of factory reduces labor intensity in response to safety in production and is designed.This
Coal scuttle multistage blockage-clearing device is installed on mouth under run coal bin and is easy chute blockage section, and automation is realized with to coal demand according to the storage of raw coal
Block clearing, anti-blocking, highly reliable blockage-removing device of coal bucket.
This coal scuttle multistage blockage-clearing device by automate every grade of high-frequency excitation motor oscillating of independent control time cycle, one
As from bottom to top substep carry out block clearing, block clearing is comprehensively without dead angle, and every grade of blockage-removing device of coal bucket ontology is down through elastic packing knot
Structure connects, and amplification amplitude is played in this connection, while discharging exciting dynamics, avoids transmitting exciting to the structure of other connections
Power also avoids that the effect that resonance destroys equipment occurs.This coal scuttle multistage blockage-clearing device is avoided due to carrying out block clearing from bottom to top
Unordered block clearing, unordered block clearing are mainly reflected in when common coal bucket block-clearing machine installation vibration, rapping：1. only right in local block clearing
The block clearing of device installation region and can not precisely remove stifled point, in whole block clearing, coal cannot achieve clear from bottom to top in coal scuttle
It is stifled.Unordered block clearing cause can not effective block clearing, sometimes aggravate chute blockage probability.
When this coal scuttle multistage blockage-clearing device normal operation, occur coal stream be detained or knot it is stifled after, feeder 13 detects disconnected coal
Afterwards, coal scuttle multistage blockage-clearing device starts three-level dither motor 10, three-level automatically first, in accordance with the time cycle being previously set
Dither motor 10 drives 9 entirety of three-level blockage-removing device of coal bucket ontology and wall surface high-frequency excitation after starting, carried out to this section complete
Face block clearing；Then start two level dither motor 6 automatically, two level dither motor 6 drives two level blockage-removing device of coal bucket sheet
7 entirety of body and wall surface high-frequency excitation carry out comprehensive block clearing to this section；Last automatic startup level-one dither motor 4, level-one is high
Frequency vibration motor 4 drives 3 entirety of level-one blockage-removing device of coal bucket ontology and wall surface high-frequency excitation, and comprehensive block clearing is carried out to this section.
The blockage-clearing device ontology of multistage includes height each other by flanged joint between the upper flange and lower flange of docking
Intensity rubber.The technique effect and its realization process for the essence that the technical solution at this place is played are as follows：High-strength rubber carries
For the basic structure of vibrations, facilitate whole vibrations.
A kind of fixed structure of high-frequency electric machines presented below, similar realization structure in the protection domain of this patent,
Include fixed plate on the blockage-clearing device ontology of multistage, fixed plate can fix dither motor.
In a creative way, above each effect is individually present, moreover it is possible to the combination of the above results is completed with a nested structure.
It is clear that the technique effect that the above structure is realized is realized, if the additional technical solution is not taken into account, this patent title is also
It can be a kind of blockage-clearing device.It is not shown in figure part details.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
It restricts, but it can also be combined with each other in the absence of conflict, reach multiple effects and realize jointly.
Basic principles, main features, and advantages of the present invention has been shown and described above.Ability
The technical staff in domain should be recognized that the present utility model is not limited to the above embodiments, described in the above embodiment and specification
