Description
Technical field
The utility model is related to thermal power generating technology fields, and in particular to a kind of feeder coal dropping port and feeder.
Background technology
The characteristics of China's energy resources is rich coal, oil starvation, few gas, and coal all will be within suitable long-term at present and in the future
China's energy resource structure is dominated.Pulverized-coal fired boiler is the main with one of coal equipment, the necessity of feeder as pulverized-coal fired boiler of China
Equipment Requirement amount is very big.
But due to friction coefficient between the coal of different coals quality and different from the friction coefficient of coal dropping port, friction coefficient is got over
Greatly, coal is easier is trapped on coal dropping port.When coal is in certain humidity, under the gravity of day-coal, between coal and coal
And the frictional force between coal and coal dropping port increases, and a large amount of fluffy coals have been bonded on coal dropping port, to form chute blockage basis ---
Hole skewback plinth.Because chute blockage basis certainly exists, when the volume on chute blockage basis is increasing, it is sticked to coal on coal dropping port liner plate
Thickness is constantly increasing.Core stream is more and more thinner, and coal is unsmooth under occurring, final chute blockage phenomenon.The speed that hole skewback plinth is formed determines
The frequency of coal bunker chute blockage.
It can only fall fluffy coal after chute blockage occurs for feeder using manually being beaten to shake with sledgehammer, can not be given birth at feeder at present
It is handled while production；And artificial treatment is laborious, time-consuming, effect is poor.
Utility model content
The purpose of this utility model is to solve the problems, such as that chute blockage easily occurs for the coal dropping port of existing feeder, and provide one kind to coal
Machine coal dropping port and feeder.
To achieve the above object, technical solution provided by the utility model is：A kind of feeder coal dropping port, including by up to
Under the top hopper, middle part hopper and the lower part hopper that are sequentially connected, the transition junction of the top hopper and middle part hopper is set
There is gate valve；It is characterized in that the inner wall of the middle part hopper is equipped with loosening apparatus；The loosening apparatus includes receiver
And the oil cylinder being arranged in receiver and loose bar, one end of the oil cylinder are packed on the bottom plate of receiver, it is described loose
One end of bar and the piston rod of oil cylinder are connected；The other end stretches out the receiver.
Further, in order to expand the working face of loosening apparatus, working efficiency is improved, the above-mentioned loose bar of receiver is stretched out
Multiple loose plates perpendicular to it are equipped with, the loose plate two is one group of both sides for being symmetricly set on the loose bar, more
The loose plate interval setting of group, the loose plate are arc and are bonded with the inner wall of the middle part hopper.
Further, in order to which loosening apparatus reduces the resistance being subject to when operation, ensure the flexible resistance of loose bar, improve and dredge
The service life of loose bar, along oil cylinder to the top orientation of loose bar, the length of above-mentioned loose plate is gradually reduced.
Further, in order to reach preferably thin coal effect, the inner wall of above-mentioned top hopper is equipped with vibrator, and cooperation is dredged
Loose device works together.
Further, above-mentioned loosening apparatus is four, and two of which is disposed adjacent as a set of, in two sets loosening apparatus edges
Portion's hopper central axis is symmetrical arranged.
A kind of feeder, is characterized in that, including above-mentioned feeder coal dropping port.
The utility model has the beneficial effects that：
1, the utility model installs loosening apparatus in feeder coal dropping port, pumps, cuts along coal bunker inner wall
Cohering for disconnected coal and coal bunker, destroys canopy coal supporting point, directly destroys chute blockage basis hole arch, efficiently solve what coal dropping port blocked
Problem, reduce coal under feeder coal dropping port it is unsmooth, even chute blockage phenomenon occur, improve the reliable of feeder continuous operation
Property.
2, loosening apparatus provided by the utility model is simple in structure, installation operation is convenient, using automated production, effectively carries
High working efficiency, reduces labor intensity.Due to using hydraulic drive, reliability is high, operates steadily, and failure rate is low, ties up
Shield is convenient.
3, top hopper side wall of the utility model also above loosening apparatus installs vibrator, in loosening apparatus and rapping
Under device collective effect, canopy coal point is destroyed, has reached preferably thin coal effect.
