A kind of coal charging car-dedusting system protection device.
Background technology
In the charging coke coking production of top, charging car when carrying out top coaling operation, mixed coal enter after carbonization chamber by
Heat is decomposed, and a large amount of raw coke oven gas is generated, most of raw coke oven gas under the action of coalingging ground station for dust removal dedusting fan suction,
Into coal charging car-dedusting pipeline, wherein coal charging car-dedusting pipeline includes that bleeding device, dust leg, intermediate conduit are connected with dust
Pipe, is three-port structure at the top of dust leg, and top blind flange when normal operation at the top of dust leg is closed, and raw coke oven gas passes through
Coal charging car-dedusting pipeline enters dedusting manifold, finally enters ground station for dust removal deduster and is filtered, exhaust gas is discharged by chimney；It is few
It measures raw coke oven gas and enters gas gathering system under air blower effect.
But in the actual production process, two kinds of situations can be often encountered, first, burst has a power failure, the pressure stored by accumulator
It is not enough to effective cut-out that driving bleeding device carries out flue gas；Second is that dedusting fan is because disorderly closedown or rotating speed are too low, charging car
Dust pelletizing system is operated without any protective.It is reached a certain level in the case of this two kinds if air is mixed into raw coke oven gas, meeting
Cause heavy explosion, harmfulness very big.There is presently no effective ways to avoid the cleaning shaft caused in above-mentioned two situations quick-fried
It is fried.
Invention content
The present invention provides a kind of coal charging car-dedusting system protection devices, realize that raw coke oven gas exports dedusting by coordinated signals
Raw coke oven gas diffuses in the quick cut-out of pipeline and dust leg, avoids the cleaning shaft explosion of power-off or fan trouble initiation.
In order to achieve the above objectives, the scheme that the present invention takes is：A kind of coal charging car-dedusting system protection device, including with institute
The dust leg stated the dust connecting tube of dust pelletizing system total pipeline connection and be connected to the dust connecting tube by intermediate conduit, institute
It states intermediate conduit to be connected to the side of dust leg vertical section, the cover board that can be blocked, cover board is provided in the intermediate conduit
On be installed with the shaft I hinged with intermediate conduit, connecting rod I is vertically and fixedly provided in the shaft I, the lid surface is also associated with
The mechanism for opening/closing for driving it to be rotated along shaft I；Further include the top blind flange that the dust leg upper end can be sealed, the top cover
It is installed with the shaft II hinged with dust leg on plate, the connecting rod being connected with the connecting rod I by rope I is vertically and fixedly provided in shaft II
II, connecting rod I can realize the linkage of top blind flange when rotating, and angle with horizontal plane is less than 90 ° when top blind flange opening state, with true
When protecting rope I in relaxation state, top blind flange can be fallen under Gravitative Loads；It is fixed with pressure on the dust connecting tube side wall
Relay.
Preferably, the mechanism for opening/closing is the pneumatic linear actuator for connecting and carrying solenoid valve with cover board by rope II, to realize
The quick and precisely keying of cover board, reliable in action.
Preferably, the pneumatic linear actuator is vertically arranged, its piston rod bending deformation, the surface of pneumatic linear actuator and cover board are avoided
It is respectively arranged with fixed pulley II, the rope II can avoid pneumatic across described two fixed pulleys II, pneumatic linear actuator far from intermediate orbit
Element is damaged because of high temperature.
As an optimization, the lower section of the connecting rod I and connecting rod II is provided with fixed pulley I, the rope I is across the fixed pulley
I, change I angle of rope, connecting rod I is avoided rotation dead point occur.
As an optimization, rectangular cross-section of the intermediate conduit perpendicular to flue gas circulating direction, it is easier on off operating mode
Switching and sealing.
Preferably, the rope I, rope II are steel wire rope, keep it more firm in use, reliability is stronger.
Advantageous effect of the present invention：By the coordinated signals of top blind flange and cover board, cleaning shaft cut-out and waste coal are realized
The synchronous progress that gas diffuses, so as to avoid the raising of raw coke oven gas pressure；Dedusting suction in dust connecting tube does not reach setting
When value, dust leg will not be connected to dust connecting tube, avoid the possibility in the insufficient initiation accident of coalingging of suction.
Description of the drawings
